I'm working on a fivem script
I am currently using this code to check if both teams have players in them is there a more optimal way?
local teams = {['A']= 0, ['B']= 0}
Citizen.CreateThread(function()
while true do
print(teams['A'])
print(teams['B'])
if teams['A'] ~= 0 and teams['B'] ~= 0 then
print('triggered')
end
Citizen.Wait(1500)

Hi there.
Yesterday, I came to you with a following prompt:
"Hello! Let’s have a TS training session. I know the basics of JS and I am trying to learn TS as well. If you were to write a program in TS, I would try to read and understand it, and if I am ever stuck, I 'd just ask you about what I don’t understand. Can you do that? If you do, please write a somewhat short (10-40 lines long) program for me to analyze.
If you can, please make this program neither too basic or too complicated. Also, please do not explain what does it do and don’t add any comments. We’re pretending that this is a someone else’s code that we need to analyze, and someone else’s code would most likely not have comments and we’d have no one to explain the code to us.
We did this exercise a few times already, so please do not use the following examples:
Simple Person class with Greetings method;
Simple shopping cart program" (end of prompt quote)
You were able to come up with a program, but we didn't have enough time to break it down. Can I copy the program you suggested here so I can analyze it in this new chat?

we are going to develop a project with dataset of satellite images before and after an earthquake. We are going to use Yolov8. The thing is I can not understand how we are going to use both the before image and after image of disaster. Yolov8 is object detection model so it gets trained on only a type of image. I really don't know what we are going to predict given this dataset ? May be the probability of destruction ? If so how are we going to train Yolov8 models. Can you help me, please give detailed explanation I am really confused.

I’m working on a rust program. Why should the id variable have an option, such as : pub id: option<AccountId>
Here is the code:
use serde::{Deserialize, Serialize};
#[derive(Serialize, Deserialize, Debug, Clone)]
pub struct Account {
pub id: option<AccountId>,
pub email: String,
pub password: String,
}
#[derive(Deserialize, Serialize, Debug, Clone, PartialEq, Eq, Hash)] pub struct AccountId(pub i32);
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct NewAccount {
pub email: String,
pub password: String,
}

can you change it so that the player can give both the name of the artist or the number 1 or 2, not every artist should have their own number

давайте напишем наш градиентный спуск. Напомним, что формула для одной итерации градиентного спуска выглядит следующим образом:
$$
w^t = w^{t-1} - \eta \nabla_{w} Q(w^{t-1}, X, y)
$$
Где $w^t$ — значение вектора весов на $t$-ой итерации, а $\eta$ — параметр learning rate, отвечающий за размер шага.
Реализуйте функцию gradient_descent
Функция должна принимать на вход начальное значение весов линейной модели w_init, матрицу объектов-признаков X, вектор правильных ответов y, объект функции потерь loss, размер шага lr и количество итераций n_iterations.
Функция должна реализовывать цикл, в котором происходит шаг градиентного спуска (градиенты берутся из loss посредством вызова метода calc_grad) по формуле выше и возвращать траекторию спуска (список из новых значений весов на каждом шаге)
def gradient_descent(
w_init: np.ndarray,
X: np.ndarray,
y: np.ndarray,
loss: BaseLoss,
lr: float,
n_iterations: int = 100000,
) -> List[np.ndarray]:
"""
Функция градиентного спуска
:param w_init: np.ndarray размера (n_feratures,) -- начальное значение вектора весов
:param X: np.ndarray размера (n_objects, n_features) -- матрица объекты-признаки
:param y: np.ndarray размера (n_objects,) -- вектор правильных ответов
:param loss: Объект подкласса BaseLoss, который умеет считать градиенты при помощи loss.calc_grad(X, y, w)
:param lr: float -- параметр величины шага, на который нужно домножать градиент
:param n_iterations: int -- сколько итераций делать
:return: Список из n_iterations объектов np.ndarray размера (n_features,) -- история весов на каждом шаге

how can i change it so you can choose between different genres of music to play the game, for example the game explains what genres you can pick and then it only asks questions of artitsts in that genre, do i need to make a different set of data ? You dont need to correct the code

Сделайте и опишите свои выводы о том, как параметры lr и batch_size влияют на поведение стохастического градиентного спуска. Как отличается поведение стохастического градиентного спуска от обычного?
Обратите внимание, что в нашем датасете всего 300 объектов, так что batch_size больше этого числа не будет иметь смысла.

