The effects of radiation damage in silicon photomultipliers (SiPMs) from gamma rays have been measured and compared with the produced by neutrons. Several types MPPCs Hamamatsu were exposed to neutrons at Solid State Gamma Ray Irradiation Facility (SSGRIF) Brookhaven National Lab Institute for Nuclear Research (Atomki) Debrecen, Hungary. ray exposures ranged 1 krad Mrad neutron 10$^8$ n/cm$^2$ 10$^{12}$ n/cm$^2$. main effect is an increase noise leakage current irradiated devices, similar...
The super Pioneering High Energy Nuclear Interaction eXperiment (sPHENIX) at the Relativistic Heavy Ion Collider (RHIC) will perform high precision measurements of jets and heavy flavor observables for a wide selection nuclear collision systems, elucidating microscopic nature strongly interacting matter ranging from nucleons to coupled quark-gluon plasma. A prototype sPHENIX calorimeter system was tested Fermilab Test Beam Facility as experiment T-1044 in spring 2016. electromagnetic (EMCal)...
When a hydrophilic intraocular lens material is immersed, its volume and mass start increase due to the diffusion of water (or isotonic saline solution) reaching quasi-equilibrium in time scale several hours. Here, we present combination atomic force confocal microscopy measure axial swelling speed such polymers distilled water. The measurements are used for experimental verification simplistic finite element model developed engineering applications COMSOL environment. calibrated with...
Abstract Machine-learning techniques allow to extract information from electroencephalographic (EEG) recordings of brain activity. By processing the measurement results a publicly available EEG dataset, we were able obtain that could be used train feedforward neural network classify two types volunteer activities with high efficiency.
Due to the acousto-optic (AO) effect, refractive index of an optical interaction medium is perturbed by acoustic wave induced in that builds up a phase grating will diffract incident light beam if condition constructive interference satisfied. All parameters, such as magnitude, period or can be controlled allows construction useful devices (modulators, switches, one multi-dimensional deflectors, spectrum analyzers, tunable filters, frequency shifters, etc.) The research and training...
The human body, including brain, generates biological signals. electroencephalogram, or EEG is the record of brain electric activity, measured on scalp. Nowadays acquisition these signals possible with affordable, consumer-grade devices. This paper proposes an approach to use Ultracortex Mark IV for data and explore variations in applying a convolutional neural network (CNN) when person moves his her fists feet. Eight electrodes were placed over head cortical electrical activity. As...
