Most Canadian remote communities are supplied electricity partly or wholly generated by diesel generators, which results in high electricity costs mostly due to the cost of transporting fuel to the remote locations. A large portion of the financial budget from the government or local community is allocated to cover the cost of diesel electricity generation. Renewable energy integration can substantially

The demagnetization of switched reluctance motor (SRM) is usually a nonnegligible problem as the speed increases due to large back electromotive force (EMF). A slow demagnetization causes long tail current and negative torque, which reduces the efficiency and the output capability of SRM. In the conventional SRM design method, the inductance slope is normally designed to be high. However, it causes

This article presents a dynamic voltage restorer (DVR) topology based on the adaptive noise canceling (ANC) technique, which can be used for both voltage compensation and harmonic mitigation. Furthermore, this article aims to investigate the DVR performance when installed in a microgrid (MG) during both normal operation of the utility and during utility disturbances. One of the main objectives of this

This account details the design and construction of a sophisticated tracking wheel for the accelerated aging of polymer insulators by subjecting them to surface contamination and high voltage. Automated control of wet-dry cycles is achieved by means of a computer-controlled lift mechanism that operates in tandem with the rotation. The applied voltage is continuously variable and can accommodate insulators

Based on the optimized coprime array (OpCA), we propose a real-valued Toeplitz matrix method. This article analyzes the feasibility of converting the manifold matrix of a virtual domain constructed from a physical array into a real-valued matrix, and the unitary estimation of signal parameters via rotational invariance technique is introduced to transform the equivalent received signal rearranged Toeplitz

The use of cloud Infrastructure as a Service (IaaS) for enterprise applications is at an all-time high and is charted to continue growing to approximately 73% by 2022. IaaS suffers from several security concerns, such as hypervisor hijacking, virtual machine (VM) hopping, and account hijacking. With such a large percentage of enterprise traffic on the cloud, a strong security framework is demanded

The rapid evolution of field-programmable gate array (FPGA) devices has strongly influenced both the design methodology and development tools. This article describes an original implementation based on a hardware structure used for static and dynamic task scheduling. The proposed custom processor has hardware-implemented RTOS (HW-RTOS) features and is verified using an FPGA circuit. The solution replaces

Traditionally, the data rate of a digital signal processing system is bound by the processing speed. In this article, a formal approach for overcoming this limitation and allowing high-data-rate applications to run on relatively slow processors is presented. This approach allows the time sampling period to be much shorter than the time required to process an input sample; in effect, an ultrahigh-speed

In order to improve transient response and robust tracking performance, an adaptive nonsingular terminal sliding mode control (ANTSMC) strategy is developed for bidirectional dc–dc converter (BDC) of hybrid energy storage systems (HESSs). By using the adaptive rules, the estimated values of load variations, external input voltage, input current, and output voltage can be obtained. Then, the voltage

This article introduces a concept to extend the base speed of a switched reluctance motor (SRM) from the perspective of the motor’s design. Conventionally, designs prioritize a high saliency of SRM in order to produce more torque with the same current. However, the speed range is limited in the conventional design. The back EMF is the key factor that restricts the speed of the SRM from further increasing

This article presents two new approaches of fetal electrocardiogram (ECG) signal (FECG) separation using the input-mode adaptive filter (IMAF) and the output-mode adaptive filter (OMAF). Both approaches use the recursive least-squares (RLS) and the least-mean-squares (LMS) algorithms and a single-reference-generation block. In the IMAF, the filter’s primary input is connected directly to the abdominal

Many noncoherent distributed strategies for cooperative sensor networks that do not require channel knowledge at any antenna to overcome the overhead involved in channel estimation are lately suggested; however, these strategies suffer from low system performance in terms of bit error rate (BER) and a comparably high decoding complexity. Differential beamforming strategies have recently been proposed

Ternary content addressable memories (TCAMs) have a lookup complexity of O(1). They require just one memory access to find an entry. For this reason, they are widely used in core routers of the Internet to achieve high packet forwarding capacities in terms of several 100 Gb/s. However, in a TCAM, the routing table needs to be stored in a sorted order according to the prefix length of the entries. Therefore

A microstrip circular patch antenna with frequency and polarization reconfigurability using liquid metal is presented. The antenna has a C-shaped slot cut at the center of the patch and reconfigurability is achieved using two putty containers and liquid metal to switch between four different states. Linear polarization (LP) is observed at 5.83 GHz when there is no liquid metal inside the containers

Using dynamic partial reconfiguration (DPR) feature in field-programmable gate array (FPGA) systems seems inevitable by considering the tremendous benefits, such as reduced cost and power. Nowadays, manual floorplanning is one of the difficulties in implementing DPR systems, which relies on the designer’s views and his command over designing the concepts for arranging the modules on the physical layout

We present a parametric framework (UFleSe) with a user-friendly interface having a search engine that enables regular users (without the need of neither technical nor theoretical knowledge) to define their fuzzy concepts, rules, similarity relations, synonyms, antonyms, and personalizing their definitions for different users, and to link them with the crisp database fields for performing flexible,

This article is concerned with the asymmetrical control strategies of a four-channel dc/dc buck converter in the continuous current conduction mode (CCM). The converter has two input and four output channels. Energy equations of the converter are studied, and asymmetry of input voltages, output voltages, and loads are examined in the CCM. The proposed control strategy allows us to directly control

We present a novel scheme to formulate the throughput and the average number of successfully transmitted packets in a multinode Bluetooth low-energy (BLE) platform during each connection event. In this scheme, the wireless link is considered to be error prone which leads to the existence of uncorrelated bit error. Our proposed scheme considers factors that cause a connection event to close. The effect

This article develops a novel average torque control (ATC) scheme for switched reluctance (SR) motor on the basis of a brand-new microstep flux–current locus controller. The proposed ATC is based on the calculation of the average torque from the converted mechanical energy that can be illustrated as an enclosed area in a flux–current plane. It has the superior advantage that it is able to control the

Due to the growing complexity of today's digital circuits, the speed of fault simulation has become increasingly important. Although critical path tracing (CPT) is faster than conventional methods, it is not fast enough for fault simulation of complex circuits with a large number of faults and tests. Exact stem analysis is the most important obstacle in accelerating the CPT method. The simplification

The proposed structures have the advantage of computing both modular multiplication and squaring simultaneously for fast execution of modular exponentiation. They share the same hardware components for both operations and this gives them the advantage of saving
