Dynamic power-gating for leakage power reduction in FPGAs Research Article

Hadi JAHANIRAD,h.jahanirad@uok.ac.ir

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 582-598 doi: 10.1631/FITEE.2200084

Abstract: In battery-restricted applications such as handheld electronics systems, low-power FPGAs are in greatalmost equals dynamic power in modern integrated circuit technologies, so the reduction of leads toWe propose a power-efficient architecture for static random access memory (SRAM) based FPGAs, in whichThe proposed low-leakage FPGA architecture is compared with state-of-the-art architectures by implementingMoreover, the total power consumption (leakage+dynamic power consumption) is reduced by more than 15%

Numerical and experimental analyses of methane leakage in shield tunnel

Frontiers of Structural and Civil Engineering   Pages 1011-1020 doi: 10.1007/s11709-023-0956-z

Abstract: Tunnels constructed in gas-bearing strata are affected by the potential leakage of harmful gases, suchmethane emission was diluted, and the methane accumulation was only observed in the area near the methane leakageIn addition, laboratory tests on methane leakage through segment joints were performed.The results show that the leakage process can be divided into “rapid leakage” and “slight leakage”, dependingon the leakage pressure and the state of joint deformation.

Engineering 2021, Volume 7, Issue 6,   Pages 758-776 doi: 10.1016/j.eng.2020.08.026

Abstract:

Liquid leakage from pipelines is a critical issue in large-scale process plants.Recently, the use of infrared (IR) cameras was found to be a promising approach for leakage detectionThe k-nearest neighbor algorithm is used to classify the blocks as normal (without leakage)or anomalous (with leakage).The proposed method has high accuracy and a reasonable detection time for leakage detection.
