            Modelica smoothOrder of cubic polynomial
            Asked 2021-May-26 at 09:16

            After reading the resources linked below, I have a question about Modelica annotation smoothOrder.

            For a cubic polynomial the derivatives are:

            1. derivative: quadratic function
            2. derivative: linear function
            3. derivative: constant value
            4. derivative and higher: zero

            What is the number to put into the annotation smoothOrder in this case? Is it 3, or 4, or is it 99? There are no discontinuities.

            ...

            ANSWER

            Answered 2021-May-26 at 09:16

            If it is a pure polynomial (not something like a piece-wise polynomial), the smoothOrder is actually infinite. The reason is - as you state in the question - that after some higher-order derivative all further derivatives will be zero. Therefore it does not get discontinuous.

            As a result, the smoothOrder can be set to any high value. To finde a good value, lets consider the usage of the annotation: smoothOrder is used to determine how often a variable/equation can be differentiated. Differentiation of equations can be necessary due to the index reduction. How often a model needs to be differentiated is determined by the model's index (for which there are slightly different definitions). Generally the index describes, how often an equation needs to be differentiated to result in solvable equations. The index is usually not higher than three, for electrical applications it is usually not higher than one. Therefore, often 99 is often chosen as the index will not get higher than this...

            Substitute an interface for another one
            Asked 2020-Nov-29 at 22:47

            Recently, I stumbled upon an interesting article regarding the organization of Go code.

            I was highly interested in the third approach: 'Independent Packages'. It's said packages should NOT depend on each other, but defines their own interface to interact with other packages.

            Now, I face a problem with the approach.

            I'm building a CLI applications that's able to execute various commands, one after each other. It's important that these commands can share data.

            This will not work because the function signatures don't match. You can do:

            • Make Context a shared interface, so every package can use it. This does not necessarily introduce dependencies between packages using it.
            • Use context.Context, and expect to see the key in there. This is essentially the same as #1 but using a known predefined type
            • Use interface{} instead of context, and use type assertion to convert it to the local context type.

            Correct way to set up ActiveMQ network of brokers
            Asked 2020-Oct-08 at 23:49

            As explained in this question, we have a network of brokers consisting of three brokers on different servers. The network connectors are configured as follows:

            ANSWER

            Answered 2020-Oct-08 at 23:49

            These settings should get you that 'prefer local' behavior you want:

            decreaseNetworkConsumerPriority="true" suppressDuplicateQueueSubscriptions="true"

            Also, add messagTTL = 4 and consumerTTL = 1. This allows messages to hop around n + 1 times. (Where n is the number of brokers in your cluster). Also, consumerTTL = 1 means brokers will only see consumers from their immediate peer, and not see over multiple hops.

            In your use case, drop the networkTTL setting-- messageTTl and consumerTTL replace it and give you more control over message hops and consumer awareness.

            how to do multi-loop PID Tuning in the Modelica model?
            Asked 2020-May-04 at 07:01

            Tuning the PID parameter is crucial in the control system development, here is an example of how to do this for just one PID controller. https://www.claytex.com/tech-blog/tuning-pid-gains-dymola-modelling/

            But if there are multiple PID controllers in the Modelica model, IS there a standard procedure of tuning the parameters?

            Is there a Modelica library for multiple PID controller tuning?

            ...

            ANSWER

            Answered 2020-May-04 at 07:01

            Is there a standard procedure to tuning parameters: Likely not, as this a pretty big area in engineering. It strongly depends on the type of system you need to control, although you limited to PID already, for which a set of tuning methods exist.

            In the Dymola Manual 2 there is a section about tuning parameters using the Design library based on the example Design.Optimization.Examples.ControllerDesign_F14. The tutorial related is given in section "First optimization setup". It uses optimization and should be rather generally applicable. Also the LinearSystems2 library can be of great help, as it provides tools for controller design, e.g. a state-space representation of a model (after linearization).

            Regarding your specific problem, it is a bit difficult to judge from your screenshot, but assuming it is cascaded control, this should help. In case the controlled variables influence each other they should be decoupled, as e.g. shown here. If non of the before is the case and there are no strong limitations expected in the actuators manual tuning seems feasible.

            BTW: Modelica is especially well suited for complex control problems as it can use the plant model to do inverse control. But this seems to be a bit over-engineered for your application.

            Bash script behaves unexpected / Strange
            Asked 2019-May-27 at 19:25

            First I want to apologize for being an absolute noob at programming, writing scripts, etc. I'm running a FreeNAS Server and a Raspberry Pi which I'd like to include a sh-Script which should check if 8 clients (IP addresses) are online. If yes they should stop but if all IP's are offline, it should perform another task / script.

            Here's my problem: On the internet (src: https://www.tech-blogger.net/freenas-automatisch-bei-nicht-benutzung-abschalten/) I found a script which checks specific IP's and if they're offline it should shutdown automatically. When I ping those addresses I get 100% package lost which indicates that they are offline. But the script echos me that at least one client is offline. Because I'm not THAT dumb I assume that it has something to do with my code. Does anyone know what goes wrong with my Script?:

            I am not 100 % sure if I get your Problem right. But I think you should try to replace || with && in your if statement.

            || = or && = and

            Thus it will only go into the shutdown parts, when all Clients are off.

            Web App created from ARM template - can't disconnect deployment
            Asked 2019-Mar-06 at 19:55

            I created a web app, app plan and resource group using a template adapted from that generated on the Azure portal, and the powershell script that is also from the azure portal.

            It failed to link to my bitbucket repo or install an extension but was otherwise successful.

            However, if I try to disconnect my deployment in the Deployment Center to connect to Bitbucket manually, it just shows the three dots busy animation but never finishes. See screenshot attached:

            Answered 2019-Mar-06 at 19:55

            You would have to follow below steps to disconnect the deployment in this case.

            1. Go to https://resources.azure.com/ i.e., go to your newly created App service resource in Azure portal and click on 'Resource explorer' tile.
            2. Now in Resource Explorer, go to config -> web.
            3. Make sure you are in "Read/Write" mode rather than in "Read only" mode.
            4. Click "Edit" to update the "web" JSON file.
            5. Now change "scmType" key's value to "None".
            6. Click "PUT".

            Just a note on failed part is, AFAIK your template failed to link bitbucket repo because it could not find source control token for your bitbucket repo.

            Hope this helps!! Cheers!!

            As specified in the Slick doc, groupBy currently doesn't support executing a query with nested values of type Query:

            The intermediate query (i.e. the query ended with groupBy() without an aggregate function) contains nested values of type Query. These would turn into nested collections when executing the query, which is not supported at the moment. Therefore it is necessary to flatten the nested queries immediately by aggregating their values (or individual columns)

            In other words, your Slick groupBy query must be coupled with an aggregate function equivalent to SQL's count(), sum(), etc. For example, the following query which is equivalent to select count(*) ... group by ... having count(*) > 1 would work:

            Copy and update record expressions — the one, which allows you to write { rec with prop = val } — is a convenient shortcut for creation of new record with a few changes from existing record instance.

            I may be wrong, for sure, but this syntax is allowed for record types only, while you've declared a Match class with custom constructor, which is not a record.

            So you may want to use a record instead.
