This study has clarified aluminium gallium indium phosphide (AlGaInP) optical source integrated with fiber links and silicon avalanche photodetectors in optic systems. The output spectral power, rise time, signal frequency resonance for AlGaInP laser diode. diode power resonance/signal frequencies versus injection current ambient temperatures are sketched. silica doped germanium link pulse broa...

in this paper, we deal with the problem of adaptive coherent signal detection in gaussian interference (clutter plus noise) for surveillance pulse radars. some of the adaptive radar detectors exploit the ar model for clutter. most of these detectors have been obtained using the glr test. this test relies on the maximum likelihood estimation whose accuracy depends on the number of data. whereas,...

The light yield, the time resolution and efficiency of different types scintillating tiles with direct Silicon Photomultiplier readout instrumented a customised front-end electronics have been measured at Beam Test Facility Laboratori Nazionali di Frascati several test stands. results obtained configurations are presented. A order 300 ps, yield more than 230 photo-electrons, an better 99.8 $\%$...

Volatile Organic Compounds (VOCs) are largely used in many industries as solvents or chemical intermediates. Unfortunately, they include some components, present in the atmosphere, that can represent a risk factor for human health. They are also present as a contaminant or a by-product in many processes, i.e. in combustion gas stacks and groundwater clean-up systems. Benzene, in particular, sho...

introduction: during radiotherapy, high accuracy in the dose delivery is required because there is a strong  relationship between the absorbed dose, local tumor control and particularly the normal tissue damage. in  many institutions, in vivo dosimetry using diodes is performed to check the actual dose delivered. in general,  the uncertainty in the dose delivered should fall within  ± 5% of the...

X-ray direct detectors based on hybrid lead-halide perovskite have seen a dramatic increase of interest in the last years. A rush for achievement high performing devices drives scientific community. In this context, several photoconductor sensors employ functional layers to gain effect, but full comprehension mechanism is still lacking. Here nanoanalysis used, performed by simultaneous acquisit...

Observability of individual fluorescent molecules under a microscope has many applications in biology.1, 2 In particular, by grafting fluorophores to biomolecules, they can be tracked in real time in live cells for monitoring of their conformational changes and interactions with other molecules. In other words, singlemolecule imaging allows scientists to read the textbook of life pretty much as...
