Photovoltaic systems integrated to the grid have received considerable attention around the world. They can be connected to the electrical grid via galvanic isolation (transformer) or without it (transformerless). Despite making galvanic isolation, low frequency transformer increases size, cost and losses. On the other hand, transformerless PV systems increase the leakage current (common-mode c...
A novel domain for Index Modulation (IM) named “Filter Domain” is proposed. This new generalizes many existing modulations and IM domains. In addition, a scheme Shape Modulation” (FSIM) FSIM allows higher Spectral Efficiency (SE) gain than the time frequency dimensions in Single-Input Single-Output (SISO) systems. system, bit-stream mapped using an Amplitude Phase (APM) as QAM or PSK, index of ...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
—Index modulation, where information bits are conveyed through antenna indices (spatial modulation) and subcar-rier indices (subcarrier index modulation) in addition to information bits conveyed through conventional modulation symbols, is getting increased research attention. In this paper, we introduce precoder index modulation, where information bits are conveyed through the choice of a preco...
