This paper presents a methodology to assess the voltage stability status combined with optimal power flow technique using an instantaneous two-bus equivalent model of power system incorporating static var compensator (SVC) and thyristor controlled series compensator (TCSC) controllers. There by, a generalized global voltage stability indicator being developed has been applied to a robust practi...

A power system shifts to a state outside the stability boundary encountered by unstable limit cycles, at this point it will not return to the stable operating point. This resembles an increasing oscillatory behaviour in a nonlinear continuous time dynamic systems. Locating the unstable limit cycles and enhancing the stability margin is a difficult task. The effective devices for damping these o...

This study aims to determine the impact of covid-19 on profitability at PT. Matahari Department Store, Tbk. Profitability is ratio used measure level profit obtained from sales and investment. concerns are Return Assets (ROA), Equity (ROE), Gross Profit Margin (GPM), Operating (OPM) Net (NPM). The data secondary which includes financial reports for 2019 2020. analysis tools analyzing data, this...

Objective To evaluate the margins of resected specimen of oral squamous cell carcinoma (SCC) and to document the surgical margin (measured at the time of resection) and margins at the time of pathological examination (after immersion of the specimen in formalin). Methods Patients who were diagnosed and confirmed with squamous carcinoma of buccal mucosa were included in the study. Patients und...

The research we conducted to analyze the role of managers in improving financial performance at PT. Bank Rakyat Indonesia Tbk. 2017 2021. population this study is method used documents and literature. To measure here, researchers use ratio calculations, namely ROA (Return On Assets), ROE Equity), NIM (Net Interest Margin), BOPO. find out Assets) ratio, net profit after tax income required. As f...

This letter presents an online adaptive tuning technique for digitally controlled switched-mode power supplies (SMPS). The approach is based on continuous monitoring of the system crossover frequency and phase margin, followed by a multiinput–multi-output (MIMO) control loop that continuously and concurrently tunes the compensator parameters to meet crossover frequency and phase margin targets....

UNLABELLED A prospective study was lead in order to analyze the accuracy of an X-ray device settled in the operating room for margin assessment, when performing breast-conserving surgery. PATIENTS AND METHODS One hundred and seventy patients were included. All lesions were visible on the preoperative mammograms. An intraoperative X-ray of the lumpectomy specimen was systematically performed f...

In complex digital systems with high operating frequencies and large chip sizes, concurrent flip-flop and buffer insertion becomes inevitable for interconnect optimization. To preserve functional integrity, the pipeline constraint must be satisfied. Moreover, blockage avoidance, power reduction, and timing margin increase are also important issues. In this paper, we study the problem of blockag...

This paper gives an approach for improvement in the reduction in delay variation in a domino logic circuits and it also gives improved noise immunity to the circuit. The improvement in delay observed here is better in the proposed circuit and the noise immunity is also enhanced by a good margin. The simulation process here is done by using Cadence Virtuoso 65nm process technology at 27 o C oper...
