The journey of production tools in cold working, hot and injection molding from rapid tooling to additive manufacturing (AM) by laser-based powder bed fusion (L-PBF) is described. current machines their configurations, tool steel materials properties, the L-PBF process parameters for these are specified. Examples designed made Efficient design, i.e., high efficiency performance operation, shoul...

Palimpsest is a novel purely-visual language intended to support exploratory live programming. It demonstrates a new paradigm for the visual representation of constraint programming that may be appropriate to future generations of keyboardless and touchscreen devices. The current application domain is that of creative image manipulation, although the paradigm can support a wider range of comput...

This paper proposes 7T SRAM which realizes block-level simultaneous copying feature. The proposed SRAM can be used for data transfer between local memories such as checkpoint data storage and transactional memory. The 1-Mb SRAM is comprised of 32-kb blocks, in which 16-kb data can be copied in 33.3 ns at 1.2 V. The proposed scheme reduces energy consumption in copying by 92.7% compared to the c...

In this paper, we describe the need for intelligent retrieval components in materials information systems. Starting from an object-oriented tool-based retrieval interface, three modules for intelligent query support are presented: WING-GRAPH, a facility allowing for direct manipulation based graphical retrieval exploiting the cognitive abilities involved in graphical thinking and interpretation...

Combustion noise can be classified as direct or indirect, the former related to the flame’s unsteady heat release, and the latter to the acceleration/deceleration of convected flow disturbances. An analytical and numerical analysis of the direct and indirect noise produced by the generation and acceleration of entropy waves in a reflective environment is presented. A model for the direct noise ...

This paper reviews the direct bonding technique focusing on the waveguide optical isolator application. A surface activated direct bonding technique is a powerful tool to realize a tight contact between dissimilar materials. This technique has the potential advantage that dissimilar materials are bonded at low temperature, which enables one to avoid the issue associated with the difference in t...

A simple proof of Tychonoff’s theorem (the compactness of the product of compact spaces) as a direct application of Zorn’s lemma is given. In contrast to the classical Cartan-Bourbaki proof which uses Zorn’s lemma twice, our proof uses it only once.
