Autonomous vehicles are an exemplar for forward-looking safety-critical real-time systems where significant computing capacity must be provided within strict size, weight, and power (SWaP) limits. A promising way forward in meeting these needs is to leverage multicore platforms augmented with graphics processing units (GPUs) as accelerators. Such an approach is being strongly advocated by NVIDIA,...
The main challenge of architecting modern industrial control and automation systems (ICASs) is that they need to fulfill quality attributes (QAs) traditional to real-time systems — such as timeliness and predictability — and modern software engineering — such as modularity or reusability. QAs often areconflicting, which entails difficult trade-offs. As a consequence, even the architecture of closely...
Emotion recognition has many useful applications in daily lives. In this paper, we present a potential approach to detect human emotion in real time. For any face detected in camera, we extract the corresponding facial landmarks and examine different kinds of features and models for predicting human emotion. The experiments show that our proposed system can naturally detect human emotion in real time...
3D ball tracking is a critical function in manyapplications such as game and players behavior analysis, andreal time implementation has become increasingly importantfor it can be used for live broadcast and TV contents. To reacha high accuracy, algorithms usually are time consuming due toa large set of calculations which is challenging to meet realtime demanding. This paper proposes multiple commandqueues,...
Studying the TIMELINESS of PERIODIC tasks of real time operating systems available in open source, to determine the reliability and efficiency of the systems for implementing them in suspension control of ground vehicles. We take several operating systems which are open source and are available to the public through GNU license (ex: Linux). The Kernels, which are the building blocks of the operating...
With increasing resolutions the volume of data generated by image processing applications is escalating dramatically. When coupled with real-time performance requirements, reducing energy con- sumption for such a large volume of data is proving challenging.
REDEFINE is a distributed dynamic dataow architecture, designed for exploiting parallelism at various granularities as an embedded system-on-chip (SoC). is paper dwells on the exibility of REDEFINE architecture and its execution model in accelerating real-time applications coupled with a WCET analyzer that computes execution time bounds of real time applications.
Security in Cyber-Physical Systems (CPS) has become a serious concern owing to the rapid adoption of technologies such as plug-and-play connectivity, robotics and remote coordination and control. It is well understood that the performance overhead incurred due to security considerations is rather high, which needs to be captured holistically for a real-time CPS with strict timing budget and hard deadlines...
We use a backstepping technique with time-varying kernels to derive an observer that estimates unknown boundary parameters and the states in 2×2 linear hyperbolic PDEs from sensing anti-collocated with the uncertain parameters. The theory is demonstrated in a simulation.
There exist some real-time solutions for x86 personal computers. Most of them involve adding real-time extensions or modifying kernels to make operating systems be able to run real-time tasks. We provide another real-time solutions for x86 personal computers by proposing a model consisting of a non-real-time operating system for non-real-time tasks, a separated real-time operating system for running...
Inband full-duplex radio transceivers offer enhanced spectral efficiency by transmitting and receiving simultaneously at the same frequency. However, deployment of such systems is challenging due to the inherent self-interference stemming from coupling of the transmit signal to the receiver. Furthermore, to track changes in the time-varying self-interference channel, the process needs to be self-adaptive...
System dependability and real-time requirement have been receiving widespread attention in modern computer systems. Fault-tolerant real-time scheduling provides a method of combining timing requirements and faults tolerance for real-time systems. This paper presents a preliminary study of building a fault-tolerant real-time mechanism for seL4 microkernel. seL4, as the first formally-verified operating...
For investigations of rapidly moving structures in opaque technical devices ultrafast electron beam X-ray computed tomography (CT) scanners are available at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). Currently, measurement data must be initially downloaded after each CT scan from the scanner to a data processing machine. Afterwards, cross-sectional images are reconstructed. This limits the application...
Companies developing and maintaining software-only products like web shops aim for establishing persistent links to their software running in the field. Monitoring data from real usage scenarios allows for a number of improvements in the software life-cycle, such as quick identification and solution of issues, and elicitation of requirements from previously unexpected usage. While the processes of...
This paper presents a componentized TOPPERS/ASP3 (a real-time operating system) time event notification using a plugin feature for the TOPPERS Embedded Component System (TECS). With emerging trends in cyber-physical systems, productivity is becoming a problem, owing to the complexity of such systems. To solve this problem, TECS has been proposed previously. Whereas TECS supports the generation of...
Accurate calculation of a disparity map in real-time is a challenge in computer vision and autonomous applications due to the expensive computation cost. This paper describes a local temporal stereo method, using normalized cross correlation (NCC) as the matching cost function. To increase the performance in terms of speed without degrading the quality, a down sampling of the disparity map in the...

Robust feature tracking is a basic requisite for indoor navigation. The Scale Invariant Features Transform (SIFT) features are invariant to image translation, scaling, rotation, and partially invariant to illumination changes. Therefore, it is widely used for image matching based indoor navigation. However, the implementation of the traditional SIFT algorithm needs excessive computation operations,...
