制图综合是传统的地图生产不可缺少的技术手段之一，是地图学的核心理论和制图学者关注的焦点问题。它的实质是解决地图内容随比例尺的变化而产生的多尺度表达的问题。其任务是对地图内容随比例尺变化过程中的增减进行合乎制图学理论要求的综合变换。 本PPT对于地图制作人员和学生了解制图综合具有很大的帮助。

谷物作为主要粮食和饲料作物,在农业生产中占有重要地位。提高谷物产量和质量的主要方法是选育出优质品种,而在选育品种过程中,对种子的计数是不可缺少的内容。目前,种子的计数方法通常采用人工计数,或半自动的光电计数器,很显然传统的计数方法存在着效率低、准确性不高等缺点。笔者利用计算机图像识别和处理技术实现考种过程中的计数,为谷物粒群的识别、精选、分级等的进一步研究奠定必要的理论与实践基础,并为育种工作提供一种高效、快捷的谷物计数新技术 用Matlab实现这种方法，既能分步对谷物颗粒图像预处理算法进行仿真测试，又可以很直接地得到谷物颗粒个数的结果。实验证明，用Matlab实现的处理结果比较理想，满足识别的应用性。本文介绍用matlab实现了对谷物颗粒图像的灰度化处理、去除噪声处理、灰度图像的二值化、谷物颗粒的数值计算等。并选取较好的处理步骤和算法参数解决谷物颗粒图像预处理的问题。(The grain plays an important role in the production of agriculture as main food supplyment of mankind and animals. The main way to improve grain yield and quality is to breed high-quality varieties.However, in the process of breeding varieties, counting seeds is an essential element.Nowadays, the counting of seeds is usually done manually,or semi-automatic photoelectric counter. It is obvious that the traditional counting method has the disadvantages of low efficiency and low accuracy. The use of computer image recognition and processing technology to achieve the counting test in the process of selection for identification, grain group, lay the theoretical and practical foundation for further research of the necessary classification, and for breeding work provides an efficient, fast new grain counting technique)

说明：  本文介绍了一种新型变刚度执行机构(CompAct-VSA)的设计与建模。压实- vsa的工作原理是基于具有连续调节枢轴点的杠杆臂机构。提出的概念允许开发具有大刚度范围和快速刚度调节响应的驱动单元。执行机构的实现利用凸轮形杠杆臂与可变枢轴驱动齿条和小齿轮传动系统。这种实现导致了高度集成和模块化的组装。尺寸和重量确实是VSAs设计中的一个开放问题，这最终限制了它们在多自由度机器人系统中的实现。本文介绍了执行机构的原理、工作原理和模型。初步结果表明，所提出的压实vsa设计具有快速的刚度调节响应和较大的刚度范围。(This paper describes the design and modelling of a new variable stiffness actuator (CompAct-VSA). The principle of operation of CompAct-VSA is based on a lever arm mechanism with a continuously regulated pivot point. The proposed concept allows for the development of an actuation unit with a wide range of stiffness and a fast stiffness regulation response. The implementation of the actuator makes use of a cam shaped lever arm with a variable pivot axis actuated by a rack and pinion transmission system. This realization results in a highly integrated and modular assembly. Size and weight are indeed an open issue in the VSAs design, which ultimately limit their implementation in multi-dof robotic systems. The paper introduces the mechanics, the principle of operation and the model of the actuator. Preliminary results are presented to demonstrate the fast stiffness regulation response and the wide range of stiffness achieved by the proposed CompActVSA design.)
