StatAssist displays graphs and related properties of more than 40 probability distributions. This application will save you time and prevent calculation errors if your work or study involves the use of continuous or discrete distributions. It allows to quickly select a distribution of interest, specify parameter values, and view the graphs - probability density, cumulative probability, survival, hazard, and cumulative hazard. You can easily export the results to various formats, or print them.

With StatAssist, you don't need complex statistical tables - it calculates moments, quantiles, and tail probabilities as you modify distribution parameters. In addition, it includes an efficient random number generator, a visual distribution gallery, and a comprehensive on-line documentation.

Supported distribution properties: min, max, mode, mean, variance, standard deviation, coef. of variation, skewness, and kurtosis.

Hermetic Stego allows you to encrypt and hide a message (the contents of a computer file) in another file so that the addition of the message to the container file will not noticeably change the appearance of that file. If the file which has been hidden is deleted then there is no indication that it even exists, but it can still be recovered when you need to get at it.

This program allows hiding a file of any size in one or more BMP image files, with or without the use of a user-specified stego key, so that (i) the presence of the hidden file is undetectable (even by forensic software using statistical methods) and (ii) if a user-specified stego key is used then the hidden file can be extracted only by someone, using this software, who knows that stego key.

Later versions of most web browsers will display BMP image files, so it is possible to conceal information within a picture on a web page.

Hermetic Stego allows two operations: (i) hiding a message file in single BMP image file or in a set of BMP images and (ii) extracting a message file from a single BMP image file or a set of them.

This program differs from others of this sort in two respects:

1. There is no limit on the size of the file to be hidden because Hermetic Stego can hide a message file, not just in a single BMP image file, but in a set of them -- as many images as needed to contain the message file.

2. The bits of the message are inserted into the bytes of the image files randomly and in such a way as to defeat the use of statistical tests to reveal the presence of a hidden message.

3. The program can be used with a user-specified stego key or with a default stego key; use of a default stego key allows sending a hidden message to another person who does not know what that stego key is.

The stego key (user-specified or default) is used not only to facilitate random selection of bytes for hiding message file bits but also is used to encrypt the message file.

The program "Data Holder" - is intended for carrying out of the warehouse and statistical account. As against similar software "Data Holder" differs simplicity of perception and does not demand any special skills for work and service. Due to differentiation of access rights to the data (reading only / full access) is excluded an opportunity of plunder by workers of commodity - material assets.

The software "Data Holder" ideally approaches for the decision of a lot of tasks where the control over quantity of various commodity - material assets and means is necessary.

The given program complex also can be used for creation of various helps and catalogues, providing a fast and convenient data access. Due to convenient system of reserve copying - restoration software can be quickly developed on a lot of computers of the enterprise.

Program Data Holder allows:

To differentiate access rights to tables with the data (reading only / full access)
To protect given by the password with the purpose of prevention of the non-authorized change of tables by foreign applications (including various databases editors)
To adhere a database to a concrete computer (makes impossible viewing / editing on other PCs)
It is convenient to process the tabulared data: to carry out search, to make sorting, to remember the size of columns of tables
To make import and export of tables to tabulared processor Excel
To carry out archiving and restoration of the data from archive directly in the program (the archive can be used for compact carry of the data on other PC, under condition of absence of binding of the data)
To order tables of data in alphabetic order
Software has the built - in calculator, a calendar, a notepad

For work "Data Holder" it is required OS Windows 98 and is higher, 64 MB than operative memory, and export of tables tabulared processor Excel is necessary for import established package MS Office XP
