Originated from Robot World Cup Middle Size League (RoboCup MSL), this paper discusses the design and implementation of a robot soccer simulation system based on ROS and Gazebo. Its aim is to test multi-robot collaboration algorithms. After building the Gazebo models, a model plugin is written to realize the robot's basic motions including omnidirectional locomotion, ball-dribbling and ball-kicking...
Nowadays, with the rapid development of distributed computing, message distribution has been more and more important to distributed systems. Kafka was developed to collect and distribute massive messages for distributed systems. It is a high-throughput distributed messaging system. Kafka can always keep stable performance even if it processes millions of messages per second. Messages are persistent...
During the past ten years, cloud computing gradually becomes mature which is a current research hotspot. OpenStack is currently one of the most popular open source cloud platforms that developed by Rack space and NASA. It provides some toolkits to deploy cloud environment and implement cloud infrastructure like Amazon EC2. In this paper, we describe OpenStack architecture in detail and introduce its...
With the rapid development of modern astronomical observational technology, the processing and analyzing of massive astronomical data bring us an unprecedented challenge. As an effective approach, Visualization Technology (VT) is becoming a hotspot for analyzing massive data. In this paper, in the lights of previous lieratures of visualization technology, we further discuss the possibilities of using...
New Vacuum Solar Telescope (NVST) possesses a world-class solar telescope which observes the sun by high resolution image instruments and multi-wave spectrometer in visible and near infrared bands. NVST has gathered millions of Flexible Image Transport System (FITS) files since it has been for the routine observation and thousands of files are generated in a day. To search efficiently for a subset...
What is a systematic way to efficiently apply a wide spectrum of advanced ML programs to industrial scale problems, using Big Models (up to 100 s of billions of parameters) on Big Data (up to terabytes or petabytes)? Modern parallelization strategies employ fine-grained operations and scheduling beyond the classic bulk-synchronous processing paradigm popularized by MapReduce, or even specialized graph-based...
We live in an increasingly connected world where not only can we open our garage doors with sensors, but from a remote location we can also lock our doors, or turn off our lights. Such convenience and flexibility come with great concerns for privacy and security. In this paper, we study privacy of smart home devices in home residence settings and show how homeowner’s privacy could be compromised via...
With the development of mobile web integration technologies and wireless sensor networks, the interactive activities of human society increasingly rely on the heterogeneous network environment including the communication network, the Internet and sensor networks. This paper tries to apply socially aware computing and data mining to the mobile web application integration technology. It emphasizes understanding...
The research presented in this article proposes an innovative services management infrastructure for e-business services integration. E-business environments are characterised by a variety of services from providers as well as constantly changing demands from requesters (e.g. users). Managing services and providing effective solutions through adequate identification and invocation of services to meet...
The paper presents an adaptive and responsive service framework that integrates context aware techniques with an open source service oriented platform OSGi. The adoption of context aware techniques will allow the proposed service framework to dynamically and effectively manage services resources in response to in-bound tasks identified by the framework. The core services (i.e system services) of the...
Distributed Virtual Environments like online games or 3D virtual worlds have become very popular in the last few years and a more substantial surge in popularity and use is expected. Because of the huge number of users, such environments will undergo a change of infrastructure from a centralized to a decentralized one, making higher demands on consistency issues. This paper addresses consistency problems...
