The TMO (time-triggered message-triggered object) model is a well-known real-time object model for distributed timeliness computing. In a couple of years ago, we developed a Linux-based real-time kernel, named TMO-Linux, supporting deadline driven executions of TMO's. TMO-Linux and its distributed IPC subsystem have been used well in developing networked(More)
In this paper, we propose the mouse to control a computer with a shoe called IPFM: intelligent pressure foot-mouse. It is mainly composed of five parts including pressure sensor (FSR) embedded in a shoe, 3-axis acceleration sensor in front of shoe to measure a foot motion, computing module (FPGA), wireless communication module and visualization module(More)
The Linux-based legacy server systems are configured and used with software RAID to improve the performance of the disk I/O. However, the problem is that the current Linux kernel and software RAID are difficult to optimize the high-performance block I/O because it is designed to be optimized for low-speed devices. Therefore, we propose the efficient method(More)
The Linux-based legacy server systems are configured and used with software RAID to improve the performance of the disk I/O. Server systems requiring high performance prefer a special SSD that connects directly with the PCI-express bus to the SATA interface. However, the problem is that the current Linux kernel and software RAID are difficult to optimize(More)
Since the introduction of big data, numerous researches aiming to improve the accuracy and speed of data processing has been conducted. Many platforms that can process real-time data were developed for this purpose. Most standard data processing platforms used Spark Streaming as data analysis layer. However, its limitation in performance calls for a better(More)
