Stability Problem of the Mass, Spring, Fluid System

the problem of divine hiddenness

این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...

Stability Analysis of Filtered Mass-Spring Systems

Mass-spring systems simulations rely on the numerical integration method used for solving the resulting ordinary differential equations. Implicit schemes, which solve such equations, are unconditionally stable and are thus widely used. Part of this stability is due to force filtering which is inherent to the implicit formulation and is referred to artificial damping. We extract this artificial ...

Notes on the Virtual Spring Mass System

A force feedback system, such as the haptic wheel used in the EECS 461 lab, is capable of exhibiting a wide range of interesting phenomena. It is useful to remember that the system consists of a mechanical device (the wheel in our case), with two feedback loops wrapped around it. As shown in Figure 1, one feedback loop consists of (i) a sensor such as an encoder, tachometer, or strain gauge, (i...

Periodic Motion of a Mass-Spring System

The equations of planar motion of a mass attached to two anchored massless springs form a symmetric Hamiltonian system. The system has a single dimensionless parameter L, corresponding to the spacing between the anchors. For L > 1, there is a stable equilibrium at which the springs are in tension and lie on a line, but for L < 1, this equilibrium has both springs in compression, and is unstable...
