    Dynamic simulation of solar water heating system using supercritical CO2 as mediating fluid under sub-zero temperature conditions2019In: Applied Thermal Engineering, ISSN 1359-4311, E-ISSN 1873-5606, Vol. 161, article id 114152Article in journal (Refereed)
    Abstract [en]

    CO2 is becoming increasingly important as a mediating fluid, and simulation studies are indispensable for corresponding developments. In this study, a simulation-based performance investigation of a solar water heating system using CO2 as a mediating fluid under sub-zero temperature condition is performed using the TRNSYS® software. The maximum performance is achieved at a solar savings fraction of 0.83 during July. The as lowest solar savingss fraction of 0.41 is obtained during December. The annual heat production of the proposed system under Fargo climate is estimated to be about 2545 kWh. An evacuated glass tube solar collector is designed, fabricated and tested for various climate conditions. Moreover, a detailed comparison of the system's performance at sub/supercritical and supercritical pressures shows that the annual heat transfer efficiency of the modeled system is 10% higher at supercritical pressure than at sub/supercritical pressures. This result can be attributd to the strong convection flow of CO2 caused by density inhomogeneities, especially in the near critical region. This condition resuls in high heat transfer rates.

    Title:                        Dividend in close companies

    Keywords:              Dividend, qualified shares, the canceled proposition 2017, tax behavior

    Research

    Questions:               What possible changes in behavior has the cancelled proposition generated at decision making in close companies?

                                     What impact do tax reforms have on tax behavior?

    Purpose:                  The purpose of the survey is to create an understanding about if and how close companies have acted towards the rejected proposition of change in the 3:12 rules. In addition to this, the purpose is also to create an understanding of what impact tax reforms have on tax behavior.

    Method:                   Regulations regarding dividend opportunities in close companies, have been collected and analyzed. Theoretical data collection on reformers' impact on tax behavior has been collected. In addition, interviews have been conducted with owners of close companies and authorized auditors.

    Conclusion:              The proposition of change that were rejected in the summer of 2017 had no significant impact on majority of the shareholders at close companies. This is due to complicated regulations. In specific cases, when reforms are too complicated, it requires the involved partners a learning time to acquire new knowledge and therefore do not have the time or knowledge to respond to the reform requirements.

    Hur påverkar logistikplaneringen byggarbetsplatsen?: En enkätundersökning om logistikkostnader i produktion2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Logistics planning for a construction site is usually limited by traffic flow to and from the workplace. The geographical location of the construction site is determined by roads around the workplace and opportunities for well-functioning logistics. Inventory of material is often impossible because of the frequently small workspaces. As a result, a concern relating material handling remains . Even before the establishment of a construction site, it is required in the construction industry to eliminate errors that might arise in the planning stage. The aim of this study was to contribute with better understanding of the relationship between well-planned logistics and reduced costs at the Swedish construction company Peab. To clarify this a survey was submitted at two construction sites and a sample of calculations were performed on reduced / additional costs at examples of "good" and "bad" planning of logistics, to show how to reduce costs.

    Higher requirements are placed on construction firms and demand such as shorter project times and lower costs and this is supposed to lead to a high profitability. To increase the profitability it is required that the construction industry is planning the amount of resources, manpower, material and time in the absolutely best way. Logistics is a part of the construction industry which may help reduce costs and provide greater profitability, if it is seen as a saving and not just a cost. There should, in other words, be a greater emphasis on planning of the logistics already at early stages of projects.

    There is a great amount of work on purchase of materials in the company Peab in the current situation, but if the company also put equal work on logistics, the planning could be optimized even before the project starts. Through good planning Peab will not only save on cost of purchase, but may also contribute to a better handling of material. Better handling of material also contributes to reduced costs for the project. Material is not only bound capital but can also disappear in waste, thievery or even destroyed. This is also appreciated by both professional workers and employees in the workplace. The opportunities for improvement and efficiency of logistics at Peab are great. By selecting a logistics manager at each construction project and also having a specialist in charge of the region that serves as support for the projects, Peab can save on logistics. The purpose of this report is to look at changing the view of logistics today on construction sites. The result of the calculation examples and survey shows where the largest cost items located in the various projects and how to achieve lower costs through better planning. This in turn helps the company increase profitability in the long term.

    Intern kontroll: Används visselblåsning som mekanism i den interna kontrollenmot oegentligheter av ekonomisk brottslighet inom kreditinstituten?2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study is to examine the banks view of internalcontrol and further investigate what mechanisms are used tostreamline the internal controls. The study is directed into whetherthe whistle-blowing is used as one of the tools in the internalcontrol to enhance the ability to detect and prevent irregularities ofa financial character.

    The study use a inductive method to lead the collection of datamaterial. The study further use a qualitative method based on fourinterviews with different banks were this data material is comparedwith existing theories in the second chapter.

    The study shows that the view of internal control and whistleblowingis positive in the process to create a successful company inthe banks. Despite that the whistle- blowing is known as acomplicated function, it’s still used to detect and preventirregularities of crimes, such of financial character. Except whistleblowing,the banks are using more tools to streamline the internalcontrol. To urge employees to comply laws and other principles,education in different areas for employers but also to createdifferent work approaches in the company, to make internal checkupsand constant supervision of the organization work is some ofthe tools that are used.

