14 Mar 2013TL;DR: A study on national animal reserves is made and an efficient monitoring approach for tigers using wireless sensor network based on hotspot algorithm to preserve the wild species is proposed.
Abstract: In recent years, ecological monitoring is given more importance to preserve the various species in the environment. Wildlife monitoring gradually progressed with the developments in Global Positioning System (GPS) and wireless sensor communication. In this paper, a study on our national animal reserves is made and reviewed papers related to animal tracking. Also the paper proposed an efficient monitoring approach for tigers using wireless sensor network based on hotspot algorithm to preserve the wild species. This system can be used by the ecologists to track and monitor various parameter of the wild species to preserve the habitats.

11 Feb 2020TL;DR: The trust stage computation of range and KNN query answers is exposed with the help of the whale optimization algorithm (WOA) and the effectiveness of the proposed concept is evaluated through various consequences.
Abstract: Generally, human and machine-based query operations can be modified with the use of crowdsourcing. Location-based queries are classified into range and k-nearest neighbor (KNN) queries. Space and point of interest (POI) information can be obtained from both range and KNN queries. In this paper, we expose the trust stage computation of range and KNN query answers with the help of the whale optimization algorithm (WOA). The system chooses either parallel or serial processing, and the experiments are carried out using real-time crowdsourcing. The effectiveness of the proposed concept is evaluated through various consequences such as gang dimension, POI information, space information, and range and KNN query consequences. Each of these effects produces an optimal and reliable result. Finally, the computation time and communication overhead performance of serial and parallel processing are analyzed by examining consequences and production of optimal outcomes.

TL;DR: In this article, the authors have taken two types of CD nozzle configuration (circular and elliptical throat) and it is studied for various NPR ratios of 2, 3, 4 and 6.
Abstract: Abstract The acoustic and flow characteristics of a jet with elliptical throat is studied at different levels of nozzle expansion ratio. In this study, we have taken two types of CD nozzle configuration (circular and elliptical throat) and it is studied for various NPR ratios of 2, 3, 4 and 6. In addition, the acoustic characteristic of the jet flow is also measured for respective NPRs. Measurements of acoustic data are done using microphones placed at 30, 60 and 90 degrees to imprison the effects of screech tone. At NPR 2, 3 and 4, the jet with elliptical throat witnesses superior mixing and shorter core length compared to the circular throat. Its surprising to see both the configurations provides the identical oscillation at NPR 2, 3 and 4, however the efficiency of jet mixing is larger in elliptical throat jet. As the nozzle pressure ratio increased from 2 to 3 and 3 to 4, the potential core length of the jet reduces marginally about 5 to 10 % for every NPR until nozzle pressure ratio of 5. At NPR 2 and 3, the centerline pitot pressure profile shows, the decay of jet from the elliptical throat is healthier than a circular jet. At various levels of nozzle expansion, shock cell shows an appreciable change with an increase in NPR. Introduction of the elliptical throat on circular modifies the structure of shock cell which significantly changes the magnitude of screech tone due to the weakening of shock waves.
