Bromodellering genom bromodulen i Revit Structure - Anpassning av programvara för skapande av ändskärmsbroar
This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Nytt ventilationssystem till djurstallar :
There is two dairy farms in Sweden with ability to be opened on both long sides, one outside
Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results
or not enough literature about natural ventilation and especially on this kind of air inlet, makes
my tests very interesting not only on Alnarp, but among other companies.
I would like to find out if there is any air movements direct on the cows, how high/low
temperature, air humidity, light intensity and noise standard inside the barn. Does
Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could
this system become the new dairy barn instead of the conventional barns in Sweden?
I am going to focus on the animals environment, after all they are the one who is going to
spend the most of the time in the barn.
I used five electrical loggers distributed inside the barn to measure the temperature and one of
the loggers measured the air humidity, every 15th minute. One logger were placed on the
outside which measured both temperature and air humidity.
Effekter av urbanisering på grönalgen trädgröna i Linköpings stad med omnejd. : Biologiundervisning i närmiljön
Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.
Kundlojalitet : en studie om vilken påverkan de demografiska aspekterna har på kundens lojalitet mot sin bank.
In Sweden today almost all people are connected to a bank in some way. It can range from loans, savings, shares, etc. They have a current account where salaries, student aid etc. is paid. Due to the large selection of banks, it has become more important for banks to be competitive in their services to their customers so they don?t change bank.
Distributed Operations : en framtida lösning för upprorsbekämpning?
Chefen för amerikanska marinkåren beslutade 2005 att påbörja utvecklingen av konceptet DistributedOperations (DO). Syftet med konceptet är bland annat att möta utmaningarna inom upprorskrigföring och?Small Wars? som kännetecknas av asymmetriska förhållanden mellan parterna. Grundidén medDistributed Operations är att skapa en fördel över motståndaren genom att uppträda utspritt ellerkraftsamlat och hela tiden kunna avge understöd till den ?lägsta enheten?.
Major vs. Independent : en undersökning om hur skivbolagsrepresentationen ser ut i svensk dagspress
Aim: The aim for this study of Swedish daily press is to see how the musical reporting is structured for the newspapers I have chosen to analyse. My main purpose is to investigate how the newspapers reporting are distributed between artists who belong to either a major record company or an independent record company. With this research I want to find out if there are any economic backgrounds to the content and if the reporting is equal to the market production.Method/Material: For this study I have studied, by quantitative research, every piece of musical reporting in seven daily newspapers for two weeks. Through thorough research I have determined the belonging of every article?s record company.
Förbättring av mjukvarubibliotek för parallellberäkningar med programmeringsmodellen Chunks and Tasks
Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.
Är lösenord informationssystemens akilleshäl? En studie av studenter vid Högskolan i Borås lösenord
Denna studie berör de lösenord som studenterna vid Högskolan i Borås använder sig av, och omdessa är tillräckligt bra för att skydda den information de vill skydda. Den tar upp de problemsom finns med att använda lösenord som autentiseringslösning, samt de egenskaper som skaparett bra lösenord.Ett bra lösenord innehåller fler än fjorton tecken och är en blandning av bokstäver (gemener ochversaler), siffror och specialtecken, och innehåller inga fraser, välkända uttryck eller ord som ståri en ordlista. Lösenorden krypteras ofta med en så kallad hashfunktion, en envägsfunktion somskapar en kontrollsumma. Om man på ett säkert sätt skall spara lösenorden med denna metod börman använda ett så kallat salt, en textsträng som gör själva lagringen säkrare.För att knäcka lösenord kan man använda sig av flera olika metoder: Så kalladedictionaryattacker, som skapar lösenord utifrån en ordlista; brute forceattacker som används föratt slumpa fram möjliga permutationer och sedan jämföra med lösenordet man vill knäcka; samtrainbow tableattacker, en metod där man använder färdiggenererade tabeller som innehåller allamöjliga permutationer.Vi har genom en enkät fått en bild av hur studenterna vid Högskolan i Borås lösenord ser ut. Vihar genom ett experiment bekräftat att dictionaryattacker kan knäcka 34 % av samtliga lösenord,och detta är endast en av metoderna.
