AbstractHigh-resolution (λ/δλ ⋍ 6 x 104) spectra of R136 (the central object of 30 Dor) and of 2 LMC supergiants obtained at ESO with the 1.4-m telescope have been analysed in order to study the high-velocity absorption components at VLSR ⋍ +60 km s-1 and ⋍ +130 km s-1 first seen in satellite ultraviolet spectra in the general direction of the LMC. Our data have been integrated with previous literature results of SN1987a and of other 4 LMC supergiants obtained from spectra of similar spectral resolution.At least 6 (possibly 9) interstellar components are found in the range +40 km s-1 ≤ VISR ≤

The present research activity aims at studying different conditions for the circumferential friction stir welding of cylindrical components in aluminium alloy. Different parameters have been considered, such as the rotational velocity of the tool, the tangential velocity of the cylindrical elements and the number of welding passes. The obtained data have been analysed and the strength of each joint modelled. It has been observed a relevant effect of the combination between the rotational velocity of the tool and the tangential velocity of the cylindrical components on the strength of the joint

Abstract:

We perform seismic diffraction imaging and time-migration velocity analysis by separating diffractions from specular reflections and decomposing them into slope components. We image the slope components using migration velocity extrapolation in time-space-slope coordinates. The extrapolation is described by a convection-type partial differential equation and implemented in a highly parallel manner in the Fourier domain. Synthetic and field data experiments show that the proposed algorithms are able to detect accurate time-migration velocities by measuring the flatness of diffraction events in

This study investigates the effect of air velocity and other thermal components on the globe thermometer response. An experiment was conducted in an environmental chamber in order to measure globe temperatures under varying air velocity, relative humidity and air temperature. This study was performed under three different radiant heat levels. It was found that air velocity has a significant effect on the globe thermometer response. This effect is quantified in this study. Neither air temperature nor relative humidity was found to have a significant effect on globe thermometer response.

Abstract:

AbstractV505 Mon is an early type eclipsing binary (usually classified as B5 Ib), in which only spectral lines of the primary component are visible. The radial velocity curve provides f(m) = 4.6 M⊙, suggesting that the secondary, invisible component is more massive. We have found evidence that this star is hidden from view by the disk detected during the primary eclipse. The structure of the disk can be characterized by a central ionization zone surrounded by the neutral outer parts. The profiles of the CII 1335/6 doublet lines were used to derive the rotational velocity of the disk as well as

A new model of the projectile motion for the resistance being proportional to the square of velocity components is investigated. In the course of the projectile motion, the direction of the resistance and the direction of the velocity are not entirely the opposite and on a straight line, in which the deviation angle exists. The size and the interrelation of velocity components determinate the size of the deviation angle, where deviation angles of some points take zeroes and another points take maximum values.

Reverse time migration backscattering contains kinematic information that can be used to constrain velocity models. The backscattering results from the correlation between forward scattered and backscattered wavefields from sharp interfaces, i.e., sediment-salt interfaces. The synchronization between these wavefields depends on the velocity of the sediment section and the correct interpretation of the sharp boundary. We have developed an optimization workflow in which the sediment velocity and the sharp boundary are updated iteratively. The presence of sharp boundaries in the model lead to hig

Bidirectional relativistic proper motions of radio components of nearby extragalactic sources give a strong constraint on the determination of the Hubble constant H0. Under the assumption that the real velocity of radio components of extragalactic sources is not less than that of Galactic sources, the value of H0 can be estimated at a high level of accuracy. The assumption is reasonable due to the general belief that the activity in the core of galaxies must be more powerful than that of stars.

Abstract:

Clattering motion that occurs when flat objects strike the ground at an oblique angle is studied through a simple, tractable, model of a rigid bar with arbitrary, but symmetric, mass distribution and coefficient of restitution. The maximum velocity changes, or velocity shocks, that occur at various locations of the bar as it clatters to rest, are presented. It is shown that different parts of the bar can be subjected to sequences of velocity changes that are both higher, and lower, than those encountered in a single clatter-free impact. The implication that the drop-tolerance of an electronic

Abstract:

Terrestrial navigation naturally involves translations within the horizontal plane and eye rotations about a vertical (yaw) axis to track and fixate targets of interest. Neurons in the macaque ventral intraparietal (VIP) area are known to represent heading (the direction of self-translation) from optic flow in a manner that is tolerant to rotational visual cues generated during pursuit eye movements. Previous studies have also reported that eye rotations modulate the response gain of heading tuning curves in VIP neurons. We tested the hypothesis that VIP neurons simultaneously represent both h

Abstract:

Instantaneous measurements of water velocity at depth in the nearshore are rich with information about orbital velocities, longshore and cross shore currents, and forces that lead to sediment transport. Yet measurements of detailed subsurface velocities are scarce owing to the difficulties involved in installing and maintaining instruments such as acoustic velocimeters in high energy environments like the surf zone [Thornton and Guza, 1986]. Deploying in-situ instruments to measure velocity profiles often involves heavy machinery (e.g. cranes, waterjets, tripods, boats) and after deployment th

Abstract:

Abstract Circumstellar OH maser lines are useful for studying the dynamics of the circumstellar envelope (CSE) around evolved stars. This study aims to identify CSEs around cold stars, which exhibit deviations from the spherical expansion, by comparing the velocity ranges of the OH main lines (1665/1667 MHz) with those of the satellite line (1612 MHz), using a database of circumstellar OH maser sources. We performed this comparison for 377 circumstellar OH maser sources. In addition, using infrared two-color diagrams, we examined the evolutionary stages and infrared properties of objects showi

Abstract:

The torque-velocity relationship has been widely considered as reflecting the mechanical properties of the contractile apparatus, and the influence of tendinous tissues on this relationship obtained during in vivo experiments remains to be determined. This study describes the pattern of shortening of various muscle-tendon unit elements of the triceps surae at different constant angular velocities and quantifies the contributions of fascicles, tendon, and aponeurosis to the global muscle-tendon unit shortening. Ten subjects performed isokinetic plantar flexions at different preset angular veloc

Abstract:

The purpose of the research was to consider solid particles moving in part-flow hydrodynamic filters with a rotating perforated baffle and simulate liquid flows in the working zones of filters. The paper introduces the results of the study. Within the research, we determined the averaged values of the tangential, radial and axial components of the movement velocitis depending on the radius of the device, confirmed the validity of using a cylindrical filter wall, and established the presence of low-pressure and pressure modes of liquid cleaning in the filters. We revealed that in the low-pressu
