Secure and economic operation of the power system is one prime concerns for engineers 21st century. Unit Commitment (UC) represents an enhancement problem controlling operating schedule units in each hour interval with different loads at various technical environmental constraints. UC complex optimization tasks performed by plant regular planning system. Researchers have used a number metaheuri...

A linear and convex model has been recently presented for the operation of battery energy storage units that does not explicitly prevent their simultaneous charge discharge in problem formulation. This letter claims such a literature contribution is capable ensuring physical realizability dispatch only when nondiscrete decisions are considered optimization problem. claim demonstrated through so...

The U.S. Army Reserve struggles with retention and faces difficulties with soldier turnover. The intent of the study was to assess key psychological variables such as optimism and hope to establish how those traits might impact soldiers' level of organizational commitment and turnover intention in the Army.
