This study employs the Data Envelopment Analysis (DEA) technique, an efficiency model, to measure public schools in Thailand. Data came from 455 public upper secondary schools in Northern Thailand. The results reveal that the schools mostly operate inefficiently. To ascertain the efficiency measures, sensitivity analysis reveals the robustness of the resulting efficiency measures on efficiency. Policy...
In today’s ultra modern world the traditional face to face (F2F)teaching has been replace by e-learning or online learning .Companies find this method very effective to train their employees without using up work hours. E-learning has been implemented by many educational institutions at undergraduate and graduate level in the Gulf region. Blended learning has been adopted by many schools and universities...
In this paper, we present a scene change or shot boundary detection method based in the changes in entropy of differences between uncompressed video frames. As in the uncompressed domain, cues for scene or shot boundaries are not available, detecting video content features is a non-trivial and typically requires additional complexity in the evaluation. The entropy presents a metric for the complexity...
An experimental assessment of the impact of the electromagnetic environment of a 400 kV substation on the performance of ZigBee equipment is described. The experimental assessment includes a pragmatic field trial and a laboratory test. The laboratory test, in which all external noise and interference are excluded, is used as a control. A simple set of metrics are used to compare the performance of...
This paper presents an effort estimation model for the content management systems which can be used to estimate the effort required for designing and developing. The data from the different content management system projects are studied and the model is finalized by using the bagging predictor on linear regression learning model. These projects are categorized based on their size and total/build effort...
Traditional Gaussian Kernel is the most widely used in Kernel Machines, such as Support Vector Machines and has been extensively studied in the field of Neural Networks, such as Radial Basis Function Network. However, because of the same weight and data distribution defined in traditional Gaussian Kernel, the weights of Neural Network based on such kernels are controlled mostly by the input data....
The rapidly evolving engineering technology and globalization process have changed educational roles and expectations from teachers. All these lead to some curriculum and teaching reforms that focus on introducing potential programs which provide students with challenging technologies. A recent graduate course “Production Techniques and Technologies” has been developed at University of Bridgeport...
This work presents a new framework for three-dimensional modeling of dynamic fires present in unstructured scenes. The proposed approach addresses the problem of segmenting fire regions using information from YUV and RGB color spaces. Clustering is also used to extract salient points from a pair of stereo images. These points are then used to reconstruct 3D positions in the scene. A matching strategy...
Changes are made to the approximate pole placement iterative feedback tuning algorithm, allowing it to be performed in a simpler manner. Two methods of finding the initial controller parameters for the approximate pole placement algorithm are presented and investigated. The first is based on virtual reference feedback tuning and the second on offline iterative feedback tuning. The initial controller...
Standard based management systems (as quality ISO9001, environmental ISO14001, information security ISO27001, hygiene management systems ISO 22000 and others) are widely implemented and based on common principles: objectives and strategies, business processes, resource management and continuously optimization. These systems contains all relevant information, regulations, forms and process descriptions...
The Top and/or the gyroscope are devices able to produce inertial torques that maintains their direction in space if no external torques are applied. The resulted inertial torques are based on Coriolis forces. Two gyroscopes, placed as near as possible on a platform, may be used as a ‘doublet’ to produce inertial forces and/or torques. As the gyroscope is a ‘gyrator’, the efficiency of such a system...
The paper deals with some active modular groups usually used in the direct structure model of the leg robots or other complex equipment. Such open, un-composed and multi-mobile groups may also be involved in the direct – cinematic or dynamic modeling of the robot displacement for different strategies of motion. There are presented active modular groups with one degree of mobility (the initial active...
E-students vary in terms of online behavior, defined as organized (e.g., web search) and disorganized (e.g., browse) interactions with both human (e.g., chat) and nonhuman (e.g., database) elements in online environments. Online behavior is conceptualized in terms of the dimensions of sociability (human connection motives), utility (efficiency orientation), and reciprocity (the need for cognitive...
Digital divide has been used as a central concept in number of studies, yet this concept has many different definitions. This paper discusses the meaning and definition of digital divide and provides a dichotomy to be used for analyzing different definitions of this concept. Main contribution of this paper is on providing a theoretical dichotomy for understanding the meaning and underlying assumptions...
This paper explores the growing use of virtual world simulations for training and education, both in the private and public sectors. We examine the rise of the importance of the rise of the “digital native” generation and the context of their growing comfort operating in online gaming and increasingly, in virtual worlds. We look at the growth of the video game and virtual world marketplaces and the...
Employer groups have been extensively lobbied the government to introduce key skills development strategy for higher education to produce well-rounded graduates. This is particularly true in professional disciplines such as engineering where discipline specific knowledge rapidly becomes obsolete. Key-skills is the key to success; they help one to excel in the workplace and their importance cannot...
This project involved the creation of 20 introductory industrial hygiene and safety video modules specifically for an M-Learning environment. Testing was performed on 9 modules to determine whether this M-Learning content and presentation was as educationally effective as a traditional lecture presentation. Comparison of test scores and key concepts between two groups of college sophomores and juniors...
A new simplified array configuration based method for estimating the two-dimensional (2-D) direction-of-arrival (DOA) of cyclostationary signals is presented. By eigen-decomposing the pseudo-data Matrices constructed from the cyclic correlation functions of sensor outputs, the proposed method can be applied to not only the wideband but also the narrowband signals. Moreover, the 2-D DOAs can be estimated...
The testing system “UniTeSys” is designed for assessment of student’s knowledge in whatever discipline of high school curriculum. The determination of the field’s discipline is given by generating of suitable database, containing questions, answers and pictures for the curriculum material. The dialog between the system and the tested student is clear and precludes any misunderstandings. The system...
