How To Install Oracle Bussiness Intelligence Virtual Machine

1. Firstly install "7 zip" program. 
2. Then download virtual machine files from this link (download) . After downloading parts select all parts and right click. Then select "7 zip" menu and select "extract here" section.
3.  Kopy Image key file "VB Image Key File" same location to extracted parts.
4.  Install "Virtual box" program. Double click "Sampleapp_v107_GA" file and click import button.
5. Depending on your network configuration and the option selected in the virtual box settings, you may need to configure the hosts file to point it to the correct IP address. Services will not start properly if the IPaddress is not correct. Please follow the steps below to configure the hosts file: Get the IP address of the image – For this, open a terminal window on the running image, and type the command /sbin/ifconfig. Note down the IP address under the heading “inet addr” (e.g.: inet addr:192.168.56.101) Navigate to folder /etc/hosts and edit the file so that the entry demo.us.oracle.com points to the correct IP address of your machine Save the file and proceed to starting service
6.  Sequence for service starting scripts

It is critical that the environment is brought up by starting scripts in the proper sequence as described below :

For information, the 11gR2 database is automatically started when the VM image boots up. There is no need to manually start a service to bring it up.

6.1 Start OID Services

On the desktop, double click on StartupScripts folder and select “1-startOID.sh” and choose „Run in Terminal‟ option. (/home/oracle/Desktop/StartupScripts). Wait until the terminal screens disappears, allow 5 seconds after that before you move on to starting the next services.

Note : if you start OID by using aliases, make sure you run both startOIDopmn and startOID aliases sequentially

6.2 Start WebLogic Server

On the desktop, double click on StartupScripts folder and select “2-startWLS.sh” and choose „Run in Terminal‟ option. (/home/oracle/Desktop/StartupScripts)

Wait for the message that shows "Server started in RUNNING mode". This indicates that WLS is up

Leave this terminal window open

6.3 Start OBIEE Services On the desktop, double click on StartupScripts folder and select “3-startBI.sh” and choose „Run in Terminal‟ option. (/home/oracle/Desktop/StartupScripts) Wait for the command to complete successfully. The terminal screen will disappear automatically. To check on status of services, you can open a terminal screen and simply type :

„statusOPMN‟. This will call an alias and will report the information as per the image on the right.

6.4 Start Essbase Services

NOTE : if you are running the virtual box with less than 3GB of allocated RAM, you should NOT start the essbase services as the performance of the image will suffer dramatically. Most of Samples will work outside of essbase examples, even without Essbase service up.

On the desktop, double click on StartupScripts folder and select “4-startESSB.sh” and choose „Run in Terminal‟ option. (/home/oracle/Desktop/StartupScripts)

Once finished, you can run /epm/Middleware/user_projects/epmsystem1/bin/opmnctl status to see the status.

Note : if you Start Essbase by using aliases, make sure you run both startESSB and startAPS aliases sequentially

Periodic Noise Reduction by Frequency Domain Filtering

This blog explain how to minimize periodic noise by frequency domain filtering using matlab. There ara some filtering  methods. Picture1 has some periodic noise,firstly we convert this picture to frequency domain in matlab.

Picture1

KOD:This code show picture in frequency domain with logaritmic improvement(Picture 2)

>> r2=rgb2gray(imread('n3.jpg'));

>> fr2=fft2(r2);

>>imshow(log(1+abs(fftshift(fr2))),[]);

Picture: 2

 We can use "Data Cursor" of matlab figure viewer to find noise's location. (Picture: Points Of Noise)

   



Picture Points Of Noise

1. First Method 

1.1 Mask 1

KOD: There are six point on the picture,its my be noise, First method clearing this noise with mutiply this area(six point) to zero. Picture size is 206x245. Our mask is ones(206,245),but change only six point area to zero like Picture 3 . We can create this points with  using "Points Of Noise"  picture.  We use +-1 pixel neighboardless arround the this points.

>> m=ones(206,245);

m(59:1:61,122:1:124)=0;

m(79:1:81,73:1:75)=0;

m(124:1:126,73:1:75)=0;

m(146:1:148,122:1:124)=0;

m(81:1:83,171:1:173)=0;

m(125:1:127,172:1:174)=0;

imshow(m);





Picture 3



KOD:If we multiply this mask and frequency domain,Picture 4 is formed.

>> imshow(log(1+abs( fftshift(fr2).*m)),[]);

Picture 4

KOD: ifft2 function is converting frequeny domain to begining domain.Firs method of filtering finished. There are some improvement on the Picture 5

imshow(log(1+abs(ifft2( fftshift(fr2).*m))),[]);



Picture 5

 1.2 Mask 2

KOD:If our rectangle of six point is larger then Picture 3,There may be some better  improvement then Picture 5. We use +-2 pixel neighboardless arround the this points.

