Various models using radiometric approach have been proposed to solve the problem of estimating the distance between a camera and an infrared emitter diode (IRED). They depend directly on the radiant intensity of the emitter, set by the IRED bias current. As is known, this current presents a drift with temperature, which will be transferred to the distance estimation method. This paper proposes...

Pulsed electron-electron double resonance (PELDOR) has proven to be a valuable tool to measure the distribution of long range distances in noncrystalline macromolecules. These experiments commonly use nitroxide spin labels as paramagnetic markers that are covalently attached to the macromolecule at specific positions. Unless these spin labels are flexible in such a manner that they exhibit an a...

In this study, the effect of cold temperature on the physical activity profiles of professional soccer players in official match-play was investigated. Computerised motion-analysis was used to analyse performance in 9 players (4 defenders and 5 midfielders) in 4 temperature ranges: ≤ 5°C (29 matches), 6-10°C (62 matches), 11-20°C (48 matches) and ≥ 21°C (27 matches). Performance was analysed pe...

In this paper we present an unsupervised colour-texture segmentation method. The novelty of this new approach relies on the definition of the interfeature distance map, which combines different textural properties, either those due to chromaticity variations or those due to intensity changes. The proposed framework works on a multi-channel representation that directly depends on the basic colou...

In this study, the effect of ultrasound irradiation on the flux recovery and fouling mitigation for the membranes made of the polysulfone by the phase inversion method were investigated. Two ultrasound irradiation regimes, including inside and outside the module, were chosen for this study. The experiments were conducted to investigate the effect of ultrasound irradiation on the membrane struct...

We study the fractal properties of the distances between consecutive primes. The distance sequence is found to be well described by a non-stationary exponential probability distribution. We propose an intensity-expansion method to treat this non-stationarity and we find that the statistics underlying the distance between consecutive primes is Gaussian and that, by transforming the distance sequ...

In this study, the effects of a prolonged period of fixture congestion (8 successive official matches in 26 days) on physical performance and injury risk and severity in a professional soccer team were investigated. Computerised motion-analysis was used to analyse the overall distance covered and that run at light- (0.0-11.0 km·h - 1); low- (11.1-14.0 km·h - 1); moderate- (14.1-19.7 km·h - 1) a...

In the study, a real time pedestrian tracking algortithm is presented using thermal infrared imagery. It makes use of the characteristics of pedestrian body regions in infrared images, which is based on a particle filter framework. The method constructs the regions of interest's (ROI) histogram representation in an intensity-distance projection space model, so as to hurdle the disadvantage of i...

The cognition test results of audio (A) and audio-visual (AV) effects on nine English emotions in a short sentence were compared to the physio-acoustic features of sound used for the cognition tests. Two groups of Japanese learners of English (JL2) and one group of English speakers (EL1) participated in these A and AV cognition tests. In the physioacoustic analyses we used F0 and intensity cont...
