Use of the Wavelet Transform for Digital Terrain Model Edge Detection (Special Issue—Wavelet Analysis)  [PDF]
Clovis Gaboardi
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.610171
Abstract: The purpose of this work is to analyze the feasibility of using the wavelet transform in the edge detection of digital terrain models (DTM) obtained by Laser Scanner. The Haar wavelet transform and the edge detection method called Wavelet Transform Modulus Maxima (WTMM), both implemented in Matlab language, were used. In order to validate and verify the efficiency of WTMM, the edge detection of the same DTM was performed by the Roberts, Sobel-Feldman and Canny methods, chosen due to the wide use in the scientific community in the area of Image Processing and Remote Sensing. The comparison of the results showed superior performance of WTMM in terms of processing time.
Preliminary studies of primary production in the Ubatuba region (Lat. 23o30'S - Long. 45o06'W), Brazil
Teixeira, Clovis;
Boletim do Instituto Oceanográfico , 1973, DOI: 10.1590/S0373-55241973000100003
Abstract: some data and observations of primary production and hydrographic parameters have been made in the region of ubatuba (lat. 23o30's long. 45o06'w) during two seasons: summer and winter. the primary production varied from 1.01 mgc/m3 /h to 28.16 mgc/m3 /h in summertime and from 0.24 mgc/m3 /h to 16.24 mgc/m3 /h in wintertime. the phytoplankton production is believed to be controlled primarily by the quantity of nutrient salts and there is a possibility that relatively nutrient-rich deeper cold waters may increase the fertility of the region.
Topological mass generation and duality transformations in diverse dimensions
Wotzasek, Clovis;
Brazilian Journal of Physics , 2004, DOI: 10.1590/S0103-97332004000200007
Abstract: in this seminar we shall discuss the issue of duality transformation in the context of f topological mass generation in diverse dimensions. particular emphasis will be given to the mass generation mechanism as the result of interference between self and anti self-dual components, as disclosed by the soldering formalism. since this is a gauge embedding procedure derived from an old algorithm of second-class constraint conversion used by the author to approach anomalous gauge theories, a quick review of the subject will be presented. the problem of classification of the electromagnetic duality groups that is closely related will also be briefly discussed. particular emphasis will be given to a new approach to duality based on the soldering embedding to tackle to problem of mass generation by topological mechanisms in d=3 and d=4 dimensions including the couplings to dynamical matter and nonlinear cases.

Introdu??o aos métodos para medir a produ??o primária do fitoplancton marinho
Teixeira, Clovis;
Brazilian Journal of Oceanography , 1973, DOI: 10.1590/S1679-87591973000100004
Abstract: in this review certain basic aspects of techniques established for primary productivity studies are presented. some emphasis has been given to a critical review of techniques mainly devoted to estuarine and coastal phytoplankton of tropical waters. the contents of this paper have been balanced along the lines of current research in marine primary production but only considering the basic methods needed to determine the primary production and standing-stock of phytoplankton. no attempt has been made to include some sophisticated methods, since the particular aim of the present manual is to become a useful guide for beginners in the field.
Situa??o do atendimento do paciente venéreo nas unidades sanitárias da Secretaria da Saúde do Estado de S?o Paulo, Brasil
Lombardi,Clovis;
Revista de Saúde Pública , 1978, DOI: 10.1590/S0034-89101978000100002
Abstract: the author describes the situation of venereal patients care in 340 health centers of the state of s. paulo (brazil) in 1975, through a questionnaire answered by those technically responsible (doctors) for the health centers. the questionnaire also included personal opinions, comments and suggestions. syphilis and gonorrhoeae are specifically studied in relation to incidence, laboratory diagnosis, therapeutic schemes, health education, as well as the relationship between the health center and other medical care agencies.
Situa??o da endemia da hanseníase no município de S?o Paulo, Brasil (1976-1977)
Lombardi,Clovis;
Revista de Saúde Pública , 1979, DOI: 10.1590/S0034-89101979000400004
Abstract: the situation of endemic hansen's disease in the county of s. paulo, brazil during 1976 and 1977 is described and analyzed and also characterized as a public health problem through the presentation and discussion of prevalence and incidence rates according to the location of the homes in the different districts and subdistricts of the city including the central, intermediary, and outlying zones of the citycounty. the specific medical resources available are described and evaluated according to the same criteria. an attempt was made to relate the distribution of the resources to the distribution of the endemic rates found.
