Measurements of atmospheric temperature, pressure, water vapor, and composition are important to users in the Earth science, defense, and intelligence communities. Nanosatellites (with mass < 10 kg, such as CubeSats) can support miniaturized instruments for atmospheric sounding and characterization. Nanosatellite constellations can improve spatial and temporal weather sensor coverage of Earth a...

A multicenter double-blind placebo-controlled study of cytidine 5'-diphosphocholine (CDP-choline) was conducted to evaluate possible clinical benefits of the drug in patients with acute, moderate to severe cerebral infarction. The patients included also suffered from moderate to mild disturbances of consciousness, and all were admitted within 14 days of the ictus. Patients were allocated random...

Based on the concept of free energy, we give a Hamiltonian formulation for the torsion dynamics of macromolecules. The appropriate reaction coordinates for the free energy calculations are deened in terms of soft constraints as introduced in 3] and 14]. We consider a few simpliications that allow one to calculate the free energy analytically and to write the corresponding equations of motion as...

Fractional step (or projection) methods are a widely used technique for uncoupling the pressure solution in the incompressible Navier-Stokes equations while still satisfying the incompressibility constraint. Traditional fractional step methods have a time splitting error that can become quite significant if any of the terms in the momentum equation are treated implicitly. Higher order splitting...

The Washington University in St. Louis IEEE student branch are designing a next-generation LED dance floor that synthesizes color, music, and touch in a way that has not been done in any other device. The device is being designed with modularity and expandability as key features and therefore a solid, reliable power system was needed. This report focuses on the project’s power distribution and ...

This paper addresses the problem of calibrating a pinhole camera from images of a surface of revolution. Camera calibration is the process of determining the intrinsic or internal parameters (i.e., aspect ratio, focal length and principal point) of a camera, and it is important for both motion estimation and metric reconstruction of 3D models. In this paper a novel and simple calibration techni...

Analyses for columbium in pyrochlore ores from North Bay, Ontario, have been made successfully by using o-ray fluorescence techniques. rt was necessary to use, as in methods of optical spectroscopy) an internal standard for this work. The choice of a suitable internal standard for a particular metal in a specific mineral association or ore-t).pe requires consideration of the characteristic r-ra...

We address the determination of the second point-to-point shortest simple path in undirected networks. The effective reduced cost concept is introduced to compute the second best solution. This concept is used to prove that a path tree containing the second point-to-point shortest simple path is adjacent to any shortest path tree. Therefore, this result immediately implies a methods requiring O...

In this paper we present a methodology for the evaluation of networked systems communicating using WLAN technology. We show a case study of goal-oriented cooperating robots, for which our approach is particularly useful. Developing robots is expensive; hence emulation can be employed in the first part of the development cycle to study robot software implementations in realistic conditions at a ...

The Input Validation Testing (IVT) technique has been developed to address the problem of statically analyzing input command syntax as de ned in English textual interface and requirements speci cations and then generating test cases for input validation testing. The technique does not require design or code, so it can be applied early in the lifecycle. A proof-of-concept tool has been implement...
