    Förebyggande strategier: Socialsekreterares och arbetsledares perspektiv på hur hot och våld hanteras inom socialtjänsten2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study was to investigate how our selected municipalityaddressed theirpreventive work regarding threat and violence among social workers, what strategies social workers have to overcome intimidating situations, and also what level of education social workers have. Previous research shows that education for social workers inthis topicoften is neglected. The study was conducted by one focus group interview with social workersall working inchild and familywelfarein our selected municipality. The main result of the study is that social workers experience that the municipalitysinternal agenda against threat and violence works well and gives support in their work. Despite this,the social workers expressed a desire to get morerelevant education about threats and violence to be able toavoid risk-taking behavior and be able to perform a more secure job. According to the social workers some of the strategies that affected the safety in their profession was the possibilityto have a direct and clear communication with the client to try and make the meeting between client and social workers more relaxed.

    Experimental study of an intermittent ventilation system in high occupancy spaces2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. Alternative strategies that incorporate elevated air speeds can reduce cooling energy demand and provide occupant’s comfort and productivity at higher operative temperatures. A ventilation strategy, Intermittent Air Jet Strategy (IAJS), which optimizes controlled intermittent airflow and creates non-uniform airflow and non-isothermal conditions, critical for sedentary operations at elevated temperatures, is proposed herein.

    The primary aim of the work was to investigate the potential of IAJS as a ventilation system in high occupancy spaces. Ventilation parameters such as air distribution, thermal comfort and indoor air quality are evaluated and the system is compared with a traditional system, specifically, mixing ventilation (MV). A 3-part research process was used: (1) Technical (objective) evaluation of IAJS in-comparison to MV and displacement ventilation (DV) systems. (2) An occupant response study to IAJS. (3) Estimation of the cooling effect under IAJS and its implications on energy use. All studies were conducted in controlled chambers.

    The results show that while MV and DV creates steady airflow conditions, IAJS has  cyclic airflow profiles which results in a sinusoidal temperature profile around occupants. Air distribution capability of IAJS is similar to MV, both having a generic local air quality index in the occupied zone. On the other hand, the systems overall air change rate was higher than a MV. Thermal comfort results suggest that IAJS generates comfortable thermal climate at higher operative temperatures compared to MV. Occupant responses to IAJS show an improved thermal sensation, air quality perception and acceptability of indoor environment at higher temperatures as compared to MV. A comparative study to estimate the cooling effect of IAJS shows that upper HVAC setpoint can be increased from 2.3 – 4.5 oC for a neutral thermal sensation compared to a MV. This implies a substantial energy saving potential on the ventilation system. In general, IAJS showed a potential for use as a ventilation system in classrooms while promising energy savings.

    Honour Culture: The thoughts and experiences of four young men, who have lived in a residential care home for unaccompanied children2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a qualitative study that explores the thoughts and experiences of honour culture of young men who have previously been living in a residential care home for unaccompanied children. The data was collected through four semi-structured face-to-face interviews. The social constructionist theory was used together with previous research in order to analyse the results. The results of this study show that the informants highly associate honour culture with women, and therefore feel burdened with the fact that they are expected to guard females both in and outside their own families. Results also show that males are subjected to honour based oppression in different forms. Furthermore, it was found that honour culture is connected to shame and a fear of being ostracized from the family or the community.

