The active simultaneously transmitting and reflecting surface (STARS) has been proposed as a complement of passive STARS (PSTARS) to inhibit the double path-loss. This paper applies the active STARS (ASTARS) to aid in non-orthogonal multiple access (NOMA) covert communications over cascaded rice fading channels, where two wardens are located on the opposite sides of ASTARS to monitor the transmission information. More specifically, we derive approximate expressions for detection error probability of two wardens. The optimal detection threshold and minimum detection error probability are presented in the worst covert scenarios. The covert transmission rate expressions for a coupe of covert users are further deduced by taking into account imperfect/perfect successive interference cancellation. The experimental simulation results are presented to confirm that: 1) The detection error probability of ASTARS-NOMA networks is superior to that of ASTARS assisted-orthogonal multiple access (ASTARS-OMA) and PSTARS aided NOMA networks;2) As the number of active elements increases, the covert transmission rates of ASTARS-NOMA networks become larger relative to ASTARS-OMA;and 3) ASTARS-NOMA has ability to provide the enhanced system throughput in delay-tolerant transmission mode. © 2025 IEEE.

Parallel and Distributed Methods for Image Processing

作者： Moore, Michael S. Sztipanovitz, Janos Karsai, Gabor Nichols, James A. Vanderbilt University Measurement and Computing Systems Laboratory 400 24th Ave S. Nashville TN 37235 United States

In this paper, it is shown that, through the use of model- integrated program synthesis (MIPS), parallel real-time implementations of image processing data flows can be synthesized from high level graphical specifications. The complex details in inherent to parallel and real-time software development become transparent to the programmer, enabling the cost-effective exploitation of parallel hardware for building more flexible and powerful real-time imaging systems. The model integrated real-time image processing system (MIRTIS) is presented as an example. MIRTIS employs the multigraph architecture (MGA), a framework and set of tools for building MIPS systems, to generate parallel real-time image processing software which runs under the control of a parallel run-time kernel on a network of Texas Instruments TMS320C40 DSPs (C40s). The MIRTIS models contain graphical declarations of the image processing computations to be performed, the available hardware resources, and the timing constraints of the application. The MIRTIS model interpreter performs the parallelization, scaling, and mapping of the computations to the resources automatically or determines that the timing constraints cannot be met with the available resources. MIRTIS is a clear example of how parallel real-time image processing systems can be built which are (1) cost-effectively programmable, (2) flexible, (3) scalable, and (4) built from commercial off-the-shelf (COTS) components. ©2005 Copyright SPIE - The International Society for Optical Engineering.

Supervisory control reconfiguration has been paid more attention due to its capacity of handling the uncertainties including resource failures, capability degradation, and task changes in discrete event systems. However, the robustness of closed-loop systems in response to some specification changes was not addressed in the prior studies. This paper presents a reconfiguration method based on Petri nets and integer programming for supervisory control of resource allocation systems with changeable resource allocation relationships (control specifications). First, we propose a reconfiguration mechanism. It updates the P-invariant-based supervisor and evolves the state of the closed-loop system. The latter adapts to the certain changes in specifications by the self-regulation of the closed-loop system's state. It utilizes fully the robustness in a closed-loop system and avoids unnecessary modification of a supervisor. Then, a reconfiguration model with robustness analysis is proposed based on integer programming. By using it, a firing sequence of transitions as a serial of reconfiguration actions can be found. The execution of the sequence implements the state evolution of a closed-loop system. There is no need for making additional efforts to analyze state reachability of the system, since the firability condition of transitions is incorporated into the model. Finally, the method is illustrated through an example of a hospital emergency service system. © 2013 IEEE.

We describe a programming environment which is being developed for the automatic generation of parallel image processing applications. Through the use of model-based software synthesis, we transparently create large grained data parallel applications which can be executed on arbitrary processor networks. The high-level abstractions provided by the modeling paradigm isolates the user from the complexity of the underlying implementation, allowing developers with little or no experience in parallel programming to rapidly create parallel applications. The data parallel modeling facilities perform the same tasks as the data alignment and distribution compiler directives of High Performance Fortran and the aggregate objects of pC++. However, we have found that by introducing the parallelism on the system level, instead of in the algorithm, we can use traditional compilers and leave the application specific code unchanged. This allows us to take advantage of existing well developed image processing code libraries. Here we describe a system which generates data parallel versions of applications created in Khoros, the popular image processing package developed by the University of New Mexico. This system retains the best qualities of Khoros: its interactive and experimental nature, and its visual interface, but adds the capability for automatically generating much higher performance parallel implementations when needed. This system demonstrate the suitability of the model-based approach for developing parallel imaging software.< >

