Electrified transportation will help to reduce green-house gas emissions and increasing petrol prices. demands that a wide variety of charging networks be set up, in user-friendly environment, encourage adoption. Wireless electric vehicle systems (WEVCS) can potential alternative technology charge the vehicles (EVs) without any plug-in problems. This paper outlines current available wireless power transfer for EVs. In addition, it also includes transformer structures with ferrite shapes,...

Developing next-generation cellular technology (5G) in the mm-wave bands will require low-cost phased-array transceivers [1]. Even with benefit of beamforming, due to space constraints mobile form-factor, increasing TX output power while maintaining acceptable PA PAE, LNA NF, and overall transceiver consumption is important maximizing link budget allowable path loss minimizing handset case temperature. Further, need be able support dual-polarization communication. An IF interface analog...

This article proposes a novel framework to improve the prediction accuracy of very short-term (5-min) wind power generation. The consists complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN), monarch butterfly optimization (MBO) and long memory (LSTM), called CEMOLS. CEEMDAN is employed extract complex hidden features time-series data into intrinsic functions that are predicted using LSTM models dropout regularization retain long-term relationships between input...

The design of an optimized electronically steerable passive array radiator (ESPAR) antenna is presented. A genetic algorithm using a finite element based cost function the antenna's structure and loading conditions for maximal main lobe gain in single azimuth direction. Simulated results 7.3 dBi at 2.4 GHz were attained along elemental axis. was fabricated tested with corresponding experimental better than 8 dBi. 0.7 dB error between simulated measured constant numerous structures therefore...

This paper set out to identify the significant variables which affect residential low voltage (LV) network demand and develop next day total energy use (NDTEU) peak (NDPD) forecast models for each phase. The were developed using both autoregressive integrated moving average with exogenous (ARIMAX) neural (NN) techniques. data used this research was collected from a LV transformer serving 128 customers. It observed that temperature accounted half of demand. inclusion double exponential...

This study proposes a new summation inequality, called the free‐matrix‐based which further extends certain existing inequalities in literature. Less conservative stability criteria are proposed for discrete‐time systems with time‐varying delays. Numerical examples provided to demonstrate improvement of approach.

Electric Vehicles (EVs) may significantly affect the stability of microgrids. To incorporate EVs with Vehicle-to-Grid (V2G) capability into frequency control, existing approaches have primarily focused on charge level batteries to derive participation individual EVs. However, examining only State Charge (SoC) does not provide an effective evaluation measure distinguish between varying owner expectations. Furthermore, proliferation renewable energies, will be required participate in voltage...

This paper introduces a new adaptive control strategy for power-sharing in hybrid AC/DC microgrid (HMG). The existing interlink converter (ILC) methods exhibit limitations under heavy load and contingency conditions. To overcome this limitation, bidirectional is proposed the ILC, which effectively coordinates battery energy storage systems (BESSs) both sub-grids while mitigating stress on ILC BESSs. utilises state of charge (SoC) instantaneous power BESSs to stabilise frequency DC voltage AC...

Base-station tracking in mobile communications benefits from a directional antenna and so requires direction finding technology. A novel technique for electronically directing the radiation pattern of an array employs with only one active element three parasitic elements operating near resonance. Three different methods are assessed; coarse angular location method, precise method assuming incident beam, multiple beams. An n elements, if used conjunction relatively simple controller, can be...

In this paper we extend operational transformation to support synchronous collaborative editing of documents written in dialects SGML (Standard General Markup Language) such as XML and HTML, based on SGML's abstract data model, the grove. We argue that concurrent updates a shared grove must be transformed before being applied each replica ensure consistency. express operations property changes positionally-addressed nodes, define set functions, show how apply an existing generic algorithm...
