How to implement weather system

Greetings
I'm super new and I'm looking for a way to implement weather sensors if any one has any neat ideas on how to do this. So far I have a simple ciruit that connects a random gen funct. with an indicator but the problem with this is that my wave chart is chopy and bounces around a lot. Is there a way I can take my output and plug it back into my input for smoother results? I have a wire connection problem when I try doing this.
Thanks

Try a Feedback Node or a Shift Register.

  • How to implement Help System for an exit Web application

    I want to know detail steps to use OHW create a Help System for an exit ADF web application.
    I read a lot doc about Oracle Help.
    I down load the demo bundle and test it. It seems working. But it need to start separately. Also I do not know how to use it to build a help system for an exit ADF web application.
    Any body can help me to learn HOW with jdeveloper step by step.
    Thanks.

    Frank,
    Thanks for your reply.
    I checked the site that you mentioned.
    I try the sample “demo with bundle. The sample worked.
    But it needed to start separately with the application.
    I do not know how to build a help system with the existed web application developed with Jdeveloper (It has two projects: model and user-view-control. It is deployed on Oracle Application server).
    Could you help me step by step to build the help system?

  • How to implement for sap system use HADR

    hi expert ,
           i am a newbie to sap basis, we have a requirement that do HA for our sap using HADR,i want know if there are some good sulotion for my scenario。
       our scenaro is we have two window 2008 sever host,one host  has a sap system and we want the sap db2 database as a primary,and the other host also has a same the system which is restore from the previous sap system which we implement by system copy using database restore not migration。i want know as our secanrio could i achive SAP application HA by HADR,if we donu2018t have  HA  software  like MSCS。whether we must manual monitor the primary sap   when it stop because any issue like hardware failed and then manual start the other sap system in the other host?
      our two sap system have different sap profile beacause the hostname are different.
    our aim is when one of our host can't use we can immediate start the other sap system in the other host, the less the change the better the solution .
    is it possible?
    thanx very much,
    best regards.

    hi paul ,
        thanx for your information,i have already read the inforamtion about sg247363 once-over and SAMP。 but unfortunately we have a different situation,we only have two windows servers and must installed windows server 2008 OS because some reasons。we also don't have have other host to install sap。as this situation,how could we implement HA beacuse we also don't have shared disk。the window server are isolation。
    i  also read some pdf which download from sdn , in the book the HA is  implemneted as the sap application has a separate host and has two host for DB2 database using HADR,the HA is rely the cluster software 。in this situation the sap application also need HA to avoid single point failure。
        as the limited i have said above, is it possible to do HA by MSCS ,can any body tell me if the MSCS is free to install in OS windows 2008? if we can't use it  free,have any other solution?in the worst , we must manual monitor the application and when a sap application or database can't work ,we want to restart the other sap which in the other host,we need the database synchronization between two database which using HADR。is it possible ?if it do, whether there are some additional setup for sap application because the two sap application have different sap profile name(a sap is a system copy from the other by database restore)。
        any reply will be appreciated。

  • How to implement the security notes in Java System.

    Hi All,
    For the ABAP systems we use RSECNOTE to implement the security notes, but how do we do that in Java systems?
    Any reference or guidance will be of great help.
    Thanks,
    Akash.

    RSECNOTE is for ABAP only, and I dont think there is any equivalent for Java.
    For Java , security note will guide you on how to implement.
    It could be manual changes or via SDM or JSPM.

  • How should implement multi-thread in single-threaded Operating system using

    How should implement multi-thread in single-threaded Operating system using java?
    Java supports "Multi-threading".Is there is any way run the multiple threads (Implementing multi threading) using java in a Single-threaded Operating system (That is the operating system does not support for multi-threading).

    Previous questions from OP suggest they are using J2ME, so the question might be possible.
    806437 wrote:
    How should implement multi-thread in single-threaded Operating system using java?
    What is the actual question/problem?
    A java app doesn't do threads or not do threads. It uses classes. The VM does threads.
    So if you have a platform that does not have threads and you want to support the thread class then the VM, not a java app, must provide some pseudo mechanism, such as green threads, to support that.
    If your question is about java code and not the VM then you must build a task engine and insure that the tasks are of short enough duration that it is an effective use for your system.

    Hi Siddhehswar:
    I would suggest that you use the
    Ribbon. Because this is a flexible way for SharePoint. In my project experience, I always suggest my customers to use it. In the feature, if my customers have customization about permission then i can accomplish this as soon
    as possible. Simple put, I utilize this perfect mechanism to resolve our complex project requirement. Maybe we customize Upload/ Edit/ Modify/ Barcode/ Send mail etc... For example:
    We customize <Edit> Ribbon. As shown below.

  • How to implement reading data from a mat file on a cRIO?

