Previous research has shown that numerical magnitude knowledge is related to current mathematic abilities and predictive of future mathematics performance. Much of this early research examined magnitude knowledge of positive whole numbers, more recently this has been extended to positive rational numbers. However, research about negative number magnitude knowledge is less abundant. The present ...

This paper introduces a new method to model the permanent magnet synchronous machines (PMSMs) with saliencies due to the salient structure and magnetic saturation. Two parameters are defined to indicate these saliencies, i.e. the structural saliency ratio (Kstr) and the saturation saliency ratio (Ksat). To verify the nonlinear model, a real PMSM is tested and numerically simulated. The nonlinea...

1 The most challenging problem of J2EE application deployment is to determine which components should be deployed onto which servers in terms of non-functional properties. This paper proposes an empirical approach with some mathematic enhancement. It does two contributions to J2EE application deployment: 1) patterns are adopted to specify why, when, where and how to deploy so that the empirical...

Mathematic connection is one of the basic abilities someone must have in order to learn mathematic successfully. helps understand function mathematics, improving concept, determining correlation among concepts, and identifying application surrounding environment. The most common issue occur regarding this case that ability pedagogy students are considerably low finally result learning outcome. ...

Previous works on evaluating the performance of Question Answering (QA) systems are focused on the evaluation of the precision. In this paper, we developed a mathematic procedure in order to explore new evaluation measures in QA systems considering the answer time. Also, we carried out an exercise for the evaluation of QA systems within a time constraint in the CLEF-2006 campaign, using the pro...

In this paper we investigate in detail the properties of a dynamic resource allocation scheme that utilizes online measurements to optimally adjust scheduling weights and to achieve the required QoS, under a given pricing structure. Extending our previous work, we consider here an additional important QoS parameter, namely, the average queueing delay, in order to provision favorable QoS guarant...

Previous works on evaluating the performance of Question Answering (QA) systems are focused in the evaluation of the precision. Nevertheless, the importance of the answer time never has been evaluated. In this paper, we developed a mathematic procedure in order to explore new evaluation measures in QA systems considering the answer time. Also, we carried out an exercise for the evaluation of QA...

The mathematic models for thermal, and PV solar power inserted in the ESP-r, which is the integrating building energy and environment simulation tool, were verified with the measured da ta. Using the verified model, the energy performance of an office building, equipped toward the south with conventional absorptive single facade or unventilated double PV facade or outward ventilated double PV f...

Both pros and cons of calculus reform have been widely discussed since late 1980’s. In spite of arguments are poles apart, calculus reform is still discussed worldwide. The students of Taiwanese university of technology usually have a high failure rate in calculus, thereby affecting the performance of advanced application courses. Through calculus curriculum development of this study, students ...
