A statistical multiplexer is a basic model used in the design and the dimensioning of communication networks. The multiplexer model consists of a finite buffer, to store incoming packets, served by a single server with constant service time, and a more or less complicated arrival process. The aim is to determine the packet loss probability as a function of the capacity of the buffer. An exact a...

The classical sine-Gordon model is a two-dimensional integrable field theory, with particle like solutions the so-called solitons. Using its integra-bility one can define its quantum version without the process of canonical quantization. This bootstrap method uses the fundamental propterties of the model and its quantum features in order to restrict the structure of the scattering matrix as far...

An operational wildland fire model need to be robust and accurate. In this study, a physical model of fire spread is presented and used to perform simulation with an asynchronous method. The aim of this work is to provide an efficient simulation method capable of providing resutls in less than a minute and a resolution of a few meters using a physical model. The proposed simulation software is ...

One of the large industrial needs is use sound level meter (SLM) especially in noise monitoring even occupational and/or environmental, calibration this measuring device essential during last decades. The coupler approach regarded as most practical to apply SLM calibrating techniques required by standard IEC 61672. In method some tests have be accomplished judge measurement results. performed w...

Saat ini dunia mengalami perubahan cepat di lingkungan strategis yang serba bergejolak, kompleks, dan tidak pasti era VUCA. VUCA ( votality , uncertainity complexity ambiguity ) merupakan suatu kondisi dapat diprediksi berubah sehingga model saat dianggap mampu lagi menghadapi kompleksitas ketidakpastian (Mack et al., 2015). Amalia (2020) menambahkan semakin diperparah kehadiran wabah Covid-19 ...

The status of the theoretical research on the compressional modes of finite nuclei and the incompressibility K∞ of nuclear matter, is reviewed. It is argued that the recent experimental data on the Isoscalar Giant Monopole Resonance (ISGMR) allow extracting the value of K∞ with an uncertainity of about ± 12 MeV. Non-relativistic (Skyrme, Gogny) and relativistic mean field models predict for K∞ ...

Rule based systems are basically knowledge base systems. They imitate the functionalty of human decision making process in machines. The knowledge is stored in the Knowledge Base of the fuzzy rule based systems. The knowledge is expressed, manipulated and processed by using fuzzy logic. Fuzzy logic represents the human knowledge very well because its mathematical framework is very strong to dea...

1. Chromium sesquioxide (Cr2O3; 1.5 g/day) and [51Cr]chromic chloride [51CrCl3 (0.3 muCi/day)] were compared as continuously administered non-absorbed markers for the correction of faecal recoveries in 14 calcium balance studies each lasting at least 18 days. 2. The mean recoveries of each, 98.4% for Cr2O3 and 101.9% for 51CrCl3, were not significantly different from 100%. 3. The two markers re...

We propose in this paper to model of a rule based expert systems using the techniques of Fuzzy sets and Fuzzy logic. In the real world problem solving is the process of finding a solution when the path leading to that solution is uncertain. The Expert Systems need to have the ability to handle vague associations, for example by accepting the degree of correlations as numerical certainty factors...
