Modifying natural droplet systems by charge injection

Simulation a Natural Gas Direct Injection Stratified Charge with Spark Ignition Engine

The purpose of present paper is simulation a direct injection stratified charge natural gas engine. The KIVA-3V code was used for gaseous fuel injection simulation. Compression and expansion stroke of engine cycle is simulated using KIVA-3V code. In cylinder fuel equivalence ratio distribution criterion is used for studying mesh independency. The results show that 550000 cells number is suff...

Modifying Charge Carrier Injection Using Self-Assembled Monolayers in Organic Field-Effect Transistors

Charge Injection Devices

|The name "charge injection" describes the operation of a generic class of electronic and optoelectronic multiterminal semiconductor devices, based on the real space transfer of hot carriers over a potential barrier into adjacent and separately contacted layers. Charge injection devices enable the implementation of compact optoelectronic gates endowed with a powerful logic functionality. Keywor...

Ethical Implications of Modifying Lethal Injection Protocols

Courts in the United States have historically judged execution methods against “evolving standards of decency,” and have prohibited punishments that involve “the unnecessary and wanton infliction of pain,” or more recently the “substantial risk of serious harm” [1]. Public repugnance and legal challenges to execution by cyanide gas and electrocution led to the development of lethal injection as...

A model based control of compressed natural gas injection systems

Low fuel consumption and low emissions are key issues in modern internal combustion engines design. For this reason, an effective on-line control of the injection process requires the mathematical equations describing the system dynamics. The inherent nonlinearities make the modeling of the fuel-injection system hard to accomplish. Moreover, it is necessary to trade off between accuracy in repr...
