Vegetables are vital to the human diet, and in particular provide well-known nutrients maintain normal physiological functions. The prolonged application of large amount pesticides has resulted heavy metal accumulation vegetable farms. Exposure metals by consumption contaminated vegetables its toxicity is a serious concern. This article reviews effect pesticides, metals, vegetables, soil transf...

In 1994 Benaloh and de Mare introduced the notion of one way accumulators that allow to construct eecient protocols for proving membership in a list and related problems like time stamping and authentication. As required by Benaloh et al. unlike in signature based protocols no central trusted authority is (should be) needed. Accumula-tor based protocols do further improve on hash tree based pro...

In this paper the ensemble of codes formed by a serial concatenation of a repetition code with multiple accumulators connected through random interleavers is considered. Based on finite length weight enumerators for these codes, asymptotic expressions for the minimum distance and an arbitrary number of accumulators larger than one are derived using the uniform interleaver approach. In accordanc...

Cryptographic accumulators have often been proposed for use in security protocols, and the theoretical runtimes of algorithms using them have been shown to be reasonably efficient, but their performance in the real world has rarely been measured. In this paper I analyze the performance differences between two cryptographic accumulator constructions, RSA accumulators and bilinear-map accumulator...

In this paper we consider the ensemble of codes formed by a serial concatenation of a repetition code with multiple accumulators through uniform random interleavers. Based on finite length weight enumerators for these codes, asymptotic expressions for the minimum distance and an arbitrary number of accumulators larger than one are derived. In accordance with earlier results in the literature, w...

Many important multimedia applications contain a signifcant fraction of reduction operations. Although, in general, multimedia applications are characterized for having high amounts of Data Level Parallelism, reductions and accumulations are dificult to parallelize and show a poor tolerance to increases in the latency of the instructions. This is specially signifcantfor p-SIMD extensions such a...

Many important multimedia applications contain a significant fraction of reduction operations. Although, in general, multimedia applications are characterized for having high amounts of Data Level Parallelism, reductions and accumulations are difficult to parallelize and show a poor tolerance to increases in the latency of the instructions. This is specially significant for -SIMD extensions suc...
