pedal | computer music composer , I found the transition | Machine Learning library

So I am simulating plane flight. The plane flies certain distance (pathx and pathy variables) and then the simulation stops, when certain pathx and pathy values are reached. The solver is trying to minimize the fuel consumption (m.Maximize(mass*tf*final), by maximizing the mass value. The solver controls the accelerator pedal position (Tcontr).

Right now the termination condition is defined like this:

For X axis:

So I am simulating plane flight. The plane flies certain distance (path variable) and then the simulation stops. The solver is trying to minimize the fuel consumption (m.Maximize(mass*tf*final), by maximizing the mass value. The solver controls the accelerator pedal position (Tcontr). I need it to try and keep Velocity value V above certain threshold(for example >=100). What kind of equation I need to add for that to happen?

My code:

I have a 3 deep array. Currently, the code will isolate a record based on one field ($profcode) and show the heading. Eventually, I am going to build a table showing the information from all the other fields. The code so far is using in_array and a function that accepts $profcode. I am unsure if (and how) I need to use array_keys() to do the next part when I retrieve the "Skills" field. I tried:

I need to solve 1D plane flight optimal control problem. I have a plane that is 1000m high. I need it to travel 1000m forward along x-axis while minimizing fuel consumption. And when it achieves x=1000 I need program to stop.

My objective function looks like this: min J => -mass(tf). (By maximizing mass, the consumed fuel gets minimized). Optimizer controls the accelerator pedal.

The problem is subject to the following constraints: dx/dt = V; dV/dt = (Throttle - Drag)/mass; dm/dt = -Throttle * fuelflow.

I have developed a Gekko / Python script as follows. However, the optimization script does not achieve a solution, raising:

I am trying to calculate the non zero minimum of a column within groups using dplyr. I have seen a few similar questions around, however, none seem to work. Let's see an example with iris. I would like to create a new column :min_length, with the minimum pedal length higher than 1 for each species (I did not use 0 for this example to fit the dataset). I tried:

Cyclists are recording pedalling power over time and analyse a curve1 derived from this that plots for every given time interval the amount of power at least produced: for 20 continuous minutes, you maintained 248W or more. I'd like to compute this in R starting from small time intervals dt and corresponding power pwr:

I'm doing some fundamental exercises while learning from a class. One of the exercises uses def function and i thought that the example they provide is rather unrealistic so i wanted to bring it all together.

I'm new to Stack Overflow. I'm trying to have a simple e-mail form on my website, so I've copied one but can't get it to work. The "Send" button just doesn't seem to do anything. I am not a programmer and know very little about code

A friend told me it's as if the PHP isn't recognized.

After following some suggestions I now have the "Send" button working, but I get the "Could not send mail" popup message.

The PHP file gives a "Syntax error, unexpected $EOF" message for line 52 (exit;) Not sure if this is what's blocking the PHP from running...

I am working on a side project that involves multiple modals on one page. I followed the W3 schools modal tutorial, but it doesn't perform exactly how I want. Note: I am extremely new with JS.

How do I serve up a similar but different image with a different SRC (https://storage.googleapis.com/img.triggermail.io/hammacher/1839_HS_History.jpg) after clicking on the modal, rather than showing the same image zoomed in?

Here is a link to my codepen project: https://codepen.io/jkramer25/project/editor/AooxzJ

Thanks.
