Deformation behavior and microstructure evolution of NiTiCu shape memory alloy (SMA), which possesses martensite phase at room temperature, were investigated based on a uniaxial compression test at the temperatures of 700~1000 ◦C and at the strain rates of 0.0005~0.5 s−1. The constitutive equation of NiTiCu SMA was established in order to describe the flow characteristic of NiTiCu SMA, which is...

In contrast to conventional (trans)action concepts the proposed dynamic action model includes the possibility for optimistic recovery in order to gain high efficiency during normal operation. To minimize time overhead we use a redundant recovery graph to record the necessary recovery information. Based on this graph we provide decentral ized protocols that efficiently produce a consistent syste...

BACKGROUND AND OBJECTIVE Dynamic balance involving movement of the centre of gravity is important for the evaluation of street fitness after sedation. The purpose of this study was to compare the recovery of dynamic balance after intravenous sedation with propofol or midazolam, and to investigate the usefulness of simple dynamic balance tests in evaluating the recovery. METHODS Fourteen young...

Objective: To provide a principled, theoretical basis to improve interface tools for helping users recover from task interruptions and get back up to speed in dynamic operational tasks. Background: Multi-tasking and interruptions that disrupt situation awareness are common to many dynamic operational tasks, from monitoring airspaces and plant operations to conducting tactical missions, civil em...

Recent advances in imaging sensors and digital light projection technology have facilitated a rapid progress in 3D optical sensing, enabling 3D surfaces of complex-shaped objects to be captured with improved resolution and accuracy. However, due to the large number of projection patterns required for phase recovery and disambiguation, the maximum fame rates of current 3D shape measurement techn...

In this paper we investigate how shared memory clusters can take advantage of replication to tolerate single system failures. We start from a shared virtual memory protocol (GeNIMA) that has been optimized for low-latency, highbandwidth system area networks. We propose a set of extensions that maintain shared data consistent in the presence of failures and support SMP nodes. Our scheme uses dyn...
