As industry moves towards many-core chips, networks-on-chip (NoCs) are emerging as the scalable fabric for interconnecting cores. With power now first-order design constraint, early-stage estimation of NoC has become crucially important. ORION was amongst first models released, and since been fairly widely used NoCs. However, when validated against recent prototypes - Intel 80-core Teraflops chip communications core (SCC) we saw significant deviation that can lead to erroneous choices. This...
Two stochastic model predictive control algorithms, which are referred to as distributionally robust proposed in this article for a class of discrete linear systems with unbounded noise. Participially, chance constraints imposed on both the state and control, makes problem more challenging. Inspired by ideas from optimization (DRO), two deterministic convex reformulations tackling constraints. Rigorous computational complexity analysis is carried out compare algorithms existing methods....
This paper studies the three-dimensional (3D) trajectory optimization problem for unmanned aerial vehicle (UAV) aided wireless communication. Existing works mainly rely on kinematic equations UAV's mobility modeling, while its dynamic are usually missing. As a result, planned UAV trajectories piece-wise line segments in general, which may be difficult to implement practice. By leveraging concept of state-space model, control-based design is proposed this paper, takes into account both and...
Computation offloading over fog computing has the potential to improve reliability and reduce latency in future networks. This paper considers a scenario where roadside units (RSUs) are installed for tasks computation nodes including nearby cloud center. To guarantee reliable communication, we formulate first subproblem of power allocation, leverage conditional value-at-risk approach analyze successful transmission probability worse-case channel condition. complete with low latency, second...
Wireless powered communication (WPC) has been considered as one of the key technologies in Internet Things (IoT) applications. In this paper, we study a wireless time-division duplex (TDD) multiuser multiple-input multiple-output (MU-MIMO) system, where base station (BS) its own power supply and all users can harvest radio frequency (RF) energy from BS. We aim to maximize users' information rates by jointly optimizing duration time slots signal covariance matrices BS users. Different...
This paper addresses the event-triggered attitude control problem for spacecraft anti-unwinding reorientation with multiple constraints in presence of external disturbance. Based on a designed novel potential function(PF), new sliding mode controller is proposed to guarantee completeness and Different from existing continuous controller, static dynamic mechanisms, related variable disturbance bound, are then constructed. With schemes, system asymptotic stability, satisfaction action free...
An output feedback stochastic model predictive control (SMPC) is proposed in this paper for a class of linear discrete-time systems, which the uncertainties from external disturbance, measurement noise and initial state estimation error are all considered. Particularly, support sets unbounded distributions not exactly known. Based on distributionally robust optimization (DRO), deterministic convex reformulation derived handling chance constraints. Recursive feasibility convergence algorithm...
A sliding mode controller is proposed for the attitude control of spacecraft reorientation with constraints. By introducing a potential function, novel function designed. With structure uniqueness equilibrium and fixed-time convergence are rigorously proven. Another advantage that feasibility constraints can be proven not only on surface but also outside it. Moreover, singularity issue resolved. Effectiveness method demonstrated by carrying out two numerical simulation.
The emerging distributed satellite cluster network (DSCN) holds great promise in various practical fields, including earth observation, disaster rescue, and tracking of forest fires. In the DSCN environment, it is essential to achieve best data delivery performance by coordinating multi-dimensional heterogeneous dynamic resources. However, real-world applications, distribution long-term arrival not often fully known. Motivated this fact, we propose a distributionally robust two-stage...
To explore the impact of life rules (including individual's habits and patterns, such as diet, sleep, learning styles) on mental health behavioral problems among adolescent youth students after lifting COVID-19 restrictions in Sichuan, China analyze influencing factors rules. An online survey was conducted middle schools, high colleges universities Sichuan Province, China, from December 14, 2022, to February 28, 2023. Demographic information, epidemic-related questions, information were...
Studies suggest that inter-area low-frequency oscillations can be damped with supplementary damping control of large-scale photovoltaic (PV) plants. Multiple-model adaptive (MMAC) is applied as the strategy to deal uncertain variations postdisturbance operating conditions. To reduce scales model bank and damper bank, K-means clustering algorithm used taking modes features for condition clustering, a common designed each cluster. Based on deviation between output dynamic responses actual...
Network-on-chip (NoC) based multiprocessor system-on-chips (MPSoCs) have been proposed as promising architectures to meet modern applications' ever-increasing demands for computing capability under limited power budget. Understanding the behaviors of MPSoC applications is key design MPSoCs tight and performance constraints.
