In this paper, we propose a class of linear codes and obtain their weight distribution. Some of these codes are almost optimal. Moreover, several classes of constant composition codes(CCCs) are constructed as subcodes of linear codes.

Market Year Average (MYA) prices enter into payment calculations for Price Loss Coverage (PLC) and Agricultural Risk Coverage (ARC), two commodity program alternatives available in the 2013 Farm Bill (see here for more details). The distribution of MYA prices will influence payment levels under both programs. Hence, quantifying the potential MYA price distributions is important for evaluating c...

Under a flexible exchange rate regime, the Canadian economy is constantly affected by fluctuations in exchange rates. This paper focuses on the effect of the exchange rate on employment in Canada. We find that appreciation of the Canadian dollar has significant effects on employment in manufacturing industries; such effects are mostly associated with the export-weighted exchange rate, but not t...

BACKGROUND In Australia, sport is saturated by the promotion of junk food, alcohol and gambling products. This is particularly evident on player jerseys. The effect of this advertising on children, who are exposed to these messages while watching sport, has not been thoroughly investigated. The aim of this research study was to investigate: (1) the extent to which children implicitly recalled s...

In this paper we study Z2Z4Z8-additive codes, which are the extension of recently introduced Z2Z4-additive codes. We determine the standard forms of the generator and parity-check matrices of Z2Z4Z8-additive codes. Moreover, we investigate Z2Z4Z8-cyclic codes giving their generator polynomials and spanning sets. We also give some illustrative examples of both Z2Z4Z8-additive codes and Z2Z4Z8-cy...

This article lays the conceptual foundations for the study of the market value of information commodities. The terms “information” and “commodity” are given precise definitions in order to characterize “information commodity,” and thus to provide a sound basis for examining questions of pricing. Information is used by marketplace actors to make decisions or to control processes. Thus, we define...

This paper uses the parallel calculation of the radiation integral for examination of performance and compiler issues on a Beowulf-class computer. This type of computer, built from mass-market, commodity, of-the-shelf components, has limited communications performance and therefore also has a limited regime of codes for which it is suitable. This paper first shows that this code falls within th...

JavaSpaces provides a simple yet expressive mechanism for distributed computing with commodity technology. We discuss the suit-ability of JavaSpaces for implementing diierent classes of concurrent computations based on low-level metrics (null messaging and array I/O), and present performance results for several parametric algorithms. We found that although ineecient for communication intensive ...
