OBJECTIVE Accurate and reproducible coil positioning is important for headache research using transcranial magnetic stimulation protocols. We aimed to design a transcranial magnetic stimulation coil holder and demonstrate reliability of test-retest coil positioning. METHODS A coil holder was developed and manufactured according to three principles of stability, durability, and three-dimension...

This study summarizes results from a preliminary evaluation of the Hybrid III Large Male Dummy. The paper reviews the dimensions, certification test responses, durability, and repeatability and reproducibility of two Hybrid III 95 Percentile Large Male dummies, each produced by a different manufacturer. Response data from multiple repeats of the proposed Calibration and Inspection Test Procedur...

Tubular structural systems are one of the most common types of systems in high-rise structures. In the early days of this system, there were imperfections in its design which were overcome over time. The most important modification to rectify these defects is the use of a series of internal frames in addition to the peripheral frames and new systems in the center of the plan to eliminate design...
