kandi X-RAY | chassis Summary
Chassis is a collection of new classes and enhancements to existing projects for building maintainable applications. I choose the name "chassis" because I'm a car guy. A chassis is a car's foundation. Every car has key components: there is an engine, transmission, differential, suspension, electrical system, and a bunch of other things. They fit together on the chassis in a certain way, there are guidelines but no one is going to stop you from building a custom front suspension on a typical chassis. And that's the point. The chassis is there to build on. It does not make decisions for you. There are also kit cars and longblock engines. Kit cars come with some components and rely on you to assemble them. Longblocks are halfway complete engines. The engine block and valve train are predecided. You must decide which fuel delivery and exhaust system to use. Then you mount it in the chassis. In all things there is a line between prepackaged DIY and turn-key solutions. This project is a combination of a chassis and long block. Some things have been predecided and others are left to you. In that sense this project is a utility belt. All the components are there, you just need to figure out how to put them together. This project chooses an ideal gem stack for building web applications and enhancements to existing projects. It's just a enough structure to build an application. It is the chassis you build your application on. Here's an example I put together.

QUESTION
I have been struggling to find the solution for below requirement
Input string is Sum(Spec("any text1" : "any text2"),spec("any text3" : "any text4")) I want to match the string spec("any text1" : "any text2") and spec("any text3" : "any text4"))
pattern which I tried is Spec\(([^)]*)\)
This pattern works for above input , but if any of the any text1 ,any text2, any text3 and any text4 contains parenthesis then it fails to match
ex input Sum(Spec("any text1 with (bracket)" : "any text2"),spec("any text3" : "any text4"))
It is also possible that text can contain the quotation marks as well "chassis \"4\"".

QUESTION
I'm trying to recreate simple SQL query in DAX. The output Query needs to work in Power BI Report Builder and I have been trying all day reading all sorts of PowerBI / DAX online resources to rewrite this.
A little bit about the data:
- The data is structured in three tables, CustomCar, Engine and Chassis.
- Basically "CarId" is the key that connects all three tables.
- Let's assume all tables have more than 20 columns. so only a few of the columns are needed in the final output.
- All three tables (CustomCar, Chassis and Engine) have an
IsActiveproperty (the relationship between Engine/Chassis to CustomCar is MANY-TO-ONE. Because an engine might blow up and they change it therefore somehow we want to track which Engine is on the car today and what engine was on it last year, however, at any time, there is only one active engine for each car.. The same goes for Chassis) - Both Engine and Chassis have 'Manufacturer' and 'Model' columns so in the output query they need to be identified from each other.
- I am not trying to sum any sort of sales number, just a list of cars with their current configuration.
Any help is appreciated.
...ANSWER
Answered 2021-May-11 at 21:58I have found a work around for this. I added the query when adding the data pipeline in Power BI dashboard and will use the values from the query as is.

I want to send the data as well as image to my database with Alamofire, by appending the data to the request body. Now I've successfully inserted all the data, but not the image (the image is not inserted to the database). The image comes from .photoLibrary or .camera and then convert it as bitmap string data before send the image to the server. How to insert converted bitmap image to the database with alamofire?

