Trigonometrial equation with several solutions on HP50g

Hello!

I am trying to solve the following equation:

1.5 * Xf + 2 * cos (Xf) = 2.158.

But it's a little more complicated than that. Using the command ADDRESS, I get:

XF = 0.5247...

But this equation comes to solve some integration that goes from Xo = 0.848 this XF I find in the above equation. So, Xf should be greater than 0.848.

Is there a way to fix this? I tried LINSOLVE, but it won't allow me to use X > 0.848 as a conditionant. The ZEROS command does not work either.

Thank you very much!

Have you tried to see if any graphic alternatives?  No doubt outside the ABS > 3.

  • Interfacing with several unknown USB devices; all producing NMEA strings

    Hi all

    Question about the peripheral USB interface and their associated drivers.

    I have the obligation to build an application that interacts with the USB devices that produce NMEA strings. I have the library to parse NMEA strings, but I fight with interfacing with several unknown USB devices. When deploying applications, I know not all possible USB devices to use.

    Is it possible to produce one driver who will accept any USB device strings?

    Or, more likely, is there a way to get the LV to recognize a connected USB device and automatically find / install the driver like windows does and is it possible to do in a deployed application?

    I had a trawl of the forums, but I've not found anything that specific.

    Thanks, I really appreciate the help.

    About the VI "set up the serial port", my problem is that the choice of COM port is in a separate menu (not directly related to the VI) and it allows all possible COM ports to be selected. That can be addressed.

    I am not expecting an all-in-one solution but asked the question in case it was possible.

    What I realized, is that for my specific condition to read strings from a USB device. It is likely to be sent over a serial connection. LV can handle this well and easily assuming the device has the installed driver / settings are available.

    LV (and indeed any other program) will not work without a device driver / settings. In this case, parameters set must be found (error) / a USB RAW driver would need to be developed. Devices requirng a RAW USB driver would need a serious review to continue due to the time and effort required. All this effort is work inherited from the AIDS to navigation

    I appreciate any help and I think I got the answer I was looking for! Thank you very much

  • Closure of a state machine in queue event with several parallel loops

    I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)

    I look forward to any comments on my as well code, if someone is willing to offer it.

    My program needs:

    If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.

    Architectural details:

    The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.

    During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".

    In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".

    HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.

    I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.

    I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.

    Thank you!

    First of all, close the notifier outside loops with your queues.  Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

  • Slide with several digital poster Down filter event Bug button?

    A key event filter on a slide with several digital screens down does not work as expected when not waived. If you for example tab of this slide with two digital screens digital display, the cursor remains on his position, rather than get KeyFocus to the next control. Same behavior at fault if you want to move the cursor on the left/right keyboard, nothing happens. Anyone an idea why?

    A simulation of that VI is attached. All other controls, a Slide with a digital display or a standard digital control, the key Down event filter behaves as expected... I tested in versions 8.5.1 LV (attachment), LV2012SP1 and LV2013.

    A teammate now found a solution or workaround. We do not know if this is the way it should be, if yes, then it's a bit hidden, but it works!

    It seems that the cursor needs to know on what digital display the FocusObj is when you use the event notifier KeyDown. Then, when to get the reference of the digital display active and the wiring of this reference to the terminal FocusObj filter event everything works as expected, numbers of tabs, typed, cursor etc and have to filter and notify events structure to the event.

    A vi and a printscreen are attached.

    The question is probably due to the specialty of slides and the class NumericWithScale in general, as its digital displays are a little under References and during the implementation of the features of event KeyDown for the class NumericWithScale filter, LV simply does not know on which side of the main action control part must be executed.

    Or someone has a better solution and explanation?

  • Equation with dynamic variable

    Is it possible to use an equation with 2 or more variables, and to make one of these variables as output without changing the equation?

    Take the formula below, example:

    R=x/(0.28706/0.46153+x)*(101.325/P)

    As usual, by inserting the values of x and P, then the value of R will receive a response.

    But if only the value of R and x can be inserted, how the value of P to decide without changing the equation.

    The equation is used multiple times in the same VI. One to generate a part of a graph (Mollier diagram) and the other must be used to find the value of the point of intersection.

    I hope that my question is understandable.

    Thanks in advance

    sikat-

    You simply set the two formulas:

    R (x, P)

    P (x, R)

    and select the one according to the inputs and outcomes.

    N R should be reserved for cases where there is no analytical solution.

  • I'm stuck with several GB of music files on my phone and I can't get down them!

    The other day I tried to install an application on my phone, but I didn't have enough memory.  My phone is full of music via iTunes synchronisation dock. So I connected it to my computer to try to make some more room. But there is a problem.

    (1) Apple does not play nice with Palm. Synchronization is no longer permissible or possible. I can't use iTunes to manage/delete music.

    (2) in USB Mode, there is no way to access/view the library. It's just not there.

    I tried Palm support, and they confirmed that the USB Mode is not working. I guess that the library is located in a hidden folder or directory. They suggested that I downgrade my iTunes. Goal that is unacceptable to me because one) it forces me to break the license Apple, b) it is not taken in charge, and c) if there is still a remote chance it will mess up my iTunes library, I won't.

    I'm ready to get off at Palm headquarters and throw my phone to their building.

    Can someone tell me how to delete my library without hacking iTunes?

    I thought about it. Support, put this in your KB. Everyone who was sync via iTunes on a Mac is currently STUCK with several GB of music on their phone that they cannot manage or remove, which makes the Palm Pre a lot less useful than announced.

    USB mode is a waste of time for people on a Mac. These hidden files are never going to be visible, and the library cannot be removed. The solution: go through a PC. Anywhere, any PC will do. Connect your phone to the PC, go to the USB drive Mode and show hidden files, then delete them from there.

