One of the most common uses of classified satellite images is mapping land cover alterations via change detection. If images for two different dates are not available from the same sensor, one has to use two sensors with different resolutions, and images or maps must be either upscaled or downscaled. We present a study based on two landcover maps produced for the agglomeration of Geneva, Switze...
Our aim is to present a case with initial diagnosis of non-classified type duodenal atresia operated in our clinic. A patient with prenatally suspected to be duodenal atresia was explored. At laparotomy type 3 duodenal atresia was found between 2nd and 3rd parts of duodenum. In addition, a web was detected distal to the atresic part. Duodenoduodenostomy together with web excision was performed....
541 regard to the anoxic, toxemic, and neurogenic factors involved in shock, without arbitrarily resolving justifiable differences of opinion about these factors as they are conceived by the investigators whose works he cites. Somewhat neglected by understatement, however, are the evidences of Eversole, Swingle, Wang, and others on the role of the nervous system in the dynamic evolution of shoc...
OBJECTIVES There are some common occupational agents and exposure circumstances for which evidence of carcinogenicity is substantial but not yet conclusive for humans. Our objectives were to identify research gaps and needs for 20 agents prioritized for review based on evidence of widespread human exposures and potential carcinogenicity in animals or humans. DATA SOURCES For each chemical age...
INTRODUCTION Recently, researchers have been considering as adverse prognostic factors in primary glioblastomas not only clinical indicators but also various cellular, genetic and immunological markers. The aim of the present article was to report a case of primary glioblastoma multiforme with poor survival in a patient after surgical intervention, and to determine the unfavorable prognostic ma...
The financial market dynamics can be characterized by macro-economic, micro-financial and market risk indicators, used as leading indicators by market professionals. In this article, we propose a method to identify market states integrating two classification algorithms: a Robust Kohonen Self-Organising Maps one and a CART one. After studying the market’s states separation using the former, we ...
This paper examines the use of the postulational approach to facet analysis to manually induce a faceted classification ontology from a folksonomy. An in-depth study of faceted classification theory is used to form a methodology based on the postulational approach, which is then used to facet analyze a dataset consisting of over 107,000 instances of 1,275 unique tags representing 76 popular non...
Fractal coding and classi ed transform coding exhibit strong structural similarity, but they use di erent types of redundancy in image data: piecewise self-similarity in one case and local correlation in the other. Comparing performance of the two techniques leads to a quantitative, compression-oriented de nition of piecewise self-similarity. The amount of piecewise self-similarity is evaluated...
Nonlinear predictive split vector quantization (NPSVQ) and classiied NPSVQ (CNPSVQ) are introduced to exploit the correlation among the speech spectral parameters from two adjacent analysis frames. By interleaving intraframe SVQ with forward predictive SVQ, error propagation is limited to at most one adjacent frame. At an overall bit rate of about 21 bits/frame, NPSVQ can provide similar coding...
Fractal coding of digital images o ers many promising qualities. The encoding process, however, su ers from the long search time of the domain block pool. A standard technique for speeding up the encoding is the feature classi cation of blocks. In this paper we show that the classes can be arranged in a tree, and searched by a pruning algorithm developed and explained in a previous paper by the...
