Teleoperated robots in harsh environments have a significant likelihood of failures. It has been shown in previous work that a common type of failure such as that of a joint “locking up”, when unidentified by the robot controller, can cause considerable performance degradation in the local behavior of the manipulator even for simple point-to-point motion tasks. The effects of a failure become m...

Recurrent event processes with marker measurements are mostly and largely studied with forward time models starting from an initial event. Interestingly, the processes could exhibit important terminal behavior during a time period before occurrence of the failure event. A natural and direct way to study recurrent events prior to a failure event is to align the processes using the failure event ...

background: renal complication of leptospirosis is common and its clinical manifestations vary from urinary sediment changes to acute renal failure. the aim of this study was to determine the final outcome of renal involvement in leptospirosis. methods: this longitudinal prospective study included all serologically confirmed cases of leptospirosis with evidence of renal failure. all patients we...

conclusions: these findings demonstrated that cognitive failure and alexithymia had important roles in strengthening and appearance of high-risk behaviors in students with learning disabilities. therefore, considering those problems, precautionary actions might be necessary. results: the results showed that high-risk behaviors had significant positive correlations with difficulty identifying fe...

We consider the recent British government attempts to reform the House of Lords at Westminster. We show that failures to achieve decisive change are a product of a multi-dimensional ideological space on the issue of institutional reform. In conducting our analysis we note that despite W.O. Adyelotte’s pioneering efforts, roll call voting in the UK parliament remains woefully understudied. We pr...

the present paper investigates the advantages of a new class of composite grid structures over conventional grids. thus far, a known grid structure such as orthogrid or isogrid has been used as an orthotropic layer with at most in-plane anisotropy. the present laminated grid is composed of various numbers of thin composite grid layers. the stiffness of the structure can be adjusted by choosing ...

Existing knowledge about the impact of the experience prior to financial choices has been limited almost exclusively to single risky choices. Moreover, the results obtained in these studies have not been entirely consistent. For example, some studies suggested that the experience of success makes people more willing to take a risk, while other studies led to the opposite conclusions. The result...

We investigate the failure of bacterial floc mediated streamers in a microfluidic device in a creeping flow regime using both experimental observations and analytical modeling. The quantification of streamer deformation and failure behavior is possible due to the use of 200 nm fluorescent polystyrene beads which firmly embed in the extracellular polymeric substance (EPS) and act as tracers. The...

High-strength low alloy steels (HSLA) have been designed to replace high-yield (HY) strength steels in naval applications involving impact loading as the latter, which contain more carbon, require complicated welding processes. The critical role of HSLA-100 steel requires achieving an accurate understanding of its behavior under dynamic loading. Accordingly, in this paper, we experimentally inv...
