The goal of the works described in this paper is to improve results produced by an object detector operating independently on each frame of a video document in order to generate a more robust index. Results of the object detector are ”smoothed” along the time dimension using a temporal window. For a given frame, we count the number of occurrences of each object in the previous and next frames, ...

In vivo dosimetry is important during radiotherapy to ensure the accuracy of the dose delivered to the treatment volume. A dosimeter should be characterized based on its application before it is used for in vivo dosimetry. In this study, we characterize a new MOSFET-based detector, the MOSkin detector, on surface for in vivo skin dosimetry. The advantages of the MOSkin detector are its water eq...

The radiative corrections of order a for the chargedand neutral-current neutrino-deuterium disintegration for energies relevant to the SNO experiment are evaluated. Particular attention is paid to the issue of the bremsstrahlung detection threshold. It is shown that the radiative corrections to the total cross section for the charged current reaction are independent of that threshold, as they m...

A strong theoretical candidate for weakly interacting massive particles (WIMPs) is the neutralino. The neutralino is the lightest supersymmetric particle (LSP), from supersymmetry (SUSY) theory, that would be formed in the early universe and subsequently cluster in galaxies with normal matter. This could account for the ~90% non-luminous mass inferred in our Galaxy from the motion of stars and ...

Fast and accurate energy calibration of photon counting spectral detectors (PCSDs) is essential for their biomedical applications to identify and characterize bio-components or contrast agents in tissues. Using the x-ray tube voltage as a reference for energy calibration is known to be an efficient method, but there has been no consideration in the energy calibration of non-convergent behavior ...

We propose a novel approach aimed at adaptively setting the threshold of the smoothed Teagor energy operator (STEO) detector to be used in extracellular recording of neural signals. Many types of spike detectors have been proposed all with their advantages and drawbacks. Most of the times there is a trade off between simplicity and performance. The performance of such systems is generally gauge...