    Artificiell intelligens som beslutsmetod2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete behandlar artificiell intelligens som beslutsmetod. Efter inledande diskussioner om de övergripande skillnaderna mellan hjärnans och datorns funktionssätt, olika utvecklingsinriktningar av artificiell intelligens samt olika metoder för att skapa artificiell intelligens identifieras strategier för hur artificiell intelligens kan användas som beslutsmetod beroende på faktorer som transparens, effektivitet samt mängden tillgänglig testdata. Exempelvis identifieras några typiska beslutssituationer där det kan antas att automatiserat beslutsfattande baserat på artificiell intelligens har stor potential, samt situationer då metoden kan antas vara mindre lämplig. Därefter analyseras teknikutvecklingen inom artificiell intelligens, både generellt och inom fyra specifika tillämpningsområden: inom autonoma fordon, inom finans, inom medicin och inom militären. Både den övergripande undersökningen av den generella teknikutvecklingen och studien av de fyra teknikområdena indikerar fortsatt mycket snabb utveckling inom området. Exempelvis visar en analys av patentdatabasen Espacenet att antalet patent inom området utvecklas i det närmaste exponentiellt. Samtidigt har det på senare tid gjorts flera tekniska genombrott, t.ex. utvecklandet av allt effektivare algoritmer genom användandet av hierarkiska strukturer med flera olika nivåer av ickelinjär informationsbearbetning, något som ofta benämns Deep Learning. Ett exempel är den metod för artificiell intelligens som utvecklas av DeepMind, som visat sig vara tillämpningsbar inom många olika områden, från att spela klassiska datorspel som Space Invaders och Breakout på en övermänsklig nivå till att göra betydande effektiviseringar i driften av Googles datorhallar. Även ur ett hårdvaruperspektiv är utvecklingen närmast exponentiell, driven av kontinuerliga framsteg inom tillverkningsprocesser samtidigt som det nyligen gjorts betydande framsteg med specialiserade kretsar för artificiell intelligens, något som sannolikt kommer att resultera i ännu snabbare utveckling av kraftfullare artificiell intelligens inom en nära framtid. Med hänsyn till teknikens effektivitet och den mycket snabba utvecklingen inom området diskuteras även några specifika frågeställningar som ofta nämns i diskussionen om artificiell intelligens, dess påverkan på arbetsmarknaden och den globala säkerhetsbalansen, för att baserat på detta sedan diskutera artificiell intelligens som beslutsmetod även i ett vidare perspektiv.

    Lyckad trädflytt: Förberedande åtgärder och efterskötsels inverkan på trädets etablering efter flytt2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this report was to put together facts regarding how the measures before and after tree transplanting can affect the establishment of the tree. The report also dealt with the impact that root pruning might have on trees and how regeneration of roots can be promoted. The report answers questions concerning how tree transplanting affects a tree and how tree species, locality and previous measures can influence the effect of a tree transplanting. The reports also answers a question concerning which measures could be performed, before and after tree transplanting, to improve the tree’s establishment in it’s new locality. The last question that this report answers is what impact root pruning has on the tree and how regeneration of fine roots can be favoured. The report is written as a traditional academic report and is based on literature that was collected from scientific articles, books and encyclopedias. A tree loses a large amount, approximately 90 percent, of its root system during the tree transplanting. This causes stress symptoms in the tree. A tree, sown and grown in nature, that has never been root pruned will lose even larger amounts of its root system when it’s transplanted. It’s important to do investigations before tree transplanting. Investigations should be done before tree transplanting to determine what kind of tree, nursery-grown or grown in nature, and what species is about to be transplanted. Both of these aspects may have an influence on how successful the transplanting is. Root pruning can make the root system more compact which reduces root loss during transplanting. Root pruning also increases the amount of fine roots in the root ball which is beneficent during establishment and also reduces water stress. The high amount of root loss causes an imbalance between crown and roots. The crown is often reduced to correct this imbalance and in this report it was proven that a moderate crown reduction is beneficial for the tree. The tree must overcome the stress symptoms to be able to survive and to establish itself. Trees need good vitality to be able to regenerate roots, shoots and branches. Irrigation plays an important part in the establishment and the survival of the tree. Mulch can promote regeneration of fine roots and contribute to an improved establishment. The conclusion of the report is that both preparatory measures and after care has an impact on the establishment and on how successful the transplanting of a tree will be. A correctly executed root pruning and a moderate crown pruning (10 to 30 percentage of the crown) should be carried out. Trees should be transplanted during their dormant season and trees, that are going to be transplanted, should have high vitality. Regeneration of roots is promoted by having good soil moisture, warm soil, even watering and applying mulch.

