A motion detection and tracking algorithm for human and car activity surveillance is presented and evaluated by using the Pets’2000 test sequence. Proposed approach uses a temporal fusion strategy by using the history of events in order to improve instantaneous decisions. Normalized indicators updated at each frame summarize history of specific events. For the motion detection stage a fast upda...

Degree of silvering (colouration) is often used as an index of the degree of srnoltification in salmonids. To judge the reliability of silvering a s an indicator of migratory readiness, we examined the silvering of wild coho salmon, Oncorhynchus kisutch, smolts upon entry into the Carnation Creek, British Columbia, estuary. Silvering of migrants was greater in larger fish and increased over the...

We show a general connection between the reduced-fidelity susceptibility and quantum phase transitions, and derive an explicit expression of the reduced-fidelity susceptibility for the one-dimensional spin-1/2 dimerized Heisenberg chain, which has both SU 2 and translational symmetries. We find that the reduced-fidelity susceptibility is directly related to the square of the second derivative o...

This paper deals with the digital complex representation of a DNA sequence and the analysis of existing correlations by wavelets. The symbolic DNA sequence is mapped into a nonlinear time series. By studying this time series the existence of fractal shapes and symmetries will be shown. At first step, the indicator matrix enables us to recognize some typical patterns of nucleotide distribution. ...

We introduce a new large-scale discriminative learning algorithm for machine translation that is capable of learning parameters in models with extremely sparse features. To ensure their reliable estimation and to prevent overfitting, we use a two-phase learning algorithm. First, the contribution of individual sparse features is estimated using large amounts of parallel data. Second, a small dev...

i_C = 0000100110001 I. ABSTRACT i_T = 0011010000000 Recent interest in Genomic Signal Processing has centered around studies on digital indicator sequences corresponding to the alphabet set {A, G, C, T}. Applications of Fourier transforms to such signals have yielded exon characterization peaks. Spectral analysis has also been used in finding genes, determining correct reading frames and in stu...

BACKGROUND Early identification of frailty is important for proactive primary care. Currently, however, there is no consensus on which measure to use. Therefore, we examined whether a Frailty Index (FI), based on ICPC-coded primary care data, and the Groningen Frailty Indicator (GFI) questionnaire identify the same older people as frail. METHODS We conducted a cross-sectional, observational s...

Errors in navigational instruments can significantly affect flight safety. Airspeed is a key piece of navigational data that depends on accurately measured air pressure, which in turn depends on accurately measured air temperature. Instead of measuring the outside air temperature in real time, cockpit instruments are preprogramed with standard air temperature values for different flight altitud...

The GERRI project materializes the Grenelle Environnement’s goals, of which the energy management of a territory is a facet. The aim is to forecast future energy production and consumption, bearing in mind economic and ecological indicators, and using a large number of interactions schemes between the involved parties. The originality of this paper is to present a new approach using the multi-a...