  • Unable to create cache with several tables group

    Hello

    I need to create a group of cache with several tables, which are referential to the other.

    There are 2 related tables and table 1 child...
    While trying this thing, it gives me an error:

    8222: multiple parent tables found

    It is not possible to use several tables of root in a single cache group? Is there another way to use it?

    Script, I used is:

    create a cache group asynchronous writethrough TEST. CG1
    of the TEST. ROOT1)
    KEY PRIMARY ID VARCHAR2 (8 BYTES),
    NAME VARCHAR2 (50 BYTE),
    DESCRIPTION VARCHAR2 (255 BYTE),
    POLICYTYPEID VARCHAR2 (7-BYTE)),

    TEST. ROOT2)
    PARAMTYPEID VARCHAR2 (5 BYTES) PRIMARY KEY,
    PARAMETERUSAGE VARCHAR2 (1 BYTE),
    NAME VARCHAR2 (25 BYTE),
    DESCRIPTION VARCHAR2 (255 BYTE)),

    TEST. CHILD1)
    PARAMDETAILID NUMBER (20) PRIMARY KEY,.
    ID VARCHAR2 (8 BYTE),
    PARAMETERUSAGE VARCHAR2 (1 BYTE),
    DISPLAYVALUE VARCHAR2 (255 BYTE),
    OPERATORID VARCHAR2 (5 BYTE),
    VENDORID NUMBER (20).
    FOREIGN KEY REFERENCES TEST. ROOT1 (ID),
    TEST KEY (PARAMETERUSAGE) REFERENCES STRANGERS. ROOT2 (PARAMETERUSAGE));

    You can't have multiple root within a group of cache tables. The requirements for tables in the group a cache are very strict; There must be only one top-level (root table) table and there may possibly be several children tables. Tables of the child should be linked through foreign keys to the root table or a child table above in the hierarchy.

    The solution for your case is among the tables of root and the other root table in a separate cache group and the child table in a cache group. If you do this, you must take care of a few things:

    1. you cannot define foreign keys between the tables of groups of different cache in TimesTen (keys may exist in Oracle) so the application must enforce referential integrity itself for these cases.

    2. If you load data in a cache group (using LOAD the GROUP CACHE or "load we demand") and Timesten will not automatically load the corresponding data in the other group of cache (since he doesn't know the relationship). The application must load the data into the other group of cache explicitly.

    There is no problem with transactional consistency when changes are pushed to Oracle. TimesTen maintains and reinforces the coherence transactional regardless of how the tables are arranged in groups cache correctly.

  • Shortcut for the new window with several tabs

    Is it possible to have a shortcut on the desktop to launch a new window with several tabs? For example - home page is set to "www.google.com", but the shortcut opens new window with tabs "www.cnn.com" and "www.youtube.com".

    Then far,.../firefox.exe-nouveau-fenetre followed by the two URL in quotes will open two new windows. Entry - new-window "www.cnn.com" - new-tab 'www.youtube.com' will open two new windows if no instance of firefox is open, but if another window is already open, youtube will add a tab to the already open window, rather than the new window with cnn.com

  • FIRST HP: Solving a system of linear equations with a parameter

    Hello

    I know how to solve a system of linear equations by using a setting by hand but I don't know how to set up in the calculator.

    Can someone please help me solve the system of linear equations below with a 'p' on the first HP Calculator next parameter?

    2 x + 8z = 26

    4 x-4y-14z = - 38

    8 x - 4y + 2z = 14

    The answer to the above equations is:

    x = 13 - 4, =(45-15p)/2, z = p y p

    Thank you

    Arthur

    Hello

    What you're trying to solve is not really a system of equation with a parameter, but you try to solve a set of 2 equations with 2 variables (x and y).

    The case solve command can do for you.

    According to the CASE, type:

    Solve ([(2*x+8*z) = 26,(4*x-4*y-14*z) = - 38,(8*x-4*y+2*z) = 14], [x, y])

    Come in

    and the calculator will return

    {[-4 * z + 13, 15/2 * z + 45/2]}

    which is what you want.

  • HP 6500 scan high resolution works well with the solution Center HP; but is solid black w/imgage software for editing

    I got an OfficeJet 6500.

    I can scan the image using the HP solutions, at the same high resolution Center, and the image will scan very well.

    I think there is a setting for the Windows operating system that needs to be adjusted. I know because I had this same problem once before.

    I found the solution to my problem. but my computer crashed and I had to reinstall the full Windows operating system. I lost the changes I had made. It was in January 2011.

    I don't remember when I had the answer to my problem but I thought that I asked the question in the HP forum (it would have been some time in late 2010) and then someone answered with the solution to my problem. But I can't find the post I did then.

    Hello JimTrail

    After watching this on the web, it seems that you is maybe to something. From what I found, GIMP uses a lot of resources, especially true for larger images. He isn't able to handle the scanning of an image as large as 4800dpi without additional RAM or virtual memory to compensate for the RAM.

    My suggestion would be to increase the size to the recommended or higher. Out of curiosity how much physical RAM have you? Microsoft recommends that virtual memory for no more than 3 times the amount of RAM installed. See article: change the size of virtual memory.

    You can also see the article below on the Tile Cache GIMP.org.

    I set features three following user using "Define."

    UF1 takes a single patameter;

    Œuvres F1.  F2 is the EVAL of F1 version and it works too.  User functions only seem to work fine.

    F3, a function of two user settings, produces a graph of NaN.

    F4 is the EVAL of F3 version.  Note that 'B 'is not replaced by 1'.  Also produces a NaN chart.

    F5 produces a graph of NaN.

    F6 is EVAL of F5.  The 'X' is not replaced (even with the ' B' above), and even if it looks like 'X * X', it also produces a graph of NaN.
