    Automation of photogrammetric tasks by means of manipulator robots is a complex problem. It involves many planning and controlling aspects that reflect on the overall system performance in terms of precision and efficiency. This paper deals with the problem of task distribution for a multiple manipulator work cell with the goal of obtaining highly accurate object measurements. Task distribution is separated into two independent combinatorial optimization problems: activity assignment and tour planning. These problems are solved simultaneously by an optimization method based on genetic algorithms. This method implements a series of restriction-based heuristics in order to utilize a simple genetic representation similar to random keys. Experiments that validate the effectiveness of our approach are presented View full abstract»

    The effectiveness of VR (virtual reality) systems is well documented, but there are no guidelines for determining the influence that such systems have on humans, particularly with regard to adaptation to the VR environment. The results of an experiment are summarized as follows: 1) A VR experience using an HMD made the integration of sensory information in the equilibrium nucleus confusing. 2) Sensory conflict caused motion-sickness-like symptoms in the subjects. 3) As a result of equilibrium deterioration, movement velocity, movement distance, and sway area of the center of pressure were increased. These results suggest that the VR experience causes motion-sickness-like symptoms and worsens equilibrium View full abstract»

    We propose using the information revealed through auctions, including in particular the unsuccessful bids, to identify latent demand. Applied to combinatorial auctions for bundles of goods, this information can identify new bundles with particularly high valuations, expressed by their high complementarity. We present a simple algorithm for identifying these bundles, suitable for use with agent-based ecommerce systems View full abstract»

    The paper presents an information compressing 3-dimensional user interface on the support system of requirement extraction from a BBS (Bulletin Board System). To correspond to users' viewpoints, the Fish-Eye is applied. With the Fish-Eye, a size of an object on the output screen is decided according to the user's attention. This function is realized in topic groups, opinion cards and text in cards respectively. A way of applying Fish-Eye with regards to the topic groups and opinion cards is to show the objects on the inclined coordinates from viewpoints. To realize the Fish-Eye for letters, the priority is set on each sentence in the opinion. The priority is decided from the character of conversational structure, which has a tree structure. With this structure, the attention of the user is specified and is reflected in selecting which sentences should be written in the opinion cards View full abstract»

    Decentralized production structures are able to cope with turbulences such as e.g. customer specific products with increasing complexity, fluctuations of demand and shortened product life cycles. Several concepts have therefore been developed successfully (e.g. production segments). In contrast to these decentralized structures, order management is based mostly on centralized concepts. To solve the problems of centralized planning for a decentralized organization structure and to realize the potentials of these structures, an approach of flexible time-frames is developed. The aim of this approach is to discover the optimization potentials (e.g. set up time, material input, etc.) in pooling orders, with consideration of the effects on central logistic indicators e.g. throughput time, work in process or utilization. Feedback loops support the method of flexible time-frames and help to create a continuous improvement process for rough and detailed scheduling of orders as well as the design of products and production structures. The described method allows one to handle disturbances (e.g. in the supply chain) or extremely short planned orders, which is the basis for a robust and agile production system View full abstract»

    This paper describes the architecture of a Web-based audio/video educational system for real-time laboratory experiments through the Internet. The goal of the WAVES (Web-based Audio Video Educational Systems) project is to develop an open and integrated platform for online laboratory experimentation, computer simulation, and course instruction using the Internet for research and teaching in modeling, design, analysis, and control of dynamical systems. The project is unique in that students can conduct hardware lab experiments via the Internet and receive real-time data feedback and audio/video feedback of experimented results. Although many similar Internet-based tools have been developed throughout the last two years, very few of them encompass "hands-on" experiments with actual laboratory hardware. Since Internet-based hardware systems can be shared and scheduled for use by a large number of researchers and students in various locations, the WAVES platform is a cost-effective way to address the issue of "hands-on" experience for students. In our current implementation, a three layer architecture is used, i.e., the clients, the dispatcher, and the coordinators. First, the clients will issue tasks and receive feedback for conducting a specific lab experiment; then the dispatcher deals with the control and communication between the clients and coordinators; finally the coordinators conduct the actual experiment through hardware setups, simulation models, and database systems View full abstract»

