ANALYSIS OF SPOT-WELDING PITCH ON TOP HAT STRUCTURE AGAINST CRASHWORTHINESS CRITERIA

FDTD Analysis of Top-Hat Monopole Antennas Loaded with Radially Layered Dielectric

Top-hat monopole antennas loaded with radially layered dielectric are analyzed using the finite-difference time-domain (FDTD) method. Unlike the mode-matching method (MMM) (which was previously used for analyzing these antennas) the FDTD method enables us to study such structures accurately and easily. Using this method, results can be obtained in a wide frequency band by performing only one ti...

Morphological connected contrast mappings based on top-hat criteria: A multiscale contrast approach

Iván R. Terol-Villalobos Centro de Investigación y Desarrollo Tecnológico en Electroquı́mica Parque Tecnológico Querétaro Sanfandila-Pedro Escobedo 76700-APDO 064, Querétaro México E-mail: [email protected] Abstract. We present a multiscale image approach for contrast enhancement based on a composition of contrast operators. Contrast operators are built by means of the opening and closing by ...

Design of Spot Welding Robot

Welding robot has played an extremely important role in the welding production of high-quality, high-efficiency. The paper designed the hardware structure and software of spot welding robot. The hardware design mainly includes the major modules of arm and base; the hardware design includes two parts: manual mode and automatic mode. Manual mode is generally used for the robot system installation...
