In this paper, modeling and control strategies for a new observability-optimized piezoelectric microactuator are presented. The targeted applications concern mainly the design of microgripper for micromanipulation tasks. The device has been designed using a topological optimization method, which takes into account the optimal full integration of piezoelectric actuating and sensing elements with...

A novel liquid crystal (LC) wavefront corrector with smooth modal influence functions is proposed and realized. The device consists of a thin layer of planar aligned nematic LC sandwiched between a glass plate with a conductive electrode and a plate made of ceramic material with a very high dielectric constant. Control electrodes are positioned on the back side of the ceramic plate, opposite to...

dilution is limited primarily in its sensitivity. However, this is of concern only if very small numbers of organisms are suspected in a particular specimen, because the lower limits of detection for a 10-μL aliquot of undiluted material would be approximately 100 cfu/mL. There exists the possibility of crossing of paths as the plates are tilted. We experienced this problem only: (i) on media t...

Shading systems have the potential to reduce energy consumption of electric lighting and improve visual comfort. Various automated control systems of shading device and electric lighting have been widely used. However, existing lighting and shading systems typically operate independently, i.e., information is not shared, and thus system performance is not optimal. Therefore, integrated control ...

Strongly-coupled quantum dot molecules (QDMs) are widely deployed in the design of a variety of optoelectronic, photovoltaic, and quantum information devices. An efficient and optimized performance of these devices demands engineering of the electronic and optical properties of the underlying QDMs. The application of electric fields offers a knob to realise such control over the QDM characteris...

in this paper, plug-in fuel cell electric vehicle (pfcev) is considered with dual power sources including fuel cell (fc) and battery energy storage. in order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. in order to simulate the...

Electrical control of magnetic properties is crucial for device applications in the field of spintronics. Although the magnetic coercivity or anisotropy has been successfully controlled electrically in metals as well as in semiconductors, the electrical control of Curie temperature has been realized only in semiconductors at low temperature. Here, we demonstrate the room-temperature electrical ...

Today, the shortest time-to-market in the electric drives industries is being a pressing requirement, consequently development time of new algorithms and new control systems and debugging them must be minimized. This requirement can be satisfied only by using a well-defined System-level design methodology and by reducing the migration time between the algorithm development language and the hard...
