This article presents a small antenna for UWB applications on FR-4 Epoxy substrate material with a percentage bandwidth of 147% covering the frequencies from 3.08 GHz to 18.85 GHz. The antenna has a CPW-fed monopole-like structure that facilitates its easy fabrication and interface with other system components. The geometry offers a high frequency bandwidth and an effective matching of the radiator with the feed that is evident from the results which show that over most of the operating frequencies the return loss is −15dB or less in the plots. The antenna claims its appraisal from the fact that the design only occupies a space of 400mm2 (20mm×20mm) on the single-layered substrate — and a table of comparison is provided in the work, which compares this size reduction of the component with other literature. The article presents the simulated results, and a discussion on how the proposed structure may be utilized in the domain of energy-harvesting — along with a comparison of the work with other reports, to claim the notion of its effective size reduction.

In the last few years, reversible logic gates have been used widely for developing various types of arithmetic and logic processors due to its low power consumption and dissipation. Researchers prefer reversible logic gates for designing several types of optical switching devices in all-optical communication network. The modern high speed network, based on the conventional irreversible logic gates, faces a serious problem of heat generation due to the bit loss at the output, and the basic reason behind it is the unequal number of inputs and outputs. In case of reversible logic gate, the inputs are directly mapped to the outputs and thus, there is no chance of bit loss. Consequently, generation of heat due to bit loss is not possible ideally. In this article, authors have proposed a new technique for developing all-optical Feynman gate which is a simple two-input two-output reversible logic gate. All-optical circuit has been designed using optical polarization switches (PSW), made of Semiconductor Optical Amplifiers (SOA). The working principle is based on the theory of nonlinear polarization rotation of the probe beam in the SOA. Authors have also designed all-optical one bit binary comparator using reversible logic gates. The proposed scheme works on frequency encoded data. As the frequency is the inherent property of the signal, frequency encoded data based logic gates are more preferable for designing arithmetic and logic processor. Simulated results enhance the admissibility of the proposed schemes.

Epilepsy or recurrent seizures is one of the most common non communicable neurological disorder that is prevalent in today's world population are sudden outburst of excess electrical activity of the neurons. Epilepsy can be detected from Electroencephalogram (EEG) as EEG captures and presents the electrical activity of the brain. Non-invasive EEG or scalp EEG is generally used where electrodes are placed on the scalp in order to record the brain activity. In this work a unsupervised machine learning technique is explored which is used to cluster and extract features from EEG recordings (noninvasive) to detect seizures. A patient specific approach is adopted on an open dataset (Physionet database) from where 51 seizure and 51 non seizure recordings of pediatric subjects (age ranging from lyrs to 12yrs) are considered for the related work. Unsupervised algorithm used here is the k-means algorithm to cluster the recordings into two distinct clusters of seizure and non-seizure data. When the performance of the algorithm was tested the algorithm worked with 91.43% accuracy from nearly 18, 00, 000 data taken from various subject. In future scope of work the accuracy of the method can be enhanced using appropriate features for distinctly identifying different intractable seizures according to their characteristics that are prevalent among pediatric patients.

This paper presents liquid level control of interacting spherical tank system using PI controller. The spherical tank is divided into four regions and for each region a particular PI controller is designed. Initially the parameters are tuned using the conventional tuning formulae of Ziegler-Nichols. Although conventional tuning formula gives a good stating solution but it lacks in obtaining all the design requirements. Thus the PI controller is optimized by grey wolf optimizer to enhance the system performance and to achieve the desired time-domain requirements. The results are validated by calculating the performance indices like integral square error. Simulation results validate effectiveness of the proposed scheme as compare to the literature.

An Electron Cyclotron Resonance (ECR) Plasma Enhanced Chemical Vapor Deposition (CVD) setup has been proposed here to create good quality uniform nano-dimensional coating on a large number of concave substrates. Our present objective is to study the wave plasma interaction in a unique ECR plasma enhanced deposition system using COMSOL Multi-Physics Software. The surface electron density and its temperature will be presented in this study by varying the intensity of confining magnetic field. Here two identical deposition chambers are fed by two identical shaped microwave coaxial antennas. In the proposed scheme, high density plasma is generated around the 875 Gauss resonance zone. It is essential for cracking the precursor gas molecules used for the deposition of the film. The study will help us to create nano-dimensional coating of dielectric materials needed for nano devices. This also will facilitate to create a uniform metallic and non-metallic nano films inside the surface of a semi-cylindrical/concave shaped device.

The potential of silicon nanoparticle (Si NP)-polyaniline (PANI) composite as next-generation thermoelectric (TE) material has been investigated in this study. Si NPs, prepared by oxidation-etching-oxidation of milled Si powder was mechanically mixed with PANI, synthesized by oxidative polymerization of aniline. The Seebeck coefficient of dedoped PANI and its composite with Si NPs was remarkably high, but the composite behaved like a perfect insulator making it unsuitable as a TE material. However, the incorporation of Si NPs in protonated PANI showed an improvement in Seebeck coefficient by 1μV/K at room temperature without any major decrement in the electrical conductivity. Protonated PANI-Si NP composites hold immense promise as efficient TE.

Driving under the influence of alcohol not only possesses threat to the driver himself but also endangers the lives of people on the road. To prevent accidents due to drunken driving, a paper is presented on an automated system that detects such situations and adopts measures to avoid it. When alcohol sensor detects certain level of alcoholic concentration, the controller will automatically stops the car and generates alert to the local authorities using Li-Fi and GSM module. The controller also transmits healthy condition of a running vehicle and the local authority is alerted the moment it faces any accident.

All-optical data processing technology has the strong potential to reach the goal of ultra fast data processing for the present and coming generation. But use of conventional binary logic based operation degrades the expected speed because of the limitation of data representation scheme based on only two states. A very promising approach to deal with enormous amount of data with a very high speed is switching to Multi Valued Logic (MVL) from conventional binary logic based operation in the optical domain. In this article the authors have designed all-optical T-gate, a universal gate in quaternary logic system with radix-4, and an all-optical quaternary subtractor have also been developed using the T-gates. The basic building unit used to make these circuits are Semiconductor Optical Amplifiers (SOA). The property of polarization switching and frequency routing properties of SOA have been exploited in the present scheme. Here the authors have encoded every data bit with a particular frequency of an optical signal. The utility of the frequency encoding technique is that the value of frequency encoded data remains unchanged during transmission, and thereby bit error problem can be significantly reduced. The corresponding simulation results hike the acceptability of the proposed scheme.
