This paper depicts adaptation of expert systems technology using fuzzy logic to handle qualitative and uncertain facts in the decision making process. Human behaviors are mostly based upon qualitative facts, which cannot be numerically measured and hardly to decide correctly. This approach is an attempt to cope with such problems in the scenario of teachers’ performance evaluation. An Expert Sy...

This study uses quantitative method to examine whether or not a social constructivist theory-driven pedagogical model integrated with weblogs is associated with improved critical thinking skills. Forty secondary two students at the age of 13 completed a series of extra-curricular activities designed according to a proposed model within ten months. Half of these students came from high ability c...

A Biometric expert, or an expert in biometric recognition context, refers to a method that expresses an opinion on the likelihood of an identity by analyzing a signal that it is specialized on, e.g. a fingerprint expert using minutiae, a lip-motion expert using statistics of optical-flow. Accordingly, there can be several experts associated with the same sensor data, each analyzing the data in ...

Qualitative reasoning has been successfully used for ecological modelling, particularly when numerical data are not available. However, in order to further explore the potential of this modelling approach, it is important to discuss how to incorporate numerical data, if available, and to develop means to evaluate conceptual aspects and model outputs. This paper describes a study on qualitative ...

In this paper, we present an unsupervised method for determining the polarity of opinions. It uses a word sense disambiguation algorithm to determine the correct sense of the words in the opinion. The method is also based on SentiWordNet and General Inquirer to determine the polarity of the senses. Due to the characteristics of these external resources, the proposed method does not depend on th...

Nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. Copper oxide nano materials are of interest on account of their potential uses in many technological fields. In this study  CuO nanoparticles were synthesized via simple sol gel method using basic CuSO4<...

According to the qualitative safety evaluation index system of electric power communication network, it is easy to occur in the scoring problems, we put forward a kind of expert evaluation data by correlation degree, solve the problem of qualitative index difference. The method based on Relative Grey Relational Analysis on safety evaluation data, the establishment of expert evaluation of the re...
