    An adaptive learning algorithm for supervised neural network with contour preserving Classification 

    Piyabute Fuangkhon; Thitipong Tanprasert (2009-11)

    A study of noise tolerance characteristics of an adaptive learning algorithm for supervised neural network is presented in this paper. The algorithm allows the existing knowledge to age out in slow rate as a supervised neural network is gradually retrained with consecutive sets of new samples, resembling the change of application locality under a consistent environment. The algorithm utilizes the contour preserving classification algorithm to pre-process the training data to improve the classification and the noise tolerance. The experimental ...

    Applying six sigma for quality assessment in a eLearning courseware production process 

    Nagi, Kuldeep (2010-05)

    Six Sigma method claims that focusing on reduction of variation will lead to reduction in defects in a business product. Its prestige and value is well known within the manufacturing industry. However, it is seldom applied to educational products such as courseware produced and used in higher education. It is beginning to be recognized as key process for quality assessment in eLearning and eTraining sectors in ASEAN. A consistent high quality in an eLearning or eTraining product can be achieved by applying Six Sigma in the courseware production ...

    Attitudes toward using communication technologies in education: a comparative study of email and SMS 

    Boonlert Watjatrakul (2009-12)

    Educational institutions deploy email and short message service (SMS) to maintain efficient communication with their students. This research examines factors influencing students' attitudes toward using SMS and email, and compares the differences in the proposed factors between email and SMS. The results show that information richness and mobility affect students' perceived utility of email and SMS while information privacy and perceived utility affect the students' attitudes toward using email and SMS. Social pressure has found no impact on ...

    Brain Circulation: the Issue of Brain Drain and Brain Gain 

    Nathara Mhunpiew; Mark Kolenberg (SPR Academic Forum, 2016-08)

    Nowadays in our modern society, globalization and advanced technology have led to new ways of learning. Until the end of the 20th century, learning occurred particularly through traditional way of learning such as in-class education. Students or learners did not have the choice in the way of learning – in-class or online – they had to go to class and learn in the classroom with teachers and other students. Since the end of the 20th century and the beginning of the 21st century new ways of learning have emerged: it is now possible in nowadays ...

    Clustering approach to examination scheduling 

    To, Tang Van; Win, Soe San (2010-05)

    The difficulty in examination scheduling is to draw an examination timetable by taking a number of different constraints into account. This paper attempts to optimize two major constraints-to minimize the examination time conflicts and the number of consecutive examinations for a student in a day. Clustering method is applied by analyzing exam enrollments and then groups students into clusters so that students within a cluster are having more similar subject combination to each others than those in another clusters. The purpose of clustering ...

    Co-existance between AC-distribution and DC-distribution: in the view of appliances 

    Kittiphan Techakittiroj; Virach Wongpaibool (2009)

    This work demonstrates the possibility of using the available-in-market appliances in a DC-distribution system. This demonstration also represents an alternative migration from AC-distribution to DC-distribution. DC-distribution has been shown to be more efficient and provided good power quality in a distribution system. The power supply technology in the modern appliances makes the possibility of an appliance to be used in either both AC-distribution and DC-distribution without any modification. Appliances are tested by using an AC-source ...

    Creatinine prediction from body composition: a neural network approach 

    Thitipong Tanprasert; Chularat Tanprasert (2009-12)

    Creatinine, a naturally-produced chemical compound in blood, has been commonly used as a reliable indicator of kidney function. Creatinine level is typically obtained from blood-test. In this paper, a technique for predicting the criticality of creatinine level in blood is presented. The proposed technique takes only body size and mass parameters obtained from advanced weighing scale and body scanner, allowing the prediction to be done more casually. The technique applies a multi-layered feed-forward neural network for developing the prediction ...

    Cross-disciplinary research and education post Copenhagen 2009 

    Nicholls, Philip (2010)

    The study of the environment and environmentalism in our universities too often fails to recognize its inherently trans-disciplinary nature. As we all know, beyond academia, environmental issues simultaneously encompass corporate, political, social, scientific, engineering, health, cultural, biological, legal and economic factors. This long list can indeed be readily expanded. Yet, in practice, if addressed at all, the issues of environmental research and education tend to be departmentalized; an outcome of what may be characterized as an ...

    Detection of Orcinol-O-methyl transferase enzyme encoding gene in East Asian rose Rosa multiflora 

    Viyada Kunathigan (2014)

    3,5-dimethoxytoluene (DMT) is a key component of “tea scent” in Chinese rose (Rosa chinesis) and a hybrid of Chinese rose (Rosa X hybrida). DMT biosynthesis is catalysed by enzymes Orcinol O-methyltransferase (OOMT) 1 and 2 (Rosa chinesis and Rosa X hybrida) and OOMT like (Rosa chinesis Xing-xing-hei). The East Asian rose Rosa multiflora may also contain OOMT gene. The presence of OOMT gene in this rose could be a potential useful resource for Asian fragrance industry. This project aimed to detect the OOMT encoding gene in this rose variety. Rosa ...
