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.

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

Traffic accidents where wild animals are involved represents between 60 and 80 percent of all reported accidents, depending on location in Sweden. In a country like Sweden, with a lot of forest, there is always risk of a collision with a wild animal. Imagine if you, as a road user, had the possibility to receive warnings when the risk of an accident according to statistics is extra high.Wildlife Detection Network is a wildlife warning system with an information service, which makes the whole concept unique. When an animal is approaching the road, it is registered by sensors, and warning lights along the road are lit to inform drivers of the potential danger. In conclusion, this is a direct warning to all drivers on the road where the system is placed.When an animal is registered by the sensors, information containing time, date, weather circumstances and coordinates are sent to a database.

Detta kandidatarbete fokuserar på att undersöka aspekter som kan förstärka en användares upplevelse inom digitala spel. De aspekter som vi valt att fokusera på är användandet av Oculus Rift och Motion Capture då de tar upp viktiga punkter som Virtual Reality, närvaro och inlevelse i spel. Vi valde även att fokusera vår produktion mot skräckgenren då detta är ett område vi båda har stor passion för i diverse media. I vårt arbete har vi fått fram en hypotes om att spel som fokuserar på att lämna karaktären i ett tomt skal (ingen personlighet), lämnar en större chans för inlevelse hos spelaren då användarens egna känslor speglas på karaktären. Användandet av Oculus Rift och realistiska röresler via Motion Capture har en tendens att även stärka detta..

The purpose of this paper is to investigate the possibility of replacing data from highspeed filming (Qualisys motion capture) with data from Inertial Measurement Units (X-io technologies), when used to run a model of torso and pelvis in OpenSim. Qualisys motion capture data is used as the golden standard to validate the result visually and with Bland-Altman plots.In order to obtain comparable data experiments are conducted where both methods of collecting data are used simultaneously. Data from the IMU's then need to be processed in Matlab before it can be used to run the OpenSim modell. Several Matlab programs rotate the IMU data to a static reference frame, filter and integrate it, then create viritual markers that correspond to Qualisys' optical markers.The conclusion is that using IMU as a method for collecting data can replace Qualisys in some applications, but not in ones that require high precision. However, this paper only begins the examination of IMU's and there are most likely improvements to be made..

In 1929, the Scientific Crime Detection Laboratory was established in Chicago?the first of its kind in the United States. The purpose was to engage in practical use of scientific methods in the detection of crime. In 1930, the institute published its own periodical called The American Journal of Police Science. Applying the theory of boundary-work, this essay analyses how the novelty institute argued its legitimacy as a scientific establishment through the expansion of Police Science as a collective field of knowledge.

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.

Reliable methods to analyze food for the presence of almond are important ? not only for those allergic to almond, but also for monitoring the compliance with labelling regulations (EG directive 2003/89). Until now the Swedish National Food Administration has used methods like rocket immunoelectrophoresis and real-time PCR to detect almond in food. These methods are, however, not sensitive enough for protecting the most sensitive individuals. Therefore, the performance of a commercial ELISA kit was tested with regard to specificity/cross reactivity and limit of detection for almond both in solution and in different matrixes.The limit of quantitation was at least 3,1 ppm (mg/kg) in solution and similar concentrations were measured in bisquits and chocolate.

Alla människor behöver aktivera sig fysiskt och motionera på ett eller annat sätt. Men för att kunna motionera krävs det att motivation finns. Forskning har visat att motivation går att dela in i framförallt två former, det är inre motivation och yttre motivation. Den senare formen finns i fyra olika grader. Syftet med uppsatsen var att undersöka vad som upplevdes motivera till motion hos medlemmar på Friskis & Svettis.

Syftet med denna uppsats är att undersöka vad killar och tjejer, som går andra året pågymnasiet, har för attityd till Idrott och hälsa och i vilken utsträckning läraren påverkar attityder. Uppsatsen behandlar även om skolämnet Idrott och hälsa kan verka som ett verktyg för regelbunden motion. Undersökningen är genomförd på en skola där enkät och intervjuer ligger till grund för det empiriska materialet. Resultatet av studien visar att majoriteten av eleverna är positiva till ämnet samt att läraren har en stor inverkan för vilken attityd eleverna har till ämnet. Ett visst könsmönster går att urskilja när det gäller lektionsinnehållet, trots att detta inte efterfrågades av oss i enkäten.

Många faktorer har påvisats påverka individers hälsa. I denna studie undersöktes huruvida motion, Kasam och socialt stöd har betydelse för välbefinnandet i form av uppskattad hälsa, upplevd stress-energinivå och rapporterad sjukskrivning. Även köns- och ålderskillnader studerades. En enkät med frågor om sjukskrivning, motion, upplevd hälsa, upplevd stress-energi, Kasam och socialt stöd delades ut till 113 deltagare från tre olika arbetsplatser. Resultaten visade att Kasam hade positiva samband med hälsa, stress-energi och socialt stöd.
