The ability to recognize emotions in spoken words is central in human communication and social relationships. When studying one's ability to perceive emotions, the standard paradigm is to have listeners choose which one of several emotion words best characterizes linguistically neutral utterances made by actors attempting to portray various emotional states. Usually, generic experiment control software...
Energy monitoring system is based on computer network, automation control and communication technology comprehensive application. To design energy monitoring system should not only in the monitoring data to real-time and accuracy and in maintaining rapid and convenient arrived on the requirements. The design for the above requirements, with centralized management, decentralized control and remote...
This work addresses the challenge of allowing simultaneous and predictable accesses to shared data on multicore systems. We propose a predictable cache coherence protocol, which mandates the use of certain invariants to ensure predictability. In particular, we enforce these invariants by augmenting the classic modify-share-invalid (MSI) protocol with transient coherence states, and minimal architectural...
To reduce the amount of CO2 produced from the personal cars in the world, the parking lot guidance systems are considered to be the solution in shopping malls or department stores in many countries. However, most of the current parking lot systems are located in the parking area of each shopping mall and they cannot show the parking lots information for the driver that are driving on the road. So,...
In this paper we describe CyberVAN, a Cyber Security Virtual Assured Network testbed. CyberVAN enables speedy and flexible setup of high-fidelity cyber security scenarios to evaluate the effectiveness of both novel existing cyber technologies. CyberVAN provides many features needed by cyber security researchers, developers and practitioners alike, and can be used for both verification and validation...
SpaceWire-D is an extension to the SpaceWire protocol that provides deterministic capabilities over existing SpaceWire equipment. The network is divided into segments using a virtual bus abstraction, where a virtual bus consists of a single RMAP initiator, one or more RMAP targets and the SpaceWire links that make up the paths between the initiator and the targets. Time-codes are broadcast periodically...
In this paper we present a proof-of-concept implementation to demonstrate advantages of applying software-defined networking (SDN) to real-time Ethernet (RTE) networks. Potential advantages include the support of arbitrary network topologies, central and dynamic network (re-)configurations, the efficient use of bandwidth, and fast failover mechanisms at network level. To illustrate the advantages...
This paper introduces design of a complete CAN Calibration Protocol (CCP) System, including Electronic Control Unit (ECU) driver, Computer calibration software design and an improvement on transfer mechanism. CCP driver is developed as an independent software component with interfaces compatible with different embedded system. Computer software is developed in Microsoft Visual Studio using API of...
Low-power embedded platforms are widely used in various data collection scenarios to capture physical world phenomena in micro-scale. Given that many applications require long operation times, it is important for nodes to employ various schemes to maximize their lifetime. Within the sensor network research community, schemes such as low-power listening (LPL) and low-power probing (LPP) have been actively...
This paper summarizes packet inspection techniques and platforms in the context of emerging Internet technologies. It explores the capabilities of content-based traffic analyser for software defined networks. Two improvements are proposed to the nDPI packet inspection library to enable it for IoT flows analysis.
The multi-agent approach and technology for distributed scheduling, coordination and control of several UAV in group in order to perform joint tasks in real time was considered. The network-centric multi-agent system for real-time task scheduling for UAV's group was proposed. Two part of sheduling initial scheduling and dynamic rescheduling (task redistributed) were considered. For real-time task...
Aiming at the deficiency in the field of marine engineers training at present, an entire virtual training system for marine engineers has been designed and developed, which is composed of the full mission marine engine room simulator module and three-dimensional virtual marine engine room module, respectively aiming at cultivating the operating ability for marine engine room system and marine engine...
This paper presents the automation of the power distribution system of the Pici Campus of the Federal University of Ceará. The paper aims to present the integration via protocol Open Platform Communications (OPC) of an application program for automatic restoration and a commercial Supervisory Control and Data Acquisition (SCADA). OPC ensures different application programs with proprietary protocols...
Complexity in the real-time embedded software domain has been growing rapidly. The component-based software development approach facilitates the development process of such software systems by dividing a complex system into a number of simpler components. Resource reservation techniques have been widely used for providing resources to real-time software components. In this paper we target real-time...
The Modbus protocol is widely used at the field level, such as building automation and industrial automation. Among existing implementations of the protocol over different communication infrastructures, Modbus TCP offers better scalability and interoperability than Modbus RTU and Modbus CAN, while at the same time, its real-time performance suffers, which limits its adoption in time-critical application...
This paper is about a novel approach of organising non-sequential programs to the benefit of wait-free synchronisation. Other than critical sections, processes never block at entrance to a guarded section although only one process at a time is allowed to pass through. Competing processes are forced into bypass but, if necessary and by using futures, they can synchronise on concurrent state changes...
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...
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...
Due to the increasing bandwidth and timing requirements, next generation communication backbones in cars will most likely base on real-time Ethernet variants that satisfy the demands of the new automotive applications. The upcoming IEEE 802.1Qbv standard shows communication approaches based on coordinated time devision multiple access (TDMA) to be good candidates for providing communication with determinism...
The Ethernet-based diagnosis protocol is widely used in automotive systems. Diagnostic gateways have been developed for seamlessly interconnect with Ethernet based diagnostic protocols and traditional in-vehicle network protocols, such as local interconnect network (LIN), controller area network (CAN), FlexRay. A diagnostic gateway is connected to the Internet and manages the interconnection between...
