model of material resources management, taking into account the importance hierarchy structuring information flows, in which conditions for gradual development intelligent agriculture are laid down. The proposals include: multi­module software internal and external integrated flows data on costs; a single digital platform opera tional with an expanded list suppliers, ability to search seeds, ag...

Following recent technological changes, the archival profession will reach moment of surpassing previously dominant mediaspheres, in which sounds and images were stored traditionally located archives. This is not to say that tradi?tional archives are needed anymore - on contrary. In this article, I try bring out possibilities upgrading traditional with help blockchain technology analyse complex...

This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...

Two directional UWB monopole antennas are proposed. It is shown that a design methodology for omnidirectional UWB rectangular planar monopole antennas can be applied for directional ones. The directional features are taken by introducing a slanting angle between the radiator and the ground plane. The slanting angle also plays a role in the low cutoff frequency, and it is considered in a propose...