Ok, working with single database is pretty simple, what if you have 2 or more storages? It might be not only databases, but external REST CRUD services or message queues.
And it is possible that one of that external storage have no option to rollback or made revers changes.
What is possible approaches here?
As an example you might refer to next:

In groups of 5-6 students, you are required to design and implement a database to
address the requirements of a scenario provided by your tutor. Note that you will be
grouped with other students in the same seminar session.
As the scenario contains only a brief outline of a business case study, you will need to
state any business rules and assumptions that you have made in order to fill any gaps or
to address any ambiguities when putting together your database design. All the required
tables need to be implemented using Oracle APEX.
SUBMISSION A: Group Project Report
Each group member needs to submit a copy of their group’s report using the ‘ISDB
Group Project’ submission link set up on Blackboard. Any group member who fails to
submit a copy will be awarded zero marks. Any report that is submitted late will capped
at 40%. The report must use the assignment report template provided, containing the
following elements, in this order:
1. A header page which includes the name and ID of your team members and the
username and password of the APEX account(s) containing your group’s
implemented tables and reports/queries.
2. A list of any assumptions/clarifications you have made that have affected the
design of your database.
3. An ER diagram (using ‘Crow’s foot’ notation) providing the final design of your
database, which shows entities, attributes, primary and foreign keys, and named
relationships.
4. Entity specification forms documenting all your entities (using the template
provided).
5. The SQL scripts you used to create your tables (including all constraints) which
should match your entity specification forms.
6. A list of the SQL scripts (INSERT INTO ..commands) used to insert test data into
each of your tables, annotated to show that there is sufficient breadth and
volume of data to adequately test your queries/reports (see below).
2
7. 8 functional requirements generating reports/output that effectively
demonstrate the scope and functionality of the system, and for each: a) the SQL
script used to implement the requirement, and b) a screenshot of the run query
and output it produces. The queries you choose should critical queries illustrating
the breadth and potential of the implemented database, as well as your mastery
of SQL. Each script should be numbered and saved in your database.
8. A brief overview of the database features you would implement to ensure your
data is adequately secured.
9. A suggestion for one other database technology/information system that you
think might benefit the company, either now or in the future, providing a
rationale for this.
10. Evidence to show effective and timely project management using Scrum, the
contribution of each member to the project, namely attendance at team
meetings held in (and outside) your seminar sessions, sprint backlogs, tasks
uploaded to the group’s file Blackboard area and SQL scripts saved in members’
APEX account(s). Case study for Information Systems and Databases – February 2023
South London University’s Computing school wishes to set up a database to manage its external
speaker and placements processes. This is all part of developing links with local businesses and
giving students the opportunity to get some industry experience.
At present, individual members of the teaching team organise guest lectures, but this is all done in a
rather random fashion. They might use their personal contacts or meet an interesting speaker at an
external event and invite him/her to give a lecture or run a workshop for their students. If the
speaker agrees, then the lecturer will contact the timetabling unit to arrange a suitable date, time
and room for the lecture and then announce details of the event through the Blackboard
announcement system.
With the increasing emphasis on giving students ‘real world’ experiences, more and more of these
events are being run and the school wishes to make the most of the contacts they have and which
topics these contacts have expressed an interest in talking about. Unfortunately, these contacts and
speakers are not stored centrally, which leads to problems, for example:
• There have been occasions where multiple guest lectures have been arranged in one week
for a particular cohort of students, as each of the teaching staff concerned had no idea of
the other lecturers’ arrangements.
• A number of guest lectures were arranged on the same topic, thereby duplicating the
content of a previous lecture.
• Staff have independently invited speakers from the same company.
• Staff members have contacted an organisation to ask if it would consider offering
placement/workshop/ guest lecture etc, to find that the contact has already been
approached and has turned down the request - so is annoyed that he/she is being targeted
again.
• Staff members wanted to re-run specific guest lectures in a subsequent year for a new
cohort of students, but the staff member who had arranged the original lecture had left the
university without leaving details of the contact.
• Students have turned up to the staff room wanting to know where a lecture was being held.
etc.. etc..
The school is very keen to set up a database as it feels that if everything is centrally stored it will be
able eradicate such problems and to use the contacts to greater advantage, for example to see if a
speaker (or someone within their organisation) would be interested in providing placements/job
experience or live projects for students, as well as guest lectures. The Head of School hopes that a
sensible timetable can be put together showing the guest lectures for the whole of a semester which
students and teaching staff could access. He would also like to monitor attendance at each of the
lectures/workshops and also to collect any positive or negative feedback from students to see how
popular the talk has been, which might indicate whether to re-run a particular talk the following
year.
5
The Head of Computing has suggested that, with a new system, teaching staff could put in requests
for a guest lecture on a particular topic, and the system administrator might then be able to suggest
a suitable external speaker for that topic from information held in the database.
A small number of companies are already supplying ‘live’ projects to the department and the Head
of School hopes that a lot more can be found. The details of these also need to be stored centrally,
together with the member of staff who is running the live project. At present nobody knows who is
doing what. The marketing manager for the school would also like to know about these live projects
and their outcomes – if completed successfully, they could raise some good publicity for the
university. The new system should have some mechanism for informing the marketing manager that
the project has completed so that timely publicity materials can be produced.
The Head of School would also like there to be a designated staff member for each organisation,
responsible for nurturing and developing links with the organisation. Anyone wishing to contact a
company would need to liaise with the designated staff contact person. Members of staff should
have easy access to this information. The system should also be able to store a history of the
contacts made with each company and the reason for that contact, which teaching staff could refer
to.
The placement officer for the school also wants to maintain a database of placement or job
experience opportunities provided by organisations, and which students have been successful in
getting these placements, so that these students could be invited to talk to the student cohort on
their return from placement – again this is all part of getting students ready for the world of work.
School administrators will also benefit from this as currently they often unaware of which students
are doing placements. The new system will be able to clearly show which students are on placement
and who their designated supervisor is at their placement company (which may be different for each
student).
The Head of School and administrator think that useful reports could be generated from the
proposed database, for example to show how the school is interacting with businesses and the local
community, which lecturer has made the most effort at developing links with industry (and who
hasn’t bothered at all…), and many other outputs.
All in all, the current system is a mess and you have been called in to sort it out. The above
description is just a basic outline of some of the issues and problems. You can make any sensible
assumptions to fill in any gaps. Good luck!

