The use of nonparametric contrasts in one-way layouts and random block designs

Nonparametric simple-contrast estimates for one-way layouts based on Hodges-Lehmann estimators for two samples and confidence intervals for all contrasts involving only two treatments are found in the literature.Tests for such contrasts are performed from the distribution of the maximum of the rank sum between two treatments. For random block designs, simple contrast estimates based on Hodges-Lehmann estimators for one sample are presented. However, discussions concerning the significance levels of more complex contrast tests in nonparametric statistics are not well outlined.This work aims at presenting a methodology to obtain p-values for any contrast types based on the construction of the permutations required by each design model using a C-language program for each design type. For small samples, all possible treatment configurations are performed in order to obtain the desired p-value. For large samples, a fixed number of random configurations are used. The program prompts the input of contrast coefficients, but does not assume the existence or orthogonality among them.In orthogonal contrasts, the decomposition of the value of the suitable statistic for each case is performed and it is observed that the same procedure used in the parametric analysis of variance can be applied in the nonparametric case, that is, each of the orthogonal contrasts has a chi(2) distribution with one degree of freedom. Also, the similarities between the p-values obtained for nonparametric contrasts and those obtained through approximations suggested in the literature are discussed.

Transição para um novo centro de distribuição logístico em uma indústria de confecção

In a highly competitive environment for manufacturers and retailers in the garment sector, flexible solutions for warehousing, distribution and exhibition of products directly influence the cost and responsiveness to market demands. This work refers to a Textile/Clothing, which undergoes a process of restructuring and growth, where we evaluated the need for professionalism in all its processes, so that the high demands were met in a sales perennial. Thus, this study aims to identify and analyze possible improvements in the process of transition from a logistics/manufacturing force in a Textile/Clothing in existence since 1998, located in São Paulo, a framework for a new logistics Center Distribution Logistics. The theoretical basis of the research literature addresses as Distribution Center and its basic functions, layout and performance indicators. As result it was mapped the current logistics processes, contributing directly to the development of the layout of the new Distribution Center. Have also been established KPI,s ( Key Performance Indicator) and Logistics Performance Indicators showing the actual process performance, helping professionals in make decisions

Proposta de traçado de alcoolduto ligando a hidrovia Tietê Paraná à refinaria do planalto paulista com uso de avaliação multicritérios e geotecnologias

From the beginning of the century, with the advent of the flex fuel car, successor fluctuations in oil prices and the rise of awareness of the impending shortage of fossil fuels, the alcohol sector begins to reappear in the panorama of national economy making Brasill reaches the point of becoming a leading exporter of this product. Ethanol assumed the role of such importance in Brazilian exports, which Petrobras through the Growth Acceleration Program (PAC) has made investments in the Brazilian pipeline network to better ensure the production of ethanol to major ports. The means of transport in pipelines are safe and inexpensive, but require careful evaluation in its implementation, they may lead to negative social and environmental impacts. Thus, the purpose of this project is to propose the best route for an ethanol pipeline connectin the Tietê-Paraná, leaving the municipality of Santa Maria da Serra (SP), to the Planalto Paulista Refinery (REPLAN), located in Paulinia (SP), belonging to the passage of ethanol export corridor, currently under revelopment. The technique used for the development of the stroke is the association of multicriteria evaluation, the geographical information system (SIG) and geotechnologies. This study presented three possible layouts for the ethanol pipeline, highlighting the best option, in addition, demonstrated the suitability of the area to receive projects of similar nature to a pipeline

Bulas e Cartelas de Medicamentos: Possíveis soluções de leiturabilidade através do Design Gráfico

The package inserts for drugs represent the main source of written information provided to patients, but the deficiency in the page layouts of informational texts (readability), the excess of information and use of techno-scientific language hamper the effectiveness of communication between the author (manufacturer) and player (patient) in addition to the physiological conditions of patients are often elderly. This article discusses these issues from theoretical predictions, and proposes solutions to the adequacy of information graphics package inserts of drugs and facilitating the identification of drug cards.
