Generate random oscillating waves

Hello,
I'm stuck on something that may be pretty simple to do... I'm trying to get waves that look like this: http://www.scientificamerican.com/media/inline/000C600B-7F33-1C71-9EB7809EC588F2D7_arch1.gif to show up on a waveform graph.
The thing is I need to set an upper and lower limit and then have them go up and down randomly. I've looked in the simulate signal and I can't find anything that'll make it oscillate randomly between the two limits that I set.
Thank you for your time.
-Tom

I agree with Lynn - pure sine waves will give you a good indication of your code is working properly and not corrupting the signal in any way - it's much tougher to see problems with what is essentially random signals. You can also insert slow square waves (like 0.1 Hz) to see if your code correctly passes both DC and fast edges properly.

How do you generate random data info using json and spry?

I have a mobile applicaton that uses spry datasets that dynamically populate a jquery mobile listview by using a json file. Everything is operating as it should.
However, I would like to understand how to pull random objects from the json file to have them displayed on a different page.
My json file is standard and not complicated. It has several levels. Each is represented as below:
                              { "Level1":
                                                            {"imageurl":"images/_myimage.png",
                                                            "someData":"S,A,P,R",
                                                            "levelLongDesc":"further description",
                                                            "name": "John Doe",
                                                            "page": "referencepage",
                                                            "description":"The description of the image"
{"imageurl":"images/_myimage.png",
"someData":"S,A,P,R",
"levelLongDesc":"further description",
"name": "John Doe",
"page": "referencepage",
"description":"The description of the image"
Json file Level1 has about 70 objects
What I would like to do is randomly load one of the Level1 object arrays into the page when the user selects a Level 1 radio button that is on the screen. I know how to create the page, radio buttons and basics, but just don't know how to pull in the random data.
I've found one code sample on this site that speaks to spry and xml, but I haven't been able to apply it in any way that works for me with the json file:
http://forums.adobe.com/message/662551
I've also googled. There isn't much on spry datasets with json and generating random info. There was a little bit on sorting, but that didn't help either.
Does anyone have a good example/tutorial of how to use the random function with spry/json?
TIA
-Rachel

I've done similar things before. A few thoughts for you:
1. I'm assuming you're doing a buffered period or frequency measurement on the incoming encoder pulses, right? First key point is that you'll have data that is spaced equally in position, but not equally in time. If you are looking for a time-based FFT such that increasing speed will shift your spectrum, you're going to need to go through an interpolation process to resample your data as though equally-spaced in in time.
2. Your 149 pulse per rev encoder may be a significant source of error unless its 149 pulses are placed with extreme accuracy. Any error in pulse placement violates your underlying assumption of data that is equally-spaced in position. It'll be very helpful to send your data through a software lowpass filter to attenuate those artifacts.
3. I am not sure what you mean by "decompose the buffered data (array) into a single datastream." You'll get an array of periods / frequencies from the call to DAQmx Read. If you want to use it in a LabVIEW waveform datatype, you'll first need to do the resampling to create equally-spaced-in-time data. The LabVIEW waveform datatype (and all the analysis functions like FFT that use it) depend on receiving data with a fixed constant time interval between samples.

Generate random User Alias - Entity adapter

Hi,
I am a newbie. Can anyone please help me in telling steps for creating an Entity Adapter which generate a random User Alias.
TIA.
Got few threads that tell about pre-populate adapter, none for entity adapter.

Hi,
Follow the below steps to create new entity adapter in OIM
To add the new created event handler to OIM server, perform the following steps:
1. Write a java code to perform the needed operation ("Generate random user alias" in your case).
2. Copy the file to OIM_HOME\xellerate\EventHandlers
3. Open Design Console and navigate to: Development Tools -> Business Rule Definition -> Event Handler Manager
4. Create a new Event Handler and specify:
Event Handler Name: +<give the class name of your code>+
Package: +<give the package name of your code>+
Pre-Insert: Checked (for this scenario)
5. Save the event handler
6. Navigate to Development Tools -> Business Rule Definition -> Data Object Manager
7. Search for "Users" and add the event handler to the Pre-Insert list.
8. Save.

NS

Need An Algorithm That Generates Random Numbers

Hi, I understand that there is a built-in random number generator. But, I need an algorithm that generator random numbers. Is there one available? Thanks.

