摘要：In recent studies, reversible logic has emerged as a great scene of research, having applications in low power CMOS circuits, optical computing, quantum computing and nanotechnology. The classical logic gates such as AND, OR, EXOR and EXNOR are not reversible. In the existing literature, reversible sequential circuits designs are offered that are improved for the number of the garbage outputs and reversible gates. Minimizing the number of garbage is very noticeable. In the present paper, we show a design of the reversible comparator based on the quantum gates implementation of the reversible DG gate. The reversible DG gate is designed by using 3 × 3 quantum gates such as NOT, CNOT, Controlled-V and Controlled-V+ gates. Also, we have used the TR gate and various types of quantum gates in the implementation results. Low power three-bit comparator is designed using DG Gate, New Gate and Fredkin Gate. In order to evaluate the benefit of using the DG gate proposed in this paper, one-bit comparator is constructed. The design is useful for the future computing techniques like quantum computers. The proposed designs are implemented using VHDL and functionally investigated using Quartus II simulator.

摘要：Brain-like computer research and development have been growing rapidly in recent years. It is necessary to design large scale dynamical neural networks (more than 106 neurons) to simulate complex process of our brain. But such kind of task is not easy to achieve only based on the analysis of partial differential equations, especially for those complex neural models, e.g. Rose-Hindmarsh (RH) model. So in this paper, we develop a novel approach by combining fuzzy logical designing with Proximal Support Vector Machine Classifiers (PSVM) learning in the designing of large scale neural networks. Particularly, our approach can effectively simplify the designing process, which is crucial for both cognition science and neural science. At last, we conduct our approach on an artificial neural system with more than 108 neurons for haze-free task, and the experimental results show that texture features extracted by fuzzy logic can effectively increase the texture information entropy and improve the effect of haze-removing in some degree.

摘要：一次成型冷弯型钢机组常采用异步电机的开环控制模式调整轧辊位置来实现轧制参数的调整,该系统存在效率低、参数整定难以及维护成本高等问题。采用拉绳式测距传感器构成轧辊位置闭环控制虽可行,但实际工况存在水、油和高频噪声等恶劣因素影响,致使拉绳式测距传感器极易发生故障,由此可能导致“挤辊”等恶性安全事故。为此,综合考虑现场环境,经硬件设计实验筛选,设计了一种改进的轧辊位置自动调整控制系统。该系统采用磁栅尺作为测距传感器,并与安装在同一测量点电机传动轴上的增量式旋转编码器构成位置信息冗余,引入标准不确定度作为性能评估指标,完成测距传感器的性能评估与故障诊断,采用西门子S7-200 SMART型可编程逻辑控制器(PLC)作为从站控制器,通过采集模块采集磁栅尺及编码器的位置数据,采用接近开关作为零点标定。经现场调试运行结果表明,改进后的系统稳定性好,易操作,轧辊位置调整精度可达±1 mm,用时少,满足了轧辊位置自动调整的要求,提高了企业生产效率。

摘要：三、与音乐艺术意志相关的音乐每一件艺术作品,都必须表现某种东西。这也就是说,任何一件作品的内容。音乐不但是声音的聚合物,更是意义的载体,意义是人所赋予音乐的,或者说是存在于人的理解活动之中的。离开了人的意识,离开人的感受,我们对音乐的理解以及音乐的意义便无从谈起。正是因为这个道理,"审美对象只有被知觉才是存在"。音乐的意义与内涵,只有在欣赏和感悟中理解,才能够得到最终的完成。