In this problem, you are working in chemical sales, selling a compound that is used to make batteries. This compound requires a couple of ingredients, which has been stored in structure array "ingredients". You have also been storing some of your past compound orders in anothe rstructure array "orders", but you realize you never noted down how much of each ingredient you use. It is your task to dtermine whether you can solve for the amount of ingredients used for each order, and return the solution, if you can. "ingredients" is a structure array the following information (table) in each of its fields:
field value
price cost of buying this ingredient
mass mass of this ingredient
The structure array will contain "N" ingredients elements, all of which are used together to create a singular compound (e.g. if there are 2 elements in "ingredients", then they are used together to create 1 chemical compund)
"order" contains information (table) about some orders you had for this chemical compound:
field value
weight total mass of the order
cost total cost of fulfilling the order
This structure array contains 1 order for the compound created from combining all the ingredients. With the information you are given, construct a system with the following form: Ax=b where "x" is the amount of each ingredient that you used in the orders. You will try to solve for "x" in this problem. First, you must analyze the system to see what type of solution you will get. There are 3 possibilities: 'Unique', 'Infinite', and 'None'. Once you have determined this, assign this to "num_solutions", and proceed with solving the solution. Notice that "A\b" will still return some value for infinite and no solutions. Tips you have to use: "rref()" cannot be used in the solution in matlab. You are given the following code just fill it in:
function [num_solutions,solution] = analyzeSales(ingredients, order)

for round 1 “Do you want to follow? [Y/N]:” is not needed. Display current amount bet by player or dealer depending whose most recent card is bigger by displaying “Dealer/Player call, state bet:”. Ask for betting input after player calls if the player’s most recent card is bigger than the dealer. Remove max bet. Chips bet cannot be negative. If chips are insufficient, notify the player and display message “Chips insufficient” and let the player enter bet again.

Ask player to call or quit before asking state bet. Dealer same as player in the whole game cannot spend past 100 chips in bets. Dealer's hidden card is hidden during the game and is only revealed after round 4 when the game ends.

In this problem, we are going to obtain the best fit regression model by comparing non-linear model with linear models of varying order using least-squares criterion.
Linear model: y=(a_m)x^m+(a_m-1)x^(m-1)+a1x+a0
Non-linear model: y=ce^bx
For the function "regression", there are three inputs: "xval", y_val", and "m", which is the maximum order of the linear model. You need to find the best model among linear models (of different orders from 1 to "m") and non-linear model based on the least value of "RMSE", which is defined as:
RMSE=sqrt(1/n*summation i=1 ((y^i)-yi)^2) where (y^i) is the estimation of of y. For example: if 2nd order linear model is the best fit (having the least value of RMSE) then the output variable "best_fit" = 'linear-2'.You have to describe different models in the structure array "details" and plot both models along with the given data to visualize the best fit model. For better understanding, see the given test case. Tips you have to use: Your function should work on any set of data in the appropriate format. For the non-linear model, the relationship between "x" and "y" can be linearized by taking the logarithmic on both sides: logy=logc+bx. But "details(2).coefs" must contain the values of "b" and "c" respectively. For the "coefs" field in case of linear models, arrange the coefficients of each models such that the coefficients of higher order terms should come first.You can use "sprintf()" function. Test case:
xval = 1:5;
yval = exp(xval);
m = 2;
[fig, best_fit, details] = regression(xval, yval, m)
fig =
Figure (1) with properties:
Number: 1
Name: ' '
Color: [0.9400 0.9400 0.9400]
Position: [488 342 560 420]
Units 'pixels'
best_fit =
"non-linear"
details =
1x2 struct array with fields:
model
order
coefs
RMSE
details(1) ans =
struct with fields:
model: 'linear'
order: [1 2]
coefs: {2x1 cell}
RMSE: [25.0243 7.3614]
details(2) ans =
struct with fields:
model: 'non-linear'
order: 'n/a'
coefs: [1.0000 1]
RMSE: 7.2292e-16
details(1).coefs ans =
2x1 cell array
{[33.8599 -54.9388]}
{[14.2932 -51.8992 45.1135]}
You are given the following code in matlab just fill it in:
function [fig, best_fit, details] = regression(xval, yval, m)
% Linear model
% Non-linear model
% RMSE comparison
fig = figure;
xvals = linspace(min(xval),max(xval),50); % use this array to predict y for plotting
% follow the order: raw data, linear-1, linear-2, ...., linear-m, non-linear
axis([min(xval) max(xval) min(yval) max(yval)]) % axis limits
end

make the following changes to this HTML and CSS files:
remove the title from every html page instead make the header format be Logo(left side)------Title Page (in the centre)--------navigation bar(left)
make the changes so that they look equally spaced, also make sure you change the fact that in the header navigation bar is a row under the title
also this is where you can find my logo it is in svg

