Line-switching operations introduce several concerns to microgrid operators since they trigger reliability and power quality issues in addition increasing the wear tear cost of switching devices. This paper proposes a novel methodology for achieving seamless line-switching low-inertia islanded microgrids. The proposed aims at mitigating detrimental impacts by minimizing flow switched lines mome...

Background and Objectives: Hospitals usually generate large amounts of hazardous waste. If not managed properly, hospital waste can pose threats to public safety and damage the environment. Waste minimization is a waste management approach that focuses on reducing the amount and toxicity of hazardous wastes. This study pursues a two-fold purpose: 1) to gain insight into hospital waste minimizat...

Two phenomena can produce chattering: switching of input control signal and the large amplitude of this switching (switching gain). To remove the switching of input control signal, dynamic sliding mode control (DSMC) is used. In DSMC switching is removed due to the integrator which is placed before the plant. However, in DSMC the augmented system (system plus the integrator) is one dimension bi...

The total number of switching pulses permitted in one-quarter the fundamental-cycle an inverter is restricted due to restrictions losses high-power devices. elimination major low-order dominating harmonics using SHEPWM (Selective Harmonic Elimination) suggested this research paper. positive or negative voltage transition at instant where fundamental has greatest slope distinguishes various type...

AIM To explore the benefits and harms of corticosteroid (CS) minimization following renal transplantation. METHODS CS minimization attempts to improve cardiovascular risk factors (hypertension, diabetes, dyslipidemia), to enhance growth in children, to ameliorate bone disease and to lead to better compliance with immunosuppressive agents. Nevertheless, any benefit must be carefully weighed ag...

In this paper, typical analog combinatorial optimization approaches, such as Hopfield net, Hopfield-Lagrange net, Maximum entropy approach, Lagrange-Barrier approach, are systematically examined from the perspective of learning distribution. The minimization of a combinatorial cost is turned into a procedure of learning a simple distribution to approximate the Gibbs distribution induced from th...

This paper describes a new method for extracting facial components from a color image using cooperative active nets with global constraints. We utilize an active net model which is a region extraction method based on energy minimization principle. Each net deforms with its own energy being minimized and the position of the nets are controlled by minimizing an additional energy de ned by global ...

Flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. Recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...
