We consider a point-to-point flat-fading MIMO channel with channel state information known both at transmitter and receiver. At the transmitter side, a lattice coding scheme is employed at each antenna to map information symbols to independent lattice codewords drawn from the same codebook. Each lattice codeword is then multiplied by a unitary precoding matrix P and sent through the channel. At...

The growth of open networks created the interest to commercialise it. The establishment of an electronic business mechanism must be accompanied by a digital – electronic payment system to transfer the value of transactions. Financial organizations are requested to offer a secure e-payment synthesis with equivalent level of security served in conventional paper-based payment transactions. PKI, w...

Cél: A Disaster Victim Identification (DVI) a tömegszerencsétlenségek, katasztrófák, terrorcselekmények áldozatainak azonosítását jelenti. válságkezelés szemszögéből egy apró, de annál fontosabb momentum, hiszen médiát, ezen keresztül lakosságot is az érdekli, hogy bekövetkezett incidenst, ahol többen életüket veszítették, mi vagy ki okozta, rendszer hogyan és milyen gyorsan reagált eseményre, ...

Certain fonts that you requested in your dvi file could not be found on the system. In order to print your document, other fonts that are installed were substituted for these missing fonts. Below is a list of the substitutions that were made. Certain fonts that you requested in your dvi file could not be found on the system.

The ISFG membership consists of scientists and medical professionals specialized in using genetic testing for kinship analysis and the individualization of biological material. This expertise makes the forensic geneticist a resource of advice to international and national organizations dealing with human identifications and causes many DNA laboratories to get involved in DVI tasks. The present ...

Between January 1985 and December 1991, six patients underwent arterial and bronchial sleeve resections of the left upper lobe. Preoperative and postoperative spirometry, preoperative split pulmonary radionuclide ventilation/perfusion (V/Q) scans and postoperative bronchoscopy were obtained in four patients. Postoperative serial digital vascular images (DVI) of the pulmonary artery were obtaine...
