In this research, we attempt to develop for artistic music loop performance on a de facto standard digital DJ system with TouchOSC. Through the analysis on the functions and UI of de facto DJ software and controllers, the 4 shortage of functions for artistic music loop performance were found. Therefore, we built the remote controller system by TouchOSC. It enables to control the complicated music...
ITER control system model (ICM) is a currently developed simulation platform for control, data access, and communication (CODAC), which is a central control system responsible for integrating and controlling all plant systems of ITER. ICM is a large-scale implementation of CODAC that follows hardware and software standards but does not have any interfaces to other physical components of ITER. ICM...
Clock synchronization is an important issue in wired and wireless networks as a common time basis is essential for coordinated activities of nodes in distributed systems. Typical applications demanding precise synchronization are Industrial Internet scenarios having real-time constraints, Wireless Sensor Networks (WSNs) where the nodes communicate only for a short period and can sleep the remaining...
A framework to integrate different artificial intelligence and machine learning algorithms is combined with an execution framework to create a powerful cloud computing system development platform. By providing an execution framework and control software that is native to cloud architectures and supports interactivity and time synchronization, the true utility of cloud computing and "big data...
The article describes some of the features of the servo amplifier, developed in the NRU “MPEI” for use in multi-axis high-precision materials processing. Simplified structure of servo amplifier and some of the key components of servo drive digital control system are presented. Two ways of multi-axes control are compared: using the RS-232 interface and digital inputs/outputs, and using the CANopen...
High performance and high power efficiency are two mandatory constraints for multi-core systems in order to successfully handle the most recent applications in several fields, e.g. image processing and communication standards. Nowadays, hardware accelerators are often used along with several processing cores to achieve the desired performance while keeping high power efficiency. However, such systems...
Nowadays, the average users owns two or more Web-enabled devices (smart phones, personal computers and tablets), while more are coming: watches, cars, glasses. While responsive Web applications can adapt to the specific device (e.g., screen size or input method) on which they are deployed, they only provide limited support when one user connects from more than one device at the same time. In this...
Nowadays concurrent programming is in large demand. The inherent support for concurrency is therefore increasingly important in programming languages. As for C++, an abundance of standard concurrency constructs have been supported since C++11. However, to date there is little work investigating how these constructs are actually used in developing real software. In this paper, we perform an empirical...
Due to the high complexity in software hierarchy and the shared queue & lock mechanism for synchronized access, existing I/O stack for remote target access in FCoE-based SAN storage becomes a performance bottleneck, thus leading to a high I/O overhead and limited I/O scalability in multi-core servers. For scalable performance, existing works focus on improving the efficiency of lock algorithm...
The requirements, functionality, and consequently also the complexity of software used in the automotive industry has continuously been increasing over the last decades. To cope with this development, main car manufacturing companies and automotive suppliers established the AUTOSAR partnership back in 2003. Its main objective is to reduce development costs and to enhance cooperation between different...
The design of avionic systems is a complex engineering activity. The iterative integration approach helps in controlling the complexity of such activity. On the other hand, using such approach to design evolving systems requires the reconfiguration of scheduling parameters of already integrated parts. This reconfiguration results in a recertification process having a cost that depends on the criticality...
This work investigates the composition of interdependent software components on a shared platform from a timing perspective. Because we consider software components for vehicular systems, which are often sensitive to timing, the individual components and the composed system require timing analysis. In order to support independent development of components, the real-time systems community proposed...
For a distributed embedded system (DES) to operate continuously in a dynamic environment, it must be flexible and highly reliable. This applies in particular to its communication subsystem. The Flexible Time-Triggered Replicated Star for Ethernet (FTTRS) aims at providing such a subsystem by means of a highly-reliable switched-Ethernet architecture based on the Flexible Time-Triggered paradigm (FTT),...
Real-time Ethernet variants are expected to build the future communication infrastructure in cars. First camera based driver assistance functions will communicate using IEEE 802.1 AVBs credit-based shaping. But for the strict timing requirements of automotive control-traffic, AVBs current timing guarantees are insufficient. The upcoming IEEE 802.1Qbv standard proposes synchronous time-triggered traffic...
A new steering strategy is used to monitor and control UTC(NTSC) in this paper. A new atomic time scale TA for real-time monitoring UTC(NTSC) is shown firstly, then the New steering strategy and software proceeding are discussed afterwards. Finally, the results of real steering are discussed, and a successful improvement in steering strategy is showed.
This paper analyzes the interoperability issues of the information exchange among essential software applications that enable University electronic services. The analysis of the existing standards shows that there is no fully defined compatibility for these software solutions, which motivated us to conduct a research in order to detect and describe the interoperability challenges of creating a fully...
Over past few years, there has been a huge advancement in terms of Learning Management System (LMS) and online education. Behind this growth, the major reasons are the availability of open source LMS and their ease of customization. This paper proposes some new features for these pre-existing LMS, especially Moodle, such that the same LMS could also function as College / University Management System...
This paper presents an industry experience and research-based analysis of issues that the deployment of PTP as a service is facing in the finance industry, based on real life examples from a global stock exchange operator. It aims to summarise over three years of author's experience with deploying PTP, highlighting the most common problems encountered: standard specific, implementation specific and...
As software development becomes an increasingly collaborative effort, traditional development tools have to be extended to support seamless collaboration while minimizing the chances of conflicts. This paper describes Cloud Studio, a collaboration framework that integrates a fine-grained software configuration management model and a real-time awareness system. Cloud Studio's configuration management...
IEEE1588 standard Precision Time Protocol (PTP) is proposed to solve the high precision time synchronization problems in the application field. This technique will be ported to LINUX + inhibits PTP program POWERPC platform, makes it with the support of hardware timestamp of 100 ns level timing accuracy. We tested and analyzed software and hardware timestamp that affects the performance of GPS clock...
