REAL: a virtual laboratory for mobile robot experiments

This paper presents REAL (Remotely Accessible Laboratory), a virtual laboratory accessible through the Internet. The objective of REAL is to provide remote access to a mobile robots infrastructure. REAL has been implemented as a new generation telecommunication service, not as a commonplace World Wide Web (WWW) application. As such, it employs a sophisticated access framework, a communication infrastructure able to support multimedia flows, and a component-based software construction. The architecture of REAL relies on open standards, such as WWW and its related technologies (HTTP, HTML, XML, Java, etc.) and a common object request broker architecture (CORBA).     

The significance of telemedicine in a rural emergency department

Telemedicine is evolving into an important tool in delivering services to emergency departments (EDs) in rural areas. However, we do not yet know what kinds of services can be effectively delivered or the degree to which these services might be useful. In this pilot study, a high-speed, high-quality video, 24-hour ATM (asynchronous transfer mode) network linked a rural ED to an ED of a major medical center. The objective was to measure the utilization of telemedical consulting services. Specifically, this one-year study examined the significance of telemedicine in changing diagnosis and treatment and the influence on patient transfers

基于D-S证据理论的水利工程招标评价

如何从多个水利工程招标方案中选取最佳方案是决策者需要面临的一个难题。针对上述多属性决策问题,选取某实例,首先采用投影寻踪模型将其降维转化为一维问题决策,获得指标的客观权重;随后,采用德尔菲法,获取指标的主观权重。为有效地合成主、客观权重,采用D-S证据理论进行权重合成得到更为合理的指标权重,进行方案的最终优选排序,并与其它评价方法进行了比较。结果表明：本文方法能有效地利用主、客观信息,所得的结果更为科学、合理,从而提高了评标工作的科学性。

Localization and control of a rehabilitation mobile robot by closehuman-machine cooperation

In the field of rehabilitation robotics, a mobile personal robot represents an attractive solution, especially in economic terms in comparison with a desktop workstation. A manipulator arm mounted on a mobile robot can facilitate the restoration of the disabled user's manipulative function. In order both to encourage the person to participate in the task at hand and to be cost effective, close human-machine cooperation is essential. The person controls the robot via a remote station and develops strategies to successfully carry out a mission. The main problems encountered by the person during the execution of a mission are electing to change modes, and the mode transition itself. The authors have examined two aspects of this cooperation: 1) information exchange between human and machine for decision-making and 2) giving to operators complementary and redundant modes to command the system. An experiment has been conducted to study these two aspects. This paper focuses on the control of robot movements in an indoor environment and especially on localization parameters, human-like robot behavior, and the value of proposing complementary control modes to the operator

LabBase: managing lab data in a large-scale genome-mapping project

The Whitehead/MIT Center for Genome Research is engaged in several high-throughput genome-mapping projects, including physical mapping of the human genome and genetic-linkage mapping of the mouse genome. The scale and complexity of the laboratory workflows for these projects make a laboratory information system a necessity. For example, the human physical mapping project has performed over 1.2 million experimental steps to date, many of which involve numerous biochemical assays. The result is a physical map containing over 13 thousand sequence-tagged-site markers, with a near-term goal of 15 thousand markers. These markers will likely be used as a starting point for producing a higher resolution map, which in turn will provide the raw material for sequencing the human genome. LabBase is a database management system (DBMS) tailored to the needs of laboratory information systems that support such projects. It is designed to make it easy to keep track of laboratory samples, the experimental steps performed on them, and the results of these experiments. LabBase is functionally specialised because it provides special support for the requirements of managing laboratory data over and above what would be provided by a generic, off-the-shelf DBMS     

Detection of moving object by mobile stereo omnidirectional system (SOS)

Moving object detection with a mobile image sensor is an important task in robotics and computer vision, when considering the practical use of robotics in human environments. In this paper, we propose a robust method that detects moving objects in the environment using the omnidirectional depth information obtained by a mobile Stereo Omnidirectional System (SOS). In order to detect only the moving objects within the depth image that are obtained by a sensor in motion, we first estimate the ego‐motion of the sensor, and generate a predicted depth image for the current time from the depth obtained at the previous time by only considering the ego‐motion of the sensor. Then the predicted depth image is compared with the actual one obtained at the current time, and the inconsistent regions are detected as moving objects. When the sensor moves, occlusions will occur in the scene and they will cause false detections. However, these false detections can be suppressed by estimating the occlusion regions using the ego‐motion parameters of the sensor and the jump edges in the depth image. The effectiveness of the method is shown with experimental results for a real environment. © 2005 Wiley Periodicals, Inc.