Inre- och yttre motivation med SDT som förklaringsmodell : En studie av Sandvik Tooling
Title: Intrinsic- and extrinsic motivation with SDT as a model of explanation ? A study of Sandvik Tooling Level: Final assignment for Master Degree in Business Administration Authors: Samuel Norman & Erik Sandh Supervisor: Jonas Kågström Date: 2011 ? June Aim: From the basis of Self-Determination Theory find those motives that are the sources of the greatest motivation at Sandvik Tooling and determine if the employees are mostly driven by intrinsic- or extrinsic motivation. Method: The study has a quantitative approach where the empirical part consists of 24 questions from the SDT-theory?s Aspirations index that is divided into six groups evenly distributed on intrinsic- and extrinsic motivations. The questionnaire has been developed in Google forms and distributed digitally to the organisation by e-mail through a contact person at Sandvik Tooling. The respondents? answers are accounted for question by question in the empirical chapter and have been processed with a factor analysis and compared with the SDT-theory.Result & Conclusions: The results we received are in line with SDT-theory and whether people are motivated differently by intrinsic-Personal growth and Community contributions higher than all of the extrinsic motivational factors.
Koppar på drift
In my project, Cups on the run, I have studied the relationship between ceramic utility objects and different environments, when moving them off the table. My background as a potter has been the starting point. From there, I wanted to see if I could expand my craft to the space beyond. With the cup, which for most people has a clear function and a relation to us human, in repetitive structure I explored the spatiality and architecture in various environments. Life fascinates me through how everything is made up of tiny parts that together create the tangible and intangible.
Inpackning av giveaway-produkter
We performed our thesis at SCA Hygiene Products in Falkenberg. Our task has been to present a suggestion for a solution of the packing of giveaways that the company uses.In the current situation the work is performed manually, and the company wants to automate the process. In the following report, we present the different solutions that we have developed in our definite model. It includes a picking solution, a shaking table and trays. The product choices we have made are based on existing solutions.To help, we have used Fredy Olsson's books in principle and primary structure.

Diabetes hos hund : utfodring, motion och vikt som möjliga predisponerande faktorer
This is a study of some risk factors for Diabetes Mellitus (DM) in dogs. As a pilot study it is meant to give information to be used in a planned later, larger and better controlled study. The present study hypothesized that suboptimal feeding (high percentage of homemade and table foods), lack of activity and overweight contribute to the risk of DM. Twenty consecutive dogs diagnosed with DM at the Veterinary University Clinic in Uppsala between 2000 ? 2003 were chosen as the experimental group.
Integrering av iläggsskiva i matbord
Denna rapport har skrivits i samband med ett examensarbete i integrerad produktutveckling. Rapporten genomfördes under den avslutande kursen på designingenjörsprogrammet vid högskolan i Skövde 2008 i samarbete med företaget Lundbergs Möbler AB i Tibro.Rapporten redogör för designprocessen där en lösning för att integrera företagets iläggsskivor tas fram för deras matbord. Rapporten skildrar projektets olika delar från förstudie till slutligt koncept.Projektets inledande förstudie påvisade framförallt hur konkurrenternas lösningsprinciper ser ut, hur hanteringen av dagens iläggsskiva ser ut och dess hanteringsproblem samt ergonomin kring hanteringen av iläggsskivan. Det som framkom i förstudien låg därefter som beslutsunderlag för den fortsatta produktutvecklingen. Dessa områden gav en klarhet i om projektet var genomförbart och vidare vilka fysiska begränsningar och möjligheter projektet hade inför det fortsatta produktutvecklingsarbetet.Med den nya kunskapen bakom sig inleddes idégenereringsfasen.
