The Princess Didries

It was a bright, sunny September morning, and I was in a huge, pale pink ball gown, with a tiara on my head, waving to the crowds on either sides of the street. I was sitting on a float with eight other girls, who were all wearing the same ball gown, grinning from ear to ear as the parade continued down the boardwalk from one end of the beach to the other. While some people may feel awkward or uncomfortable to be on display in a parade like that, I thought it was an exhilarating （令人振奋的） experience.     

Dynamic response of a beam on a Pasternak foundation and under a moving load

The dynamic response of an infinite beam placed on a Pasternak foundation when the system was subjected to a moving load was investigated. We used the double Fourier transform and its inversion to solve the formulations of the problem. A closed form analytic solution of the beam was obtained by the theorem of residues. We selected a numerical example to illustrate the dynamic response of the beam on Pasternak and Winkler foundations, respectively. We discuss the effect of the moving load velocity on the dynamic displacement response of the beam. The maximum deflection of the beam increases slightly with increased load velocity but increases significantly with reduced shear modulus of subgrade at a given velocity. The maximum deflection of a beam resting on a Pasternak foundation is much smaller than that of a beam on a Winkler foundation.

The story happened in France began with a little nice metal can lying quietly on a concrete pillar.A boy's voice was talking about the games he liked most to play.His name is Julian.The can was a present sent by his mum,who was seriously ill and loved him very much. One day,a girl called Sophie came into his sight.She came from Poland,and not accepted by French people.The boy gave the can to her and the story between them started from then on.They made bets on a lot of crazy things,making fun of the teacher, pulling the big cake to the floor on a wedding ceremony... With the can and these bets,they grew up,but the only thing unchanged was their still communicating with each other making     

Novel approach for determining the optimal axial preload of a simulating rotary table spindle system

This paper presents a new theoretical model to determine the optimal axial preload of a spindle system, for challenging the traditional method which relies heavily on experience of engineers. The axial preloading stiffness was treated as the sum of the spindle modal stiffness and the framework elastic stiffness, based on a novel concept that magnitude of preloads can be controlled by measuring the resonant frequency of a spindle system. By employing an example of a certain type of aircraft simulating rotary table, the modal stiffness was measured on the Agilent 35670A Dynamic Signal Analyzer by experimental modal analysis. The equivalent elastic stiffness was simulated by both finite element analysis in ANSYS? and a curve fitting in MATLAB?. Results showed that the static preloading stiffness of the spindle was 7.2125×107 N/m, and that the optimal preloading force was 120.0848 N. Practical application proved the feasibility of our method.

Application of automated image analysis to the identification and extraction of recyclable plastic bottles

An experimental machine vision apparatus was used to identify and extract recyclable plastic bottles out of a conveyor belt. Color images were taken with a commercially available Webcam, and the recognition was performed by our homemade software, based on the shape and dimensions of object images. The software was able to manage multiple bottles in a single image and was additionally extended to cases involving touching bottles. The identification was fulfilled by comparing the set of measured features with an existing database and meanwhile integrating various recognition techniques such as minimum distance in the feature space, self-organized maps, and neural networks. The recognition system was tested on a set of 50 different bottles and provided so far an accuracy of about 97% on bottle identification. The extraction of the bottles was performed by means of a pneumatic arm, which was activated according to the plastic type; polyethylene-terephthalate （PET） bottles were left on the conveyor belt, while non-PET bottles were extracted. The software was designed to provide the best compromise between reliability and speed for real-time applications in view of the commercialization of the system at existing recycling plants.

Impact of inert metal particles flow on aluminium plate

Inert metal explosive,a new kind of explosive,is a mixture of high explosive and inert metal particle.When this kind of explosive is detonated,an inert metal particle flow will be formed by the ex-plosive product driving.To determine the characteristics of the movement of the metal particle flow,a series of aluminium plates were designed to be the targets on which the metal particle flow impacted.The test result was presented and a numerical model was set up to analyze the impact of the high speed inert metal particles on aluminium plate.Based on the numerical analysis,the relationship between the characteristic of the mark on the target plate and the initial condition of the inert metal particles was pro-posed.From the analysis of the impact on target plates,more information about the movement of the metal particles could be reconstructed.

His first words after stepping on the moon were, "That's one small step for a man, one giant leap for mankind."1 This event was televised to Earth and seen by millions! Armstrong was born in Wapakoneta, Ohio in 1930. He was on a plane for the first time at the age of six. He took flying lessons in his teens and got…     

Captain Cook

James Cook was born on October 27, 1728, in the small Yorkshire town of Marton. Unlike the majority of naval officers of the time he was not the son of rich or noble parents. In fact he was the son of a Scottish farm laborer and a Yorkshire girl. He was intelligent enough to impress his father's employer who paid for the young James Cook's schooling. After he finished school his parentsapprenticed(使……做学徒)him to a grocer(杂货商)in whitby, where he was notespecially happy. It was there, however, that he got a taste for life on the sea. In those days the port of Whitby was a bustling place, always busy with all kinds of

He said he was having a good time. He commented on(评论) the weather here and asked about the weather back there. While he was talking, he was eating a sandwich and drinking coffee.     

Method of Precise Auto Tool Setting for Micro Milling

Based on microscope and image processing, a new method of auto tool setting for micro milling was presented. Firstly, a realtime image of tool setting area was obtained by microscope and CCD camera, then image processing was carried out on this image and the gap between the tool and workpiece was calculated. The gap measurement was sent to motion controlling card to make the tool approach to the surface of workpiece. These steps were repeated until the gap is zero, which means that tool setting was finished. Moreover, a reliability verification test was conducted. Results indicated that the precision of tool setting is satisfactory.

A novel wide-range precision instrument for measuring three-dimensional surface topography

We developed a measuring instrument that had wide range, high precision, small measuring touch force. The instrument for three-dimensional （3D） surface topography measurement was composed of a high precision displacement sensor based on the Michelson interference principle, a 3D platform based on vertical scanning, a measuring and control circuit, and an industrial control computer. It was a closed loop control system, which changed the traditional moving stylus scanning style into a moving platform scanning style. When the workpiece was measured, the lever of the displacement sensor returned to the balanced position in every sample interval according to the zero offset of the displacement sensor. The non-linear error caused by the rotation of the lever was, therefore, very small even if the measuring range was wide. The instrument can measure the roughness and the profile size of a curved surface.
