Solel och solvärme ur LCC-perspektiv för ett passiv-flerbostadshus

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

Vård på plats eller hänvisning av patienten med annat transportsätt inom ett specifikt sjukvårdsområde : en granskning av förekomsten av uppdrag där patienten inte åker med ambulans till vårdinrättning

SAMMANFATTNINGAmbulanssjukvårdens utveckling gällande medicinsk teknik och medicinsk kompetens har skapat möjlighet för ambulanssjuksköterskan att kunna vårda patienterna på en mycket avancerad nivå. Samtidigt har möjlighet skapats att triagera, prioritera och styra patienterna mot rätt vårdinstans till skillnad från tidigare då alla ambulansuppdrag resulterade i ett besök på en akutmottagning. Detta är en möjlighet som hanteras olika beroende på var i Sverige ambulanssjuksköterskan arbetar.Syftet med studien var att belysa vård på plats i samband med ambulansuppdrag inom ett specifikt sjukvårdsområde.Studien utgick från en kvantitativ ansats och var en journalstudie där ambulansjournaler granskades.Resultatet visar att det finns månadsfluktuationer över ett helårsperspektiv men att dessa är små och svårtolkade. Störst skillnad är det mellan november, 15,3 procent (n=489) och maj 11,6 procent (n=386). När dygnsfördelningen av eftersökta uppdrag analyserades framkom det att natten (22.00?05.00) är den tid då de flesta uppdragen relativt sett resulterar i att patienten inte transporteras vidare med ambulans.

Implementeringen av miljöansvarsdirektivet i den svenska rätten : En europarättslig studie om förvaltningsförfarandet vid miljöskador utifrån principerna om god förvaltning och processuell autonomi

The aim of this thesis is to examine how the EU directive 2004/35/EC on environmental liability impacts the Swedish administrative legal order. The thesis examines the directive through two main EU principles - the principle of good administration and the principle of procedural autonomy. The EU principle of good administration as a concept contains various procedural and substantive obligations that make up the subject for examination of the directive, both as regulated in the directive and as general principles of EU law. The directive is analyzed using a comparative method to determine to what extent the procedural and substantive principles of the directive impacts the Swedish administrative law, and weather or not the Swedish regulations comply with the EU principle of good administration.The results of the study shows that, althought there?s a general principle of national procedural autonomy, the EU principles of good administration do affect the Swedish administrative regulation in various aspects, through the implementaion of the directive on environmental liability as well as general principles of EU law.

Svenskars resemotiv till Egypten och Thailand

Purpose: My purpose of this study was to examine the factors that motivate Swedes to travel to Egypt and Thailand. To answer the question, I have used two questions.What are the factors that motivate Swedes to travel to Egypt and Thailand?What is the motive for Swedes choose to travel to destinations such as Egypt and Thailand?Method: The method I am using  is the qualitative method. The qualitative method has been processed through interviews of Swedish travelers, the Swedish travel agencies as well as Egypt and Thailand tourist agencies specializing in trips to Egypt and Thailand via phone and e-mail.Theory: The theory I am using are motivators and push-pull factors in achieving an understanding of the factors that influence choice for Swedes to travel to destinations such as Egypt and Thailand.Empiricism: The goal was to get a much more qualitative data from the response from the Swedish travel agencies, Egypt and Thailand tourist agency and Swedish travelers who have traveled to both of these destinations.Result: What I have come up with in my study is that the factors that motivate Swedish travelers to travel to Egypt and Thailand, is the warm climate, sun and sea, culture, variety, the cheap price situation and that there are activities for different age groups. This has led to the heat in both Egypt and Thailand has attracted Swedish travelers to travel to both destinations.

Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Introduction of heifers to an automatic milking system

Automatic milking systems (AMS) are part of a growing trend in Sweden and the number of milk-producing farms is decreasing rapidly. One main reason for the AMS is its ability to facilitate work for the farmer. The effects of introduction prior to calving have not been documented earlier and farmers are not in agreement, however they seldom see a problem with the introduction. The aim of this report is to find differences between two groups of heifers, where one group is trained i.e. introduced to the AMS before calving and the other group is introduced after calving.

Erfarenheter av utedrift med köttdjur i Sverige och Kanada :

Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.

Klimatanpassning och lantbruket i Värmland : Klimatförändringarnas upplevda effekter på lantbruket och olika aktörers åsikter om klimatanpassning

Climate change is a global and slow process that affects humans all over the world. Climate adaption within agriculture is important to reduce the risks that agricultures are exposed to because of climate change.  Through climate adaption you can improve the positive effects and take advantage of them optimally. How the climate change affects agricultures varies depending on regions and societies. The purposes of the study are to examine how different actors experience the impacts of climate change on the agriculture in Värmland.

Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Den kommunallagliga komedin : En uppsats om kommunala bolag; kompetensen, offentlighetsprincipen, bundenheten

The purpose of this essay is to examine and compare the news covering of Swedens three biggest cities (the metropolitan areas) and their surrounding areas with the covering of the rest of the country (the provincial areas) in two daily national newspapers, Aftonbladet and Dagens Nyheter. The aim has been to answer the following questions:- What amount of the news coverage in Aftonbladet and Dagens Nyheter concern the metropolitan areas compared to the provincial areas, and how do these two newspapers differ in the news covering of these areas?- Is there a difference in the news articles size and content, depending on weather they concern the metropolitan or the provincial areas?- How has the balance between news concerning metropolitan and provincial areas changed over the recent 20 years?The theories used in this study are News values, the media commercialization and Popular Journalism, and The Agenda Setting Theory. The method that has been used is a Quantitative Content Analysis.Despite the essays hypothesis, that the news coverage in the two newspapers would be dominated by material from the metropolitan areas, the result showed that a majority of the examined articles concern the provincial areas. It also showed that Aftonbladet has a bigger percentage of provincial news than Dagens Nyheter.
