Abstract An early stage detection of Parkinson's disease (PD) is crucial for its appropriate treatment. The quality life degrades with the advancement disease. In this paper, we propose a natural (time) domain technique diagnosis PD. proposed eliminates need transformation signal to other domains by extracting feature electroencephalography signals in time domain. We hypothesize that two inter‐channel similarity features, correlation coefficients and linear predictive coefficients, are able...

Abstract Humans spend a significant portion of their time in the state sleep, and therefore one's’sleep health’ is an important indicator overall health individual. Non‐invasive methods such as electroencephalography (EEG) are used to evaluate ’sleep well associated disorders nocturnal front lobe epilepsy, insomnia, narcolepsy. A long‐duration repetitive activity, known cyclic alternating pattern (CAP), observed EEG waveforms which reflect cortical electrical activity during non‐rapid eye...

Abstract Dielectric resonator antennas (DRA) are advantageous due to their small size, high radiation efficiency, ease of excitation, and minimal metallic losses. Enhancing the gain DRA will make them suitable for a variety applications such as wireless communication technology. High-gain required overcome difficulties path loss.

ABSTRACT This article presents a novel circularly polarized stacked dielectric resonator antenna (DRA) featuring etched slots arranged in an L‐pattern within the ground plane. An analysis of current distribution on plane reveals that inclusion these results formation two distinct paths. This, turn, leads to measured resonances: one at 6.3 GHz corresponding fundamental mode, and another 7.8 higher order . The DRA is composed discs made material with = 9.8, separated by air gap. upper disc...

Ambient backscatter communication (AmBc) is a modern technique that permits smart devices to transfer data with the aid of ambient radio frequency (RF) radiation. This letter investigates issue eavesdropper (ED) attacks on multi-tag AmBc systems. In particular, we explore realistic scenario in which both reader and ED are motion analyze influence their system's secrecy performance when channel estimation imperfect.

Sleep is an essential criterion for health. However, sleep disorders degrade the quality. Hence, to diagnose disorders, monitoring crucial. The cyclic alternating patterns (CAP) phases describe CAP detection a time-consuming, hectic, and uncertain process. Therefore, automatic of necessary. This study proposes hierarchical approach identify classify phases. Single-channel EEG recording provided by database has been utilized in this study. proposed classifies sequence into healthy or...

Thispaper reviews computational techniques to efficiently represent, analyse and visualise both shortterm long-term temporal variation in video image sequences. This paper reveals videos that are imperceptible the naked eye. The method takes a standard sequence as an input, applies spatial decomposition, followed by filtering frames which is called “Eulerian Video Magnification”. resulting signal then amplified reveal hidden information. Paper contains four are: 1.Linear approximation...

With the expanding usage of electronic devices such as smartphones and smartwatches in daily life, need for advanced Integrated Circuits (ICs) is also increasing. Corporations are compelled to outsource IC design production several third-party vendors keep up with demand. This has allowed adversaries make unauthorized modifications circuits. As a result, malicious have been able deploy Hardware Trojans (HTs), similar software viruses, they may cause data leakage circuit disruption. The...

In the performance evaluation of ambient backscatter communication (AmBC) system energy harvesting (EH) by passive tags has been mainly overlooked.
