rotor | based framework for rust for doing I/O in simple

For a project I have, I control a BLDC motor with it's own current controller.

To design a controller for the motor I fitted some time traces to the flowing function:

to capture the dynamics of the entire system, namely, motor, current controller/driver and load.

J is the rotor inertia, [kg*m^2]

r a dampening constant (linear friction)

tau is a torque constant [Nm/A]

u[t] a current input

der(der(phi)) is the angular acceleration

der(phi) the angular velocity

The fitted values represent the entire system more than good enough for a 'continuous' approximation of the motor, the load and the current controller/driver of the motor. With the control scheme, I give a signal u(t) in Amps, and I expect a torque and an angular velocity as an output. At the time I only needed the angular velocity, but I digress, this method worked fantastically, but was fitted and designed in mathematica.

I would like to build a much larger, and significantly more complex robotic system within modelica (Systemmodeler specifcally, however, modelica library 3.2.x), however I am having some issues.

My first attempt was:

However, when simulating this with another outside load (an external model), I have a lot of issues, from some those more experienced than I, I am told this form of modelling is 'one way' and not the 'modelica method' but more simulink in form.

Namely, it should be bi-directional, not just numerical outputs, in order to correctly react with the multibody external model, this will connect to.

My second attempt was:

Which when connecting to my larger multibody model, it does indeed work more like it's expected to, there is a reaction from this model, when external torques/loads are applied. However, when simulating this model to see how it fairs compared to the pure block model, they arn't the same by any means. I had to spend a lot of time trying to fit the inertia and friction data to get similar results.

SO my question is, what is the best method, to turn pure block models (mathematical ones) or atleast,my pure block model, into a more realistic model or atleast, the connecting outputs into more realistic, or I guess 'acasual' ones.

I would prefer not to use my second attempt, since I can't trust the values I had to adjust compared to the block to actually be correct, since they arn't fitted values to real world data, compared to my first model.

Program description : Lapindrome is defined as a string which when split in the middle, gives two halves having the same characters and same frequency of each character. If there are odd number of characters in the string, we ignore the middle character and check for lapindrome. For example gaga is a lapindrome, since the two halves ga and ga have the same characters with same frequency. Also, abccab, rotor and xyzxy are a few examples of lapindromes. Note that abbaab is NOT a lapindrome. The two halves contain the same characters but their frequencies do not match. Your task is simple. Given a string, you need to tell if it is a lapindrome.

My code :

I have a view controller with this layout (note that yellow and table views are siblings):

I want the yellow view to act as a container, so I'm doing this in viewDidLoad:

I'm a "noob" Java student who is trying to complete the next problem, it's about finding palindromes. I've tried to do it but i can't get the solution! As I said I'm "noob", I only use the "standard" public class, I don't know how to explain it, but I'm still learning, so I don't know even how the functions work, you can make it complex, but not too complex xD. Here it is, thank you people:

A palindrome is a word that is typed the same way from left to right and also from right to left, for example: Y, EE, ALA, ANNA, ROTOR or AAAAAA

Ask a word to the user and identify if it is a palindrome or not, and also show how many diferent palindromes the word has inside.

I/O examples:

I have a docstring in the beginning of every module describing its usage and functionality. Here I also want to add the most relevant parameters - like settings in a parameter file or via command line arguments. It's no classical function parameters since the module might be called as stand-alone as well (via if __name__ == '__main__' capture). But since the ordinary parameter formatting of Sphinx is neat I want to just re-use it.

However, Sphinx seems to handle the "Parameter" section differently when in a module compared to when in a function.

This is how they are formatted differently:

You see the difference. In functions the keyword "Parameters" is added and then we have a nice bullet list. In modules no title is created, no list, the type is not set in braces but on an additional line etc.

Docstring format is the same (numpydoc):

1. Icing of the engine and the leading edges of the intake duct can occur during flight through clouds containing supercooled water droplets or during ground operation in freezing fog. Protection against ice formation may be required since icing of these regions can considerably restrict the airflow through the engine, causing a loss in performance and possible malfunction of the engine. Additionally, damage may result from ice breaking away and being ingested into the engine or hitting the acoustic material lining the intake duct. 147 2. An ice protection system must effectively prevent ice formation within the operational requirements of the particular aircraft. The system must be reliable, easy to maintain, present no excessive weight penalty and cause no serious loss in engine performance when in operation. 3. Analyses are carried out to determine whether ice protection is required and, if so, the heat input required to limit ice build up to acceptable levels. Fig. 13-1 illustrates the areas of a turbo-fan engine typically considered for ice protection. 4. There are two basic systems of ice protection; turbo-jet engines generally use a hot air supply (fig. 13-2), and turbo-propeller engines use electrical power or a combination of electrical power and hot Ice protection Fig. 13-1 Areas t picall considered for ice protection. Fig. 13- Hot air ice protection. 148 149 Ice protection air. Protection may be supplemented by the circulation of hot oil around the air intake as shown in fig. 13-3. The hot air system is generally used to prevent the formation of ice and is known as an anti- icing system. The electrical power system is used to break up ice that has formed on surfaces and is known as a de-icing system. HOT AIR SYSTEM 5. The hot air system provides surface heating of the engine and/or powerplant where ice is likely to form. The protection of rotor blades is rarely necessary, because any ice accretions are dispersed by centrifugal action. If stators are fitted upstream of the first rotating compressor stage these may require 149 Ice protection protection. If the nose cone rotates it may not need anti-icing if its shape, construction and rotational characteristics are such that likely icing is acceptable. 6. The hot air for the anti-icing system is usually taken from the high pressure compressor stages. It is ducted through pressure regulating valves, to the parts requiring anti-icing. Spent air from the nose cowl anti-icing system may be exhausted into the compressor intake or vented overboard.

How can I use regex to get 1. , 2. ... I tried using this but to no avail ^\d..*(?=\d.), it gives me everything

I'm trying to do a 301 redirect using the IIS URL rewrite module. I've googled, looked at videos and put in different settings but it does nothing...meaning, the link I set up the redirect on still just works as before. I don't even get an error.

Here are my settings:

• Requested URL: Matches the pattern
• Using: Regular expressions << I've tried 'exact match' as well...same result, didn't work.
• Pattern: Turf/ProductView.cfm?P=151
• Ignore Case: checked
• Action type: redirect
• Redirect URL: https://www.weathermatic.com/products/6000-pro-rotors/{R:0}
• Redirect Type: permanent 301

I've also tried using a Redirect URL that was within the same domain as the link I'm trying to redirect...again, nothing happens, the link still just works as before and no errors either.

Any help is so much appreciated.

I am trying to do a risk matrix using Python that integrate severity and probability, I already tried using heatmaps, and it is maybe the closest kind of graph I have found so far, but I think it does not represent the basic structure of a risk matrix. The next image shows the kind of matrix graph I want. I would appreciate any recommendation: library, link...whatever to be able to graph a risk matrix.

This is the data I am trying to locate inside the risk matrix:
