In this paper, an area-efficient 4-stage dual-fed distributed power amplifier (DPA) implemented in a 0.35 μm Complementary Metal Oxide Semiconductor (CMOS) process is presented. To effectively reduce the area of the circuit, techniques such as using mu... see more

One of the best-known cyber attacks, distributed denial of service (DDoS), is evolving. It has become much more malefic and effective with the use of amplification power of reflected messages. This attack is known as the distributed reflected denial of se... see more

Aiming at the online monitoring of real-time operating of lithium-ion energy storage batteries for distributed power station, this paper studies the online monitoring system of lithium-ion energy storage batteries based on B/S network structure. The syste... see more

In order to guarantee the quality of service (QoS) for primary users (PUs) and secondary users (SUs) in fading channel, a distributed power control algorithm is proposed based on convex optimization theory in underlay OFDM cognitive ra... see more

A robust distributed optimal power control (RDPC) scheme under worst case condition is proposed to make primary users (PUs) receive minimum interference generated from all secondary users (SUs) in underlay cognitive radio networks (CRNs). The strategy con... see more

The RF power amplifier demonstrators containing each one GaN-on-SiC, HEMT, CHZ015A-QEG, from UMS in SMD quad-flat no-leads package (QFN) were subjected to thermal cycles (TC) and power cycles (PC) and evaluated electrically, thermally and structurally. Tw... see more

Purpose. The research main purpose is the perfection of magnetolevitating technology on electrodynamic suspension and providing its functioning on the base of ecologically rational energy systems. It means creation of the MAGLEV transport-power system whi... see more

This work aims to develop a model capable of evaluating the behavior of distributed energy resources in 13-nodes IEEE systems as a result of the change in the disconnector’s opening protocol that creates a power generation island. The first scenario simul... see more

This paper provides a detailed description and all the procedures involved in designing a power amplifier using microstrip technology and the design software Microwave OfficeTM. Specifically, the design is oriented to build an amplifier with central frequ... see more
