This calculation is based on calculation of torque components of induction machines. Basic torque components are expanded, using knowledge of machine’s geometry, to the periphery of machine’s rotor. Using Fourier analysis of torque components it is possible to calculate forces…

For the expansion of PLC systems, it is necesssary to have a detailed knowledge of the PLC transmission channel properties. This contribution shortly discusses characteristics of the PLC environment and a classification of PLC transmission channels. A main part is…

This article takes down the knowledge with determination of criteria weights in the terms of computer software of superconductive materials. This software relieves processing of considerable enters data. The criteria of the weights were determinated by Fuller triangle and Saaty´s…

This article offers a critical synthesis of the knowledge obtained in the wake of the work of the Comite d’experts sur l’apprentissage de l’écriture (Committee of experts on learning to write), which published a report entitled, « Mieux soutenir le…

Using the underlying idea of the current-mode control, a new dynamical, sliding-mode control for the boost dc-dc converter is proposed. Such controller is easy to design, robust under load and input voltage variations, exhibits fast response, does not depend on…

Can children genuinely create new knowledge, as opposed to merely carrying out activities that resemble those of mature scientists and innovators? The answer is yes, provided the comparison is not to works of genius but to standards that prevail in…

The Knowledge Society Network (KSN) “takes advantage of new knowledge media to maximize and democratize society’s knowledge-creating capacity” (www.ikit.org/KSN). This article synthesizes the principles and designs of this network which were initiated over 15 years ago, and presents an exploratory…

Three classrooms of Grade 4 students from different schools and diverse backgrounds collaborated in early algebra research to solve a series of linear and quadratic generalizing problems. Results revealed that high- and low-achieving students were able to solve problems of…

Gilbert Ryle (1949) divided knowledge into “know that” and “know how”, which is neatly appealing to many design and technology educators, and like many writers on developing the curriculum, Kahney (1993) made a distinction between declarative knowledge:

verbal knowledge,…

Knowledge Building as a theoretical, pedagogical, and technological innovation focuses on the 21st century need to work creatively with knowledge. The team now advancing Knowledge Building spans multiple disciplines, sectors, and cultural contexts. Several teacher-researcher-government partnerships have formed to bring…
