Discovery of a network topology is a challenging task. Available algorithms that rely on simple hop-limited, traceroute-style probes give different performance in terms of the completeness (fuzziness) of the resulting map, the speed of mapping, and the efficiency of mapping. In this paper, the authors provide a brief overview of the types of mapping abstractions that have been used and review a...

This paper presents formal techniques for analysis of executions of organizational scenarios based on processoriented models of organizations. A part of these techniques is dedicated to establishing the correspondence between formalized executions (i.e., traces) and process-oriented models. Other techniques provide the analyst with wide possibilities to analyze organizational dynamics and to ev...

In this paper the possibility of human mind modeling is discussed. According the recent knowledge from cognitive and neurology sciences we inspect the human brain principles. Position of natural language (NL) is outlined alongside its connection with human senses. As a result the Theory of three layers (TTL) is introduced. Arguments from the Incompleteness theory are used to support its own tru...

The new Directed Reverse Path Join (DRPJ) protocol efficiently implements a Greedy routing algorithm for generating a multicast tree. The DRPJ protocol minimizes the messaging overhead from probe messages and allows a joining node to find multiple paths that are not constrained to be only the shortest paths. This enables a controllable tradeoff between path length and bandwidth consumption. Usi...

Unlike the designs of common zoom lenses in literature, mobilephone applications demand an extremely short total track length (TTL), less around 10 mm. This short TTL request makes the zoom lens design of mobile phones unique. Also in viewing the cost advantage of CMOS sensor, we explore the mobilephone camera zoom lens with typical CMOS sensor format by global explorer (GE) optimization as wel...

The misuse of sulfadiazine (SFZ) has led to great hazard the environment and human safety; therefore, a simple, rapid, sensitive method detect is urgently needed. Herein, we report simple fabrication for rare earth vanadate samarium (SmV)-doped covalent organic framework COFTDBA-TTL nanocomposites (SmV/COFTDBA-TTL), which were used construct electrochemical sensor. synergistic effect arising fr...
