The purpose of this paper is to evaluate the dosimetric capabilities and the radiation protection (RP) performance of a new automatic needle-loading system for permanent prostate implants, the Isoloader (Mentor Corp.). The unit has been used in more than 100 clinical cases at our institution. The Isoloader is a computerized workstation that allows automated seed testing by a solid-state CdZnTe ...

Power head is the main motive mechanism of rotary drilling rig. High axial pressure and high frequency is one of its typical working conditions. Axial loading test is a key point in power head performance tests. Overall design, system theoretical analysis and simulation of power head axial loading system were carried out. The bond graph model and state equations of power head axial servo loadin...

This paper presents an Integrated Management System of DistributionTransformer Loading using a relational database and loss of life estimation through artificial neural networks. This fully integrated software solution allows for technical personnel to carry out studies of transformers data, such as load curves and loss of life. It permits the analysis of these results by location and substitut...
