The Development Situation, Future and Counter Measures of Remanufacturing Industry in China

Wen-qiang Liu,Jun-yuan Mo,Cheng-kui Gu

Frontiers of Engineering Management 2016, Volume 3, Issue 2,   Pages 123-131 doi: 10.15302/J-FEM-2016021

Abstract: Currently, resource supply and demand contradiction, and over-loaded environment capacity have become a bottleneck for sustainable economic development in China. Electro-mechanical products are approaching a peak of obsolescence, and massive abandoned electro-mechanical products are causing severe environmental pollution, huge waste of resources and potential safety hazard. Remanufacturing is repairing or modifying worn mechanical products using high-tech method, which buffers the contradiction between wasting and shortage of resources, and brings industry towards a comprehensive utilization of resource and environmental protection. As a new strategic industry, remanufacturing, which is highly coherent with the development strategy of the circular economy, is still in its infancy in China. This paper analyzes the developmental trends and problems of the remanufacturing industry in China, and proposes promoting measures based on the engineering practices of remanufacturing.

An efficient counter-based Wallace-tree multiplier with a hybrid full adder core for image blending Research Articles

Ayoub SADEGHI, Nabiollah SHIRI, Mahmood RAFIEE, Mahsa TAHGHIGH

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6,   Pages 950-965 doi: 10.1631/FITEE.2100432

Abstract:

We present a new -based Wallace-tree (CBW) 8×8 . The ‍’‍s s are implemented with a new hybrid (FA) cell, which is based on the (TG) technique. The proposed FA, TG-based AND gate, and hybrid half adder (HA) generate :3 (4≤≤7) digital s with the ability to save at least 50% area occupation. Simulations by 90 nm technology prove the superiority of the proposed FA and digital s under different conditions over the state-of-the-art designs. By using the proposed cells, the CBW exhibits high driving capability, low power consumption, and high speed. The CBW has a 0.0147 mm die area in a pad. The post-layout extraction proves the accuracy of experimental implementation. An mechanism is proposed, in which a direct interface between MATLAB and HSPICE is used to evaluate the presented CBW in image processing applications. The peak signal-to-noise ratio (PSNR) and structural similarity index metric (SSIM) are calculated as image quality parameters, and the results confirm that the presented CBW can be used as an alternative to designs in the literature.
