Program Plan Intro
Cycles per element (CPE):
- The CPE denotes performance of program that helps in improving code.
- It helps to understand detailed level loop performance for an iterative program.
- It is appropriate for programs that use a repetitive computation.
- The processor’s activity sequencing is controlled by a clock that provides regular signal of some frequency.

2. RADIOACTIVE DECAY, REVISITED
This is a modified version of chapter 1 problem 4 in your textbook. Consider the radioactive decay of nuclei A into
nuclei B, which can then also decay. The numbers of each species as a function of time are given by N₁ (t) and NB (t),
and the decay of each species is governed by¹:

- PLEASE CODE IN PYTHON Problem Description:In order to ensure peace and prosperity for future generations, the United Nations is creating the world’s largest candy. The ingredients must be taken in railway cars from the top of a mountain and poured into Lake Geneva. The railway system goes steeply from the mountaintop down to the lake, with a T-shaped branch in the middle as shown below. Right now, each of the N ingredients is in its own railway car. Each railway car is assigned a positive integer from 1 to N. The ingredients must be poured into the lake in the order 1, 2, 3, . . . , N but the railway cars are lined up in some random order. The difficulty is that, because of the especially heavy gravity today, you can only move cars downhill to the lake, or sideways on the branch line. Is it still possible to pour the ingredients into the lake in the order 1, 2, 3, . . . , N ? For example, if the cars were in the order 2, 3, 1, 4, we can slide these into the lake in order as described…arrow_forwardQ1) Simplify the following Boolean functions using Karnaugh map method: A.

It is a non-conservative oscillator with nonlinear damping, modelled by the differential equation x” − µ(1 − x²)x′ + x = 0, where the parameter μ measures the strength of the nonlinear damping. (5.9) (1) Rewrite Equation (5.9) as a system of two first-order ODEs for x and x'. Then, write a Python function vdp(x) which returns the vector f(x), as defined in (5.1), for the Van der Pol system. Here, x must be an array of "shape" [1,2]. (2) Solve the Van der Pol system with µ = 1/2, using your Python functions rk4 and vdp, for t = [0, 30], starting with initial conditions (i) x(0) = x'(0) = 0.1; and (ii) x(0) = −2,x'(0) = 2. (You should fix a suitable step size, h.) Then, plot time series, x(t), of the solutions (i) and (ii) in one figure, and plot phase portraits, (x(t), y(t)), for the two solutions, in another figure.…arrow_forward

The jobs can be executed in any order, one job at a time. You want to find a schedule that minimizes the total time spent by all the jobs in the system. (The time spent by one job in the system is the sum of the time spent by this job in waiting plus the time spent on its execution.) Design a greedy algorithm for this problem. Does the greedy algorithm always yield an optimal solution? (Hint: You may get a clue from Prim’s Algorithm)arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