    Abstract [en]

    The purpose of this thesis is to create a deeper and also a better understanding about how each of the professional secrecy and obligation to report are perceived from auditors and further investigate how the potential conflicts based on independence and “can be suspect” are handled by the auditors. The purpose has been achieved through interviews with four different accounting firms.

    The interviews were conducted with Grant Thornton, BDO Mälardalen AB, PwC and KPMG to answer the research questions. Subsequently, a hermeneutic approach was used to since the interpretation of the interviews was considered as important to obtain knowledge of the respondent’s perception about the topic. In the analyze chapter have dataset from the reference framework and empirical part been used to implement the analyze of the thesis.

    The study shows that the professional secrecy is important for creating a good relationship with clients and is not considered as a rule that create conflicts for auditors. The obligation to report, however, is creating conflicts because of the lack of knowledge in assessment of economic crimes. The auditors therefore decide to investigate a situation that “can be suspect” beyond what is intended. To not become dependent on the clients, there are rules and profession practices that are used and also examples like not having friends or family members as clients.

    Bokföringsbrott: Ett resultat av oaktsamhet i bokföring?2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Datum: 29 maj, 2013

    Nivå: Kandidatuppsats i företagsekonomi, 15 hp

    Institution: Akademin för ekonomi, samhälle och teknik, ESTMälardalens Högskola

    Författare: Lezan Abdlwafa, Anita Balci & Awat Safari

    Titel: Bokföringsbrott – Ett resultat av oaktsamhet i bokföring?

    Handledare: Ulla Pettersson

    Nyckelord: Bokföringsbrott, oaktsamhet, bokföringsskyldighet, god redovisningssed, Ekobrottsmyndigheten, Skatteverket, konkursförvaltare

    Frågeställning: På vilket sätt leder näringsidkarens oaktsamhet i bokföring till bokföringsbrott? Vilka faktorer bidrar till detta?

    Syfte: Att undersöka hur näringsidkarens oaktsamhet i bokföringen kan vara en av orsakerna till bokföringsbrott.

    Metod: För att uppnå syftet så använde vi oss av en kvalitativ metod för att få en djupare förståelse av ämnet. Vi inhämtade vårt material till referensramen från litteratur samt lagar såsom bokföringslagen, årsredovisningslagen och brottsbalken. Material till empirin var hämtad från tre intervjuer med personer som besitter relevant kunskap, en skattebrottsutredare, en konkursförvaltare och en åklagare.

    Slutsats: Det vi har kommit fram till i vår uppsats är att oaktsamhet i bokföring är en orsak till bokföringsbrott, främst i mindre företag som inte har resurser till att upprätta bokföring på ett sätt som ger en rättvisande bild av företagets ekonomiska ställning.

    Nitrous Oxide Production from Soils Amended with Biogas Residues and Cattle Slurry2013In: Journal of Environmental Quality, ISSN 0047-2425, E-ISSN 1537-2537, Vol. 42, no 4, p. 1046-1058Article in journal (Refereed)
    Abstract [en]

    The amount of residues generated from biogas production has increased dramatically due to the worldwide interest in renewable energy. A common way to handle the residues is to use them as fertilizers in crop production. Application of biogas residues to agricultural soils may be accompanied with environmental risks, such as increased N2O emission. In 24-d laboratory experiments, N2O dynamics and total production were studied in arable soils (sandy, clay, and organic) amended with one of two types of anaerobically digested biogas residues (BR-A and BR-B) generated from urban and agricultural waste and nondigested cattle slurry (CS) applied at rates corresponding to 70 kg NH4+-N ha(-1). Total N2O-N losses from the sandy soil were higher after amendment with BR-B (0.32 g N2O-N m(-2)) than BR-A or CS (0.02 and 0.18 g N2O-N m(-2), respectively). In the clay soil, N2O-N losses were very low for CS (0.02 g N2O-N m(-2)) but higher for BR-A and BR-B (0.25 and 0.15 g N2O-N m(-2), respectively). In the organic soil, CS gave higher total N2O-N losses (0.31 g N2O-N m(-2)) than BR-A or BR-B (0.09 and 0.08 g N2O-N m(-2), respectively). Emission peaks differed considerably between soils, occurring on Day 1 in the organic soil and on Days 11 to 15 in the sand, whereas in the clay the peak varied markedly (Days 1, 6, and 13) depending on residue type. In all treatments, NH4+ concentration decreased with time, and NO3- concentration increased. Potential ammonium oxidation and potential denitrification activity increased significantly in the amended sandy soil but not in the organic soil and only in the clay amended with CS. The results showed that fertilization with BR can increase N2O emissions and that the size is dependent on the total N and organic C content of the slurry and on soil type. In conclusion, the two types of BR and the CS are not interchangeable regarding their effects on N2O production in different soils, and, hence, matching fertilizer type to soil type could reduce N2O emissions. For instance, it could be advisable to avoid fertilization of organic soils with CS containing high amounts or organic C and instead use BR. In clay soil, however, the risk of N2O emissions could be lowered by choosing a CS.

