This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

My essay deals with a problem in our society which, in my opinion, has been neglected. Even today in 2011, the quality of schools and preschools is extremely varied. This has been a problem for a long time and not nearly enough attention has been paid to it.In my essay I have tried to understand what it is that causes these differences in quality between preschools. With help from literature and research studies I have examined what quality in preschool really means.My starting point is an account of my own experience at the preschool where I currently work and a description of a study visit I made to another preschool which operates in a very different way to the one where I work. I wanted to investigate what the consequences are for children who grow up attending preschools of different quality.

In the year of 2011, the new CEO of AB Volvo announced a major reorganization. This reorganization was a contributing factor to the start-up of this thesis.Volvo Group Logistics Services (VGLS) is Volvo Group?s global logistics partner, which designs, manages and optimizes all of the group's incoming and outgoing logistics flows. With the reorganization, VGLS started a project regarding responsibilities around railway flows. Within the project a demand to collect logistics requirements occurred.

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it?s in everybody?s interest to reduce the energy consumption and thus reduce the emission of carbon dioxide. An additional incentive to reduce the energy consumption is the substantial increase of the energy price since the deregulation of the electricity market in 1996.In this study the techniques that exist to build multi-storey residential buildings with high energy performance will be investigated. Further the study intends to investigate the optimal energy performance from a real estate economic perspective.In order to investigate the optimal energy performance a model has been created with the parameters investment cost, rental revenues, operation and maintenance cost, discount rate and investment horizon.The result shows a relationship between a high investment cost and a high energy performance for newly constructed multi-storey residential buildings.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

Corporate Social Responsibility (CSR) is a topic that is becoming increasingly important in today's society. CSR is a concept whereby companies voluntarily integrate social and environmental concerns both in their business but also in interaction with their stakeholders. The society of today sets high expectations for how companies take their social responsibilities, especially in industries where the risks to individuals and the environment are high. In this study, we tried to answer the following questions; what kind of responsibility do companies in the plastics and chemicals industry claim to take and why might this be due? What differences exist between the investigated companies in the industry and what may these differences be rooted in? The purpose of this study was to obtain an understanding of the interest in working on sustainability in the plastics and chemicals industry.

The objective of this thesis was to get more knowledge about how to design a dairy farm reducing the working hours and the work tasks whit high work load. I will try to reduce the working hours and the tasks whit high work load on my own farm witch I am about inherit. Today, the old stanchion barn has room for about 60 cows and 74 young cattle and need two men to run it every day. The total acre is 188 hectare, 100 hectare forest, 65 hectare farmlands and 23 hectare natural pasture. I have studied two solutions. In the first solution, I will use my old barn for young cattle and build a new barn for the cows.

Begreppet lågkolhydratkost myntades för första gången 1921 och efter det har en rad olika varianter av kosten uppmärksammats. En svensk variant som har fått stor genomslagskraft är Low Carb High Fat (LCHF). Där förespråkas, i motsats till de nuvarande svenska näringsrekommendationerna, en hög andel fett, gärna mättat, samt en låg andel kolhydrater. Viktminskning har visat sig fungera effektivt med LCHF och lågkolhydratkost. Det finns även undersökningar på att kosten har en positiv inverkan på blodfetter, blodtryck, diabetes typ 2, humör och mättnad, men dessa resultat är fortfarande tvetydiga.

This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

Background: 2007 there was 42 000 fall related accidents in Sweden and they are expected to increase the next few years. Fall among elders results in both increasing economically costs and suffering, but they can be prevented. For example has physical exercise shown an increasing effect on the risk for falls. Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

Lerbodaälven is a river in the municipality of Kil which, due to high phosphorus content is not meeting the requirements for good ecological status according to the Water Framework Directive. The purpose of this report is to investigate the causes for the high content of phosphorus that has been measured in Lerbodaälven between 1995-2010. Four questions will be answered in this report. 1. Does the sewage treatment work affect the phosphorus level in Lerbodaälven? The result from the time series analysis shows that the sewage treatment works have a small impact on the phosphorus level in Lerbodaälven.

This work is about the expanded conception of text and takes off in the use of this expression in the high school curriculum. The work begins with a theory chapter, where a few different definitions of text are the basis for reasoning about factors which can have contributed to an expansion of the conception. Hereby other important expressions, related to the expanded conception of text, as hypertext, multimedia and intermediality, are brought up. Further, is examined empirically how the expanded conception of text is interpreted, rhetorically and practically, by a few teachers in the High School. Finally, covered scientist?s theories are discussed and compared with the concluded empiric data.The study shows however, that the expanded conception of text in the curriculum has not become a conception for the teachers who were interviewed.
