Multiple bands stacked patch antenna with circular polarization for satellite communications is proposed. The antenna is composed of two stacked patches with total dimensions of 45 × 45 mm and 40 × 40 mm for the lower and upper patches, respectively, separated by FR_4 as a dielectric material. One patch is fed through Microstrip line and other is fed through two VIAs. The proposed antenna is designed using the method of moments simulator of ADS and the simulations results show good performance in satellite communications bands around 1.41 GHz, and 1.55 GHz with gain of 3.42 dBi. Circular polarization is achieved from 1.42 GHz to 1.46 GHz.

The advent of alternating current (AC) is due to its ability to transmit power over long distances from transformers, does not mark the end of utilizing direct current (DC). The development of renewable energy sources is because of high usage of DC because the generated power is directed to the main grid for conversion into electric power and the source of energy cannot tolerate high voltage. Fault detection is a major problem that arises when an excess amount of current flows in the circuit leading to the necessity of having circuit breakers. Circuit breakers are made of light materials, which creates a problem for dealing with high voltage DC applications with the protection of circuit breakers have become popularized, and different papers have outlined various studies on the effectiveness of Solid State Circuit Breakers (SSCBs) protection for a direct current microgrid. This paper reviews the benefits and shortfalls of The Wide bandgap (WBG) SSCBs and its application with photovoltaic (PV) generators.

An error-function analytical expression describing compositional grading in a 850 nm AlGaAs/GaAs top-emitting oxide confined vertical cavity surface emitting laser has been derived. Results are presented showing that the optical properties of the considered device utilizing the proposed error-function compositional scheme are superior over other grading schemes found in the literature. The advantages of the presented scheme over other schemes lies in its ability and flexibility of controlling the degree of grading unlike the other schemes reported in the literature were the grading profile is dependent on the grading function used.

A Wireless Sensor Networks (WSNs) should be autonomous, self-sustainable and able to function for several years. However, due to the slow advancement in battery technology, battery power continues to be a limited resource in wireless sensor communication and thus electric energy storage remains to be an important issue. The aim of this work is to conduct a study on battery life estimation for wireless sensor communication. Three new batteries with different capacities: 55mAh, 550mAh and 5500mAh were considered in this study. The results show that an increase in the battery capacity increases the two-node wireless sensor system operation time. This result can be used to extrapolate the required battery capacity for extending the wireless sensor system life time.

Power prediction demand is vital in power system and delivery engineering fields. By efficiently predicting the power demand, we can forecast the total energy to be consumed in a certain city or district. Thus, exact resources required to produce the demand power can be allocated. In this paper, a Stochastic Gradient Boosting (aka Treeboost) model is used to predict the short term power demand for the Emirate of Sharjah in the United Arab Emirates (UAE). Results show that the proposed model gives promising results in comparison to the model used by Sharjah Electricity and Water Authority (SEWA).

This paper presents two approaches targeting the reduction of power dissipation, the delay time and silicon area of S7 and S9 blocks of MISTY1 encryption algorithm. The essential part of both approaches is to reduce the number of logic gates (XOR and AND gates) used in S7 and S9 blocks ciphers. The first approach reduces the number of logic gates by applying Boolean Algebra rules and simplifications, while the second approach removes the redundant logic gates which form the S7 and S9 blocks ciphers. The first approach reduced the dynamic power dissipation and the silicon area by 21.7%, 25.3%, respectively, while the throughput enhanced by 21.1%. The second approach reduced the dynamic power dissipation and the silicon area by 27%, 31.7%, respectively, while the throughput enhanced by 3.8%. As a result, the proposed approaches could be fit for next generation of handheld and portable devices.

Detecting malicious and selfish nodes is an important task in Vehicular Adhoc NETworks (VANETs). Various proposals adopted trust management as an alternative solution for it is less costly in terms of computation delay and mobility adaptation, compared to the cryptography-based solutions. However, the existing solutions assume that in general the attackers have always a dishonest behavior that persists over time. This assumption may be misleading, as the attackers can behave intelligently to avoid being detected. In this paper we propose a new solution for the detection of intelligent malicious behaviors based on the adaptive detection threshold. In addition to the detection of malicious nodes, our solution incite attackers to behave well since any malicious behavior will be immediately detected thanks to the adaptive detection threshold. We present simulations results which show the high efficiency of our proposal at ensuring high ratios for both detection and packet delivery.

This paper introduces a new methodology for designing a robust Radio Frequency (RF) amplifier. In this method; the dimensions (area) and power (DC current bias) are scalable to match the RF design specifications. Many parameters are used to optimize the design results. The frequency scaling up nonlinearity is minimized with the trimming technique. The proposed method is firstly based on designing with low frequency corner specifications to avoid the parasitic effects, and then, the scaling process is starting. The ACM MOST is useful in analog CMOS circuit design. In this model, the current inversion coefficient is used as the design key. A set of simplest expressions allows quick design analytically as well as an evaluation of the design in terms of power consumption or silicon real state. The methodology has been implemented using MATLAB program and proved to be very practical and promising. A set of RF CMOS cascode amplifiers designs demonstrate the reliability of the proposed methodology.

A miniaturized opened ended rectangular waveguide antenna radiating below the cutoff frequency of the waveguide is investigated. Miniaturization of the waveguide is achieved by loading the antenna with electromagnetic metamaterial (MTM) consisting of Square Shaped Ring Resonators (SSRR) or Circular shaped Ring Resonators (CSRR). These metamaterials provide the waveguide the ability to support the propagation of the backward wave below the cutoff frequency. The investigated open waveguide radiator was designed and simulated using High Frequency Structure Simulator HFSStm commercial software. Comparing the former work of miniaturized waveguides, we were able to obtain miniaturized antenna with 44.5 % reduction.