    Värdeerbjudande i fysisk butik jämfört med den digitala handeln: En studie om hur värdeerbjudandet upplevs av kunderna i syfte att kunna skapa bättre samverkan mellan fysisk och digitala försäljningskanaler2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detaljhandeln står inför ett stort skifte för att kunna tillgodose alla de nya krav som kunderna sätter på företagen. Företag och organisationer behöver hantera digitaliseringen som sker och förändrar deras marknad otroligt snabbt. Denna studie har för avsikt att skapa underlag för en innovativ affärsmodell. Denna modell ska bidra till att hjälpa organisationer, att skapa en bild för hur organisationer behöver använda tid och resurser till att kunna vara relevanta men också utvecklas i och med den förändrande marknaden. Fokus i studien ligger på vilket sorts värde kunderna erbjuds samt hur fysisk och digital handel kan samverka. I samarbete med Lindex, en väldigt stor aktör inom detaljhandeln, med sitt fokus på kläder för kvinnor och barn. En induktiv forskningsmetod med kvalitativa intervjuer som grund användes för att samla in data. I och med dessa intervjuer kunde åsikter och tankar från medlemmar inom organisationen, samt kunder med perspektiv från utifrån fångas upp för att skapa en heltäckande bild hur organisationen ser ut och uppfattades.Det som studien visade var att värdeerbjudandet skiljer sig i den fysiska och digitala handeln men de visade även att erbjudandet i de olika kanalerna bör inte vara densamma. Utan istället skapa en mer personlig upplevelse för kunden. Som hjälper kunden vare sig de väljer att handla online eller i fysisk butik.I studien framgår det även hur den individuella servicen som personalen kan ge genom rekommendationer och inspiration utifrån kundens tidigare köp. Det tillsammans med vad som är de nya trenderna för tillfället för att kunna ge ett mer helhetserbjudande med individualitet till deras kunder.Med hjälp av studiens handledare Handledare Erik Lindhult.

    Multi-project Management in an Internal Development Context: A case study focused on identifying challenges in project portfolio management at ABB Components2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis was to explore what challenges are identified in project portfolio management (PPM) in an internal multi-project environment. The aim of this study was to find the underlying reason for the occurrence of challenges in terms of how these challenges occur, and why do they occur. To realize the purpose and the aim of the study, the research was conducted at ABB Components, a business unit of ABB Group. Further, based on identified challenges provide a set of guidelines and recommendations for managing and countering the challenges.

    To understand the research problem a literature review was employed and a case study was conducted at ABB Components. The purpose of the literature review was to gain a theoretical background related to the research topic, identify challenges or problems, and potential solutions, with the purpose of establishing a connection to the challenges identified in the case study. The empirical work consisted of the case study conducted at ABB Components and was constituted by interviews person. The analysis of the results was validated with a workshop held with interviewees, with discussions regarding the findings. Guidelines and recommendations for managing challenges related to project portfolio management were designed from the results of empirical and theoretical work.

    The 11 main challenges related to project portfolio management were identified throughout three defined project phases, initiation of a project, execution of a project and project closure, and was appearing either in one phase or across phases. The challenges in this research were correlated to four main causes; limited resources (budget & time), limited resources (personnel), vague directives, and project maturity. The identified challenges can be encountered and managed by utilizing existing models for project management, improved information handling, expanding the notion of criteria for project success, performing a resource capacity analysis, and planning for the project closure.

    The theoretical and practical work have contributed to a collective analysis of what types of challenges are evident in phases throughout a single project, and what outcomes these challenges can have on a project portfolio in an internal multi-project environment and . It has to some extent indicated differences among challenges and causes evident in multi-project settings, for projects that are classified as internal development or product development, implicating differences throughout the project phase. Furthermore the challenges have pivoted around the three main themes centered indicating that there are challenges related to each phase of the project life, as well as challenges which are apparent across the project phases.

    Title: Accounting and money laundering, a study on how auditors apply the law on money laundering

    Date:  May 29th 2013

    University: Mälardalens University

    Institution: School of economy, society and technology

    Level: Bachelor thesis in business economy, 15 credits

    Authors: Pavle Adasevic 910731 Oskar Hallberg 900508

    Advisor: Kent Trosander

    Keywords: Money laundering, Law of money laundering, Auditor, ABL

    The main issue:In 2009 a new law on money laundering was introduced. The new law aims to strengthen the monitoring and reporting of money laundering. In 2011 11,464 reported suspicions of money laundering, only four of them where from audits, how come there so few reports from the auditors?

    Purpose: The Purpose of the study is to show how audits apply the new money laundering law in their work.

    Method: The study was based upon qualitative method. Secondary data was taken from literature, articles and reports. Primary data are interviews with three respondents, two auditors and one person from the financial police.

    Conclusion: The study shows that auditors apply the law in their work. Although the Money Laundering law can be regarded as clear and applicable thou the design however can be discussable. A hypothesis of a new concept that has been discovered from the study is companysmurfing.

    Knowledge integration in a multinational setting: a study of a transnational business project2009In: International Journal of Knowledge Management Studies, ISSN 1743-8268, E-ISSN 1743-8276, Vol. 3, no 3-4, p. 295-312Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to study how communication enables knowledge integration within transnational projects. Using longitudinal case study data to explore the theoretical arguments, interesting findings emerge. The main finding is that knowledge integration within the transnational project was hampered by ignorance – among project managers and members – of the impact and link between the use of different communication tools, subsequent communication process and knowledge integration. Other findings relate to how institutionalised behaviour persist change and subsequently partly explained why the communication process and thereto related communication tools were not adjusted to new circumstances and conditions. Finally, communication is an inherent part of knowledge integration within a transnational project and there is a need for communication to be sensitive to the complexity of the knowledge being integrated.

