Aim: To assess the visibility, frequency and gender variations of mandibular canal, mental foramen, anterior loop nerve, incisive canal lingual foramen in Indian population. Material Methods: Retrospective analysis total 300 panoramic radiographs were selected for study. Radiographs analysed by two independent observers scores recorded. Intra inter-examiner reliability was assessed kappa-statistics percentages observations obtained Chi-square test used to find out association age with...
Most of the communications in century is accomplished through wireless medium.There are various standards for simultaneous running different applications.WLAN (Wireless Local Area Network) a common communication standard.Among five bands announced by IEEE 802.11 LAN, two most 2.4 GHz and 5.2 GHz.In this paper, an antenna designed WLAN applications.To remove problem mismatching at coaxial feeding, approach improving matching performance studied.The requirement impedance matching, gain...
Abstract Introduction: Expanding knowledge on tobacco use and quitting outcomes in Chhattisgarh, India, is crucial. Limited data hinder the assessment of prevalence region. This household-based cross-sectional study aimed to assess smokeless (SLT) quit behaviour among village dwellers aged 35–44 65–74 years Jamul, Chhattisgarh. Materials Methods: A survey was conducted 450 participants, utilising a pretested questionnaire analysis using IBM Statistical Package for Social Sciences (SPSS) v23....
Grid modernization is a critical component in transforming today's electric, gas, and water utilities to meet the growing expectations of regulators customers. integration use connected devices from customer premises rest transmission distribution networks. The are meters, monitoring equipment, controllers that allow utility employees remotely access data operate network. These backbone enables electric improve reliability, maximize operational efficiencies, accommodate increasing...
The noise characteristics of semiconducting BaSrTiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> were investigated as a function frequency, bias current, and volume the sample.

A light-weight pocket-sized microwave monitor for the indication of dangerous power levels received by operators has been developed with considerable sensitivity using suitable BaSrTiO3 to small temperature changes a frequency-independent Ge-film absorber.
A miniature battery-operated microwave power monitor is described which operates across the threshold range of biologically dangerous levels with approximately frequency-independent characteristics up to about 100GHz. CMOS circuitry causes an alarm signal occur, or enables one integrate total energy received over a given period on basis thermal change resistance in thin Ge film due absorption.
Hysteresis feedback controlled synchronous buck converter-based power supply is designed and developed for biasing the transistors of Solid State RF Power Amplifier (SSPA). Design verification done using PSIM software. The requirement SSPA varies from a few watts to 12 kW depending on application. It requires have constant voltage variable current. A comparative study fixed frequency pulse width modulated (PWM) converters hysteresis control converter has been done. advantages challenges...
The high-power radio frequency source for ion cyclotron heating and current drive of ITER tokamak consists two identical 1.5 MW amplifier chains. These chains will be combined using a wideband hybrid combiner with adequate coupling flatness, phase balance, return loss, isolation response to generate 2.5 (RF) power in the range 36 60 MHz. As part in-house development program at ITER-India, flatness loss/isolation better than 0.4 −25 dB, respectively, has been simulated. A detailed analysis...
D2D communication is going to be the upcoming technology which change era of wireless networks due its flexibility. Due limited availability Spectral resources, co-channel interference increasing. Co- channel occurs when number User Equipment (UEs) share same frequency block or commonly known as Resource Block (RB). Many researchers have ideated different Allocation (RA) algorithms using modern optimisation methods like Fuzzy Logic, Game theory, Graph colouring and clustering. RA helps...
