In order to study the compatibility of some theoretical models referring to the size effects on the fracture parameters relative to the experimental data, some experimental results [1], [2], referring to the tensile strength σN, critical strain wu, and to the fracture energy GF of some concrete and rock specimens, respectively, were studied by means of the procedures of the numerical analysis [...

In this research, creation of higher mechanical natural fiber mat composites was proposed. The hybrid mat with jute and glass mat was fabricated by needle punching system, in which jute mat was placed on glass mat. The ratio of jute and glass mat layers was set to be 1:0,1:1,1:2 and 2:1, respectively. The composites were fabricated by hand-lay up method with unsaturated polyester resin after ne...

This study examines the potential of Grammatical Evolution to uncover a series of useful rules which can assist in predicting corporate failure using information drawn from financial statements. A sample of 178 publically quoted, failed and non-failed US firms, drawn from the period 1991 to 2000 are used to train and test the model. The preliminary findings indicate that the methodology has muc...

A proof is presented that shows that the number of directions determined by a function over a finite field GF (q) is either 1, at least (q+3)/2, or between q/s+1 and (q − 1)/(s − 1) for some s where GF (s) is a subfield of GF (q). Moreover the graph of those functions that determine less than half the directions is GF (s)−linear. This completes the unresolved cases s = 2 and s = 3 of the main t...

the verb in russian language is a part of speech which involves several grammatical features. regarding methods of expressing the person, we can classify it in two major groups: personal verbs and non-personal verbs. the difference of these two groups is in their expression and inexpression of the person as a grammatical category. the purpose of this research is to consider ways of declaring th...

A partition u of [k] = f1; 2; : : : ; kg is contained in another partition v of [l] if [l] has a k-subset on which v induces u. We are interested in counting partitions v not containing a given partition u or a given set of partitions R. This concept is related to that of forbidden permutations. A strengthening of Stanley{Wilf conjecture is proposed. We prove that the GF counting v is rational ...
