The effects of two light programs on sleep in dairy cattle
Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.
Skulle du spela vidare? : En analys av narrativ och spelmekanik i episodiska spel
Episodic gaming is a relatively new phenomenon, that hasn?t been as extensively explored as other areas in game research. In this paper we research how episodic narratives and gameplay engage players compared to regular continuous storytelling. By exploring this we get a better understanding of how to design games that captivate players to the point of them wanting to play the next episode. A user study is conducted where ten players play two episodes each of an episodic game. We apply observations and interviews to capture a large amount of empirical data.
Spelifiering som motivationshöjande hjälpmedel för fysisk aktivitet
In today?s world there are plenty of technological tools and methods available with the purpose to increase peoples motivation for a healthier lifestyle. One such tool is a so-called activity tracker which uses sensors to log the user's everyday life and present it as automatic feedback. Gamification is a new and successful method to motivate and engage people in fulfilling tasks by using game elements and mechanics. In this study, five participants were instructed to use the activity tracker and pedometer Fitbit Flex daily for three weeks. Halfway through the study the participants were ranked and listed against each other in a ranking list in order to evoke competition.
Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
Utveckling av biopsiinstrument : Instrumenthållare för skruvnålsbiopsi
This Master Thesis has been carried out in cooperation with Ursus Medical AB (URSUS) which markets, assembles and sells the Rotex Screw Needle Biopsy Instrument ®. The instrument is delivered with an instrument holder. Customers had expressed dissatisfaction over that they needed to use two hands during a biopsy procedure, which resulted in a project to develop a new instrument holder.The project aim was to create concepts for how the new instrument holder should be designed, with focus on the mechanics. The new instrument holder would build on the existing basic principle that the screw needle and the cannula were screwed into the tissue. The thesis work would result in a technical solution and a functional prototype of the chosen concept.To achieve this, a generic product development processes were used and began with a comprehensive literature review.
Liszt och Alkan: Den virtuosa pianoetyden : Övningsstycke eller muterat monster?
Anders Rådén: Liszt & Alkan: the virtuoso piano study ? practice study or monstrous mutation? Uppsala: Musikvetenskap, 1998. C-uppsats (60 p).The purpose of this essay is to analyse a selection of studies by Franz Liszt (1811-1886) and Charles- Valentin Alkan (1813-1888). Can they be definedas practice studies, or are they reshaped in such a manner, as to establish a larger form reminiscent of the concert study? First of all, typical study characteristics of this time period are determined, then such characteristics are looked for in three of either Liszt's and Alkan's studies (from Douze grandes études S137 and Douze études dans les tons mineurs Op.
Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader
The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

Den svenska sällskapsspelsmarknaden : En studie om en bransch i utveckling från 1970 till idag
This essay is about the history of the Swedish board game-industry from the 1970?s to today. The essay focuses on the companies in the business and how they change during this period and about the causes of this change. This essay aims both at accurately describing the development of the industry as well as asking the question of what influence factors from outside of the industry have upon the change during this period of time. The material used in this essay is mainly extracts from interviews with people who have been working in the industry during the period, as well as literature on the subject and product-catalogues from certain years in the time-frame.From this material I have outlined the basic history of the industry.
Mek Stans 07
Mek Stans 07 is a machine developed for Tetra Pak in Lund as a 10p candidate theses project at Halmstad University. The commission behind the project involved development of a machine that punches holes in packages for the inspection division at Tetra Pak. The task for the machine was to facilitate the process of making openings for testing in the company?s other equipment.
Researches on different methods of cutting, types of automatization and possible designs were made. To implement the project a design and construction from the base where chosen.
Spelutveckling för Facebook ? från koncept till produkt
Abstrakt Under vårt kandidatarbete arbetade vi under 20 veckor med att utveckla ett webbaserat spel riktat mot Facebook. Vi använde Agile/Scrum som projektmetod för vårt arbete och förändrade metoden och utvecklade verkyg för att effektivisera den för vårt syfte. Vi kom fram till att det är svårt att göra ett socialt spel och att det viktigaste i produktionen är att se till att det finns en tydlig koppling mellan spelarnas interaktion med varandra och den grundläggande spelmekaniken. Vi tappade fokus under utvecklingen och lärde oss den hårda vägen vikten av att planera realistiskt och börja ifrån grunden när man utvecklar ett spel. Spelet vi skapade använder sig av slumpässigt genererad terräng, är skrivet i JavaScript och utspelar sig i en viktoriansk miljö.

Abstract
During our bachelor thesis we worked for 20 weeks with the development of a
web-based game
for Facebook. We used Agile/Scrum as our project planning method, changed the
method to make
it more effective for our purpose and developed tools for the method.
We came to the conclusion that it's hard to make a social game and that the
most important thing
in the production is to make sure that there's a clear connection between the
players' interaction
with each other and the foundations of the game mechanics. We lost focus during
the
development and learned the hard way the value of planning realistically and to
start from the
core when developing a game.
The game we created uses a random generated terrain, is written in JavaScript
and takes place in a
Victorian environment.
Keywords: Facebook, game development, web development, internet, social games.
Eftermarknadens möjligheter : En studie av Swecon AB:s tjänsteutbud
ProblemThe manufacturing industry is a mature industry where the profit margins are small and the competition is hard. This makes it hard for both manufacturers and resellers to gain market shares and reach reasonable profit margins only by selling products. Therefore Swecon who is reseller for Volvo Construction Equipment tries to find alternative methods and ways to increase their profit. An alternative source of income could be to develop the range of services that are connected to the ground products.PurposeThe purpose of the thesis is to examine how Swecon in southern Sweden can improve their offers of existing services connected to the ground product and investigate the demand of new such services.MethodThis study is based on a qualitative study of five of Swecons local offices and five of Swecons customers. The empirical framework is mostly based on personal interviews but in some cases information was retrieved by using phone interviews.
Så mycket på spel. En studie om spels narrativa förmåga och funktion i skolan
The purpose of this essay is to investigate and discuss the current state of game research and its potential usage in didactic situations. The essay is divided in two parts. Part one consists of an attempt to comment preceding contemporary game research and address possible myths that have been established. Part two aims to discuss games narrative capacity and function in education using the theories and terms laid down by Wolfgang Iser and Gérard Genette.Contemporary game research tends to focus on classic retro games, trying to form theories for a general understanding of the media. This is a useful method as long as the purpose of the study is to define how game mechanics and layout are formed.
Grundvattenavsänkning vid tunnelbyggnad ? tillämpning Förbifart Stockholm.
Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.
