“…Underwater acoustic channel has been modeled as a five path Rayleigh fading channel for most of the simulation experiments. Time variant fading is incorporated and additive white Gaussian noise (AWGN) is introduced [8,9]. In the process of simulation multiplicative fluctuation of each individual path is realized by including a time variant and correlated fading factor in the signals amplitude or the power.…”

There is an ever felt need to create an efficient comprehensive system to tackle natural hazards such as Tsunamis, earthquakes, landslides and floods by providing a timely early warning. Underwater wireless sensor network (UWSN) seems to be one promising solution. The success of mobile wireless communication in terms of power efficiency and reliability needs to be repeated with the UWSN for fighting the havoc of nature. An integrated system for early warning generation which would provide information globally is proposed. This paper highlights the physical layer challenges in establishing a reliable, low power consuming and long life UWSN system for early warning generation.

“…Over the past two decades, much research has been conducted to characterize target impact dispersion. In general, a wide range of ammunitions, including large-, medium-, and small-caliber projectiles, along with a few different weapon systems, including air guns and electromagnetic guns, has been covered for dispersion study [1][2][3][4]. Most investigations focused on dispersion analysis of experimental data for a particular weapon system.…”

This study quantifies the contribution of variant projectile velocity at a gun muzzle to its dispersion at an aim point from an analytical approach. The dispersion was formulated on the basis of stochastic physical conditions including potential crosswind effect. As a result, the statistical quantities of projectile impact distribution could be obtained from the stochastic formulation. In addition, this research proposes correction factors that may be needed when comparing dispersion in angular mil at multiple downrange distances. The significance of the correction factors was demonstrated through a few applicationBallistic dispersion is one of the important metrics that has been used to assess the performance of a weapon system. Over the past two decades, much research has been conducted to characterize target impact dispersion. In general, a wide range of ammunitions, including large-, medium-, and small-caliber projectiles, along with a few different weapon systems, including air guns and electromagnetic guns, has been covered for dispersion study [1][2][3][4]. Most investigations focused on dispersion analysis of experimental data for a particular weapon system. Some published research discussed ballistic dispersion with the consideration of a predefined physical condition from external environment, and others addressed the phenomenon with the demonstration of computer modeling and simulations [5,6].Conventionally, the absolute value of dispersion was initially computed based on a number of rounds at a certain range. Then, the dispersion quantity was divided by tbe corresponding downrange distance to obtain the dispersion in angular mil. This dimensionless unit enables us to compare dispersions at two or more different downrange distances. This comparison of dispersion at multiple distances is valid under the assumption that the projectile flies in a vacuum space. In other words, no external factor is considered in the calculation. Thus, one of the objectives of this study is to formulate the random nature of round-to-round errors in consideration of several varying environmental factors and evaluate if the underlying assumption for the conventional dispersion calculation is appropriate when some external forces are taken into account during flight. This analytical approach links dispersion results to projectile initial velocity conditions or vice versa from a theoretical point of view. When one of these two measurements is available, the other quantity could be derived accordingly. The proposed formulas in this study may be utilized to facilitate performance assessments of weapon systems.This investigation begins with the introduction of the most simplistic case, one where no external force is applied on a projectile during flight. That is, the initial conditions of the projectile at the muzzle remain the same throughout the entire flight period. It has been observed from many experiments that the target impact points (TIPs) were randomly distributed even when the same ammunition and weapon types were fired....
