Ultrasonic flowmeters that use transit-time ultrasonic transducers face measurement errors due to “crosstalk,” whereby the working signal travels through pipe wall and couplings, interfering with from fluid. Although various procedures have been proposed solve issue of crosstalk, they’re limited low-frequency ranges, or they are not effective in high-pressure environments. We propose a mounting...

Technology based on additive manufacturing is rapidly emerging and being used in a wide range of industries. Meeting the precision accuracy (P&A) requirements 3D printed parts (shape size tolerances, surface quality, etc.) increasingly becoming an issue. This paper presents critical analysis tribological problems encountered printing for manufactured through different types technologies, su...

Phononic crystals have attracted wide attention in diverse scientific communities due to their ability efficiently reflect, focus, and guide acoustic elastic waves. Their use ultrasonic applications such as medical imaging, however, remains elusive since three-dimensional phononic with lattice constants the range of hundreds micrometers are required operate MHz ultrasound, smaller than what mos...

In manufacturing lithium-ion battery packs for electrical vehicles such as the Chevy Volt, it is critical to create reliable interconnections between battery cells, module-to-module, and module-to-control unit. Such joint connections must possess reliable electrical conductivity and sufficient mechanical strength to ensure battery performance. Ultrasonic metal welding has been adopted for batte...

To amount to a new industrial revolution, the technological changes brought by additive manufacturing must go side by side with new operations management practices. What will these practices be, that fully reap the gains from additive manufacturing? The case study of a firm adopting this technology offers some preliminary answers.

Additive manufacturing technology using inkjet offers several improvements to electronics manufacturing compared to current nonadditive masking technologies. Manufacturing processes can be made more efficient, straightforward and flexible compared to subtractive masking processes, several time-consuming and expensive steps can be omitted. Due to the additive process, material loss is minimal, b...

Abstract Co-Cr alloys are frequently used for highly stressed components, especially in turbine and plant construction, due to their high resistance thermal mechanical stress, as well corrosive abrasive loads. Furthermore, they classified difficult-to-cut materials because of strength toughness low conductivity. However, Co, an increased cost supply risk can be observed recent years. Therefore,...
