This paper presents a scheme using Differential Evolution based Functional Link Artificial Neural Network (FLANN) to predict the Indian Stock Market Indices. The Model uses Back-Propagation (BP) algorithm and Differential Evolution (DE) algorithm respectively for predicting the Stock Price Indices for one day, one week, two weeks and one month in advance. The Indian stock prices i.e. BSE (Bomba...
Purpose of the work: The work was aimed at the study of the changes of the system of hemostasis and of blood rheology during the progression of infection in patients with lower-limb and facial erysipelas and to validate the advisability of replacement and/or antithrombotic therapy. Material and methods: the author studied the indices of external (time of prothrombin (PT), international normaliz...
Functional diversity (FD) is an important component of biodiversity that quantifies the difference in functional traits between organisms. However, FD studies are often limited by the availability of trait data and FD indices are sensitive to data gaps. The distribution of species abundance and trait data, and its transformation, may further affect the accuracy of indices when data is incomplet...
Statement of Problem: Considerable response to functional orthopedic appliances treatment in class II skeletal patients occurs during pubertal growth spurt. Therefore, it seems necessary to investigate indices indicating mandibular growth pattern. It has been proved that analyzing cervical vertebral maturation stage is a more valid index than that of hand wrist. Purpose: The aim of this study w...
Background and Objectives: Probiotic foods include therapeutic characteristics such as anti diarrhea, cancer and pediatric infections characteristics as well as improving lactose digestion. In this study, addition of hazelnut (15%) with lactobacillus casei (108 log CFU/g) for the introduction of probiotic butters with hazelnut powder was investigated. Materials & Methods: Butter samples (500 ...
Entropy measures of probability distributions are widely used measures in ecology, biology, genetics, and in other fields, to quantify species diversity of a community. Unfortunately, entropy–based diversity indices, or diversity indices for short, suffer from three problems. First, when computing the diversity for samples withdrawn from communities with different structures, diversity indices ...
Ecosystem management policies increasingly emphasize provision of multiple, as opposed to single, ecosystem services. Management for such "multifunctionality" has stimulated research into the role that biodiversity plays in providing desired rates of multiple ecosystem processes. Positive effects of biodiversity on indices of multifunctionality are consistently found, primarily because species ...
It is by now well known that the Boltzmann-Gibbs (BG) entropy can be usefully generalized using the non-extensive entropies, which have been applied to a wide range of phenomena. However, it seems that even more general entropies could be useful in order to describe other complex physical systems, a task which has already been undertaken in the literature. Following this approach, we introduce ...
Expressed sequence tags (ESTs) have provided a first glimpse of the collection of transcribed sequences in a variety of organisms. However, a careful analysis of this sequence data can provide significant additional functional, structural and evolutionary information. Our analysis of the public EST sequences, available through the TIGR Gene Indices (TGI; http://www.tigr.org/tdb/tdb.html ), is a...
April 16, 2010 Type Package Title Measuring functional diversity (FD) from multiple traits, and other tools for functional ecology Version 1.0-9 Date 2010-04-16 Author Etienne Laliberté, Bill Shipley Maintainer Etienne Laliberté Description FD is a package to compute different multidimensional FD indices. It implements a distance-based framework to measure FD that a...