    Using e-commerce over the Internet is very cheap and convenient, which enlarges the view of enterprises and lets the enterprises have more chances to select their partners. To achieve these goals, we need the support of information systems, in which workflow management system is of significance. The inherent characteristics of a workflow system make it suitable to implement the cross organization management. Nowadays, however, systems which support cross organization management are not common. When developing a supply chain management system for a big motorcycle corporation in China, we have to construct an inter-enterprises workflow Architecture over Internet for the system by ourselves. The main part of the Architecture is a workflow supported inner supply chain and an integrated interface, through which the whole supply chain system cross several independent enterprises is constructed and the information exchange is fulfilled. This paper introduces how the system is designed and implemented in detail View full abstract»

    This paper introduces a robust adaptive control architecture for nonholonomic mobile robots. The concept of backstepping provides a bridge between the kinematics and dynamics. In previous work normally only the vehicle steering, dependent upon the kinematics are considered for vehicle control. Improved tracking performance is achieved by including vehicle dynamics and robustness compensation for variances in parameters. Numerical simulations demonstrate the effectiveness of the robust adaptive control algorithm View full abstract»

    A long-standing reservoir simulation problem in petroleum engineering is history matching, where a reservoir simulator is "calibrated" in some way to model the reservoir under study. A correctly calibrated simulator can be used for reservoir characterization and provides a cost-effective way of obtaining essential information about the reservoir. The history matching problem seeks to find a set of suitably adjusted input parameters of the simulator such that the simulator correctly predicts the fluid (oil, gas, water, etc.) outputs of the wells on the reservoir, over the period of time of interest. The history-matching problem is theoretically simple but frequently intractable in practice because of three significant issues: the scale of the problem; lack of reasonably affordable computational resources for many oil operators who need to do the simulation; and the need for human intervention in the process. This paper presents a solution by utilizing soft computing and Web computing techniques View full abstract»

    In this paper, we will present the multi-lateral security framework for the ubiquitous audiovisual services. Next generation audiovisual services are expected to be very flexible digital system build on the global broadband network and they allow us to access any audiovisual contents at anywhere in the world. We call it ubiquitous audio-visual services. In such new services, several new security criteria, may become more important. Maintaining competitive market, privacy protection and suppression of organized crimes are drawing broader interest than before. Since past discussion on the contents security was often narrowly focused on the closed system, technological framework and architecturectural design which covers new requirement issues was not analyzed enough in technical context. In this paper, firstly we will discuss on the concept of multi-lateral security, which can be bases of technical security requirements. Then secondly, we will describe a technology to improve system in terms of multilateral security View full abstract»

    A new emerging area of research and technological development, set forward by the requirements of today's progressive industries, is the paradigm of virtual organisations. A meta-data repository is the logical place for uniformly retaining and managing corporate knowledge within or across different members of such organisations. Many meta-data architectures are not optimized for information retrieval purposes. Taking into consideration the existence of different data types and attributes, many problems arise when we try to successfully merge search results from heterogeneous sources. Motivated by these observations, this paper investigates a new architecture that can support multiple meta-data abstractions and that is readily extensible. Modularity and extensibility are the design emphases View full abstract»

    Agent-based electronic commerce (e-commerce) has attracted more and more efforts in academic and industrial fields. However, little work has been devoted to exploring the learning and evolving capability of software agents. This paper addresses issues of evolving software agents in e-commerce. Agent structure and organization are introduced to facilitate the evolution process, and agent fitness and life cycle are employed as evolution mechanisms. Two approaches are proposed to equip agents with evolution features. One approach is to use Genetic Programming (GP) operators to restructure agents. Another one is to enhance the knowledge of agents by exchanging with other agents View full abstract»

