Security assessment (SA) refers to the analysis required to determine whether or not a power system can meet specified reliability and security criteria in both transient and steady-state time frames for all credible contingencies. This paper proposed a review in application of artificial neural network (ANN) in power system security assessment. Systems security identification, neural network c...

the paper determined optimum farm plan for food security among smallholder farmers in imo state, nigeria. data were collected with structured and validated questionnaire from 180 smallholder crops farmers in imo state. data were analyzed using descriptive statistics (mean, frequency distribution and percentages), budgetary analysis and linear programming model. results show that the mean age of...

foam injection is widely applied in amounts of fields to drilling, production, and formation protection. sometimes, the application result is disappointing, which is caused by the failure of bubble generation in foam flooding. therefore, it is necessary to seek ways for improving the performance of foam injection. an increased disturbance to the stratum, like the vibration caused by a seismic o...

-  Power system state estimation is a central component in energy management systems of power system. The goal of state estimation is to determine the system status and power flow of transmission lines. This paper presents an advanced state estimation algorithm based on weighted least square (WLS) criteria by introducing virtual meters. For each bus of network, except slack bus, a virtual meter...

With the advent and development of the Internet of Things, new needs arose and more attention was paid to these needs. These needs include: low power consumption, low area consumption, low supply voltage, higher security and so on. Many solutions have been proposed to improve each one of these needs. In this paper, we try to reduce the power consumption and enhance the security by using SPGAL, ...
