<p>This paper proposes the grid application of modified three-phase topology of Modular Multilevel Converter (MMC) using finite-control-set predictive control. This topology has reduced number of switch counts compared to the conventional MMC, eliminates the problem of circulating current and having higher efficiency. A single dc source is required to produce sinusoidal outputs. The number of sub-modules (SMs) in this topology is half of the SMs required in case of MMC, in addition to a single H-bride circuit per phase. The finite-control-set predictive current control scheme for the grid connected dc source through the Hybrid Modular Multilevel Converter (HMMC). This controller controls the desired real and reactive power demand of the grid instantaneously. The simulation study of a three phase grid connected system has been done in Matlab/Simulink and the results are provided for the different real and reactive power demands, to validate the concepts.</p>

This study offers a critical analysis of ShyamBenegal’sHindi language-based teledrama series AmaravathikiKathayen utilizing Mikhail Bakhtin’s theories of dialogism, heteroglossia, and polyphony. It is common sense to think that Bakhtin, the philosopher of dialogism, would be sympathetic to the drama form in which dialogues are the most natural mode of expression. Instead, Bakhtin argues that the monological selection of languages in drama does not allow the dialogic interaction of different registers. Second, drama, for upholding its unity of plot, cannot allow its characters to abide by a truly multi-level dialogic engagement. However, this act is especially performed in the novel by the inter-animation of the narrator’s all-encompassing language and the language of the characters. Against this, this study brings to the fore the historical premisesof Bakhtin’s reservations against the dramatic form. Recognizing the merits of Bakhtin’s philosophy of literature and language, two episodes from AmaravathikiKathayen, a Hindi language-based teledrama series,areanalyzedto place them before the global audiences as well as to ascertain the relevance of Bakhtin’s poetics across the genres. Above all, a return to dialogism as a critical inquiry is important to promote the values of plurality, dialogue, and peaceful co-existence.

This paper lays out the current work and discuss about the virtual lab simulation of rolling element bearing defects either the inward or external race or on the moving component surface that are visually undetectable. The present experiment proposed in this paper teaches how a bearings fault in the system is monitored based on the vibration analysis. Bearing failures have incredible effect on industry and economy. Bearing disappointment is frequently ascribed to be one of the significant reasons for breakdown in mechanical pivoting machines work at low and high velocity. Bearing vibration can be useful in the detection of various faults and also helps in processing of effects of the defects present in the different components of the bearing. The vibrations created by a solitary point abandon on different parts of the bearing under steady spiral burden are anticipated by utilizing a hypothetical model. The model incorporates variety in the reaction because of the impact of bearing measurements, turning recurrence dispersion of burden.
