Integrate and fire processes are fundamental mechanisms causing excitable and oscillatory behavior. Van der Pol [Philos. Mag. (7) 2 (11) (1926) 978] studied oscillations caused by these processes, which he called,relaxation oscillations' and pointed out their relevance, not only to…

Data from a network of experiments conducted during 1998 for 25 maize cultivars and 30 hybrids cultivated in 19 and 16 different environments, respectively, in the states of Piaui, Rio Grande do Norte, Pernambuco, Alagoas, Sergipe, and Bahia, Brazil, were…

This article proposes a method for achieving an appropriate balance between the parameters of support, precision, and simplicity during the evolution of classification rules by means of genetic programming. The method includes an adaptive procedure in order to achieve such…

The main contention in this paper is that the process of communicating scientific knowledge could be compared to the role of the translator as communicator (Hatim & Masón, 1997). Like the translator, the task of the scientist is to encode…

In big companies, managerial activities and organizational boundaries will over time hide most unevenly developed skill and knowledge distribution patterns; studying the organizations with the means of modern applied physics is thus quite difficult. People are forced to communicate along…

The Sami people have struggled for centuries to maintain their culture in spite of pressures against it from colonialism. The formal education systems of Norway and Finland have acted in discord with Sami decision-making since their inception. In response to…

Research in decision making has identified the importance of prior knowledge and heuristics on decision making behaviour. These develop with experience in a fashion similar to how domain experts develop specialized knowledge structures and heuristic reasoning patterns. This research is…
