利用Matlab和Simulink对DSP进行系统级的设计方法

本文介绍了利用Matlab和Simulink中Developer‘s Kit for TI DSP工具对DSP进行系统级设计的方法。     

双参数Bézier曲线的升二次扩展

本文以二次Bernstein基函数为例,首次提出了含双参数基函数的新扩展——αβQ—Bern-stein基函数,此类基函数具有新的特点,即基函数的扩展次数一次性升高两次,且包含了二次多项式和带一个参数的三次多项式基函数的所有性质。基于这组基函数定义了αβQ—Bézier曲线,该曲线也含有参数,具有形状可调性,当α与β取某些值时曲线能达到C4连续或在某个端点处C0连续。最后与含两个参数的升一次Bézier曲线进行比较,该曲线具有调节范围广、灵活性更强的优势。     

Configurational statistics of copolymers prepared by complex-radical polymerization

Radical copolymerization is considered theoretically taking into account the effect of complexing on the configurational statistics of macromolecules formed. Akinetic model has been developed that considers, apart from the ordinary addition of single monomer units to a propagating chain, the possible addition of monomer unit pairs along with a complexing agent in the form of a ternary complex. Within the framework of this model, the problem of calculating the probabilities of formation of any sequences of monomer units (taking into account their microtacticity) in a macromolecule has been rigorously solved as well as the problem of finding the composition distribution of the copolymer formed. It has been shown that this distribution is described by a conventional Gauss law and the appropriate parameters are given. Possible generalizations of the suggested approach are indicated.     

IDE驱动程序分析及SATA驱动程序移植

SATA硬盘已经是目前多媒体应用中被广泛使用的存储介质, 而有些多媒体产品的Linux版本中, 并不支持SATA驱动框架。本文通过对Linux下IDE驱动框架及其相关的Linux驱动代码的分析, 提供了一种在IDE驱动程序框架下移植SATA驱动程序的方法。最后以SiI3512为例, 介绍了SATA驱动程序的移植过程。对于其它此类系统的移植具有很好的借鉴作用。     

纤维素酶的固体发酵

从来自国内外11株菌株的初步比较,筛选出酶活较高的康氏木霉N_2—78和瑞热埃木霉QM6a。对康氏木霉P_2和土曲霉3.3935所作的纤维素碳源试验中,发现木质纤维素较纯纤维素好,未经处理的木质纤维素比经处理的好。麸皮和稀土对康氏木霉P_2产酶作用影响较大,而对土曲霉3.3935则无明显的影响。     

1—AGO灰关联分析模型

对灰关联分析中关联系数以及关联度加以改进,给出了1—AGO关联系数以及1—AGO关联度,讨论了它们的有关性质,并建立了1—AGO灰关联分析模型,使之更具有合理性和科学性.     

高职院校会计专业工学结合人才培养路径新探索

我国高职院校会计专业正处于人才培养路径的新探索时期,实施"工学结合"的培养路径是一种必然趋势。然而目前,高职会计教育的工学结合改革中存在诸多问题,文章深入分析了制约我国高职院校会计专业工学结合的因素,包括会计行业的自身局限性、实施会计专业工学结合的社会经济条件不足等,最后从高职会计教育最薄弱同时又是很重要的两个环节提出了改革建议。     

Control 5.0: From Newton to Merton in Popper's Cyber-Social-Physical Spaces

The future of control in cyberspace of parallel worlds is discussed. It argues for the coming age of Control 5.0, the control technology for the new IT capable of dealing with artificial worlds with VR, AR, AI and robotics. The discipline of automation needs a new interpretation of its core knowledge and skill set of modeling, analysis, and control for cyber-socialphysical systems, and a paradigm shift from Newtonian Systems with Newton's Laws or Big Laws with Small Data to Mertonian Systems with Merton's Laws or Small Laws with Big Data.      

三峡—葛洲坝梯级水利枢纽调度关键数据分析

针对三峡—葛洲坝梯级水利枢纽运行的流量、水位、电力数据进行相关分析研究,揭示出三峡出库流量与葛洲坝入库流量、葛洲坝毛水头与耗水率、葛洲坝出库流量与葛洲坝下游水位相互关系和变化规律,并根据拟合的关系线制成关系表,以指导葛洲坝工程出力预报及修订水库调度出力计划。     

浅谈高职计算机专业的创新教育

如何在计算机教育中培育具有创新能力和创新意识的新型人才是高职计算机专业亟待解决的问题,只传授知识、技能的传统的教学方法已不能满足培养创新型人才的需求。从计算机教学中存在的问题出发,提出支撑创新型人才培养的相关改革措施。