QUESTION
Im reading a sine wave from a wave generator with a Labview FPGA code, when the frequency is around 1Hz, this is what I read (as expected)
However when I increase the frequency, this happens.
I see that the ticking speed does not change, so I think it would be solved if it accelerated just as much as I needed to match my sine wave. Also, I passed the data through a FIFO and to a .txt file that I then plotted and I cant see the sine wave either, so its not only a problem of the chart display.
How can I control this?
PS. I checked my hardware and it supports 50 MS/s, so it should not be a problem to nicely read a 10 Hz sine wave. In particular, Im using the NI 5751 ADC, FPGA 7951R, PXI 1071 chassis.
...ANSWER
Answered 2021-Apr-28 at 21:15You are seeing Aliasing of the data being presented in your waveform.
In this case it is due to a significant under-sample rate of the data that is being passed up to your waveform. As @Kerghan mentioned, the primary issue here appears to be that your data rate for grabbing is not correctly related for the data sampling you are trying to see. I would suggest that if you are trying to see a 10 Hz waveform you should be using a minimum display rate of 20 Hz ( 50000 uS ).
As an aside, you have fallen into a traditional LabVIEW trap for developers coming from text based languages. I would recommend that you remove the Flat Sequence Structure from the code, as this is enforcing the following logic:
- Wait X uS of time
- THEN read data from the AI If the time taken to read the data and write to the DMA is non-zero, your timing will be off by just the slightest amount and it will be very hard to tell why.
QUESTION
Such as in the 'racecar' example, could I set a lower and upper limit for the 'mass' design_parameter and then optimise the vehicle mass while solving the optimal control problem?
I see that there is an "opt" argument for phase.add_design_parameter() but when I run the problem with opt=True the value stays static. Do I need another layer to the solver that optimises this value?
This feature would be useful for allocating budgets to design decisions (e.g. purchasing a lighter chassis), and tuning parameters such as gear ratio.
...ANSWER
Answered 2021-Apr-06 at 13:54It's absolutely possible, and in fact that is the intent of the opt flag on design parameters.
Just to make sure things are working as expected, when you have a design parameter with opt=True, make sure it shows up as one of the optimizer's design variables by invoking list_problem_vars on the problem instance after run_model. The documentation for list_problem_vars is here.
If it shows up as a design variable but the optimizer is refusing to change it, it could be that it sees no sensitivity wrt that variable. This could be due to
- incorrectly defined derivatives in the model (wrong partials)
- poor scaling (the sensitivity of the objective/constraints wrt the design parameter may be miniscule in the optimizer's units
- sometimes by nature of the problem, a certain input has little to no impact on the result (this is probably the least likely here).
Things you can try:
- run problem.check_totals (make sure to call problem.run_model first) and see if any of the total derivatives appear to be incorrect.
- run problem.driver.scaling_report and verify that the values are not negligible in the units in which the optimizer sees them. If they're really small at the starting point, then it may be appropriate to scale the design parameter smaller (set ref to a smaller number like 0.01) so that a small change from the optimizer's perspective results in a larger change within the model.
If things don't appear to be working after trying this and I'll work with you to figure this out.
QUESTION
I am looking for a way to display the numeric value 0 in a dropdown list that also includes placeholder text when the cell is empty. Currently, if 0 is selected the placeholder text shows through. I'm hoping for a built-in option and I'd like to avoid casting the number to string and back if I can (that would tear up my current validation scheme). The following example is modified from the HandsOnTable dropdown docs. The 'Chassis Color' column contains the issue.
jsfiddle: https://jsfiddle.net/y3pL0vjq/
snippet:
...ANSWER
Answered 2021-Mar-10 at 17:53The best way I found to handle this dropdown list of numbers is to omit the "type" attribute and specify the editor and validator as 'autocomplete. Then make a custom renderer to merge the NumericRenderer functionality with the autocomplete dropdown list.
To finalize the similar look and feel of the native dropdown function, you then add "strict: true" and "filter: false", as explained in the dropdown docs.
Internally, cell {type: "dropdown"} is equivalent to cell {type: "autocomplete", strict: true, filter: false}. Dropdown Docs

I am trying to edit array values using jquery. here is what I did.
From a modal, everytime I click the "Add item" button it will push values to an array and just append the data to a table
...ANSWER
Answered 2020-Nov-27 at 06:30You can give data-* to your edit button i.e : data-id="row1"..etc then on click of this button get the data-id value and use filter to filter the JSON Array already created and get only data where row == data-id.
Now , once you got the array values put this values inside the input-box of modal using .val("yourfromarray"). Then, onclick of save button get the value from input box and loop through your JSON Array and update value of array with new values.Lastly add these updated value inside trs.
