Heterogeneous composition of models of computation

A primitive execution model for heterogeneous modeling

Heterogeneous modeling is modeling using several modeling methods. Since many different modeling methods are used in different crafts, heterogeneous modeling is necessary to build a heterogeneous model of a system that takes the modeling habits of the designers into account. A model of computation is a formal description of the behavioral aspect of a modeling method. It is the set of rules that...

An efficient non-repudiation billing protocol in heterogeneous 3G-WLAN networks

The wireless communication with delivering variety of services to users is growing rapidly in recent years. The third generation of cellular networks (3G), and local wireless networks (WLAN) are the two widely used technologies in wireless networks. 3G networks have the capability of covering a vast area; while, WLAN networks provide higher transmission rates with less coverage. Since the two n...

Composition de modèles pour la modélisation multi-paradigme du comportement des systèmes. (Composition of models for the multi-paradigm modeling of the behavior of systems)

In the context of Model Driven Engineering, the use of multiple modeling paradigms for developing complex systems is both unavoidable and essential. It results in the heterogeneity of the models representing the considered system and makes global reasoning about the system difficult. The objective of multi-paradigm modeling is to ease the joint use of heterogeneous models during the development...

Experimental and theoretical studies on efficient regeneration of carbonyl compounds from oximes under green, mild and completely heterogeneous nanocatalysis

New type of heterogeneous nanocatalyst for deoximation based on Tungsten oxide supported on mesoporousmolecular sieve MCM-41 was developed. This new system representes inexpensive and highly activeheterogeneous nanocatalyst for deoximation under green and mild reaction conditions.

Analysis of Realized Volatility in Tehran Stock Exchange using Heterogeneous Autoregressive Models Approach

Objective: The present study aims atinvestigating the behavior of realized volatility for high-frequency data of Tehran Stock Index from April28th, 2012 to August 8th, 2018. Methods: Three different types of HAR models including of HAR-RV-CJ, HAR-RV and HAR-RVJ were used to analyze the Realized Volatility. Results: The obtained results of three diverse models revealed that the estimated Reali...
