kandi X-RAY | Quantities Summary

Quantities is a Swift library typically used in Mobile, iOS applications. Quantities has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a Swift module for working with physical quantities with units, like velocities, angles, masses, etc. It is heavily inspired by the new Measurement and Unit types in Foundation. I wanted to see if I could build a purely Swift version of these that I could use for deployment to older OS versions (Measurement in Foundation currently requires macOS 10.12 and iOS 10) and to experiment with extensions to the support provided using Swift's type system. In particular, I wanted to see if I could make it even easier to create and work with these numbers, as well as experiment with composite unit types and complex calculations. I've changed the names to Quantity for the base numerical type and DimensionalUnit for the unit types to avoid conflicts with Foundation. The number of units I support is a little limited now, only because I haven't taken the time to enter them all in with conversion factors.

            you are almost there.. you just need to use the same logic to join to the product master table. However, since you need the total of quantity, you need to group by the other columns you select (but not aggregate).

            The query will be something like this :

            How do I take gradients of MultibodyPlant computations w.r.t. mass, center-of-mass, inertia, etc.?
            Asked 2021-Jun-09 at 12:41

            I see the current chapter of Underactuated: System Identification and the corresponding notebook, and it currently does it through symbolics.

            I'd like to try out stuff like system identification using forward-mode automatic differentiation ("autodiff" via AutoDiffXd, etc.), just to check things like scalability, get a better feel for symbolics and autodiff options in Drake, etc.

            As a first steps towards system identification with autodiff, how do I take gradients of MultibodyPlant quantities (e.g. generalized forces, forward dynamics, etc.) with respect to inertial parameters (say mass)?

            ANSWER

            Answered 2021-Jun-09 at 12:41

            Drake's formulation of MultibodyPlant, in conjunction with the Drake Systems framework, can allow you to take derivatives (via autodiff) with respect to inertial parameters by using the parameter accessors of RigidBody on the given plant's Context.

            There's a couple ways to do this. If it is ok for the user to enter a comma-separated list, then eval is very helpful. This will automatically convert the values to floats/integers.

            How to distribute stock quantity from a single cell to different aging brackets based on the the aging brackets quantities?
            Asked 2021-Jun-07 at 14:38

            We have a table with item codes and current stock quantity and quantities in aging brackets whenever they were received (1-90, 91-120, etc) as follows:

            I need to distribute the STOCK_AS_ON_DATE quantity in the age brackets until no balance quantity is left.

            Example:

            Item A's STOCK_AS_ON_DATE is 40377, in A1TO90 column we can see that 4000 quantities were received, in A91TO120, 4000 quantities were received, in A121TO270, 13000 quantities were received, we want to distribute the STOCK_AS_ON_DATE quantity in such a way in the other aging fields until the total of all the aging fields equals STOCK_AS_ON_DATE. In this item's case, when we reach column A631TO720, 1377 quantity balance is left out of the 40377. If any aging bracket value is 0, we have to leave it as it is and move forward.

            A brute-force approach might be to use least() to decide whether to use the column quantity or the remainder from adding up all the columns to the left; with greatest() to stop any negative values. Something like:

            Local Storage in JavaScript deleting all items instead of just one

            I have been working on a vanilla JS project (no JQuery) and I am implementing local storage to save data on refresh. My below code is deleting all the items in the local storage array instead of the particular item I have set to be removed. Any help appreciated!

            ANSWER

            localStorage only accepts one argument, which is the key of the item you want to remove: https://developer.mozilla.org/en-US/docs/Web/API/Storage/removeItem

            What you need to do instead is mutate the local items and quantities arrays (remove the appropriate items) that you parsed from localStorage, then do localStorage.setItem('items', items) and localStorage.setItem('quantities', quantities).

            The problem is resolved when blit=False, though it may slow down your animation.

            Just quoting from a previous answer:

            "Possible solutions are:

            Put the title inside the axes.

            Don't use blitting"

            Need to change variable name in a for loop everytime in Java Android Studio
            Asked 2021-Jun-01 at 18:30

            I am a beginner level programmer and I am again here to take everybody's help and solve my problem. Actually I don't have an error this time but I need to do something which I am not able to, The thing is that I want to use a for loop 3 times and everytime I have a condition to check if my Quantity1 = 0 or not, again if my Quantity2 is = 0 or not and same for the third time. I can also repeat the code 3 times but I need to do this is because, I am uploading my data to a realtime database. And I am uploading my SelectedDate1 if Quantity1 != 0 and same for the three times, but to read them I have to know that how many Quantities and SelectedDates are uploaded and for that I have created a variable OrderQuantity. But the problem is if the user has selected the 1st date and the 3rd date and not the 2nd one as its quantity is 0, so when it is uploaded it shows OrderQuantity=2and the selectedDate1 comes under 1 but the 3rd date comes under 2nd node with name 3, but it should come with the name of variable+i, I hope you understand my question. And if not, please comment and I'll provide you an english video for what I want. Hoping your help as soon as possible.-

            I think there is no use of main_activity.xml as it will make my question very big.

            Edit: go object-oriented

            Edit: since my first two suggestions didn’t work for you, I am suggesting using some abstraction. Declare a class to hold a spinner and its related data, and iterate a list of such objects. Your list can hold a variable number of objects so there will be a variable number of spinners. Caveat: I don’t know Android UI programming, so may be missing a detail or two there. And I still have not compiled my code myself.
