When compared to the over-simplified classical skin-effect model, the accurate classical relaxation-effect modelling approach for THz structures at room temperature can be mathematically cumbersome and not insightful. This paper briefly introduces various interrelated electrical engineering concepts as tools for characterizing the intrinsic frequency dispersive nature of normal metals at room t...

A hollow fiber sampling inlet end of capillary electrophoresis (CE) for small ions in complex samples is described. A short piece of hollow fiber, which only permits small ions to pass through its wall, was directly connected to one end of a capillary. Small ions in complex samples were injected into the capillary through the hollow fiber by an electrokinetic method. The experimental results of...

AbstractTwo test series were carried out on angle cleat connections between cold-formed channels as beams and rectangular hollow sections support members. The objective of the tests was to deter...

In maxillary defects, role of a prosthodontist is to rehabilitate the intra- and extra-oral structures and to endow with the normal function of mastication, speech, deglutition, and esthetics. Malignancies are common in the oral region and are treated usually through surgical intervention. Surgical intervention creates anatomical defects creating communication between oral and nasal cavity. Pat...

This paper presents the excitation of a longitudinal slot on a hollow rectangular coaxial line by a metal support between two conductors and the fabrication by diffusion bonding of laminated metal thin plates. The measured loss of a straight line is 0.046dB/cm at 60GHz while the simulated one is 0.043dB/cm.

The unchangeable need of securing and locating parts during different manufacturing processes turned the fixtures to key elements in many part production industries. The iterations between design engineers and manufacturing planners because of late collision detection of the part/fixtures with robots cost a lot of time and money. The lead-time can be reduced by developing tools and/or methods f...

This paper describes a usefulness measure that supports ongoing work on a hybrid process planning approach that combines the best characteristics of both variant and generative process planning while avoiding their worst limitations. To specify the fixtures needed by a process plan for a new design, the hybrid approach must identify existing designs and process plans that have fixtures that can...
