Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.

A lot of various substances can be detected by dogs, as oestrous in cows, endangered species or non-biological substances like accelerants, narcotics, explosives, mines and pollutions and biological substances like identity (suspects), cancer (breast, lung, colorectal and bladder cancer), human remains (cadaver), bacteria and mould in buildings. The dogs are trained using non-scientific methods and not much research in detection training exists. This is a review of different types of dog detection, with focus on new research..

This thesis is commissioned by the Swedish electricity trading company GodEl with the purpose of evaluate solar electricity in multi-family buildings in the Stockholm region. The prices of solar panels have dropped recently due to the advances in technology, but the installation rate in Sweden remains low. It is therefore interesting to study the  profitability of solar electricity today, and if it is profitable enough to install based on profitability alone and not simply due to environmental considerations. Therefore this thesis first studies the profitability of solar panels based on a simulation of electricity production and consumption for multi-family buildings this region. The study concludes that solar electricity can be profitable in the Stockholm region under certain conditions; all of which have to be favourable for profitable solar electricity.The thesis also studies the opinion of the company's costumers concerning solar electricity.

This report is the result of an evaluation of a project, conducted by five regional libraries. Through a training course the project should inspire small and medium sized enterprises to use modern information technology and Internet when searching for information. To evaluate the project, qualitative interviews were conducted with five librarians and quantitative questionnaires were distributed to all the course participants. The evaluation shows that the project goals were met, apart from the number of course participants, which was much lower than anticipated. It also shows that the project resulted in an increase in information technology and competence at the libraries, and that the course participants profit from their increased knowledge in their daily work..

The purpose of this study is to investigate whether it is possible for SCA to update their stand register with use of digital aerial photos photographed with a Zeiss/Intergraph DMC. ?Updating? in this study implies the delineation of stands and estimating stand variables such as average stand height, volume density, stand volume, and tree species composition in order to identify stands which can be of current interest for thinning. The study also includes how the aerial photo material and experience of the interpreter can influence the quality of the interpreted variables. The aerial photo interpretations were made by both experienced and inexperienced interpreters.

På uppdrag av Kliniskt Tränings- och Simulerinscentrum (KTC) kom författarna till denna studie i kontakt med ämnet simulationsträning. Simulationsträning introducerades under 50-talet i den medicinska världen. Sedan dess har det gjorts många framsteg och förbättringar på området, i takt med att kraven ökar på sjuksköterskans arbetsuppgifter. Syftet med den här studien var att studera effekter av simulationsträning. Studien baseras på tio vetenskapliga artiklar vilka behandlar simulationsträning och dess effekter.

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Horses respond individually to challenges, and the possibility to use these reactions to evaluate equine temperament with an objective instrument would have several advantages. Horse welfare could be improved by making it possible to find individuals best suited for a specific use, and understanding of the development of abnormal behaviours, such as stereotypies, could be increased. Management routines and training could be adjusted tosuit each individual horse and it could facilitate the selection of individuals appropriate for breeding. There are also economic implications, as horse buyers consider temperament important and after evaluating temperament, money can be spent solely on specific horses with all the right qualities. During the last decade, many attempts have been made to measure different aspects of temperament in horses, and the first aim of this project was to look at these studies and see which methods were used and which temperamental characteristics they measured.

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

Studiens preciserade problem består av att undersöka vilka effekter Aggession Replacement Training (ART-metoden) ger, och om hur pedagoger kan möta, förebygga och hantera konflikter och aggressioner i skolan med hjälp av metoden. Genom litteratur, intervjuer, samt genom inhämtad kunskap om ART-metoden, redogör vi för hur pedagoger i den utvalda undersökningsgruppen kan arbeta förebyggande och hantera uppkomna konflikter. Slutsatsen vi kom fram till är, att man måste arbeta regelbundet med ART-metoden och ha tålamod om inte effekterna är omedelbart synliga. Pedagogerna skall arbeta med förebyggande åtgärder för att stärka individen och förbättra det psykosociala klimatet i gruppen och se de små men betydelsefulla förändringarna - effekterna..

Miljöbron is a non-profit organization; their main purpose is to merge companies and students into different environmental projects. The projects can be an assignment, practical vocational training or degree thesis. Miljöbron is expanding and the demand from students and companies is rapidly growing. Because of the expansion, a large amount of information needs to be stored and managed in a structured database. Also the need of a interface that is structured and easy to use when managing information and Miljöbron?s statistics, for Miljöbron?s staff.

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

Body awareness is a term that refers to a person´s perception and knowledge about his or her body. It includes proportion, size, weight, contour and image of ones body. The Ben- Tovim Walker Body Attitudes Questionnaire (BAQ) contains 44 questions concerning the different aspects of body awareness: Feeling fat, Body disparagement, Strength and fitness, Salience of weight, Attractiveness and Lower body fatness. The purpose of this study was to investigate body awareness among men in military recruit training. BAQ was distributed to fifty recruits for military service in Boden.

Aim: The aim of this study was to investigate how women who have incurred ACL injury for more than 10 years ago, feel that the injury affects them today.Method: A qualitative semi-structured interview survey with five women who 10- 28 years ago incurred the anterior cruciate ligament injuries when playing handball or soccer has been performed. The study has been inspired by a phenomenological concept of science, mainly by life-world concept. Data were analyzed using qualitative content analysis.Main result: Some informants have experienced severe loss of physical ability in both daily living situations and in training, while others did not appreciably felt impacted in daily living and experienced great opportunities for physical activity. Limitations which emerged were restrictions in movement, joint stiffness, pain, swelling, and crepitations that led to the loss of physical ability. One respondent had been diagnosed with advanced osteoarthritis.

In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.
