Conditional capture and conditional precharge techniques for high-performance flip-flops are reviewed in terms of power and delay. It is found that application of conditional techniques can improve Energy-Delay Product for up to 14% for 50% input activity and save more than 50% in power consumption for quiet input. This property makes conditional methods suitable for high-performance VLSI systems.

One of the natural ways to prove that the Hall words (Philip Hall, 1933) consist of a basis of a free Lie algebra is a direct construction: to start with a linear space spanned by Hall words, to define the Lie product of Hall words, and then to check that the product yields the Lie identities (Marshall Hall, 1950). Here we suggest another way using the Composition-Diamond lemma for free anti-co...

Anirudha V. Sumant, Orlando Auciello, Robert W. Carpick, Sudarsan Srinivasan, and James E. Butler of smooth diamond films with uniform thickness and micro/nanostructure over large area substrates (≥150 mm diameter wafer), as recently demonstrated.1 Growth of thin (0.1 to 5 micron thick) diamond films on nondiamond substrates, typically conventional electronic substrates such as Si, SiC, and AlN...

Two types of micron-diamond films were prepared on YG6 substrate by hot filament chemical vapor deposition(HFCVD) method. Morphology and orientation of crystalline growth were evaluated by SEM and XRD. Diamond film coated tools and sapphire wafer’ surface before and after lapping experiment  were contrasted. The results indicated that a significant change in Raman spectrum of two types of micro...

Queries that constrain multiple dimensions simultaneously are difficult to express, in both Structured Query Language (SQL) and multidimensional languages. Moreover, they can be inefficient. We introduce the diamond cube operator to facilitate the expression and computation of one such important class of multidimensional query, and we define the resulting cube to be a diamond. The diamond cube ...

In this paper, we establish Composition-Diamond lemma for tensor product k〈X〉⊗k〈Y 〉 of two free algebras over a field. As an application, we construct a GröbnerShirshov basis in k〈X〉 ⊗ k〈Y 〉 by lifting a Gröbner-Shirshov basis in k[X]⊗ k〈Y 〉, where k[X] is a commutative algebra.

The matching preclusion number of a graph is the minimum number of neither edges whose deletion in a graph has a neither perfect matching nor an almost perfect matching. For many interconnection networks, the optimal sets are precisely those induced by a single vertex. Recently the conditional matching preclusion number of a graph was introduced to look for sets beyond those induced by a single...

Recent years witness a growing interest in nonstandard epistemic logics of “knowing whether”, “knowing what”, “knowing how”, and so on. These logics are usually not normal, i.e., the standard axioms and reasoning rules for modal logic may be invalid. In this paper, we show that the conditional “knowing value” logic proposed by Wang and Fan [12] can be viewed as a disguised normal modal logic by...

This paper reviews existing studies and investigates thermal operational regimes of diamond bit during drilling operations. The operating temperature of the diamond core drill is studied under bench condition and an optimal thermal range are presented. Based on this study, it was noted that glazing of diamond tools is observed at temperatures less than 327°C, and normal wear of diamond tools is...
