The experimental results carried out on a fabricated antenna agree well with the theoretical results. Strategies for emergency load shedding must be planned in advance so that the operating constraints are satisfied in the present condition and in the next interval predicted load condition. The paper, "Preventive Load Shedding for Avoiding Line Overload Under Emergency Conditions Using Sine-Cosine Technique and Accounting for Distributed Generations" by Pradeep Purey, Rajesh Arya and S C Choube, presents an algorithm for optimal load shedding in advance such that operating constraints are satisfied in the present condition and in the next interval predicted load condition. The algorithm has been implemented on a 14-bus standard test system with distributed generation.

The paper, "Jaya Algorithm-Based Optimized Automatic Generation Control Scheme for Interconnected Solar-Thermal Power System" by S Bhongade and Vishnu Prasad Parmar, studies Automatic Generation Control (AGC) of a two-area thermal system incorporating Solar Thermal Power Plant (STPP) in one of the areas. A new optimization technique, i.e., Jaya algorithm, is used for the optimization of secondary controller gains. It is observed that Jaya optimized PID controller's performance is better compared to the conventional proportional integral and derivative control.

The paper, "Cost-Effective IoT-Based Home Automation Fault Detection and Monitoring System" by Gajendra Kumar, Rakesh Kumar Sahu, Vikas Kumar Lodhi and Yugal Kishor Sahu, describes an Internet of Things (IoT) project based on NodeMCU board for home automation. A new feature for fault detection and monitoring is introduced using current sensors. Hearing-aid designs are continuously being improved to minimize background sound localization. The paper, "Signal Processing Techniques Used in Digital Hearing-Aid Devices: A Review", by Manik S Sonawane and S R Chougule, reviews various designs and reconfigurable digital filter banks to achieve the best fitting to audiogram.

Broadband Rectenna with Full-Wave Rectification
Sharanbasappa B Belamgi and Sudhabindu Ray

The paper studies a broadband full-wave rectifying-antenna (rectenna) which utilizes both half cycles for RF wireless energy transfer. The proposed full-wave rectenna configuration is designed using a broadband dual edge-feed microstrip antenna and a bridge rectifier. This antenna is inherently broadband in nature and can provide differential voltages at its two edges with respect to its center at TM01 mode. Various output properties for the proposed rectenna configuration are also studied. An optimized rectenna is finally fabricated for experimental verification and measured results agree with the theoretical results.

Preventive Load Shedding for Avoiding Line Overload Under Emergency Conditions Using Sine-Cosine Technique and Accounting for Distributed Generations
Pradeep Purey, Rajesh Arya and S C Choube

At times, emergency load shedding is required based on predicted load in next interval. Under such situations, the load shedding strategy must be planned in anticipation and may be implemented after the load increase or in previous interval itself. In view of this, the paper presents a methodology for optimal load shedding in advance such that operating constraints are satisfied in the present condition and in the next interval predicted load condition. The effect of distribution generation has been considered. Sine-cosine optimization technique has been employed to get minimum load shedding at minimum buses. The algorithm has been implemented on a 14-bus standard test system.

Jaya Algorithm-Based Optimized Automatic Generation Control Scheme for Interconnected Solar-Thermal Power System
S Bhongade and Vishnu Prasad Parmar

The target of the programmed age control (Automatic Generation Control, AGC) is to direct the yield intensity of the electrical generator within an endorsed territory because of the deviation in recurrence and tie-line control. The paper presents AGC of two regions? traditional framework with sun-oriented warm power plant in one of the territories. A novel optimization, i.e., Jaya algorithm, is used for AGC control of power framework with or without solar energy. Jaya algorithm is fast convergent for controller gain of the Proportional-Integral-Derivative (PID) controller. The performances of Integral (I), Proportional-Integral (PI) and PID controller with Solar Thermal Power Plant (STPP) are evaluated. The results reveal that the PID controller provides better results than I and PI. The Jaya optimized PID with STPP gives better dynamic performance such as settling time, overshoots and undershoots as compared to the thermal power system.

Cost-Effective IoT-Based Home Automation Fault Detection and Monitoring System
Gajendra Kumar, Rakesh Kumar Sahu, Vikas Kumar Lodhi and Yugal Kishor Sahu

At present, automation is common in commercial and domestic applications. In the current state of affairs, automation is not only about controlling things when the users are physically present at that exact place, it specifically means that they can control it from any place within the world. The paper presents web-based home automation with fault detection and monitoring approach. A nodeMCU board is employed as a brain of this method and to establish a connection with the internet. Together with that, a current sensor is employed for fault exploration and monitoring the activity of the appliance. Current is a governing parameter in the electricity world. Each appliance works properly for a selected worth of current. Further, a relay board is employed to regulate the appliances. Thus, in this paper, an infrequent approach is introduced to show the current status of the appliances, that it is on/off. And it additionally provides manual operative approach together with IoT-based automation by coordination of various relays.

Signal Processing Techniques Used in Digital Hearing-Aid Devices: A Review
Manik S Sonawane and S R Chougule

Hearing impairment is a commonly observed human health problem across the world. In "hearing loss", hearing sensitivity is reduced. To treat hearing loss problem, hearing assistive devices are used. Hearing aids restore hearing ability for those having hearing problems. But with today's most advanced technologies in hearing aids, patients still have some difficulty in understanding speech in crowded areas. Hearing aid has hearing loss match up and adjustment of the hearing aid characteristics according to an individual patient. Digital hearing-aid device amplifies sound selectively by use of digital filters and the processed signal is transferred to the ear. Hearing-aid designers are continuously trying to minimize background sounds and noise with these additional directional microphones, adaptable noise reduction filters and uses of binaural hearing aid technologies to improve localization. Lots of studies have been already done to design digital filters for selective amplification. Most of the available hearing-aid designs have digital filter bank and fixed sub-band structure. Previous research aims at creating band decomposition, and the research is focused on using less complex algorithms for accomplishment of the decomposition of signals. The paper reviews available designs and reconfigurable digital filter banks to achieve the best fitting to audiogram.