In this problem, we are going to obtain the best fit regression model by comparing non-linear model with linear models of varying order using least-squares criterion.
Linear model: y=(a_m)x^m+(a_m-1)x^(m-1)+a1x+a0
Non-linear model: y=ce^bx
For the function "regression", there are three inputs: "xval", y_val", and "m", which is the maximum order of the linear model. You need to find the best model among linear models (of different orders from 1 to "m") and non-linear model based on the least value of "RMSE", which is defined as:
RMSE=sqrt(1/n*summation i=1 ((y^i)-yi)^2) where (y^i) is the estimation of of y. For example: if 2nd order linear model is the best fit (having the least value of RMSE) then the output variable "best_fit" = 'linear-2'.You have to describe different models in the structure array "details" and plot both models along with the given data to visualize the best fit model. For better understanding, see the given test case. Tips you have to use: Your function should work on any set of data in the appropriate format. For the non-linear model, the relationship between "x" and "y" can be linearized by taking the logarithmic on both sides: logy=logc+bx. But "details(2).coefs" must contain the values of "b" and "c" respectively. For the "coefs" field in case of linear models, arrange the coefficients of each models such that the coefficients of higher order terms should come first.You can use "sprintf()" function. Test case:
xval = 1:5;
yval = exp(xval);
m = 2;
[fig, best_fit, details] = regression(xval, yval, m)
fig =
Figure (1) with properties:
Number: 1
Name: ' '
Color: [0.9400 0.9400 0.9400]
Position: [488 342 560 420]
Units 'pixels'
best_fit =
"non-linear"
details =
1x2 struct array with fields:
model
order
coefs
RMSE
details(1) ans =
struct with fields:
model: 'linear'
order: [1 2]
coefs: {2x1 cell}
RMSE: [25.0243 7.3614]
details(2) ans =
struct with fields:
model: 'non-linear'
order: 'n/a'
coefs: [1.0000 1]
RMSE: 7.2292e-16
details(1).coefs ans =
2x1 cell array
{[33.8599 -54.9388]}
{[14.2932 -51.8992 45.1135]}
You are given the following code in matlab just fill it in:
function [fig, best_fit, details] = regression(xval, yval, m)
% Linear model
% Non-linear model
% RMSE comparison
fig = figure;
xvals = linspace(min(xval),max(xval),50); % use this array to predict y for plotting
% follow the order: raw data, linear-1, linear-2, ...., linear-m, non-linear
axis([min(xval) max(xval) min(yval) max(yval)]) % axis limits
end
Here is the code I will use to call my function: xval = 1:5;
yval = exp(xval);
m=2;
[fig, best_fit, details] = regression(xval, yval, m)

using Turings reaction diffusion model create a mathematical model for human population growth, where the reaction is population and the diffusion is information. When population increases then information increases then population increases. If population is approaching the carrying capacity then information increase causes slowing down of population increase

