This paper describes two approaches to the problem of automatically placing document items on pages of some output device. Both solutions partition the page into regions where each item is to be placed, but work on different input data according to the application: One approach assumes that previously defined rectangular items are to be placed freely on the(More)
Dr. Baltazar Leão Reis – Avenida Francisco Sales 1813 / 102 30150-221 Belo Horizonte MG Brasil. E-mail: baltazarleao@yahoo.com.br Meningiomas are tumors originating from meningothelial cells of the arachnoid membrane and are benign in most cases, corresponding to about 15% to 18% of all primary tumors of the central nervous system (CNS).

Necrotizing Fasciitis is a rapidly progressive, potentially fatal infection of superficial fasciae and subcutaneous tissue, usually resulting from an inciting trauma to the skin. Medical literature refers few cases of necrotizing fasciitis related to intra-articular infiltrations, that often lead to patients death. This report describes the clinical events(More)
We present an algorithm for computing a robust adaptive polygonal approximation of an implicit curve in the plane. The approximation is adapted to the geometry of the curve because the length of the edges varies with the curvature of the curve. Robustness is achieved by combining interval arithmetic and automatic differentiation.
INTRODUCTION Leptomeningeal carcinomatosis is a rare metastatic event in gynecological neoplasias, and most cases occur in ovarian cancer. It is extremely infrequent in cervical cancer, and so far, there are not any reports of this complication in association with endometrial cancer. PATIENTS AND METHODS We report a case of leptomeningeal carcinomatosis(More)
Adaptive documents undergo many transformations during their generation, including insertion and deletion of content. One major problem in this scenario is the preservation of the aesthetic qualities of the document during those transformations.As adaptive documents are instances of a template, the aesthetic quality of an instance with respect to the(More)

This paper presents an improved approach for automatically laying out content onto a document page, where the number and size of the items are unknown in advance. Our solution leverages earlier results from Oliveira (2008) wherein layouts are modeled by a guillotine partitioning of the page. The benefit of such method is its efficiency and ability to place(More)
Canine parvovirus (CPV) has been evolving, generating new genetic and antigenic variants throughout the world. This study was conducted to determine the types of CPV circulating in dogs in Figueira da Foz, Portugal. Thirty fecal samples, collected between 2006 and 2007 from dogs with clinical signs of CPV infection, were tested for CPV by a rapid,(More)
