Abstract In this commentary, I reflect on the relevant role that education of teachers imply to assure a successful teaching probability at school levels. Unfortunately, research issue is still scarce. sense, four papers included in section are welcome because they approach problem from different perspectives. analyse these perspectives using Didactic-Mathematics Knowledge and Competences Model...

The proposed integration architecture aims at exploiting data semantics in order to provide a coherent and meaningful (with respect to a given conceptual model) view of the integrated heterogeneous information sources. The architecture is split into five separate layers to assure modularization, providing description, requirements, and interfaces for each. It favors the lazy retrieval paradigm ...

In this paper, we propose a modification to the existing Data Encryption Standard (DES) to make it secure and prone to the bit errors caused by the wireless channel. We observe that using the modified algorithm in wireless channels, improves the bit error rate (BER) performance as well as security compared to DES. Wireless channels are an open medium to intruders and their attacks; encryption i...

To assure the maximal energy yield of grid connected PV systems, system faults have to be identified as quickly as possible. For this task several procedures that offer an almost continuous performance check are in development or application. One of them is the EU-funded project PVSat2. In the framework of this project, a model, able to reflect the efficiency characteristics η(G,T) at MPP of bo...

abstract Real-time artiicial intelligent systems are required to respond within a given deadline or to assure an optimal response time. Despite the success of anytime algorithm and approximate processing, more work is still needed, especially in order to address properly the guarantee response time problem. This paper presents a model, called GREAT Mouad-dib 92b], which combines progressive rea...

A model predictive control architecture based on discrete time nonlinear car model is derived to solve regulation(“parking”) problem. Parameters of the proposed controller are chosen by considering terminal state constraints. This setup combined with terminal state penalty in the cost function could assure control stability. The generated trajectory satisfies minimum curvature requirements and ...

Service-oriented architectures and web services have been widely adopted by companies to pervade integration among software systems. As reliable services are essential to assure that these systems work correctly, formal and systematic testing should be performed. This document reports the application of a model-based approach to test web services in the context of real-world applications of an ...

With globalization, more and more companies are becoming multisited. Efficient and timely collaboration and communication among the development team members become critical for product success. This paper proposes a web-based virtual environment for mobile phone customization, named VMPDS (Virtual Mobile Phone Design Space). The features of this system include the combination of web technology ...
