This paper provides an evaluation of the effects of using the Kumon method for supplementing the teaching of mathematics in the inner-urban school district of Pontiac, Michigan. Michigan Educational Assessment program (MEAP) test scores are cited for Herrington, Owen, and Crofoot elementary schools, which used the Kumon program during part of their ninety minutes of daily mathematics instruction, and demographically matched Emerson Elementary school, which did not use the Kumon program during its ninety minutes of daily mathematics instruction. In 2003, Emerson had 4.5% of its students exceed Michigan standards. In 2004 that number was 8.6%. At Herrington Elementary school, however, the MEAP scores rose from 39.7% to 89.1% of students exceeding state standards during the same single year period. Crofoot went from 0.0% of students exceeding Michigan state standards in 2003, to a remarkable 58.1% exceeding standards in 2004. Owen also showed substantive improvements. The research project, a joint effort between Oakland University's school of engineering and the school District of Pontiac, reveals that supplementation with the Kumon method as a partial replacement for a traditional mathematics program appears to result in significant improvements in statewide Michigan Educational Assessment program test scores for mathematics.

It is known that one of the most disastrous forms of collective human behavior is the kind of crowd stampede induced by panic. This situation often leads to fatalities as people are crushed or trampled. This problem has been well researched from a socio-psychological point of view. In this paper we attempt to study and analyze the crowd behavior by using an ant colony optimization (ACO) based computational framework. The initial simulations refer to a panic situation generated in a few connected cities of a war affected country.

In order to infer intent from gesture, a broad classification of types of gestures into five main classes is introduced. The classification is intended as a generally applicable basis for incorporating the understanding of gesture into human-robot interaction (HRI). Examples from human-robot interaction show the need to take into account not only the kinematics of gesture, but also the interactional context. Requirements for the operational classification of gesture by a robot interacting with humans are suggested and initial steps in its deployment are discussed.

This paper describes an online 3D reconstruction system from stereo image sequences to obtain a dense local world model for robot navigation. The proposed method consists of three components: 1) stereo depth map calculation, 2) correspondence calculation in time sequential images by tracking raw image features, 3) 6DOF camera motion estimation by RANSAC and integrate depth map into 3D reconstructed model. We examined and evaluated our method in a motion capture environment for comparison. Finally experimental results of a humanoid robot H7 are denoted.

Most edge detection algorithms include three main stages: smoothing, differentiation, and labeling. In this paper, we evaluate the performance of algorithms in which competitive learning is applied first to enhance edges, followed by an edge detector to locate the edges. In this way, more detailed and relatively more unbroken edges can be found as compared to the results when an edge detector is applied alone. The algorithms compared are K-Means, SOM and SOGR for clustering, and Canny and GED for edge detection. Perceptionally, best results were obtained with the GED-SOGR algorithm. The SOGR is also considerably simpler and faster than the SOM algorithm.

With the increase in adoption of remote work groups and teams working in non-collocated environments, several opportunities for interaction have been lost. Contact with colleagues and discovery of opportunities, previously easy due to physical proximity, is made harder with distance. In this paper, we describe an agent-based framework to assist users in finding opportunities for interaction that may have been overlooked.

This paper reports the pneumatic PDMS micro finger as an endeffector of robot. The micro finger structures consist of two PDMS films with different mixing ratio of the base polymer and curing agent. An applied air pressure mainly contributes to the generation of the pulling force of the top PDMS layer with excess Si-H group and the large deformation of the flexible bottom layer with excess vinyl group. This combination of the micro finger or hand with a rigid PDMS layer and a flexible one is based on the human being's finger or hand. For the proper structural design rule, in this paper, the micro finer structures with different balloon shape are fabricated and tested by a pneumatic force. While the thickness ratio of the bottom layer and the top one is about 3, the bending angle of micro finger is most sensitive to the applied air pressure. During the repeat test for about 5 hours, there are no any noticeable degradation on the bending motion and the structural failure. The hybrid motion of the micro finger with two or three degree of freedom in micro world and the guide robot in macro world is successfully realized by using VR (Virtual Realty) system.

This paper presents the development of the modeling strategy of the human driving behavior based on the expression as Piecewise Linear (PWL) model focusing on the driver’s stopping maneuver. The driving data are collected by using the three-dimensional driving simulator based on CAVE, which provides stereoscopic immersive vision. In our modeling, the relationship between the driver’s sensory information and the operation of the driver such as braking amount is expressed by PWL model, which is a class of Hybrid Dynamical System (HDS). The identification problem for the PWL model is formulated as the Mixed Integer Linear programming (MILP) by transforming the switching conditions into binary variables. From the obtained results, it is found that the driver appropriately switches the ‘control low’ according to the sensory information. These results enable us to capture not only the physical meaning of the driving skill, but also the decision-making aspect (switching conditions) in the driver’s stopping maneuver.

Active learning enables learners to actively engage in learning. Learning not only transfers material to students for learning, but also encourages greater mental engagement and more extensive student-student and student-instructor interaction than does a typical lecture class. Peer instruction (PI) engages students in active learning by achieving continuous instructor-student interaction in a physics lecture. However, the methodologies and the effectiveness of implementing PI for elementary school students have seldom been clarified. This study explores the possibility of adopting PI in an elementary science classroom. The research considerations of the study are as follows: (1) how wireless technology can enhance PI in elementary science classroom; (2) how a teacher can engage students in pre-class reading, and (3) whether elementary school students have sufficient social skills to perform a PI discussion? These questions are examined by observing how the PI pedagogical model worked with a wireless response system in elementary science classroom. Based on the observation, this study also proposes a way of improving the PI learning experience of elementary school students by adding experiments and observations during peer discussion to explain concepts and phenomena in physics.

Physical Review B 2005年第9期72卷 094115-094115页

作者： Martina E. Bachlechner Jennifer Zhang Ye Wang Jarrod Schiffbauer Steven R. Knudsen Dimitris Korakakis Physics Department West Virginia University Morgantown West Virginia 26506 USA NASA Independent Verification and Validation Facility Science and Engineering Apprenticeship Program—Morgantown High School Morgantown West Virginia 26501 USA Institute for Scientific Research Inc.

Molecular dynamics simulations are performed on parallel computers to investigate the crystalline Si(111)∕Si3N4(0001) interface that is modeled as an eight-component system. The average total energy per particle and the average kinetic energy per particle of the subsystems are monitored during the preparation of the system. The Young’s modulus of the interface is compared with that of the silicon part alone and that of the silicon-nitride film, respectively. The results for one extended simulation feature a crack in the silicon-nitride film and dislocated atoms in silicon below the crack. Simulations at rates of strain ranging from 0.00125to0.05ps−1 show that for lower strain rates, the systems stretched faster reach their ultimate strength at a higher strain value than those that were stretched more slowly. At the highest strain rates, however, the failure mechanisms change qualitatively indicative of a more ductile behavior.
