Few years ago Power Systems consisted mainly of large generation plants supplying distant loads through the utility grids. The last years, though, a number of factors lead this structure to change gradually. Small generators of some MW have been already dispersed (DGs) throughout the transmission grid. The distribution of smaller generation units throughout the distribution system as near as po...

This paper proposes an intelligent hybrid control system (IHCS) for identification and control of micro-permanent-magnet synchronous motor (micro-PMSM) servo drive to achieve high precision tracking performance. Based on the principle of computed torque control (CTC), a position tracking controller is designed and analyzed. Moreover, to relax the requirement of the lumped uncertainty, an IHCS i...

to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...

This paper presents a data gathering for Advanced Process Control (APC) in FA (Factory Automation). It is important that the gathered data in FA to control all the processing, to be a predictive maintenance of equipments and manage products. We gathered the entire data of all in FA through Equipment Engineering System (EES) and analyzed that to control a processing, predict the next processing ...

BACKGROUND AND OBJECTIVE In the present study, micro-channel arrays were fabricated on the surface of plastic-based disposable chips. The cell adhesion process and the detection of plaque-forming macrophages were observed. Further, we evaluated cell adhesion in a fluid system in vitro. MATERIAL AND METHODS Features of the micro-channel (1.4 mm wide and 10 mm long) included twenty micro-pillar...

Soldier-portable UAVs enhance combat situational awareness by providing an over-thehorizon surveillance platform. This advantage can be multiplied by using multiple microhelicopters (< 20 g, < 20 cm) that operate cooperatively to obtain synoptic vantage points. Cooperative control of multiple helicopters using theoretically justified control laws requires a mathematical model of micro-helicopte...
