I want to run several shocks in my calibrated DSGE model. I want the shock “a” to happen at period 0, shock “b” at period 2 and shock “c” at period 5. Also, I want to run a shock of 1 % to the variable “a”, 2 % to variable “b” and 10 % to variable “c”. How would I write it in the Dynare code? The model is log-linearized around the steady state and all endogenous variables are set at 0 at the steady state.

PIoVide ue comect u We want to design an experiment to measure oscillations of a simple pendulum on the surface of Jupiter with acceleration due to gravity g= 30 ms 2. We have to make do with a rudimentary video camera with a frame rate of 15 Hz to record oscillations in a pendulum and use it to measure the frequency of oscillation. The smallest length of the pendulum that we can send so that the correct oscillation frequency can be measured is cm. Assume perfect spatial resolution of the camera and ignore other "minor" logistical difficulties with this experiment.

I1 Give an example how it is applied in molecular dynamics simulation and Monte carlo simulation? Typical distributions of particles in a volume (e.g. crystal structure for a solid, or distribution of masses and velocities in a “typical” galaxy) - Distributions of particle velocities/energies (e.g. Boltzmann distribution at a fixed temperature) - E.g. for a liquid it is common to start with a solid crystal structure and let the structure “melt” (by setting appropriate velocities corresponding to the liquid phase temperature!)   - E.g. to setup a collision of two galaxies, you could try to generate a stable distribution of masses and velocities for a single galaxy first by performing a separate simulation -E.g. A simple model of a phase transition between a low temperature ordered phase (ferromagnet) and high temperature disordered phase (paramagnet) whats the difference in phase space in Molecular dynamics and Monte Carlo simulation?

2.1.28. [Level 2] In the year 2137 a hovering spacecraft releases a probe in the atmosphere far above the surface of New Earth, a planet orbiting Alpha Proximi. The gravita- tional acceleration g1 is constant and equal to 7.5 m/s?. How far will the probe have traveled when it has reached 98% of its terminal speed? The probe's speed is governed by ÿ = -g1 + cy where y is the probe's position above the planet's surface (expressed in m). c = 1.2 × 10-4 m-1.

The center of mass for a human body can be determined by a segmental method. Using cadavers, it is possible to determine the mass of individual body segments (as a proportion of total body mass) and the center of mass for each segment (often expressed as a distance from one end of the segment). Finding the overall body center of mass can be a complex calculation, involving more than 10 body segments. Below, we will look at a simplified model that uses just six segments: head, trunk, two arms, and two legs. Search y X As a percentage of total body mass, the head is 10%, the two arms are 10%, the trunk is 56%, and the two legs are 24%. The center of mass for each segment is given as an (x,y) coordinate, both units in cm: head = (0, 165), arms = (0, 115), trunk = (0, 95), and legs = (0, 35). Assume the body mass for the individual is 88 kg and their total height is 180 cm. Determine they and y coord 99+ H of mass

Harmonic oscillators. One of the simplest yet most important second-order, linear, constant- coefficient differential equations is the equation for a harmonic oscilator. This equation models the motion of a mass attached to a spring. The spring is attached to a vertical wall and the mass is allowed to slide along a horizontal track. We let z denote the displacement of the mass from its natural resting place (with x > 0 if the spring is stretched and x 0 is the damping constant, and k> 0 is the spring constant. Newton's law states that the force acting on the oscillator is equal to mass times acceleration. Therefore the differential equation for the damped harmonic oscillator is mx" + bx' + kr = 0.
