On initial conditions and global existence for accelerating cosmologies from string theory [PDF]

, 2005
We construct a solution satisfying initial conditions for accelerating cosmologies from string/M-theory. Gowdy symmetric spacetimes with a positive potential are considered.

DYNAMICAL BEHAVIOR OF AN AXIALLY MOVING STRING CONSTITUTED BY A FRACTIONAL DIFFERENTIATION LAW

In this paper, the dynamical behavior of an axially moving string modeled by fractional derivative is investigated. The governing equation represented motion is solved by the method of multiple scales.

Parametric vibrations and stability of an axially moving 3-D string guided by a non-linear elastic foundation

, 2018
碩士本文研究分析軸向運動弦線造成之側向及橫向穩定性的分析及各種參數對於系統振動之影響。本研究主體係以三個自由度的軸向運動橫向振動為主之傳送系統，此系統之運輸帶以一三維之彈性弦線取代並簡化之。而傳輸系統架設在一個不斷有軸向速度的情況下，使此弦線不會因停滯而產生Gyroscope效應的影響。本弦線主體下方以彈簧做為支撐，模擬此弦線置放於elastic foundation 之情況。 吾人使用Lagrange法，分別考量弦線之動能及位能。此外，由於我們考慮的弦線系統假設是一個軸向移動之弦線，其兩端以滾輪固定 ...