    Vidhäftning mellan prefabelement och pågjutningsbetong: Undersökning hur skrovligheten påverkar vidhäftningskapaciteten vid skjuvning2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Self-compacting concrete has soon been around for a decade. Recently the prefabrication industry has started to use this fairly new concrete type in larger scales, mainly because of its distinctive properties.  There are still certain areas that need to be thoroughly examined, such as bond capacity. There have been very few studies regarding shear capacity due to the fact that the procedure is complicated.

    This report will highlight a method to examine the shear capacity of different surfaces that have been prewetted as well as non-prewetted surfaces. The surface areas follow BBK 04’s and Eurocode 2’s demand for surface roughness.  A smooth surface will be completed in order to confirm if the different shapes influence the bond strength by shear stress or not.                       

    The purpose of this essay is to measure the bond strength within the shear capacity as well as examine the impact it has on surface roughness and treatment for shear bond.

    The method used to identify the shear capacity is called L-shaped Push-Off Test. The dimension of the object was selected with the help of a previous research paper. The Sand-Patch method is predominantly used to measure the surface roughness. 

    The results showed no difference between the demands of surfaces of BBK04 and Eurocode 2 considering the shear capacity. However the non-prewetted surface was measured with the highest shear capacity value. Apart from the shear strength, deformation was measured in both vertical and horizontal direction and it was clearly shown that the vertical deformation was measured to be ten times higher than the horizontal deformation.  There was no difference between the BBK 04 and Eurocode 2 considering the vertical deformation. However the difference occurred on the horizontal direction between BBK 04 and Eurocode 2 where the specimens of Eurocode 2 received three times higher deformation compared to BBK 04. The conclusion can be drawn that the surface roughness of BBK 04 would be more suitable than eurocode2 considering deformation.     

    The overall result was that the surface treatment with the demands of BBK 04 and Eurocode 2 showed minor difference after being measured with the Push-Off Test method. This has been confirmed with the estimated shear capacity (1.2 MPa). The results revealed that the treatment of surface could be made in either way, brush or rake. As a conclusion the assessment of the shear strength showed that Eurocode 2's demand is too strict comparing demands of BBK 04.

    Projektledarens färdväg mot kompetensutveckling: En analys av projektledarkompetens och planeringsverktyg hos JM AB2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A project manager's responsibility in a project is to lead the project to specified goals with defined specifications. These goals must be achieved within a time related and economic framework. To achieve these goals, a project manager needs to early plan and implement a financial plan for the project. If the project manager lacks sufficient competence it may result in financial losses and failed project.  The present thesis was accomplished in collaboration with the construction company, JM AB, and the study consists of three parts. An extensive literature review has been conducted in which the theoretical perspective around the project have been analyzed. Interviews with project managers and site visits were conducted in order to achieve a deeper understanding of how JM works with timetables and existing competency development plans. The study shows that the project manager at JM AB is primarily involved in the early stages and the final stage of the project planning. Furthermore, this thesis showed that the project manager's skills development first of all takes place in daily work. In addition, the results showed that experience from previous work constitutes the most important skills development for the project managers and that activities such as formal courses also a contribute to stronger competence for the project manager.

    A Machine Learning Approach for Biomass Characterization2019In: INNOVATIVE SOLUTIONS FOR ENERGY TRANSITIONS / [ed] Yan, J Yang, HX Li, H Chen, X, ELSEVIER SCIENCE BV , 2019, p. 1279-1287Conference paper (Refereed)
    Abstract [en]

    The aim of this work is to apply and evaluate different chemometric approaches employing several machine learning techniques in order to characterize the moisture content in biomass from data obtained by Near Infrared (NIR) spectroscopy. The approaches include three main parts: a) data pre-processing, b) wavelength selection and c) development of a regression model enabling moisture content measurement. Standard Normal Variate (SNV), Multiplicative Scatter Correction and Savitzky-Golay first (SGi) and second (SG2) derivatives and its combinations were applied for data pre-processing. Genetic algorithm (GA) and iterative PLS (iPLS) were used for wavelength selection. Artificial Neural Network (ANN), Gaussian Process Regression (GPR), Support Vector Regression (SVR) and traditional Partial Least Squares (PLS) regression, were employed as machine learning regression methods. Results shows that SNV combined with SG1 first derivative performs the best in data pre-processing. The GA is the most effective methods for variable selection and GPR achieved a high accuracy in regression modeling while having low demands on computation time. Overall, the machine learning techniques demonstrate a great potential to be used in future NIR spectroscopy applications.

    Kompetensutveckling i projektledning: En kompetensutvecklingshandbok för projektingenjörer2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis presents a study of competence and knowledge needs of project engineers to be able to manage projects successfully. The aim of the thesis is to identify how to feedback competences and experiences into the project management process. The guidebook provides guidance to what a project engineer needs to focus on to become more skilled and to become a more effective project manager.

    A literature study was performed to get a better understanding of the project manager's role. A detailed study was performed on the duties of project engineers and project managers. The literature study was based on books and reports as well as an information research by the Internet. An interview with five project managers and five project engineers was conducted to compare theory with practice. Based on the respondents' answers and the results from the literature study a handbook outlining what the project engineer can do to improve their project management skills.

    The thesis concludes that competence development depends on individual motivation. Every individual have their own goals and they are stimulated by different motivational factors. Some aims high to become CEO for a company, while other are satisfied with their positions and it doesn’t mean that all project engineer / project manager strives for continuous development.

