To improve the positioning accuracy of servomechanisms with one single actuator only, the dual-stage actuator (DSA) systems have been proposed and widely used for industrial applications for the benefits of both large working range, high positioning accuracy and fast response. However, it is common that servomechanisms suffer from plant uncertainties and external disturbances which will affect the positioning accuracy. As such, this paper studies a robust control method called fast non-singular terminal sliding mode (FNTSM) control for a class of DSA systems. Compared with conventional sliding mode control, the FNTSM control can guarantee a faster convergence rate of the tracking error in the presence of system uncertainties including payload variations and external disturbances. Furthermore, it has the inherent feature of chattering-free in the control input. We also discuss the selection criteria of the controller parameters and then the FNTSM control method is applied to design the two control inputs of the DSA system. Simulations are studied to verify that the FNTSM controller can offer robust performance with respect to the mass variations and disturbance. Tracking performance achieved by conventional linear controllers is also presented for comparison.

The Astropy project supports and fosters the development of open-source and openly-developed Python packages that provide commonly-needed functionality to the astronomical community. A key element of the Astropy project is the core package astropy, which serves as the foundation for more specialized projects and packages. In this article, we provide an overview of the organization of the Astropy project and summarize key features in the core package as of the recent major release, version 2.0. We then describe the project infrastructure designed to facilitate and support development for a broader ecosystem of inter-operable packages. We conclude with a future outlook of planned new features and directions for the broader Astropy project. Copyright © 2018, The Authors. All rights reserved.

The Semantic Web, supported by Ontology, is considered as an important evolution to deal with the semantic heterogeneity of the Internet. As different communities build ontologies, it is imperative that methods for mapping and merging of ontologies are developed. This is for achieving the semantic interoperability and assuring relevance in information retrieval. A weighted evaluation approach for ontology integration is considered in this research paper. This work focuses on the semantic layer of ontology mapping. The authors also outline some requirements for a methodology in building ontology in a specific domain, apart from integration.

This paper introduces a recently published Python data mining book (chapters, topics, samples of Python source code written by its authors) to be used in data mining via world wide web and any specific database in several disciplines (economic, physics, education, marketing. etc). The book started with an introduction to data mining by explaining some of the data mining tasks involved classification, dependence modelling, clustering and discovery of association rules. The book addressed that using Python in data mining has been gaining some interest from data miner community due to its open source, general purpose programming and web scripting language; furthermore, it is a cross platform and it can be run on a wide variety of operating systens such as Linux, Windows, FreeBSD, Macintosh, Solaris, OS/2, Amiga, AROS, AS/400, BeOS, OS/390, z/OS, Palm OS, QNX, VMS, Psion, Acorn RISC OS, VxWorks, PlayStation, Sharp Zaurus, Windows CE and even PocketPC. Finally this book can be considered as a teaching textbook for data mining in which several methods such as machine learning and statistics are used to extract high-level knowledge from real-world datasets.

Testing is the last step to check the correctness of a software system. However, due to its incompleteness, we still do not know if the implementation behavior matches the design behavior. In this paper, we provide a new solution for web applications. Since web application has special navigation character, we can get rich information in the log file after testing. From such log file, we extract the Petri net based behavior of the web application. The behavior is then checked by SPIN. Market Information System has been adopted as the case study. © 2010 IEEE.

Verlhust logistic map f(x) = r x (1 - x) is a widely studied and applicable model in discrete dynamical system. Its behavior has been, extensively, studied in Picard orbit and recently studied in superior orbit. Rani et. al. [22] and [25] has shown that in superior orbit, logistic map is stable for larger values of r than that of Picard orbit. In this paper, we have attempted to make the map stable for further larger values of r via I-superior iterates. © 2010 IEEE.

With the technology of sensor, RFID, and GPS, many researches are recently being carried out on monitoring animal behavior and interactions with the environment. Plus, the technology is applicable to develop new zoological systems for animal trace ability, identification, and anti-theft. Yet, there is a lack of studies of providing zoos with intelligent animal tracking and management services based on RFID, GPS, and sensors. Accordingly, in this paper, we propose an intelligent animal situation tracking service for zoological gardens, based on GPS, RFID, and sensors. Firstly, we present a service scenario of animal situation tracking and introduce the tracking system configuration. The proposed system can provide real-time animal situation information such as the current location, bodily temperature, and pictures. Plus, it can track the animals based on the information even when they escape their cages. Next, we design and implement a prototype of the proposed animal situation tracking system.
