conclusions the composition of unrecorded samples did not raise major toxicological concern beyond ethanol in alcohol products. however, concentration levels of methanol in some unrecorded alcohol samples made these samples detrimental for human consumption. results of 877 reports of alcohol samples, more than 50% were obtained from mashhad and the rest were from the suburbs. of the reports, 57...

Abstract This paper presents a compositional modeling approach by means of (max,+) automata. The motivation is to be able to model a complex discrete event system by composing sub-models representing its elementary parts. A direct modeling of safe timed Petri nets using (max,+) automata is first introduced. Based on this result, two types of synchronous product of (max,+) automata are proposed ...

In this paper, we study the finitely many constraints of fuzzy relation inequalities problem and optimize the linear objective function on this region which is defined with fuzzy max-Lukasiewicz operator. In fact Lukasiewicz t-norm is one of the four basic t-norms. A new simplification technique is given to accelerate the resolution of the problem by removing the components having no effect on ...

fuzzy relation inequalities based on max-f composition are discussed, where f is a binary aggregation on [0,1]. for a fixed fuzzy relation inequalities system $ a circ^{f}textbf{x}leqtextbf{b}$, we characterize all matrices $ a^{'} $ for which the solution set of the system $ a^{' } circ^{f}textbf{x}leqtextbf{b}$ is the same as the original solution set. similarly, for a fixed matrix ...

Graphical models, such as Bayesian networks and Markov random elds, represent statistical dependencies of variables by a graph. The max-product \belief propagation" algorithm is a local-message passing algorithm on this graph that is known to converge to a unique xed point when the graph is a tree. Furthermore, when the graph is a tree, the assignment based on the xedpoint yields the most proba...

We consider a system A ◦ x b, where A ∈ Rm×n + is a non-negative matrix and b ∈ R+ is a non-negative vector over the n-dimensional variable l x u, where l, u ∈ R+ are lower and upper bounds, respectively, and ◦ is either a max–min or a maxproduct composition. It is shown that the set of minimal solutions of such systems can be computed in incremental quasi-polynomial time. © 2008 Elsevier B.V. ...

$r$-module. in this paper, we explore more properties of $max$-injective modules and we study some conditions under which the maximal spectrum of $m$ is a $max$-spectral space for its zariski topology.

this study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (pbpm) from two slaughterhouses in iran. samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. the amounts of calcium, phosphorus, sodium, potassium, magnesium, iron, manganese, copper and zinc were determined. the apparent metabolizable energy (...
