Ett vårdinformationssystem i vårdens frontlinje : En fallstudie om Cambio Cosmic på en vårdcentral i Landstinget Kronoberg

In healthcare there is a rapid development towards introducing and implementing a wide range of Information Technology (IT) to aim for higher quality and more effective care. A common health information system (Cambio Cosmic) has been implemented in Landstinget Kronoberg. Clinical microsystems are the frontline units where staff and pa-tient meet. When the conditions in the microsystems are changed, it is interesting to de-scribe and analyse the consequences.The purpose of this study is to describe how health care staff uses a health information sys-tem and how they experience its functionality in their patient work. Initially, a literature re-view about the use of health information system was undertaken, followed by a qualitative case study based on interviews about how healthcare staff describes their reality.

Jämförelseförsök mellan ogräsharvning och radhackning :

The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

RFID på Kvarntuna stadsbibliotek : Teknikskifte som möjlighet till förändrat arbetssätt?

This two years master's thesis in Library and Information science, examines how the implementation of new technical equipment can affect how staff in public libraries organize their work and activities in the library. One Swedish public library in specific is the subject of research in this thesis, which has been anonymized as Kvarntuna city library. The study takes place in the beginning of the implementation of RFID-technology in the library. RFID, which stands for Radio Frequency Identification, is supposed to make the handling with different types of media in the library more efficient and in connection with the implementation one wants to reorganize work and activities in the library to make it even more efficient and also create a modern library.The thesis' method is qualitative interviews with six members of the staff. The theoretical framework of the thesis is a sociocultural perspective, especially inspiered by Roger Säljö, a Swedish professor in pedagogical psychology.

Optimering av OTEC-system

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.


Att kommunicera idéer och visualisera information i 3D :

In order to respond to a more complex community planning with increased cooperation and public participation, a common language and a common model to be used as a base for the communication process is needed. The thesis behind this dissertation for a master's degree is that a virtual 3D planning portal would respond to this need. Why and how are explained and described through studies of communication- and perception theory as well as technology and recent research. The introduction concludes that a broad participation and a transparence towards underlying information are important foundations for the coming work with the model. The first four chapters of the theory part show the benefits of using natural signs in our mixed cultural society, instead of the more arbitrary symbols. Using visual landscapes for storing information is motivated by the flexibility of our visual memory and its ability to understand complex connections.

Aktiv bullerdämpning i ventilationssystem

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

Gemensamt arbete inom IT mellan kommuner ? fördelar och nackdelar. En fallstudie på Göteborgsregionens kommuner

We are currently in the midst of the current information revolution and it is increasinglyimportant to allocate and utilize the resources spent on IT. To accomplish this, one solutioncould be to work together with IT. For municipalities, this can be a complicated process whenyou are dependent on the resources that are given and subject to laws regarding procurement,this places great demands on the Swedish municipalities.One solution could be to work collaboratively with IT across municipal borders, this studyexamines the advantages and disadvantages of this. The study was conducted using interviewand survey of various municipalities in the Gothenburg region. The study shows that there isjoint work across municipal boundaries but that communication sometimes fails, this provesamong other things that some communities feel they have a partnership with a municipality,while the other sees that they have no partnership.With the results from the study are discussed and problematized the current conditions thatexist between the municipalities today, and how they could change.
