A 4x4 bit multiplier is demonstrated based on the Chinese abacus. As comparing the simulation result of this work with the speed and power consumption of the 4x4 bits Braun array multiplier, the delays of the 4-bit abacus multiplier are 19.7% and 10.6% less than that of Braun array multiplier with 0.35μm and 0.18μm technologies, respectively. Meanwhile, the power consumption of the 4-bit abacus...

This formalization is an extension to [3]. In their work, the authors have shown that Braun et al.’s static single assignment (SSA) construction algorithm [1] produces minimal SSA form for input programs with a reducible control flow graph (CFG). However Braun et al. also proposed an extension to their algorithm that they claim produces minimal SSA form even for irreducible CFGs. In this formal...

A 4x4 and 8x8 bit multiplier is demonstrated based on the Chinese abacus. As comparing the simulation result of this work with the speed of the 4x4 and 8x8 bits Braun array multiplier, the delays of the 8-bit abacus multiplier are 14% and 7.5% less than that of Braun array multiplier with 0.35μm and 0.18μm technologies, respectively. Meanwhile, the power consumption of the 8-bit abacus multipli...

Abstract—In this paper, a novel Chinese abacus multiplier is presented. The architecture of a 4-bit multiplier is demonstrated. The simulation results of our work are compared with the 4-bit Braun array multiplier. The 0.35μm and 0.18μm TSMC CMOS technologies are used in the simulation. The delay time of the abacus multiplier is at least 63% less than that of Braun array multiplier for 0.18μm t...

This laboratory study to compare the cleaning efficacy of battery-operated power toothbrushes was carried out in two phases. Firstly, the Braun Oral-B D4/EB4 was compared with the Colgate Actibrush and secondly the D4/EB4 was compared with the Dr. Best Powerclean. All three brushes are battery-operated and have a small round brushhead with an oscillating/rotating action. They differ, however, w...

Primarily, the purpose of this document is to note issues for the use of linear and generalized linear models, and of other regression models. Worked examples, as far as possible using data that have been a basis for published research, are used as a basis for discussion of the following issues: Missing variables; noting very striking examples that arise in multi-way tables, perhaps modeled usi...
