This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation. Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory …

X-ray fluorescence (XRF) detection of heavy metals is a cost- and time-effective method for investigation of polluted areas. Compared to laboratory analysis, XRF analysis is limited by high detection limits and uncertainties in some situations. Preparation of samples is known to …
a review of the scientific literture
… 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.
… act as primary pathogens. The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria. In the experimental procedure the …
The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model …
… L-band Synthetic Aperture Radar (ALOS PALSAR) is investigated for clear-cut detection in boreal forests in northern Sweden (Lat. 64°14? N, Long. 19°50? E). Strong forest/non-forest contrast and temporal consistency were found for the Fine Beam Dual HV-polarized backscatter …
… 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 …

… CV AB, Tekniskt centrum, Södertälje. Examensarbetet behandlar Side Blind Spot Detection och har resulterat i ett prototypsystem som detekterar objekt i döda vinklarna på sidorna av en lastbil. Systemet är ett aktivt säkerhetssystem som syftar till att förhindra olyckor och ge …
… farmers using artificial insemination (AI) are dependent on effective oestrus detection. In Sweden, AI is used for a majority of all dairy cows and oestrus synchronisation with hormones is not allowed. There are reports of declining ability to express oestrus with higher levels …
… in the analysis of Cu, Fe and Na. The focus of the project was to find the detection limits for each metal, study the variation and to see if it is possible to analyze these water samples with this technique. The concentrations of the calibration solutions is between 1-10 µg/l …
Snabbt nog?
… av ett flertal gatewayenheter kan det, med hjälp av Neighbor Unreachability Detection, ske automatisk övergång till en ny gatewayenhet utifall att den aktiva skulle gå ur funktion. Innan IPv6 har man varit tvungen att förlita sig på externa lösningar för att uppnå denna …
… of wheat in colder climates. This project aims at developing methods for detection,quantification and identification of known and unknown fungi present in Swedish cereals during 2009-2011. Theproject was carried out using two previously published methods, TMAV and MGB, which …
… of lymphomas and mammary tumors immunohistochemically. Immunohistochemical detection of the proliferation marker TK1 may theoretically aid routine examination of histological samples postsurgically. Analysis of TK1 in tissue samples may be of use to establish minimal residual …
… health and economy with its endemic and sometimes pandemic spread. Rapid detection of Influenza viruses enables antiviral use and can bring financial savings. It is also essential for the global surveillance of prevalent Influenza strains. RT-PCR is considered the most specific …
metodutveckling och validering
… (EOG) data was used to develop, adjust and validate a method for drowsiness detection in drivers. The drowsiness detection was based on changes in blink behaviour and classification was made on a four graded scale. The purpose was to detect early signs of drowsiness in order to …
