The problem of efficient computing of binary and ternary positive (or zero) polarity Reed-Muller (PPRM) transform is important for many areas. The matrices, determining these transforms, are defined recursively or by Kronecker product. Using this fact, we apply the dynamic-programming strategy to develop three algorithms. The first of them is a new version of a previous our algorithm for perfor...

This study deals with the application of Fuzzy AHP method for evaluating Green supply chain management strategies for cement manufacturing company. The strategies are calculated by the model of Fuzzy AHP, the main attributes, sub attributes and measurement indicators are defined based on the cement manufacturing process. The weights are calculated based on the pair-wise comparison of matrices o...

The main result of this article is that for collections of entry-wise non-negative matrices the property of possessing a standard triangularization is stable under approximation. The methodology introduced to prove this result allows us to offer quick proofs of the corresponding results of [B. R. Yahaghi, Near triangularizability implies triangularizability, Canad. Math. Bull. 47, (2004), no. 2...

A celebrated 1942 result of Schoenberg characterizes all entry-wise functions which preserve positivity of matrices of any size. I will present a characterization of polynomials which preserve positivity when applied entry-wise on matrices of a fixed dimension. All put in historical context and motivated by recent demands of statistics of large data and optimization theory. A sketch of the proo...

A novel type of material encapsulating phase-change materials (PCMs) is reported concerning their implication for use as thermal energy storage devices. The composites of siliceous SBA-15 or carbonaceous CMK-3 mesoporous assemblies and organic PCMs could be used to make leak-free devices that retain their capabilities over many thermal cycles for heat storage/release. A confinement effect was o...

Over the past two decades, it has become widely accepted that phylogenies need to be incorporated into statistical analyses of interspecific data. However, recent debate has focused on whether it is appropriate to apply phylogenetic comparative methods (PCMs) to the study of adaptation. Although some of the criticisms are serious, it is premature to stop applying PCMs altogether. New statistica...

 This paper deals with measuring inconsistency and incompatibility of pair-wise comparison matrix with fuzzy elements. Here we deal with some properties of such pair-wise comparisons, particularly, reciprocity consistency and compatibility. Moreover, we show how to measure it defining two new indices. The first index of inconsistency is based on the classical concept of consistency, however, i...

PCMs have always been viewed as a suitable candidate for off peak thermal storage, particularly for refrigeration systems, due to the high latent energy densities of these materials. However, due to the need to have them encapsulated within a container this density is reduced. Furthermore, PCMs have a low thermal conductivity which reduces the useful amount of energy which can be stored. To con...

In this paper we investigate the extent to which Katz backoff language models can be compressed through a combination of parameter quantization (width-wise compression) and parameter pruning (length-wise compression) methods while preserving performance. We compare the compression and performance that is achieved using entropy-based pruning against that achieved using only parameter quantizatio...

Thermal energy storage based on phase change materials (PCMs) can improve the efficiency of utilization by eliminating mismatch between supply and demand. It has become a hot research topic in recent years, especially for cold thermal (CTES), such as free cooling buildings, food transportation, electronic cooling, telecommunications etc. This paper summarizes latest progress PCMs-based CTES.
