forest ecosystems that have spent a long time to mature, offer important goods and services to humanity. hence, utilization and exploitation of these resources should be based on careful assessment of their ecological value and potential. ecological land evaluation is an approach based on land quality, vulnerability and potential assessment for different acceptable uses drawing upon related mod...

The triply periodic minimal surface lattice structure is innovatively introduced into the design of flexure hinges in this paper. Four types lattices are generated by approximate mathematical expressions. compliance characteristics these four simulated finite element analysis (FEA), and it found that primitive (P-lattice) most suitable for hinges. Simplified model single P-lattice one-dimension...

The method of Boolean function representation in terms positional logic algebra compact operator form is offered. Compared with the known method, it uses position operators a complexity no more than two and only one type equivalent transformations. less labor intensive. It allows parallelizing calculations. corresponding way implementation developed. competes some ways hardware complexity, reso...

A group in which every element is its own inverse is called a boolean group. We show that if G is an infinite boolean group, then there exist subsets A,B of G such that |A| = |B| = |G| and G \ {0} is the direct sum of A and B, i.e., for each (a, b) ∈ A × B, a + b = 0 and for each nonzero element g ∈ G, there exists a unique pair (a, b) ∈ A×B such that g = a + b. A variant of this result also is...

JSON Schema is a schema language for documents, based on complex combination of structural operators, Boolean operators (negation included), and recursive variables. The static analysis documents comprises practically relevant problems, including satisfiability, inclusion, equivalence. These problems can be reduced to witness generation: given schema, generate an element the --- if it exists re...

Practical memristor came into picture just few years back and instantly became the topic of interest for researchers and scientists. Memristor is the fourth basic two– terminal passive circuit element apart from well known resistor, capacitor and inductor. Recently, memristor based architectures has been proposed by many researchers. In this paper, we have designed a hybrid Memristor-CMOS (MeMO...
