Radiolysis compounds in bacon and chicken. Final report 18 Sep 81-20 Sep 82  

Energy Technology Data Exchange (ETDEWEB)

The results of this study are in agreement with the precepts established in studies published previously on beef, chicken, ham, and pork. The radiolysis compounds from bacon, chicken, ham, and pork are comparable in identity and amounts to those found in irradiated beef for comparable compositions and irradiation parameters (temperature, dose, etc.). The results of this study support the conclusions drawn in the CORC report of 'commonality in chemistry, predictability of products, and extrapolation of results.' Consequently, the same conclusions can be drawn concerning the wholesomeness of irradiated bacon, chicken, ham, and pork as for other irradiated meat products of similar composition and irradiation parameters as reported in the FASEB report and its supplements (I and II) on irradiated beef.

Hamming Weights in Irreducible Cyclic Codes  

CERN Document Server

Irreducible cyclic codes are an interesting type of codes and have applications in space communications. They have been studied for decades and a lot of progress has been made. The objectives of this paper are to survey and extend earlier results on the weight distributions of irreducible cyclic codes, present a divisibility theorem and develop bounds on the weights in irreducible cyclic codes.

A multi-criteria interval-valued intuitionistic fuzzy group decision making with Choquet integral-based TOPSIS  

British Library Electronic Table of Contents (United Kingdom)

An extension of TOPSIS, a multi-criteria interval-valued intuitionistic fuzzy decision making technique, to a group decision environment is investigated, where inter-dependent or interactive characteristics among criteria and preference of decision makers are taken into account. To get a broad view of the techniques used, first, some operational laws on interval-valued intuitionistic fuzzy values are introduced. Based on these operational laws, a generalized interval-valued intuitionistic fuzzy geometric aggregation operator is proposed which is used to aggregate decision makers? opinions in group decision making process. In addition, some of its properties are discussed. Then Choquet integral-based Hamming distance between interval-valued intuitionistic fuzzy values is defined. Combining ...

On Sums of Generating Sets in (Z_2)^n  

CERN Document Server

Let A and B be two affinely generating sets of (Z_2)^n. As usual, we denote their Minkowski sum by A+B. How small can A+B be, given the cardinalities of A and B? We give a fairly tight answer to this question. Our bound is attained when both A and B are unions of cosets of a certain subgroup of (Z_2)^n. These cosets are arranged as Hamming balls, the smaller of which has radius 1. By similar methods, we reprove the Freiman-Ruzsa theorem in (Z_2)^n, with an optimal upper bound. Denote by F(K) the maximal spanning constant || / |A|, over all subsets A of (Z_2)^n with doubling constant |A+A| / |A| < K. We explicitly calculate F(K), and in particular show that 4^K / 4K < F(K) (1+o(1)) < 4^K / 2K. This improves the estimate F(K) = poly(K) 4^K, found recently by Green and Tao and by Konyagin.

Binary Error Correcting Network Codes  

CERN Document Server

We consider network coding for networks experiencing worst-case bit-flip errors, and argue that this is a reasonable model for highly dynamic wireless network transmissions. We demonstrate that in this setup prior network error-correcting schemes can be arbitrarily far from achieving the optimal network throughput. We propose a new metric for errors under this model. Using this metric, we prove a new Hamming-type upper bound on the network capacity. We also show a commensurate lower bound based on GV-type codes that can be used for error-correction. The codes used to attain the lower bound are non-coherent (do not require prior knowledge of network topology). The end-to-end nature of our design enables our codes to be overlaid on classical distributed random linear network codes. Further, we free internal nodes from having to implement potentially computationally intensive link-by-link error-correction.
