A Distributed Billiard Ball Simulation

This paper outlines the implementation of a distributed billiard ball simulation in C++ using the MPI message passing interface. The implementation is heavily modelled after the discussions and algorithms found in [Lubachevsky 1991] and [MacKenzie and Tropper 1996]. [Lubachevsky 1991] outlines an efficient but non-distributed simple rigid disc simulator that assumes no friction, spin, et cetera...

Interaction with a crystal ball type display i-ball

The display technologies have made rapid progress. One of the new types of 3D spatial displays is the surround display, by which we can observe small objects from any direction. We proposed and developed a new method for this type of display. Since the developed system is spherical and transparent, it looks like a crystal ball. And we can capture the images of user’s behavior. So, we intend tha...

Small Ball Exercise Program for Patients With Chronic Nonspecific Low Back Pain: A Randomized Clinical Trial

Purpose: Low back pain (LBP) is one of the main causes of disability in adults. Approximately 80% of LBPs lead to chronic nonspecific low back pain (CNSLBP). Damages to back region may be due to weak musculoskeletal structure, impaired muscle or joint flexibility, changes in muscle tone, and reduced strength and endurance. A set of exercises by small ball was designed by the corresponding and f...

L-Ball: Designing A Novel Sports Electronic Audio Ball for Visual Impairment Student

Background. A field study conducted by researchers found the balls used by visual impairment students at school basically used the sound by a small bell inside the ball. However, the sound emitted from the ball is very limited, the ball will sound when it is moved. This makes it difficult for students with visual impairments to find a missing ball that not emitted makes a sound. Objectives. A ...