    Morgondagens stadsträd: Med Gävle som exempel2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Considering urban trees importance for humans in both environmental and health aspects, this study aimed to explore appropriate urban tree species and varieties with a focus on prevention for current and future epidemics. The basis for this study is Gävle. It is of interest to see what suited a little further north in Sweden, zone 4. This literature survey is based on scientific articles, other literary writings and conversations references with industry expertise and these issues have been the focus. * How does the city tree population looks in Gävle today? * How to choose the new urban trees based on current and future disease epidemics? * What park trees and street trees are suitable for planting in Gävle in order to increase diversity? Gävle has previously, like many other municipalities, planted trees prevailing on trends. This has resulted in an over-representation of the tree genera Tilia, Sorbus and Acer. Invasive disease similar to Ash dieback and Dutch elm disease can knock out large parts of the urban tree population caused by monoculture. Diversity is of great importance in this regard. City tree population should not exceed more than 10% of a species, 20% of a family or more than 30% of a family. It has been a two folded guidelines in the selection of urban trees:

    * Get a better understanding of the prevailing conditions in the urban environment and to enhance the experience on which species thrive in these conditions. * Expand the existing tree population by gathering more knowledge and dare to try new and / or untested species. Recommendations of street trees and park trees in both zone 3 and zone 4 are presented in the report. Interestingly, it emerged both species / varieties that occur in nurseries today but also tree species / varieties that have not yet been introduced.

    The energy system of Greece: A Techno-economic and Environmental Approach2017Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The human effort to continuously improve their standard of living in conjunction with the rapid growth of world‟s population, the reckless and the wasteful misuse of energy reserves threaten to lead mankind in an energy deadlock. In an effort to realize the size of the waste of our planet‟s available energy resources, we only need to point out that people have spent the last century stocks of raw materials and energy, which were saved and produced during the lifetime of our planet. The management of the energy systems in a proper and best way is considered to be essential worldwide. In this project the energy system of Greece is studied. The power production systems used in different sectors of life were analyzed. The study emphasized in the electricity production from different sources. Lignite electricity power plants were first introduced in the country followed by the gas power plants and Renewable Energy Sources (RES) installations. The deregulation of electricity market formed the new energy scenery of the country. Electricity grid reinforcements with smart metering and energy storage proved to be necessary in order the RES to be fully penetrated to the national grid, so as Greenhouse Gas (GHG) emissions to be reduced as much as possible. The further expansion of RES could help to cope with the barriers of the country‟s electrification due to singularity of hundred islands that are not yet interconnected to the mainland. Analytical theory methods and numerical skills used to derive the appropriate data and results. Installed capacity of the power sources was verified as well as costs and polluted emissions per unit and type of sources involved. Weaknesses and abnormalities of the electric system were pointed out. Proved gains from the RES use were verified for ensuring the sustainability of the country‟s energy system

    Rutiner för insamling av indata för energisimuleringsmodeller av skolbyggnader i Norra Sverige (Gävle): En studie baserad på litteraturundersökning och analys av simuleringsmodellen av Stigslundsskolan i Gävle2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Energianvändning i befintlig byggnadsstock utgör en stor del av den totala energianvändningen i Sverige. I dagens läge är minskning av energianvändning av hög prioritet. Moderna simuleringsteknologier ger möjlighet till uppskattning av energianvändning i befintliga hus och utveckling av effektiviseringsåtgärder samt till beräkning av energiprestanda av byggnader i projekteringsfas. Korrekta indata och indatakällor avgör osäkerhetsnivå hos modellen. I detta sammanhang är det viktigt att utveckla rutiner för insamling av indata och specificera osäkerhetskällor. Arbetet fokuseras på utveckling av förslag till rutiner för insamling av indata för energisimuleringsmodeller av skolbyggnader i Norra Sverige, identifiering av termograferings roll vid renovering och ombyggnation samt känslighetsanalys vid byggnadssimulering och framställning av källhierarki. Projektet baserades på litteraturanalys och intervjuning av beträdande konstruktörer. Dessutom utreddes mätdata samlade i samband med renovering av Stigslundsskolan i Gävle och utarbetade simuleringsmodellen av den här skolan. Resultatet av denna studie beskriver rutiner för insamling av indata som omfattar byggnadens lokalisering och klimatdata; specifik konstruktionsdata för simulerad byggnad/del av byggnad; inomhustemperatur, luftflöde vid ventilation och infiltration samt interna värmekällor och data om innevånare och HVAC-system. Dessutom identifierades möjliga osäkerhetskällor och åtgärder för att höja noggrannhet hos modell. Källhierarki för indatakällor bestämdes vilket är angeläget vid modellkalibrering.  Termografin av Stiglundsskolan visade att det finns ett antal bristfälliga delar i klimatskallet som ger upphov till värmeförluster, framför allt fönstren, entrépartierna och sockeln. Fönstren och dörrarna behöver bytas och bristande delar av stommen isoleras. Slutsatserna som kan göras utifrån detta projekt är att det bör väljas indata från källor som står överst i källhierarki för att få fram en modell med låg osäkerhetsnivå. I verkigheten vid simulering av skolbyggnader är hög precision sällan ett krav. I regel prioriteras det tid och bekostnad så länge osäkerheten ligger inom bestämda gränser.

