We demonstrate an early stage of our prototypical development of an earthquake early warning system based on Apple's MacBook computers. This system, called MacSeisApp, utilizes the Sudden Motion Sensors in MacBooks to detect seismic activities. It is inspired by an existing application called SeisMac, which turns a MacBook computer into a seismograph. MacSeisApp expands on SeisMac by using Apple's...
Distributed shared memory(DSM) is an implementation of the shared memory model in distributed systems. Software-defined networking (SDN), can be effectively exploited to improve the performance of DSM. In this research, we propose an SDN-based distributed shared memory architecture. This architecture improves distributed applications by tuning network transmission and offloading functionality to the...
Technology upgrades bring about the need for fielded ATLAS-based environments to expand tests to include modern high speed digital systems. The ATLAS test language does not contain innate capability to describe new tests, so TPS developers use NAM or FEP constructs as the mechanism to communicate with an external system. An external system, such as a self-contained, fully-integrated instruments within...
AMISR is a modular, mobile, UHF radar facility used by scientists and students from around the world to conduct studies of the upper atmosphere and to observe space weather events. SRI International, under a grant from the National Science Foundation, is leading the collaborative effort in the development and operation of AMISR. The novel modular configuration allows for relocating the radar to study...
The aim of autonomic computing is to realize self - management of complex IT systems, which makes systems own the ability of self-configuration, self-recovering, self-optimizing and self-protecting. The aim of cloud computing is to realize the use of resources on demand in distributed environment. But the problem of how to build an autonomic computing model for cloud computing environment has not...
This paper introduces the Calq system for web-based signal processing experiments. The theory is that this system can perform several simple to moderate operations in a reasonably small amount of time on a modern computer running a web-browser. A set of test programs include programming constructs like loops and conditional statements, but also use convolution and plotting. Each test program is tested...
With the continuous development and applications of the computer technology and network technology, the traditional laboratory was in virtue of this powerful tool of modern information technology to continuously reform and innovation, development and improvement. This paper describes a idea of network architecture in university laboratory in order to realize circuit experiments to achieve the network...
With the development of electronic information, the aerial digital image updating is more frequent and the data is more mass, and the traditional method of data processing based on serial computing is difficult to meet the needs of high production efficiency and the quick updating of mass data. For improving the efficiency of data processing, the computing must be parallel. The paper discusses the...
With the introduction of parallel video distribution architecture, the problem of server capacity in a high-demand/high data volume transfer environment is solved with an approach of distributed signal processing and rendering thus reducing the overall load on a single machine (server) and improving the overall solution performance. This paper reviews three parallel video distribution approaches (Proxy-At-Server,...
