Why do I receive a segmentation violation when I try

 Why do I receive a segmentation violation when I try to access my BASLER A601fc DCAM compliant 1394 camera using Image Acquisition Toolbox 1.8 (R14SP2)?

I am using the CMU DCAM driver 6.3.0.0 (1394Camera.dll) with BASLER A601fc DCAM compliant 1394 camera. When I try to create a video input object using the following function:

 

vidobj =videoinput('dcam')

MATLAB issues the following segmentation violation:

   [0] imaqmex.dll:private: void __thiscall IMAQRoot::initTriggerStatus(void)(0x03512e50, 0, 0x0e336a70, 3) + 120 bytes

This bug has been fixed in Release 2006b (R2006b). For previous product releases, read below for any possible workarounds:
 
We have verified that there is a bug in the Image Acquisition Toolbox 1.8 (R14SP2) in the way that it handles this particular type of DCAM format 7 Camera.
 
To work around this issue, try using one of the non-format 7 modes of the camera, which has almost the same resolution as the format 7 mode, as follows:
 
vidobj = videoinput('dcam', 1, 'Y422_640x480');

You can find the supported formats of your camera by running the IMAQSUPPORT function. For more information regarding this function, type the following command at the MATLAB command prompt:

help imaqsupport
You can view the supported DCAM formats of your camera under the "DCAM ADAPTOR" section of the file produced by the above function.

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1.

Why are Fourier series important? Are there any real life applications of Fourier series?

A  Fourier series  is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series, which represents functions as possibly infinite sums of monomial terms. A sawtooth wave represented by a successively larger sum of trigonometric terms. For functions that are not periodic, the Fourier series is replaced by the Fourier transform. For functions of two variables that are periodic in both variables, the trigonometric basis in the Fourier series is replaced by the spherical harmonics. The Fourier series, as well as its generalizations, are essential throughout the physical sciences since the trigonometric functions are eigenfunctions of the Laplacian, which appears in many physical equations. Real-life applications: Signal Processing . It may be the best application of Fourier analysis. Approximation Theory . We use Fourier series to write a function as a trigonometric polynomial. Control Theory . The F