Terminology
State Variables
In a dynamical system (such as an Initial Value Problem), the dependent variables are also called the state variables. e.g., in Problem 5 of HW #9, x and v (or ẋ) are the state variables. These variables are often put into an array, which is called the state array. While the independent variable (usually time, for us) is not technically considered a state variable, we are primarily interested in the system state as a function of time. In our case, we will insert the independent variable as the first value in the state array and call it the augmented state array.
Mode Shapes and Natural Frequencies
Consider the vibration system below. As a two degree of freedom system, it has two natural frequencies and two mode shapes. If the two masses are both displaced to the left (by the correct distances) and released, they will each undergo perfect sinusoidal motion. Both will oscillate at the same frequency – called the first natural frequency. The first mode shape is a normalized vector representing respective signed amplitudes of their oscillations. The second mode shape and second natural frequency occur when the two masses are released after being displaced (by the correct distances) in opposite directions. In this case, the values in the mode shapes will have different signs, because the masses are moving in opposite directions.
Task #1
Write a single function script to perform the Third Order Adams-Bashforth-Moulton algorithm on a system of ordinary differential equations (IVP). The program must be able to handle any number of differential equations (an IVP with any number of state variables).
Your function m-file will receive through its header the following problem parameters (in this
exact order):
a. a cell array containing the function handles of the equations describing the time derivatives of the several state variables
b. the initial augmented state-array – a numerical row array containing the needed starting values of the independent variable and the several state variables (in the same order as the function handles in the cell array from the first input argument)
c. the step size to be used, and
d. the number of steps to take
Function Output
Your file should not return anything to the calling program. Instead, it should
i. print to screen (the command window) the final state of the system, including t, and
ii. plot a trace for each of the dependent variables as a function of time.
Plot each trace on a separate graph. To facilitate plotting, store the results of all time steps in the augmented state-array
a. each row represents the system at a different point in time
b. column 1 contains the time, and each other column contains the temporal history of a particular state variable
Store only the final result of each time step, not the predicted or non-converged corrected values. Title each plot ‘Var1’, ‘Var2’, etc. Try help plot and help title in the MATLAB command window to learn more about plotting. num2str will also be useful for creating the labels themselves.
Hints for your Function Script
Handling a System of Un-predetermined Size
Technical
Because you will not know in advance the order of the IVP your function will be asked to solve, some of the system parameters will need to be passed in as arrays, rather than as scalars. The step size and number of steps will still be scalars, but there will be an un-predetermined number of state variables, each of which will have an associated starting value and derivative expression. The starting value of each state variable is a scalar, so the collection of them can be stored in a normal array. On the other hand, your function script must be passed a separate function handle for the equation for the time derivative of each state variable. To store function handles, we must use a cell array. So then, you must be able to evaluate a function handle stored in a cell array. We did this in Lab #4, but I cover it again later in this document.
NOTE: Because your augmented state array will include time as the first value, the function stored in the nth index of the cell array is actually the derivative of the state variable in the (n+1)th index of the augmented state array.
Metaphysical
To figure out how to structure your code to deal with any size system, consult HW#9 and the notes from lab. In the HW, we performed RK3 on a 2nd order system. We can call the state variables x and v, and we can call their slopes (time derivatives) k and m, respectively. Feel free to write out and logically group the steps you took to solve the system for one timestep. Now, imagine we have 3 or 4 state variables each with their own slopes. Again, write out and logically group the steps you took to solve the system of equations. What changed about the process? Did the number of groups increase? Did the number of steps within particular groups increase? Now, we need to replace the RK4 algorithm steps with the ABM4 algorithm steps. Pay careful attention to the following differences:
a. the predictor and its modifier are performed once per time step, the corrector and its modifier are repeated until convergence each time step
b. the is no modifier on the predictor in the first time step
c. when performing the modifier steps, you use only non-modified values
d. when you check for convergence you compare only modified values
Function handles with unknown number of inputs
If you remember doing this for Modified Secant on a system of equations, then you may skip this section.
Up to now, you’ve probably only used function handles for equations that had a predetermined number of inputs. For this program, each derivative equation may be a function of the independent variable and any or all of the state variables. This is only a problem because you don’t know now (as you’re writing the function script) how many or which of the state variables will appear in each of the derivative equations. Fortunately, MATLAB allows us to put arrays into the equation function evaluation.
For example, if I define a function handle:
d1_by_dt = @(t,a) a(1) * a(3) / (2 + t);
when you ask MATLAB to evaluate the mathematical expression, MATLAB will expect to receive a scalar as the 1st argument, and an array of at least three terms as the 2nd argument. It will use the first and third terms in the array, along with the scalar, to evaluate the expression.
The augmented state array passed into the function already has t as the first value, so let’s just stick with that. Then our example equation becomes:
