The paper discusses the development of an IBM PC based tool, for calculating train braking distances for various train classes on a rail network. There is discussion on current industry practice and the limitations of that practice, the concept of the tool itself, including the assumptions made, the strategy adopted to minimise the risk of incorrect calculations, and the results of adopting tha...

A further commercially available encryption package for the IBM PC is analysed, and a simple breaking program is described.

The food-borne pathogen Listeria monocytogenes proliferates at refrigeration temperatures, rendering refrigeration ineffective in the preservation of Listeria-contaminated foods. The uptake and intracellular accumulation of the potent compatible solutes glycine betaine and carnitine has been shown to be a key mediator of the pathogen's cold-tolerant phenotype. To date, three compatible solute s...

The aim of this paper is to prove a common fixed point theorem for variants of weak compatible maps in a complex valued metric space. As a consequence, we extend and generalize the theorem of Branciari [3] for 2812 a pair of weakly compatible mappings satisfying a general contractive condition of integral type in complex valued metric space. At last, we prove two results by using E.A. property ...

We present a new method, called UTA, for multiple criteria ranking of alternatives from set A using a set of additive value functions which result from an ordinal regression. The preference information provided by the decision maker is a set of pairwise comparisons on a subset of alternatives A A, called reference alternatives. The preference model built via ordinal regression is the set of all...

We show that fusion categories Rep(kστT ) of representations of the weak Hopf algebra coming from a vacant double groupoid T and a pair (σ, τ ) of compatible 2-cocyles are group-theoretical.

In this paper, we prove common fixed point theorems of Gregus type for three discontinuous and weak compatible mappings in convex metric spaces. We improve, extend and generalize some well known results by many authors
