In todays sociaty the use of information systems is wide spread and many corporations and buisnesses both in large and small spread make use of more advanced and sopisticated systems. Larger corporations have their own IT sections that maintain and updates their systems on a daily basis. They have the money and resources for it by how do the small businesses coop with it. How satisfied are the small businesses that are maybe runing on systems that might not be supplying the needs that the business is in need of. In this paper we investigate this question in the form of a questionnaire.

Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

This report contains CFD-simulations of cable tray fires in nuclear power plant applications with the CFD-code SMAFS. Furthermore the report evaluates the use of CFD-codes within this kind of problems. The assessment of this report is that there is a tendency towards the good use of CFD-codes but before using it solely more research has to be done on the subject..

A sequence of actions in the world have influenced the information science, one of these actions is the lateral movement in how companies use their IT-systems. IT-systems today, in comparison to before, are used by companies to improve their relationship with their customers. Every year a big amount of money is spent on developing and improving IT-systems. That is why it is important to develop and create IT-systems that are clear, and which encourage, enable and simplify a user?s action.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Sharepoint based applications, as well as design testing related activities to be incorporated into their existing software development framework. A test process maturity framework was chosen and applied for the design of the testing activities, while the test tool investigation resulted in guidelines on how to apply the tools effectively and circumvent any issues discovered..

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Ett branschanpassat affärssystem är avsett för organisationer verksamma inom samma bransch. Syftet med denna typ av affärssystem är att ge högre passform än standardiserade affärssystem och vara billigare än skräddarsydda affärssystem. Det råder dock brist på kunskap om hur dessa ska utvecklas. Genom vår litteraturstudie presenteras en kravinsamlingsmodell med utgångspunkt i Requirements Engineering som ska ge stöd för utvecklare vid insamling av krav för branschanpassade affärssystem. Utöver det identifierades ett flertal aktiviteter relaterade till modellen.

The work is performed at Forsmark Group AB as a final step in the Bachelor ofScience program in nuclear engineering at the University of Uppsala in 2013.The work is part of an ongoing process of streamlining project system model FKA.Streamlining the project model is an important aspect that affects all largecompanies that somehow have a project governing body when there is muchfinancial resources to save. Although the quality of the projects is positivelyaffected by efficiencyThe aim is to find possible common weaknesses and strengths of the project systemby interviewing a number of project managers, and using the systems in placeexamine the model.As part of the work also includes examining what project managers have to adjust tothe newly implemented system VPMM, and other newly introduced elements thathave been added to improve the efficiency in the futureProject System is a complex system that is influenced by many different parametersand participating individuals' attitude and personality. But then small changes in themodel could have major economic consequences.The thesis has generated results that show common weaknesses among the variousprojects and their project managers' general opinions about the project model. It alsopresents some possible solutions based on own thoughts and those interviewedobjects suggestions and comments..

The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they?re facing and offers a great potential to create significant competitive advantages.
