Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...

Computer architectures can use custom logic in addition to general purpose processors to improve performance for a variety of applications. The use of custom logic allows greater parallelism for some algorithms. While conventional CPUs typically operate on words, fine-grained custom logic can improve efficiency for many bit level operations. The commodification of field programmable devices, pa...

Real-time 3D visualization of objects or information becomes increasingly important in everyday life e.g. in cellular phones or mobile systems. Care should be taken in the design and implementation of 3D rendering in such embedded devices like handhelds devices in order to meet the performance requirement, while maintaining power consumption low. In this work, the design and implementation of a...

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...

One of the most growing areas in the embedded community is multimedia devices. Multimedia devices incorporate a number of complicated functions for their operation, like motion estimation. A multitude of different implementations have been proposed to reduce motion estimation complexity, such as spiral search. We have studied the implementations of spiral search and identified areas of improvem...

Maintaining bonds of cohesion between members of small groups in densely populated venues (e.g., a family in an amusement park, or some friends in a stadium) is increasingly gaining interest, both as a safety measure against malicious activity and as a convenient tool to prevent group splitting. Note that the use of mobile phones is often ruled out in such scenarios, due to extreme network load...

In recent years, the penetration of renewable energy sources (RES) in microgrids and distribution system feeders has increased manifold. Moreover, advancement power electronics-based devices significantly number sensitive loads. Variations voltage under intermittent RES create functional problems with loads, necessitating regulators (VR) installation. this paper, two custom devices: dynamic res...

More than one hundred countries are using wind energy due to their easy implementation, cheap energy, and high energy efficiency. Implementation of FACTS devices in Wind Energy Conversion Systems (WECS) has been dramatically improved due to cooperative and accurate performance of FACTS devices. However, dealing with wind turbine faults promptly is crucial. Short-term and long-term faults may ha...
