On the basis of mathematical model of two-wheeled self-balancing electrical motorcycle,we use virtual prototype technology in this paper to build mechanical system model and controling system model of two-wheeled self-balancing electrical motorcycle seperately in ADAMS and MATLAB,and then connect the both by ADAMS/Control interface module for realising interactive simulation of control under software system environment. Practice proves co-simulation of dynamic system and control system have promoted efficiency and reliability of two-wheeled self-balancing electrical motorcycle designing,and it is a precise and high efficient optimal design method. © 2011 IEEE.

In this paper we apply and test a recent ordinal algorithm for classification (Kernel Discriminant Learning Ordinal Regression, KDLOR), in order to recognize a group of geographically close spatial units with a similar prevalence pattern significantly high (or low), which are called hot-spots (or cold-spots). Different spatial analysis techniques have been used for studying geographical distribution of a specific illness in mental health-care because it could be useful to organize the spatial distribution of health-care services. Ordinal classification is used in this problem because the classes are: spatial unit with depression, spatial unit which could present depression and spatial unit where there is not depression. It is shown that the proposed method is capable of preserving the rank of data classes in a projected data space for this database. In comparison to other standard methods like C4.5, SVMRank, Adaboost, and MLP nominal classifiers, the proposed KDLOR algorithm is shown to be competitive.

This article reports findings from a classroom environment study which was designed to investigate the nature of Chinese Language classroom environments in Singapore secondary schools. We used a perceptual instrument, the Chinese Language Classroom Environment Inventory, to investigate teachers' and students' perceptions towards their Chinese Language classroom learning environments using six dimensions, namely, Student Cohesiveness, Teacher Support, Involvement, Cooperation, Task Orientation and Equity. The investigation was carried out using a sample of 1,460 secondary three (Grade 9) students from 50 Chinese Language classes in 25 Singapore government secondary schools. The nature of the Chinese Language classroom learning environments was interpreted from analyses of the perception scores obtained, as well as from various comparisons of the perception scores between different groups. Although both the Chinese Language teachers and students perceived their present classroom learning environments positively, they would like improvements in all the six dimensions of the classroom learning environments under investigation. Also teachers perceived a more positive classroom learning environment than their students in the same class. In addition, female students perceived their actual and preferred classroom environments more positively than their male counterparts. © 2011 Springer science+Business Media B.V.

Synchronization is very important for the efficient processing and transmission of information across the nervous system. Synchronization processes are ubiquitous in nature and play a very important role in many areas. As a special neural networks, fuzzy neural networks have an automatic adoption procedure and attract many attentions to their dynamical behaviors. In this paper, delayed fuzzy high-order Cohen-Grossberg neural networks with reaction-diffusion term is present and their synchronization is discussed. Some sufficient conditions are given to ensure the synchronization of the drive-response delayed fuzzy high-order Cohen-Grossberg neural networks. Copyright © 2011 Binary Information Press.

In this paper, the exponential synchronization of a class of Cohen-Grossberg neural networks with delays and diffusion terms is discussed. By using Lyapunov functional method and Sobolev inequality, some sufficient conditions are given to ensure the exponential synchronization of the drive-response cellular neural networks with delays and diffusion terms.

A new model for equipment selection and transfer line design problem

Abstract We suggest a new mathematical model for the equipment selection and the design of a transfer line intended for a mass production of machine parts of the same type. The transfer line is a sequence of (work)stations equipped with processing modules (blocks) each of which performs specific operations. Each machine part moves along the transfer line in the same direction and undergoes a given set of operations at the stations. There is the same cost associated with each station and different costs associated with the blocks. The problem is to determine the number of stations, to select a set of blocks from the set of available blocks and to assign these blocks to the stations so that each operation is performed exactly once and the total cost is minimized. The peculiarity of the problem is that all operations of the same station are performed in parallel, the assignment of the blocks and operations to a station are restricted by exclusion and inclusion relations, and the processing order of the operations on the transfer line must comply with precedence relations. We suggest a reduction of this problem to a set partitioning type problem. The reduction is based on a new concept of a locally feasible station.

A theory of desynchronisable closed loop systems 3

A theory of desynchronisable closed loop systems

3rd Interaction and Concurrency Experience Guaranteed Interaction, ICE 2010

作者： Beohar, Harsh Cuijpers, Pieter Formal Methods Group Department of Mathematics and Computer Science Eindhoven University of Technology Netherlands

The task of implementing a supervisory controller is non-trivial, even though different theories exist that allow automatic synthesis of these controllers in the form of automata. One of the reasons for this discord is due to the asynchronous interaction between a plant and its controller in implementations, whereas the existing supervisory control theories assume synchronous interaction. As a consequence the implementation suffer from the so-called inexact synchronisation problem. In this paper we address the issue of inexact synchronisation in a process algebraic setting, by solving a more general problem of refinement. We construct an asynchronous closed loop system by introducing a communication medium in a given synchronous closed loop system. Our goal is to find sufficient conditions under which a synchronous closed loop system is branching bisimilar to its corresponding asynchronous closed loop system. © *** & ***.

Quantifying the development of inflectional diversity

First Language 2010年第2期30卷 175-198页

作者： Xanthos, Aris Gillis, Steven Department of Computer Science and Mathematical Methods University of Lausanne Anthropole CH-1015 Lausanne Switzerland University of Antwerp Belgium

This study introduces a new metric for assessing the inflectional diversity of morphologically analyzed language transcripts. The proposed metric is based on the intuitive notion of mean size of paradigm (MSP) and makes extensive use of random sampling procedures for normalization purposes. This approach is systematically evaluated on the basis of large sets of Dutch acquisition corpora, including both child speech and child-directed speech. It is shown to be an efficient way of controlling for sample size in the measurement of inflectional diversity, as well as a suitable method for assessing inflectional development in longitudinal data. MSP is compared with ID (inflectional diversity) introduced by Malvern, Richards, Chipere, and Durán (2004). © The Author(s) 2010.

computer science (CS) Education research, specifically when focusing on secondary education, faces the difficulty of regionally differing political, legal, or curricular constraints. To date, many different studies exist that document the specific regional situations of teaching CS in secondary schools. This ITiCSE working group report documents the process of collecting, evaluating, and integrating research findings about CS in secondary schools from different countries. As an outcome, it presents a category system (Darmstadt Model), as a first step towards a framework that supports future research activities in this field and that supports the transfer of results between researchers and teachers in CS education (CSE) across regional or national boundaries. Exemplary application of the Darmstadt model shows in several important categories how different the situation of CSE in secondary education in various countries can be. The Darmstadt Model (DM) is now ready for discussion and suggestions for improvement by the CSE community. © 2011 ACM.
