No full textIn this paper, we have proposed a new HNNPSORZLEACH protocol called neural network based particle swarm optimization rendezvous nodes with Leach protocol for the efficient selection of routing. The significant improvement has been shown using HNNPSORZLEACH in comparison with RZLEACH in terms of throughput, dead nodes, alive nodes and remaining energy. Our expectations are demonstrated by simulation results. The exploring ascertains the stable region and maximized lifetime of a network by using HNNPSORZLEACH over RZLEACH.

No full textME-CAD/CAM-DissertationIn this fast growing world everyone is trying to be perfect and want to reach anywhere with as much as less time it takes. So, in the medical field also every patient want to get best treatment with high precision and accuracy. A robotic arm can provide both of them which can be controlled by computers and the inputs given by a specialise doctor sitting on another table or may be somewhere else in the world. The robotic surgery enables surgeons to perform even the most complex and delicate procedures through very small incisions. A robotic surgery provide patient less time to recover, less blood loss.
Designing of manipulator for the considerations of functions it performs, its limitations and motor housing.

A Unified Shell model for Buoyancy-Driven Turbulence
No full textWe construct a unified shell model for stably stratified and convective turbulence. Shell model simulation of stably stratified flow in turbulent regime exhibit Bolgiano-Obukhbov (BO) scaling in which the kinetic energy spectrum varies as . However, simulation of convective turbulence shows Kolmogorov's spectrum. These results are consistent with the direct numerical simulations of Kumar {\em et al.} [Phys. Rev. E {\bf 90}, 023016 (2014)]. We also observe a dual scaling ( and ) for a limited range of parameters in stably stratified flow

Cabin Temperature Control of a Parked Car through Forced Ventilation
No full textM.E. (CAD/CAM Engineering)Temperature level in a car parked under direct sunlight rise up to 30˚C to 40˚C above the atmospheric temperature due to green house effect of solar radiation. Thermal Comfort of the passengers in a car is of major concern for car manufacturers as well as for passenger in peak summer season. Children and pets sometimes left unattended inside a parked car, even for short duration are vulnerable to heat stress and illness. Cooling loads also tend to increase with rapid rise in temperature once the car becomes hot. The material inside the car cabin is more prone to damages due to high temperature.
The main objective of present work is to control the temperature variation inside a parked car by rejecting the accumulating heat with the help of forced ventilation. This report includes the study of temperature variation inside the car cabin, while car is parked for long duration of 5 hours and for short duration of 15 minutes. Temperature variation was recorded with the help of thirteen different temperature sensors placed at different location inside the car cabin. The same was also verified with thermal imaging technique. Maximum temperature reduction is of 11-13 ˚C for cabin air, 24.4 ˚C for dashboard and 23.1 ˚C for the steering wheel. The experiments also found that air conditioner achieve the temperature of 32.7 ˚C in 15 minute from hot cabin at 50 ˚C with the proposed technique, whereas 39.9 ˚C was achieved in 15 minutes from 61 ˚C with the conventional system. The proposed system with auxiliary fans prevent the car cabin from high accumulating heat and facilitates the passenger to enter the cabin at much lower temperature
Dry Abrasion Wear of Windshield Glass and its Effect on Night Driving
No full textWindshield wipers are safety equipment for cars, especially for maintaining clear vision during inclement weather circumstances as rain, snow, or sleet. Windshield glass plays a crucial role in protecting driver visibility and safety, particularly during night-time conditions. Windshield wipers are employed on windshields to clear the windshield of water, snow, grime and other debris so that the driver can see clearly. However, when the glass surface is cleaned with wipers, continuous exposure to various external variables, such as dust, sand, etc., can result in the formation of dry abrasion wear. Motive of present research is to examine; how dry abrasion wear affects windshield glass and its effect on night-time driving. In the past, numerous studies demonstrating windshield wear have been conducted, but none in India, where the amount of dust and debris in the air is more than in other nations. Additionally, no studies have looked into windshield wear under actual environmental conditions.
The wearing of windshield glass and its effect on visibility at night have been examined through a number of tests. A proper setup with a functioning wiper mechanism was designed to abrade the windshield with the dust accumulated in natural environmental conditions. Different wear regions on the windshields were identified and high-resolution night photography was carried out to observe the impact of windshield wear during night-time driving. To assess windshield wear, the roughness of the windshield glass was also tested. Using the EDS method, the constituents of the dust that was deposited on the windshield glass were also assessed.
The findings from the experiments shows that dry abrasion wear has a substantial impact on the windshield glass surface and increases light scattering at night. It is also verified that as the number of wiper cycles on the windshield increases, the wear increases, i.e., the scattering of light is greater in the regions where the wiper cycles are higher. Another important finding reveals that new wiper blade damages the windshield glass more than the old wiper blade, as it has a better area of contact

Multivariate Quantitative Representativeness and Constituency Analysis of Ecological Observation Networks
Author: Jitendra (Jitu) Kumar ([email protected]), Oak Ridge National Laboratory
Regional and global ecological research networks, representing coordinated and standardized as well as adhoc networks of observation sites, provide valuable observations necessary for ecological modeling and synthesis studies. Studies conducted across observational networks strive to scale up their results to larger areas, trying to reach conclusions that are valid throughout regional, continental, and even global scales. Network representativeness and constituency can show how well conditions at those locations represent conditions elsewhere within a larger area containing the network and can be used to help scale-up results over larger regions.
Representativeness: Euclidean distance between two sites plotted in multivariate environmental space can be used as an inverse measure of multivariate similarity to quantify representativeness. Close sites in environmental space have a similar combination of environmental factors, and therefore are highly representative of each other.
Constituency: For any site in the network, its Constituency represent all locations that are best represented by the multivariate environmental drivers at that site.
