In this paper a charging kinetics of cross-linked polyethylene (XLPE) under electronic beam irradiation in scanning electron microscope (SEM) is quantified by the evaluation of trapped charge. The effect of thermal aging at different temperatures ranged from 80°C to 140°C is highlighted and analyzed. The variation of charging process of XLPE is monitored with measuring the influence current, leading...
Total ionizing dose effects in analog configurable application specific integrated circuits such as analog gate array and programmable analog gate array were analyzed. Dominant failure mechanisms and potentially radiation sensitive internal units were determined within −60…+125C temperature range. +125C area corresponds to the minimal radiation hardness.

This work aims to analyze the performance of grid-connected photovoltaic (PV) system installed in the Saharan area of south Algeria (Adrar) in four different days, each one from different season of the year 2015. The results showed that temperature and irradiance play important role in system performance; the performance ratio and the system efficiency depend heavily on the temperature and drop from...
The paper deals with the transformation of the existing bus shelters for the public transport into smart systems equipped with Wi-Fi stations, USB chargers and Air Quality Control Station.

Single-event effects and total ionizing-dose testing was performed on a flash NAND device.

The analysis indicates that many typical error correction architectures may...

We provide a brief discussion of the basic enhancement mode gallium nitride (GaN) power FET device structure and its performance and then report the results of destructive single-event effects (SEE) testing of the Intersil ISL70023SEH and ISL70024SEH GaN power transistors. We include a discussion of a conservative safe operating area (SOA) specification for both devices.
The effect of post irradiation annealing on the following radiation degradation rate of bipolar integrated circuit parameters was estimated. The degradation rate increases significantly during the irradiation in comparison with the irradiation before the annealing.
Plasmonic nano-cavities have the ability to confine light in sub-wavelength gaps. The smallest possible plasmonic nano-cavities are achieved with the nanoparticle on mirror (NPoM) configuration [1], where a flat metal substrate is separated from a nanoparticle with a thin molecular spacer, typically of 1–1.5nm thick (Fig.1a). The massive field enhancement facilitates the strong-coupling of a single...
In superconducting films, the dissipative flux flow state plays a crucial role in the stability of those devices that operate under bias current whose value is very close to the critical current value, such as superconducting electronics and superconducting single particle/photon detectors. Therefore, we study the voltage stability versus electrical current transport by proper current-voltage measurement...

The paper deals with the modeling of small photovoltaic (PV) system output power. The system operator needs information for the expected energy yield of the system to preserve the balance in the grid. Thus, the estimation of this energy yield has a significant role. The present study is based on Durisch's model. In order to optimize the power output prediction of the studied aSi thin film, PV modules...
