THRESHOLD LOGIC IMPLEMENTATIONS: THE EARLY DAYS



I. INTRODUCTION
Research on neural networks (NNs) goes back sixty years.
The seminal year for the science of mind was 1943 when
the paper of McCulloch and Pitts was published . They
introduced the first mathematical model of a neuron
operating in an all-or-none fashion: the threshold logic (TL)
gate (TLG). It computes the sign of the weighted sum of its
inputs: f(X) = sign ( i = 1 n wi xi ), wi being the synaptic
weight as ....etc

This report addresses the problem of software correction of spatially variant blur in digital images. The problem arises when the camera optics contains flaws, when the scene contains multiple moving objects with different relative motion or the camera itself is i.e. rotated. Compensation through deconvolving is impossible due to the shift-variance in the PSF hence alternative methods are required. There are a number of suggested methods published. This report evaluates two method

matlab code energy based spectrum sensing in cognitive radio energy threshold based algorithm

ABSTRACT

Spectrum sensing is the basic and essential mechanisms of Cognitive Radio (CR) to find the unused spectrum. This paper presents an overview of CR architecture, discusses the characteristics and benefits of a CR. Energy detection based spectrum sensing has been proposed and used widely because it doesn't require transmitted signal properties, channel information, or even the type of modulation. In this paper, a survey of energy detector over ....etc

Locally Adaptive Passive Error Concealment
for Wavelet Coded Images

Joost Rombaut, Aleksandra Pi zurica, Member, IEE, and Wilfried Philips, Member, IEE



Abstract

This letter presents a novel locally adaptive error concealment
method for subband coded images. For each lost low-frequency
coefficient, we estimate the optimal interpolation weights
from its neighborhood. The calculation of the interpolation weights
is optimized in the mean squared error sense, and it takes into account
the error ....etc

Abstract
Low-voltage operation for memories is attractive because of lower leakage power and active energy, but the challenges of SRAM design tend to increase at lower voltage. This paper explores the limits of low-voltage operation for traditional six transistor (6 T) SRAM and proposes an alternative bitcell that functions to much lower voltages. Measurements confirm that a 256-kb 65-nm SRAM test chip using the proposed bitcell operates into ....etc

Threshold Multi signature Scheme Project:
The main aim of this abstract is presenting secure and efficient way of Threshold multi signature scheme. The fundamental properties are defined in this scheme consist the all properties of the multi signature and thresh hold group signatures.

Existing System:

For the generation of digital signature more shareholders are required. The shareholders must contribute equally to produce valid digital signatures.The scheme consist the all properties of the multi signat ....etc

quality threshold clustering algorithm implementation source code

Abstract

Quality Threshold Clustering (QTC) is an algorithm for partitioning data, in fields such as biology, where clustering of large data-sets can aid scientific discovery. Unlike other clustering algorithms, QTC does not require knowing the number of clusters a priori, however, its perceived need for high computing power often makes it an unattractive choice. This paper presents a thorough study of QTC. We analyze the worst case complexity of the algorithm and discuss metho ....etc

A Fully Distributed Proactively Secure Threshold-Multisignature Scheme



INTRODUCTION
IN distributed systems it is sometimes necessary for users
to share the power to use a cryptosystem , . The
system secret is divided up into shares and securely stored
by the entities forming the distributed cryptosystem. The
main advantage of a distributed cryptosystem is that the
secret is never computed, reconstructed, or stored in a
single location, making the secret more difficu ....etc
