Device modeling of long-channel nanotube electro-optical emitter

Modeling of a Carbon Nanotube Sensing Device

A sensing device is modeled and discussed in this paper. The modeling is done by using carbon nanotubes. This carbon nanotube based sensing device makes it possible produce huge amount of nano chips as a disposable cartridge for diagnostic purposes. Modeling of nano-electrode, characterization and electrochemical detection of DNA hybridization is discussed here. The results shows that the impor...

Measurement and Simulation of a High-Speed Electro/Optical Channel

Mathematical Modeling of Optical-Fiber Refractometric Device

We present a ray-tracing application in the modeling of an optical detection element employed as a sensor of refractive index of surrounding fluids or gases. The detection element is a solid glass microstructure having a surface of the second order. We exploit the sensitivity of internal reflection of light on the element’s surface to the refractive index of the surrounding medium, operation ne...

A New Conveyable Device for Electro-drainage of Thorax

Chest tube is a flexible plastic tube used to discharge secretion in the cavity between the lungs and chest named pleural cavity. Normally, there is a small amount of fluid in the cavity between the lungs and chest; This fluid helps the movement of lungs during breathing without abrasion. Entrance of bit of air, blood or pus because injury in the pleural cavity can prevent the lungs from fully ...

Modeling of RF Waves in Free Space Optical Communication System Under Gamma-Gamma Turbulent Channel Effect

In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...