    Hi all!
    I am not even sure, this is plausible, but I'd rather ask before i start complicating. So far, I have not found any helpful info about reading in data to a RT device from a file (kind of a simulation test - the data is simulated). 
    I have the MatLab plugin that allows the data storage read a MAT file, which has a number of colums representing different signals and lines representing the samples at a given time (based on the sample time - each sample time has it's own line of signal data). 
    I have no idea of how to implement this to cRIO.
    The idea is:
    I have some algorithms that run on the RIO controller in a timed loop. As the inputs to these algorithms, i would need to acces each of the columns values in the line, that corresponds to the sample time (kind of a time series - without the actual times written).
    I am fairly new to RT and LV development, so any help would be much appreciated.
    Thanks, 
    Luka
    Solved!
    Go to Solution.

    Hi Luka!
    MAT file support in LabVIEW is handled by DataPlugins. Here you can find the MATLAb plugin:
    http://zone.ni.com/devzone/cda/epd/p/id/4178
    And here you can find information on how to use DataPlugins to read or write files of a certain format:
    http://www.ni.com/white-paper/11951/en
    There is also an open-source project that addresses the problem, you can find it at
    http://matio-labview.sourceforge.net/
    Unfortunately, RT systems are not supported by DataPlugins, so fist you'll have to write a VI on the Host computer to convert your files to a usable format (I suggest TMDS for compactness and ease of use), and the work on the converted files in the cRIO VI. If you have other questions about DataPlugins or anything else, please get back to me.

  • How to implement multiple Value Helps within the same Application ??

    Dear Experts,
    I want to implement multiple value helps in the same view.For that I have declared exporting parameters of type 'wdy_key_value_table.' within the component controller for each of the value helps.While I do activate and test the application I get the following error :
    The following error text was processed in the system HE6 : A row with the same key already exists.
    The error occurred on the application server hsdnt24s11_HE6_00 and in the work process 4 .
    The termination type was: RABAX_STATE
    The ABAP call stack was:

    I dont know how to implement multiple value helps.Need your help on this.
    Regards,
    Mamai.

    Hi
    Hint is : A row with the same key already exists it means , It is assigning the same value/Key to row and you are calling it at WDDOINIT  so it giving error at the time of initialization .
    Better way to do the coding at some event in view OR if not possible than just execute the first value help in wddoinit later clear all the value before gettig the other Value help. Code it at WdDoModify View to get its run time behaviour.

  • How to design a system for a bank?

    The company I work for is about to design a system for a bank. This system will be used by office clerks to help their daily works. For example they can handle bank accounts, credit cards, credit products, loans, client data, stuffs like this. It's a kind of accountant system.
    As I don't want to reinvent the wheel I'm sure there are several solutions for this problem. Patterns, case studies, books, real life stories. I'm looking for them.
    Would you be so kind to recommend something I can use?

    I don't know how big a company you're talking about.
    I'd look into ERP systems like SAP,
    Oracle/PeopleSoft, Great Plains, etc.The task is to implement a system with which we can help the for of the office clerks. So we don't have to implement a whole accountancy system from the beginning to the end we just have to implement some kind of frontend and services for the frontend. These services will be used by the frontend and will be connected to the accountancy system of the company ( legacy app written in Cobol ).
    So I need some books, strategies, etc on how to implement, architect a tipical banking app. E.g. What does account (, banking products, loans ) really mean? What kind of tipical patterns should I use?
    I've browsed the web, of course, and I have found "Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions" for example but I'm not sure this is the thing I need. I've found Martin Fowler: Analysis patterns ( closer to what I need, so I've bought it already ). For example that one has a lots of patterns I should use ( Account, Transaction, Accounting Practice ).
    So I'm looking for something similar to the book "Analysis patterns" but with more with strategies and practical information on design and architectures as well.

  • How to retrieve the system used in an iview?

    hello,
    i'm currently having trouble retrieving the proper attribute of an iview to retrieve the system used by it.
    it seem like the strings identifying the system in the iview differ in some iviews.
    using either:
    myIView.getAttribute(IAttriView.PORTAL_SYSTEM)
    or
    myContext.getAttributes("").get("System").get().toString()
    produce errors.
    while get("System") sometimes provides the correct system alias the attribute is none existant for other iviews where the string would be "Systemalias".
    IAttriView.PORTAL_SYSTEM doesn't seem to work at all.
    i did implement fail safe code if the attribute isn't present, however i don't know how to retrieve the system attribute without doing a case switch or something similar for all the different strings, which i would prefer not to do.
    also, is there an easy way to retrieve all iviews which use a specific system without parsing the whole pcd and checking the attributes?

