Termisk Vattenpump

 This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

Reflekterande eller reproducerande matematik : en jämförande studie mellan två undervisningsmetoder i matematik, det laborativa och det traditionella

In each classroom there is a teacher with good intentions wanting what´s best for their pupils. But grades and tests in mathematics from 2009 in Sweden shows there is a crack between the subject being taught and the learning child. The purpose with this research is to find an understanding from a teaching and learning perspective of which teaching method is more suitable for teaching and learning mathematics by doing a comparison between two methods. The main question is:What are the advantages and disadvantages of the traditional and the laboratory method of teaching, supported by the two keywords teaching method and learning?This C-paper is based on a qualitative research aiming to gather an in-depth understanding of human behavior.

Kliniskt datainsamlingssystem med beslutsstöd - Användarutredning och gränssnitt för Sahlgrenskas akutintag

 Extra high requirements are made on all systems in health care that they are functional and usable,´something, however, that is not always the case. At Emergency Admissions at Sahlgrenska University´Hospital many systems are in use at the same time and it happens that much overhead is caused by having to fill in the same information in different places. In addition, data that is gathered is to a large extent saved in free text format, which means that it cannot be used in a larger context such as research, quality control or for decision support. Data is saved in the patient file only for the treatment process of the individual patient.A data collecting system with decision support functionality could be a first step towards reducing Emergency Admissions? costs and patients? waiting times by providing a structured method of data collection.

Igloo

This degree project has been performed along with Classic Garden in Gothenburg andBallongfirman Far & Flyg in Stockholm. Together we have developed a sun- wind- andrain protection. The protection is permanently assembled and mainly intended for publicenvironments as restaurants and outdoor cafés.The design on the sun protection was already done so our task has been to develop theconstruction and to build a prototype in scale 1:4 and one in scale 1:1. The look of thesun protection is approximately as the name implies, equal an igloo. The lamellae aregoing to fold out in different steps all the way down to the ground and the both sides willbe independently of each other.The first stage in the project was to develop differently principle proposal on how thefunction will work when folding in and out the protection.

Svenska hedgefonders investeringsstrategier och deras riskexponering

In this paper Swedish hedge funds and strategies are discussed and analysed. These new financial forms seem to draw recently a huge attention both in media, press and the academic world. The fact is that hedge funds have existed already for a long time but it is still known too little about them. After the introduction of hedge funds, different asset pricing models are discussed including the most basic of all ? CAPM and further Fama and French three factor model as well as the expanding model with conditioning approach.

Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

International and national genetic evaluation of beef cattle : validation of national genetic evaluation models

After a workshop in Kuopio held in June 2006, Interbull decided to go forward with the development of a system for beef international genetic evaluation and a three year project called Interbeef was launched in June 2007. The participating countries are so far limited to Europe and the only trait evaluated at present is adjusted weaning weight (weight at 200 days). The results from a first international genetic evaluation have been shared with the countries but are not yet official. The evaluation is based on data from purebred Charolais and Limousin. To achieve good estimates of proofs in an international context it is important that methods for data validation and model selection are implemented.

AimThe specific questions in the theoretic part were:What is contained in the terms "balance and balance skill" and how can this skill be measured?The specific questions in the empirical part were:How does balance skill in different age categories of children correlate with biological and physiological parameters such as age, gender, body height, weight and level of physical activity?MethodsLiterature search based on books and scientific papers related to the questions posed above. Selection was made at libraries and on?line through "Pubmed". Specific search words were used.

Utveckling av en ytmonterad fördelningsmätare som underlag för individuell debitering av vattenförbrukning i fastigheter

The master thesis, conducted at Metrima AB, concerns the development of a non-intrusivedistribution meter as a basis for individual tap water billing in apartments.The project is conducted in response to the market interest in individual tap water billing inapartments as an answer to environmental concerns regarding water consumption. Due to thehigh installation cost of traditional water meters, a new method of determining waterconsumption, without having to cut water pipes, is proposed.The proposed method distributes the total water consumption for an apartment complex toindividual apartments according to distribution meters, measuring water run-time, in eachapartment. The water run-time is estimated by measuring the water pipe?s outward vibrationsand temperature changes.A test environment was established and a prototype built, using a tilt- and vibration sensor forvibration sensing and a precision temperature sensor to measure temperature changes. As bothsensors work well in the test environment, further testing was done in 3 apartments for aduration of 5 days.

Inclusion Body Disease hos boa- och pytonorm : diagnostiska metoder

Inclusion body disease (IBD) affecting boas and pythons is a serious and common disease. Boas can be clinically healthy carriers, which makes control of the disease difficult. The causative agent has not yet been confidently identified, and therefore there are no serodiagnostic tests available. Today, histopathologic examination of tissue biopsies is the recommended antemortem diagnostic method, but there are several disadvantages. The objective of this study was to compare the sensitivity of two diagnostic methods ? liver biopsies and blood smears, and to evaluate ultrasoundguided needle biopsy of the liver.

Identifiering av immateriella tillgångar i samband med företagsförvärv enligt IFRS 3 -En studie av resultateffekt och resultatmanipulering

Bakgrund och problem: Goodwillpostens behandling i redovisningen är ett ämne som diskuterasflitigt i branschrelaterad litteratur. Problemet är att bolag i olika grad identifierar immateriellatillgångar, en skillnad som får följder för om värdet skrivs av eller nedskrivningsprövas. Dånedskrivning i litteraturen anses medföra högre resultat kan underlåtelse att redovisa immateriellatillgångar användas i syfte att påverka resultatet. Denna resultatpåverkan kan även utnyttjas som ettmedel för att gynna företagsledare i samband med särskilda situationer i företaget.Syfte: Syfte med studien är att se huruvida de studerade bolagens redovisade resultat påverkas avatt företaget har identifierat samtliga immateriella tillgångar som ingår i goodwillposten, vilkaskrivs av över en bestämd nyttjandeperiod, jämfört med nuläget att posten nedskrivningsprövas.Givet att resultaten skiljer sig åt undersöks om indikationer på resultatmanipulering finns i detempiriska materialet.Avgränsningar: Studien omfattar de bolag, inom branschen för konsumenttjänster, som vidstudiens tidpunkt var noterade på någon av listorna Small Cap, Mid Cap eller Large Cap på NasdaqOMX Stockholm. De år som studeras är 2008-2013.Metod: Materialet som studeras är huvudsakligen inhämtat från årsredovisningar tillhörande deföretag som ingår.

Identifiering av gallringsbehov med hjälp av flygburen laserskanning :

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

Mätdatainsamling

Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.

A screening for Schmallenberg Virus among sheep and goats in Tanzania

Schmallenberg virus (SBV) is a novel arthropod-borne orthobunyavirus emerging in Europe in 2011 to 2012. Acute SBV infection causes diarrhoea, fever and reduced milk production in dairy cattle, but it is mainly the reproductive disorders (abortions, malformed foetuses and stillborn animals) in ruminants that have caused substantial economical losses. The prevalence of the virus outside of Europe is poorly investigated. SBV or SBV-like antibodies were detected in Mozambique in 2013, which raised interest for a similar study in Tanzania. In this study in Tanzania, blood samples were collected from 478 sheep and goats from 39 herds in 15 different villages in three districts, covering areas in the north, south and east of Tanzania. The epidemiology of the virus was investigated by tracing antibodies by ELISA and mapping of the virus by PCR was started.
