Where a numerical value is necessary,take the acceleration due to gravity to be10m s−2.At the end of the examination,fasten all your work securely together.The number of marks is given in brackets[]at the end of each question or part question.The use of a calculator is expected,where ...
A particle A of unit mass travels horizontally through a viscous medium. When t = 0, the particle is at point O with initial speed u. The resistance on particle A due to the medium is kv2, where v is the velocity of the particle at time t and k is a positive constant.When t=0,...
In contrast to a vertically vibrated particle, for which chattering is claimed to be the generic fate, the horizontally shaken particle can become trapped on a periodic orbit and follow the period-doubling route to chaos when the coefficient of restitution is changed. We also discuss the case ...
,Endoh Sh,Gyenis J.摘要: Yangtze Region of China has high temperature in summer and low temperature in winter, with high humidity most of the year. The conventional household air conditioner cannot control temperature and humidity separately. Recently, the research on temperature and humidity ...
10 was installed and fixed horizontally on the test platform. In order to ensure that the hypothetical conditions of the simulation were matched with the experimental conditions, some crucial factors, including the nozzle structure, working pressure, fluid media and working conditions, were kept ...
Despite drastic cellular changes during cleavage, a mitotic spindle assembles in each blastomere to accurately segregate duplicated chromosomes. Mechanisms of mitotic spindle assembly have been extensively studied using small somatic cells. However, mech
because the location of the NFC is considered to be just above the DC from the results of the detectors installed in the DC. The projected direction was determined by making the histogram of a cross section of the angular distribution, which is perpendicular to the longitudinal direction (north...
PURPOSE: To absolutely measure the particle density of an extremely thin gas. ;CONSTITUTION: A gas particle is ionized 100% by a laser beam 11. An ion generating space S is projected on a two-dimensional phosphor scree 19. The length L and width W of the two-dimensional area regarded to...
In this study, novel image-based algorithm that can be used to identify shapes of input images and at the same time classify non-uniform deformation into various patterns, i.e., swelling/shrinkage, horizontal and vertical elongations/contractions as well as convexity and concavity, is proposed....
For example, to understand the fluid-structure interaction behavior of a square cylinder with corner fins, it is suggested to perform aeroelastic tests in a wind tunnel or conduct numerical simulations with moving mesh. On the other hand, advanced experimental techniques, e.g. particle image ...
