Osäkerhet i energisimuleringar av flerbostadshus : Analys av fem nybyggnationer
Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.
Moderna kyrkor. Reflektioner kring ett övertaligt kulturarv
Churches are seen as one of Sweden's most valuable cultural heritage. They bear witness to a living tradition and gives us knowledge of society at large and therefore people's lives at different times. These buildings possesses a high value, which is shared by the vast majority, and they are protected by law. The concept of modern churches is in this essay the churches built after 1940, which is not covered by law. The older churches has therefore a cultural and historical value which the modern churches lack.About 600 churches are built after the year of 1940 and the total number of churches in the country is 3400.
Re-design av BEV-heater
Denna rapport beskriver det examensarbete som utförts på Calix AB under vårterminen 2013. Calix AB tillverkar värmare för bland annat batteri och kupé till fordonsindustrin. Uppdraget i detta examensarbete var att göra en omkonstruktion på BEV-heatern (Battery Electrical Vehicle) som är en batteri- och kupévärmare till el och hybridfordon. Problemet med den nuvarande konstruktionen är att den bygger på delar från äldre värmare till fordon med förbränningsmotorer, samt att konstruktionen inte är lämplig för produktion i större serier. Krav som Calix AB hade var:Integrerat ChassiMinimera tryckfallUnderlätta montering och tillverkningUppfylla standarder satta av fordonsindustrinKunna monteras ?in-line? i fordonetFör att kunna genomföra projektet var vi till en början tvungna att få kunskap om hur den befintliga BEV-heatern fungerar.

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.
Tidens anda - och den kollektiva arbetsrätten
Denna uppsats behandlar tidens anda och dess påverkan på den kollektiva arbetsrätten genom åren. Syftet med arbetet är främst att ge ett annorlunda perspektiv på arbetsmarknadens historieutveckling genom att inte bara undersöka händelsers sakliga bakgrund och utgång, utan även fokusera i högre grad på de krafter som ligger bakom processen. Detta görs genom att till en början redogöra för de centrala händelserna i den kollektiva arbetsrättens historieutveckling och sedan i följande kapitel fastställa vad tidens anda var under samma tidsperioder. Vidare görs en jämförelse mellan de båda historiegenomgångarna för att visa hur den senare påverkat, samt återspeglas i, den förstnämnda. Det framgår av denna jämförelse att det, under de perioder det skett omvälvningar på den kollektiva arbetsrättens område, funnits en viss anda inom Sverige som antingen hjälpt till att initiera processen eller underlättat dess fortgång.
Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder
The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.
Revisorers perspektiv på implementeringen av ett nytt regelverk : ? fallet komponentavskrivningar enligt regelverket K3
This essay deals with the principle of surprise warfare and its development as well as the adaptation of military action that had to be made to surprise the opponent in the modern era.The concept of surprise is divided into its components in order to clarify what is required to implement a surprising maneuver, to understand the complex concept and form a theoretical framework for gathering facts in the case study.Development and adaption are demonstrated by a comparative case study where Pearl Harbor illustrates an example of historical surprise and Operation Desert Storm illustrates a modern surprise. The product will then be analyzed in order to detect the development and how military conduct is forced to adapt in order to carry out a surprising maneuver. The results shows that the military action of performing a surprise attack has had a major development and is now carried out in a different stage of the attack..

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

By way of conclusion the coming generation problem is discussed in relation to professionalisation, the historical development, volunteer work, economy and national projects..
Virtual Reality : En ny veklighet för arbetsterapin?
Arbetsterapi är ett ämne som framhäver hälsa och välmående genom aktivitet. Det huvudsakliga målet som arbetsterapeut är att möjliggöra för personer att delta i aktiviteter i det dagliga livet. Virtual Reality är en simulation där datorgrafik används för att skapa en tillsynes realistisk miljö och denna värld är inte statisk utan integrerar med användaren. Syftet med denna litteraturstudie är att kartlägga hur och varför Virtual Reality kan användas av arbetsterapeuter. En systematisk litteraturstudie genomfördes och efter databassökning uppkom 14 artiklar som via en manuell sökning kompletterades med ytterligare 5 artiklar.
Vardag på ett särskilt boende för en äldre invandrare som inte kan det svenska språket : En observationsstudieAn observation study of the everyday life of an immigrant unable to speak swedish and living in a home for elderly
In Sweden the social assistance from a historical perspective, has been a part of the social legislation, since the 18th century. In that time called poor relief. Through the centuries this has established the social assistance we have today. With focus on the child, we have attempted to illustrate how the social workers consider the child perspective when they are dealing with the social assistance. We wanted to get a view of how the social worker reasons about needs the children have and how they can see that the benefit has been provided for.
Slagfältarkeologi : Metod och möjlighet att lokalisera och undersöka förhistoriska bataljplatser.
This essay is a study regarding the existence of Bronze Ages and Iron Ages battlefields in Scandinavia and the possibility to trace and find them by using the Battlefield Archaeological Method.Based on a theoretical background and results from historical battlefield research and excavation experiences, the discussion deals with some of the problems and possibilities of applying the Battlefield Archaeological Method on older places. The existence of these battlegrounds is also an unknown factor, and a major part of this study is trying to find evidence of their existence. For that purpose I am using as an example a deeper analysis of an Iron Age battlefield archaeological excavation in Germany in order to compare and draw parallels with the Scandinavian society of that time. I am also using the evolution of weaponry, in particular the sword, to show parallels between the Mediterranean and the Scandinavian societies in the matter of warfare and tactics..

Bidrar utställningen "Maria - Drömmen om kvinnan" till genusperspektivet inom det konstvetenskapliga fältet?
The purpose with this essay is to study if the exhibition, Maria-Drömmen om kvinnan has a gender perspective and if it contributes to the history of art. The study shows what kind of women the exhibition illustrates and what kind of perspective it has. By telling about the black Madonna I also show that there is another representation of the middle age women in the Roman Catholic Church at this time that the exhibition not have included. The study is also going to illustrate the difference between a genderperspektiv in art and a women?s perspective.
