Blocking: Reduction of detector signal rate when aligned with a crystal axis or plane. Channeling: Guided trajectory of incident ions between crystal axes or planes. Collision cascade: Series of atom-atom collisions initiated by an ion-atom collision. Cross section: Effective area presented by each atom or nucleus for a specific type of interaction with an incoming ion. lmplantation: Addition o...

The lobula giant movement detector (LGMD) and descending contralateral movement detector (DCMD) constitute one motion-sensitive pathway in the locust visual system that is implicated in collision-avoidance behaviors. While this pathway is thought to respond preferentially to objects approaching on a direct collision course, emerging studies suggest the firing rate is able to monitor more compli...

To find the status of multiple collisions in transitional granular flow, moderate to densely packed monosized plastic disks were sheared in experimental 2D shear flow apparatus by applying shear strain rate in the range of 14.8 s−1 to 34.6 s−1. Application of high speed video camera and subsequent image processing techniques precisely measure the spatial positions of the particles involved in m...

In recent years, many studies have been made in the biomechanical and other fields on, “whiplash” or cervical vertical sprain which is on type of injury sustained by vehicle occupants in low-speed rear-end collisions. This paper describes a cervical analysis of whiplash occurring in the lower rear-end collision. In particular, it describes the use of a more humanized biomechanical cervical mode...

We present the formulation of a conservative spectral scheme for Boltzmann collision operators with anisotropic scattering mechanisms to model grazing collision limit regimes approximating the solution to the Landau equation in space homogeneous setting. The scheme is based on the conservative spectral method of Gamba and Tharkabhushanam [17, 18]. This formulation is derived from the weak form ...

Binary Exponential Backoff (BEB) is the De-facto mechanism for contention control in IEEE 802.11 Wireless LAN. The exponential growth of Contention Window (CW) in all BackOff (BO) stages and randomness in BO selection causes unnecessary waiting time, high collision rate and unfairness in accessing the channel among the nodes. To overcome these anomalies, this paper proposes Hashing Based Distri...

A moving vehicle may very likely run into accidents. The occurrence rate of accidents would be largely reduced if the driver were warned in advance, even only 0.5 s earlier. For a running vehicle, the driving route within short time before collision has the character of Markov. In this case, we only have to consider the coordinates of position within a short range, rather than the running statu...

The features of transmissions in underwater sensor networks (UWSNs) include lower transmission rate, longer delay time, and higher power consumption when compared with terrestrial radio transmissions. The negative effects of transmission collisions deteriorate in such environments. Existing UWSN routing protocols do not consider the transmission collision probability differences resulting from ...

While this pathway is thought to respond preferentially to 20 objects approaching on a direct collision course, emerging studies suggest the firing rate is able 21 to mon...
