Passive acoustic diver detection
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.
Låg, medel eller hög kvalitet i förskolan : En studie om hur och varför kvalitèn skiljer sig mellan förskolor
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.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell
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.
European Union Politics ? en tidskrift och dess invisible college
Author Cocitation Analysis (ACA), multidimensional scaling (MDS) and Social Network Analysis (SNA), has been used to analyze and visualize the invisible college of the journal European Union Politics. The concept invisible college was first introduced in the fifteenth century, through the creation of the ?the Royal Society of London?, and it was reintroduced in the 1960:ies and the 1970:ies by scholars such as Price and Crane. It is said to have been interpreted in as many ways as there are authors who have used it. Here it has been used synonymously with the term citation network.
En kostnadsanalys av energieffektiva flerbostadshus
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.
Etiologi och patogenes för benign prostatahyperplasi hos hund
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.
Läs- och skrivinlärning : Om elevers läs- och skrivinlärning under de första åren
In contemporary Sweden political participation among foreign-born Swedes is viewed as low and it is well known that foreign-born individuals do not use their voting rights to the same extent as the general population. At the same time there are numerous ethnic associations around the country who work with various activities involving political, democratic and integration issues. This study aims to study how four members of a Somali association regard, relate to and work with politics, democracy and integration. The study is based on these four people, but also on their relationship with authorities and other agencies in the community. The conclusion of this study shows in brief that the desire to participate politically is great, but that democracy and politics is accessible to all, depending on the level of language skills and what political knowledge the individual has.
Automatisk viktkontroll av glascontainer
This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.
CSR i plast- och kemibranschen
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.
Systematiskt arbete för att hantera osäkerheter vid mätning : vid Q-Med AB i Uppsala
This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.
Vi i individualismens samhälle? : En studie över fackföreningsorganisationens ställning i det individualistiska samhället
In Sweden, the labour movement historically had influenced both society and politics. In recent times, it is considered a change in society with a stronger employer party while the unions weakened by reduced unionisation. This study aims to highlight the presence of individualistic and collectivistic approaches to the labour market in relation to union density. The different approaches are investigated in the labour market by means of a quantitative survey. The study's survey items are workers in the timber industry.

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.
Frisk med fett? Upplevda hälsoeffekter med Low Carb High Fat
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.
