Free look for software for windows

LOOK 08/08 is a free PC program designed for signal analysis and graphical display. It also performs some digital signal processing functions and can save the results to a disk file. Input is from data files stored on disk or signals generated within the program.

Free for personal or educational use. Capability includes Fourier transforms, windows, filters, resampling, differentiation, integration, autocorrelation, convolution, crosscorrelation, and statistics.

Major Features:

1. LOOK can read time or frequency domain input signals from disk:
   • Real time domain data
   • Complex time domain data
   • Real frequency domain data
   • Complex frequency domain data
2. LOOK can read two independent real or complex signals of any type.
3. LOOK can generate real or complex signals from an arbitrary equation.
4. LOOK is intended for use with uniformly sampled data. That is, the sampling interval of the x axis (time, frequency or whatever) must be uniform throughout the data file. Non-uniformly sampled data is NOT supported except for the X-Y plot case.
5. The program can perform various signal processing operations:
   • Fourier transforms and inverse Fourier transforms
   • Windowing -- Cosine, Cosine-squared, Rectangular, Kaiser or notch.
   • Linear transforms -- add a constant, multiply by a constant, multiply by a complex exponential or multiply by a sinusoid
   • Filtering -- Chebyshev, Butterworth, Transitional, Bessel filter or arbitrary H(s) (Laplace transform). It will generate the filter functions and apply them to the input signal.
   • Change sampling rate -- upsample and downsample
   • Differentiation and integration
   • Autocorrelation
   • Convolution
   • Crosscorrelation
6. It can also graph, list or save to file various parameters of the input signal(s):
   • Real component
   • Imaginary component
   • Amplitude (absolute value)
   • Power
   • Phase
   • Instantaneous frequency (FM demodulation)
   • Group delay of filters
   • Deviation from linear phase
   • X-Y (Lissajous) graphs
   • Product of real and imaginary parts
   • Sum and difference of real and imaginary parts
   • Linear regression lines
7. It also computes:
   • Sliding window averages
   • Probability distributions
   • Cumulative distributions
   • Various statistics such as rms, mean, min, max, etc.

Enhancements:

• Include the ability to read wav files which have extra information included in the header (name of song and copyright notice).

Requirements:

• Windows 95 and higher
  

Look Up is a gadget that lets you look up words from dictionaries, wikipedia, stock quotes, and translations.
Once you set up dictionary in options, you can search any text from internet. Parser supports basic string match and regular expression, you can also use multiple input strings.
Here are some example of using Look Up:
Google Calculator:
"4 ounces in liters"
"12*2.3"
"44$ in won"
BabelFish Translation:
"fr_en/bonne chance"
You can directly specify dictionary:
"wiki:google"
"eng:cat"

is intended to track changes made to the system by setup programs Look@Win is a freeware program and is provided without any limitation at no charge to the user. If you find this program fast, convenient and useful, a little donation to the UNICEF or to your National Red Cross is encouraged by the author.
Look@Win is a free utility that was designed for tracking changes made to the system by setup programs. If you perform the installation of a program, you wont know if the setup will copy some files(i.e. DLL, VBX ) to your Windows (Tm) or Windowssystem directory. The amount of space required by Windows directories will enlarge, and if a specific uninstall program is not provided, you wont know what files could be safely deleted from Windows.
Running Look@win 3.53, after a program installation setup, will compare the actual status of Windows system with the recorded previous one, detecting changes. Inizialization files and Registry file control provides a sort of anti-virus function,too: if any difference will be detected, the new lines in .ini files or Windows Registry will be displayed, thus alerting for changes made by viral programs in order perform malicious actions at system startup.
Moreover detection of size changes of executable files in Windows directories adds possibilities of early discovering a viral attack to your system.

Look It Up adds eBay, dictionary, thesaurus, quotations, and eight popular search engines to IEs context menu. Highlight a word or phrase on any web page, right click your mouse, and a new browser windows appears with the definition or search results.
Search engines include Altavista, Ask Jeeves, eBay, Google, LookSmart, Lycos, MSN, Overture, and Yahoo. LookItUp supports four different Google searches: web, groups (usenet), news, and Im Feeling Lucky.