    The main question of the thesis was: "What skills are needed for project engineers to develop their skills in project management?”. The results of the thesis show that without learning from their mistakes and problems that were made in previous project and by making their own mistakes the project engineer will not develop or become a more efficient project manager. By learning from experiences from previous projects the project engineer can save significant time when facing similar problems in new projects. Recording and using this knowledge may contribute to more effective solutions and thus reducing time lost unnecessarily.

    Simulation of Indoor Radon and Energy Recovery Ventilation Systems in Residential Buildings2015Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This study aims to investigate the effects of ventilation rate, indoor air temperature, humidity and using a heat recovery ventilation system on indoor radon concentration and distribution.

    Methods employed include energy dynamic and computational fluid dynamics simulation, experimental measurement and analytical investigations. Experimental investigations primarily utilize a continuous radon meter and a detached house equipped with a recovery heat exchanger unit.

    The results of the dynamic simulation show that the heat recovery unit is cost-effective for the cold Swedish climate and an energy saving of about 30 kWh per  floor area per year is possible, while it can be also used to lower radon level.

    The numerical results showed that ventilation rate and ventilation location have significant impacts on both radon content and distribution, whereas indoor air temperature only has a small effect on radon level and distribution and humidity has no impact on radon level but has a small impact on its distribution.

    Simulation of ventilation effects on indoor radon2013In: Management of environmental quality, ISSN 1477-7835, E-ISSN 1758-6119, Vol. 24, no 3, p. 394-407Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to describe the use of computational fluid dynamics (CFD) to simulate indoor radon distribution and ventilation effects. This technique was used to predict and visualize radon content and indoor air quality in a one-family detached house in Stockholm. The effects of intake fans, exhaust fans and doors on radon concentration were investigated. Design/methodology/approach: In this study a mechanically balanced ventilation system and a continuous radon monitor (CRM) were used to measure the indoor ventilation rate and radon levels. In a numerical approach, the FLUENT CFD package was used to simulate radon entry into the building and ventilation effects. Findings: Results of the numerical study indicated that indoor pressure created by ventilation systems and infiltration through doors or windows have significant effects on indoor radon content. The location of vents was found to affect the indoor radon level and distribution. Research limitations/implications: It may be possible to improve any discrepancies found in this article by using a more refined representation of grids and certain boundary conditions, such as pressure and temperature differences between inside and outside and by considering some real situations in residential buildings and external situations. Originality/value: From the viewpoints of indoor air quality (IAQ) and energy savings, ventilation has two opposing functions; on the positive side it enhances IAQ and the establishment of thermal comfort, and on the negative side it increases energy consumption. This paper describes the search for a solution to cope with this contradiction.

    Simulation of ventilation effects on indoor radon in a detached house2012In: WSEAS Transactions on Fluid Mechanics, ISSN 1790-5087, Vol. 7, no 4, p. 146-155Article in journal (Refereed)
    Abstract [en]

    CFD is widely used in indoor air quality, air flow pattern, indoor pollutant distribution and thermal comfort as a cost effective and powerful tool and it can be used to predict, estimate and visualize the indoor radon level. The intention of this article is to use computational fluid dynamics (CFD), as a standalone tool to simulate indoor radon distribution and ventilation effects. This technique can be used to predict and visualize radon content and indoor air quality throughout a one family detached house in Stockholm. In this study a mechanical balanced ventilation system and a continuous radon monitor (CRM) were also used to measure the indoor ventilation rate and radon levels. In numerical approach the FLUENT, CFD package was used to simulate radon entry into the building and ventilation effects. Results of numerical study indicated that indoor pressure made by means of ventilation systems and infiltration through door or window has significant effects on indoor radon content. It is observed that the location of vents can affect the indoor radon level, particularly in breathing (seating) zone. The analytic solution is used to validate numeric results at 3 distinct air change rates. The comparison amongst analytical, numerical and measurement results shows close agreement.

    Impacts of heat recovery ventilators on energy savings and indoor radon level2013In: Management of environmental quality, ISSN 1477-7835, E-ISSN 1758-6119, Vol. 24, no 5, p. 682-694Article in journal (Refereed)
    Abstract [en]

    Purpose: This paper aims to investigate the impact of heat recovery ventilators (HRVs) on the energy use and indoor radon in a one family detached house. Heat recovery ventilation systems, because of reducing ventilation loss through recovered exhaust air, can play a good role in the effectiveness of ventilation to reduce energy use. In addition HRVs can maintain pressure balance and outdoor ventilation rate at a required level to mitigate indoor radon level. Design/methodology/approach: In this study, a multizone model of a detached house is developed in IDA Indoor Climate and Energy (IDA ICE 4.0). The model is validated using measurements regarding use of energy for heating, ventilation and whole energy use. The performance of the heat recovery ventilation system is examined with respect to radon mitigation and energy saving by measuring the radon concentration and analyzing the life cycle cost of a heat exchanger unit. Findings: The results of the measurements and dynamic simulation showed that the heat recovery ventilation system could lead to 74 per cent energy savings of the ventilation loss, amounting to about 30 kWh m-2 per year. Life cycle cost analysis used for assessing total costs and the result showed that using this system is quite cost-effective and investment would payback during 12 years. Research limitations/implications: Limitations of this study generally refer to radon measurement and simulation because of radon complex behavior and its high fluctuations even during short periods of time. Practical implications: Heat recovery ventilation systems with reducing radon concentration improve indoor air quality and decrease environmental problems with energy savings. Social implications: Using balanced heat recovery ventilation can have benefits from the viewpoint of environmental impacts and household economy. Originality/value: Employment of a heat recovery unit to control indoor radon level is a new usage of this technology which along with energy savings can improve sustainable development.