Among the most significant technological developments of the last two decades has been the proliferation of computer-based systems (CBSs). These systems embed software to create "smart" tools and products. In CBSs, functional, performance and reliability requirements mandate a tight integration of information processing and physical processes. Embedded information technology is critical to overall system performance. CBSs include a wide range of applications, such as computer integrated manufacturing (CIM) systems, space systems, computerized vehicles, appliances, consumer electronics equipment, and a wide variety of systems in health care, transportation defense, communication, and power generation and distribution.

In a competitive market, manufacturing enterprises require a process of continuous on-going improvement in order to maintain and enhance productivity and a competitive edge. The use of Information systems (IS) has been increasingly playing a critical role in any such engineering process. The primary drivers are efficiency and quality increase through automation facilitation of better business processes and improved decision making. The engineering process involves use of an IS for collection of relevant production data, visualization, analysis and decision making. Many problems and issues relating to the design, development, integration, evolution and maintenance of ISs in large-scale and complex plants have become apparent which are not adequately addressed by the traditional Process Monitoring and Control (PM&C) systems. Model Integrated computing (MIC) offers a feasible approach towards providing cost-effective development, integration, evolution and maintenance of ISs through the extensive use of models during the life cycle. This paper describes the application of MIC in the engineering process for improving productivity in the context of discrete manufacturing operations at Saturn. The Saturn Site Production Flow (SSPF) system is a client-server application, designed to provide an integrated problem-solving environment. It presents consistent and pertinent information, provides analysis and decision support services that are needed for informed decision making by the team members and leaders within Saturn.

With the advancement of industrial automation and artificial intelligence technology, unmanned port autonomy has gained increasing attention. Port automatic driving technology is a critical component of unmanned autonomous systems, enabling rubber tire gantry cranes (RTGs) to autonomously navigate by detecting port lanes and implementing control commands. In this study, a deep learning-based method is proposed for detecting port lanes in complex port scenes. The method employs the Inception module and attention mechanism to enhance lane feature extraction, and a structural loss is introduced to explicitly constrain the detection results and incorporate the prior characteristics of port lanes. A novel Mixed Feature Attention Network (MFANet) is proposed to implement the method for port lane detection. Experimental results demonstrate that MFANet effectively improves the accuracy of port lane detection while maintaining high computational efficiency. Furthermore, the performance of MFANet is evaluated in a real-world application scenario. © 2023 Technical Committee on Control Theory, Chinese Association of Automation.

The deep crate grasping problem is a major challenge for manipulator in industrial applications. In order to solve the issue of deep crate grasping and ensure the path quality of the algorithm, this paper proposes a new hybrid obstacle avoidance planning algorithm based on goal-biased rapidly exploring random tree and improved artificial potential field (RRT-APF). Initially, the algorithm strategizes an efficient trajectory for the working element within the operational area. Subsequently, it dissects this trajectory through sampling, creating a sequence of sub-target points. These points serve as the basis for obstacle avoidance planning within the manipulator's configuration space, mitigating planning complexities. Moreover, the RRT algorithm is employed to address the challenge of local optima within the artificial potential field method. The stochastic nature of the RRT algorithm plays a crucial role in enabling the APF algorithm to break free from local optima. Ultimately, the efficacy of the algorithm is demonstrated through the planning of a path for obstacle avoidance on the DOBOT CR5 manipulator using MATLAB. © 2023 IEEE.

With the rapid development of deep learning, it has been widely applied in fields such as computer vision, natural language processing, and robotics. Despite the superior performance of deep learning in object detection, most industrial vision robots still rely on traditional object detection methods due to computational constraints of robot controllers. In order to improve the performance of object detection for vision robots, a lightweight 3D object detection network based on You Only Look Once version 5 (YOLOv5) is proposed for satisfying industrial production. YOLOv5 work to efficiently object detection using deep convolutional networks. In terms of model deployment, we adopt a novel OpenVINO-based model deployment approach. The OpenVINO framework significantly enhances the inference speed of models by model optimization and compression. Our model achieves a 70% reduction in inference time compared to the baseline model on CPU. The effectiveness of the proposed method is demonstrated through experiments. © 2023 IEEE.
