MAGNIFYING PHOTOGRAPHY OF MAMMA WITH LOW VOLTAGE AND SAME PHASE

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Design and simulation of a RF MEMS shunt capacitive switch with low actuation voltage, low loss and high isolation

According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...

Voltage Unbalance in Low Voltage Networks with Single-phase and Three-phase Micro-generation and Loads Jes

The incorporation of clean energy sources in the power system is a topic of discussion almost everywhere. After the “wind (farms) of change”, small, dispersed, urban photovoltaic (PV) generators are being installed in the roofs of the buildings, connected to the local Low Voltage (LV) grid. A boost in this type of renewable micro generation is expected in the near future. Due to the domestic lo...

Low Phase Noise Voltage - Controlled Oscillator

Low voltage blue-phase liquid crystal displays

A protrusion electrode structure is proposed to dramatically lower the operation voltage of the emerging blue-phase liquid crystal displays BP-LCDs . Simulation results indicate that the generated horizontal electric field is not only strong but also penetrates deeply into the bulk LC layer. As a result, a low voltage 10 Vrms and reasonably high transmittance 70% BP-LCD can be achieved. This ap...
