Sudokulo?sare: Ja?mfo?relse av ko?rtider fo?r backtracking och ma?nskliga strategier
Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigated in the report. .
Pseudoslumptalsgenerering : En studie av pseudoslumpsalgoritmer i allmänhet med fokus på C++11-biblioteketRandom samt implementation av en modifierad XORShift
Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..
Analys av fysiskt och administrativt flöde för provhantering vid Höganäs AB
In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.
Det handlar om tur: en kvalitativ studie av rättsprocessen vid kvinnofridsbrott
The purpose of this essay was to examine the experience of the judicial process concerning domestic violence from the perspectives of abused females and from some of the authorities and organisations which meet these women. The essay investigated several views of the judicial process in order to obtain a wide perspective. It responded to the following questions:- How are abused women treated by the authorities and organisations?- Are there enough resources and knowledge among the authorities and organisations?- Is there any collaboration between the authorities and organisations which the female meets in the judicial process and if so, how does it look like?- What does the aspect of security of person look like for the women which have been exposed to domestic violence?- What in the judicial process is important for the women's ability to move on in her life after experiences of violence in a relationship?This study was based on a qualitative method, where the interviews constituted of empirical material. The essay was based on interviews with two females who have experiences of violence in a relationship, two social workers from Kvinnojouren in Lund, two social workers from Kriscentrum in Lund, one lawyer, one prosecutor, one policeman and one social worker from Kvinnoforum in Lund.
En jämförande studie av IPv4 och IPv6
The Internet protocol of today has been used for over 20 years. A new version of the protocol has been developed to replace the old one. This is a direct result due to the explosive growth of the usage of the Internet. This follows by new demands which needs new solutions. This report brings up the old protocol IPv4, the new protocol IPv6 and shows what kind of changes that has been developed to meet the users demand.The report brings up two important aspects; internet security and mobility.
Rättssäkerhet och anstånd med betalning av skatt : En analys av 17 kap. 2 § p. 2-3 Skattebetalningslagen ur ett rättssäkerhetsperspektiv
The aim of this thesis is to investigate whether legal rights are upheld when wording and applying the postponement of payment of tax regulations of chapter 17 section 2 p. 2-3 of the payment of Tax Act. We also investigate how the wording of the regulations relate to the requirement of legal security.It has been questioned if the regulations concerning postponement of payment of tax are compatible with the requirement of legal security. Of course does not a taxpayer want to pay tax that he or she consider incorrect, and that has not been under trial by an impartial authority. If the request for postponement of payment of tax is rejected, the consequences for the taxpayer can lead to huge financial losses.
Mixi Print AB
Detta projekt är en hemsida för Mixi Print AB. Den ska fungera som en framsida
för företaget ur ett digitalt synsätt, en plats där det går att få fram
information om företaget och dess produkter snabbt och enkelt. Jag har arbetat
med programmet flash eftersom det ger möjlighet till bra och enkel men ändå
fräsch design. Till detta så har jag kombinerat php och MySQL för att kunna
koppla det till en databas. Som en del i projektet så har jag också reflekterat
över grafiska bitar på Internet jämfört med hur det var innan..
Systemutveckling av Trouble Report : Hur väljer och prioriterar man tekniska funktioner i vidareutveckling av ett etablerat system?
As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.
Berättande simuleringar : Om datorspel och lärande i GY11:s litteraturundervisning
Uppsatsen försöker kartlägga hur och om datorspel kan användas i samma syfte som skönlitteratur i den litteraturundervisning som GY11 föreskriver. Fokus ligger på beröringsytor mellan skönlitteratur och datorspel gällande lärande; främst identitetsskapande, moral och etik men också stilistiska drag och litteraturvetenskapliga begrepp. Med två exempel, Fallout: New Vegas och Grand Theft Auto IV, visas hur berättandet i datorspel kan ge mediet en plats i gymnasieskolans litteraturundervisning, samt hur immersion, perspektiv och interaktivitet kan ge spelare något som inte skönlitteratur kan ge läsare..
Att konstruera en gemenskap -teori och konstruktion av virtuella samhällen
Virtual communities are a phenomenon that is becoming more
common as the information technology comes with in reach for
the general public. This report will bring the theories and
construction of a virtual community together.
The purpose of this report is to describe the different theories that have
emerged from the research within this field and to examine the work procedures
that have been used during the development of a site for a MDA-community. The
MDA-website is a homepage on the Internet that was developed to bring the
students closer together. The report describes the work of the project group,
why the website was not completed and at the end the theories are looked at on
the basis of the construction of the website..
Java Teknologi för mobila enheter
Denna utredning har gjorts för att genomlysa en teknik som går under namnet
JavaTM 2 Micro Edition (J2METM). Vårt mål var att grundligt belysa tekniken och
tanken bakom J2ME samt att visa på för- respektive nackdelar med tekniken
avseende prestanda och säkerhet. Ett annat mål med utredningen var att visa på
praktisk användbarhet av Java i mobiltelefoner och konsekvenser på den mobila
infrastrukturen.
J2ME är en plattform skapad för att tillmötesgå behoven från den snabbt växande
marknaden av produkter som försetts med processorkraft. Dessa datoriserade
enheter är mindre än traditionella bordsdatorer och har därmed en annan typ av
fysiska begränsningar i form av t.ex.
Är resebranschens webbplatser strukturerade? - kriterier för en tydlig webbplats.
Internet består av väldigt många webbplatser där både kvalitet och kvantitet
varierar. Dagens webbplatser är ofta kompakta genom att de innehåller mycket
länkar, information och grafik. Detta medför att sidorna blir röriga och ger
för många synintryck för användaren. Det blir svårt för användaren att ta till
sig informationen och att tyda budskapet. I detta arbete utreds hur en
webbplats bör se ut för att vara så tydlig som möjligt gentemot användaren.
Barn av vår tid : Ett inredningskoncept för ett ungdomscenter
In the project Barn av vår tid (Children of our time), I have worked with Fryshuset in Malmo and created an interior concept which is designed to express Fryshusets identity, support and encourage its activities and to create a functional environment for young people as well as staff. The purpose of this concept is to help teenagers to feel involved, important and safe. Floor plan, materials and furniture is carefully adapted to support the activities of Fryshuset and to give young people a feeling of coming home. They are also of course chosen with care for the environment. I have studied interior branding, how the rooms can give a sense of security and homely atmosphere and how young people can actively participate in the design of the premises..
Undervisa engelska på engelska : Ett sätt att göra målspråket till arbetsspråk
High school students of today frequently come into contact with the English language throughradio and television. Many students even manage to read instruction manuals and understandhow technical devices work, such as, for example, computer games. However, most teachersunderestimate their students? ability and persist in using Swedish to explain how the Englishlanguage works. I have analysed how high school students manage when they take an Englishgrammar test in English.
FN och terrorism : En studie av världssamfundets policy sedan kalla krigets slut
The United Nations has a responsibility to combat acts of international terrorism, as they constitute a threat to international peace and security. In spite of this, there exists no generally accepted definition of the phenomenom within the UN. By examining resolutions on terrorism, this thesis aims to evaluate the UN?s policy on terrorism since the end of the cold war until 2003. The results show that the UN?s attitude towards terrorism eversince the end of the cold war has been condemning, but that the the events of September 11th 2001 has contributed to an even more firm approach to the problem.
