Thus, the audio output provides an overview of the general shape of the graph. The data output is available for detailed quantitative analysis.

The file named Sinc01Solver .bat

Continuing with the explanation of Sinc01 , Listing 17 shows the contents of the file named Sinc01Solver.bat . (This is a Windows batch file. A file with a similar purpose on other operating systems would be different.) If you have the Java Development Kit installed on your (Windows) computer, execution of this batch file will compile and execute the file named Sinc01.java . This will create the text file containing the data that is needed by the AudioGraph program named MusicComposer10 .

The file named Sinc01Player .bat

Listing 18 shows the contents of the file named Sinc01Player.bat . (Again, this is a Windows batch file.) If you have the Java Development Kit installed on your (Windows) computer, execution of this batch file will compile the file named MusicComposer10 and execute it twice. The first execution will cause the audio to be played immediately. The secondexecution will cause the audio to be saved in a file named Sinc01.au .

The zip file that you can download contains all of the files mentioned above for all of the functions illustrated by the audio in the above list . Simply extract the contents of the zip file into an empty folder, execute the ...Solver.bat files to create the data for the functions. Execute the ...Player.bat files to hear the audio for the functions and to write the audio into output audio files of type AU.

The class named MusicComposer10

This program requires the following five classes in the same folder. Source code files for all five classes are provided in the zip file that you can download.

  • AudioSignalGenerator02
  • AudioPlayOrFile01
  • AudioFormatParameters01
  • MusicComposer10
  • AudioGraph01

The first three classes in the above list have been used in many previous modules. Therefore, I won't discuss them further in this module. However, I will explainthe last two classes in the list.

A complete listing of the class named MusicComposer10 is provided in Listing 19 . As usual, I will break the class down and explain it in fragments.

This is a general purpose AudioGraph program that reads an input text file containing numeric values for y as a function of equally spaced values for xand produces an output melody that represents a graph of that data. The values for y are read as a comma-delimited list of values and are treated as type double . The name of the text file is input as a command-line parameter. Additional details will be provided later in the explanation of the class named AudioGraph01 .

The melody can be played immediately or can be saved in an audio file of type AU for playback later. You should be able to play the audio file with anystandard media player that can handle the AU file type

Beginning of the class named MusicComposer10

The class named MusicComposer10 begins in Listing 7 . Note the description of the command-line parameters in Listing 7 . Otherwise, there is nothing new or unusual about the code in Listing 7 so there should be no need for further explanation beyond the embedded comments.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
