A low-speed counter-rotating axial flow compressor (CRAC) with single circumferential grooved casing treatment (CT) was investigated numerically. Both steady and time-accurate numerical calculations were performed to study the effects of the single grooved CTs over the rear rotor on the stability enhancement and the unsteadiness of tip leakage flow (TLF) in the CRAC. Parametric studies indicate...

Four experiments explored the hypothesis that temporal processes may be represented and controlled explicitly or implicitly. Tasks hypothesized to require explicit timing were duration discrimination, tapping, and intermittent circle drawing. In contrast, it was hypothesized that timing control during continuous circle drawing does not rely on an explicit temporal representation; rather, tempor...

Assume two parties, Alice and Bob, want to compute a joint function, but they want to keep their inputs private. This problem setting and its solutions are known as secure computation. General solutions to secure computation require the construction of a binary circuit for the function to be computed. This paper proposes the concept of languagebased secure computation. Instead of constructing a...

Background: Advances in neonatal intensive care have markedly improved survival in preterm infants. These babies need hospitalization due to the immaturity of the respiratory and digestive systems. The timing for the initiation of proper feeding in premature infants admitted to neonatal intensive care units (NICUs) is an important challenge for physicians, parents, and...

SPARK 2014 is a safety critical language subset of Ada developed by Altran and used for developing safe and secure software by major industrial players in the aviation, commercial, medical, space, and military domains. This paper puts a spotlight on the SPARK flow analysis. Articulating the boundaries of what is achievable by the analysis, we spell out attacks to exploit termination, progress, ...

The paper presents a systemic approach of a walking robot behavior and control in uncertain environments, with application to a hexapod robot. For simplicity, this paper considers only the vertical xz-plane evolution taking into account that the structure is symmetrical in the horizontal xy-plane and the results can be easily extended. Based on the mathematical model of the robot, determined co...

Sample-timing error can cause significant performance degradation for the interleave-division multiple-access systems (Wang et al. 2009). In this paper, we propose a nondata-aided timing acquisition scheme tomitigate sample-timing error due to the asynchronous transmission of random allocated user ends (UEs) on the uplink. A closed-loop timing control scheme is constructed for the asynchronous ...

This study investigates the effect of synchronized metronome training (SMT) on motor timing and how this training might affect golf shot accuracy. Twenty-six experienced male golfers participated (mean age 27 years; mean golf handicap 12.6) in this study. Pre- and post-test investigations of golf shots made by three different clubs were conducted by use of a golf simulator. The golfers were ran...
