The emerging need for more power has led to the development of series-parallel connected battery cells. Having a more complex system also brought with it new challenges. One of these is the problem of cell imbalance. Balancing algorithms are based on extracting or adding charge in order to have balanced cells. Their goal is to protect the battery from damage and to help prolong the battery’s li...

Cloud Environment allows users to access on-demand IT resources over the cyberspace based on pay per use pattern. Optimizing the resource utilizationand reducing the amount of active server machine usage in clouds become a challenging task. The major intend of this work is to builda model which supports balancing the workload in cloud datacenters and minimizing the amount of active servers to s...

optimal balancing is a new approach based on optimal control a which modes, controls and the amount of equilibrium scale are calculated simultaneously. this approach has a significant effect on increasing performance of industrial robots which causes maximum decreasing of energy consumption. despite many applications of robotics such as welding and gluing, the path is predefined , but other unk...

Limited attention may constrain animal behavior in situations in which the rate of relevant information exceeds the threshold processing capacity of the brain. In the present study, we examine why attention is limited by quantifying how attention affects the ubiquitous problem of balancing foraging and antipredator activity. We analyze how a given attentional capacity affects feeding requiremen...

This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nat...

Stakeholder theory is widely recognized as a management theory, yet very little research has considered its implications for individual managerial decisionmaking. In the two studies reported here, we used stakeholder theory to examine managerial decisions about balancing stakeholder interests. Results of Study 1 suggest that indivisible resources and unequal levels of stakeholder saliency const...

The paper analyzes different concepts for active charge balancing for a multi-cell battery energy storage system used as a backbone for a DC micro grid. The storage system is based on a cascaded multi-level converter topology where each (lead-acid) battery is equipped with dedicated low-voltage buck type DC/DC converter stage placed directly at the battery terminals. To minimize the output ripp...

This paper suggests a new control method to modify the virtual impedance performance in unbalanced conditions. The proposed method compensates the voltage drop that occurred due to the virtual impedance and adjusts the voltage of the point of common coupling at a desirable level. To compensate the voltage drop, the reference voltage in the droop control varies according to the proposed algorith...

An active Web cluster system is an active network that has a collection of locally distributed servers that are interconnected by active switches, providing a Web application service. In this paper, we introduce the ALBM (Adaptive Load Balancing and Management) active cluster system that provides proactive management. The architecture of the ALBM active cluster and its underlying components are...
