Traditional Cu ( InGa ) Se2 (CIGS) solar cells consist of an Mo bottom contact, p-type CIGS absorber layer, n-type CdS buffer and ZnO window layer including a very thin intrinsic topped with Al-doped transparent conducting oxide that was simulated by Silvaco technology computer aided design simulator. The thickness the layers other parameters were limited to values reported in literature. simulator examined affirm its functionality, step-by-step method applied optimize baseline structure....
Increase in people participation Sport for all has always been considered by policy makers. This paper aims to present a model institutionalize sport of Iran. For this purpose, researchers referred the experts Iran and collected data from them through deep interviews. Then, resulted twenty-nine interviews were encoded analyzed grounded theory method. The results codes classification showed sixteen components at three contextual, organizational, behavioral levels. According model, it can be...
Lyapunov exponent (LE) is a mathematical-based analysis tool to assess the stability of dynamical systems and this can be done by two approaches: model-free approach model-based approach. In paper, employed as an indicator for power systems. The maximum (MLE) used investigate effects increasing load on region system where positive (negative) value MLE means instability (stability). Also, LEs are effect presence renewable energy Simulation results presented single-machine fixed-speed...
Development is an important issue to which the major part of people’s efforts has been allocated. Nowadays, it perceived that development could have undesirable results in addition its advantageous outcomes. These are emerged different themes such as social, environmental and cultural aspects. As a result, ones who work on plans try predict prevent unwanted projects order reach sustainable development. Due this fact, social impact assessment (SIA) considered by decision makers. SIA...
Massive multiple-input multiple-output is a promising technology in future communication networks where large number of antennas are used. It provides huge advantages to the systems data rate, quality services, energy efficiency, and spectral efficiency. Linear detection algorithms can achieve near-optimal performance large-scale MIMO systems, due asymptotic orthogonal channel property. But, linear detectors degrades when transmit close receive (loaded scenario). Therefore, this paper...
Direction of arrival (DOA) estimation acoustic signals has been studied extensively by many researchers. Improving the performance DOA methods is a hot topic in array signal processing. In this study, an application coherence factor, which widely applied medical ultrasound imaging, extended to wideband signals. The advantage applying different factors tracking sources illustrated cross correlation-based estimation. order evaluate proposed method both simulated data and narrowband recorded...
Simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) is a cutting-edge concept for the sixth-generation (6G) wireless networks. In this letter, we propose novel system that incorporates STAR-RIS with simultaneous information power transfer (SWIPT) using rate splitting multiple access (RSMA). The proposed facilitates communication from multi-antenna base station (BS) to single-antenna users in downlink transmission. BS concurrently sends energy signals...
Measurements of B-mode polarization in the CMB sourced from primordial gravitational waves would provide information on energy scale inflation and its potential form. To achieve these goals, one must carefully characterize Galactic foregrounds, which can be distinguished by conducting measurements at multiple frequencies. BICEP Array is latest-generation multi-frequency instrument BICEP/Keck program, specifically targets degree-scale B-modes CMB. In final configuration, this telescope will...
