We investigate the existence of Taub-NUT/bolt solutions in Gauss-Bonnet gravity and obtain the general form of these solutions in d dimensions. We find that for all nonextremal NUT solutions of Einstein gravity having no curvature singularity at r = N , there exist NUT solutions in Gauss-Bonnet gravity that contain these solutions in the limit that the Gauss-Bonnet parameter α goes to zero. Fur...

In this study, we developed a highly reliable CAE analysis model of the mechanisms that cause loosening of bolt fasteners, which has been a bottleneck in automobile development and design, using a technical element model for highly accurate CAE that we had previously developed, and verified its validity. Specifically, drawing on knowledge gained from our clarification of the mechanisms that cau...

Fatigue crack growth during the service life of aging aircraft is a critical issue and monitoring of such cracks in structural hotspots is the goal of this research. This paper presents a procedure for classification and detection of cracks generated in bolted joints which are used at numerous locations in aircraft structures. Single lap bolted joints were equipped with surface mounted piezoele...

A nuclear analysis was performed for an alternate ITER first wall attachment scheme to estimate the nuclear heating in critical components. With a variety of components near the first wall without direct cooling, there is concern that the operating temperatures will be above engineering limits. Using DAG-MCNP5, a 1-D analysis framework was used to estimate the nuclear heating in a detailed 3-D ...

Interest in the analysis of DNA from ancient bone material (3) has increased greatly since it was first demonstrated with the amplification of mitochondrial DNA sequences from 5500-year-old human remains (1). Although the methods involved are not technically demanding, they have remained the preserve of specialist laboratories, primarily because of problems associated with the avoidance of cont...

A homicide with a captive bolt pistol (slaughterer's gun) is reported. The construction and the function of this "humane killer" as well as the typical patterns of injury are described.

4 A drawing of a graph is pseudolinear if there is a pseudoline arrangement such that 5 each pseudoline contains exactly one edge of the drawing. The pseudolinear crossing 6 number c̃r(G) of a graph G is the minimum number of pairwise crossings of edges in 7 a pseudolinear drawing of G. We establish several facts on the pseudolinear crossing 8 number, including its computational complexity and i...

We describ e a system that integrates real time com puter vision with a sensorless gripper to provide closed loop feedback control for grasping and manipulation tasks Many hand eye coordination skills can be thought of as sensory control loops where specialized reasoning has been embodied as a feedback or control path in the loop s construction Our framework cap tures the essence of these hand ...

OBJECTIVE To analyze the in vitro mechanical strength of the DHS-AF(®). METHODS We evaluated the in vitro resistance of a sliding bolt modified by the addition of a connector system, DHS-AF(®). RESULTS The changes performed by the authors allow the exchange by the surgeon of the sliding bolt without the need to remove the plate and disassemble the entire device to reposition it properly. We...
