Is there any one who knows how to apply machine learning algorithms to the spectrum data collected using ni usrp for ism band to use spectrum efficiently by link adaptation

Hi,
may i know any one working in cognitive radio research and applying machine learning techniques using the spectrum data collected from NI usrp kits

Can't edit my message anymore, so for the tldr crowd (too long didn't read), here is a shorter version:
The good:
E4200 worked fine for about 15 hours with great throughput and link quality (with one brief disconnect in the middle - online gaming software shows brief disconnects that otherwise go totally unnoticed).
The bad:
Wireless on the E4200 stopped broadcasting entirely (to a Windows 7 laptop with a 802.11n 2.4 GHZ USB adapter).
I had switched between two adapters that use the same chipset, same driver and in fact show up as a single device in device manager) without rebooting the router but it worked (fine) for an hour after I swapped the adapters.
Right before I rebooted it, I checked and the E4200 was not hot to the touch and wired internet was still working after the wireless radio stopped working.
A reboot of the router cured it.
The open question as to the root cause:
Now I want to know whether this wireless radio ceasing to broadcast (requires a reboot of the E4200) will happen daily?
I.e. I want to know whether it it really is overheating (then again why would only some have that problem needing to reboot daily while others have gone weeks with the E4200 without a single reboot being needed and without any problems occurring) or whether it had to do with changing the adapters back and forth without rebooting the router. Keep in mind that the router worked fine for an hour or so after I stopped swapping the adapters.
Extra question:
Will getting a Cisco AE1000 USB adapter perhaps help? (I know this is a loaded question and their is no easy / sure answer, but even a "maybe" or reasons why it might help at this point would be better than nothing.
Any similar experiences (with the router needing to be rebooted to get wireless radio back on) would be appreciated as it may help myself and others experiencing these types of issues.

    Everything is Sorted!
    The release of iTunes 11.0.2 and iOS 6.1.2 for my iPhone 4, seems to have sorted everything. I can now sync music, films and photos between my MacBook and my phone.
    I was dubious about blindly doing the updates but decided they couldn't really mess up any further functionality so I went for it and it's sorted now.

    Is there any way to know how much time swing client is on open state? My requirement is to show a message some time after the swing client open i.e., 4-5 hours.

    You could also consider using javax.swing.Timer and java.awt.event.ActionListener (or javax.swing.Action) which takes care of running the actionPerformed code on the EDT.

  • Is there any way to know how many copies of the same game I bought with GCU?

    I've bought Dying Light for ps4 probably twice or three times now.. Do return and rebuys count towards your limit of 3 copies of the same game bought with GCU? Or trade up offers? Or on a minimum of $5 deposit? Or does it have to be fully paid off to count?
    After purchasing the game today and having the employee adjust the price of the game for me since this physical weekly ad showed that Dying Light for GCU members is $31.99, I see on my receipt that there is no unlocked game discount. It just says sale price and price match discount. Now, the first employee tried to adjust it for me and applied my GCU which showed $39.99. When she adjusted it to $31.99, it went down to $25 so I guess GCU was applied even after adjusting it. She then called a manager and adjusted it to $31.99 and I got the game for $33+tax.
    So I'm guessing this purchase didn't count towards my limit since I didn't pay when GCU was applied and when it was adjusted, I don't see GCU game discount on receipt. Someone please confirm for me that this didn't count towards the limit. Thanks

    Hi SomethingNanika,
    First, thanks for being a Gamers Club Unlocked (GCU) member! It certainly sounds like you’re taking advantage of your benefits and I’m happy that you’re so consciously aware of the limitations of said benefits. I’m also happy to provide some details around the purchase limits and what does/doesn’t count towards those limits.
    When you purchase a game and pay for it fully, that counts as one towards your limit. If you return that game, that quantity of one is then removed from your limit. However, if you do a return and a rebuy, it basically counts as a wash, as you’re subtracting one and then adding it right back. Furthermore, simply placing a pre-order deposit doesn’t count towards your limit until the game is paid in full and the pre-order is fulfilled.
    Lastly, if your GCU benefits aren’t applied to a purchase, then you are correct in saying that would not count towards your limit of three titles. Also, here’s a refresher:
    “The limits for using your Unlocked membership will be three (3) copies of a new (i.e not pre-owned) video game software title per platform, per year. Collector's and Limited Editions count towards this title limit. Game of the Year editions, usually released much later and including additional content, do not count towards this limit. Game of the Year versions count as a separate title and have their own limit of three copies per platform, per year.”

  • Is there any one who can help me solve this?

