CRYSTALS-Kyber has been standardized as the only key-encapsulation mechanism (KEM) scheme by NIST to withstand attacks large-scale quantum computers. However, side-channel (SCAs) on its implementation are still needed be well considered for upcoming migration. In this brief, we propose a secure and efficient hardware Kyber incorporating novel compact shuffling architecture. First of all, modify Fisher-Yates shuffle make it more hardware-friendly. We then design an optimized architecture...

A combined kinematic/torque control law is developed by using a backstepping design approach for nonholonomic mobile robot with two driving wheels mounted on the same axis to track reference trajectory. The auxiliary velocity inputs are designed kinematic steering system make posture error asymptotically stable. Next, computed-torque controller such that robot's velocities converge given in an optimal manner converting tracking problem into regulation whereby uncertainties dynamics of robots...

This paper addresses both the model selection (i.e., estimating number of clusters K) and subspace clustering problems in a unified model. The real data always distribute on union low-dimensional sub-manifolds which are embedded high-dimensional ambient space. In this regard, state-of-the-art approaches firstly learn affinity among samples, followed by spectral to generate segmentation. However, arguably, intrinsic geometrical structures samples rarely considered optimization process. paper,...

In recent years, Rapid development had been made by brain computer interfaces(BCI) technology, providing a new way of communication between people and the outside world. Researchers proposed varied BCI based methods to control Robotic arms, exoskeletons, robotic cars for locomotion. However, most contemporary systems were poor in human-computer interaction user experience. For example, mind-controlled vehicles, controllers would not know location vehicle real time scene. On other hand,...

It is desirable that the nodes exhibit fail-silent behavior when designing distributed fault-tolerant systems. Bus Guardian (BG) adopted to enforce fail-silence property of node in FlexRay communication system. However, BG effective only static segment while dynamic it does not provide any protection. Therefore, a novel proposed this paper. The mechanisms are presented along with architecture necessary for implementing technique. Mathematical analysis results show can effectively entire cycle.

The visually servoed trajectory tracking of quadrotors has attracted many academic researchers over the past decade, and numerous controllers are proposed for this challenging problem. controller in paper follows Position Based Visual Servoing (PBVS) paradigm. Most PBVS controllers, if not all, implemented assuming that position quadrotor been accurately recovered with an independent estimator. Therefore rigorous stability cannot be promised due to separation principle does hold general...

FlexRay is a communication system whose development was driven explicitly by the new needs of future in-car control applications. However, as far babbling idiot avoidance concerned, does not provide satisfactory solution. Therefore, novel Bus Guardian (BG) designed to avoid failure in systems this paper. To minimize affects common mode between BG and associated node, operates with an independent clock synchronization process. The supervision algorithm presented performance evaluation done...

Previous studies showed that facial appearance is an important phenotypic indicator of human diseases or biological conditions. Recent advancements in deep learning have shown great potential image analysis, including health status assessments. However, prior methods mainly focused on single modality analysis either the 2D texture images 3D meshes, which are limited their ability to fully capture relationships between biometric measurements and diseases. To address these issues, we propose a...

Experiments results show way, correlation-based number sample data for by...

The traditional system controller in symmetric multi-processors (SMP) controls the memory, so it is suitable for shared memory programming model. With emergence of processors which integrate controllers, seems less important than before. However, since resides center a computer system, acts as an artery directly connects to and high-speed IO devices. Thus making full use its position advantage can no doubt gain performance enhancement. By now, message passing model has dominated high...
