In this paper, the main problems in signal management for safety data-transmissions are presented. Analysis of measurement results, combined with computer-estimated factors in estimation of ...disturbative effects of work environment for electric high-speed trains are included, in order to evaluate the best way to transit information between mobile and fixed equipment.

48 patients with the diagnosis of ACH, admitted in the interval 1972-1981 and subjuected to corticotherapy were investigated by hepatic puncture biopsy with Vim-Silverman needls. The dose of ...prednison was of 15-20 mg daily for 2-4 years, with a mean 20 months. Corticotherapy was efficient in 73% of the cases, stabilization of the clinical and hepatic functional pictures being obtained. In 17% of the cases the hepatic process persited unmodified and in 10% ACH evolved towards cirrhosis.
In this paper, we propose a variant of reconfigurable intelligent surfaces (RISs) called omni-digital-RISs (omni-DRISs), which allows both light reflection and refraction, with application to indoor ...visible light communication systems. The omni-DRIS contains elements which can be either reflectors or refractors, or both simultaneously. We describe and explain the concept of omni-DRIS, suggest and analyze an omni-DRIS coding structure, discuss metamaterials to be used in the omni-DRIS module, and provide a design example. Furthermore, we demonstrate that the achievable rate of an omni-DRIS system depends on the number of omni-DRIS elements, bits per phase shift, and actively absorbing elements. In addition, we show that the upper bound of the achievable rate is related to the number of omni-DRIS elements, and conclude by discussing future research directions.
Le PIB* (produit intérieur brut) mondial croît régulièrement à un rythme d’environ 3 % par an, tendance qui se maintient par-delà les variations conjoncturelles depuis cinquante ans. Cette croissance ...n’est pas uniforme, les inégalités entre les pays et à l’intérieur d’un même pays demeurent fortes. Et, à la hausse constante du PIB répond l’accroissement de la consommation, que reflète cet indicateur. La hausse de la consommation matérielle accompagne celle des revenus. Dans le contexte mondia...

In this article, we provide a brief overview of optical transmission systems and some of their performance specifications. We then present a simple, robust, and bandwidth-efficient OFDM ...synchronization method and carry out measurements to validate the presented synchronization method with the aid of an experimental setup.
