 The Extended Littoral Battlespace (ELB) Advanced Concept Technology Demonstration (ACTD) uses wireless Local Area Network (LAN) technology to provide U.S. Marines in the field with multimedia connectivity to shore-based and afloat command and control centers. Computer network voice communication services are being evaluated and demonstrated as part of the ELB project. A gateway is needed for ...

In this article we will present a detailed study of recursive extended least squares method (RELS) to identify without bias of the models (system + disturbance). The idea is simultaneously to identify the model of the system and the model of the disturbance to obtain asymptotically a white error of prediction, which guarantees an unbiased estimate of the parameters system. Then we choose an app...

33 Volume images of the body are an indispensable clinical diagnostic tool. For visualizing and examining complex body organs such as the brain, doctors depend on the information 3D imaging modalities, such as x-ray computed tomography (CT) and magnetic resonance imaging (MRI), provide. Although these mature techniques have developed into reliable systems delivering high-quality images, some dr...

We report the discovery of a new pulsating DA white dwarf, or ZZ Ceti, from the list of the Palomar-Green survey, rediscovered in the ongoing Hamburg Quasar survey (HQS). PG1541+650 is one of the ZZ Ceti candidates listed in the analysis of 80 DA white dwarfs from the HQS. With an effective temperature of 12000 K, for a surface gravity logg=7.79, it lies in the ZZ Ceti instability strip. It is ...

The former Soviet encryption algorithm GOST 28147-89 has been standardized by the Russian standardization agency in 1989 and extensive security analysis has been done since. So far no weaknesses have been found and GOST is currently under discussion for ISO standardization. Contrary to the cryptographic properties, there has not been much interest in the implementation properties of GOST, thoug...
