This paper presents a new scheme for power system stability enhancement using emergency control. The proposed scheme is based on a grid rulc-based fuzzy classification approach for power system security evaluation. Generator tripping is adoptcd as the emergency control technique followed by the necessary load shedding, if needed. The proposed strategy was tested through numerical simulation for...

appropriate scheduling and sequencing of tasks on machines is one of the basic and significant problems that a shop or a factory manager encounters; this is why in recent decades extensive studies have been done on scheduling issues. one type of scheduling problems is just-in-time (jit) scheduling and in this area, motivated by jit manufacturing, this study investigates a mathematical model for...

Fault detection and diagnosis for jet engines is complicated by the presence of engine-to-engine manufacturing differences and engine deterioration during normal operation, the complexity of an accurate engine model, and our inability to directly measure certain engine variables. Here, we work with a sophisticated component level model (CLM) simulation of a turbine engine (the General Electric ...

Aging is associated with decline in a multitude of cognitive processes and brain functions. However, a growing body of literature suggests that agerelated decline in cognition can sometimes be reduced through experience, cognitive training, and other interventions such as fitness training. Research on cognitive training and expertise has suggested that age-related cognitive sparing is often qui...

BACKGROUND Aging may cause various functional abilities gradually deteriorate. With changes in social forms, the trend of functional fitness decline will change accordingly. Therefore, this study endeavored to identify the trends in functional fitness decline by comparing the differences in the functional fitness of females in various age groups. METHODS Thirty six healthy females were divide...

Global warming and climate change become a sensitive issue worldwide, many countries try to control the CO 2 emissions by investigating in projects. This study proposes sustainable inventory model reduce carbon emission. It is generally assumed that demand increasing at starting of an level decreasing ending for particular newly launched product. In this situation, usually represented Normal di...

Due to fluctuation of the market and several other reasons, most parameters related production inventory system, like, deterioration rate, demand rate different costs are not always constants. These involve some sorts impreciseness which may be represented by stochastic, fuzzy, fuzzy-stochastic, interval, intuitionistic neutrosophic etc. approaches. In this work, a green model is formulated for...
