Energieffektivisering och solenergi i en universitetsbyggnad : Undervisningshuset och Biblioteket i Uppsala
Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

This examination project focuses on the pupils and teachers experience of written assessments and grades. To highlight the significance of assessments and grades we will present the background to the development of the current educational view of knowledge, assessment and marking models. Today?s current laws and policies are described as is a proposal for a future law and grading scheme.The project is based on literature we have read and the empirical material is derived from interviews with eight students and two teachers. Four of the students are eleven years old, the other four are between seventeen and nineteen. The teachers teach years four and five. Each sex is equally represented. The interview questions are based on the students memories and personal development discussions in which the written assessments were presented.
Hardware-in-the-Loop simulering av motorservon på ett inbyggt system
This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

Systematisering av information på företag en fallstudie
The purpose of this paper is to investigate how a small company manages its information, primarily the organization of digital documents. The two dominating themes are classification and information politics, the former in the context of a corporate environment and the latter to help us to describe the situation at the company. The method used has involved observation of the company's current computer network structure and also interviews with six employees at different levels in various departments at the company. The result of our investigation has been the realization that, although logical structure is important when organizing documents in a digital environment, it is also necessary to have rules regarding its implementation..
Konstruktion och undersökning av effektsnåla slumptalsgeneratorer
Minskad effektförbrukning har blivit mer och mer intressant i takt med att fler produkter blir mobila. I artikeln Parallel Implementation of Linear Feedback Shift Registers for Low Power Applications, beskriver Menahem Lowy en metod för att konstruera slumptalsgeneratorer. Dessa är tänkta att vara effektsnålare än en vanlig enkel slumptalsgenerator, med återkopplat skiftregister. I det här examensarbetet har sex slumptalsgeneratorer konstruerats i VHDL. Två är baserade på Lowy?s metod och två är parallella varianter av dessa.
Sjuksköterskekallet nu och då
The aim of this study was to describe how retired nurses, educated in Uppsala, and students at Uppsala University's nursing program experience the importance of vocation in education and career choice. None of the participants had experienced vocation as a reason for choosing nursing as a career. The main reason was instead a desire to work with people. They also expressed that it was a profession like any other. The retired nurses said that the education was something of an up-bringing with religious elements.
Hundens kommunikationssignaler
This literature study summarizes the signals dogs use in intraspecific communication. The purpose is to clarify the way dogs communicate so that situations where their intentions are misjudged can be avoided. The signals are divided into olfactory, visual, auditory and tactile and every section starts with a short anatomic and physiologic description of the sense organ that is used to register the current signal type. The interspecific communication between dog and human regarding its development and function is brought up. To end with suggestions are given of how veterinary technicians in clinics can make use of knowledge about the way dogs communicate.
Managementrapport Perstorp AB
Vi har fått ett flertal viktiga insikter och lärdomar om nödvändiga ingredienser i god management. Först och främst en förståelse för hur viktigt det är med ökad självinsikt. Därigenom ökar förståelsen för andra personers beteende. Även det omvända gäller; genom andras beteende kan självinsikten öka. Lärdomen har implikationer på alla nivåer av management då en organisation grundar sig på samspelet mellan människor.

Kamratbedömning i svenska : Nio lärares tankar och erfarenheter
This paper studies how peer assessment is used as a strategy to improve young learners' results in Swedish as a school subject. Nine teachers are interviewed about their use of the method on 7-12-year-old pupils. Comparisons are made between the interviews and Swedish and international discussion on peer assessment. There are similarities between the practice of the teachers and what is said in the litterature about the method and its advantages and drawbacks. The teachers tend to emphasize the social aspects more, though.
Androidutveckling med slutanvändarens idéer som fokus
Under slutet av 2010 och våren 2011 har ett utvecklingsprojekt pågått hos AlexIT AB. Målet var att skapa en mobilapplikatioin för individer som vill bokföra sin alkoholkonsumtion. Som en del utav arbetet önskade projektgruppen bjuda in slutanvändare till processe, för att ta del utav deras idéer och feedback.Genom att låta en grupp slutanvändare själva skissa och beskriva sina lösningar och en annan grupp jobba fram en pappersprototyp tillsammans i en workshop gavs utvecklaren ett brett stöd för val i designprocessen.Det visar sig att de som individuellt skissa har inte låtit sig begränsas av antingen kravspeciifikationen eller mediet (mobiltelefon), utan har istället beskrivit funktionalitet framför design. Tvärtom har de som jobbat i workshop hållit sig inom ramarna för kravspecifikationen och mediet och skapat en komplett och implementerbar pappersprototyp..

Hållbarhetscertifiering av stadsdelar : En studie av BREEAM Communities praktiska tillämpning i svensk stadsbyggnad
In this diploma work the approach of determining the required amount of reinforcement in slabs exposed to pure tension is processed, on behalf of Ramböll Uppsala. It is a well-known problem in the industry that there are uncertainties in the determining of the amount of crack reinforcement, especially for structures exposed to pure tension. Cracking caused during the time of dehydration in concrete slabs is the most common defect according to statistics made by CBI[1], which provides numbers as high as 35 % of all the defects caused on slabs are generated by cracks. Comparisons between Sweden's former national standard BBK 04, Building Regulations for concrete structures due to restrained forces of shrinkage, and the current European standard Eurocode 2 are carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed.
