Facing Challenges and Searching Chances at the Same Time——The Present Status of Chinese Flower Enterprise

Chen Junyu

Strategic Study of CAE 2002, Volume 4, Issue 10,   Pages 17-20

Abstract:

This report points out that the flower enterprise is a promising enterprise, growing up continuously and becoming better and better. The author then compares and analyses differences and commonalities between the Chinese flower enterprise and the world flower enterprise. Using ’99 Kunming International Horticultural Exposition as an example, the author is convinced that Chinese gardens and flowers may reach the first level in the world, but “Chinese Characteristics” ought to be strengthened significantly. At the beginning of China’s becoming a member of WTO, a very good way has been found for facing challenges and utilizing good chances——the so-called “Hua-Hui Xin Si Hua”，viz,①traditional Chinese famous flowers internationalized;②world famous flowers becoming“sinicized” and localized;③ wild flowers introduced and acclimatized;④flower production and management highly specialized and in large-scale. It is possible to reach the present level of flower development in the world in 50 years or more. Then，China will be turned from the “Mother of Gardens” to the “Kingdom of World Flowers”.

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.

Robust ensemble of metamodels based on the hybrid error measure

Frontiers of Mechanical Engineering 2021, Volume 16, Issue 3,   Pages 623-634 doi: 10.1007/s11465-021-0641-7

Abstract: Metamodels have been widely used as an alternative for expensive physical experiments or complex, time-consuming computational simulations to provide a fast but accurate analysis. However, challenge remains in the prior determination of the most suitable metamodel for a particular case because of the lack of information about the actual behavior of a system. In addition, existing studies on metamodels have largely restricted on solving deterministic problems (e.g., data from finite element models), whereas some real-life engineering problems (e.g., data from physical experiment) are stochastic problems with noisy data. In this work, a robust ensemble of metamodels (EMs) is proposed by combining three regression stand-alone metamodels in a weighted sum form. The weight factor is adaptively determined according to the hybrid error metric, which combines global and local error measures to improve the accuracy of the EMs. Furthermore, three typical individual metamodels that can filter noise are selected to construct the EMs to extend their application in practical engineering problems. Three well-known benchmark problems with different levels of noise and three engineering problems are used to verify the effectiveness of the proposed EMs. Results show that the proposed EMs have higher accuracy and robustness than the individual metamodels and other typical EMs in major cases.

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.

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 3,   Pages 457-469 doi: 10.1631/FITEE.2200361

Abstract:

cellular automata (QCA)%29&ck%5B%5D=abstract&ck%5B%5D=keyword'> is a new nanotechnology for the implementation of nano-sized digital circuits. This nanotechnology is remarkable in terms of speed, area, and power consumption compared to complementary metal-oxide-semiconductor (CMOS) technology and can significantly improve the design of various logic circuits. We propose a new method for implementing a in QCA technology in this paper. The proposed method uses the intrinsic features of QCA in timing and clock phases, and therefore, the proposed cell structure is less occupied and less power-consuming than existing implementation methods. In the proposed , compared to previous best designs, reductions of 6.45% in area occupation and 44.49% in power consumption were achieved. In addition, for the first time, a reset-based and a with set and reset capabilities are designed. Using the proposed , a new 3-bit is developed which reduces 2.14% cell numbers compared to the best of previous designs. Moreover, based on the 3-bit , a 4-bit is designed, which reduces 0.51% cell numbers and 4.16% cross-section area compared to previous designs. In addition, two selective s are introduced to count from 0 to 5 and from 2 to 5. Simulations were performed using and tools in coherence vector engine mode. The proposed circuits are compared with related designs in terms of delay, cell numbers, area, and leakage power.