Aspectos epidemiológicos da mortalidade entre doentes de hanseníase no Estado de S?o Paulo (1931-1980)
Lombardi,Clovis;
Revista de Saúde Pública , 1984, DOI: 10.1590/S0034-89101984000200003
Abstract: the study comprehends the patients (n=27,260) of hansen's disease (leprosy) deceased in the state of s. paulo, brazil, from 1931 to 1980. the author studies the time factor as related to some epidemiological characteristics connected with personal aspects such as patient's age and sex, final clinical form of the disease, place of death, time lag between the occurrence of disease and diagnosis, and time span between the occurrence of dissease and death. the time factor as related to the specific mortality and lethality coefficients in hansen's disease is analyzed by comparison with the proportional mortality data in the state of s. paulo, with regard to the above mentioned period. time-related trends in the profile of causes of death among the patients under consideration is also presented. causes of death are classified according to all the sections of the manual of the international statistical classification of diseases, injuries and causes of death (ninth revision-1975) and also according to some of its categories and sub-categories classically known as relevant to the pathology of hansen's disease. in the sub-group containing patients who died from hansen's disease, the distribution in time of some important personal characteristics such as age, final clinical form of disease, time span between the occurrence of disease and diagnosis, and time span since the beginning of disease till the patient's death are studied. the results found in this sub-group were compared to the ones found in relation to the universe of this study. the results obtained basically show: a) there is a tendency towards the improvement of public health patterns in the group studied, parallel to that observed for the state of s. paulo as a whole, but this tendency is influenced by specific factors, such as sulphonic therapy; b) the existence of two clearly distinct phases in the trends, of the specific mortality curves: i. e., before and after 1950; c) the low socio-economic status of the gr
EM TORNO à "BOA CIêNCIA": DEBATES JURíDICOS E A QUEST O PENITENCIáRIA NA IMPRENSA CURITIBANA (1901-1909)

Revista de História Regional , 2007,
Abstract: A inten o do artigo é discutir o problema penitenciário e como ele foi debatido na imprensa curitibana nos primeiros anos do século XX. Num primeiro momento, ana i sa alguns dos discursos acerca da criminalidade em Curitiba. Em seguida, e sem perder de vista aquelas reflex es, tenta mostrar como, a partir delas, surgem nas páginas dos jornais outros discursos, que apontam a urgência de uma institui o capaz de assegurar o seqüestro, do convívio social, dos indivíduos considerados perigosos. Mais que apontar a necessidade da cria o da penitenciária, no entanto, os juristas utilizam as páginas dos jornais para discorrer acerca do melhor modelo a ser adotado para assegurar, n o tanto o castigo, mas a regenera o física e moral dos crimi- nosos. Perpassando o trabalho, o objetivo de estabelecer a coerência entre o que se pensava em Curitiba e algumas das reflex es de ponta no debate criminológico internacio- nal do período. The objective of the present article is to discuss the penitentiary problem and how the press in Curitiba has presented it, during the first years of the Twentieth Century. Initially, there is an analysis of the speech used by the press to deal with criminality as a whole in the city. Then, this analysis is followed by an attempt to show how those considerations were the basis for the development of another speech, pointing to the necessity of an institution capable to provide the removal and imprisonment of the individuals deemed dangerous to society. More than the simple necessity for a penitentiary system though, lawmen of the period use the newspapers as a tribune to deliver a concept for the best model to be adopted regarding not so much as punish- ment but indeed physical and moral regeneration of the criminals. Throughout the text, the objective is also to per- ceive the similarity of views between what was thought in Curitiba and the frontline criminological thinking of the period.
Origens de uma política urbano-ambiental
Clovis Ultramari
Desenvolvimento e Meio Ambiente , 2001,
Abstract: This article discusses the increasing responsibilities to be fulfilled by the city management in finding solutions to social and environmental problems. On one side, cities are the locus of international loans programmes that oblige national governments to adopt structural adjustments; on the other, cities are obliged to rescue their population from social crises. At the same time, these cities, lacking national reference in terms of a country urban policy, adopt international models, some progressist, some very traditional. Sources for these policies are now diverse. In order to illustrate some ideas, the article presents examples of statements made by scientists and city managers representing institutions that formulate and foster policies at international level.
