OBJECTIVE The purpose was to determine if Soldier rucksack load, marching distance, and average heart rate (HR) during shooting affect the probability of hitting the target. BACKGROUND Infantry Soldiers routinely carry heavy rucksack loads and are expected to engage enemy targets should a threat arise. METHOD Twelve male Soldiers performed two 11.8 km marches in forested terrain at 4.3 km/h...

A high-order accurate method for the numerical solution of the incompressible Navier-Stokes equations is developed. Fourth–order, explicit, finite difference schemes on staggered grids are used for space discretization. The explicit, fourth–order Runge–Kutta method is used for time marching. Incompressibility is enforce for each Runge–Kutta stage either by a local pressure correction, which is ...

We consider the problem of partitioning an area in the plane populated by a team of aerial/marine vehicles into a finite collection of non-overlapping sets. The sets of this partition are in an one-to-one correspondence with the vehicles under the following rule: Each point in the given set of the partition can be reached by the corresponding vehicle in this set faster than any other vehicle in...

Kurzfassung. Die Erkennung von mikrobiellen Gefahrensignalen durch Makrophagen führt zu ausgeprägten Veränderungen des Zytoskeletts. Die daraus resultierende morphologische Veränderung (Spreading) führt zur Variation der Kontaktfläche zwischen Zellen und Oberflächenmaterial. Bisher wird die Vermessung durch manuelle Annotation einer jeden einzelnen Zelle durchgeführt. Dieser sehr zeitaufwendige...

The objective of this paper is to provide an ef®cient and reliable algorithm for representing and evaluating the boundary of the interval Be Âzier curve in 2-and 3-D. The boundary of the planar Be Âzier curve is represented by a sequence of Be Âzier curve segments with same degree and line segments in the order they are encountered when marching counterclockwise along its boundary. The boundary...

We present a space-time certified reduced basis method for long-time integration of parametrized noncoercive parabolic equations with quadratic nonlinearity. We first consider a finite element discretization based on discontinuous Galerkin time integration and introduce associated Petrov-Galerkin space-time trialand test-space norms which yields optimal and asymptotically mesh independent stabi...

Implicit surfaces in 3D geometric modeling are limited to two manifolds because the corresponding implicit fields are usually defined by real-valued functions which bisect space into interior and exterior. We present a novel method of modeling non-manifold surfaces by implicit representation. Our method allows discontinuity of the field function and assesses the special meaning of the locus whe...

We introduce a new and efficient numerical method for multicriterion optimal control and single criterion optimal control under integral constraints. The approach is based on extending the state space to include information on a “budget” remaining to satisfy each constraint; the augmented Hamilton-Jacobi-Bellman PDE is then solved numerically. The efficiency of our approach hinges on the causal...
