Progressing towards an era of ever more small devices with computational power and storage capabilities, a new kind of security approach is needed. We propose a practical scheme to achieve threshold security for Things That Think. The private data of the user remains protected as long as the number of corrupted devices is lower than the threshold. We describe a procedure for key distribution, k...

Causal independence modelling is a well-known method both for reducing the size of probability tables and for explaining the underlying mechanisms in Bayesian networks. Many Bayesian network models incorporate causal independence assumptions; however, only the noisy OR and noisy AND, two examples of causal independence models, are used in practice. Their underlying assumption that either at lea...

estimation of weed damage threshold is essensial in site-specific weed control programs. this experiment was conducted to determine the spatial distribution of weeds damage threshold in two wheat feilds. data related to weed biomass and crop yield were collected from sampling at 120 and 135 points of the first and second fields respectively based on a 4×4 m grid at research field of agricultura...

the ability to taste phenylthiocarbamide (ptc), a bitter organic compound, described as a bimodal autosomal trait is widely used to know the heritable trait in both genetic and anthropological studies. the present study was carried out to analyze the prevalence of ptc taste sensitivity and to determine the gene frequencies among some muslim populations of uttar pradesh, india. this study has so...

autoselection is a kind of natural selection, that occurs in reproductive traits by inequality of offspring generation and therefore by virtue of the nature of its genes transmission to next generations. in this study, the effects of autoselection on heritability and selection response in reproductive traits by using univariate stochastic computer simulation in artificial selected and unselecte...

We present an exact analysis of the physical properties of bimodal networks specified by the two peak degree distribution fully incorporating the degree-degree correlation between node connections. The structure of the correlated bimodal network is uniquely determined by the Pearson coefficient of the degree correlation, keeping its degree distribution fixed. The percolation threshold and the g...

Start from the network with given degree distribution and inter-connection probability matrix, we rewire the edges of network and get different correlated networks. And do the epidemic spreading on these networks numerically through Monte-carlo methods. The results show that the spreading threshold is not necessarily correlate to the type of connections of the network.

We introduce a random bit-string model of post-transcriptional genetic regulation based on sequence matching. The model spontaneously yields a scale free network with power law scaling with γ = −1 and also exhibits log-periodic behaviour. The in-degree distribution is much narrower, and exhibits a pronounced peak followed by a Gaussian distribution. The network is of the smallest world type, wi...

| This paper presents a group-oriented (t;n) threshold cryptosystem in which the sender determines the threshold parameter t and selects the group of intended receivers. The proposed scheme is practical, eecient and non-interactive. It does not need any trusted clerks or trusted key distribution centers. The security of the scheme is equivalent to the security of the original ElGamal cryptosystem.
