The recent and rapid advances in hardware have led to an explosion of real-time and concurrent applications, especially real-time control system applications. This, in turn, requires practical software development with new technologies such as Object- Oriented Analysis and Design (OOAD), Model-Driven Development (MDD) with the Unified Modeling Language(More)
A new server-decentralized Internet architecture based on Jabber for robot remote control is proposed in order to have high availability, performance, scalability, fault tolerance and security. Four components of the architecture: operators, robots, transfer servers and data-keeper are defined and functioned. The robot-controlling data/robot state data are(More)
A subsystem for controlling and managing the closed-shelf stacks of Beijing Institute of Technology Library is developed. The implementation of the proposed subsystem's functions and the scheme for optimizing schedules scheme are discussed. Traditionally, the book selection process is time-consuming and inefficient. To address this problem, an improved(More)
Real-time indoor location determination is indispensable for an autonomous robot. It can also provide various location-based services for other applications. In this paper we set up an indoor positioning system (IPS) framework consisting of an array of iBeacons that are fixed in the environment to send signals and an android phone as the positioning device(More)
Aiming to improving the exception handling capacity of BPEL process, this paper explores a policy-based exception handling method for BPEL processes. The paper propose a policy-based exception handling description language EHPDL-P, and design a framework to support the implementation mechanism of exception handling process based on EHPDL-P. Finally, through(More)
Glycidyl fatty acid esters (GEs) are by-products of edible oil refinement that have attracted attention globally due to concerns over their possible harmful effects on human health when consumed. It is thus important to improve our understanding of GE formation if we are to suppress GE production during edible oil refinement. In this paper, a(More)
This paper presents a parallelization method for the computation of interactive physical simulations. In the method, physical simulation tasks are split into multiple sets of tasks using a space partitioning algorithm. Each task set is assigned to a working thread running on a multicore processor. In order to achieve dynamic workload balancing, a work(More)
A simulation platform was introduced to build robot simulation model more conveniently and quickly for the networked robot operating system based on augmented reality. Encapsulating most of the basic OpenGL functions, the platform was organized in a layered structure and made up of two kinds of nodes: geometric nodes and action nodes. Multiple geometric(More)