d1_by_dt = @(a) a(2) * a(4) / (2 + a(1));
You, of course, will have no prior knowledge of which state variables are used in each derivative expression. Therefore, for each derivative evaluation, you will need to submit an array containing the correct values of the dependent variable and all of the state variables, in the same order as the initial values in the passed-in augmented state array. When grading your code, it will be my responsibility to ensure that all of the derivative equations use the correct variables.
Function handles in cell arrays
The function handles of the derivative expressions of the several state variables will be passed to your function script in a cell array. The syntax for evaluating a function handle that is stored in a cell array is as follows:
value = array_name{n}(input1, input2, ... , inputQ)
• array_name is the name of the cell array in which the handles are stored
• n is the index into the cell array, in which is stored the expression for (d/dt)y n
• input1 thru inputQ are the inputs to the mathematical expression represented by the function handle – in our case that will simply be the augmented state array
Please note that those are braces around the index ‘n’ and parentheses around the arguments.
The ABM4 process
To calculate the predicted value of each state variable, you are going to perform very similar math:
n+1 ^0y k = n y k + h((55/24)g^k n - (59/24)g^k n-1 + (37/24)g^k n-2 - (3/8)g^k n-3)
where the k superscript on each g term matches the state variable number (the k subscript on each y term). Take advantage of how MATALB deals with vectors to simplify the process of calculating the predictor for all the state variable and each subsequent corrector for all the state variables. Create an array that holds the g m evaluations for all of the state variables. You will have 3 or 4 of these, one for each timestep. Then you can ...
temp_state = current_state + (h / 2) * slopes_array
Test your program
The spring-mass system from the Terminology section has been reproduced here.
Neglecting friction, the equations of motion of this system are:
ẍ1 = (-(k1+k2)x1 + k2x2)/m1
ẍ2 = (-(k2+k3)x2 + k2x1)/m2
where x1 and x2 are measured from the static equilibrium locations of the respective masses. To handle the 2nd order nature of the time derivatives, we must include additional state variables v1 and v2. If we arrange the state variables in the order x1, v1, x2, v2, the augmented state array becomes t, x1, v1, x2, v2, and the corresponding differential equations becomes:
dx1/dt = g1(a) = a(3)
dv1/dt = g2(a) = (-(k1+k2)a(2) + k2a(4))/m1
dx2/dt = g3(a) = a(5)
dv2/dt = g4(a) = (-(k2+k3)a(4) + k2a(2))/m2
Remember, a(1) is time, which does not appear in our equations of motion.
Create a main script (program) that performs the following tasks:
iii. define the system parameters (masses and spring stiffnesses)
iv. define the IVP functions above and store them in a cell array
v. set the initial condition of the augmented state array (time and all four state variables)
vi. call your RK4 function script
Set the system parameters to m1 = m2 = 1(kg) and k1 = k2 = k3 = 13.16(N/m). Set the initial
conditions to t = 0, x1(0) = 0.01(m), v1(0) = 0, x2(0) = -0.01(m), and v2(0) = 0. Call your RK4 function script with a time step of 0.001 seconds and 2000 time steps. Inspect the plots of x1 and x2. They should be mirrored sinusoidal functions with amplitudes of 0.01 and frequencies of 1Hz (2π rad/sec).
Analyze Your Custom Vibration System
You are going to customize the parameters of the spring mass system based upon your student ID number. Consider digits 4-5 as a two digit number X. Let digits 6-7 be a two digit number Y. If either X or Y are zero, pretend that they are 35.
Task #2: Apply Your Program
You will use your function to analyze a customized version of the vibration system depicted on the previous page. The system will be customized based on the last four digits of your student ID. Your goal will be to determine the second natural frequency and corresponding mode shape. For more details, refer to the Terminology section of this document.
Set the system parameters to m1 = 1(kg), m2 = (0.75-(X/200))(kg), k1 = k2 = 13.16(N/m), and k3 = (13.66+(Y/200))(N/m). Set the initial conditions to t = 0, x1(0) = -0.01(m), v1(0) = 0, and v2(0) = 0. Please note that the initial value of x1 is negative. Now, find the second natural frequency and second mode shape of your system by running your RK4 function multiple times, with different initial values for x2. I think the correct value should be > 0.01.
When you find the correct value of x2(0) each mass should demonstrate smooth sinusoidal motion. Inspect your table of state variables to determine the period of the oscillation. The period is the time between consecutive maximum displacements. The frequency in Hz is the inverse of the period. The mode shape is the vector [x1(0); x2(0)] scaled to have a Euclidean norm of unity (1).
Include in your Lab Report the following:
• the last four digits of your student ID number
• the values you used for X and Y
• the second natural frequency, in Hz, of your customized spring-mass system
• the normalized second mode shape of your customized spring-mass system
• plots of x1 and x2 as functions of time for two seconds
Provide the natural frequency and mode shape values to 5 significant figures.
Here is the RK4 chunk that is supposed to go on the top of the code for the function:
% In the code below:
%
% g is cell array containing the various dy/dt functions
%
% s_a is the augmented state array. It starts out as a row vector. It is
% passed in with the starting values of t and each state variable, in the
% same order as the function handles in the g cell array. It will
% eventually contain all of the values of t and the state variables over
% time.
%
% h is the step size
N = length(g);
slopes = zeros(4,N)
for iter = 1:2
state = s_a(iter,:);
for c = 1:N
slopes(1,c) = g{c}(state);
end
state = s_a(iter,:) + (h/2)*[1, slopes(1,:)];
for c = 1:N
slopes(2,c) = g{c}(state);
end
state = s_a(iter,:) + (h/2)*[1, slopes(2,:)];
for c = 1:N
slopes(3,c) = g{c}(state);
end
state = s_a(iter,:) + h*[1, slopes(3,:)];
for c = 1:N
slopes(4,c) = g{c}(state);
end
RK = (slopes(1,:) + 2*slopes(2,:) + 2*slopes(3,:) + slopes(4,:)) / 6;
s_a(iter+1,:) = s_a(iter,:) + h*[1, RK]
end
When this chunk is done, we should have three rows in the augmented state array, corresponding to our first three time points. It shouldn't be changed in any way while making the function script.

