The purpose of this research is to analyze the speed of sound variations based on ring a rifle at a distance of 1240 meters at 22 ° C at the sea level in the province of Santa Elena, Ecuador. This is a nonexperimental cross-sectional study based on the data collected from 45 students, in addition, it has a descriptive design, and the measurements were taken using a chronometer during the 8 attempts each participant had. The main focus was the variation of time from the sparks ignition until the sound produced by the gunpowder explosion during each attempt. Instruments to establish meteorological conditions were used in order to measure wind time, distance, temperature, speed, and direction. The data analysis was aimed at determining the individual and general median time of shooting flight, having as a result 351,27 m/s. This value is close to the 350 m/s presented by Galileo Galilei and it remarkably differs from the 372 m/s claimed by Donoso (2013) or the 330 m/s stated by the Military Education and Doctrine Command (2018). This research also aims at contributing to the military field to calculate distances which allow the determination of the enemy´s position or the location of a missing combatant through ring a rifle. Since precision is a key factor in military operations, this investigation may be considered to design a battling field simulator in which distances and direction are calculated through a gunshot.

Abstract MANET nodes are naturally well-known by their limited energy, processing, and memory resources as well as high degree of mobility. In such networks, the mobile nodes may dynamically enter the network as well as leave the network.

MANET nodes are naturally well-known by their limited energy, processing, and memory resources as well as high degree of mobility. In such networks, the mobile nodes may dynamically enter the network as well as leave the network. Due to the restricted transmission range of wireless network devices, multiple hops are usually needed for a node to exchange information with any other node in the network. A joint routing and energy allocation plan is developed which stabilizes the system and provides surrounded average delay guarantees whenever the input rates are within this capacity segment. multipath routing algorithm is proposed for industrial wireless mesh networks for improving reliability and determinacy of data transmission, as well as to effectively deal with link failures. The proposed algorithm adopts the enhanced Dijkstra’s algorithm for searching the shortest route from the gateway to each end node for first route setup. A virtual pheromone distinct from the regular pheromone is introduced to realize pheromone diffusion and updating. This paper considers jointly optimal design of cross layer congestion control, routing overhead and Throughput for Mobile ad hoc networks. Read More Read Less

In the current scenario of a thin client environment the client mostly depends on the cloud or a remote server for most of its computing needs. As a result huge amount of data has to be transferred continuously over the network all the time. In such a case network performance is a severe issue. It is also important to acknowledge that network bandwidth and performance is more critical in any type of cloud-based computing model. If data transfer is taking too much time then irrespective of the cloud technologies that you use, it will not result in performance and user satisfaction. IT organizations spend huge money on dedicated computers and network infrastructure. This project is an attempt to address this problem and come up with some improved solution to manage the network traffic that will result in seamless operation of thin client devices in a virtualized environment. Firstly, we aim to study the factors affecting the network performance in a virtualized thin client environment and then based on this research propose and implement a solution to efficiently address the problems. Also when an organization uses multiple thin client machines for their business the scalability of the system will also be improved by our product. Read More Read Less
