A lattice (d, k)-polytope is the convex hull of a set of points in dimension d whose coordinates are integers between 0 and k. Let δ(d, k) be the largest diameter over all lattice (d, k)-polytopes. We develop a computational framework to determine δ(d, k) for small instances. We show that δ(3, 4) = 7 and δ(3, 5) = 9; that is, we verify for (d, k) = (3, 4) and (3, 5) the conjecture whereby δ(d, ...

The role of yeast in wine quality is very important. use selected autochthonous yeasts becoming more and frequent enology, not only to obtain a diversification wines, but also as link between the its territory origin. objectives this work were test two indigenous cellar on pilot scale. strain Saccharomyces cerevisiae paradoxus previously isolated vineyard Piedmont (Italy). Studying oenological ...

Postharvest pruning generates large amounts of vine-shoots (VSs) that are used as a domestic fuel or burned in the field, resulting release CO2 and NO2. Its use raw material for preparation activated carbons (ACs) turns VS into high added-value product. In this work, ACs have been prepared from by physical chemical activation. The discoloring deodorant capacity these has analyzed correlated wit...

In this paper we introduce and investigate similarity measures for convex polyhedra based on Minkowski addition and inequalities for the mixed volume, volume and surface area related to the Brunn-Minkowski theory. All measures considered are invariant under translations; furthermore, they may also be invariant under subgroups of the aane transformation group. For the case of rotation and scale ...

Driven by both technology and market, telecom industry is becoming a part of several converged industries in information society gradually from an independent industry which provides telecom products like voice or data. Under such background, this paper introduces a new value chain model of telecom value-added services in the new environment, providing theoretic support for transformation of te...

Additive Number Theory can be best described as the study of sums of sets of integers. A simple example is given two subsets A and B of a set of integers, what facts can we determine about A + B where A + B := {a + b | a ∈ A and b ∈ B}? We will state a result regarding this example shortly. We note that a very familiar problem in Number Theory, namely Lagrange’s theorem that every nonnegative i...

Pozega-Slavonia County has a long tradition of viticulture and oenology at which it becomes ever more recognizable. Although this is the economic segment of high importance for the local economy and regional development this study has shown that there is low percentage of representation in relation to the total agriculture potential of the county. In Republic of Croatia there are counties with ...
