The finite-time dissipative control problem of time-delay T-S fuzzy singular systems was studied to address the instability and poor system performance caused by time delay in controlsystems. Using Lyapunov stability theory, finite-time theory, matrix scaling theory and linear matrix inequality, A sufficient condition was provided to ensure that the closed-loop system is bounded in -finite time and meets the dissipative performance index, Obtained the design method of the controller, The proposed method can maintain the system state within a predetermined range for a limited time, Numerical examples demonstrate the effectiveness and feasibility of the proposed method.

Green hydrogen production from renewable energy sources using water electrolysis has recently attracted a significant attention to replace fossil fuel. Yet, improving the performance of green hydrogen production plants (GHPPs) and reducing the cost of hydrogen production require developing the necessary engineering design tools. This paper proposes a novel mathematical formulation to optimize the design of Alkaline electrolysis (AE) based GHPPs, where the objective is to minimize the levelized cost of hydrogen. The developed formulation concurrently determines the optimal sizing of the GHPP components (AE, power converter, and compressor), and the optimal internal parameters of the AE (operating pressures, temperature, effective area, separator thickness, and electrolyte concentration). The formulation takes into account the safety constraint on the limit of the hydrogen crossover in AE. Simulation results indicate that various input power profiles from renewable energy resources have a significant impact on the optimal internal parameters of the AE, specifically influencing the operating pressure and electrolyte concentration. This finding proves the significance of incorporating the optimization of the AE internal parameters as control variables in the design of GHPPs.

Taskflow tackles the long-standing question: How can we make it easier for developers to program parallel and heterogeneous computer-aideddesign (CAD) applications with high performance and simultaneous high productivity? Taskflow introduces a new powerful task graph programming model to assist developers in the implementation of parallel and heterogeneous algorithms with complex control flow. We develop an efficient system runtime to solve many of the new scheduling challenges arising out of our models and optimize the performance across latency, energy efficiency, and throughput. Taskflow has demonstrated promising performance on both micro-benchmarks and real-world applications. As an example, Taskflow solved a large-scale circuit placement problem up to 17% faster, with 1.3x fewer memory, 2.1x less power consumption, and 2.9x higher throughput than two industrial-strength systems, oneTBB and StarPU, on a machine of 40 CPUs and 4 GPUs.
