This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..

Denna studie beskriver innebörden i begreppen användbarhet och Activity Theory, samt hur den senare kan användas för att stärka utvecklingen av användbara webbplatser. Studien är genomförd ur ett utvecklarperspektiv. Resultatet av studien visar att användbarhet är en egenskap som uppstår i användandet av en artefakt, detta pekar både teori och empiri på. Studien visar också att Activity Theory kan användas på flera sätt för att stärka utvecklingen av användbara webbplatser. Vi anser att de resultat vi kommit fram till i vår studie gäller inte bara för utveckling av webbplatser utan de gäller även utvecklingen av informationssystem och informationsteknologi i en vidare utsträckning..

The background to this report is the author?s ambition to understand individuals? work situation, how it?s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems.The aim of this report was to explore managers? work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue:1. How does the managers experience their work situation?2.

AbstractIn my work on language development in preschool the purpose was to examine how and to what extent the pre-school supports children with special needs in their language development. Trough qualitative interviews with four preschool teachers, I wanted to see how they work with language development in preschool. In the study, Main questions asked in the inquiry :How do teachers and support children?s language development?What techniques, resources and tools available to facilitate language development? The conclusion that I made from my inquiry is that the primary language stimulation methods teachers use to encourage children?s language development are rhymes telling, books reading and song singing based on active selection of pieces that match the children?s maturity level.And how they are using different language stimulation techniques Karlstad model, TAKK (Signs of augmentative and alternative communication) and TRAS (Early registration of language development) to promote children?s language development. Keyword: Language development, language stimulation, treatment, communication, methods..

The project has involved the development of two kinds of shooting targets in partnership with Marcus Bergkvist and Christopher Åkerblom. The project from the client was divided into two parts. This thesis discusses solutions for hands-on transport, development of tripods and an overall design. The second thesis affect resetting systems for the products.The work was done with a process and methodology based on design perspectives. This process has involved the search of relevant data which has provided the platform and opportunity for appropriate and purposeful design work.Concept development has been done using hand sketches and Photoshop, where a simple visualization of different concepts for the tripods has been produced.

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.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

Agile systems development has in recent years become very popular, and many companies today claims to be working agile. At the same time there are studies about agile system development that indicate that there are difficulties in fully adopting the agile way. The purpose of this qualitative study has been to examine how true Swedish IT-companies conduct their agile system development compared to agile theory, and we have specifically for the purpose of the study designed a framework that has been used as an analytical tool. The framework helped us to maintain a structured and objective approach when we examined the participating companies and their practices. The study showed that there were differences regarding how true to agile theory the different companies conducts their agile projects, and that the differences in part depends on how long the companies have been working agile.

This paper is a research review in the realm of censorship systems andfiltering systems. It applies ethical considerations to the creation of censorshipsystems bringing forward discussion on the ethics of technology with thepurpose of limiting access to information.There is active research being done in the area of automatic content filteringand censorship systems. These are systems that can filter out undesiredmaterial, typically from the Internet, automatically. Used in some nations,many schools and even mandated in some libraries there are many ethicalquestions raised concerning censorship and access to information.Part of the review concerns the level of accuracy of these systems presentedby researchers in the field and the different approaches used. Reviewedarticles centre around automatic content classification and filtering ofpotentially harmful materials with regards to minors while some relate tocensorship technology in a wider sense.Results show a general lack of discussion concerning the ethics of thetechnology in the research reviewed.

Title:                          Leadership development of individuals in management positions Authors:                    Carl Renér and Peter Simonsson  Institution:                Linneaus University, School of Business and Economics Program:                   Human Resource Management Course:                      Business administration ? Organization including thesis, 15 credits Supervisor:               Olle Duhlin (Linneaus University, School of Business and Economics) Examiner:                 Mikael Lundgren (Linneaus University, School of Business and Economics) It is widely known that the role of managers may result in stress and a heavy workload. As a result of this negative effects organisations have to counteract and find new solutions and systems to facilitate and assist leaders in their work. A popular method for leadership development has come to show both in research and in practice, especially in recent years, this popular method is known as mentoring. This form of leadership development is often applied in so called mentoring programs.

AbstractWe live in a world today that is characterized by the Internet. We can get hold of people on the other side of the globe whenever we want and we can purchase what ever we want, from who ever we want, anytime we want. This development has made it important to find systems of dealing with the payment in a safe and secure way, both for a private person as well as for a company, when you do transactions with people far away, and those systems is the core of this essay. As a private person you sometimes need to transfer money to family members who live abroad and you can then use clean payments. This means that banks all over the world has systems which makes it easier when their customs wishes to transfer money abroad.

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.
