Real-time color quantization requires high performances and high configurability. Self-organizing maps (SOMs) are very suited as color quantizers. However, widely used software SOM quantizers are flexible with limited performances, whereas the hardware counterparts lack in flexibility. In this work, we propose a flexible and adaptable real-time hardware implementation of a SOM map applied to color...
A simple, rugged and accurate Flight Profile Simulator (FPS) for launch vehicle hardware and software real-time testing is proposed in this paper. The launch vehicle onboard system is a MIL-STD-1553B based configuration with Onboard Computer (OBC) as Bus Controller (BC) and Navigation, Sequencing and Control subsystems as Remote Terminals (RT). The simulator acts as another RT on the 1553B bus and...
Electricity generation from renewable sources is radically increasing in an effort to achieve the Sustainable Energy for All objective of doubling the share of renewable energy in the global energy mix by 2030. However, the current grid has difficulty accommodating variable power sources like wind and solar. To accelerate the integration of renewable distributed power generation there is a need for...
Highly distributed applications dominate today's software industry posing new challenges for novel software architectures capable of supporting real time processing and analytics. The proposed framework, so called REAXICS, is motivated by the fact that the demand for aggregating current and past big data streams requires new software methodologies, platforms and services. The proposed framework is...
Reducing as much as possible the rate of software crashes is crucial especially in medical applications. In this paper, we make the assumption that crashes result from the user workflow, that is to say the sequence of user actions. Our objective is thus to identify root causes of crashes and to anticipate them in real-time, based on the analysis of the sequences of user actions. For these purposes,...
Summarized the mainly algorithms of terrain three-dimensional visualization in virtual reality, for the large-scale terrain data organization in three-dimensional virtual war zone simulation, analyzed the characteristic of change of scene, according to motion regulation and idea of layer and block, presented the organize principle of external static data and terrain blocks index regulation, for the...
An efficient photoplethysmography imaging system and advanced algorithm for continuous monitoring of skin microcirculation was developed. The system comprises compact device and computer with software for visualizing of skin blood volume changes. The software is able to process high-resolution microcirculation amplitude maps in real-time. It was tested in clinical environment during the regional anesthesia...
Real-time monitoring of physiological data can reduce the likelihood of injury in noncombat military personnel and first-responders. MIT Lincoln Laboratory is developing a tactical Real-Time Physiological Status Monitoring (RT-PSM) system architecture and reference implementation named OBAN (Open Body Area Network), the purpose of which is to provide an open, government-owned framework for integrating...
The electrical grid uses intelligent electronic devices, communication technologies, distributed energy resources, energy storage, and smart appliances in order to make smart grid which provides reliability and power quality. In smart grid, Advanced Metering Infrastructure (AMI) provides a two-way communication system between utilities and smart meters, as well as the ability to modify consumer demand...
Current industrial systems need to interact with the surrounding environment in order to provide more efficiency. In such systems, used software applications must be strong enough to answer run-time needs. Context-aware applications seem to be an appropriate solution that can satisfy adaptation to the continuous changes. Safe reconfigurations require the respect of tasks deadlines and the avoidance...
The growing need of Disaster management requires some specialties in sophisticated technologies. Navigating an Unmanned Aerial Vehicle (UAV) in an unknown indoor environment is a complex task. This work tries to implement an autonomous system, which navigates the Low-cost Quadcopter with an on-board computer, sensors and Ground station which carries out a spatially consistent probabilistic model for...
Securing critical systems such as Cyber-Physical Systems (CPS) is an important feature especially when it comes to critical transmitted data in a real-time environment. At the same time, the implementation of security counter-measures in such systems may impact transmission delays of critical tasks. For this reason selecting proper security mechanisms in such critical systems is an important issue...
Collaboration is a huge part of modern software development. Yet most tools used in software development are aimed for single user instances. To support collaborative software practices, researchers and practitioners have presented several tools. The existing tools support collaboration either through distributed version control systems or through client/server-based concurrent text editors. Distributed...
This paper deals with the real-time scheduling in a reconfigurable multi-core platform powered by a rechargeable battery. A reconfiguration scenario is defined as an operation that allows the addition-removal-modification of tasks which may result in timing unfeasibility. Such a system may face several scenarios: i) increased power consumption that, in the worst case, may surpass the available energy...
The issues considered in this paper are related to the development of a variety of topics of information systems for biomedical data processing. This topic is relevant in connection with the continuing need to create of multi-parameter vital sign databases. In addition, modern world trends in the development of big data collecting and processing information systems add some relevance to this work...
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...
A real-time simulator is an essential tool for swiftly designing and verifying embedded time-sensitive and/or real-time applications in both academia and industry. An FPGA-based wireless extensible hardware-in-the-loop (WEX-HIL) real-time simulator was developed for designing subsystems of an electrical vehicle (EV). The WEX-HIL platform is capable of providing a design and test environment of virtual...
Since 2011, we have developed and deployed a standalone Voice-Interactive Digital Signage System to provide useful university information to users at the Nagoya Institute of Technology. This system comprises MMDAgent, a software toolkit to realize voice interaction with 3-D character named "Mei". An important shortcoming is that this system's ability is limited because it lacks a network...
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...
