A novel method of plotting sensor sensitivity field and image reconstruction algorithm for electrical

CHEN De-yun, YANG Cong-jing, ZHENG Gui-bin, YU Xiao-yang, SUN Li-juan

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 2,   Pages 242-247 doi: 10.1007/s11465-006-0008-0

Abstract: Sensor sensitivity field in electrical capacitance tomography is affected by the distribution of multiphase medium, which is the peculiarity of soft field. This brings great difficulty for image reconstruction. To improve the quality of image reconstruction, it is important to analyze the distribution of the sensitivity field. In this article, using the finite element method, we expound a kind of novel plotting pattern to field, which is the distribution of sensitivity field through computer simulation. From experiments and results of sensitivity field analysis, a novel method of image reconstruction based on genetic algorithms is presented. The finite element model is correct and simulation result is fine by adopting unequal interval plotting patterns. At the same time, the result of image reconstruction has high precision.

Abstract: based on cryptography is a new paradigm in the field of nanotechnology. The overall performance of QCA is high compared to traditional complementary metal-oxide semiconductor (CMOS) technology. To achieve data security during nanocommunication, a cryptography-based application is proposed. The devised circuit encrypts the input data and passes it to an output channel through a cum data path selector, where the data is decrypted back to its original form. The results along with theoretical implication prove the accuracy of the circuit. Power dissipation and circuit complexity of the circuit have been analyzed.

Abstract:

A new microelectromagnetic relay is presented and fabricated based on micromachining technology, aiming at the miniaturization and high manufacturing efficiency of electromagnetic relays. This microrelay is composed of a lower magnetic circuit, a planar exciting coil, and an upper magnetic armature. A complete magnetic circuit is composed, and the ON and OFF states are controlled by the current of the exciting coil. The dimension of this microrelay is 5 mm ? 5 mm ? 0.4 mm. The fabrication process mainly includes lithography, sputtering, electroplating, etching, sacrifice-layer technology, etc. Electromagnetic force is calculated theoretically. The calculation results are used for the optimization design of the armature and the number of turns of the exciting coil.

Crop residues: applications of lignocellulosic biomass in the context of a biorefinery

Maria Carolina ANDRADE, Caio de Oliveira GORGULHO SILVA, Leonora Rios de SOUZA MOREIRA, Edivaldo Ximenes

Frontiers in Energy 2022, Volume 16, Issue 2,   Pages 224-245 doi: 10.1007/s11708-021-0730-7

Abstract: Interest in lignocellulosic biomass conversion technologies has increased recently because of their potential to reduce the dependency on non-renewable feedstocks. Residues from a variety of crops are the major source of lignocellulose, which is being produced in increasingly large quantities worldwide. The commercial exploitation of crop residues as feedstocks for biorefineries which could be used to produce a variety of goods such as biofuels, biochemicals, bioplastics, and enzymes is an attractive approach not only for adding value to residues but also for providing renewable products required by the expanding bioeconomy market. Moreover, the implementation of biorefineries in different regions has the potential to add value to the specific crop residues produced in the region. In this review, several aspects of crop residue application in biorefineries are discussed, including the role of crop residues in the bioeconomy and circular economy concepts, the main technical aspects of crop residue conversion in biorefineries, the main crop residues generated in different regions of the world and their availability, the potential value-added bioproducts that can be extracted or produced from each crop residue, and the major advantages and challenges associated with crop residue utilization in biorefineries. Despite their potential, most biomass refining technologies are not sufficiently advanced or financially viable. Several technical obstacles, especially with regard to crop residue collection, handling, and pre-treatment, prevent the implementation of biorefineries on a commercial scale. Further research is needed to resolve these scale-up-related challenges. Increased governmental incentives and bioeconomic strategies are expected to boost the biorefinery market and the cost competitiveness of biorefinery products.

Abstract: Carbon capture and storage (CCS) have acquired an increasing importance in the debate on global warming as a mean to decrease the environmental impact of energy conversion technologies, by capturing the CO produced from the use of fossil fuels in electricity generation and industrial processes. In this respect, post-combustion systems have received great attention as a possible near-term CO capture technology that can be retrofitted to existing power plants. This capture technology is, however, energy-intensive and results in large equipment sizes because of the large volumes of the flue gas to be treated. To cope with the demerits of other CCS technologies, the chemical looping combustion (CLC) process has been recently considered as a solution for CO separation. It is typically referred to as a technology without energy penalty. Indeed, in CLC the fuel and the combustion air are never mixed and the gases from the oxidation of the fuel (i.e., CO and H O) leave the system as a separate stream and can be separated by condensation of H O without any loss of energy. The key issue for the CLC process is to find a suitable oxygen carrier, which provides the fuel with the activated oxygen needed for combustion. The aim of this work is to explore the feasibility of using perovskites as oxygen carriers in CLC and to consider the possible advantages with respect to the scrubbing process with amines, a mature post-combustion technology for CO separation.

Exploration of Strategies for Chronic Disease Prevention and Control and Relevant System Development in China

Long-de Wang

Frontiers of Engineering Management 2015, Volume 2, Issue 1,   Pages 2-12 doi: 10.15302/J-FEM-2015002

Abstract: Chronic non-communicable diseases have become a major threat to humanity. International studies have shown that of 57 million deaths worldwide in 2008, 36 million (63%) were caused by chronic non-communicable diseases; of these, 29 million (80%) occurred in low and middle income countries. The WHO predicts that if the current trend continues, the annual number of deaths due to chronic non-communicable diseases will increase to 55 million by 2030. Due to acceleration of industrialization and urbanization, along with population aging and rapid changes of people’s lifestyle, the morbidity and mortality from chronic diseases are rapidly increasing in China. Therefore, dealing with the prevalence of chronic non-communicable diseases has become one of the current major health issues for China to address. On the basis of summarizing the status of major chronic diseases in China, analyzing the key issues and key factors in chronic disease prevention and control, and reviewing and summarizing the experience from the previous projects, this paper proposes the following recommendations as strategies for chronic disease prevention and control and development of relevant system, which China should adopt. All relevant government departments should formulate corresponding policies; establish a coordinated and efficient work system with rational structure and clear division of tasks and responsibilities within the system. Implementation and development of “integrated medicine” in system is necessary. Work norms and requirements will then improve the performance and efficiency in chronic disease prevention and control in China.
