investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
On the light side of geometric graphs
Let G be a geometric graph on n vertices in general position in the plane. Suppose that for every line ` in the plane the subgraph of G induced by the set of vertices in one of the two half-planes bounded by ` has at most k edges (k ≥ 1 may be a function of n). Then G has at most O(n √ k) edges. This bound is best possible.
متن کاملThe LHC, shining light on the Dark Side
Starting in the summer of 2007, the Large Hadron Collider (LHC) will collide proton beams at center-of-mass energies of 14 TeV exceeding by a factor of ten what was previously achieved. It will be located in the 27km long underground tunnel, in which the Large Electron Positron collider (LEP) was working until the year 2000. The Large Hadron Collider is a part of the accelerator complex of the ...

متن کاملUpdate on Red-Light Sensing The Red Side of Photomorphogenesis
The importance of light to normal plant growth and development cannot be overstated. As sessile photoautotrophs, plants depend on efficient light capture to compete and reproduce successfully within a relatively restricted geographical realm. For this purpose, these organisms have evolved very sophisticated sensory networks for monitoring the status of several important features of their illumi...
