The aim of our research is developing educational software to assist teachinglearning process from elementary schools to college. We argue that all educational environments have to concern about pedagogical aspects in order to guarantee better quality for students and teachers activities during the educational process support by educational software. To achieve this we must to observe some guid...

This paper argues that design and usability issues are of great importance on technology-based implementation and evaluation programs, as they can have both a positive and a negative impact on teaching-learning processes. For instance, the quality of the design can aid the development of new reasoning skills on the one hand, and on the other it can affect the understanding of physical phenomena...

Dear friend. You are almost ready to close this volume and put it on a shelf or return it to the College Bookstore, or... Please do not hurry to make your final decision. I hope that this volume was your partner during a semester of challenging Physics. It was designed to help you make your notes during the lectures, which I hope you enjoyed very much. I am sure that this book helped you a grea...

Aiming at the characteristics of high dimension and small samples in microarray data, this paper proposes a selective ensemble method to classify microarray data. Firstly, kruskal-wallis test is used to filter irrelevant genes with classification task and to obtain a set of genes, and then a reduced training set is produced from original training set according to gene subset obtained. Secondly,...

We intend to carry out this work, to contribute for an increased knowledge about the history of science and chestnut as well as identifying the contribution of Amato Lusitano in therapeutic use of Chestnut. The chestnut has been around for thousands of years helping the man since the Paleolithic. This species was introduced in Europe during the Roman era, due to its potential, representing in o...

A major factor to be considered in the study of teaching-learning process based on spoken communication is sound field. Excessive background noise levels or reverberation time values inside a classroom interfere with oral communication, creating an acoustic barrier to the teachinglearning process. In previous work, reverberation time was measured in a sample of university classrooms in the City...

– In this article, Teaching-learning opposition based optimization (TLOBO) algorithm based on the natural phenomenon of teaching and learning is applied to design an optimal higher order stable low pass (LP) and high pass (HP) IIR digital filter using different design criterion. The original TeachingLearning Based Optimization (TLBO) algorithm has been remodeled by merging the concept of opposi...

This study presents a hybrid metaheuristic algorithm to obtain optimum designs for steel space buildings. The optimum design problem of three-dimensional steel frames is mathematically formulated according to provisions of LRFD-AISC (Load and Resistance factor design of American Institute of Steel Construction). Design constraints such as the strength requirements of structural members, the dis...
