Kostnadsoptimering av singelfrekvensnät för marksänd
digital-tv med Simulated Annealing

I det här arbetet har algoritmen Simulated Annealing undersökts med avseende på dess möjlig att användas för att minimera av kostnaden för ett singelfrekvensnät för digital tv. Undersökningen är gjord genom att simulera ett antal testfall för att utreda hur olika ingående optimeringsparametrar inverkar på slutresultatet. Alla försök har genomförts i ett egenkonstruerat simuleringsverktyg, gjort i Matlab. En jämförelse av resultaten för två olika sätt att hantera täckningskraven har också gjorts, Simulated Annealing med- respektive utan straff metod. Alla genomförda försök har genererat en betydande kostnadssänkning jämfört med startkonfigurationen.

Testing and optimization of Unicorn Fluid-Structure Interaction solver for simulating an industrial problem

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

GALS,Design och simulering för FPGA med VHDL

Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be reduced. GALS (Global Asynchronous Local Synchronous) is a wrapper that wraps a synchronous block and provides it with a clock. Multiple GALS-elements will make the whole system. The clockfrequency may be independently adjusted between each block.

Rosengårdsstråket : tankar om förankring och identitet

This thesis is studying Stråk* in an urban contexts. Thiswill be achieved through a study of Rosengårdsstråket inMalmö based on the question "What is a Stråk?".Malmö has experienced a major change in the last 15years.

LAN-refresh och WAN-migrering

This work has been carried out at a company in the region which has about 30000 employeeswith about 400 sites all over the world. The company outsources their network including theLAN refresh and the WAN migration. They needed help with an upgrade of their LAN at theirScandinavian headquarters and to find a new solution for their WAN. The reason why the upgradeof the LAN was needed was that the equipment was too old and did not pass the securityrequirements. They also required a solution to segment their LAN, which consisted of a singlelarge VLAN with 1,300 employees.

Toxoplasma gondii hos katt : prevalens, symptom och smittvägar

The thesis is about integration in the city and how integration can be improved through physical planning. Segregation can result in changing peoples? prerequisites in our society. Opportunities in life become dependent on what area of the city you live in or where you grew up. Integration denotes acceptance for all people, while different cultural and ethnic identities are preserved at the same conditions for everyone.

En kvalitativ studie i användarcentrerad webbdesign

Examensarbetet har gått ut på att genom kvalitativa undersökningar ta reda på hur grafisk form ochinformationsstruktur samverkar för att skapa användarcentrerade webbplatser. Målet var att ta fram en grund för huranvändarcentrerade webbplatser bör byggas. Denna grund är tänkt att fungera som riktlinjer för formgivare som villskapa användarcentrerad webbdesign.Studien visar att det viktigaste för att skapa användarcentrerad webbdesign är att involvera användarna kontinuerligti utvecklingsprocessen. Detta sker genom användartester och intervjuer med representanter för målgruppen. Vi harkommit fram till att graden av användbarhet spelar stor roll för hur målgruppen uppfattar webbplatsen som sådan,men också vilken uppfattning de får om företaget bakom..

Förekomst av Giardia i symtomfria valpkullar :

The flagellate Giardia intestinalis has been known to cause diarrhea in both man and dog. Results from epidemiological studies have indicated that transmission of the parasite from dog to man is plausible even though that route of infection has yet to be shown. Several international studies have shown that the parasite frequently occurs in asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not known though. In this study, faecal samples were collected at two separate occasions from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract. The samples from each litter were pooled but the samples from the bitches were analyzed individually.

Byggnadslogistik i infrastrukturprojekt för effektivare användning av grävmaskiner

Detta examensarbete har utförts på högskoleingenjörsprogrammet för Byggteknik och Design vid Kungliga Tekniska Högskolan i samarbete med Svensk Bygglogistik AB. Arbetet diskuterar betydelsen av byggnadslogistik i ett infrastrukturprojekt för att uppnå en högre utnyttjandegrad för grävmaskiner med stöd av logistiksamordningsverktyg.Sammanlagt har 2150 mätningar utförts under två veckors tid för att kartlägga utnyttjandegraden för en bandgrävare (EC250CL) och en hjulgrävare (Atlas 1505M) på ett referensprojekt i Stockholmsregionen.

Optimering av multiprocessorsystem med hjälp av schemaläggning

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

SL.se från användarens perspektiv : En granskning av Storstockholms Lokaltrafiks hemsida

This study is a thorough comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.
