In the present paper we propose a consistent way to integrate syntactical least general generalizations lgg s with semantic evaluation of the hypotheses For this purpose we use two di erent relations on the hypothesis space a constructive one used to generate lgg s and a semantic one giving the coverage based evaluation of the lgg These two relations jointly implement a semantic distance measur...

AbstractTeacher students who have taken the micro-teaching course are expected to master eight essential teaching competencies, namely: 1) opening and closing learning skills, 2) explaining 3) questioning skills (basic, advanced), 4) variation 5) reinforcement 6) class management 7) small group individual 8) lead discussions. YouTube-based microteaching-learning is help competencies even in onl...

We systematically analyze audio key finding to determine factors important to system design, and the selection and evaluation of solutions. First, we present a basic system, fuzzy analysis spiral array center of effect generator algorithm, with three key determination policies: nearest-neighbor (NN), relative distance (RD), and average distance (AD). AD achieved a 79% accuracy rate in an evalua...

E-learning and Web-based training have evolved over time from a newborn trend for complementing the learning process to a major form of education and training for supporting mainly geographically scattered users. The basic aim of this chapter is the description of a platform for open and distance training, which is mainly focused at supporting the needs of Vocational Training Centers as well as...

Alignment algorithms are powerful tools for searching for homologous proteins in databases, providing a score for each sequence present in the database. It has been well known for 20 years that the shape of the score distribution looks like an extreme value distribution. The extremely large number of times biologists face this class of distributions raises the question of the evolutionary origi...

Auditory distance perception plays a major role in spatial awareness, enabling location of objects and avoidance of obstacles in the environment. However, it remains under-researched relative to studies of the directional aspect of sound localization. This review focuses on the following four aspects of auditory distance perception: cue processing, development, consequences of visual and audito...

The factors influencing dam safety are complex and their impact on dam safety is fuzzy and uncertain. With the introduction of the Dempster-Shafer theory, BP neural network and Jousselme distance function into dam safety monitoring, a new method for dam safety evaluation is explored. Firstly, the basic probability assignment of the factors influencing dam safety is determined by BP neural netwo...

The goal of this paper is a comprehensive analysis of basic reasoning patterns that are characteristic of vague predicates. The analysis leads to rigorous reconstructions of the phenomena within formal systems. Two basic features are dealt with. One is tolerance: the insensitivity of predicates to small changes in the objects of predication (a one-increment of a walking distance is a walking di...

Basic education has been listed as a priority of development efforts in poor regions around the world [1]. Distance learning has significant potential for enhancing basic education, and the benefits of information and computer technology can provide an efficient means for deploying a distance learning system. Such a system, dubbed the “Digital StudyHall,” is proposed by Wang, et. al. for deploy...

Ad-hoc On-demand Distance Vector (AODV) provides scalable and effective solution for packet routing in mobile wireless ad hoc networks, however, the path generated by this protocol may derivate far from optimal because of inconsideration of node power ,load unbalance and link state,resulting in energy consumption of each nods is imbalanced and reduce the lifetime of whole networks. Based on the...