    The Influence of Social Media on E-commerce: Fast Fashion Multinational Companies2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aim: The aim of this thesis is to analyse the influence of social media on fast fashion e-commerce multinational businesses and to identify the aims of Corporations using social media and why they adopt it as a marketing strategy to meet their long term objectives.  

    Methodology Approach:  This research study utilised a qualitative approach which comprises of primary and secondary data in order to conduct research and gather empirical evidence to evaluate the research aims and questions and to fill the gap that previous researches have not sufficiently covered. This thesis involved the use of a multiple case study by interviewing four international fast fashion companies based in Sweden, Stockholm. These companies are Bik Bok, River Island, Monki and Vero Moda. The researcher used a face to face interview method and telephone method. In total ten (10) interviews have been conducted.  

    Findings: The main finding of this research study is that the four e-commerce companies employed social media as a marketing strategy. Through thorough analysis it was found that Instagram was the most dominant of all social media platform. The use of social media marketing is vital for these fast fashion e-commerce businesses as they can have direct contact with their customers, attract new customers and to get to know their target market. These four companies opened an e-commerce business to offer product datasheet and to expand market for niche products. However, social media have also influenced few of these e-commerce businesses by the use of word of mouth.  

    Limitations: The limitation of this study is the lack of having the perspective of managers in the department of social media. The work could have been improved if the researcher was able to be in contact with those people in order to have a better validation of this research study. Moreover, there were inadequate resources or authors that have specifically covered the influenced of social media on fast fashion e-commerce firms and how they operate.  This could be seen as the research gap.  

    Suggestions For Further Research: As this research study only covers the influence of social media on fast fashion e-commerce businesses.Further study can be conducted on the perspective of fast fashion e-commerce customer’s perspective. Moreover, a bigger sampling of respondents can be collected rather than only collecting data from 2 or 3 people from each company. There might be a possibility if the chosen sampling  was bigger; the  researcher could have  had more  concrete  and solid research study.

    Prejudice Within Native American Communities: - a literary study of the prejudice expressed in Love Medicine and The Absolutely True Diary of a Part-Time Indian2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Native American characters in Love Medicine and The Absolutely True Diary of a Part-Time Indian experience prejudice from other Native Americans and suffer from internalized norms and values. This study examines whether or not the prejudice the fictional characters in Love Medicine and The Absolutely True Diary of a Part-Time Indianexperience and express as Native Americans unite them as a community or not. It also investigateshow they view white society andif the Native American characters have prejudice against the members of their own tribal community. The analysis is partially based on postcolonial theory and focuses on terms such as internalisation, acculturation and prejudice. The thesis found that the communitiesare united on the premises that they conform to the Native American norms but any deviation from these norms has the potential to divide them.

    Customer Satisfaction Drivers for Industrial Vending Systems: Evidence from the Manufacturing Industry2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Problem: Development of a firm’s offering is a vital weapon for competition. Obtaining knowledge on customer expectations and translating those into product development and superior service delivery is surrounded by prioritisation decisions. Industrial vending systems are proven to be a growing field in terms of deployments but have received little academic attention, especially regarding service quality perception to support customer-oriented innovation processes for suppliers, facilitating such decisions.

    Purpose: To identify key drivers of positive service quality perception and customer satisfaction as well as trust and commitment indicators for business-to-business industrial vending systems.

    Method: Through an explanatory approach, qualitative data on multiple cases was gathered. 14 in-depth semi-structured interviews were held with customers currently using a specific industrial vending system.

    Conclusion: Solution characteristics of industrial vending systems impact service quality perception through compliance with customer requirements. A total of 13 customer satisfaction drivers were identified for the investigated industrial vending system, the most important being efficiency, user-friendliness and timeliness. Further, the presence of individual- and company level trust in customer-supplier relationships positively impacts commitment intentions.

    Contribution: Adds novel knowledge on customer satisfaction for industrial vending systems and contributes with suggestions for managers on how trust and commitment affect customer satisfaction, which can be incorporated into the value promise design, product development and marketing strategies.

