This study introduces a method for formation control and obstacle avoidance for multiple unmanned surface vehicles (USVs) by combining an artificial potential field with the virtual structure method. The approach involves a leader–follower formation structure, where the leader autonomously avoids collisions using an artificial potential field based …

The radial potential distribution in an ionic beam of circular cross section is calculated and the maximum beam current which can be obtained in a beam of given radius and boundary conditions is computed. In the case of ions the maximum beam currents may be quite small. The ions in such beams have a considerable velocity distribution which in turn leads to a …
The 4-2-2-2 formation can be less flexible tactically than other formations, as it may be harder to change the team's shape during the game without making significant substitutions. How to Counter 4-1-2-1-2 Formation? Exploit the flanks: Since the 4-2-2-2 formation can be vulnerable to attacks from the flanks, opposing teams can focus their ...
Introduction. Spatiotemporal variation of upwelling circulation over a continental shelf can be induced by various forcing mechanisms. It is well known that the presence of alongshore topographic variations on an otherwise relatively straight continental shelf has a profound influence on coastal upwelling circulation (Lentz et al., 1999, Gan …
Methods for accommodating the disturbance due to the J 2 by modification of the relative orbit initial conditions are discussed and examples provided include multi-impulse optimal formation initialization maneuvers and a novel inter-satellite fuel balancing concept. This chapter presents continuous and impulsive control methods for formation initialization, …

The formations tend to break down because of various disturbances such as J2, and must be maintained by application of thrusts which require fuel. On-board fuel is a scarce commodity in space; hence, there have been some efforts to develop propellant-free formation maintenance schemes using solar radiation pressure (SRP) and/or …
Machining of modern materials requires high performance tools. More than 60% of metal cutting tools used are coated to limit abrasive wear. As the harder material known to man, diamond and consequently Chemical Vapour Deposited (CVD) diamond coatings allow to increase performances of tungsten carbide tools, i.e. tool life, …
In this paper, we introduce distance-based control laws for the multi-agent formation maintenance and target tracking problems. Using a single-integrator agent model, the proposed controls consist of a formation acquisition term, dependent on the potential function and graph rigidity matrix, and a formation maintenance or target …