>> m(58:1:62,121:1:125)=0;

>> m(78:1:82,72:1:76)=0;

>> m(123:1:127,72:1:76)=0;

>> m(145:1:149,121:1:125)=0;

>> m(80:1:84,170:1:174)=0;

>> m(124:1:128,171:1:175)=0;

>> imshow(log(1+abs(fftshift(fr2).*m)),[]);



Picture 6



KOD: Converting Picture 6 to begining domain

>> imshow(log(1+abs(ifft2( fftshift(fr2).*m))),[]);



Picture 7

2. Second Method 

2.1 Introduction of circular function 

KOD: Frequency domain have circular spread. If the mask is circular ,there maybe better improvement than Picture 7 and Picture 5.Firstly I want to explain how to draw circle on matris of our mask.



Picture 8

The center of the circle is (a,b) point. The function of circle has shown very sipmly (x-a)^2+(y-b)^2=r^2  on Picture 8.If we square both right and left of equal,there are sqrt((x-a)^2+(y-b)^2)=r function.


Example:

r=2.5 and a=5 and b=5 

>> [X Y] = meshgrid(1:10);

>> C = sqrt((X-5).^2+(Y-5).^2)<=2.5

We want to draw six point of noise with circle and this circle's variables are zeros for clearing noise
C = sqrt((X-5).^2+(Y-5).^2)>=2.5

We do not want to filled circle
>> C = sqrt((X-5).^2+(Y-5).^2)>=2.5|sqrt((X-5).^2+(Y-5).^2)<=1;

2.2 Creating Mask

 

Now we can draw our real filter. We need to point center of the circle.

Center=(123,104)
a=123,b=104
r=104-60=148-104=44
formula=>sqrt((x-a)^2+(y-b)^2)=r =>sqrt((x-123)^2+(y-104)^2)=44
We want to thick circle and we must find an epsilon to do this. If the epsion is numeric number of two our formula change like this: sqrt((x-123)^2+(y-104)^2)=(44+2) | sqrt((x-123)^2+(y-104)^2)=(44-2)
KOD

[X,Y]=meshgrid(1:245,1:206)

>> C = sqrt((X-123).^2+(Y-104).^2)>=46|sqrt((X-123).^2+(Y-104).^2)<=42;

>> imshow(C);



Picture



 mesh(C*5+1);

2.3 Multiplying mask and frequensy domain of picture 

imshow(log(1+abs( fftshift(fr2).*C)),[]);

There are four noise whice not drowed. We must onother circle to draw this four noise. We can use Picture: Point of Noise

C = sqrt((X-123).^2+(Y-104).^2)>=56|sqrt((X-123).^2+(Y-104).^2)<=53;

 imshow(log(1+abs( fftshift(fr2).*C)),[]);

2.4 Concatenate the circles

 

We must to concatenete this circles

>> C1 = sqrt((X-123).^2+(Y-104).^2)>=46|sqrt((X-123).^2+(Y-104).^2)<=42;

>> C2 = sqrt((X-123).^2+(Y-104).^2)>=56|sqrt((X-123).^2+(Y-104).^2)<=53;

>> CS=(C1+C2)>1;

>> mesh(CS*10+1);

>> imshow(log(1+abs( fftshift(fr2).*CS)),[]);

2.5 Result of masks

2.5.1 Result of C1 mask

imshow(log(1+abs(ifft2( fftshift(fr2).*C1))),[]);

2.5.2 Result of C2 mask

imshow(log(1+abs(ifft2( fftshift(fr2).*C2))),[]);

2.5.3 Result of CS mask

imshow(log(1+abs(ifft2( fftshift(fr2).*CS))),[]);




 



Custom Ribbon in Sharepoint 2010

This blog explain how to create your own ribbon for sharepoint.

1. Open your project and right click your solution and select "add" tab and then select "Sharepoint mapped folder..." tab .when you select this tab the window opens.

2. Create "Scripts" and "Icons" sub folder in "Layouts" folder.Add Icon to Icons Folder(16x16 and 32x32). Add script to scripts folder.

function showAll() {

    var ctx = SP.ClientContext.get_current();
    var ItemIds = "";
    var listId = SP.ListOperation.Selection.getSelectedList();
    var selectedItems = SP.ListOperation.Selection.getSelectedItems(ctx);

    for (var i = 0; i < selectedItems.length; i++) {

        ItemIds += selectedItems[i].id + ",";
    }

    var pageUrl = SP.Utilities.Utility.getLayoutsPageUrl(

        '/_layouts/ReportHandler.ashx?id=' + ItemIds + '&listid=' + listId);
    var options = SP.UI.$create_DialogOptions();
    options.width = 520;
    options.height = 380;
    options.url = pageUrl;
    options.dialogReturnValueCallback = Function.createDelegate(null, OnDialogClose);
    SP.UI.ModalDialog.showModalDialog(options);
}

function enableAll() {

    var ctx = SP.ClientContext.get_current();
    return SP.ListOperation.Selection.getSelectedItems(ctx).length > 1;
}

