Simulering av miljoner grindar med Count Algoritmen

A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Jag bara lärde mig! : En studie om typografi i läromedel för läsinlärning

We studied the initial process of reading, with a focus on typography, whether it ispossible to increase childrens lust to read in the age six to seven years old, byadjusting the typography and graphic design. We conduct this study through qualitative and quantitative studies, mainlyinterviews with a main focus on children in this particular age were used. In additionto the interviews a questioniare were sent out to a selection of students. The studyalso contained an interview with a pedagogue as well as studies of the current andexisting textbooks and teaching aids that is used on the school we are looking into.During the study we consulted educated pedagogues to get an understanding of thechildren and their learning and to be able to approach them in a suitable way.The theories we have been using were mainly from a typographic point of view.Other areas we explored were theories about reading processes. This study showedthat every child needs a method that is suitable for them and that the materialprovided today is typographically inconsistent. The childrens and teachers needs andwishes in typography did not correspond with the current teaching aids design. From this study the followning points were made about how to design a textbook forchildren in the first grade:? The typeface should be a sans serif.? The point size should be bigger than 12 points.? Text should be aligned to the left.? Sentences should be short without becoming abstract.? To maintain focus on the text the layout should be simple and unbarked.? The format should be designed after the pourpose of the publication, forexample when it is a complement to the textbook, the format should be of suchcharacter that it is easy for the children to bring home.? There should be a typographical consistency through all of the materialsprovided to the children..

Attityder till två olika brottstyper och till att hålla förhör med misstänkta gärningsmän

Attitydens omedvetna effekt är omöjlig att styra, då till exempel känslor såsom ilska, omedvetet kan påverka hur vi reagerar med vår omgivning. Med detta i åtanke undersökte föreliggande experiment huruvida det fanns någon skillnad mellan 44 kvinnor och 42 mäns, ur allmänheten, attityder till att hålla förhör med personer misstänkta för misshandel respektive skattebrott. Halva gruppen undersökningsdeltagare, läste en beskrivning av ett misshandelsfall och den andra gruppen ett skattebrottsfall, varefter deltagarna besvarade frågeformulär om attityder till kriminella respektive attityder till att hålla förhör med brottsmisstänkta personer. En två-vägs variansanalys med män och kvinnor samt brottstyperna som beroende variabler visade att misstänkta för misshandelsbrottet ansågs kunna förhöras med en signifikant lägre grad av humanitet, jämfört med personer misstänkta för skattebrott. En interaktionseffekt förelåg och simple effekt analyser visade att det var kvinnornas resultat som stod för interaktionseffekten.

Robotiserad produktionsanpassad magnetmontering för vågkraftverk

This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work.  This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner.  The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month.  According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .

Virkesgripen, ett geometriskt verktyg :

The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins. Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions. The study showed that it is the durability the users give priority to.

Uppbyggnaden av ett foderstatsprogram för dikor :

The object with this work was to create a simple feeding program for beef cows. Another object was that I could learn more about the properties and functions of Excel and Visual Basic. I used parts of a program I designed a few years ago. This old program was neither user friendly nor had it an appealing layout. Initially I decided how I wanted the new program to appear and on which foundation it should be built. I designed various forms into a spread sheet, such as lists and multiple choice buttons. Using VBA (Visual Basic for Application) I could create macros, which used the information chosen in the lists and with the multiple choices to calculate the feeding requirement or the feeding plan.

The projects goals were to see how well the original feeling could be transferred to real-time and how the transition itself went. The project have been completed with the help of the programmer Mikael Gullberg. The practical part of the project was executed between the dates of 25/4 ? 2/5.

Valmöjligheter i samband med prefabricerade badrum

This report deals with prefabricated bathrooms and the advantage, during the production process, they have compared to ordinary produced bathrooms.The work is done together with the building company JM. The common task is to investigate if the manufactures, in spite of standardized design can meet the concept of JM, i.e. high flexibility and adjustment towards the customer. In JM they are doubtful to the method, as they did not yet worked with prefabricated modules and think that the choises for the costumer will be limited.There will be a short resume of the progress of the bathrooms and its importance as sanitary and wellbeing.The recent problems with damage caused by damp in bathrooms. Have resultade in regulations.

Kapitalstruktur i fastighetsbranschen : En studie av svenska noterade fastighetsbolag 2005-2010

Recent studies made by Margaritis and Psillaki,have shown that a lower debt ratio and higher efficiency are correlated in their studies performed oncompanies in New Zeeland. Other researchers have been able to show a connection between other industries than the one used in our studies,among these are Titman and Wessler. These studies have been done with a great selection of companies in different industries and time periods. However most of these researchers have used traditional ratios and variables.This study aims to find and analyze connections between returns and lower debt ratios in real estate companies listed on the Stockholm stock exchange. Instead of the traditional debt-equity ratio we will construct our own taking long term debts and property assets.

The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation

The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours. In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.

Matarverk för Camcoil

By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.

Diskriminering är mångfaldens mörka sida : En studie baserad på samtal med sex mångfaldskonsulter

The purpose of this study is to examine how consultants define conceptions of diversity and discrimination. There has also been an aim to find connections to the term intersectionality within the consultants? definitions. The link between consultants and academic research is interesting to examine in order to examine what they base their definitions of different conceptions on. In order to explore these definitions and discussions I have used the qualitative method of interviewing each consultant separately at different occasions.

Implementering av realtidsvideolänk med MPEG- och wavelet-teknik

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.
