A formula to calculate the charge penetration energy that results when two charge densities overlap has been derived for molecules described by an effective fragment potential (EFP). The method has been compared with the ab initio charge penetration, taken to be the difference between the electrostatic energy from a Morokuma analysis and Stone’s Distributed Multipole Analysis. The average absol...

In mining frequent itemsets, one of most important algorithm is FP-growth. FP-growth proposes an algorithm to compress information needed for mining frequent itemsets in FP-tree and recursively constructs FP-trees to find all frequent itemsets. In this paper, we propose the EFP-growth (enhanced FPgrowth) algorithm to achieve the quality of FP-growth. Our proposed method implemented the EFPGrowt...

Este artigo apresenta semelhanças entre pontos centrais do pensamento e práticas educativas educador Paulo Freire fotodocumentarista João Roberto Ripper, tendo como base a experiência da Escola de Fotógrafos Populares (EFP) Agência vinculada à escola, localizadas no complexo favelas Maré, município Rio Janeiro. A EFP, uma iniciativa Observatório Favelas, destinou-se formação profissionalizante ...

In order to obtain the effect of material characteristics explosive on formation collinear explosively formed projectile (EFP)from warhead with dosuble liners, LS-DYNA simulation software was used simulate and analyze forming process EFP from five materials including pe4booster, PETN, TNT, C4 B explosives. The results indicate that increase density, detonation velocity, pressure, velocity lengt...

Due to the wider use of Function Point metrics in the software management field, there is an increasing need for methods to estimate, at an early stage of the software life cycle, a software application’s value in Function Points. This work describes how to use the Early Function Points method (presented at IFPUG 97, Scottsdale, September 97) from the practical point of view and it presents a s...

Growing availability of long-term satellite imagery enables change modeling with advanced spatio-temporal statistical methods. Multidimensional arrays naturally match the structure of spatio-temporal satellite data and can provide a clean modeling process for complex spatio-temporal analysis over large datasets. Our study case illustrates the detection of breakpoints in MODIS imagery time serie...

Research question How does the number of oocytes used affect cumulative live birth rate (CLBR) in endometriosis patients who had their vitrified for fertility preservation? Design Retrospective observational study including data from 485 women with underwent preservation January 2007 to July 2018. Survival curves and Kaplan–Meier plots were analyse CLBR according used. Endometriosis compared de...

The freezing and thawing process is a unique feature of the alpine permafrost ecosystem, which controls growth microorganisms meadows, plays vital role in animal husbandry development, ecosystem functions services. Meanwhile, also affected by external environmental factors, its spatial differences are very significant, especially regions over 5000 m a.s.l. In this study, periods Cuoma Township ...
