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.

This thesis has had its focus on ceramic shards found in a trench by the late neolithic western shore of the Ajvide site. The purpose of the thesis is to investigate if there are changes in the pottery between the test trench and the ceramics found by the graves, known as the main site. The author has compared the ornaments from the test trench with an ornament schedule made from over 50 000 shards from the assumed main site. Not only changes regarding ornaments has been noticed but also new techniques and raw material. The author has also implemented two 14C datings which backs his hypothesis that the shards from the test trench are younger than the shards that made the earlier ornament schedule.

Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.

The purpose of this thesis is to examine how e-commerce companies work with their relationships to customers. We have conducted a case study of two companies, Koll and Webbshoppen, both active in the e-commerce industry. Our empirical study has shown that it is important for e-commerce companies to create long-term relationships to their customers, but it can be difficult to create these relationships since the companies have little contact to the users of Internet. To build relationships, e-commerce companies market themselves through different types of media to create awareness. It is also essential to be situated high in search engines.

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.

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.

The purpose is to understand the planning process for residential buildings and toinvestigate the consequences of the choices made in the process. The project will alsoprovide broader knowledge in the design and development under the current law andpractice.The goal is to present a proposal on how a city near the site where water can bedesigned from a sustainable perspective. How can a residential neighborhood be anenvironmentally sound and sustainable region? New systems and techniques havebeen presented previously in terms of sustainable environments and these are intendedof being used in the project Quarter Water-mirror.The project has been implemented on the computer program ArchiCAD in whichdrawings and visualizations have been carried out. These drawings are included asannexes to the report.For information, calculations and drawings, laws for physical planning and Swedishstandard have been followed.Residential buildings have been designed on a site, which is 2, 5 hectares.

The IT industry is constantly evolving and it's more or less a requirement today for web developers to be familiar with and to be able to develop for all platforms. A technique that has taken hold and is now widely used is responsive design. Developing responsive design means adapting the layout to the viewing environment; the screen size. Another useful method when developing for different devices is the mobile first theory, which means developing for the mobile screen first. This is done to scale down the site and to clear unnecessary information in order to provide a better user experience.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.

The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.

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.

The field trial Exploatering av höga P-AL-tal (Exploiting P in heavily P dressed soils) started in 1982-1983 and included seventeen study sites placed across Sweden. Each site included three treatments, one unfertilized control (A), one aiming at replenishment of harvest removal, i.e. fertilized with 15 kg P ha-1 year-1 (B) and one over-fertilized (C) with 30 kg P ha-1 year-1. In this thesis data from the five longestrunning study sites are analysed based on four hypotheses. The hypotheses stated that in soils with high P-AL values and a pH over 6.0 P-AL will not decrease over time in the control (A) or in the replenishment treatment (B), that P-AL and P-HCl in the top soil will increase at all sites for the over-fertilized treatment (C) and that yields will not decrease as long as the P-AL is above 12 mg P 100 g-1 soil. My conclusions from the analysis of data from the selected sites are as follows: - A pH above 6.0 cannot guarantee a stable P-AL value in an unfertilized but phosphorus-rich soil. - The P-AL of unfertilized soils decreased faster at lower soil pH than at higher pH. - In the replenishment treatment (B) the rate of P-AL decrease seems to fall at a pH of 6.5. However, the influence of the soil type cannot be ignored. - P-AL and P-HCl did not increase in all over-fertilized treatments.

This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.
