We discuss several aspects of direct CP asymmetries in B decays, which are very useful in spite of hadronic uncertainties in asymmetry calculations. 1) Asymmetries in decays to D(∗)K(∗), π+π−, ρ+ρ−, providing precision tests for the CKM phase γ. 2) Null tests in B+ → J/ψK+, π+π0, where a nonzero asymmetry provides evidence for New Physics. 3) Isospin and broken flavor SU(3) relations among CP a...
Power consumption in VLSI systems has become a critical metric for design evaluation. Although power reduction techniques can be applied at every level of design abstraction, most automated power reduction techniques apply to the lower levels of design abstraction, such as the register-transfer or gate level. We therefore investigated the power reduction attainable by the evolving automated beh...
abstract this paper presents a multiobjective power control algorithm that updates the transmitted power based on local information. the proposed algorithm is expanded by using multiobjective optimization schemes. the objectives to be optimized in this paper are determined so as to reduce the sinr fluctuations as well as maintaining the sinr to an acceptable level with minimizing an average tra...
In this paper, the coupled dispersive (2+1)-dimensional long wave equation is studied. The traveling wave hypothesis yields complexiton solutions. Subsequently, the wave equation is studied with power law nonlinearity where the ansatz method is applied to yield solitary wave solutions. The constraint conditions for the existence of solitons naturally fall out of the derivation of the soliton so...
The test scheduling of memory cores can significantly affect the test time and power of system chips. We propose a test scheduling algorithm for BISTed memory cores to minimize the overall testing time under the test power constraint. The proposed algorithm combines several approaches for a near-optimal result, based on the properties of BISTed memory cores. By proper partitioning, an analytic ...
In regular FIR structure, by pipelining the multipliers one can improve the throughput. But as the growth of operand word length, the delay in addition process becomes another important constraint. In this paper, a novel fine-grain pipelining scheme for high throughput FIR is proposed. By pipelining multipliers and adders, very high throughput can be achieved. 2-Dimensional pipeline gating tech...
We consider a distributed joint random access and power control scheme for interference management in wireless ad hoc networks. To derive decentralized solutions that do not require any cooperation among the users, we formulate this problem as non-cooperative joint random access and power control game, in which each user minimizes its average transmission cost with a given rate constraint. Usin...

Mobile channels suffer from multipath fading and necessitate transmitter adaptation to achieve Shannon capacity. The capacity achieving transmitter adaptation strategy depends on how much channel side information (CSI) is available at the transmitter (CSIT) and the receiver (CSIR). When CSI is perfectly known at both sides, it is shown in [10] that for AWGN channels with flat fading, the optima...