function showSingleControlReport() {

    debugger;
    var ctx = SP.ClientContext.get_current();
    var web = ctx.get_web();
    var ItemIds = "";
    var listId = SP.ListOperation.Selection.getSelectedList();
    var selectedItem = SP.ListOperation.Selection.getSelectedItems(ctx)[0];

    var pageUrl = '/_layouts/ReportHandler.ashx?id=';

    var options = SP.UI.$create_DialogOptions();

    options.width = 520;
    options.height = 380;
    options.url = pageUrl + selectedItem.id + '&listid=' + listId+'&rType=itk';
    options.dialogReturnValueCallback = Function.createDelegate(null, OnDialogClose);
     window.location.href = options.url;
}

function enableSingleControlReport() {

    var ctx = SP.ClientContext.get_current();
    var selectedItems = SP.ListOperation.Selection.getSelectedItems(ctx);
    return selectedItems.length == 1;
}

function OnDialogClose(result, target) {

    if (result == SP.UI.DialogResult.OK) {
        location.reload(true);
    }
}

3.Right click your solution and select "new item" tab and then select "Empty Element" on sharepoint tab

4. Set your Element.xml file in "Empy Element" control like this...

</Elements>

5.Your custom ribbon is ready to use.You only set your ReportHandler.ashx (may be aspx) page and doing some thing in this page (or handler). You can get selected item id's in your page querystring and do something to listitems where selected in list. You can get selected item id with key of "id" from query string and you can get list id with key of "listid" from query string of page.

Changing Executable Path Of Windows Services

Open regedit (start=>run=>"regedit" command and enter)  

Go this directory 

HKEY_LOCAL_MACHINE=>SYSTEM=>CurrentControlSet(May be Control Set1 or Control Set1 )=> Services =>YourServiceName=> ImagePath

HTML Filtering

This blog explain how to filter your html. You may want to replace some word with another or you may delete some world in html.You have to configure your webconfig file and write your module in the <modules> tab .This code handle client  request and change it when posting this request to client.

Code

/// <summary>
    /// Html içeriğinin kelime filtrelemsini sağlayan modül
    /// </summary>
    public class WordFilterModule : IHttpModule
    {

        /// </summary>
        /// <param name="app"></param>
        public void Init(HttpApplication app)
        {
            app.ReleaseRequestState += new EventHandler(InstallResponseFilter);
        }

        /// <summary>
        /// Filtrenin yüklenmesini sağlayan metod

        /// <param name="e"></param>
        private void InstallResponseFilter(object sender, EventArgs e)
        {
            HttpResponse response = HttpContext.Current.Response;
            HttpRequest request = HttpContext.Current.Request;
            //if (GeneralFunction.UsersResponces.ContainsKey(HttpContext.Current.User.Identity.Name))
            //{
            //    GeneralFunction.UsersResponces[HttpContext.Current.User.Identity.Name] = HttpContext.Current;
            //}
            //else
            //{
            //    GeneralFunction.UsersResponces.Add(HttpContext.Current.User.Identity.Name, HttpContext.Current);
            //}

            if (response.ContentType == "text/html")
            {
                //Debug.Write("in InstallResponseFilter()");
                response.Filter = new ModifyHtmlContentFilter(response.Filter);
            }
        }

Frekans Bölgesi ve Fourier Dönüşümü

Frekans Bölgesi ve Fourier Dönüşümü

Şekilleri sin ve cos fonksiyonları kullanarak ifade etmeye Fourier Dönüşümü denir. Doğadaki nesne şekilleri sin ve cos fonksiyonlarının toplamı şeklinde ifade edilebilir.

 Şekil 1 deki resme forurier dönüşümü uygulandığında Şekil 2 deki resim oluşur.Bu resmin görünebilmesi için bir takım değişiklikler yapılmıştır. Aksi taktirde ortadaki kare o kadar açık renktedir ki aradaki tonlama farkı bunu ifade edemez.

Sekil 1

Kod

rk=imread('r_kare.bmp');

f=fft2(rgb2gray(rk));

 imshow(fftshift(log(1+abs(f))),[]);

Şekil2

Frekans uzayını  yükselen ve alçalan değerler ile çarpma

Eğer frekans uzayını yükselen değerler ile çarparsak renk geçişleri daha belirgin olur , bir başka değişle kenarları çizmiş oluruz.Eğer alçalan değer ile çarparsak yüksek renk geçişleri düşer yani kenarlar belirginsizleşir ve resim matlaşır. Burada anlatılacak kodlarda sadece maske(“m”) değişkeni değişmektedir.

Kod

r=rgb2gray(imread('r_robot.bmp'));

f=fft2(r);

m=fft2([-1 -1 -1;-1 8 -1;-1 -1 -1],128,128);

g=m.*f;

t=ifft2(g);

imshow(abs(t),[]);
