We propose a new learning algorithm for multi Multi Layered Perceptron (MLP) architecture useful for complex classification. First, on the principle “divide and conquer”, a quantization is performed on the input space. One classical Neural Network (NN) is devoted to each subregion that results from this quantization. A cooperative learning procedure allows to train the NNs in such a way that NN...

As the speed increase of single-core processors keeps declining, it is important to adapt simulation software to take advantage of multi-core technology. There is a great need for simulating large-scale systems with good performance. This makes it possible to investigate how different parts of a system work together, without the need for expensive physical prototypes. For this to be useful, how...

BACKGROUND Nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. This study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. METHODS Fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. Objectiv...

In this article we propose a robust facial analysis of multiple camera system for cyber games which is capable of extracting the facial features of a face making large lateral movements. Tactical maneuvers of the gamer make single camera acquisition system unsuitable to analyse and track the face due to his large lateral movements. Although our proposition of double camera acquisition system re...

conclusion safety-related parameters of posterolateral and posterior approaches in supine thoracentesis are far better than that of the conventional lateral approach. background in patients who have difficulty sitting, thoracentesis is attempted in a supine position via lateral approach. recently, a new table has been designed for supine thoracentesis. this table has gaps that allow access to t...

background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...

The emerging paradigm of grid computing provides a powerful platform for the solution of complex and computationally expensive problems. An example of this is the multi-objective evolutionary design of robust controllers, where each candidate controller design has to be synthesised and the resulting performance of the compensated system evaluated by computer simulation. This paper introduces a ...

systems thinking is not a new concept to health system strengthening; however, one question remains unanswered: how policy-makers, system designers and consultants with a system thinking philosophy should act (have acted) as potential change agents in actually gaining opportunities to introduce systems thinking? development of comprehensive multi-year plans (cmyps) for immunization system is on...
