In this paper, the flocking problem in a network of double-integrator agents with limited angular fields of view (FOV) is investigated. The angular FOV represents the limitation imposed on the velocity sensor mounted on every agent in the network, while the position sensors are assumed to be omnidirectional. To increase the sensing capabilities of agents and preserve network connectivity, it is...

Albert and Miller (1997) performed an analysis of vertical velocity and angular momentum for single and double Axels. Their results indicate that both radial and tangential motion of the skater are critical to the generation of vertical velocity throughout the take-off of single and double Axels. In generating angular momentum during the take-off, the movement of the free leg was most critical....

In order to decrease the velocity sculling error under vibration environments, a new sculling error compensation algorithm for strapdown inertial navigation system (SINS) using angular rate and specific force measurements as inputs is proposed in this paper. First, the sculling error formula in incremental velocity update is analytically derived in terms of the angular rate and specific force. ...

Abstract Recently, orbital angular momentum (OAM) has been adopted to measure the shape of static objects and translation motion moving in optical remote sensing. Most these studies rely on measuring intensity variation OAM beams. However, does not change with rotation spinning object, but its phase changes. The is proved be proportional object’s velocity. Since a rotating object will cause dep...

the present study deals with the analysis of the effects of radiative heat transfer of micropolar fluid flow over a porous and stretching sheet in the presence of magnetic field. the dynamic viscosity and thermal conductivity coefficient have formulated by temperature-dependent relations to obtain more exact results. the flow is supposed two-dimensional, incompressible, steady and laminar and t...

The existence of outflow in the advection dominated accretion flows has been confirmed by both numerical simulations and observations. The outow models for ADAF have been investigated by several groups with a simple self similar solution. But this solution is inaccurate at the inner regions and can not explain the emitted spectrum of the flow; so, it is necessary to obtain a global solution for...

The purpose of present study was to examine the effects of short time static and dynamic stretching of muscles on kinematics variability of lower extremity in healthy active males during cycling. 15 physical education and sport sciences male students from Kharazmi University voluntarily participated in this study. Subjects referred to the laboratory during two days, with 48 hours intervals betw...

PURPOSE The aim of this study was to determine differences in bat swing kinematics in baseball hitters of varying ability. METHODS Kinematic data for the upper and lower body were collected from 20 trained male baseball players (22.3 ± 5.3 yr, 1.82 ± 0.07 m, 83.5 ± 10.9 kg), using three-dimensional computerized motion-analysis techniques. Participants were ranked before testing based on a nov...