  • Large-scale feature identification for indoor topological mapping

    The paper describes a new approach to creating a map of the environment for a mobile robot by identifying large-scale indoor features directly from sonar observations. Current research in creating environmental maps for mobile robots either use grid-based representations, or use small-scale features to construct larger entities for topological maps, or use combinations of these approaches. These methods do not directly identify features on the scale of corridors, alcoves, and intersections that have high semantic content for people and provide a compact representation of the topology of the environment. We present a simple rule-based technique to differentiate and identify a set of large-scale indoor features. The rule-based approach is used to demonstrate the potential of our method. The experimental results show that processor intensive techniques such as pattern recognition/signal processing, neural networks, or clustering algorithms may not be required for successful, direct large-scale feature identification View full abstract»

    This paper describes the aspects involved in modelling a multi-robotic system from a human motor control perspective. Building a control system for a multi-robot system that works in a similar fashion to the human motor control system would require a decomposable model. Decomposition of a complex robotic system is difficult due to the interactions between the subsystems. The proposed method of separating the interconnections is applied with the aid of fuzzy modelling to derive a fully decomposable model of two manipulator robots handling a common object View full abstract»

    A key requirement for a dynamic organization is the need for precise and formal knowledge management of the available information. The main objective of our work is to provide an agent based model of an agile integrated business system, more specifically, of the marketing sector of the company, where the knowledge has to be acquired, shared both internally and externally, updated, processed, applied, used and reused in order to find correlations among knowledge from different company sectors. Agents are able to suggest certain operations to the users in response to the change in the data structures they are responsible for maintaining. They can adopt using prior knowledge about company objectives and available customer data. An important role of the agent is to learn and change its practice according to previous approved behavior. The use of fuzzy set theory, in order to maintain and analyze the knowledge kept in the company profiles, as well, as to calculate the reliability of the suggested actions, showed the first positive experimental results. We applied this model for the operation of the Center for Distance Learning, for analysis of the different marketing campaigns and as a consultant for future campaigns View full abstract»

    The Advanced Tactical Architecture for Combat Knowledge System (ATACKS, formerly known as ABATIS) has been designed as a visualization tool to support commander's decision-making in a complex battlespace environment. ATACKS expands standard battlefield symbology by providing symbols for Stability and Support Operation (SASO) on three dimensional (3D) abstract battlespace terrains. Furthermore, it extends normal spatial visualization through process centered displays that seek to enhance the commander's understanding of the situation by presenting qualitative data in novel formats. In addition, external decision support tools communicate with ATACKS, through an application program interface (API) that can allow communication over a network as well as between systems on differing operating systems. With this capability, ATACKS can serve as an integration point for intelligent aiding systems' View full abstract»

    In this paper, we propose a system of evolving virtual robot structures in three-dimensional space. It is possible to obtain the structure of robots suitable for the virtual environment. We regard a robot as the combination of some functional parts (modules). To evolve the structure of robots, we use the technique of genetic programming. Grounds represented by some functions are assumed as the environment. Through computer experiments, it is confirmed that various structures of robots suitable to the environment can be obtained View full abstract»

    The article proposes an alternate view on natural language parsing. Instead of looking for some predefined (phrase) structure it takes inter-word relations as a starting point. The reason for this is twofold: firstly it circumvents traditional parsing and linguistic problems and secondly it offers a possibility to extract information specifically needed by IR applications. The close relationship with index expressions opens the door to feedback mechanisms like 'Query By Navigation' (P.D. Bruza and T.P. van der Weide, 1992) and conceptual knowledge extraction (F. Grootjen, 2000). The presented ideas are accompanied by an implementation and a small scale experiment View full abstract»

    As the already vast number of home Web users continues to grow the Web is emerging as an alternative medium for satisfying information needs that arise outside the organisational/work domain. As the number of organisations using the Web as a medium for disseminating information increases there has been little, if any, evaluation of the effectiveness of the Web as an information resource for satisfying information need. This paper reports on research that builds on recent work developing conceptually-based scales for evaluating the extent to which Web services satisfy information needs that arise outside the traditional organisational/work domain. The results of a Web-based survey which generated 720 responses are reported View full abstract»
