The subject of this study is the non-repudiation security service for network communication using TCP/IP stack. Generated evidence, as well decision-making process registering a given event, are context-aware. Non-repudiation equipped with context-awareness by widely utilized tools. aim paper to present timing results selected tools execution and complete evidence generation time. In some appli...

In this paper, we present the results of a longitudinal study for the evolution follow-up in writing among typical pupils in primary education. We propose a method aimed at discovering groups of pupils sharing the same handwriting strategies along their primary education. From the on-line acquisition of writing and drawing tests, writing strategies are modeled by means of a bayesian network. Ex...

For two nite disjoint sets P and Q of strings over an alphabet , an alphabet indexing for P;Q by an indexing alphabet with j j < j j is a mapping : ! satisfying ~ (P ) \ ~ (Q) = ;, where ~ : ! is the homomorphism derived from . We de ned this notion through experiments of knowledge acquisition from amino acid sequences of proteins by learning algorithms. This paper analyzes the complexity of nd...

Many applications are characterized by having naturally incomplete data on customers – where data on only some fixed set of local variables is gathered. However, having a more complete picture can help build better models. The naïve solution to this problem – acquiring complete data for all customers – is often impractical due to the costs of doing so. A possible alternative is to acquire compl...

SCADA refers to a large-scale, distributed measurement(and control) system. SCADA is not a specific technology, but a type of application. SCADA stands for Supervisory Control and Data Acquisition — any application that gets data about a system in order to control that system is a SCADA application. A SCADA application has two elements: 1. The process/system/machinery we want to monitor a contr...

This paper examines the steady states of an overlapping generations economy with a given distribution of household locations over a one-dimensional interval. Parents decide whether or not to educate their children. Educational decisions are affected by location: There are local complementarities in investment incentives stemming from aspirations formation, learning spillovers, or local public g...
