Considering the neural signals generated by mechanoreceptors in response to haptic stimuli when contacting virtual objects is essential to display spatial haptic distributions on the skin in virtual reality applications. This study focuses on reproducing the neural activities of Merkel cells, which are known as slowly adapting type-1 mechanoreceptors. The firing activity of these receptors is known to respond to strain energy density (SED). We developed a real-time SED calculation method using a specially designed finite element (FE) model of a fingertip, which features a simplified layer structure of skin and nail. We validated the model by comparing its calculation results with those of a detailed model and a homogeneous model, using reliable FE analysis software. We demonstrated that modeling the layered structure of the skin is effective in improving the reproducibility of the SED distribution at the locations of Merkel cells. © 2025 ieee.

Ensuring deadlines of hard real-time applications in server-based deployments is a challenging problem, particularly if the workload arrives following an arbitrary arrival curve. This work extends the “(M, /K)-firm weakly hard” model to server-based systems, ensuring timely processing of real-time requests to the server. We introduce an admission policy to regulate the remote server workload and prevent deadline misses while attempting to admit more requests than the minimum required, when possible. We guarantee the weakly hard constraints through optimal resource allocation and server confiauration.

Drunk driving continues to be a substantial public health issue, leading to a multitude of accidents and deaths on a global scale. Conventional techniques for identifying drunk driving, such as breathalyzers and field sobriety tests, tend to be reactive rather than proactive. This paper surveys the existing methods for detecting drunk driving to enhance traffic safety. The technologies studied can proactively detect impaired driving behaviors by combining machine learning (ML) approaches with real-time data processing. The study outlines various classifications based on measured metrics and driving behavior. © 2024 ieee.

Genome sequencing has evolved from Sanger to advanced third-generation technologies, yet challenges such as limited read lengths and high costs remain. This paper introduces Fourier-LSTM, a hardware-efficient block integrating Fourier transformations with Long Short-Term Memory (LSTM) networks. This approach enhances handling long repetitive sequences and structural variations to improve nanopore sequencing accuracy. Notably, deploying Fourier-LSTM on the embedded RK3588 device significantly reduces power consumption and costs, making it ideal for real-time, portable genomic applications. © 2024 ieee.

In deflection-based Network-on-Chips (NoC), when several flits entering a router contend for the same output port, one of the flit is routed to the desired output and the others are deflected to alternatives outputs. The approach reduces power consumption and silicon footprint in comparison to virtual-channels (VCs) based solutions. However, due to the non-deterministic number of deflections that flits may suffer while traversing the network, flits may be received in an out-of-order fashion at their destinations. In this work, we present IPDeN, a novel deflection-based NoC that ensures in-order flit delivery. To avoid the use of costly reordering mechanisms at the destination of each communication flow, we propose a solution based on a single small buffer added to each router to prevents flits from over taking other flits belonging to the same communication flow. We also develop a worst-case traversal time (WCTT) analysis for packets transmitted over IPDeN. We implemented IPDeN in Verilog and synthesized it for an FPGA platform. We show that a router of IPDeN requires approximate to 3-times less hardware resources than routers that use VCs. Experimental results shown that the worst-case and average packets communication time is reduced in comparison to the state-of-the-art.

Do Not Overpay for Fault Tolerance! 27

Do Not Overpay for Fault Tolerance!

In this paper, we argue that distributed real-time and embedded systems sometimes "overpay" for fault tolerance, by using a protocol that is more powerful than what is actually needed, or by failing to take advantage of unique features in these systems. As a result, these systems sometimes perform more computation or communication than is strictly necessary, or they can be unnecessarily complex, and thus more difficult to analyze. We take a look at the design space for two common problems, broadcast and consensus, and we show that, in a number of scenarios that would be common in real-time systems, these problems have trivial solutions. We then examine two solutions from the literature and propose alternatives that are substantially simpler, less expensive, and more reliable.

The protection of original achievements including patents and copyrights is a significant and critical issue in today's knowledge-driven economy. In this article, we propose and develop a blockchain service architecture to enhance information traceability and protection effectiveness. Our proposed service architecture is enabled by the core functionalities of blockchain technology including distributed data storage, peer-to-peer transmission, consensus mechanisms, and encryption algorithms. Through this blockchain-based traceability system, we can record, secure, validate, and track original achievements' registrations and other related transactions. The results of our simulation experiments further validate the effectiveness and robustness of the proposed traceability system design. Our experimental analysis shows that the proposed blockchain-based design can effectively enhance original achievements traceability with an embedded automatic incentive rewarding mechanism for both the creation and protection of original achievements. Moreover, our performance analysis and comparative analysis show that the proposed method has more advantages over several other methods. While our study provides an effective solution to address the existing challenges in intellectual property rights and achievements patents protection, the breadth of the blockchain concept and its applications require nuanced investigations in many different contexts. Thus, the proposed blockchain-based traceability system highlights the potential for broader applications of this disruptive technology in many other domains.

This paper presents a machine-learning study for solar inverter power regulation in a remote microgrid. Machine learning models for active and reactive power control are respectively trained using an ensemble learning method. Then, unlike conventional schemes that make inferences on a central server in the far-end control center, the proposed scheme deploys the trained models on an embedded edge-computing device near the inverter to reduce the communication delay. Experiments on a real embedded device achieve matched results as on the desktop PC, with about 0.1ms time cost for each inference input. © 2024 ieee.

As the computing landscape evolves, system designers continue to explore design methodologies that leverage increased levels of heterogeneity to push performance within limited size, weight, power, and cost budgets. One such methodology is to build Domain-Specific System on Chips (DSSoCs) that promise increased productivity through narrowed scope of their target application domain. In previous works, we have proposed CEDR, an open source, unified compilation and runtime framework for DSSoC architectures that allows applications, scheduling heuristics, and accelerators to be co-designed in a cohesive manner that maximizes system performance. In this work, we present changes to the application development workflow that enable a more productive and expressive API-based programming methodology. These changes allow for more rapid integration of new applications without sacrificing application performance. Towards the design of heterogeneous SoCs with rich set of accelerators, in this study we experimentally study the impact of increase in workload complexity and growth in the pool of compute resources on execution time of dynamically arriving workloads composed of real-life applications executed over architectures emulated on Xilinx ZCU102 MPSoC and Nvidia Jetson AGX Xavier. We expand CEDR into the application domain of autonomous vehicles, and we find that API-based CEDR achieves a runtime overhead reduction of 19.5% with respect to the original CEDR.
