Axis Aligned Bounding Box (AABB) is the simple method for object collision detection, but it has limitation in detection process. In decades, some better methods have been generated such as Oriented Bounding Box (OBB) and HPCCD. Unfortunately, these methods are not used in DVE. This paper aims to analyze why most DVEs still use AABB in detecting objects collision in the environment. This resear...

Aiming at the data redundancy problem in process of anti-collision in RFID, an OP(occurrence position) algorithm is proposed in this study, OP algorithm is based on the theory of direct georeference and BS (binary search) algorithm, improve traditional binary search mechanism by changing data transformed by anti-collision commands, data transformed by anti-collision commands in OP algorithm con...

In the thermal spraying process, the process for the molten metal particles to hit against matrix to form coating experiences great change temperature. Since the coating materials has different thermal physical properties with the matrix materials, the residual stress is surely left in the coating. Much bigger residual stress not only restricts coating thickness but also primarily affects coati...

We considered an irreversible biochemical intrachain reaction of supercoiled DNA as a random event that occurs, with certain probability, at the instant of collision between two reactive groups bound to distant DNA sites. Using the Brownian dynamics technique, we modeled this process for a supercoiled DNA molecule of 2.5 kb length in dilute aqueous solution at an NaCl concentration of 0.1 M. We...

OBJECTIVE A common daily-life task is the interaction with moving objects for which prediction of collision events is required. To evaluate the sources of information used in this process, this EEG study required participants to judge whether two moving objects would collide with one another or not. In addition, the effect of a distractor object is evaluated. METHODS The measurements included...

Collision-induced migration (CIM) is a process in which energetic gas-phase atoms or molecules at the tail of the Boltzmann distribution enhance surface migration of adsorbates upon collision. It is believed to exist and play an important role in any realistic high pressure-high-temperature heterogeneous catalytic system. Combining supersonic beam-surface collision setup with in-situ optical se...

A novel droplet mixing measurement technique is presented that employs single fluorophore laser-induced fluorescence, custom image processing, and statistical analysis for monitoring and quantifying mixing in confined, high-speed droplet collisions. The diagnostic procedure captures time-varying fluorescent signals following binary droplet collisions and reconstructs the spatial concentration f...

For the purpose of studying the early process of snowflake growth, characteristics of the Ž . aggregation collision–adhesion process of needle snow crystals were investigated by examining photomicrographs of snowflakes composed of two crystals. The adhesion type of the snowflakes was classified into crossed adhesion and point adhesion types. When the sizes of the two crystals were similar, whic...
