New Sorting Algorithm—RevWay Sort

Abstract: Sorting provides a method of rearrangement of elements in ascending or descending order. In this paper, we are introducing a new sorting algorithm called RevWay sort in which the two consecutive numbers are compared from left and then from right. This process is repeated \(((n/2)+1)\) times, where n is the total number of elements. We have compared running time of the proposed algorithm with other sorting algorithms. We run the algorithm starting from 10,000 to 50,000 elements. We found that the newly proposed RevWay sort yields lesser running time compared to bubble and selection sort. For 10,000 elements, RevWay sort takes 203.636 ms, whereas bubble sort takes 364.8243ms and selection sort consumes 337.5543 ms.

A Linear Voltage Controlled Quadrature Oscillator

Abstract: A linear voltage controlled quadrature oscillator (LVCQO) is presented; the design uses commercially available IC modules. The response had been experimentally verified with simulation and hardware test. The realization is based on an electronically tunable allpass filter (ETAF) coupled with a voltage controlled integrator (VCI). Quadrature oscillator tuning frequecy is measured in a range of $\mathbf{1}\leq \pmb{f}_{o} with satisfactory phase-noise response of −96 dBc/Hz. Effects of device parasitic are negligible.

Response of Equatorial Ionization in Indian Longitudes to HSSW Driven Geomagnetic Storm

Abstract: The paper reports the effects of a moderate High Speed Solar Wind (HSSW) driven Corotating Interaction Region (CIR) geomagnetic storm (minimum Dst ≤ -53 nT) on the ionosphere at Hyderabad (17.42°N, 78.55°E geographic, 8.93°N, 152.65°E geomagnetic) during August 4-8, 2019. Hyderabad is situated at geophysically sensitive Equatorial Ionization Anomaly (EIA) region between geomagnetic equator and northern crest of EIA. The results yield positive enhancement of Total Electron Content (TEC) during the main phase of the storm (August 5, 2019, increment of VTEC: 8.17 TECU). The effects of Disturbed Dynamo Electric Field (DDEF) were also observed during the recovery phase of the storm (August 6, 2019, decrement of VTEC: 7.56 TECU). Another TEC enhancement was observed during the recovery phase of the storm (August 7, 2019, increment of VTEC: 4.25 TECU). This could possibly be explained by the day-to-day variabilities of TEC at low latitudes and the impact of fading geomagnetic storm intensity coupled with strong solar wind.

Multi Objective Optimization of Expense and Revenue in a Cognitive Radio Network Using NSGA-II

Abstract: In this paper we consider an auction framework of cognitive radio network comprises of primary and secondary users (SU). The spectrum is divided into channels using frequency division multiple access (FDMA). Primary users have license to use the channels. When the channels are idle, primary users lease the vacant spectrum for monetary gain. Cognitive users or SUs bid for the channels. The purchaser who provides highest bid value is selected by primary user. Our objective is to maximize the revenue earned by primary users and to minimize the expense given by the secondary users. The problem is bi-objective and both the objectives are conflicting. Using Non dominated sorting genetic algorithm II; we solve both the objectives of primary and secondary users. The algorithm solves the problem well and find optimize values of both expense and revenue.

Investigation on Microwave MEMS Capacitive Shunt Switch by Using Coventor and CST Software

Abstract: In this paper, a detailed analysis of electrostatic and electromechanical aspects of RF capacitive shunt switch is presented. The effects of the membrane materials on different parameters of the switch are also studied for aluminium and gold membranes. The analysis is carried out for charges, electric fields, power handling capacity and hysteresis using MATLAB and further full wave analysis using COVENTOR.
