GPU-accelerated SART reconstruction using the CUDA programming environment

Magnetorheological fluids consist of micron sized iron particles mixed in a carrier fluid, and are commonly used in adaptive dampers. Current simulations of MR fluids have been limited to thousands of particle and have been unable to simulate a a practical fluid volume (∼ mm3) with a high solids loading (∼ 25 vol %). In this paper, we use NVIDIA’s CUDA programming environment to simulate over one million particles. Using these simulations, we can dynamically simulate chain formation and restructuring in a practical millimeter scale fluid volume with realistic solids loading. The chain structures can be characterized in terms of extent and number, as well as obtaining physical metrics such as yield stress.

The I\O file system Read\Write operations are considered the most significant characteristics. Where, many researchers focus on their works on how to decrease the response time of I\O file system read\write operations. However, most articles concentrate on how to read\write content of the file in parallelism manner. Here in this paper, the author considers the parallelizing Read\Write whole file bytes not only its contents. A case study has been applied in order to make the idea more clear. It talks about two techniques of uploading\downloading files via Web Service. The first one is a traditional way where the files uploaded and downloaded serially. While the second one is uploaded\ downloaded files using Java thread in order to simulate parallelism technique. Java Netbeans 8.0.2 have been used as a programming environment to implement the Download\Upload files through Web Services. Validation results are also presented via using Mat-lab platform as benchmarks. The visualized figures of validation results are clearly clarifying that the second technique shows better response time in comparison to the traditional way.

Pumping Units

It is well known that the bearings of the mechanism of the conventional pumping units are heavily loaded so that their design has to be accomplished very carefully. In this scope the values of the connection forces acting on these bearings has to be determined as accurately as possible. In the paper is presented the kinetostatic analysis of the mechanism of the conventional sucker rod pumping units, obtaining in this way the values of the connection forces in the joints and of the motor moment at the cranks shaft. For processing the experimental records it has been used the program Total Well Management. The simulations have been performed with a computer program developed by the authors using Maple programming environment.
