Projektering av ett småhus samt ekonomisk jämförelse av värmesystem
Design of a house requires knowledge of both technology and economics. Heating and ventilation shall be designed, costs are calculated and estimated and requirements must be fulfilled. Which heating system is to be elected is also a difficult choice, especially with rising energy prices as a factor.The choice of energy system is not always given, because it depends on several factors. Below is a comparison between district heating, geothermal heat pump and electric boiler from an economic standpoint. In a previous report appears district heating and geothermal heat pump as the best options.
Enhetschefernas roll i rehabiliteringsprocessen - Vilka möjligheter och hinder upplever de?
Abstract
This paper seeks to answer how well the unit managers in a community live up to its
responsibility for rehabilitation. What opportunities and obstacles center managers
feel that they have in the rehabilitation process and their expertise in rehabilitation
are adequate. The essay is based on qualitative, in which six interviews were
conducted to help capture the Heads of Unit subjective experiences. Five of the
respondents are heads of units in the elderly, and an interview with the
rehabilitation coordinator of the municipality. Respondents' comments and relevant
literature form the basis for this essay.

Metoderna för att komma fram till resultaten i denna rapport har varit intervjuer, en enkät, intern information och litteratur så som forskningsartiklar m.m. Denna rapport är en utredning av automatiserade test, vad man bör tänka på, vilka fördelarna är, vilka testfall som är möjliga att automatisera med mera.
Att konstruera hjälpsökande : En studie av sociala akter
A foundation of our welfare state is that we have a social safety net. This safety net is designed to pick up individuals who are in need of help and support to manage their way of life. This essay regards people who need help with care or people who need help with an addiction. This essay is a qualitative text analysis, which aims to see whether, and if so how, help-seekers are constructed in 40 social service documents within a municipality in central Sweden. We have endeavored to illustrate the power that the written word possesses and which categories of people are constructed depending on the language and content of the social documents.
Människan, kalven eller gödselbrunnen? Mjölkens destination och fördelning - hos mjölkbonden
A variety of food is produced and passes the whole chain by processing, transport and trade and finally it ends up with the consumer. But in many cases, the food is disposed before it is eaten. Some of the produced food does not even pass the whole entire chain before it turns to waste. The question about food waste in debates is a case of access to food for every human beeing. It is question of consumption of the resources, waste management and an issue of environmental impact.
Att ta vara på solens fulla uppvärmningskapacitet
The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.
Anestesi av ödlor
The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.
Frånluftsåtervinning i ett äldre flerfamiljehus : Hovgården - Borlänge
I detta examensarbete undersöktes möjligheten att installera värmeåtervinningssystem för ett flerfamiljehus i Hovgården som ligger en bit utanför Borlänge. I rapporten redovisas två olika sätt för energibesparingar som är aktuella för att ersätta borttagning av oljepannan som används i huset i dag. En rad svårigheter dök upp under undersökningen för installation av nytt värmesystem. Lämpliga lösningar kunde hittas efter mycket analys. Syftet med rapporten var att undersöka möjligheten och lönsamheten för installation av något av följande system; FVP eller VBX-modul som kan återvinna värme ur frånluften.
Klimatsimulering av ett kontorsrum : Hur de termiska stigkrafterna påverkar ventilationseffektiviteten
AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.
Adaptiv temperaturreglering av bostadshus
The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.
Kartläggning av Kassationerpå Bubs Godis
The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.
Vem gör vad - En fallstudie om federativ samverkan
This study aims to investigate how federations manage to balance the economies of scale through collaboration and autonomy. This is done through a case study on Länsförsäkringar. The lack of modern research on federations makes the federative structure an interesting field of study. Previous research has shown a general perception that an increased pressure on efficiency and economies of scale creates a stronger common unit that eventually creates an imbalance in the federation. It is therefore interesting to look at the balance, which exists between the member units and the common unit of a federation.

Glukos och leucin som potentiellt hjälpmedel i återuppbyggandet av muskelglykogen efter hårt arbete hos travhästar
The aim of the project was to study the effect of oral administration of glucose and leucin on the resynthesis of muscle glycogen after intense exercise in Standardbred trotters.
In a crossover design, 11 Standardbred trotters performed a standardized exercise test on two occasions in order to deplete muscle glycogen. The exercise test comprised a warm up period, 7 repeated bouts of exercise on an uphill 500 m slope, and a recovery period. After the exercise test horses received: 1) a solution of glucose and leucine via a nasogastric tube at 0 minutes and at 240 minutes post exercise and a single bout of glucose at 120 minutes post exercise or 2) water (placebo) at 0, 120 and 240 minutes. Blood samples for measurement of glucose and insulin concentrations were collected at rest, when the horses returned to the stables directly after exercise and throughout the 6 hour recovery phase. During the first recovery hour, samples were collected every 15 minutes and then every 30 minutes over the next 5 hours.

Denna rapport är en utredning av automatiserade test, vad man
bör tänka på, vilka fördelarna är, vilka testfall som är möjliga att
automatisera med mera. Rapporten kommer även att presentera
grunderna i testning av mjukvara, en introduktion till eXtreme
Programming och Test-Driven Development samt hur testningen
utförs på UIQ idag.
Då jag kom fram till att ett automatiserat unit test skulle passa sig
bra på UIQ kommer jag i slutet av denna rapport presentera ett
implementerings förslag. Man bör även införa en test driven
utvecklings metodik för att säkerhetsställa att det kommer att
utvecklas automatiserade testfall..
