VARN Ett nätverksbaserat 2D-actionmultiplayerspel skrivet i Java.
VARN A network multiplayer 2D action game written in Java. All games that support any form of play across networks is in one way or another affected by the delay, or "ping", that occurs from the time it takes for information to travel over the wires. Not only does it take time, it varies depending on how far away the connected partner is and the current status of the network you are on. Through the years a lot of different methods have been developed to combat these delays. I have reviewed some of these methods and implemented a synchronization system in Java meant to be used in online action multiplayer games..
Automatisk trimning av externa axlar
This master theses deals with different methods for automatic tuning of the existing controller for external axis. Three methods for automatic tuning have been investigated. Two of these are based on the manuell method used today. The third method is based on optimal placement of the dominant poles. Different sensitivity functions are important for this method.
Att utföra användarcentrerat arbete med små medel
Usability is a field within systems development which doesn?t get the attention it might deserve. Above all, it?s considered time consuming and expensive by many people in the industry. The current information regarding low-cost alternatives to achieve a more usable system seems to be almost non-existent.

Tidsberoende kvantkemiska beräkningar av optisk absorption hos polymerer och molekyler med litet bandgap
The vertical electronic excitation energies for the narrow-bandgap polymers LBPF, EP37 and EP62 have been calculated using Density Functional Theory (DFT). Also the vertical excitation energies for the acceptor unit of LBPF have been calculated using the Hartree-Fock (HF), DFT and Coupled Cluster (CC) methods. The calculations cover the visible and infrared wave length region and two strong transitions are obtained, one corresponding to the pi to pi* transition and one corresponding to the pi to Acceptor transition. The excitation energies obtained from DFT are below the corresponding experimental results and attempts have therefore been made to perform bench-marking calculations using a hierarchy of CC methods..
TILLFÄLLIGA EFFEKTTOPPAR I FJÄRRVÄRMEN : Kan man med hjälp av lagrad värme undvika att de uppstår i betonghus?
Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.
Fältmätningar av limträbalkars elasticitetsmoduler : utvärdering av tre mätmetoder
This study investigates three different methods for evaluating MOE,Modulus of Elasticity, in field measurements. The purpose is toinvestigate the possibility to use dynamic measurement methods infield measurements that hitherto (2010) has been performed with staticmethods. The objects of investigation are 20 glulam beams. The firstfield measurement took place in november 2007 and applied a staticmethod based on the standard SS-EN 408. The second measurement,described in this study, took place during summer 2010, and appliedstatic as well as dynamic methods.The MOE of wood is affected by a range different factors.
OneCore
The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.
Möjliga tillämpningar av BIM vid miljöcertifieringsarbete
In the construction industry today there is a significant technological revolution goingon. New methods for automated processes and information management are developedcontinuously. Intense studies are currently taking place to ensure ways and means toembrace the new technology of BIM.At the present, environmental certification systems are considered cumbersome andchallenging. However, the increasing demands of sustainable development in the constructionindustry imply that the environmental certifications will not disappear. ThisMaster Thesis examines the possibilities to apply BIM technology within the field ofenvironmental certifications to streamline the processes.The applications that provide the best opportunities are:- To use BIM to be able to, during the design stage, dynamically evaluate the resultor score a certain building will achieve.- To avoid unnecessary work through collection of data for calculations directlyfrom a BIM-model.- To be able to automate certain time consuming calculations that are currentlyperformed manually.- To automatically examine the completed model to ensure that the demands arefulfilled.The possibilities to use BIM within these areas are however limited by the technologyitself.
Värdet av att bygga grönt för kommunala bostadsbolag
AbstractThe real estate sector is today responsible for 40 per cent of the total amount of energy consumption within the members of the EU. All over the world there are collaborations within research and projects to find ways of reducing the amount of energy consumed by the real estate sector. In Sweden, a directive from the European Union has posed demands on authorities as well as on the private sector to reduce the amount of energy consumed by new building constructions. Together with the directive from the EU there are also new requirements and demands from Boverket for the real estate sector. These requirements mostly concern the energy consumption of kilowatt-hour per square metre and that the consumed energy also should be renewable. The aim of this study is to explain what kind of value municipalities experience in using certifications and environmental investments for new and existing buildings. Within the chapter theory, essential areas are described such as; environmental certification systems, economical viability, proceeds connected to building green, difficulties with building green, the performance of green buildings when affected by the behaviour of tenants and customer value. The following chapter describes the methodology with which we have conducted this study.
Erfarenheter från flerbostadshus som passivhus : En handflata och sex värmeljus
All new households were to be constructed with "near zero energy house standards" (NZE-house) by the year of 2020. The ambition to construct energy-efficient buildings had to increase rapidly in the spring of 2013.The purpose of this report was to increase the interest for building contractors to construct apartment buildings with passive house standards. By locating and evaluating experiences from an existing passive house a case study including interviews, field visits and document analysis was made. Research of literature regarding other passive houses in Sweden also helped to answer the following questions:- What positive and negative experiences have the study of the passive house meant to the involved stakeholders and residents?- What improvements can be made based on identified experiences?- How can an apartment building be designed as a passive house based on possible improvements?By collecting good and bad experiences, as well as improvements and potential design proposals, a diagram was created designed as a tool for developers when constructing apartment buildings with passive house standards.
Möjligheterna för Casabona-systemet
Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.
Vilka strategier och metoder kan vara användbara för en hållbar viktnedgång?

Another aim was to explore which factors can complicate or simplify weight loss maintenance. Fifty-four individuals who had maintained their weight loss more than a year, participated by answering a questionnaire. The questionnaire was constructed and distributed through the internet. The answers were registered in the program google docs. The participants mentioned successful methods and strategies, such as exercising regularly, the majority exercised 30 minutes at least five times per week.
Arbete med läs- och skrivutveckling i grundskolans tidigare skolår : Två pedagoger berättar om sina arbetssätt
The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.
Geoenergilösning för DN-huset
In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.
