We introduce rational semimodules over semirings whose addition is idempotent, like the max-plus semiring. We say that a subsemimodule of the free semimodule Sn over a semiring S is rational if it has a generating family that is a rational subset of Sn, Sn being thought of as a monoid under the entrywise product. We show that for various semirings of max-plus type whose elements are integers, r...

We give exact and approximation algorithms for computing the Gromov hyperbolicity of an n-point discrete metric space. We observe that computing the Gromov hyperbolicity from a fixed base-point reduces to a (max,min) matrix product. Hence, using the (max,min) matrix product algorithm by Duan and Pettie, the fixed base-point hyperbolicity can be determined in O(n) time. It follows that the Gromo...

Increasingly, companies are creating product advertisements and catalog images using computer renderings of 3D scenes. A common goal for these companies is to create aesthetically appealing compositions that highlight objects of interest within the context of a scene. Unfortunately, this goal is challenging, not only due to the need to balance the trade-off among aesthetic principles and design...

to study the chemical composition and qualitative comparison of the pistachio by-products and the effect of pistachio hull tannin on its digestibility and gas production, four experiments were carried out. in the first experiment, nutrient composition, phenolic and tannin components of the ohadi, kaleghuchi and white varieties of pistachio by-product from dehulling process were measured. pistac...

The aim of the research is focused on researching perception quality products based dried vegetables, which influences consumer to buy halal food products. Three vegetables DO-DO spice, Vegedor and Tajna-supplement vegetable dishes were used for research. Halal product status was examined through composition, specification raw materials, supervision procurement process, validation production pr...

We present an updated cosmic-ray mass composition analysis in the energy range $10^{16.8}$ to $10^{18.3}$ eV from 334 air showers measured with LOFAR radio telescope, and selected for minimal bias. In this range, origin of cosmic rays is expected shift galactic extragalactic sources. The based on improved method infer depth maximum $X_{\rm max}$ extensive measurements shower simulations. show r...
