Questionnaire based study of drivers’ error and violation at four-legged signalized intersection

Abstract: It is an enduring challenge to know the underlying determinants (factors and actors) for developing safe roads from the driving behavior perspective. Human (driver) errors and violations are genera...

Pharmaceutical Perspective in Wearable Drug Delivery Systems

Abstract: Humans have been dealing with health problems for millions of years. Normal health services need well-trained personnel and high-cost diagnostic tests, which forces patients to go to hospitals if medical treatment is required. To address this, prototype testing has been carried out into the wearable drug delivery health care perspectives. Researchers have devised a wide variety of formulations for the treatment of various diseases at home by performing real-time monitoring of different routes of drug administration such as ocular, transdermal, intraoral, intracochlear, and several more. A comprehensive review of the different types of wearable drug delivery systems with respect to their manufacturing, mechanism of action and specifications has been done. In the pharmaceutical context, these devices are technologically well-equipped interfaces for diverse physicochemical signals. Above mentioned information with a broader perspective has also been discussed in this article. Several wearable drug delivery systems have been introduced in the market in recent years. But a lot of testing needs to be conducted to address the numerous obstacles before the wearable devices are successfully launched in the market.

Effect of Current on the Characteristics of CuNi-G Nanocomposite Coatings Developed by DC, PC and PRC Electrodeposition

Abstract: Copper–nickel (CuNi) and graphene nanoplatelet-reinforced CuNi (CuNi-G) nanocomposite coatings were prepared on the surface of stainless-steel substrates in a citrate bath using direct current (DC), pulse current (PC), and pulse reverse current (PRC) electrodeposition techniques. The effect of various electrodeposition currents on the morphology, composition, contact angle, microstructure, microhardness, and wear performance of the coatings were studied. Substantial changes in the surface morphology and microstructure of CuNi-G nanocomposite coatings were observed. The results show that the incorporation of G significantly enhanced the microhardness and wear resistance of electrodeposited coatings. PC and PRC electrodeposited CuNi-G nanocomposite coatings show higher microhardness and wear resistance than DC electrodeposited coatings because of smaller crystallite size, higher content of G, and lower surface roughness.

Predictive torque control of a three-level reduced switch inverter fed induction motor drive

Abstract: The aim of this research work is to evaluate and compare the performances of the Direct Torque Control (DTC) and Predictive Torque Control (PTC) algorithms both applied to a three phase induction motor drive fed by three level reduced switch VSI. The comparison has been made based on the torque and current ripples, settling time, and response times during speed and load disturbances and Total Harmonic distortion (THD). The algorithms are simulated using Matlab/Simulink and the results are presented. It is observed that the implementation of PTC scheme yields better performance with reduced torque ripple than DTC.

Performance analysis of optical burst switching (OBS) network using fiber delay line: A simulation approach

Abstract: One of the key problems in the application of optical burst switching (OBS) network is to overcome the performance degradation due to contention Contention takes place when two or more incoming bursts are directed to the same output line This problem can be solved in time domain by incorporating fiber delay lines (FDLs) in the switch architecture In the present paper a mathematical model has been proposed to estimate the blocking probability of an OBS network in presence of FDLs The proposed work has further been extended to find out the effect of fiber non-idealities on the performance of OBS network The performance of the proposed model has been evaluated using MATLAB simulations Simulation results demonstrate that significant performance gains in optical-burst switching are achievable when FDLs are employed as optical buffers for contention resolution
