We are facing one of the economic sectors that annually reports most occupational accidents to riskmanagers in our country, construction sector. Through a statistical analysis supported by figures provided theFederation Insurers Colombia - Fasecolda, we argue need for country place special emphasis on thesupervision health and safety sector, sector Despite presenting high mortalityrates, especi...

Envelopment Analysis (DEA) is a very eective method to evaluate the relative eciency of decision-making units (DMUs). DEA models divided all DMUs in two categories: ecient and inecientDMUs, and don't able to discriminant between ecient DMUs. On the other hand, the observedvalues of the input and output data in real-life problems are sometimes imprecise or vague, suchas interval data, ordinal da...

The use of hydroponics is an effective way to carry out farming activities without theneed for large tracts land. Hydroponics requires extra supervision be able produceplants with good quality. There are three main parameters in hydroponics, namely the amountof dissolved nutrient content, pH level water, and water suhue level. To provideconvenience conducting surveillance, this research designe...

Inthis paper, we present a context-based information refinding system called ReFinder. It leverages human’s natural recall characteristics and allows users to refind files and Web pages according to the previous access context. ReFinderrefinds information based on a query-by-context model over a context memory snapshot, linking to the accessed information contents. Context instances in the memo...

The Symmetric permutation group S2n is a classical algebraic object that also used in Computer science, Coding theory, Statistics, etc. In particular, the coding theory considers codes defined on symmetric Sn or its subgroups. research of has been started from 1970s. These can be obtained with using different distances: Hamming, Ulam, Cailey, Levenshtein. finding distance permutations depends t...

The purpose of this study is to discuss the theory social interest which was coined by Adler.

Propene dissociation channels were characterized by ab initio CCSD(T)/6-311++g(d,p) calculations. Inthis work the detailed mechanism of propene dissociation to C2H4+CH2, C2H2+H+CH3, C2H2+CH4 andC3H3+H2+H have been investigated. According to our calculations, ten fragments can be classified intofive dissociated channels. Our results point out that two mechanisms come into play in the H2 eliminat...
