The performance of the state estimation (SE) depends on the accuracy of the received measured data, as well as the parameter data of the power system. In this paper, a new algorithm is proposed for the simultaneous identification and correction of measurement and branch parameter errors (series and shunt admittances) in the power system SE problem. The proposed method uses Lagrange multipliers ...

Power system component failures can generally be classified into two categories: repairable random failures and aging failures. An essential step in power system reliability evaluation is the calculation of component unavailability. The paper presents a new model for calculating the unavailability due to aging failures using the normal distribution. It is based on the strictly mathematical deri...

Rice bran is a simple item that delivers fantastic health benefits in our daily diet. This study delivers the importance of utilising all parts of the whole grain, including the bran. The objective was to develop the recipes incorporated with rice bran and evaluate their organoleptic properties and estimate their glycemic index. Ten standard Indian subcontinent recipes namely, chapati, mixed ve...

We propose a decision-support aid for control room security economy decision-making that considers probabilistic characteristics of contingencies and load conditions of power systems. The approach is based on use of risk-based security assessment to enable treatment of security level as an objective within multi-criterion decision making (MCDM) techniques. The approach is illustrated using the ...

-After two decades of phasor network deployment, phasor measurements are now available at many major substations and power plants. The North American SynchroPhasor Initiative (NASPI), supported by the US Department of Energy and the North American Electric Reliability Corporation (NERC), provides a forum to facilitate cultivating the efforts in phasor technology in North America and globally. P...

We present empirical evidence that the distribution of effort required to solve CSPs randomly generated at the 50% satisfiable point, when using a backtracking algorithm, can be approximated by two standard families of continuous probability distribution functions. Solvable problems can be modelled by the Weibull distribution, and unsolvable problems by the lognormal distribution. These distrib...

Recent controversies in campaign finance have generated concerns that wealthy donors will dominate the political landscape, with Citizens United v. Federal Election Commission1 and McCutcheon v. Federal Election Commission2 standing as the high-water marks in the U.S. Supreme Court’s jurisprudential turn towards deregulation. This short Essay puts this case law in perspective by briefly explain...

The Oligochaeta forms an important part of the macroinvertebrates inhabiting sediments of lotic ecosystems. It has an important role in the cycling of matter and energy transfer in these environments. The aim of this study is to analyse limnological variables, their influence on the structure and diversity of benthic oligochaete taxocenosis in a stretch of the Upper São Francisco River and its ...

We review some work done by us calculating matrix elements for Kaons. Emphasis is put on the matrix elements which are relevant to predict nonleptonic Kaon CP violating observables. In particular, we recall our results for the B̂K parameter which governs the K0 − K0 mixing and update our results for εK including estimated all-higher-order CHPT corrections and the new results from recent analytic...

A list of the Tettigoniidae (Orthoptera) of the East Usambara Mountains is presented and 16 new species are described from East Africa. A total number of 29 Tettigoniidae species is recorded for the East Usambara Mountains. New species are described from the Shimba Hills in Kenya, coastal Tanzania from the Kazimzumbwi forest reserve, Mt Kilimanjaro, the East and West Usambara and Uluguru Mounta...