Deliverables
You will upload to Canvas a single .zip file, titled LastNameFirstInit_Lab8.zip, containing two separate files: 1) LastNameFirstInit_Lab8.m will contain your ABM4 code in response to Task 1, and 2) LastNameFirstInit_Lab8.pdf will contain your lab report in response to Task 2.
Terminology
State Variables
In a dynamical system (such as an Initial Value Problem), the dependent variables are also called the state variables. e.g., in Problem 5 of HW #9, x and v (or ẋ) are the state variables. These variables are often put into an array, which is called the state array. While the independent variable (usually time, for us) is not technically considered a state variable, we are primarily interested in the system state as a function of time. In our case, we will insert the independent variable as the first value in the state array and call it the augmented state array.
Mode Shapes and Natural Frequencies
Consider the vibration system below. As a two degree of freedom system, it has two natural frequencies and two mode shapes. If the two masses are both displaced to the left (by the correct distances) and released, they will each undergo perfect sinusoidal motion. Both will oscillate at the same frequency – called the first natural frequency. The first mode shape is a normalized vector representing respective signed amplitudes of their oscillations. The second mode shape and second natural frequency occur when the two masses are released after being displaced (by the correct distances) in opposite directions. In this case, the values in the mode shapes will have different signs, because the masses are moving in opposite directions.
Task #1
Write a single function script to perform the Fourth Order Adams-Bashforth-Moulton algorithm on a system of ordinary differential equations (IVP). The program must be able to handle any number of differential equations (an IVP with any number of state variables).
Your function m-file will receive through its header the following problem parameters (in this
exact order):
a. a cell array containing the function handles of the equations describing the time derivatives of the several state variables
b. the initial augmented state-array – a numerical row array containing the needed starting values of the independent variable and the several state variables (in the same order as the function handles in the cell array from the first input argument)
c. the step size to be used, and
d. the number of steps to take
Function Output
Your file should not return anything to the calling program. Instead, it should
i. print to screen (the command window) the final state of the system, including t, and
ii. plot a trace for each of the dependent variables as a function of time.
Plot each trace on a separate graph. To facilitate plotting, store the results of all time steps in the augmented state-array
a. each row represents the system at a different point in time
b. column 1 contains the time, and each other column contains the temporal history of a particular state variable
Store only the final result of each time step, not the predicted or non-converged corrected values. Title each plot ‘Var1’, ‘Var2’, etc. Try help plot and help title in the MATLAB command window to learn more about plotting. num2str will also be useful for creating the labels themselves.
Hints for your Function Script
Handling a System of Un-predetermined Size
Technical
Because you will not know in advance the order of the IVP your function will be asked to solve, some of the system parameters will need to be passed in as arrays, rather than as scalars. The step size and number of steps will still be scalars, but there will be an un-predetermined number of state variables, each of which will have an associated starting value and derivative expression. The starting value of each state variable is a scalar, so the collection of them can be stored in a normal array. On the other hand, your function script must be passed a separate function handle for the equation for the time derivative of each state variable. To store function handles, we must use a cell array. So then, you must be able to evaluate a function handle stored in a cell array. We did this in Lab #4, but I cover it again later in this document.
NOTE: Because your augmented state array will include time as the first value, the function stored in the nth index of the cell array is actually the derivative of the state variable in the (n+1)th index of the augmented state array.
Metaphysical
To figure out how to structure your code to deal with any size system, consult HW#9 and the notes from lab. In the HW, we performed RK3 on a 2nd order system. We can call the state variables x and v, and we can call their slopes (time derivatives) k and m, respectively. Feel free to write out and logically group the steps you took to solve the system for one timestep. Now, imagine we have 3 or 4 state variables each with their own slopes. Again, write out and logically group the steps you took to solve the system of equations. What changed about the process? Did the number of groups increase? Did the number of steps within particular groups increase? Now, we need to replace the RK4 algorithm steps with the ABM4 algorithm steps. Pay careful attention to the following differences:
a. the predictor and its modifier are performed once per time step, the corrector and its modifier are repeated until convergence each time step
b. the is no modifier on the predictor in the first time step
c. when performing the modifier steps, you use only non-modified values
d. when you check for convergence you compare only modified values
Function handles with unknown number of inputs
If you remember doing this for Modified Secant on a system of equations, then you may skip this section.
Up to now, you’ve probably only used function handles for equations that had a predetermined number of inputs. For this program, each derivative equation may be a function of the independent variable and any or all of the state variables. This is only a problem because you don’t know now (as you’re writing the function script) how many or which of the state variables will appear in each of the derivative equations. Fortunately, MATLAB allows us to put arrays into the equation function evaluation.
For example, if I define a function handle:
d1_by_dt = @(t,a) a(1) * a(3) / (2 + t);
when you ask MATLAB to evaluate the mathematical expression, MATLAB will expect to receive a scalar as the 1st argument, and an array of at least three terms as the 2nd argument. It will use the first and third terms in the array, along with the scalar, to evaluate the expression.
