Modeflugor inom transportsektorn
During the time I've attended the programme to become a Transportation manager, I've been presented with quite a large number of different words. My purpose with this paper is to take a closer look at them, and see if they're sustainable concepts. This paper will be a literary study, and be on a wholly theoretical level. After a thorough examination of the various words, I've come to the conclusion that these words that I've chosen aren't just fad-words. They're going to be around for quite a while, this due to the fact that they're based on good ideas from the get-go.
Expansionsmaskiner istället för strypventiler - en effektivisering
In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.
Studie i exteriör belysning : med tillämpning på Bokenäs, Volvos fritids- och konferensby
When creating a good lighting design it is crucial to know how different types of lamps work. Knowing what kind of light they emit and in which situations they work well is also very important.
In this master thesis I present different types of lamps and give an account of how light is spread through the different shapes of luminaires, reflectors, filters and so on. I write about how our eyes register radiation and connections between lighting and how it makes us experience space. Furthermore I deal with the effect of artificial light on living organisms and the environment.
After the theoretical studies I deal with the places I have visited to study how different lamps and luminaires work and look like in existing lighting designs. These visits have also been inspirational to my lighting proposal for Bokenäs.
Bokenäs is Volvo?s resort and conference center which is situated on the Swedish west coast.
Kontroll av rengöring med ATP-luminometer hos livsmedelsverksamheter med pizzaberedning i Sundbybergs kommun
This BSc thesis is a part of an initial step of a collaboration between Skansen and Kenyan Wildlife Service (KWS) and constitutes of an inventory of the Nairobi Animal Orphanage run by KWS. Animal Orphanage takes care of orphaned and injured animals arriving from throughout Kenya. The project started out as a refuge and as a temporary place for animals in need of care and help. With time it has evolved to an establishment that resembles and functions more like an animal zoo. The aim of this inventory is to focus on how the biological needs of Congo grey parrots ( Psittacus erithacus erithacus) and cheetahs (Acinonyx jubatus) are met, in terms of management and housing.
Ett individintegrerat läsår - marginalisering eller möjlighet : En studie om tre individintegrerade elever i gymnasiesärskolan
The purpose of this study is to acquire knowledge about how interaction, participation and inclusion are affected by individual integration for three students in upper secondary education for pupils with learning disabilities. To be individually integrated means, in this case, that the students from compulsory school for children with learning disabilities are taking part in some of the programme-specific courses together with students from the regular upper secondary school. This study gets its inspiration from the ethnographic research approach, and uses passive observations together with interviews with students and their guardians as main methods to collect information.The school in question has not made any adjustments to make the programme-specific courses more adapted to the different needs, which is typical of integration. This study shows that the school presumes that the students with the help from the vocational teacher, but without any special needs educational help, themselves are to adapt to the conditions at the regular upper secondary school. This, together with the lack of special needs educational competence among the vocational teachers, led to a higher level of exclusion and an enhanced feeling of not being up to standard among the integrated students.The results also show that the integrated students maintain a strong wish to be included with the students attending the regular upper secondary school.
Personarkiv på Kungliga biblioteket -ordningar, kopplingar och krockar på ett nationalbibliotek
The departure point of this thesis is the context of the institution and the processes surrounding the handling of personal archives at the National Library of Sweden. These processes are examined using Actor Network Theory. Around the personal archive a network is constructed and contained by actors ? the archive itself, the librarian, the conservator, the researcher, organizational structures and others. Within this network choices are made of what is significant.
KRAV OCH MÖJLIGHETER FÖR STYRNING AV VATTENFALLS VATTENKRAFTSTATIONER
The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.
Inventory and evaluation of Nairobi Animal Orphanage : focusing on Congo Grey African parrot, cheetah and rehabilitation

Barn med utvecklingsstörning och en kvalitativ innehållsanalys av TEACCH-metoden och Lilli Nielsens pedagogik med avseende på kunskapssyn
SammanfattningMålet med det här arbetet är att analysera två pedagogiska metoder för barn med utvecklingsstörning, närmare bestämt TEACCH-metoden och Lilli Nielsens pedagogik, när det gäller kunskapssyn och då framförallt aspekterna hur barnet med utvecklingsstörning tillägnar sig kunskap och vilka former denna kunskap tar. Avslutningsvis undersöks vilka kategorier som kan identifieras ur de analyserade texterna (citaten).För att samla in data har jag använt mig av litteraturstudie men för att tolka och bearbeta data har jag valt att använda mig av kvalitativ innehållsanalys. Litteraturstudie innebär att jag söker efter specifika svar i litteraturen som jag sedan jämför.När det gäller frågeställningen hur barnet med utvecklingsstörning tillägnar sig kunskap enligt TEACCH-metoden har jag funnit följande kategorier: Strukturerad miljö, strukturerade aktiviteter och? hand på hand-metod?. När det gäller frågeställningen vilka former denna kunskap tar enligt TEACCH-metoden har jag funnit följande kategorier: Faktakunskap och Färdighetskunskap.
Livscykelanalys för koldioxidutsläpp från flerbostadshus
Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
Investeringsbeslut för energieffektivisering i monarken
The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.
En studie av olika ekonomiska modeller för mångbruk baserad på vindkraft
Today produces the wind power 2,5 TWh (TWh = terawatt hours) of Sweden?s total energy input of around 620 TWh. The Parliament has adopted a national planning objective where the wind-based electricity production will increase to 30 TWh in 2020. This requires that landowners will leas there land for wind power to wind energy companies. Such land leasing means that the landowner's business is considered to be a multiple-use.
Image i förändring : En fallstudie av SAS Sverige AB
During the early 1990´s, the Swedish commercial air traffic was de-regulated and the new market-condition made it possible for low-budget airlines to enter the Swedish market. The former monopolistic airline company, Scandinavian Airline Systems (SAS), was facing a new type of competition which had the advantage of offering much cheaper air trips than SAS. Adding the decrease of profitability that struck SAS as well as other airline companies after the terrorist attacks on the 11th of September, forced them to carry out a mayor reorganization programme. The programme, called ?Turn Around 2005?, was a direct economical measure that begun in 2002 and lasted until 2005 and resulted in a cost saving of 14,5 billion SEK as well as a notice or a transfer of 6000 employees.The purpose of this essay is to investigate if the opinion of the consumer, the image, corresponds with the profile that SAS wishes to mediate today.
?När börjar vi?? : En studie om raster på gymnasiet
This paper deals with breaks in upper secondary school. The aim with the study was to study the function of breaks for upper secondary students by investigating students? activities during breaks with the main issues: ?what does the students do during breaks??, ?how do they experience breaks?? and ?What is the relation between breaks and lessons??.A combination of the two complementary methods observation and interview was chosen to study this. The study was executed on an upper secondary school during one month. I have visited the school several times every week and written daily notes over my observations.
