最近30年来,离散滑模控制(DSMC)被加以研究.在现有离散滑模控制的文献中,不但有完善的理论,并且有应用的实例.计算机通信网络(涵盖有线和无线情形)的发展给控制专家提出了具有挑战性的问题.此类系统的响应很快,因此要求控制器必须能快速反应.同时,此类系统中的数据包和路由采用固有的切换方式.因此,在该网络系统中采用与其固有切换类似的滑动模态控制成为一个有趣的问题.本文应用离散滑模控制方法来解决通信网络的拥塞控制问题.在过去几年中,许多反馈控制方法被用来解决通信网络的许多问题,如流量控制,拥塞控制和功率控制.本文提出了一种新的应用滑动模态控制来实现通信网络拥塞控制的方法.由于计算机通信网络处理的是数字数据且在本质上是离散的,因此其是一类离散时间系统,因而可应用离散滑模控制.在该系统中,比特率保持恒定不变,通过调整缓冲区的长度来控制拥塞.出于模拟与分析的目的,缓冲区的最大长度被设为250bit.本文展示了离散滑模控制能够实现通讯网络不同特性的控制.

Recent advances in production,purification and applications of phycobiliproteins

World Journal of Biological Chemistry 2016年第1期7卷 100-109页

作者： Ravi Raghav Sonani Rajesh Prasad Rastogi rutvij Patel Datta Madamwar BRD School of Biosciences Sardar Patel University

An obligatory sunlight requirement for photosynthesis has exposed cyanobacteria to different quantity and quality of light. Cyanobacteria can exhibit efficient photosynthesis over broad region(450 to 650 nm) of solar spectrum with the help of brilliantly coloured pigment proteins called phycobiliproteins(PBPs). Besides light-harvesting, PBPs are found to involve in several life sustaining phenomena including photoprotection in cyanobacteria. The unique spectral features(like strong absorbance and fluorescence), proteineous nature and, some imperative properties like hepato-protective, antioxidants, anti-inflammatory and anti-aging activity of PBPs enable their use in food, cosmetics, pharmaceutical and biomedical industries. PBPs have been also noted to show beneficial effect in therapeutics of some disease like Alzheimer and cancer. Such large range of applications increases the demand of PBPs in commodity market. Therefore, the large-scale and coast effective production of PBPs is the real need of time. To fulfil this need, many researchers have been working to find the potential producer of PBPs for the production and purification of PBPs. Results of these efforts have caused the inventions of some novel techniques like mixotrophic and heterotrophic strategies for production and aqueous two phase separation for purification purpose. Overall, the present review summarises the recent findings and identifies gaps in the field of production, purification and applications of this biological and economically important proteins.

Is osteoporosis systemic?

引用

Advances in Bioscience and Biotechnology 2013年第4期4卷 531-538页

作者： Ronald L. Huston Kenneth L. Weiss rutvij Kotecha Mina Dimov Material Science and Engineering University of Cincinnati Cincinnati USA Neuroimaging Research and Radiology University of Mississippi Medical Center Jackson USA School of Dynamic Systems University of Cincinnati Cincinnati USA

The title question is investigated by comparing results of a series of bone strength tests of lumbar vertebrae (L1 and L2) and right wrists (distal radii) of nine cadavers. The paper describes the specimen preparation, the testing, and the analysis procedures. The results show that there is a correlation between the strengths of the lumbar and wrist specimens for the individual cadavers, suggesting that bone integrity is indeed systemic.