    Hi.
    I'm taking AP Computer Scinece AB in high school now.
    I've been assigned many programs so far. But.. I can't figure them out.
    There are two programs I need your help. So..Please!!!!!! Help Me!!!!
    Please!! Enjoy helping me!
    <Program #1>
    It's divided into three small programs and I've figured out one of them, which was the easiest one..You will be able to see the programs if you click on the link below.
    (page1)
    http://iboard3.superboard.dreamwiz.com/board.cgi?db=90_darkoo&idx=2&page=1
    (page2)
    http://iboard3.superboard.dreamwiz.com/board.cgi?db=90_darkoo&idx=3&page=1
    <Program #2>
    http://iboard3.superboard.dreamwiz.com/board.cgi?db=90_darkoo&idx=4&page=1
    The way I figured out first part of program #1 was like this :
    public class ThreeX1
    public static void main ( string[] org )
    system.out.println ();
    int startValue = 21;
    int count = 0;
    while (startValue >1)
    count ++;
    if (startValue % 2 == 0)
    startValue = startValue/2;
    else
    startValue = 3*startValue +1;
    system.out.println ( count );
    ===================================================
    From there, for the second and third programs of program #1, I tried to figure it out by using 'for' statement instead of 'while', but I couldn't.
    So..Please help me out.. Thank you
    or you can e-mail me too. It would be great too.
    add. : [email protected]

    I probably shouldn't be doing your homework but here it is:
    public class ThreeX2{
         public static void main ( String[] org ){
              int startValue = 2;
              while(startValue<100){
                   System.out.print(startValue);
                   System.out.print("\t");
                   System.out.println(timesToGetToOne(startValue));
                   startValue++;
         private static int timesToGetToOne(int intForValue){
              int count = 0;
              while (intForValue!=1){
                   count ++;
                   if (intForValue % 2 == 0)
                        intForValue = intForValue/2;
                   else
                        intForValue = 3*intForValue +1;
              return count;
    public class ThreeX3{
         public static void main ( String[] input ){
              int maximumTries = 1000000;
              int numberOfitterations = 10;
              try{
                   numberOfitterations = new Integer(input[0]).intValue();
              }catch(Exception e){
              try{
                   maximumTries = new Integer(input[1]).intValue();
              }catch(Exception e){
              int startValue = 2;
              while(startValue<maximumTries){
                   if(timesToGetToOne(startValue)==numberOfitterations){
                        System.out.print("When startvalue is: ");
                        System.out.print(startValue);
                        System.out.print(" it will take exatly ");
                        System.out.print(timesToGetToOne(startValue));
                        System.out.println(" iterations to get to 1.");
                        // remove the next line and it will show all values that
                        // takes numberOfitterations amount of times to get to 1
                        break;
                   startValue++;
         private static int timesToGetToOne(int intForValue){
              int count = 0;
              while (intForValue!=1){
                   count ++;
                   if (intForValue % 2 == 0)
                        intForValue = intForValue/2;
                   else
                        intForValue = 3*intForValue +1;
              return count;
    }Problem 3 is diffucult, since the input is one date I assume that the current reading is for this date. I don't
    know the date of the previous reading so I cannot calculate if the consumption is between June through
    Ocober.
    your Main method shoud have 4 inputs date accountNumber currentReading previousReading
    Your main function would look like this:
         public static void main ( String[] input ){
              Calendar date=null;
              int accountNumber = 0;
              int currentReading = 0;
              try{
                   String[] s = input[0].split("/");
                   date = Calendar.getInstance();
                   date.set(Calendar.YEAR,new Integer(s[2]).intValue());
                   date.set(Calendar.MONTH,new Integer(s[0]).intValue()-1);
                   date.set(Calendar.DAY_OF_MONTH,new Integer(s[1]).intValue());
              }catch(Exception e){
                   System.out.println("cannot get date, please start this program the following way: ");
                   System.out.println("programName date(format mm/dd/yyyy) accountNumber currentReading previousReading");
              try{
                   accountNumber = new Integer(input[1]).intValue();
              }catch(Exception e){
                   System.out.println("cannot get account number, please start this program the following way: ");
                   System.out.println("programName date(format mm/dd/yyyy) accountNumber currentReading previousReading");
              try{
                   currentReading = new Integer(input[2]).intValue();
              }catch(Exception e){
                   System.out.println("cannot get current reading, please start this program the following way: ");
                   System.out.println("programName date(format mm/dd/yyyy) accountNumber currentReading previousReading");
              try{
                   previousReading = new Integer(input[3]).intValue();
              }catch(Exception e){
                   System.out.println("cannot get previous reading, please start this program the following way: ");
                   System.out.println("programName date(format mm/dd/yyyy) accountNumber currentReading previousReading");
    // check the date between june and oct:
    // (5>date.get(Calendar.MONTH))&&(9<date.get(Calendar.MONTH))

    If you use "capture://video", it will capture video from the default video capture device. When you create a player you need to specify a URI for the locating the media. More details are in the article I mentioned above.

    Well you would be first need to be using the ITUNES program. Not be on itunes the internet page. The program will usually be a music note icon on your desktop. IF YOU ARE GOING TO THE INTERNET = safari , internet explorer, firefox, etc ....your not using the program itunes. YOur surfing the web.
    with that said , always make sure your running the latest version of itunes. If on a mac  >in the upper left , next to the little Apple, click on the word itunes> check for updates.

  • Is there any one knows how to use labview 6.0 to make a "continue" function like the one in C language?

    I am using labview 6.0 and i like to know is there any one knows how to stop the current iteration in while loop or for loop and continue to do the next iteration,just like the "continue" statement in C or C++ language?

    Simple test here in LV6 confims that you can't do this. Not in a useful
    sense anyway. "Stop" doesn't stop execution simply of the current VI, it
    also kills all VIs above it. It would hence be difficult to argue that this
    approach is in any way similar to "continue".
    What version of Labview have you tested this on and can you post a
    demonstration?
