Innovation, practical benefits and prospects for the future development of automatic milking systems

Hongzhe JIANG,Wei WANG,Chunyang LI,Wei WANG

《农业科学与工程前沿（英文）》 2017年第4卷第1期页码 37-47 doi: 10.15302/J-FASE-2016117

摘要： Automatic milking systems (AMS) were designed to replace existing, labor-intensive machine milking and are an area of rapid development in modern dairy farming. The popularity of AMS lies in the convenience of management, decreasing workloads and the consistency of milking compared with non-automated machine milking. Nevertheless, this innovation has not been reviewed comprehensively and the practical benefits of AMS are still unclear. This review gives a brief overview of the historical development of milking machines and the workflow process of state-of-the-art AMS. In addition, a series of comparisons between AMS and current milking machines are made with respect to labor savings, quality parameters, udder health, herd behavior and mastitis detection and are summarized on the basis of relevant studies to show the benefits of the technological changes achieved by AMS. Finally, this review addresses several deficiencies in the technology and procedures of current AMS that need to be improved and also assesses recent advances in milking techniques with a particular focus on their potential for application in AMS.

Mapping the trends and prospects of battery cathode materials based on patent landscape

《能源前沿（英文）》页码 822-832 doi: 10.1007/s11708-023-0900-x

摘要： Advancing portable electronics and electric vehicles is heavily dependent on the cutting-edge lithium-ion (Li-ion) battery technology, which is closely linked to the properties of cathode materials. Identifying trends and prospects of cathode materials based on patent analysis is considered a kernel to optimize and refine battery related markets. In this paper, a patent analysis is performed on 6 popular cathode materials by comprehensively considering performance comparison, development trend, annual installed capacity, technology life cycle, and distribution among regions and patent assignees. In the technology life cycle, the cathode materials majorly used in electric vehicle have entered maturity stage, while the lithium cobalt oxide (LCO) cathode that is widely used in portable electronics is still in the growth stage. In global patent distributions, China holds more than 50% of total patents. In the top 10 patent assignees of 6 cathode materials, 2 institutes are from China with the rest being Japan (6) and Republic of Korea (2), indicating that the technology of cathode materials in China is relatively scattered while cathode research is highly concentrated in Japan and Republic of Korea. Moreover, the patent distribution has to consider practical issues as well as the impacts of core patents. For example, the high cost discourages the intention of applying international patents. This paper is expected to stimulate battery research, understand technical layout of various countries, and probably forecast innovative technology breakthroughs.

Progress, problems and prospects of porcine pluripotent stem cells

Hanning WANG,Yangli PEI,Ning LI,Jianyong HAN

《农业科学与工程前沿（英文）》 2014年第1卷第1期页码 6-15 doi: 10.15302/J-FASE-2014009

摘要： Pluripotent stem cells (PSCs), including embryonic stem cells (ESCs) and induced PSCs (iPSCs), can differentiate into cells of the three germ layers, suggesting that PSCs have great potential for basic developmental biology research and wide applications for clinical medicine. Genuine ESCs and iPSCs have been derived from mice and rats, but not from livestock such as the pig—an ideal animal model for studying human disease and regenerative medicine due to similarities with human physiologic processes. Efforts to derive porcine ESCs and iPSCs have not yielded high-quality PSCs that can produce chimeras with germline transmission. Thus, exploration of the unique porcine gene regulation network of preimplantation embryonic development may permit optimization of culture systems for raising porcine PSCs. Here we summarize the recent progress in porcine PSC generation as well as the problems encountered during this progress and we depict prospects for generating porcine naive PSCs.

The main achievements in the past 24 years and the prospects of mechanism research in China

ZOU Hui-jun, ZHANG Long, ZHANG Qing

《机械工程前沿（英文）》 2006年第1卷第3期页码 249-259 doi: 10.1007/s11465-006-0038-7

摘要： Since 1982, the symposiums on mechanism in China has been held fifteen times. In the past 24 years, Chinese mechanism has experienced a phenomenal development. Generally, fundamental research on traditional mechanisms is enhanced; mechanism and creative design of products are closely combined; modern mechanism with advanced and new technology is opened up; and mechanism is promoted to modernization. These are manifested in the following aspects: theory research on analysis and synthesis of traditional mechanism is deeply developed; computer-aided design on mechanisms is realized vigorously; conceptual design of mechanism system and mechanical products is energetically pushed; research on robot mechanisms and its industrial application is deeply developed; research on analysis and synthesis of controllable mechanisms and compliant mechanisms are energetically carried out; research on the dynamics of mechanisms and machines is vigorously developed; and reformation of teaching contents and system of mechanism is energetically carried out. Through the above-mentioned aspects of theory research and practical application, the theoretical and academic levels of Chinese mechanism can be considered at the advanced international level. However, there are not many original and breakthrough research achievements of fundamental research in China. In the meantime, there is a larger gap in the aspect of practical application of mechanism in the country compared with advanced countries in the world.

Real prospects for the development of power technologies based on renewable energy sources in Poland

Sławomir DYKAS, Artur SZYMAŃSKI, Xiaoshu CAI

《能源前沿（英文）》 2017年第11卷第2期页码 168-174 doi: 10.1007/s11708-017-0474-6

摘要： In Poland more than 40% of the power units have been operating for over 40 years now and more than 10% are over 50 years old, which indicates a high degree of decrease in the value of the energy sector. An analysis of the energy market shows that every year a new power plant should be built with a capacity of 1000 MW to ensure the national energy security. An energy market research indicates that in Poland the structure of energy production is changing in recent years—the share of fossil (solid) fuels in electricity and heat production was approximately 88% in 2009, while in 2004 it reached 93%. According to the analysis of the market, it can be seen that conventional energy, mainly based on coal and lignite, has been the most important segment of the sector for a long time.?In this paper the prospects for the development of power technologies based on renewable energy sources (RES) in Poland are presented.

Development and application prospects of piezoelectric precision driving technology

ZHAO Chunsheng, ZHANG Jiantao, ZHANG Jianhui, JIN Jiamei

《机械工程前沿（英文）》 2008年第3卷第2期页码 119-132 doi: 10.1007/s11465-008-0034-1

摘要： With the rapid development of science and technology, microelectronics manufacturing, photonics technology, space technology, ultra-precision machining, micro-robotics, biomedical engineering and other fields urgently need the support of modern precision driving theory and technology. Modern precision driving technology can be generally divided into two parts: electromagnetic and non-electromagnetic driving technology. Electromagnetic driving technology is based on traditional technology, has a low thrust-weight ratio, and needs deceleration devices with a cumbrous system or a complex structure. Moreover, it is difficult to improve positioning accuracy with this technology type. Thus, electromagnetic driving technology is still unable to meet the requirements for the above applications. Non-electromagnetic driving technology is a new choice. As a category of non-electromagnetic driving technology, piezoelectric driving technology becomes an important branch of modern precision driving technology. High holding torque and acute response make it suitable as an accurate positioning actuator. This paper presents the development of piezoelectric precision driving technology at home and abroad and gives an in-depth analysis. Future perspectives on the technology’s applications in the following fields are described: 1) integrated circuit manufacturing technology; 2) fiber optic component manufacturing technology; 3) micro parts manipulation and assembly technology; 4) biomedical engineering; 5) aerospace technology; and 6) ultra-precision processing technology.
