Homology Priority Task Scheduling in μC/OS-Ⅱ Real-Time Kernel

μC/OS-Ⅱ is an open source real-time kernel adopting priority preemptive schedule strategy. Aiming at the problem of μC/OS-Ⅱ failing to support homology priority tasks scheduling, an approach for solution is proposed. The basic idea is adding round-robin scheduling strategy in its original scheduler in order to schedule homology priority tasks through time slice roundrobin. Implementation approach is given in detail. Firstly, the Task Control Block （TCB） is extended. And then, a new priority index table is created, in which each index pointer points to a set of homology priority tasks. Eventually, on the basis of reconstructing μC/OS-Ⅱ real-time kernel, task scheduling module is rewritten. Otherwise, schedulability of homology task supported by modified kernel had been analyzed, and deadline formula of created homology tasks is given. By theoretical analysis and experiment verification, the modified kernel can support homology priority tasks scheduling, meanwhile, it also remains preemptive property of original μC/OS-Ⅱ.     

A NEW DESCRIPA NEW DESCRIPTOR OF AMINO ACIDS BASED ON THE THREEDIMENSIONAL VECTOR OF ATOMIC INTERACTION FIELD

QUANTITATIVE STRUCTURE ACTIVITY RELATIONSHIP (QSAR) IS A VERY IMPORTANT TOPIC FOR MANY SCIENTIFIC FIELDS AND CAN BE TERMED AS QUANTITATIVE SEQUENCE ACTIVITY MODELS(QSAM)[1] WHEN REFERRED TO THE RESEARCH ON RELATION- SHIPS BETWEEN STRUCTURES AND ACTIVITIES OF BIOLOGICAL MOLECULES, SUCH AS PROTEINS, AND NUCLEIC ACIDS. HOW- EVER, IT IS VERY DIFFICULT TO ESTABLISH A QSAM MODEL,…     

基于动态拓扑有领航者的智能群体群集运动控制

对具有二次积分动态的智能群体跟随领航者实现群集运动编队,提出了一个分散控制方法对智能群体进行分散控制。基于动态时变有领航者的网络拓扑,用图论模型表示智能体之间的相互作用及通信关系,运用推广的Lyapunov理论、微分包含及非平滑分析进行了稳定性分析,并得到所有智能体速度方向收敛到同一方向并与领航者保持一致;所有智能体速度大小收敛并与领航者相同;互连的智能体之间没有碰撞发生;所有智能体的人工势场函数被最小化等重要结论。给出了一个仿真实例,验证了该方法的有效性。

壮语里t-(t‘-)>s-的音变现象是存在的,不论是汉语,或者是壮语,它们的内部或两者之间都存在着s-与t-(t‘-)对应的规律。     

软件补偿方法在测温智能仪表中的应用

软件补偿方法具有效果好、精确度高、成本低的优点。介绍了在研制多点巡回检测仪中采用的几种软件补偿方法：前向通道特性补偿使放大器等元件不因外界条件的变化而受到任何影响；引线电阻的补偿可实现引线电阻对系统无任何影响；热电阻、热电偶的非线性度补偿效果明显，节省开销。     

一类泛圈图

本文证明了如果G是2连通无爪图,G不是圈,n=|v(G)|>q,G的每个导出子图A都满足φ(a_1,a_2),且G中不存在W′作为其导出子图,则G是泛圈图。
