De tropiska regnskogarna är några av de mest komplexa och artrikaste ekosystemen i Världen. Stora delar av de naturliga Dipterocarpa regnskogarna har under de senaste decennierna försvunnit helt p.g.a. ändrad markanvändning (oftast jordbruk), eller degraderats till sekundära regnskogar p.g.a. torka, bränder och selektiva avverkningar. Det finns därför behov av rehabilitering för att få tillbaka artrikedomen i skogarna. Syftet med det här kandidatarbetet är att titta på hur överlevnaden hos plantor i ett rehabiliteringsprojekt i en sekundär regnskog påverkas av olika ståndortsfaktorer.

AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.

Common species of freshwater mussels may, like the freshwater pearl mussel (Margaritifera margaritifera) have a drastic decline in number and there is several reasons, like sedimentation, a decline of host fishes, introduction of alien species, nutrition leakages from agriculture and pollutants of medic drugs and poison. Ann Gustavsson made in the year of 2007 a study over rejuventation of freshwater great mussels in nine watersystems and considered that the rejuventation within the populations were all along the line poor. This study orients from her work and points to determine if there is a connection between the poor juventation and pollution of nitrogen and phosphorous from industries and private sanitations. The study was performed with the software program ArcGIS9.2 to take out drainage areas for the concerned habitats and contact was made with the concerned authoritys. When it comes to supervision of private sanitations is it the countys and for industries is it the county administrative board.

Researchers today anticipate that in the near future, the majority of the owners of a smartphone will use it as a wallet, i.e. for contactless payment. The technology that enables contactless payment today is ?Near Field Communication? (NFC), which is increasingly embedded in smartphones. Applications like mobile payment between a phone and a terminal use NFC.

However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

BackgroundIncreased prevalence of obesity in children- and young adults and risk for diseases related to obesity will increase the burden on medical care. It is important to identify early risk factors that can be noticed by nurses in the daily work.AimThe aim was to investigate whether children- and young adults themselves perceive overweight as a problem and if there was a difference in the measured activity levels between overweight children- and young adults in families with different socio-economic family status.Method descriptionExisting survey from the Obesity Centre at the Akademiska Sjukhuset were examined together with the results from an accelerometer, where children- and young adults activity was recorded, compared to their perception of how active they were. The results were compared using a statistical software program and compiled with descriptive and non-parametric statistics.ResultsThe results do suggest that the majority of children- and young adults experiencing excessive weight have a problem in their everyday lives. Nearly half overestimate themselves as more active than what the actual measurements with accelerometer demonstrated. Much time is spent in front of the TV and computers.

The snow leopard (Panthera uncia) is an elusive felid, native to the mountains in central Asia. Basic knowledge about the snow leopards? ecology has long been lacking but is advancing with the help of the GPS-technology. GPS cluster analysis can provide insight in the diet and prey selection of elusive predators, such as the snow leopard. Acceleration data from GPS collars can be used to study animal behavior but the two have never been combined to gain more detailed information of the feeding behavior of large carnivores.

Sammanfattning Fel i programvara (buggar) kostar ofantliga summor varje år. I detta arbete presenteras en metod där programexekveringsmiljön utan vare sig programmerarens eller användarens inblandning utförligt kan rapportera och dölja effekterna av en avsevärd andel buggar. Genom att kompilatorn eller tolken tillåter att en och samma procedur implementeras hur många gånger som helst införs ett helt automatiskt stöd för N-Version Programming (NVP) omedelbart i programspråket. Tekniken gör programvaran feltolerant och blir ett komplement till kostsam och ofta bristfällig testning. En tolk utvecklades för ett programspråk som tillåter multipla definitioner av procedurer. Därmed har det inbyggt stöd för feltolerans genom redundans på procedurnivå. Ett experiment genomfördes där nio programmerare oberoende av varandra implementerade 12 utförligt specificerade procedurer.

3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.

It always has been a need for the abiltiy to create color proofs. When an error occurs late in the production process, itis allways complicated and difficult to correct the error. In this project, digital proofs been made and discussions havebeen held with several people in the printing industry, in order to examine how well excisting digital proofs, meet thedemand of the market. And how close the digital proofs can come to the actual printsheat from the press. The study hasbeen shown that the one thing that has had the most influence on the outcome for the quality of a digital proof, is theprintshop operator?s knowledge about color management and proofing systems.

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to  improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.

The goal of this thesis is to investigate the W3C Geolocation API from a developer?s perspective, focused on whether it makes development of location-based applications more accessible to developers. This has been investigated by looking at available ways to locate, possible uses, the functionality offered, the necessary level of prior knowledge needed for a developer and requirements on developer tools. This has been achieved through studies in relevant areas, a thorough introduction to W3C Geolocation API functionality, and by using the API to develop two different location-based applications as a demonstration. Testing of applications, on different platforms and in different environments, in conjunction with investigation of the rest of the material has shown that W3C Geolocation API in many ways actually makes development of location-based applications more accessible for developers. The API also provides fully adequate functionality and quality to meet the requirements for development of both simple and very advanced location-based applications. Målet med denna uppsats är att undersöka W3C Geolocation API ur ett utvecklarperspektiv, fokuserat på om den gör utveckling av positionsbaserade applikationer mer tillgänglig för utvecklare.
