The problem of the determination of the rotation harmonics 03A61, 03A62, ... for the case of a numerical diatomic potential is considered. These harmonics defined in a recent work by 03C8vJ = 03C8v0 + 03BB03A61 + 03BB2 03A62 + ··· (where 03C8vJ is the wave function of the vibration level v and the rotation level J, and 03BB = J(J + 1)) are studied for the case of the Dunham potential and for a ...

A previous infrared multiple photon dissociation (IRMPD) action spectroscopy and density functional theory (DFT) study explored the structures of the [M,C,2H]+ products formed by dehydrogenation of methane by four, gas-phase 5d transition metal cations (M+ = Ta+, W+, Ir+, and Pt+). Complicating the analysis of these spectra for Ir and Pt was observation of an extra band in both spectra, not rea...

Three patients with a right hemisphere lesion and marked left-sided neglect without visual field defects were asked to detect and identify stimuli which were tachistoscopically presented in the left or right visual half-field. Neglect of stimuli presented in the contralesional left visual field, which was observed when the patient's body was in a normal upright position with trunk, head and gaz...

A hybrid-hybrid (ultrasonic-assisted + laser-assisted) turning study of silicon carbide reinforced aluminium metal matrix composite is presented. The results show a significant reduction average cutting force with an improved surface finish machined components compared to conventional machining, implying that this new and novel paradigm viable machining process.

The ability to recognize the encountered terrain is an essential part of any terrain-dependent control system designed for mobile robots. Terrains such as sand and gravel make vehicle mobility more difficult and thus reduce vehicle performance. To alleviate this problem the vehicle control system can be tuned for maximum speeds, turning angles, accelerations and other conditions to help adapt t...

This paper introduces an online prototype system including two independent modules of chatter stability prediction and monitoring for industrial applications. Turning processes are considered. At first, the stability charts are analysed by the Laplace transform. The charts obtained can assist the operators in selecting appropriate machining parameters before operations. Secondly, the characteri...

ABSTRACT. S-transformation is proposed to evaluate the quality of completed turning operations. The calculated time-frequency-amplitude plot of an accelerometer or cutting force signal indicates the vibration level at different frequencies and helps the operator to identify the problems. Time-frequency-damping index plots were obtained by using the s-transformation. Variance of damping index in...
