We study the possibility of generating the observed baryon asymmetry via leptogenesis in the decay of heavy Standard Model singlet fermions which carry lepton number, in a framework without Majorana masses above the electroweak scale. Such scenario does not contain any source of total lepton number violation besides the Standard Model sphalerons, and the baryon asymmetry is generated by the int...

I introduce a new low energy effective description of Cosmological SUSY breaking. It requires the existence of a strongly interacting gauge theory at a scale of order 10 GeV, some of whose fields carry standard model quantum numbers. SUSY breaking is communicated to the standard model through gaugino masses and the Higgs multiplets. The model also provides a possible new solution of the strong ...

Approximate ripple carry adders (RCAs) and carry lookahead adders (CLAs) are presented which are compared with accurate RCAs and CLAs for performing a 32-bit addition. The accurate and approximate RCAs and CLAs are implemented using a 32/28nm CMOS process. Approximations ranging from 4to 20-bits are considered for the less significant adder bit positions. The simulation results show that approx...

For estimating delay parameters appearing in the CDMA (Code Division Multiple Access) model, several authors have proposed subspace-based solutions. Unfortunately, these methods , for example the eigenvector-based multiple signal clas-siication (MUSIC) method may yield poor results in noisy conditions. In this paper, we introduce subspace type delay estimation algorithms which are more eecient ...

One of the central problems in the eld of knowledge discovery is the development of good measures of in terestingness of discovered patterns Such measures of interestingness are divided into objectivemeasures those that depend only on the structure of a pat tern and the underlying data used in the discovery process and the subjective measures those that also depend on the class of users who exa...