The augmented state array passed into the function already has t as the first value, so let’s just stick with that. Then our example equation becomes:
d1_by_dt = @(a) a(2) * a(4) / (2 + a(1));
You, of course, will have no prior knowledge of which state variables are used in each derivative expression. Therefore, for each derivative evaluation, you will need to submit an array containing the correct values of the dependent variable and all of the state variables, in the same order as the initial values in the passed-in augmented state array. When grading your code, it will be my responsibility to ensure that all of the derivative equations use the correct variables.
Function handles in cell arrays
The function handles of the derivative expressions of the several state variables will be passed to your function script in a cell array. The syntax for evaluating a function handle that is stored in a cell array is as follows:
value = array_name{n}(input1, input2, ... , inputQ)
• array_name is the name of the cell array in which the handles are stored
• n is the index into the cell array, in which is stored the expression for (d/dt)y n
• input1 thru inputQ are the inputs to the mathematical expression represented by the function handle – in our case that will simply be the augmented state array
Please note that those are braces around the index ‘n’ and parentheses around the arguments.
The ABM4 process
To calculate the predicted value of each state variable, you are going to perform very similar math:
n+1 ^0y k = n y k + h((55/24)g^k n - (59/24)g^k n-1 + (37/24)g^k n-2 - (3/8)g^k n-3)
where the k superscript on each g term matches the state variable number (the k subscript on each y term). Take advantage of how MATALB deals with vectors to simplify the process of calculating the predictor for all the state variable and each subsequent corrector for all the state variables. Create an array that holds the g m evaluations for all of the state variables. You will have 3 or 4 of these, one for each timestep. Then you can ...
temp_state = current_state + (h / 2) * slopes_array
Test your program
The spring-mass system from the Terminology section has been reproduced here.
Neglecting friction, the equations of motion of this system are:
ẍ1 = (-(k1+k2)x1 + k2x2)/m1
ẍ2 = (-(k2+k3)x2 + k2x1)/m2
where x1 and x2 are measured from the static equilibrium locations of the respective masses. To handle the 2nd order nature of the time derivatives, we must include additional state variables v1 and v2. If we arrange the state variables in the order x1, v1, x2, v2, the augmented state array becomes t, x1, v1, x2, v2, and the corresponding differential equations becomes:
dx1/dt = g1(a) = a(3)
dv1/dt = g2(a) = (-(k1+k2)a(2) + k2a(4))/m1
dx2/dt = g3(a) = a(5)
dv2/dt = g4(a) = (-(k2+k3)a(4) + k2a(2))/m2
Remember, a(1) is time, which does not appear in our equations of motion.
Create a main script (program) that performs the following tasks:
iii. define the system parameters (masses and spring stiffnesses)
iv. define the IVP functions above and store them in a cell array
v. set the initial condition of the augmented state array (time and all four state variables)
vi. call your RK4 function script
Set the system parameters to m1 = m2 = 1(kg) and k1 = k2 = k3 = 13.16(N/m). Set the initial
conditions to t = 0, x1(0) = 0.01(m), v1(0) = 0, x2(0) = -0.01(m), and v2(0) = 0. Call your RK4 function script with a time step of 0.001 seconds and 2000 time steps. Inspect the plots of x1 and x2. They should be mirrored sinusoidal functions with amplitudes of 0.01 and frequencies of 1Hz (2π rad/sec).
Analyze Your Custom Vibration System
You are going to customize the parameters of the spring mass system based upon your student ID number. Consider digits 4-5 as a two digit number X. Let digits 6-7 be a two digit number Y. If either X or Y are zero, pretend that they are 35.
Task #2: Apply Your Program
You will use your function to analyze a customized version of the vibration system depicted on the previous page. The system will be customized based on the last four digits of your student ID. Your goal will be to determine the second natural frequency and corresponding mode shape. For more details, refer to the Terminology section of this document.
Set the system parameters to m1 = 1(kg), m2 = (0.75-(X/200))(kg), k1 = k2 = 13.16(N/m), and k3 = (13.66+(Y/200))(N/m). Set the initial conditions to t = 0, x1(0) = -0.01(m), v1(0) = 0, and v2(0) = 0. Please note that the initial value of x1 is negative. Now, find the second natural frequency and second mode shape of your system by running your RK4 function multiple times, with different initial values for x2. I think the correct value should be > 0.01.
When you find the correct value of x2(0) each mass should demonstrate smooth sinusoidal motion. Inspect your table of state variables to determine the period of the oscillation. The period is the time between consecutive maximum displacements. The frequency in Hz is the inverse of the period. The mode shape is the vector [x1(0); x2(0)] scaled to have a Euclidean norm of unity (1).
Include in your Lab Report the following:
• the last four digits of your student ID number
• the values you used for X and Y
• the second natural frequency, in Hz, of your customized spring-mass system
• the normalized second mode shape of your customized spring-mass system
• plots of x1 and x2 as functions of time for two seconds
Provide the natural frequency and mode shape values to 5 significant figures.
Here is the RK4 chunk that is supposed to go on the top of the code for the function:
% In the code below:
%
% g is cell array containing the various dy/dt functions
%
% s_a is the augmented state array. It starts out as a row vector. It is
% passed in with the starting values of t and each state variable, in the
% same order as the function handles in the g cell array. It will
% eventually contain all of the values of t and the state variables over
% time.
%
% h is the step size
N = length(g);
slopes = zeros(4,N)
for iter = 1:2
state = s_a(iter,:);
for c = 1:N
slopes(1,c) = g{c}(state);
end
state = s_a(iter,:) + (h/2)*[1, slopes(1,:)];
for c = 1:N
slopes(2,c) = g{c}(state);
end
state = s_a(iter,:) + (h/2)*[1, slopes(2,:)];
for c = 1:N
slopes(3,c) = g{c}(state);
end
state = s_a(iter,:) + h*[1, slopes(3,:)];
for c = 1:N
slopes(4,c) = g{c}(state);
end
RK = (slopes(1,:) + 2*slopes(2,:) + 2*slopes(3,:) + slopes(4,:)) / 6;
s_a(iter+1,:) = s_a(iter,:) + h*[1, RK]
end
When this chunk is done, we should have three rows in the augmented state array, corresponding to our first three time points. It shouldn't be changed in any way while making the function script.
