Description: PVector
The most basic building block for programming motion is the vector. And so this is where we begin. Now, the word vector can mean a lot of different things:
Vector is the name of a new wave rock band formed in Sacremento, CA in the early 1980s. It s the name of a breakfast cereal manufactured by Kellogg s Canada. In the field of epidemiology, a vector is used to describe an organism that transmits infection from one host to another. In the C++ programming language, a Vector (std::vector) is an implementation of a dynamically resizable array data structure. Platform: |

Description: 现在市面上流行的小型雕刻机工作台主要有两种。第一种如图1所示工作台只作Y方向的移动，而刀具作X方向和Z方向的移动。第二种则如图2所示工作台作X,Y方向的移动，而刀具只作Z方向的移动。
结构1的优点是制作容易，结构稳定。但由于工件随工作台移动，所以不能加工太重的工件，而且雕刻机尺寸不能太大。结构2虽然制作也较容易，然而稳定性要比结构1差很多。由于本次设计对机械部件结构的要求就是要小而轻便，加工工件的质量也是比较轻，因此选用结构1。
在该结构中，机械本体部分是雕刻机的骨架，有底座、立柱、工作台、机头和主轴组件等部分。在保证整个系统的机械刚性的前提下，为了简化设计的结构，减轻整机重量，缩短产品的设计和制造的周期，其主体框架采用铝合金制造，防护件用塑料件制造，用标准的紧固件和定位销连接。-Now the market popular small engraving machine mainly has two kinds. First, as shown in Figure 1work station only Y directional movement, and the tool for X direction and the Z direction of mobile. The second is as shown in Figure 2work station for X, Y directional movement, and the cutting tool is only Z directional movement.Structure 1has the advantages of easy fabrication, structure stability. But as a result of the workpiece with the motion of the working table, so not too heavy workpiece processing, and engraving machine size too large. Structure 2although the production is easy, but the stability of structure 1is much worse than. Due to the design of mechanical parts requirement is to be small and lightweight, machining quality is also quite light, therefore the selection of structure 1.In this structure, the mechanical part is the engraving machine frame, a base, a column, table, machine head and the spindle components such as part of.

Description: 绘制庞加莱截面图的程序。先通过solveLor.m来求出一系列点，然后代入Poincare_section 程序绘制庞加莱截面。
通过观察Poincare截面上截点的情况可以判断
是否发生混沌：当Poincare截面上有且只有一个不动点或少数离散点时，运动是周期的；当Poincare截面上是一封闭曲线时，运动是准周期的 当Poincare截面上是一些成片的具有分形结构的密集点时，运动便是混沌。 -Poincare section drawing program. First obtained by solveLor.m to a series of points, and then drawn into the program Poincare Poincare section. By observing the situation on the Poincare section cut points can determine whether chaos occurs: When there is only one fixed point or a few discrete points on the Poincare section, the motion is periodic When is a closed curve on the Poincare section, the motion is quasi- When is the point of having a dense fractal structure on some stretches of the Poincare section, the motion is chaotic period.

Description: This paper aims to present a new method for generating incoherent seismic ground
motions on the basis of the stochastic deconvolution technique and the spectral representation
method. The generated free field motion satisfies the imposed statistical properties on the free
surface and is composed of elementary plane waves of types SH, P-SV incoming from all directions. This will allow 3D soil-structure interaction analyses to be performed with spatially
varying seismic motions in the case of structure with embedded foundation. Eventually, structural non-linearity can be accounted for when the SSI analysis is performed in the time domain. Platform: |

Description: Flexible structures in motion have specific features that are not a secret to a
structural engineer. One of them is resonance—strong amplification of the motion at
a specific frequency, called natural frequency. There are several frequencies that
structures resonate at. A structure movement at these frequencies is harmonic, or
sinusoidal, and remains at the same pattern of deformation. This pattern is called a
mode shape, or mode. The modes are not coupled, and being independent they can
be excited separately. More interesting, the total structural response is a sum of
responses of individual modes. Another feature—structural poles—are complex
conjugate. Their real parts (representing modal damping) are typically small, and
their distance the origin is the natural frequency of a structure.-Flexible structures in motion have specific features that are not a secret to a

Description: 这是一个基于openGl制作的一个手势识别程序(This is a 3D hand model developed mainly for vision-based hand motion analysis. The hand model is modeled as a set of rigid quadratic surfaces, and has 27 degrees-of-freedom (DoFs) including 6 DoFs of global motion and 21 DoFs of local motion. The hand skeleton is modeled as a kinematic chain of 20 joints connected by bones in a tree structure with the root at the wrist. In this program you can view the model from different positions and perspectives, and manipulate each DoF separately. More importantly, to assist research in this area, we also provide functions to generate the depth image, silhouette image and edge images, which can be easily used for model-based matching between the input and the 3D hand model.)

Description: 滑模变结构控制本质上是一类特殊的非线性控制，其非线性表现为控制的不连续性，这种控制策略与其它控制的不同之处在于系统的“结构”并不固定，而是可以在动态过程中根据系统当前的状态(如偏差及其各阶导数等)有目的地不断变化，迫使系统按照预定“滑动模态”的状态轨迹运动。由于滑动模态可以进行设计且与对象参数及扰动无关，这就使得变结构控制具有快速响应、对参数变化及扰动不灵敏、无需系统在线辩识， 物理实现简单等优点。(In essence, sliding mode variable structure control is a special kind of nonlinear control, whose nonlinear performance is the discontinuity of control. The difference between this control strategy and other controls is that the "structure" of the system is not fixed, but it can change purposefully in the dynamic process according to the current state of the system (such as deviation and its derivatives of each order, etc.), forcing the system to "slide" according to the preset State track motion of "dynamic mode".)
