In this paper we describe a numerical method to solve numerically the weakly dispersive fully nonlinear Serre–Green–Naghdi (SGN) celebrated model. Namely, our scheme is based on reliable finite volume methods, proven to be very efficient for the hyperbolic part of equations. The particularity of our study is that we develop an adaptive numerical model using moving grids. Moreover, we use a spec...

Desmoplastic fibroma (DF) is a very rare bone tumor, classified as a benign lesion. It might be locally a very aggressive tumor with a high rate of recurrence after surgical resection. We present a case of a 3-year and 6 month-old patient, with mandibular desmoplastic fibroma. The clinical, imaging, histological findings and surgical treatment are discussed and, also, a brief review of the lite...

All knowledge belongs to narrative knowledge, and also local knowledge. Post-modernism can be defined as “elimination of grand narrative”, so in the world of post-modernism, validity of knowledge has become an issue. Local knowledge emphasizes that generation and justification of knowledge has its local features, so it has no way to surpass the dilemma of cultural relativism. Theoretically, in ...

However, the particularity of the alimentary track restricts the utilization of the current available examine techniques. The upper gastrointestinal tract can be examined by Gastroscopy. The bottom 2 meters makes up the colon and rectum, and can be examined by Colonoscopy. In between, lays the rest of the digestive tract, which is the small intestine characterised by being very long (average 7 ...

The paper presents a control strategy for a hyper redundant micromanipulator that has the particularity to have either a) binary joints: only a small finite number of position are allowed within min and max bounds and b) continuous joints: the joint can move continuously within its min and max bounds. The problem optimization is double: a)solve inverse kinematics for this kind of system and b) ...

This paper presents an ontology-based approach for the dynamic generation of learning knowledge objects (LKO). These objects have the particularity of implementing AIED techniques and they exhibit characteristics hitherto reserved for intelligent tutoring systems (ITS): they are knowledgebased, adapted to a learner model and they are composed dynamically according to a learning need and a parti...

Effective sparse representation of X-ray medical images within the context of data reduction is considered. The proposed framework is shown to render an enormous reduction in the cardinality of the data set required to represent this class of images at very good quality. The goal is achieved by (1) creating a dictionary of suitable elements for the image decomposition in the wavelet domain and ...

This paper addresses the problem of automatically extracting the author from heterogeneous HTML resources as a sub problem of automatic metadata extraction from (Web) documents. We take a supervised machine learning approach to address the problem using a C4.5 Decision Tree algorithm. The particularity of our approach is that it focuses on both, structure and contextual information. A semi-auto...

Retrieving useful information from video sequences, such as the dynamics of pedestrians, and other moving objects on a video sequence, leads to further knowledge of what is happening on a scene. In this paper, a Target Framework associates each person with an autonomous entity, modeling its trajectory and speed by using a state machine. The particularity of our methodology is the use of a Movem...

This paper describes the objectives, the tasks proposed to the participants and the associated protocols in terms of database and assessment tools of two present competitions on fingerprints and on-line signatures, the results of which will be ready for presentation at the next ICB conference. The particularity of the fingerprint competition is to be an on-line competition, for evaluation of fi...
