Materials that can change one or more of its properties in response to an external stimulus are called smart materials. the shape of the material will change in response to different temperature or application of electrical charge or presence of MF
Polyfuses is a new standard for circuit protection .It is re-settable by itself. Many manufactures also call it as Polyswitch or Multifuse. Polyfuses are not fuses but Polymeric Positive temperature Coefficient Thermistors (PPTC)
Shape memory alloys (SMA's) are metals, which exhibit two very unique properties, pseudo-elasticity(An almost rubber-like flexibility demonstrated by shape memory alloys), and the shape memory effect (deformed and then returned to their original shape)
VSC Application for HVDC systems of high power rating (up to 200MW) which are currently in discussion for several projects. The underlying technology of VSC based HVDC systems, its Characteristics and the working principle are also presented.
A paper battery is a flexible, ultra- thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose based paper.
Infrared Thermography is nothing but the temperature profiling of a surface or point. As the name suggests, infrared thermography is based on Infrared(IR) technique. surface temperature can be detected and quantified by the help of IR scanning system.
voltage stability in power systems at which voltage stability in transmission lines and system buses are carefully analysed based on their V-Q and V-P relationships. Four indices are proposed; two for voltage stability analysis at system
One solution is to remove the driver from the control loop by fully automating vehicle driving functions.which include WLAN for connectivity, GPS navigation systems for navigation, Radar scanning to avoid collisions. eliminating human interference
CT scanning uses special x-ray equipment to obtain image data from different angles around a body and then shows a cross section of body tissues and organs. i.e., it can show several types of tissue-lung,bone,soft tissue and blood vessel with clarity.
Blood Collection Monitor is an advanced device which is aimed to collect the blood prior to collection with use of latest technology in place of earlier, insufficient, conventional methods i.e. without accurate weight by using random movement.
Distribution system is that part of the electric power system which connects the high voltage transmission network to the low voltage consumer service point.
Renewable energy sources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy sources include the sun, wind, water, geothermal energy and biomass.
The hybrid-cascaded multilevel converter proposed in this paper can actualize the charging and discharging of the battery cells while the terminal voltage or SOC balance control can be realized at the same time.
Solar tracking systems allows more energy to be produced because the solar array is able to remain aligned to the sun and therefore it will provide the maximum output power used in lightning the street lights at night.
Anti-inflammatory and anesthetic medications (dexamethasone and lidocaine) are the most common medications delivered using iontophoresis in physical therapy.
Energy management" is a term that has a number of meanings, but we're mainly concerned with the one that relates to saving energy in businesses, public- sector/government organizations, and homes.
Poka Yoke is a quality management concept developed by a Matsushita manufacturing engineer named Shigeo Shingo to prevent human errors from occurring in the production line.
Use of self-rechargeble paper thin film batteries, their performance and applications has been presented. The Glucose activated paper battery based on glucose oxidised enzyme using a simple and cheap plastic laminating technology has been demonstrated.
An electric powered bicycle carries batteries or fuel cells that deliver electric power to a motor that is coupled to either wheel.
The system is designed to detect the target (missile) moving in multiple directions. The destroying system moves automatically in the direction of missile and fires it upon fixing the target.
