Abstract: Due to the daily rotation of the Earth, both its surface, including water, and the atmosphere constantly cross the lines of force of the geomagnetic field. For this reason, electromagnetic forces are constantly acting both on the earth's surface and in the earth's atmosphere. These forces distribute ground and atmospheric charges in both vertical and horizontal directions. The distributive action of the earth's electromagnetic forces is manifested in the characteristic polarization of the near-earth atmosphere and clouds, as well as in the appearance of celestial electric discharges and tornadoes. It is shown here that the same forces can cause negative electrization of the Sargasso Sea. It also shows that such negative electrization can be the cause of a number of anomalous phenomena occurring in the Sargasso Sea region, including a decrease in the buoyancy of ships sailing in the Sargasso Sea and a decrease in the lift of aircraft flying over its surface. At the same time, it is proposed here to use the positive electrization of ships sailing in the Sargasso Sea and aircraft flying over its surface to increase their buoyancy and lift, respectively. It also shows in detail the mechanism due to which the negative electrization of the Sargasso Sea air reduces the metabolic rate of the human body, in general, and, in particular, of the nervous tissue, including the brain. Thus, here is the most detailed analysis of the physical and physiological reasons that determine the anomaly of the Sargasso Sea.

Abstract: Hyperthermia has been introduced as a therapeutic method and adjuvant therapy in the treatment of some diseases such as breast and pancreatic cancers. On the other hand, other applications of hyperthermia have been considered. In this article, ways to treat knee pain caused by osteoarthritis, patellar chondromasia, rheumatism, knee infection, etc., have been studied using antenna hyperthermia. For antenna hyperthermia, is using a rectangular microstrip antenna, which is the simplest type of antenna. The antenna considered in this article has conformal conditions and is designed in the shape of a knee structure, to create a suitable knee covering. The antenna considered in this article has conformal conditions and is designed in the shape of a knee structure, to create a suitable knee covering. In addition to the geometric structure of the antenna, which fits the structure of the knee, the resonance frequency of the antenna is in the range of ISM standard frequencies and attempts have been made to place it at 2.4 GHz. On the other hand, to show the thermal pattern created by the antenna, the specific absorption rate of the tissue is investigated and its diagram is simulated by the antenna radiation field.

Abstract: Radio spectrum is becoming scarce due to increasing demand for high data rate, mobile communication and ever-expanding population with diverse need to always stay interconnected. The cellular network providers and researchers in the academia are continually finding innovative ways to efficiently manage the existing telecommunication infrastructure and plan effective for future expansions and technology. Device to Device (D2D) communication, Full-Duplex (FD) radio, Heterogeneous network are a few of such innovative technologies developed to face the challenges. Device to device communication is one promising technology that is studied for deployment in future network technologies, however it is not without its challenges. Various researches have been carried out and are still being carried out to better understand and improve device to device capabilities. The use of full-duplex radios is an area of study with capability for improving device to device communication due to recent development in full-duplex radio although its major drawback is limited self-interference cancellation abilities to be deployed in large transmit power system. This research presents the practicality of deploying existing FD radios in device to device communication and simulate the amount of self-interference cancellation required using MATLAB for effective use with device to device. Two interference management schemes were implemented to improve the performance of FD-D2D communication, first power control scheme was developed to mitigate interference between D2D and base station in uplink resource sharing, Interference Limited Area (ILA) method was adapted to deal with interference between D2D and cellular user Uplink and Downlink transmission. The performance between 75dB to 110dB Self-Interference (SI) cancellation was carried out. The result was compared to conventional cellular and Half-Duplex D2D communication to estimate the improvement offered on spectral efficiency. The work has improved on achieving almost 100% spectral efficiency thereby improving the Quality of Service (QoS) for cellular network
