Abstract
With diffusion tensor imaging, the diffusion of water molecules through brain structures is quantified by parameters, which are estimated assuming monoexponential diffusion-weighted signal attenua... | |
# Boundary of boundary of closed set equals boundary of this set
I want to prove that for a closet set $A\subset \mathbb{R}^n$, $\partial A = \partial(\partial A)$. I've already proved that for an arbitrary subset $B$ of $\mathbb{R}^n$, $\partial(\partial B)\subseteq \partial B$ by arriving at the fact that $\partial ... | |
# Newton’s Method for Polynomials
Posted on April 14, 2018
Newton’s Methods is a useful tool for finding the roots of real-valued, differentiable functions. A drawback of the method is its dependence on the initial guess. For example, all roots of a 10th degree polynomial could be found with 10 very good guess. Howev... | |
# Embedding a Riemannian manifold with boundary in a closed manifold
Let $$M$$ be a complete Riemannian manifold of finite volume, with sectional curvatures bounded by some $$K>0$$ in absolute value. Let $$M_{\geq R}$$ be the set of points in $$M$$ with injectivity radius $$\geq R$$, that is the set of points $$x\in M... | |

I got blender into a somewhat strange state after I decided to add some vertex colours to my sculpt for better visibility.
As I load the save file I cannot paint the face sets anymore, not can I paint the mask. 'Invert mask' would do nothing.

Enter the maximum displacement, spring constant, and mass into the calculator to determine the spring velocity.
## Spring Velocity Formula
The following equation is used to calculate the Spring Velocity.
Vs = SQRT ( k*x^2 / m)
• Where Vs is the spring velocity (m/s)
• k is the spring constant (N/m)
• x is the maximu... | |