Hi, is the "Seminumerical Algorithms" a book?What
the numbers 3141592621 and 907633385 stand for?The first is PI without a decimal... the second I
don't know, it may as well be randomly picked.As far as I know the numbers aren't randomly picked. You want the distribution to be good, and the length of the serie should also be long. Some numbers causes the cycle to be short, or the distribution to be bad. I think there are articles that lists 'good' numbers.

I am unable to control my iPad 2. It is generating random letters when typing and when I try to delete it generates more letters unless I go slowly! Any advice?

I am unable to control my iPad 2. When typing and deleting it generates random letters! Any advice

Start with this and see how it goes. Quit all apps completely and reboot the iPad.
Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

No, that defeats the purpose of a public forum. And no one is going to e-mail you (other than someone trying to sell V1AGRA).

Help needed with generating a sine wave with NI-5640R card

Hi there,
I have created a simple programe using the 5640R card, and i am attaching the programe to this question. Using a "sine generation" function/block i am generating a sine wave and outputting to one of the o/p ports and then i am connecting that o/p port to one of the i/p ports using a cable. Then i am plotting what ever i have recieved through the i/p port (this has to be same as what is generated using "sine generator" ). The graph shows that i am not receiving aything from the i/p port, but when i plot the o/p of the "sine generator", i see that the sine generator is generating the sine wave. Please refer to the attached figure and please tell me what mistake i have made in this simple programe.
Thanks,
Sandeep.

Hi sandeep
This small segment of code will not work on the NI PCI-5640R. This module does not support running the FPGA Vis directly. A Host VI must be run that calls to the FPGA Vis.
I suggest that you look at the ni5640R Analog Input and Output example that is installed by the NI PCI-5640R software.

PS: Make sure that you are using the NI PCI-5640R software version 1.1.

Generate random number and letter in a text field ...

Hi All,
I having a bit trouble when trying to generate random number and letter in application express in a text field. Say I have a licence form and when user wants to create a licence, it will provide a random licence number in the licence number field but it has to be unique. the number should be something like HQ2345. I was trying to set the following sql in default value for that text field but it is not working -
select DBMS_RANDOM.STRING('',2) || trunc(DBMS_RANDOM.VALUE(1000,9999))
from dual;
any suggesion !!!!
thanks

Put this as default value for your text-item
DBMS_RANDOM.STRING('',2) || trunc(DBMS_RANDOM.VALUE(1000,9999))
with type PL/SQL Expression. It have tested it and it works fine.

Generating Random Dollar values

I need a section of code that will generate a random number (double) between 10000.00 and 10000000.00 for a tax program. What is the best way to do this?

Math.random()*10000000.00 + 10000.00;:)) I thing you have neglected something... this generates random numbers between 10000.00 and 10010000.00...
A correct thing would look like:
double low = 10000;
double high = 10000000;
Math.random()*(high-low)+low;

Generating random number within size of map problem (why me!!) ?

Hi Guys,
I'm trying to generator random numbers between 0 and a map width and another random number between 0 and a map height i.e if the map width was 3 i can generator 0,1,2.
The coding i am using to do this is :
int randomCol;
int randomRow;
randomCol = newMapWidth - 0 + 1;
int itemp = generator.nextInt() % randomCol;
if (itemp < 0)
itemp = -itemp;
randomCol = 0 + itemp;
randomRow = newMapHeight - 0 + 1;
int jtemp = generator.nextInt() % randomRow;
if (jtemp < 0)
jtemp = -jtemp;
randomRow = 0 + jtemp;I've had a look at similar problems and searched penalty but can't seem to get it right for whatever way i implement. It leads to some array out of bound errors.
If any can help me resolve this problem it would be greatly appreciated.
Thanks A lot !

Hippolyte wrote:
randomRow = 0 + jtemp;I'll bite: what's the "0 + " voodoo for?It?s for clarity and Code readability, I guess. @OP: Random.nextFloat() generates numbers from 0.0f to 1.0f. Multiplying this number with your max value will generate a number between 0 and that given max value. BTW, you can generate numbers from -a to a by using (Random.nextFloat()- .5f) * (2 * a).

Generating random numbers, while excluding some numbers

I want to generate random numbers between 1 and 13 (including 1 and 13), while excluding numbers 6 and 9
Please tell me theres an easy fix to this issue --

lemme know if it compiles
import java.util.*;

public static void main( String[] args) {
int numWins = 0;
for( int i = 1; i < 101; i++) {
boolean x = true, y = true;
int number = 0;
while(!x && !y && number != 6 && number != 9)
number = 1 + (int) (Math.random() % 13);
x = number >= 1;
y = number <= 13;
int number2 = 0;