    Biokol i stadsträdens växtbäddar: med fokus på Stockholm stad2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The ground is an important factor to consider in today's tough climate for our urban trees. Especially for the trees that shall live in the most vulnerable parts of the city, such as the square, along heavily trafficked roads or surrounded by only paved surfaces. One solution is structured soils which is used in many cities in Sweden but also in other countries. An interesting new development of structured soils where AMA-soil has been replaced with biochar is now being tested in a project in Stockholm. The focus in this paper will therefore be on how biochar is used practically in the tree plant beds and the effects this has on the trees' development.

     

    The purpose of this paper is to get an insight on how biochar in urban tree plant beds are used with examples from Stockholm Biochar Project. And also to examine the parameters used to measure the effect biochar have on tree growth, and to assess the impact of biochar has on the trees.

     

    The work of this paper was carried out as an interview study and was then also combined with research in scientific books and articles. The interviewee is active in the area and works as a tree specialist at the traffic office,Stockholm city and complicit in Stockholm Biochar Project. Researched have been done in various databases where the keywords biokol, biochar, terra preta, urban city trees and tree inventory have been used.

     

    The construction of the plant bed with biochar in Stockholm city has proved to be similar to the old model, but it differs in that the AMA-soil has been exchanged for biochar and also in that the dimensions of the macadam instructured soil is changed.

     

    The parameters used in the Stockholm city to measure tree growth are stem circumference. But there are also other parameters that could be used to measure growth and these could also be applied to assess effect of the biochar on the tree.

     

    In a comparison of tree growth, where tree of the same species had grown in similar conditions but in three different types of plant beds, the results showed that the trees planted in biochar did not have the best growth.

    Kolinlagring: Hur kan målet om 4‰ praktiseras inom småskaligt ekologiskt jordbruk i Sverige?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The thesis examines the potential for sequestration of Soil Organic Carbon (SOC) in Sweden based on small-scale agriculture and horticulture. The essay is written from a perspective where climate change has reached a level where it is no longer enough to limit emissions, the earth must in addition serve as a sink for carbon dioxide and thus long-term storage of carbon (IPCC 2014). The initiative of 4 per mille (4 ‰ initiative, 4p1000.org) was initiated during the COP21 climate summit in Paris, which was seen as a step to move to concrete action in the context of agriculture in collaboration with civil society. The initiative is based on the knowledge that terrestrial systems hold far more carbon than the atmosphere, and that plants potential to facilitate carbon sequestration in soil is an underutilized potential in mitigating climate change. An additional and long term carbon storage of 0,04%  annually of the already existing SOC would not only drastically mitigate climate change, but also contribute to increased food security and adaptation to climate change as an increase in SOC means an increase of Soil Organic Matter (SOM), soil health, fertility and resilience.

    Literature studies support an analysis of carbon sequestration as a concept, and serves as a base from which questions related to carbon sequestration in Swedish farmland are formulated. The potential for carbon sequestration in Sweden is examined from the perspective of the 4 ‰ initiative, with a review of methods advocated within the initiative; eg.  cover crops, mulch, no-till/low-till, polyculture, intercropping, crop rotation and succession, agroforestry systems and perennial crops, buffer zones, organic residue amendments and optimized grazing. Relevant methods and concepts such as biochar, conservation agriculture, regenerative agriculture and holistic management are also described. This is complemented with descriptions of four practical examples of horticulture and farming in Sweden in order to anchor the theory into practice. All practitioners have been selected on the basis that they have a conscious desire to promote carbon sequestration in soil. Rather than describing these practitioners solely from the perspective of carbon sequestration, a broader view is presented mirroring the need to address carbon farming from an angle of holistic context and agroecology.

    With the support of scientific references and qualitative interviews, the study highlights the importance of; multifunctional approaches; established root biomass and ground coverage; increased net primary production (NPP) through plant available nitrogen; the potential of biochar as well as mycorrhiza for long term carbon sequestration. The study also highlights the great need for research in Swedish contexts in bringing clarity to questions around soil saturation of SOC in cases when rare methods such as agroforestry are used. Finally, the need for a more radical change within agricultural practices is highlighted as well as the need of support to practitioners who want to explore new regenerative ways of managing soils which promote carbon sequestration, food sovereignty and climate resilience.

