The problem of optimization will be addressed in this article, based on the premise that the successful implementation of Big Data solutions requires as a determining factor not only effective -it is assumedbut the efficiency of the responsiveness of management information get the best value offered by the digital and technological environment for gaining knowledge. In adopting Big Data strateg...

Currently, the critical communications sector is aware of the need for evolving the portfolio of service capabilities to support advanced multimedia communications in their daily emergency operations. However, there is a discussion about the convenience of evolving the private communication networks or adopting commercial network technologies, which have evolved significantly during the last ye...

This paper analyses the pattern and rate of adoption of mobile telephones by the Portuguese population. It is shown that the pattern of diffusion is S-shaped and is consistent with a logistic function, which describes a symmetrical growth process. Furthermore, it is found that about 67 percent of the population will likely adopt mobile phones, and that the levelling-off process in the diffusion...

Many manufacturing organisations while doing business either directly or indirectly with other industrial sectors often encounter interoperability problems amongst software systems. This increases the business cost and reduces the efficiency. Research communities are exploring ways to reduce this cost.

Self-organizing maps are widely used in visual data mining. This paper proposes a new visualization approach for GHSOM algorithm, a hierarchical variant of SOM. The method is based on pie charts. That improves the visualization in hierarchical data structures making possible to extract all the existing relationships among the attributes of the neurons at any hierarchy level. The methodology is ...
