This paper presents a technique, Probabilistic Road Map (PRM) planning and its application to aircraft for rapidly generating routes using aggressive maneuvers to avoid incoming munitions, terrain, and other aircraft while trying to maintain other mission objectives. The technique was applied to a high fidelity simulation and shown to always generate correct routes within its 0.1 seconds deadli...

Severe constraints apply to the architecture of any system which uses large numbers of components to deliver complex functionality. If not taken into account, these constraints can invalidate conclusions drawn from simulation of cognitive subsystems. The pattern extraction hierarchy is a connectionist architecture which can satisfy these constraints. Within the architecture, functionality is pa...

This article investigates the performance of the heterodyne detection scheme for optical pulse-position modulation (PPM) communications channels when nonideal laser transmitters are employed. Two aspects of this channel will be considered. First, the limitations of unguided, turbulent channels in accommodating coherent laser communications are addressed. This is followed by an investigation of ...

This paper proposes a CNN cascade for semantic part segmentation guided by pose-specific information encoded in terms of a set of landmarks (or keypoints). There is large amount of prior work on each of these tasks separately, yet, to the best of our knowledge, this is the first time in literature that the interplay between pose estimation and semantic part segmentation is investigated. To addr...

Abstract: This paper investigates the trajectory prediction and dispersion for unguided fin stabilized artillery rocket in order to explain the importance of the rocket production accuracy and the benefit of using guided rockets. The total dispersion results mainly from three effects. The first is the dispersion due to rocket production inaccuracy, which includes propellant mass, composition in...

Since the 2001 terror attacks in the United States, counter-terrorism strategies have become a security priority for many nations. More recently, the upsurge of ‘home-grown’ extremists and those returning home from foreign conflicts represents a significant risk to public safety. Unfortunately, the pre-identification of would-be terrorists is an extremely difficult task for law enforcement, esp...

Mobile Ad-hoc Network (MANET) is type of unguided network whose nodes are self-configuring and connected by wireless links. Anonymity communication is one of the major issues in MANET. Many anonymity enhancing techniques have been introduced based on packet encryption. These were designed for the protection of communication anonymity in mobile ad hoc networks. However, passive statistical traff...

We study the motion of a cylindrical particle translating slowly in a long tube as a function of the particle's dimensions and placement both in the presence and the absence of external pressure gradients. The cylinder acts as a "leaky" piston, generating both fluid recirculation and through flow. When the particle is long, analytic expressions are obtained for both the velocity field and the f...
