We propose an innovative segmentation algorithm based on mathematical morphology operators. This definition is based on a morphological and fuzzy pattern-matching approach, and consists in comparing an object to a fuzzy landscape representing the degree of satisfaction of an affinity relationship. It has good formal properties, it is flexible, it fits the intuition, and it can be used for struc...

In order to cope with the ambiguity of spatial relative position concepts, we propose a new definition of the relative position between two objects in a fuzzy set framework. This definition is based on a morphological and fuzzy pattern-matching approach, and consists of comparing an object to a fuzzy landscape representing the degree of satisfaction of a directional relationship to a reference ...

I propose a modern OO language update of the Parameterized Factory Creational Pattern [Gamma95]. It is compact since it folds the Factory method into an abstract base class, and imposes a package structure on its concrete subclasses. The design is demonstrated in Java, but is also applicable to C# and other modern object-oriented languages.

In this paper we present the Reactor Pattern to enable the modelling of processes that consume inputs and produce outputs under specific environmental conditions and on being triggered by certain events. Reactor pattern is a content ontology design pattern and is especially targeted towards modelling reactive processes with a “black box” view of the process.

The problem domain of a design pattern describes the problem context in which the pattern can be applied. In general, determining the applicability of a pattern to a particular problem heavily relies on the knowledge and experience the developer has with the pattern. This significantly limits the use of patterns. To address this issue, we propose an approach for rigorously specifying the proble...

awareness of hyperdontia pattern/prevalence can be useful in early diagnosis and prevention by general practitioners, pediatric dentists, and orthodontists. since the previous results regarding the pattern of hyperdontia (supernumerary teeth) are controversial, this study aimed to assess this subject among iranian orthodontic patients.all approved panoramic radiographs of 3374 orthodontic patie...

in the present study, the usage pattern of anti-inflammatory drugs-steroidal and non-steroidal- in patients referred to 13 aban pharmacy in sari was evaluated. the results show a high rate of anti-inflammatory drug prescriptions, mainly by general practitioners with ibuprofen, diclofenac and mefenamic acid being the most widely used nsaids and prednisolone, dexamethasone and betamethasone being...

background bloodstream infection (bsi) is an important cause of mortality and morbidity and among the most common health-care associated infections. in this study we described the frequency of occurrence and antimicrobial susceptibility patterns of nosocomial and community-acquired bsi isolates from a teaching hospital in tehran, iran. patients and methods this cross-sectional study was conduct...
