A Study of Optimized Operation for CO2Emission and Aircraft Fuel Reduced Operation Procedures

Parametric Study of Operation and Performance of a PEM Fuel Cell Using Numerical Method

Output characteristics of fuel cells are affected by a large number of parameters such as geometry, dimensions, construction materials and conditions of supplying fluids. In this paper a mathematical model followed by a two-dimensional numerical approach has been presented to study the fuel cell parametrically. Effect of oxygen concentration at gas diffusion layer entrance, temperature and ...

Single Pilot Commercial Aircraft Operation

Optimized Charge Pumps for Subthreshold Operation

Over the last decade, the use of Field Programmable Gate Arrays (FPGAs) has grown from the design verification of digital systems to a wide variety of commercial and space applications for which low power consumption and re-programmability are paramount. To address the issue of low power, researchers have reported FPGAs incorporating a variety of design techniques to improve energy efficiency. ...

Optimized Self-Synchronizing Mode of Operation

Modes of operation adapt block ciphers to many applications. Among the encryption modes, only CFB (Cipher Feedback) has both of the following properties: Firstly it allows transmission units shorter than the block-cipher length to be encrypted and sent without delay and message expansion. Secondly, it can resynchronize after the loss of such transmission units. However, CFB is ine cient in such...