    Sustainable flue-gas quench: For waste incineration plants within a water-energy-environment nexus perspective2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The function of a flue-gas quench is to remove additional contaminants from flue-gas and to reduce the wastewater from a waste incineration plant. The aim of this degree project is to find how the system is affected by using a quench and what factors limits the performance. This is done by modelling and simulating a waste incineration plant in Aspen Plus. Data and plant schematics were obtained by a study visit to Mälarenergi Plant 6 situated in Västerås, Sweden, which were used as model input and for model validation. The results have shown that the amount of wastewater can be reduced by more than half compared to a plant without a quench. The heat produced in the condenser, when discharging water to the boiler, would be lowered by up to 20%. For systems with a quench present when more water was discharged to the boiler both the heat production and the pollutant capturing became better. However, the system has limits regarding the amount that could be recirculated, in the form of temperature limits in different parts of the system. In addition, if the heat load is low there is an insufficient amount of wastewater generated in the condenser to run the quench. In that situation, clean (fresh) water needs to be used instead. Using clean water is unwanted since the plant will then consume more resources while still producing less heat than a plant without a quench would.

    Abstract [en]

    Progressive collapses may occur when a bearing wall is eliminated for various reasons. It can be a gas explosion or collision accident of a train or a vehicle, but also during renovation of a building component. After the wall has been eliminated, the building should be undamaged and not suffer a progressive collapse. Such an event can be avoided through a vertical link. The purpose of this study is to examine how secure today's vertical strap’sare against progressive collapse, and to find a solution for reduced risk of collapse Method: This study includes a literature review and a case study. The literature review was performed by a deepening of the existing literature that investigated the progressive collapse and the vertical drag strip. The studies found through the database Google school and Discovery. The case study was conducted in Kadesjös which is an engineering office where drawings and calculations were performed. Result: The result indicates that the vertical strap used today cannot withstand the design load if the entire wall (including the screw attachment) is eliminated. The threaded rod will then be pulled out of the floor and a progressive collapse occurs. By mounting a 70x70mm plate in the floor this can be prevented. Without the plate it takes only 58 kN to pull out the threaded rod from the floor, but with the plate the connection’s capacity is increased to 100 kN and then the anchorage pipe limits the capacity. Conclusion: The conclusion of this thesis is that a plate that increases the vertical strap’s capacity and thereby increases the safety against progressive collapse should be used.

    The Univeristy-to-Industry Knowledge Transfer: A micro-analysis of knowledge transfer practices & processes of Mälardalen University2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Literature on knowledge transfer has mainly studied this topic at macro level. The purpose of this research is to explore the university's role in the university-to-industry knowledge transfer on a micro level. This study is focused on the role played by Mälardalen University (MU) in the knowledge transfer to local industry by focusing on the university practices accomplished to this end. The research question is: Through which practices does Mälardalen University take part in the university-to-industry knowledge transfer?

    Methodology/Approach:

    The case study is about MU in Sweden, in Västerås and Eskilstuna campuses. A qualitative study approach was conducted to explore the research question and sub-questions. With the use of semi-structured interviews primary data was collected. Information in the literature review and theoretical framework chapters were collected by drawing from the databases: ‘ABI/inform’ and ‘Google Scholar’.

    Findings/conclusion:

    Based on the data collection, it can be concluded that the learning processes at MU rely on (experiential) ‘work and project-based-learning’ practices. These processes provide students with the knowledge demanded by the industry. The close collaboration between university and industry improves the preparation of students entering the job market in several ways. This research highlights which successful practices may be implemented at university level to promote the knowledge transfer to industry while supporting learning processes, particularly effective for engineering/nursing students. It also provides us with additional findings on the importance of co-creation practices in the development and innovation of knowledge creation.

    Limitations:

    A limitation of this study is the selective focus on one university. Another limitation is that the industrial perspective is excluded. However, such a limitation sheds light on a focus for possible future research.

    ENERGY ASSESMENT FOR MODULARDETACHED BUILDINGS: Case studies, Sweden and Spain.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Energy assessment in buildings is an essential topic in order to achieve the set goals for energy efficiency. This thesis investigated the energy consumption in various scenarios in Husmuttern’s buildings. Different purposes (school and apartment), locations (Spain and Sweden) and materials combinations are modelled and analysed. The models were created in the building performance simulation tool IDA ICE. After the yearly energy demand results were obtained they were processed and analysed. Then several factors were changed in the model in order to investigate different impacts in the energy consumption of the building, such as the overall heat transfer, hot water consumption, windows and doors. Also, PV panels were installed in the model to obtain the potential penetration of renewable energy in the buildings. The results showed the different consumption in the buildings depending on the purpose and location, and the impact of the changed factors in the overall energy consumption. The change of windows to more efficient ones showed that the apartments improve their consumption more than the schools, especially in when the Spanish location is considered. This case also had the biggest possible change when the hot water demand is varied. Whereas if the door was the changed, the Swedish apartment has the most possible improvement.

