Cuomo Is Eating De Blasio's Lunch On Congestion Pricing

Governor Andrew Cuomo made congestion pricing a centerpiece of his budget presentation earlier this month, pledging to raise $15 billion for transit improvements by tolling vehicles crossing bridges into Manhattan or traveling below 60th Street in Manhattan. According to a recent poll, 52 percent of New York State residents support congestion pricing, and that number climbs even higher for those living in the city. Missing from the conversation: Mayor Bill de Blasio, who at first said he did not "believe" in congestion pricing, and now says that the idea to toll cars coming into his city has nothing to do with him.

Solving Van der Pol equation with ivp_solve

Van der Pol’s differential equation is The equation describes a system with nonlinear damping, the degree of damping given by μ. If μ = 0 the system is linear and undamped, but for positive μ the system is nonlinear and damped. We will plot the phase portrait for the solution to Van der Pol’s equation in Python using SciPy’s new ODE solver ivp_solve . The function ivp_solve does not solve second-order systems of equations directly. It solves systems of first-order equations, but a second-order differential equation can be recast as a pair of first-order equations by introducing the first derivative as a new variable. Since y is the derivative of x , the phase portrait is just the plot of ( x , y ). If μ = 0, we have a simple harmonic oscillator and the phase portrait is simply a circle. For larger values of μ the solutions enter limiting cycles, but the cycles are more complicated than just circles. Here’s the Python code that made the plot. from scipy import linspace from ...

Lawyer: 'Socialite Grifter' Anna Sorokin 'Had To Do It Her Way' (And Steal $275,000)

Opening statements were made in the "Socialite Grifter" trial on Wednesday, and both sides provided extremely different reasons why Anna Sorokin allegedly scammed a number of people and institutions out of $275,000. [ more › ] Gothamist https://ift.tt/2HXgI0E March 29, 2019 at 12:33AM

Photos: Miss Subways Crowned After Drinking A 'Vial Of Cuomo's Tears'

After a particularly dramatic primary that focused a lot on NYC's (crumbling) mass transit , it was fitting that the new Miss Subways invoked Governor Cuomo—and his challenger after winning the title last night. [ more › ] Gothamist https://ift.tt/2R2bqmJ September 28, 2018 at 10:13PM
