Battery-cell hysteresis has crucial impact to battery-management system (BMS) performance. Improved hysteresis modeling accuracy can improve state-of-charge (SOC) estimation. This paper proposed using a linear least-squares method to identify a Preisach weight function and using the discrete Preisach model to estimate…
The production of low-carbon, low-alloy steel coils for oil-industry pipe is considered from a metal-physics perspective. The selection of cooling conditions for the steel sheet and coils after rolling is of particular importance here. Analysis of the accompanying structure formation is based on thermokinetic diagrams…
Abstract The effect of additives of sensitizing Zn(II) and Co(II) complexes with 5,15-(diethoxyphosphoryl)-10,20-diphenylporphyrin on the mobility of holes in thin poly3-hexylthiophene films is studied. The charge carrier mobility is measured using the CELIV and photo-CELIV methods. It is found that the sensitizing ad…
In this paper, the design of an ultra-low-power, low noise carbon nanotube field effect transistor (CNTFET) based transimpedance amplifier (TIA) is presented for an amperiometric based blood glucose monitoring system for wearable devices. The proposed cascode common source multistage transimpedance amplifier circuit i…
Disassembling nuclear warheads require the deployment of mixed oxide fuel (UO2+PuO2) for the utilization of Plutonium from warheads. For this purpose, the Nuclear Energy Agency has proposed a computational benchmark consisting of two VVER-1000 assemblies: LEU and MOX; to study their physics and the main differences be…
Assigning uncertainties to measurement results is primordial in a certification framework using fire benches as the cone calorimeter [1] developed by NIST [2]. Indeed, this process allows in the first place to validate the measurement method accuracy and in second place to provide proper results to compare obtained be…
A molecular scale simulation of the pattern formation process in electron beam lithography based on the stochastic approach is proposed. The formation of the initial resists structure is achieved by sequentially joining randomly selected monomers. The effects of electron exposure for positive-type resists are introduc…
The assessment of hydrogen release, distribution, and mitigation measures in the containment of a nuclear power plant is increasingly based on code calculations. These calculations require state-of-the-art experiments to benchmark the codes against them. Two of these experiments are presented in this paper. These expe…
We present metamaterial radome and conventional glass radome as superstrate of the microstrip patch antenna. Thin circular wire periodic array is proposed to obtain the characteristics of metamaterial in the radome. Reflection coefficient, gain and HPBW are obtained for metamaterial radome and conventional glass radom…
Conventional fiber filters for oil particle filtration have inadequate efficiency and exorbitant increase of pressure drop. Carbon nanotubes (CNTs) with nanoscale diameter have the potential in cooking fume filtration field. In this work, we synthesized the CNTs-filter through CVD method to grow CNTs on the Al 2 O 3 -…
Abstract Non-polar (11-20) GaN with low defect density can be achieved on sapphire by means of an overgrowth on a micro-rod template recently developed, or on a conventional 〈1-100〉-oriented stripe template. The overgrowth on stripes block BSFs in the nonpolar GaN more effectively, but it is difficult to obtain a flat…
In this work we present a novel method for the spatially resolved characterization of crystal defects in SiPMs. The contribution of crystal defects to the DCR is evaluated by exploiting the effect of “hot carrier luminescence” (HCL), which is light that is emitted during the Geiger mode operation of avalanche photodio…
Abstract Using the linearized version of the time dependent Gross–Pitaevskii equation, we calculate the dynamic response of a Bose–Einstein condensed gas to periodic density and particle perturbations. The zero temperature limit of the fluctuation—dissipation theorem is used to evaluate the corresponding quantum fluct…
Excitation transfer has long been of interest in biophysics, where electronic excitation is transferred from one location to another mediated by photon exchange. We are interested in the transfer of nuclear excitation mediated by phonon exchange, which according to our theoretical approach lies at the foundation of ma…
Electric motors have become one of the most important staples of industry. Electric motors' lifespan is highly affected by hotspot temperature of the motor during operation. Therefore, calculating and monitoring hotspot temperature can significantly increase motor's lifespan. However, obtaining motor's hotspot tempera…
A next-generation, adaptive, dynamic multi-pinhole system, AdaptiSPECT-C, dedicated to clinical brain SPECT imaging, is currently under development as part of a collaboration between the universities of Arizona and Massachusetts. It has been shown that accurate modeling of the system matrix is a key aspect of SPECT im…
In this paper, the frequency spectrum of a three- phase induction motor's stator current on a linear scale is investigated. The broken rotor bar, spatial and grid fed harmonics are taken into consideration. Since the fundamental component of the power supply is always the most powerful component, it makes the spectrum…
This paper presents an analytical thermal model of a synchronous reluctance motor (SynRMs) to predict the temperature of its different parts. For the analytical calculation, a lumped parameter thermal network (LPTN) is developed and analyzed. To validate the developed model, measurements are carried out on an experime…
Abstract— The process of the physical sputtering of the (001) surface of continuous and nanoporous crystalline silicon by 100- and 200-eV Ar ions is simulated using the molecular dynamics method. The features of the process in porous materials are revealed. The dependences of the sputtering yield on the fluence and en…
Abstract The study is devoted to the development of a microscope operating at a wavelength of 3.37 nm in the water window. A Schwarzschild lens with a multilayer coating is used as an image-forming objective lens. The microscope has a theoretical resolution of up to 13 nm and a field of view of 7.3–97.5 µm depending o…