    Det autobiografiska minnet relaterat till alkohol- drog missbruk2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study was to investigate life goals through an autobiographical memory perspective in people with addiction problems. They had already undergone detoxification and were drug- alcohol- free. No difference was shown in past and future life goals. Nor was there any difference in how the participants had succeeded in these goals. However, participants were shown to fail most with life goals related to close relationships. The study also showed that participants remembered more future than past life goals. Finally, it was shown that most of their autobiographical self- grounding memories were of negative valance.

    Outsourcing av ekonomifunktionen: Strategiska faktorer som motiv till outsourcing2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aim: Prior research has shown that there are economic, sociological and strategic factors that affect the decision of outsourcing in companies. Research has mainly focused on outsourcing in big enterprises, why researchers asks for more studies focusing on small and medium enterprises. Therefore, the aim for this study is to provide understanding of which strategic factors small enterprises sees as motives for outsourcing and what importance the different factors have.

    Method: The study is based on a social constructive and hermeneutic perspective. Further the study has taken a qualitative research strategy and an abductive research approach. The theoretical framework is built on prior research and the empirical data has been collected by ten semi-structured interviews with respondents from different enterprises. The material has been processed and analyzed to present a contribution.

    Result & Conclusions: Study results show both similarities and differences with previous research. All strategic factors presented in the theoretical section were confirmed as the motives for outsourcing by the respondents in the empirical part. What distinguishes the empirical data from the existing theory is the rank of the factor that is considered the strongest motive for outsourcing.

    Suggestions for future research: Given that the respondents' answers clearly were categorized on the basis of the position of the respondents had on businesses, we believe it would have been interesting to examine the different categories separately. Another suggestion for further research is to divide and study the various components of the finance function separately, this because we could discern clear differences between respondents' opinions depending on which part of the finance function outsourced.

    Contribution of the thesis: The study has provided a theoretical contribution in the sense that the results from the empirical data differs somewhat from earlier research. The study has also led to a practical contribution that suppliers of accounting services could use in daily operations.

    Feasibility Study of Small Hydropower/PV/Wind Hybrid System for Off-Grid Electrification of Liben and MedaWoulabu Villages2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    According to the International Energy Agency 2016 statistics, Ethiopia is among the lowest countries in annual electricity consumption, 70 KWh/capita. Rural areas hold more than 80% of the country’s population and less than 30% of them have been electrified. Most of the population (the rural areas) still predominantly depend on traditional biomass energy sources for cooking and heating, and household lights are provided mainly by kerosene and biomass including this study area, Tadacha Rarasa, which consist of 4100 households with 6 members, totally 24,600 people[1, 2].

    The feasibility study of hybrid system consisting of small Hydro, PV, Wind and Battery is carried out using HOMER as a tool for optimization and sensitivity analysis. TURBNPRO software also assists for the optimization of the small hydropower which is suggested to utilize the 2.2 m3/s ecological flow of the Genale 3 multipurpose hydropower plant’s reservoir. The wind speed and solar radiation data of the site is collected from NASA. Then, the wind speed, solar radiation, electric load and hydro data is input to HOMER in their respective appropriate format for simulation and analysis of the proposed hybrid system.  Electric loads of the community is estimated bearing in mind the irrigation, fishery and other opportunities which will arise after the multipurpose project completion in addition to basic household demands. The daily average estimated residential consumption by each family is 9.118 kWh and the daily average total energy consumption per person is 1.872 kWh.  

    After optimization and sensitivity analysis using HOMER, several different feasible configurations of Hydro, PV, Wind and Battery hybrid system has been displayed with a range of 0.049 to 0.067 $/kWh cost of energy. The optimum configuration becomes Hydro/PV/Battery hybrid system with 0.049 $/kWh levelized COE which is closer to the national energy tariff, 0.032 USD/kWh. The optimum Hydro/PV/Battery hybrid system generates annually 18,647,372 kWh with 0.18% capacity shortage and 0.15% unmet load. The hydropower supports the base load and the PV supplies for the peak load demand in the daytime which shares 19% of the total electric production.

