We propose a new impedance control algorithm for delayed linear bilateral teleoperation systems. In the presented control strategy, with regard to a preferred impedance model for the master and slave robots, a special dynamic feature at the human and the master robot along with the slave robot and environment interface is proposed. In addition, external […]
Nowadays, power systems should be operated in the highest level of utilization and near their stability limits because of economic reasons. So stability assessment of the power system to determine the stability limits has been always considered. In SCADA/EMS systems a constant value called security margin and steady-state stability limit are used to determine transient […]
In this paper, a novel lossless snubber is introduced that provides ZVS conditions for both On and Off instant of converter switches. On one hand, the energy of the snubber is optimally transmitted to the output so that no significant losses are imposed on the converter. Since the converter diodes are switched off as ZCS, […]
Ultra-High precision Single-Point Diamond Turning (SPDT) is a widely used machining technology for generation components with optical grade surfaces. SPDT has been widely used in different industry sectors including aerospace, biomedical, military, defense, electronics, and entertainment. By using SPDT, manufacturing of optical surfaces with roughness down to one nanometer, even less than one nanometer, is […]
Hundreds of millions of homes worldwide already Have Fiber to The Home (FTTH) broadband connections since this technology holds many advantages over current technologies. The need for higher bandwidth by customers persists the network providers to upgrade their networks. The FTTH is the use of fiber optic cords to deliver communications signals from an operator’s […]
Recently, robotic manipulators are the key industry requirement. These have find the importance to enhance the productivity as well as accuracy. Furthermore, industries are also moving towards the use of Flexible Link Manipulator (FLM) owing to their unique characteristics i.e. light weight, high speed operations, and the larger workspace. The FLM system has flexibility of […]
The recent state of electrical system comprises the conventional generating units along with the sources of renewable energy. The suggested article recommends a method for the solution of single and multi-objective optimal power flow, incorporating wind energy with traditional coal-based generating stations. In this article, the two thermal power plants are replaced with the wind […]
DC microgrids have gained extensive attention in the recent years. In the islanded mode of operation power sharing between sources is required. The power sharing usually is provided by employing P-V droop characteristics while the voltage local property results in power sharing error. In this paper two decentralized approaches for resolving power sharing error are […]
One of the main focus areas in human body reconstruction is the regeneration of bone tissue in different body zones by using various reconstruction applications. In the last two decades, different efforts have been undertaken for developing new bone reconstruction methods, and supporting techniques for stimulating bone healing mechanisms. It has been shown that during […]
Cloud computing is introduced as a high-performance computing environment that manages a variety of virtualized resources. One of the major aspects of cloud computing is its dynamic scheduling of great number of task requests that are submitted by users. Cloud data centers in addition to implementing these tasks, should meet the conflicting multiple requirements of different […]
