Reversible operation of a microtubular solid oxide fuel cell SOFC with high electrochemical efficiency is reported. These devices can ideally produce hydrogen from electricity and steam solid oxide electrolyser SOE and then use the stored hydrogen to generate electricity and heat SOFC , acting as a storage device for the electrical energy. A fuel-electrode-supported Ni–yttriastabilized zirconia...

Over the past years, new memory technologies such as RRAM, STT-MRAM, and PCM have emerged. These technologies employ devices located within the metal layers of the chip, which are relatively fast, dense, and power efficient and can be considered as 'memristors'. To date, research in these devices has primarily focused on memristors as flash, DRAM, and SRAM replacement. In this presentation, we ...

Pitch period and amplitude perturbations are widely used parameters to discriminate normal and voice disorder speech. Instantaneous pitch period and amplitude of glottal vibrations directly from the speech waveform may not give an accurate estimation of jitter and shimmer. In this paper, the significance of epochs (glottal closure instants) and strength of excitation (SoE) derived from the zero...

In the current economic context, enterprises are struggling to obtain competitive advantages on the market, by exploiting the opportunities offered by information technology. The research in this paper aims to encourage the use of modern approaches in order to increase enterprise agility, through the transition to Service-Oriented Enterprise (SOE). The proposed solution is based on reaching a s...

A novel HCPV nonimaging concentrator concept with high concentration (>500x) is presented. It uses the combination of a commercial concentration GaInP/GaInAs/Ge 3J cell and a concentration Back-Point-Contact (BPC) concentration silicon cell for efficient spectral utilization, and external confinement techniques for recovering the 3J cell’s reflection. The primary optical element (POE) is a flat...

Following previous research on management efficiency of state-owned enterprises (SOEs) in Lithuania, this paper continues discussion via extension the observed time period seeking to continuously analyze impact corporate governance principles effectiveness Lithuanian SOEs.For purpose study, elements established initial reform SOEs Lithuania are used as key dependent variables measure and quanti...

Abstract The paper pursues a mixed methods approach of conducting both quantitative and qualitative content analysis corporate social responsibility (CSR) reports in two types Chinese companies: State-owned (SOE) non-state-owned (non-SOE) enterprises. Quantitative revealed overall homogeneity CSR reporting among SOEs non-SOEs China, which can be explained by coercive isomorphism on national sca...

We investigate the impact and mechanism of industrial policy on corporate investment efficiency. Using micro-level data A-share listed firms China’s stock market from 2001–2020, we examine whether policies have different effects state-owned enterprises (SOEs) non-state-owned (non-SOEs). Moreover, identify specific followers to further illustrate The empirical results show that promote investmen...
