Quantile-based spectral analysis in an object-oriented framework and a reference implementation in R: The quantspec package

Abstract: Quantile-based approaches to the spectral analysis of time series have recently attracted a lot of attention. Several methods for estimation have been proposed in the literature and their statistical properties were analyzed. Yet, so far, neither a systematic method for computation nor a comprehensive software implementation are available to date. This paper contains two main contributions. First, an extensible framework for quantile-based spectral analysis of time series is developed and documented using object-oriented models. A comprehensive, open source reference implementation of this framework is provided in the R package quantspec, which is available from the Comprehensive R Archive Network. The second contribution of the present paper is to provide a detailed tutorial, with worked examples, for this R package. A reader who is already familiar with quantile-based spectral analysis and whose primary interest is not the design of the quantspec package, but how to use it, can read the tutorial and worked examples (Sections 3 and 4) independently.

An object-oriented design approach for developing hypermedia information systems

Abstract: Hypermedia system design is a difficult process, mainly because of the lack of high‐level hypermedia design models and support tools. The approach presented herein is intended to solve this problem. Its main elements are the Enhanced Object‐Relationship Model and two support tools for schema design and graphical user‐interface (GUI) design, all based on a common object‐oriented database system. The approach leads to schemas that will serve as design specifications; it can be used for documentation purposes; it paves the way for reuse of hypermedia designs; it allows integration with other object‐oriented systems and non‐object‐oriented systems; and it can lead to systems where the main interaction style is based on hypermedia linking. Finally, the approach offers a foundation for a unique combination of a high‐level hypermedia design methodology and reusable designs, which is expected to have a major impact on the future use of hypermedia in information systems.

Virtual object management system for managing virtual objects which correspond to real objects under a user defined hierarchy

Abstract: An object management system is equipped with a single real object management system for managing a real file object such as data and a program based on a real directory object in a hierarchical structure, and also at least a single virtual object management system for managing a virtual file object corresponding to said file object based upon a virtual directory object which is independent of the directory object in a hierarchical structure.

Making object learning and recognition an active process

Abstract: The exploration and learning of new objects is an essential capability of a cognitive robot. In this paper we focus on making use of the robot's manipulation abilities to learn complete object representations suitable for 3D object recognition. Taking control of the object allows the robot to focus on relevant parts of the images, thus bypassing potential pitfalls of purely bottom-up attention and segmentation. The main contribution of the paper consists in integrated visuomotor processes that allow the robot to learn object representations by manipulation without having any prior knowledge about the objects. Our experimental results show that the acquired data is of sufficient quality to train a classifier that can recognize 3D objects independently of the viewpoint.
