PURPOSE Several MRA techniques have been implemented for non-invasive imaging of the portal vein. A time-spatial labeling inversion pulse (time-SLIP) technique was reported using a free hand spatial selection and tag-on and tag-off alternating scan and MIP processing to only depict the marked blood while canceling the background signals at any specified inversion time [1]. The purpose of this s...

We study an inverse problem for the fractional Schr\"odinger equation (FSE) with a local perturbation by linear partial differential operator (PDO) of order smaller than Laplacian. show that one can uniquely recover coefficients PDO from Dirichlet-to-Neumann (DN) map associated to perturbed FSE. This is proved two classes coefficients: which belong certain spaces Sobolev multipliers and bounded...

In this paper, a two-stage fuzzy random programming for a management problem in terms of water resources allocation having fuzzy random variable coefficients and decision vector of random variables is studied. The first results show the fact that a fuzzy pseudorandom optimal solution of a two-stage fuzzy random programming may be resolved into a two of pseudorandom optimal solutions of relative...

A continuous evaluation of the stakeholder management process can be achieved using definitive key performance indicators (KPIs). An exhaustive literature survey in this direction provided a set 26 assessed through questionnaire for their possible implications on process. The was conducted among 55 respondents with experience building information modeling (BIM) mega-construction projects. data ...

We address the problem of developing a flexible framework for information retrieval (IR) in structured documents, such as XML. The framework is able to support a wide range of structured IR queries, transparent instantiations of different retrieval models, and different physical implementations. It is based on so-called score region algebra (SRA) that can express the following four essential ra...

In this paper, we introduce the concept of the generalized topological molecular lattices as a generalization of Wang's topological molecular lattices,  topological spaces, fuzzy topological spaces, L-fuzzy topological spaces and soft topological spaces. Topological molecular lattices were defined by closed elements, but in this new structure we present the concept of the open elements and defi...

BACKGROUND Conventional spin-echo (PD-CSE) and fast spin-echo (PD-FSE) techniques are frequently used to detect meniscal tears. However, the time delay for imaging with PD-CSE has resulted in its replacement with faster techniques, such as proton density fast spin-echo (PD-FSE), which has become a frequent tool at most diagnostic centres.Qualitative analysis shows that the PD-CSE technique is m...

In this paper we present the linear combination of a fuzzy opening and closing filter with locally adaptive structuring elements that can preserve the geometrical features of an image. Based on the adaptation algorithm of linear combination of the fuzzy opening and closing filter, the optimal structuring element for image representation is obtained. The optimal structuring element is an indicat...

In this paper a general bottleneck combinatorial optimization problem with uncertain element weights modeled by fuzzy intervals is considered. A possibilistic formalization of the problem and solution concepts in this setting, which lead to compute robust solutions under fuzzy weights are given. Some algorithms for finding a solution according to the introduced concepts and evaluating optimalit...

Conventional approach to mathematical description of experiments applies probability theory. Here, another approach is used to express uncertainty based on probability, fuzzy sets, and evidence theory. The paper presents a new reliability model of an element working in different environmental and stress conditions. Fuzzy and probability descriptions are combined together using evidence theory t...
