无刷电机是在嵌入式系统中广泛使用的动作机,文章给出了一种巧妙的无刷电机驱动方法,并且提供了驱动电机所需的汇编代码,用便捷廉价的方法,实现了无刷电机的驱动,而且有一个关键优势:不需要传感器!-brushless motor is in embedded system widely used in aircraft movements. The article gives a deceptively brushless motor drive, and provides the necessary drive motor assembly code, with convenient and cheap method to achieve a brushless motor drive, but is a key advantage : no need for sensors!

心率指心脏每分钟搏动的次数, 它能够反映心脏的工作状态。正常心率决定于窦房结的节律性, 成人静息时约60～100 次/ min , 平均约75次/ min。心率可因年龄、性别及其他因素而变化。初生儿心率约130 次/ min , 随年龄增长而逐渐减慢, 至青春期乃接近成人的心率。女性心率比男性稍快 运动员心率较慢。成人安静心率超过120 次/ min 者, 为心动过速 低于40 次/ min 者为心动过缓。心率受植物性神经和体液因素调节。-Heart rate means the number of pulse per minute, it can reflect the work of the state of the heart. Normal heart rate determined by the rhythm of the sinoatrial node, resting adult is about 60 ~ 100 times/min, an average of about 75 times/min. Heart rate may be due to age, gender and other factors change. Heart rate of newborn infants of about 130/min, growth has gradually slowed down with age, to adolescence adult heart rate is near. Women slightly faster rate than men athletes slow heart rate. Quiet adult heart rate over 120 times/min, and for the tachycardia less than 40 times/min for bradycardia. Heart rate by the plant regulate neural and humoral factors.

设有n项独立的作业{1,2,…, n},由m台相同的机器加工处理。作业i所需要的处理时间为ti。约定：任何一项作业可在任何一台机器上处理，但未完工前不准中断处理；任何作业不能拆分更小的子作业。多机调度问题要求给出一种调度方案，使所给的n个作业在尽可能短的时间内由m台机器处理完。设计算法。 -Stand-alone operation with n items (1,2, ..., n), by m units the same machine processing. Job i the processing time required to ti. Convention: any one job can be processed on any machine, but does not pre-completion are not allowed to interrupt processing any operation can not be split smaller sub-operations. Multi-machine scheduling problem requires paper, a scheduling program, so that given the n-operation in the shortest possible time processed by m machines. Design algorithms.

设计一个可以顺计时和倒计时的秒表。要求计时的范围为00.0S~99.9S，用三位数码管显示。用VHDL语言-Designed to be a cis-timing and countdown stopwatch. Required time ranges from 00.0S ~ 99.9S, with three digital tube display.

擅 蔓：以人脸的表情识别为实验背景， 分析了在对人脸表情的识别过程中，单个独立分薰对识别率的影响，由此进一步总结了在表情识 别中如何更有效地选取独立子空间，以实现在不影响识别率的前提下，减少用于构成独立子空问所需的独立分量的个数。 独立成分分析；表情识别；独立子空间 -Good man: Face to face identification for the experimental background, the analysis of facial expressions in the identification process, a single smoked separate the impact of the recognition rate, thus further summarized in the expression recognition of how to more effectively select the independent sub-space in order to achieve the recognition rate does not affect the premise, for constituting a separate sub-reducing space required for the number of independent component. Independent component analysis expression recognition independent subspace

给出了沉浸式虚拟维修仿真系统的框架，从样机建模和交互技术两个方面对其关键技术进行了研究．提出 了虚拟维修样机的概念，通过定义样机部件的约束运动和交互特征来实现其所要求功能，而交互技术则主要集中在 抓取和防穿越处理上．建立了基于Jack系统的沉浸式虚拟维修仿真原型系统，并以某机构的拆装为例对其进行了初 步的应用验证-Give the Immersive Virtual Maintenance Simulation System framework, from prototype modeling and interactive technology for its two key technology areas were studied. Put forward the concept of a virtual prototype of repair, by the definition of prototype components bound to exercise and interactive features of implementation of its functional requirements, and the interactive technology was mainly concentrated in the crawl up and deal with anti-crossing. Jack set up a system based on Immersive Virtual Maintenance Simulation prototype system and the dismantling of an institution as an example of its application for a preliminary verification
