Hur fungerar vårdens IT-system egentligen? : Jämförelse av elektroniska patientjournalsystem
To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.
Undersökning av Mekaniska Problem med hjälp av Datoralgebra
When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..
Dataspelsarvet - klassiker och kanonisering
This master thesis deals with computer game classics and a possible computer game canon. It looks closer at four computer game genres - adventure, RPG, action and strategy - in order to discern which games are considered classics and what characterizes them. To answer the first question a quantitative research method was used. 675 computer game reviews from 5 Internetsites were examined in order to see which games are mentioned most often in this context and therefore might be considered classics. To answer the second question a qualitative research method was used.
Tidsstudie - grovfoderhantering :
Since feeding fodder crops to dairy cows is a heavy and time-consuming but often
disregarded line of work, this study wishes to view the different possibilities that are
currently available to decrease the time to feed and apply this knowledge on an
existing farm. For this purpose, four farms have been studied due to what feeding
systems that are currently used and how long time the feeding required. The occurring
systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle
via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer
which fills an automatic feeder.
Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet
Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

E-handel i småföretag
E-commerce is a conception who many are taking about nowadays. E-commerce is associate with computer based business and it?s a new way to do business on. Users and system connect up to each other for effective mediate and transfer information. Within e-commerce there?s a lot of ways to do business on and it can for example be between a business and a another business (B2B) or between business and consumer (B2C).In this degree report have I reached if small business will invest on e-commerce and if they will, how.
HAVECA-modellen - En metod för att fortlöpande säkra ett internt nätverk mot tredjepart
This thesis will address a problem concerning availability of information
systems at an enterprise within the financial sector and its external
suppliers, so called trusted third party. The information system resides on the
internal network of the enterprise and must be available to both employees of
the enterprise and the trusted third party simultaneously. This contradicts the
company policy which
disallows third parties access to the internal network. The HAVECA-model
introduced in this thesis provides a framework of methods, each solving a sub
problem identified in the model. The identified methods are hardening,
verification, control and assurance, together supplying a method for
continuously securing the internal network against a trusted third party.
Digitalisera loggboken : En analys av utmaningarna med att utveckla IT-stöd för kunskapsintensiva verksamheter
Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in Computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.
Alternativ för värme- och kylaförsörjning i planerade kontorsbyggnader på Arlanda
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.
Development of Liquid Cooling for PCs
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.

Socialarbetares syn på datorspelande ungdomar : En intervjustudie om socialarbetares problematisering av ett nytt fenomen
The purpose of our study is to describe and understand whether, and if so, how social workers in school and in social services construct computer gaming adolescents as a social problem. We chose social workers who encounter adolescents with different problems. We have conducted qualitative interviews with vignettes to capture the social workers' reasoning about computer gaming adolescents and how they handle this in their work. The study shows that all social workers we interviewed had encountered adolescents with troubling computer gaming habits. In the study, all agree that computer gaming becomes a problem when it leads to deviant behaviour such as not going to school, staying up all night and so on.

Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.
Den flerspråkiga bibliotekskatalogen: Hantering av icke-latinsk skrift på bibliotek
The main purpose of this thesis has been to investigate librarians opinions about the need for and possibility to use non-roman script in library catalogues. We have also investigated the routines of handling materials in non-roman scripts in two Swedish libraries. The investigation was made in the light of the recent shift in character set in the Swedish National Library Catalogue Libris. This change will enable use of multiple writing systems in the future.Our findings are that a multicultural society requires special consideration to the needs of citizens who speak other languages than the majority of the population. This becomes difficult when the languages spoken have a different writing system than the one used by the majority.
