 | Right now a Marine Expeditionary Unit (MEU) commander is debating how to support his mission with the right mix of personnel and equipment. In the process, he will seek input from critical staff members who are considered the duty experts in their respective fields. His responsibility is to anticipate questions his commander may pose and have solutions prepared. When it comes to fires, he may find more questions than answers. ... |

|
| We derive analytical results for a dynamic load balancing algorithm modeled by the heat equation. The model is appropriate for quickly diffusing disturbances in a local region of a computational domain without affecting other parts of the domain. The algorithm is useful for problems in computational fluid dynamics which involve moving boundaries and adaptive grids implemented on mesh-connected multicomputers. The algorithm preserves task locality and uses only local communication. Resulting ... |

Jian-Guo Liu; Roger Samelson; Cheng Wang; OREGON STATE UNIV CORVALLIS COLL OF OCEANIC AND ATMOSPHERIC SCIENCES
|
| A reformulation of the planetary geostrophic equations (PGEs) with inviscid balance equation is proposed and the existence of global weak solutions is established, provided that the mechanical forcing satisfies an integral constraint. There is only one prognostic equation for the temperature field and the velocity field is statically determined by the planetary geostrophic balance combined with the incompressibility condition. Furthermore, the velocity profile can be accurately represented as a functional ... |

Manuel Gamero-Castano; BUSEK CO INC NATICK MA
|
| We describe the performance of a torsional balance suitable for the study of microNewton thrusters. A design based on flexural pivots and electrostatic forces (for calibration and active damping) makes it possible to test thrusters with a mass of a few kilograms, and measure sub-microNewton level forces with high accuracy and a resolution better than 0.03 micro N. The usefulness of the balance is proved by measuring the performance of ... |

|
| In 1993, Scherpen generalized the balanced truncation method to the nonlinear setting. However, the Scherpen procedure is not easily computable and has not yet been applied in practice. The authors offer methods, tools, and algorithms for computing the energy functions and coordinate transformations involved in the Scherpen theory and procedure for nonlinear balancing. They then apply their own approach to derive, for the first time, balanced representations of nonlinear state-space ... |

| Two-legged and four-legged walking are the most versatile forms of land locomotion in the sense of maneuverability and the ability to traverse irregular terrain. Unfortunately, the problem of practical bipedal walking with dynamic balance has so far eluded solution using classical and other control techniques. We have been investigating the use of neural networks for on-line gait modulation during walking, using a 10 degree-of-freedom biped robot and a 20 degree-of-freedom ... |

| The purpose of this work was to develop a controller that could perform the highly discontinuous and nonlinear task of balancing the inverted pendulum from an arbitrary set of initial conditions. Fuzzy logic was chosen as the control technique because of its ability to deal with nonlinear systems, as well as its intuitive nature. The rule base depends on intuition and logic, rather than an exact mathematical model. This makes ... |

|
| The overall mass balance of the Antarctic ice sheet has been estimated by comparison of the best available data on input in the form of snowfall with output in the form of ice flux through gates at or near the margin of the ice sheet. Surface melt is a negligible contributor to mass balance and has been ignored. Bottom melt under large ice shelves remains a major source of uncertainty. ... |

|
| The onset of global warming from increasing greenhouse gases in the atmosphere can have a number of important different impacts on the Antarctic ice sheet. These include increasing basal melt of ice shelves, faster flow of the grounded ice, increased surface ablation in coastal regions, and increased precipitation over the interior. An analysis of these separate terms by ice sheet modeling indicates that the impact of increasing ice sheet flow ... |

|
| We have been studying how to use compartmental models to reliably extrapolate toxicological experiment results from one animal species to another with the ultimate goal of useful extrapolation to man. We have taken as the fundamental core of our analysis the physically necessary equations of the form VaC/dt = Q(a-v). These equations are not a complete set since they are insufficient to provide estimation of venous arterial or tissue concentrations ... |

| Deterrence of war in Europe or, if necessary, its successful prosecution- is a key goal of U.S. defense strategy. Achieving that goal depends in part on the balance of conventional forces between the United States and its allies in the North Atlantic Treaty Organization (NATO) and the Soviet Union and its Warsaw Pact allies. (Conventional forces include all military forces other than those employing nuclear weapons.) Assessments of the conventional ... |

| The objective of this study was to determine the feasibility of stabilizing an ARES 90mm gun on a 22-ton class combat vehicle. Since the major difference between the ARES gun and other guns currently on combat vehicles (from a stabilization point of view) is the large unbalance, this study is primarily concerned with the effect of the unbalance. The primary phenomenon of concern is acceleration's act on an unbalanced gun ... |

Balancing is treated as an optimization problem suitable for computational solution. Techniques are considered which permit the magnitude of the balance weights chosen to lie within practical bounds. One method will suppress the rotor response at speeds higher than those that can be safely negotiated without balancing. An approach is developed for ... |
