This Note reports an initial investigation of individual differences in planning. Studying how individuals differ in their approach to planning may help us to understand the cognitive activity that underlies the development of a good plan and the factors that limit planning effectiveness, as well as producing prescriptive guidelines for improving planning. The research focuses on the analysis of thinking-aloud protocols produced by five subjects as they performed a set of errand planning tasks,...

The report analyses by means of examples the applicability of the finite element method (in the form of a weighted residual approach) to hyperbolic equations, using rectangular elements and bi-linear, bi-quadratic or bi-cubic shape functions. For sinusoidal initial conditions the errors are discussed for semi and fully discretized approximating equations. All methods have appreciable errors if the wave lengths are short. For semi-discretized methods, higher order elements give more accurate...

Reynolds numbers for transition on a flat plate measured in two brief series of tests in the RAE 4 ft x 3 ft tunnel with two different screen arrangements in the settling chamber are presented. In the two series the transition Reynolds number varies in magnitude in opposite senses with tunnel speed but the same trend is indicated for the variation with turbulence level. At the lowest level of turbulence achieved, the transition Reynolds number approaches 6 million, and according to Mack's...

Analysis of data from more than 21,000 soldiers measured in U.S. military anthropometric surveys since 1966 indicates that 0.47% exceed the upper limits of fit for the size Large PASGT helmet in one or more head dimensions. Although this frequency is relatively low, it suggests that at least 3,650 individuals in the active duty Army may be disaccommodated by the current PaSGT sizing system, and that a size Extra-Large helmet will be needed if all soldiers must be fit within the system.

By the 1850s, the Victorians had developed a deep-seated ambivalence toward heroes and heroism. Rapid changes in society, religion, and culture compelled some writers to search for new heroes, while other writers questioned whether the hero could exist in the modern world. Mid-Victorian authors, drawing on or reacting against classical, chivalric, and Romantic models, revealed their society's paradoxical feelings on this subject. Anthony Trollope's Barsetshire novels also reflect this Victorian...

In recent works we have formulated a new approach to compressible flow simulation, combining the advantages of shock-fitting and shock-capturing. Using a cell-centered Roe scheme discretization on unstructured meshes, we warp the mesh while marching to steady state, so that mesh edges align with shocks and other discontinuities. This new algorithm, the Shock-fitting Lagrangian Adaptive Method (SLAM) is, in effect, a reliable shock-capturing algorithm which yields shock-fitted accuracy at...

Filament-wound fiberglass has been recognized for some time as a potential structure for storing fluids under pressure in a cryogenic environment. The highest potential is realized with a thin, smooth-bonded, metallic liner. The number of cycles that can be achieved with such a liner, however, is dependent upon the ability of the adhesive to prevent the liner from buckling and upon the ability of the liner to resist fracture when subjected to high, plastic, tensile-compressive strains. The goal...

Considering the importance that stress has in the armed forces, it is necessary to study those factors that reduce the probability of apparition of it. From the prevention point of view, the studies show different factors that can reduce the negative impact of this phenomenon (Distress). Among these factors, morale plays a fundamental role. Since Spain began in 1988 its participation in operations of peace and human aid, by mandate of the UN, to our days, we can verify the increase of the same...

Other details of the dielectric properties apparently depended on interaction of transverse moisture gradients with other variables in the kiln and in the electrical instruments.

Ammonium nitrate (AN) is a possible replacement for ammonium perchlorate as an oxidizer in solid rocket motors potentially generating large amounts of AN to be recycled or reused. AN requires phase stabilization before it can be used, so small amounts of potassium dinitrimide (KDN) are added to create phase stabilized ammonium nitrate (PSAN). Reuse alternatives would either require separating the KDN or destroying it. AN is commonly used as a fertilizer (80 percent of AN produced) and an...

The key transcriptional regulators of the cellular hypoxic response, Hypoxia Inducible Factor-1 (HIF-1) and NF-kB, are responsible for induction of genes that regulate anaerobic metabolism, cell survival, and angiogenesis. We hypothesize that cancer cells subvert these normal hypoxia-dependent mechanisms to enable their own deregulated survival, neovasculogenesis, and growth. We find that loss of the p53 tumor suppressor gene promotes the neovascularization and growth of tumor xenografts. Our...

The energy requirements of technologies today are more demanding than ever. The requirement for large energy storage and a quick release of that energy is becoming a greater and greater problem. Limited by size, cost, and the speed of chemical reactions, batteries need to be replaced as a primary source of stored energy. Capacitors have the ability to perform in many of the areas where batteries and other energy sources fall short. One way to increase the performance of a capacitor is by...

In applications of electrically short antennas such as multiturn loops, variation in ohmic losses due to proximity effects can significantly affect uncorrected estimates of efficiency. The paper investigates experimentally the proximity effects on the current distributions and associated ohmic losses for two identical parallel rectangular cross-section conductors as a function of separation distance and cross-section. The system is operated in a non-transmission-line mode. In the light of...

A technique for interpolating an irregularly sampled multidimensional field is presented. The method assumes that the field to be interpolated is a fractional Brownian motion surface with additive measurement error. There are several advantages to this method: data sets with different mean-squared measurement errors can be optimally merged, and the variance of the estimator can be easily computed at each interpolation point. An iterative algorithm is given for implementing the estimator with...

The end of the Cold War and its impact on defense spending has created a strong need to reform the Department of Defense's (DoD) acquisition system. With procurement spending down, DoD expects to depend on savings from acquisition reform to help finance future force modernization. Policy makers believe that DoD should use more commercial products because, in many instances, they cost less and their quality is comparable to products built according to DoD military specifications. Many such...

As the Air Force faces end strength reductions and force structure changes, it becomes more difficult to support the AEF construct using current force employment practices. To meet congressionally mandated end strength ceilings, the Air Force must eliminate approximately 40,000 active duty personnel in the next several years, without sacrificing operational capabilities. If the Air Force desires to keep pilot production at or near 1,000 pilots per year, alternative organizational structures and...

In contrast, when security forces failed to act decisively, the fragile...

We have demonstrated that the unique susceptibility of the ACI rat to E2-induced mammary cancers is inherited in ACI x Copenhagen (COP) and ACI x Brown Norway (BN) genetic...

Such traffic-induced damage can be minimized by a variety of design methods; however, most are not economically feasible. As a result, loads are often restricted or prohibited during thaw-weakened periods. While this practice reduces road maintenance costs, the economic impact on industries that rely on continued heavy trucking can be significant. This report reviews...
