background: the control of spread of hiv takes concerted efforts at both national and international levels. education is an important component of preventing the spread of hiv. this study aimed to assess the attitudes of parents, teachers and students towards informing children about hiv/aids, attitudes concerning 'proper' age to learn about hiv/aids, possible differences in attitudes relating ...

Reversible logic has attracted tremendous interest among the researchers in low power VLSI field due to their simple structure and improved energy efficiency. In this paper, the implementation of an 8-bit low power multiplier based on reversible gate technology is reported. The structure of the reversible gate multiplier consists of following components: the first part is the reversible partial...

We show that the assumption n1 > λ in the Second Multiplier Theorem can be replaced by a divisibility condition weaker than the condition in McFarland’s multiplier theorem, thus obtaining significant progress towards the multiplier conjecture.

Article history: Received Accepted Available online 20 Nov. 2014 19 Dec. 2014 25 Dec. 2014 Based on the simplification of the addition operations in a low-power bypassing-based multiplier, a low-cost low-power bypassing-based multiplier is proposed. Row-bypassing multiplier, column-bypassing multiplier, 2-Dimensional bypassing multiplier and braun multipliers are implemented in CMOS and GDI tec...

This paper proposes a novel recursive structure block-based Wallace tree multiplier with the capability to tune its accuracy based on the precision and power requirements. The multiplier performs multiplication operations recursively from small blocks to large blocks, with a fine grain capability of turning off small blocks to trade off with power. By tuning the fidelity design “knob”, we show ...

The newly proposed reconfigurable multiplier blocks offer significant savings in area over the traditional multiplier blocks for time-multiplexed digital filters or any other system where only a subset of the coefficients that can be produced by the multiplier block is needed in a given time. The basic structure comprises a multiplexer connected to at least one input of an adderhbtractor that c...

Multiplication is one of the basic functions used in digital signal processing (DSP). It requires more hardware resources and processing time than addition and subtraction. In fact, 8.72% of all instructions in a typical processing unit is multiplier. The multiplier is a fairly large block of a computing system. The amount of circuitry involved is directly proportional to square of its resoluti...

ABSTRACT This paper introduces a digit-serial GF(2m) multiplier for use in the polynomial basis. The multiplier works with the most significant digit first and is scalable to an arbitrary digit size and can be constructed for any GF(2m). It is derived from a commonly used MSB first bit-serial multiplier, known as the standard shift-register multiplier. As the latency of the multiplier decreases...

The Multiplier Hopf Group Coalgebra was introduced by Hegazi in 2002 [7] as a generalization of Hope group caolgebra, introduced by Turaev in 2000 [5], in the non-unital case. We prove that the concepts introduced by A.Van Daele in constructing multiplier Hopf algebra [3] can be adapted to serve again in our construction. A multiplier Hopf group coalgebra is a family of algebras A = {A α } α∈π ...