    Spare parts management potential in production sector2015Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Spare parts management (SPM) is an important branch of management which could lead the company to success or bankruptcy. It is also fill of potential improvements that can increase the company profits, productivity, and reliability. Wise inventory management would eliminate all the delay risks of unplanned breakdowns, and reduce process time and cost. 

    To understand the importance of the spare parts, a fundamental knowledge of maintenance types, spare parts, spare parts management, spare parts classifications, ABC analysis, Economic order quantity, suppliers’ management, purchase management, and management computer program SAP, have been viewed.

    Companies realize the spare parts importance and try to develop the system to increase the benefits. Many ways has been taken to achieve that. Each company has it is own management system that the company has developed in years.

    In this research, spare parts management system of seven companies has been studied. By comparing of the management systems, we highlight the areas that would have negative or positive impact on the system. We would also analysis why the companies have chosen these systems, how they develop the system, and where they aim throw the development.

    Reviewing case studies would have many advantages, it would expand the vision to develop the management system and focus on the points that have permanent value instead of focus on temporary improvement.

    Two check lists of points that could have potential improvement, have been presented and in which improvement type.

    Method: This research was conducted by a quantitative research method. Attitudes were measured through an online survey where a convenience sample was applied by sharing the survey on Facebook. The answers were analysed in SPSS, where frequencies and central tendencies were identified and compared.

    Conclusion: Individuals have more positive attitudes towards information sharing when using recruitment services driven by AI, then they have to general information sharing online. Attitudes differ depending on the socioeconomic factors, level of education and level of occupation. Individuals with a high level of education and those with a high qualification level of occupation have more positive attitudes than those with low level of education and low qualification level of occupation. Income level have no impact on the attitude components. For companies that offer recruitment services driven by AI, it is best to target the ones with a high level of education and a high occupational qualification level, since they are the ones most likely to use the service.

    Skapandet av förtroende i en kundrelation för nystartade företag i bemanningsbranschen: En kvalitativ studie om hur förtroende skapas mellan nystartade företag och kunder i bemanningsbranschen2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den höga konkurrensen på marknaden har bidragit till att nystartade bemanningsföretag upplever en svårighet i att skapa en stark och långvarig relation till sina potentiella kunder. Detta har medfört till att de flesta företag har börjat lägga mer vikt på mötet med kunden för att uppfylla kundens behov och därmed skapa ett förtroende. Studiens syfte är att utifrån ett företagsperspektiv undersöka hur nystartade företag inom bemanningsbranschen arbetar med förtroende i sina kundrelationer. Vidare ämnar studien att undersöka vilket arbetssätt som har störst påverkan på skapandet av förtroende i en relation till kunden. Undersökningen baseras på en kvalitativ metod där semistrukturerade intervjuer genomfördes med sex olika företag. Studien visade att de nystartade företagen arbetar oerhört snarlikt med de teorierna som valdes ut för att skapa ett förtroende. Däremot resulterade studien i en förståelse angående att kommunikation var det som företagen främst arbetar med för att skapa förtroende, både personlig (direkt) och digital kommunikation. Under studiens gång upptäcktes faktorer som skapar förtroende utöver de som valdes i teoriavsnittet som har tillkommit. Det har visat sig att hålla löften och att besitta goda referenser är av betydande vikt för nystartade företag när de vill bygga upp förtroende i sina kundrelationer.

    Viktiga kriterier vid val av leverantörer inom stålindustrin2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Stålindustrin har en stor påverkan för utvecklingen av samhället. Studier visar att stålindustrins betydelse kommer fortsätta att växa sig större inför framtiden (Mooney, 2016). Val av leverantör är en av de viktigaste delarna i inköpsprocessen då leverantörer spelar stor roll i ett företags prestation. (Vokurka, Choobineh & Vadi, 1996; Luzzini, Caniato & Spina, 2014) Att identifiera viktiga kriterier vid val av leverantörer kan vara komplext. Detta är ett stort forskningsområde och antalet studier inom detta ämne är otaliga. Dock finns det färre studier som riktar in sig på specifikt leverantörer inom stålindustrin. Av denna anledning valde vi att undersöka vilka kriterier som är viktiga vid val av leverantörer inom just stålindustrin för att kunna stödja redan existerande studier eller bidra med nya kunskapar för ämnesområdet. Sammanfattningsvis var syftet av vår studie att undersöka vilka kriterier som är viktiga vid val av leverantörer inom ståltillverkning och hur dessa kriterier ska viktas.

    Denna studie undersökte leverantörskriterier utifrån en kombination av en fallstudie på företaget ABB och redan existerande forskning. Utifrån detta, har de viktigaste kriterierna identifierats för leverantörer inom stålindustrin. Inom både litteraturstudien och empirin rangordnades kvalitet, leverans och pris som de tre viktigaste kriterierna. Efterföljande kriterier, i rangordningen, var service, R&D, finansiell styrka och geografisk position. Dessa kriterier har sedan applicerats i en numerisk analysmetod, analytical hierarchy process (AHP), där viktade värden för kriterierna räknades ut. Resultatet av denna viktning blev: kvalitet = 36%, leverans = 25%, pris = 17%, service = 11%, R&D = 5%, finansiell styrka = 4% och geografisk position = 2%. Resultatet av viktningen för varje leverantörskriterium påvisade en del skillnader från tidigare forskning, men även många likheter.