    Prerequisite : Create the System Alias for the systems used in the application.
    Use the below code to retrieve the system details:
            HashMap mapattr = new HashMap();
            HashMap map = new HashMap();
            IUser user = WDClientUser.getCurrentUser().getSAPUser();
            IPrincipal principal = (IPrincipal)user;
            ArrayList list = UMFactory.getSystemLandscapeWrappers();
            ISystemLandscapeWrapper systemLandscape = (ISystemLandscapeWrapper)list.get(0);
            //Portal System ALias name
            ISystemLandscapeObject landScapeObject = systemLandscape.getSystemByAlias("<system alias name>");
            IUserMappingData userMapping = (IUserMappingData) UMFactory.getUserMapping().getUserMappingData(landScapeObject,principal);
            userMapping.enrich(map);
            mappedUserId = map.get("user").toString(); // String "UserId"
            mappedPassword = map.get("mappedpassword").toString(); //String "Password" 
         catch(Exception e)
              e.printStackTrace();
              wdComponentAPI.getMessageManager().reportException("Exception during retrieving the User Details - " + e.getMessage(),true);

  • How to Implement HTTP Request Status Code Processing

    I actually have two questions. First, I wondering how to add multiple status code processing to an http request. Secondly, I was wondering how to go about using alternate http requests to different servers in case the primary server is down. What kind of parameter would the program use to determine that the server is unavailable and switch to another server??
    Currently, the program I've written calls an rdf server (http://www.rdfabout.com/sparql) using a sparql query,
    the server returns an xml string, the program parses it, and calculates numbers
    from the string. The program works, but the problem is that the server is down occasionally.
    When the server is down, we need to add calls to another server to
    increase reliability. So, the next task is to call this server:
    http://www.melissadata.com/lookups/ZipDemo2000.asp
    I need to do exactly the same things I did with the rdf server. The
    difference will be constructing a request and a bit different parsing of
    the response.
    current SPARQL query is defined as follows:
    PREFIX dc:  <http://purl.org/dc/elements/1.1/>
    PREFIX census: <http://www.rdfabout.com/rdf/schema/census/>
    PREFIX census1: <tag:govshare.info,2005:rdf/census/details/100pct/>
    DESCRIBE ?table WHERE {
    <http://www.rdfabout.com/rdf/usgov/geo/census/zcta/90292> census:details
    ?details .
    ?details census1:totalPopulation ?table .
    ?table dc:title "SEX BY AGE (P012001)" .
    }current HTTP Request is defined as follows:
    import java.net.*;
    import java.net.URL;
    import java.net.URLConnection;
    import java.io.*;
    import java.io.DataOutputStream;
    import java.io.BufferedReader;

    public class MyConnection
         static Scanner sc = new Scanner(System.in);//allows user to input zipcode
        public static void main(String[] args) throws Exception
             int zip;//zipcode is declared as integer format
            //User defines zip through input
            //proceed to put SPARQL query into string, which is then used to call the server
            String requestPart1 =
            "query=PREFIX+dc%3A++%3Chttp%3A%2F%2Fpurl.org%2Fdc%2Felements%2F1.1%2F%3E+%0D%0APREFIX+census%3A+%3Chttp%3A%2F%2Fwww.rdfabout.com%2Frdf%2Fschema%2Fcensus%2F%3E+%0D%0APREFIX+census1%3A+%3Ctag%3Agovshare.info%2C2005%3Ardf%2Fcensus%2Fdetails%2F100pct%2F%3E+%0D%0A%0D%0ADESCRIBE+%3Ftable+WHERE+%7B+%0D%0A+%3Chttp%3A%2F%2Fwww.rdfabout.com%2Frdf%2Fusgov%2Fgeo%2Fcensus%2Fzcta%2F";

            String response = "";
            URL url = new URL("http://www.rdfabout.com/sparql");//designates server to connect to
            URLConnection conn = url.openConnection();//opens connection to server
            // Set connection parameters.
            conn.setDoInput (true);
            conn.setDoOutput (true);
            conn.setUseCaches (false);
            // Make server believe we are form data…
            conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
            DataOutputStream out = new DataOutputStream (conn.getOutputStream ());
            // Write out the bytes of the content string to the stream.
            out.writeBytes(requestPart1 + requestPart2 + requestPart3);
            out.flush ();
            out.close ();
            // Read response from the input stream.
            BufferedReader in = new BufferedReader (new InputStreamReader(conn.getInputStream ()));
            String temp;
            while ((temp = in.readLine()) != null)
                 response += temp + "\n";
            temp = null;
            in.close ();
            //parsing stuff is taken care of after here
    }What remains now is to:
    1) add status code processing: notify if the server is not available, ect.
    2) add ability to connect to additional server if primary server is down.
    I'm thinking an if/else statement, which I've tried a few different ways,
    but I don't quite know how to implement that...Also trying to add the
    status code processing/error handling, but I'm not sure how to do that
    for multiple/different errors, such as 404, 503, 504, ect.. try/catch statements?
    So yeah, just been scratching my head on this trying to figure out how to work it..
    If you can help me out on this, I've been going nuts trying to figure this out...

    I think your issue comes form the fact that you are not casting URLConnection to HttpURLConnection.
    Doing the cast would allow you to use getResponseCode() - among other methods - and test for a response different than 200.
