Kinesthetic control simulator

A kinesthetic control simulator is reported that has a flat base upon which rests a support structure having a lower spherical surface for rotation on the base plate with columns which support a platform above the support structure at a desired location with respect to the center of curvature of the spherical surface. A handrail is at approximately the elevation of the hips of the operator above the platform with a ring attached to the support structure which may be used to limit the angle of tilt. Five degree freedom-of-motion can be obtained by utilizing an air pad structure for support of the control simulator

Some Aspects of Late Prehistoric and Protohistoric Archaeology in Southern Texas

This paper is concerned with the last several hundred years of the prehistoric period in the southern part of Texas. The earlier human occupation of this region, extending back perhaps 11,000 years, has been summarized elsewhere (Hester 197la). The Paleo-Indian period is represented by scattered surface finds of Clovis and Fol6om projectile points, and by a variety of Late Paleo-Indian point styles, such as Plainview, Scottsbluff, Golondrina, Angostura and Merserve.. The following Archaic era is poorly defined, although there are numerous surf ace sites and an abundance of chipped stone artifacts (cf. Weir 1956; Hester, White and White 1969)

Lewis icing research tunnel test of the aerodynamic effects of aircraft ground deicing/anti-icing fluids

A wind tunnel investigation of the effect of aircraft ground deicing/anti-icing fluids on the aerodynamic characteristics of a Boeing 737-200ADV airplane was conducted. The test was carried out in the NASA Lewis Icing Research Tunnel. Fluids tested include a Newtonian deicing fluid, three non-Newtonian anti-icing fluids commercially available during or before 1988, and eight new experimental non-Newtonian fluids developed by four fluid manufacturers. The results show that fluids remain on the wind after liftoff and cause a measurable lift loss and drag increase. These effects are dependent on the high-lift configuration and on the temperature. For a configuration with a high-lift leading-edge device, the fluid effect is largest at the maximum lift condition. The fluid aerodynamic effects are related to the magnitude of the fluid surface roughness, particularly in the first 30 percent chord. The experimental fluids show a significant reduction in aerodynamic effects

Numerical simulations of riveted connections under quasi-static and dynamic loadings

Despite years of concerted effort in the war against terrorism, there still exist terrorist networks and lone wolf actors that continue to threaten people and infrastructure around the world. Among the potential targets of terrorists are the more prominent, high value, and symbolic locations that make up the United States’ critical transportation network. This is an urgent national security issue. While many organizations such as the Federal Highway Administration (FHWA) and the Association of State Highway and Transportation Officials (AASHTO) continue to sponsor experts from professional practice, academia, and other agencies to develop strategies to deter and disrupt such attacks, there is little known about the specific response of riveted connections under high rates of loading. A general lack of access and expertise with riveted connections, which have not been widely used in construction of bridges since the 1950s, and the expense and difficulty in replicating and collecting accurate data for close-in detonation testing on riveted steel connections make it a challenge to analyze and estimate the capacity and behavior of riveted connections. This research focuses on numerical simulation of riveted steel connections under high rates of loading. Finite element modeling using LS-DYNA (2013) is first developed to match the physical testing of A502 Grade 2 riveted structural connections subjected to dynamic and quasi-static shear loadings completed at the U.S. Army Engineer Research and Development Center (ERDC). This initial modeling serves as validation for the LS-DYNA (2013) model parameters for response. Subsequent analyses expand on the validated modeling to serve as a numerical prediction of additional riveted connections subjected to dynamic loads. Results from the testing and numerical simulations can serve to expand the capabilities of existing anti-terrorist planning software and serve as an addition to existing bridge protection guidelines. The numerical simulation modeling will fill an important gap in the current knowledge base on the performance of riveted connections under high loading rates that will be of value to the U.S. Army Corps of Engineers and the Federal Highway Administration. Understanding the capacity and behavior of these connections will assist future researchers in developing mitigation strategies against blast loadings.Civil, Architectural, and Environmental Engineerin

Significant evidence for a heritable contribution to cancer predisposition: a review of cancer familiality by site

<p>Abstract</p> <p>Background/Aims</p> <p>Sound and rigorous well-established, and newly extended, methods for genetic epidemiological analysis were used to analyze population evidence for genetic contributions to risk for numerous common cancer sites in Utah. The Utah Population Database (UPDB) has provided important illumination of the familial contribution to cancer risk by cancer site.</p> <p>Methods</p> <p>With over 15 years of new cancer data since the previous comprehensive familial cancer analysis, we tested for excess familial clustering using an expanded Genealogical Index of Familiality (dGIF) methodology that provides for a more informative, but conservative test for the existence of a genetic contribution to familial relatedness in cancer.</p> <p>Results</p> <p>Some new cancer sites have been analyzed for the first time, having achieved sufficiently large sample size with additions to the UPDB. This new analysis has identified 6 cancer sites with significant evidence for a heritable contribution to risk, including lip, chronic lymphocytic leukemia, thyroid, lung, prostate, and melanoma.</p> <p>Conclusions</p> <p>Both environmentally and genetically-based familial clustering have clinical significance, and these results support increased surveillance for cancer of the same sites among close relatives of affected individuals for many more cancers than are typically considered.</p
