IEEE SENSORS

作者： Seiichi Teshigawara Satoru Shimizu Kenjiro Tadakuma Ming Aiguo Makoto Shimojo Masatoshi Ishikawa Mechanical Engineering and Intelligent Systems University of Electro-Communications Chofu Japan Department of Information Physics and Computing Graduate School of Information Science and Technology University of Tokyo Bunkyo Tokyo Japan

Slip detecting tactile sensors are essential to achieve a human-like gripping motion with a robot hand. In previous researches, we have proposed flexible, thin and lightweight slip sensor utilizing characteristics of pressure conductive rubber. However, It was hard for this sensor to distinguish between the object slip and the normal force change. Therefore, we consider the separative method using high frequency elements generated by object slipping. In this paper, we design the information processing method and developed the sensor detecting both contact and initial slip in high sensitivity and a simple composition.

This paper proposes novel techniques for the improvement of the convergence characteristic of step-by-step time integrations in nonlinear transient eddy-current analyses. The proposed methods, which are based on the time-periodic finite-element method and the explicit error correction method, can extract poorly-converged error components corresponding to large time constants of an analyzed system. The correction of the extracted error components accelerates the convergence of transient calculation efficiently. Furthermore, we extend the performance of the proposed methods in nonlinear problems. Some numerical results that verify the effectiveness of the proposed methods are also presented. © 2009 The Institute of Electrical Engineers of Japan.

In this paper, we introduce wavelets on the interval [0, 1] in 3D wavelet moments, which we call 3D interval wavelet moments. Based on these, new descriptors for 3D objects are put forward. They are invariant to translation, rotation and scale, and have the multi-resolution features in the radial direction, which can handle noise to some extent and provide multi-level features to satisfy various requirements. Furthermore the new method is prior to the original 3D wavelet moments on the presentation of the edge of the objects. They have fast Mallat algorithm too. With the Pearson correction in each level, we give a new method to measure the similarity of two objects. © 2009 Binary Information Press.

Recurring problems in the application of a new software process improvement model have to do with the lack of knowledge about how it works, its dissemination and the tools available, making it difficult to acquire the model and then understand it. Nowadays, e-learning systems could help Very Small Software Entities (VSEs), to get to know and understand software models and their peculiarities. To address this issue, this paper focuses on the development of a tool based on e-learning standards;it is called the HEPALE! Project. This project is composed of three steps. First, the creation of a deployment package set, in line with ISO/IEC PDTR 29110-5-1 Software Engineering-Lifecycle Profiles for VSEs, for implementing software process improvement models, as well for making them easier to use. Secondly, the creation of a repository that supports changes in the deployment packages, based on e-learning standards and tools, to create, represent, interact with and manipulate learning objects and e-learning. Finally, the last part aims to spread the software development models COMPETISOFT and ISO/IEC 29110-5-1, the application of technologies that make use of e-learning. All this is done to aid VSEs in bringing best practices into their software production.

Virtual project teams are spontaneous group configurations that endeavor to overcome spatial and temporal restrictions in bringing together distant experts to create just-in-time knowledge sharing coalitions. Due to their time-constrained nature and the anonymity among members, we believe that team goal commitment might be a more pertinent factor driving task performance. We hypothesize that members' perceived distributive, interactional, and procedural justice are viable antecedents leading to the inducement of team goal commitment among virtual project team members. A longitudinal field experiment was carried out to test these hypotheses. The results suggest that: (1) distributive justice is a consistently strong predictor of team goal commitment over time;(2) the effect of interactional justice on team goal commitment manifests over time, and;(3) procedural justice has no effect on team goal commitment over time. Implications for both theory and practice are discussed. © 2008 IEEE.

Though contemporary research has testified to the importance of social presence in influencing the format and structure of group processes, its unidimensional nature and inability to accommodate asynchronous communication has eroded its relevance in the face of more sophisticated IT-based collaborative networks such as virtual project teams. Kumar and Benbasat [25, 26] thus advanced the notion of Para Social Presence (PSP) as a broader, encompassing concept that overcomes the aforementioned weaknesses inherent in the existing social presence construct. Yet to-date, there has not been a theoretical and empirical validation of the pertinent of the PSP construct when applied to more dynamic group configurations as claimed. To this end, this study reviews extant literature to first establish whether the PSP construct is meaningful conceptually and then empirically validates its measurement properties over time through a temporal field experimentation setting. © 2008 IEEE.

Learning styles are considered as an important factor in education, however, often students have to learn from material or in courses which do not support their learning styles. A challenge in the area of adaptivity is not only to provide learners with courses that fit the students' learning styles but can also veer towards supporting students to learn in courses that does not match their learning styles. In this paper, we analyse the interactions between students' learning styles, their achievement, and their general behaviour in a course that is mismatched regarding their learning styles. The impact of the strength of learning style preferences on achievement, correlations between particular learning styles and achievement, as well as students' behaviour with respect to their achievement and their learning styles are analysed and discussed. As a result, we found that students with strong learning style preferences have more difficulties in learning in mismatched courses. Furthermore, the results show that reflective learners can cope better with mismatched courses than active learners. Moreover, we found that learners with different learning styles and achievement have different behaviour in the course as well as identified correlations between the behaviour and the achievement considering the students' learning styles. The results of this study help, on one hand, to get a better understanding of the interactions between students' learning styles, achievement, and behaviour in a mismatched course and, on the other hand, provide information about how to identify learners who might face difficulties in learning in a mismatched course.

Many researches have been conducted with respect to learning styles in technology enhanced learning, especially in the area of adaptive learning. Most of these researches used assumptions about how students with different learning styles behave in a system based on the respective learning style theory. However, most of these theories are developed for traditional learning rather than online learning. In this study, we investigated the behaviour of students in a learning management system and correlated the students' behaviour with their learning style preferences. The resulting correlations confirm that students with different learning styles behave differently in an online course, which gives another evidence for the potential of adaptive learning based on learning styles. Furthermore, our findings can contribute in the development of adaptive systems, making adaptive features more accurate and automatic student modelling more precise by combining the results of this study with the conclusions from literature.