    Adaptation of Solar Energy Driven Absorption Chillers for Air Conditioning in Commercial Building2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The most recent analysis of energy usage in the country reveled that nearly 50% of the power generation is used for air conditioning and mechanical ventilation most of which is used by commercial organizations. The grid generation mix that contains a high percentage of fossil fuel makes such energy usage environment unfriendly. Although absorption refrigeration is an old technique its economical application is limited to applications where cheap or waste heat energy is available despite decades of R&D, due to low COP, high initial cost and larger size. Heat input at Moderately high (over 120ᵒC) temperature and need to release large amount of heat to the environment through liquid or air cooling makes absorption chiller less conducive in cooling. Yet, being a tropical country, Sri Lanka has a better potential in adopting solar driven absorption refrigeration, if the chillers are operated at low temperature heat input that also promotes efficiency in storage that is mandatory due to fluctuation of energy source, subject to economic feasibility.

    The project aims designing and modeling of a solar power driven absorption chiller system that is adoptable to a selected medium size commercial organization. The proposed system uses heat energy around 100ᵒC and reusing fraction of energy expelled to the environment by suitably modifying operating parameter and thereby increasing efficiency of the system. Reduction of such heat losses and reducing heat input is achieved with the use of secondary heat exchange (brine) system that optimizes the energy usage. This arrangement will make efficient usage of solar heat storage, even in the considerable absence of solar power. System modeling and simulation of both basic double effect chiller and its modified versions were carried out and compared to evaluate improvement. The simulation of the modified system was used to obtain working parameters of the chiller so that a suitable solar collector, chilled water and heat rejection systems can be designed. Operational conditions of the cooling system are measured by the state sensors that feed inputs to the control system to achieve the optimum efficiency and their technical details are also included in the report.

    Branding for startup companies in Sweden: A study on startups brand building2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aim: The aim of this study is to explore the factors that influence the brand building in startup companies.

    Method: This study implements a qualitative approach and consists of twelve startup companies located in Sweden.

    Results and Conclusion: The findings suggest that the design of a brand (name and visual aspects), the use of social media, event participation and establishing partnerships is important parts of brand building. In addition, startups frequently make use of employees’ and entrepreneurs’ individual personality for branding purposes. Not only do all participants view branding as an important part of their business but a few respondents even feel it is crucial for the survival of their business.

    Suggestions for further research: The participants of this study reside in separate industries. This, combined with the sample size is not evidence enough to draw conclusion upon similarities and differences between startups branding practices in terms of industry. Thus, this could be interesting undertaking in the future due to the limited research on this topic.

    Contribution of the study: This study adds to the existing body of knowledge by uncovering factors such as brand design and social media, to name a few, that is used by startups to build their brand. As a result of this study insights has been given on the importance of branding and the strategies used to increase the brand equity of startups.

    Solar - Biomass hybrid system for process heat supply in medium scale hotels in Sri Lanka2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study aimed at evaluating and demonstrating the feasibility of using Concentrated Solar Thermal technology combined with biomass energy technology as a hybrid renewable energy system to supply the process heat requirements in small scale industries in Sri Lanka. Particularly, the focus was to apply the concept to the expanding hotel industry, for covering the thermal energy demand of a medium scale hotel.

    Solar modules utilize the rooftop area of the building to a valuable application. Linear Fresnel type of solar concentrator is selected considering the requirement of the application and the simplicity of fabrication and installation compared to other technologies. Subsequently, a wood-fired boiler is deployed as the steam generator as well as the balancing power source to recover the effects due to the seasonal variations in solar energy. Bioenergy, so far being the largest primary energy supply in the country, has a good potential for further growth in industrial applications like small hotels. 

    When a hotel with about 200-guests capacity and annual average occupancy of 65% is considered, the total annual CO2 saving is accounted as 207 tons compared with an entirely fossil fuel (diesel) fired boiler system. The annual operational cost saving is around $ 40,000 and the simple payback period is within 3-4 years. The proposed hybrid system can generate additional 26 employment opportunities in the proximity of the site location area.  

    This solar-biomass hybrid concept mitigates the weaknesses associated with these renewable technologies when employed separately. The system has been designed in such a way that the total heat demand of hot water and process steam supply is managed by renewable energy alone. It is thus a self-sustainable, non-conventional, renewable energy system. This concept can be stretched to other critical medium temperature applications like for example absorption refrigeration. The system is applicable to many other industries in the country where space requirement is available, solar irradiance is rich and a solid biomass supply is assured.
