This paper studies the defect detection problem of adhesive layer of thermal insulation materials. A novel detection method based on an improved particle swarm optimization (PSO) algorithm of Electrical Capacitance Tomography (ECT) is presented. Firstly, a least squares support vector machine is applied for data processing of measured capacitance values.(More)
For characterizing the series augmented railgun launching process, the study from analysis of muzzle voltage was insufficient since armature velocity, resistance and voltage drop of armature were also important to the launching process. In the present work, the variations of armature velocity, total resistance and voltage drop of armature against time were(More)
In the paper, the simulation and the experiment were carried on a kind of planar series augmented electromagnetic rail launcher. Different from other researches on electromagnetic launcher's analysis, many practical effects were fully considered in launching process such as friction force, air resistance, heat generation and so on. Launching process and(More)