    För att nå resultatet i denna studie har en kombination av kvalitativa och kvantitativa metoder applicerats, i form av intervjuer, enkätstudie och observationer.

    Research question: Does the audit fee size effect an auditor’s tendency to submit an unqualified or qualified audit report, if is so, how?

    Purpose: The purpose of this study is to extend previous research conducted on this topic by examining whether an auditor’s tendency to give an unqualified or qualified audit report is affected by the audit fee size, if is so, how?

    Method: The study is based on a quantitative method in which the primary data is taken from the database Retriever and comprises 300 annual reports from the year 2009, which belong to Vastmanland´s micro- company financial statement. The study also applied a deductive approach, which meant that secondary data in the shape of established theories and also previous research on the subject was the basis for the creation of the study´s hypotheses. After the collection of primary data, the data was compiled in Microsoft Excel and then the data was analyzed using bivariate- and multivariate logistic regression analysis in SPSS.

    Conclusion: In the bivariate logistic regression analysis we found that there is no significant relation between the size of the audit fee and an auditor's tendency to give an unqualified or qualified audit report. On the other hand a positive significant relationship between these variables was found in the multivariate logistic regression analysis. The results of the multivariate logistic regression analysis can be interpreted that as a higher audit fee provides a greater probability that an auditor issues a qualified audit report. The study also shows that extensive efforts and lack of financial resources in the form of internal control may be associated with an auditor submits a qualified audit report and receives high audit fee.

    An integration of the Technology Acceptance Model in the effectiveness of Word-of-Mouth on the Online Purchase Intention.2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to examine the impact of both forms of Word-Of-Mouth (WOM), the electronic (eWOM), and the personal (pWOM) on the online purchase intention. This interaction was tested by the main components of the Technology Acceptance Model, the perceived usefulness, and the perceived ease-of-use with the adoption of a symbolic usage of an innovative product, the smartwatches.

    Three sets of hypotheses were formulated in order to investigate the impact of word of mouth on the online purchase intention. For the purpose of this study, a quantitative research method was selected, and the data was collected by an online questionnaire distributed to Swedish consumers. A data set of 241 Swedish respondents was collected and taken for analysis. A simple and a multiple regression analysis through the IBM SPSS Statistics was used to test the hypotheses. Also, the mediating effect was investigated with the Sobel test.

    Findings indicated that the forms of WOM have a different impact on the online purchase intention for the Swedish consumers. Personal WOM was rejected by the respondents as an exogenous factor that could influence them to accept an innovative product and purchase it online. On the other hand, electronic WOM is positively and significantly related with both the perceived usefulness and the perceived ease-of-use. Moreover, the hypotheses about the TAM and the online purchase intention were supported.

    Abstract [en]

    A construction project can be compared to a triathlon where the building process takes place in three stages and participants try to finish three sub processes as fast as possible to reach the goal. After the first stage is finished, the next begins to eventually jointly meet the milestones that are set on the road. There are many different players in a building process where everyone can have completely different tasks and work in completely different locations around the world. This require that the information between the different parties must be correct and shared to avoid delays and unnecessary costs.

    Identifying, defining and structuring of information in the 3D-model reflects an organized approach where all information is available in the same location. The development in the construction industry has given the opportunity to let the information supply to be almost unlimited. BIM stands for Building Information Modeling, in design/construction models there is room for the construction industry to improve the efficiency and quality at much higher altitudes. Two systems that have grown during the BIM development is the BIP (Building Information Properties) and BSAB 2.0 (Bygg Samordning AB 2.0) which is designation and classification system in Sweden that aims to become the solution for a joint system for all construction companies. This would lead to that, information delivery becomes waterproof.

     This report is a study of how a common system can be applied to the accounting of the various construction companies to be similar and flawless. The lineup of solutions in the examination are solutions for the modeling software Tekla Structures. There is also an investigation of how the mapping of a complete system that allows the different parties in the construction process to use the same terms throughout the different sub processes.

    Abstract [en]

    The purpose of this degree project is to investigate noise problems for residential areas close to roads with very intense traffic. The area Lilla Essingen in Stockholm has been investigated and most focus is on noise measurements outdoors and different measures for noise reduction in the area. Sound measurements are the basis for this work, but calculations have been made to obtain the 24-hour equivalent sound level and maximum sound level for the different measurement points. Interviews are also an important part of this work, where the sales market for apartments located closest to the road is discussed with various brokers from different companies in the area. Furthermore, the harmful health effects that are obtained due to high noise levels, various measures for reducing noise impact and the different measured values ​​at different times during the day are discussed. The own measured and recalculated 24-hour equivalent noise levels from Lilla Essingen are compared with guideline values from both WHO and Stockholm City in order to better understand the importance of the actual noise within this residential area. Sleep disorders, reduced concentration, stress and hearing damage are the most common effects caused by noise and research has shown that noise also has a connection with cardiovascular diseases. Children are most affected by noise; it can affect their learning development and lead to less concentration compared to the other children who are not exposed to equally high sound levels. The own measurement values ​​have shown that sound levels differ during different times of the day and with different distances from the road. The sound is at its highest in the morning where traffic flow is high, but according to the measurements it has shown that the sound levels are always high next to the road even during the evening / night.

     

    Keywords: Noise, noise impact, motorway, guide values, equivalent sound level, maximum sound level, noise reduction, traffic, quiet side
