In E-learning systems, where both helpers (tutors) and learners are separated geographically, finding a reliable helper is one of the most important challenges. Although helpers could have a lot of useful information about courses to be taught, many learners fail to understand their presentations. A major part of this paper deals with the following challenges: do helpers have information that t...

Effective operators relevant for generating small Majorana masses for the neutrinos in the Standard Model will be considered. These operators serve as a useful guide for building models of neutrino mass. Some of these operators are represented by familiar models in the literature, and others lead to interesting new models. The number of the relevant operators will be drastically reduced if neut...

This paper presents a model to diagnose maturity and capabilities of Public Agencies (PAs) in pursuing the open data principles and practices. The open data maturity model, called OD-MM, was piloted in ten PAs from three Latin American countries, validating in this way the web tool that operationalizes the model. This web tool is a valuable diagnostic tool for PA's, since it shows all weaknesse...

As modern systems become more complex, design approaches model different aspects of the system separately. When considering (intra and inter) system interactions, it is usual to model individual scenarios using UML’s sequence diagrams. Given a set of scenarios we then need to check whether these are consistent and can be combined for a better understanding of the overall behaviour. This paper a...

Post-evaluation analysis of the model of a constrained optimization problem is conducted after obtaining preliminary optimal or heuristically good solutions. The primary goal of post-evaluation analysis is to reconsider assumptions made in the model in the light of information generated while finding the good solutions as well as information not previously detailed in the model. We seek extensi...

This paper is an introduction to the framework for the deadlock analysis of object-oriented languages we have defined in [6, 5]. We present a basic Java-like language and the deadlock analysis model in an accessible way. We also overview the algorithm for deciding deadlockfreeness by discussing a number of paradigmatic examples. We finally explore the techniques for coping with extensions of th...

UNLABELLED Knowledge of the anatomy and physiology of the semicircular canals and their central pathways is essential for the diagnosis of vestibular pathology. This 3 dimensional (3D) scheme of the Semicircular Canals (SSCC) is a teaching tool and a useful reference guide for rapid consultation. MATERIAL AND METHODS A multicolored cardboard model is accompanied by a user manual which provide...
