UltimaCalc is a collection of mathematical tools wrapped up in one program, for use by scientists, engineers and students. The main window is a calculator that accepts mathematical expressions as plain text and evaluates them to 38 digit precision.
UltimaCalc can remain always ready for use. The use of text input means that this window can be small enough to remain open at all times without blocking the view of other windows. This window can be partially transparent when inactive, so you can read documents open underneath it.
A major feature of UltimaCalc Professional is its Symbolic Algebra module: Simplify expressions, differentiate them. Integrate a wide range of expressions, and see how the result was obtained. Find Taylor series. Factorise polynomials, divide one polynomial by another or find their GCDs.
Analyse a set of measurements, or approximate complicated functions with simpler ones. Use a variety of methods to fit lines to data, plotting the result. Calculate linear regression, or use an absolute deviation fit to minimise the distorting effects of outliers. Perform a multivariate linear regression when one variable is a linear function of several others. Fit polynomials and other non-linear expressions to the data.
The Standard Deviation tool calculates the mean, median, standard deviation, skewness, etc of a data set.
Other tools solve simultaneous linear or non-linear equations; find the values of parameters that minimise the value of an arbitrary expression; find roots of polynomials up to tenth order; or solve triangles.
Plot arbitrary functions. Specify starting and ending conditions and how variables X and Y change at each step. Combine up to 8 plots.
Save your results: the calculator window and most special tools can record all calculations in a plain text file. Most special tools can also save their data along with notes to a calculation file future reference. All graphs and plots can be saved as image files in a variety of formats.

The Universal Product Code has been used in the North American retail industry since 1973. There are two different versions of UPC bar codes, UPC-A and UPC-E. The UPC-A bar code is 12 digits long, including its checksum. UPC-E bar codes are special shortened versions of UPC-A bar codes and are 6 digits long. Both UPC-A and UPC-E bar codes may have optional 2 or 5 digit supplemental codes appended to them.Our scalable TrueType and PostScript bar code fonts comes in five different aspect ratios, so you can vary the height and width of the bars independent of each other. This lets you print bar codes with the same height, but different horizontal print densities. The online manual comes in Rich Text format. Just print a copy of the manual to see how to use these fonts to print bar codes.UPC bar codes encode fixed length numeric data. A checksum is required, and checksum calculation is complex. VBA functions for Access and Excel make using our fonts in those programs a breeze. Our bar code set includes BARUPC.EXE a utility, which builds bar code strings and generates checksums for you and Word label templates. The BarUPC program can export bar codes as bmp, gif, or jpg graphic files.

CRC32 Static Library for Microsoft VC++ was produced to make your CRC checking operations quick & easy to implement seamlessly without the need for an external DLL

The CRC is a "digital fingerprint" of a file, With CRC32 you can "melt down" a huge 20 MB (or even much bigger) file to have a small, handy reference to it, a single 32-bit number like 7d9c42fb (hexadecimal notation) which would unambiguously reflect the entire contents of this huge file. Now if some changes to this file happened, no matter how small, maybe only a single wrong bit somewhere in the middle, a new CRC-32 calculation would yield a completely different reference number (say 3faa83bd). So there’d be no doubt about it - this is not the same file anymore. On the other hand if the reference number was still the same (7d9c42fb) you might be sure that the file hasn’t changed.

The algorithm of CRC32 is exactly the same as that internally used by PKZIP and WinZip; i.e. the CRCs calculated by PKZIP and CRC32 are identical. That’s another fine thing about CRC32 - it calculates compatible, widely used 32-bit checksums, not just any numbers. You can use the 'pkunzip.exe -vt filename.zip' command to see that PKZIP’s CRC-32 values of files stored inside the filename.zip are identical to that calculated by CRC32 for these files.

Though you can use CRC32 to calculate 32-bit checksums of any file the real strength and usefulness of CRC32 is in comparing Wave Sound Files to see if their non-silent music parts are identical. In particular CRC32 may come in handy when comparing two different extractions of a CD Digital Audio track to ensure that the performed digital copy is perfect.

The program allows you calculate pension annuities and/or pension contributions for non-state pension funds, based on actuary mathematics. The software can use various gender stats, investment rates to execute calculations for various short and long-term pension schemes: fixed-term or whole life pension, whole life pension with/without cash refund period, contribution for receipt of whole life fixed-term pension with/without cash refund period, pension payment and cash refund period, annual benefit amount for fixed-term pension.
The software will be useful as well for participants to estimate a correctness of your pension calculation and regular payments of non-state pension made in accordance with the pension scheme due to set of conditions determining the pension process, vesting period termination, surrender value payment, investment income, etc.. In order to calculate pension annuities and/or pension contributions you will need to input the year of your birth, gender, accumulation period, amount of contributions, and other conditions.

OilProp is designed to assess the core thermophysical properties of oil and its derivatives necessary to solve transportation and processing tasks, with the minimum volume of input data. It is based on regularities and statistics generally known in the area. OilProp solves the following tasks:
1. Basic Calculation - calculation of thermophysical properties at the atmosphere pressure and the temperature 20 deg.C (68 deg. F).The calculation results are used for hydraulic analysis of pipelines as well as in design of equipment intended for storage, thermostating, transportation, mixing, spraying homogenization of oil and its derivatives.
Density and / or fractional composition of the substance are used as input data (the calculation is more precise if fractional composition is given).
The program calculates density (if not given), isobaric specific heat, thermal conductivity, kinematic viscosity, average saturated vapor pressure, surface tension, the Prandtl number, and pseudocritical temperature.
2. Additional Calculation - calculation of thermophysical properties of a substance in liquid and gas phases at given absolute pressure and temperature within the under-critical range. The calculation results are used for process modeling and design of equipment intended for processing of oil and its derivatives, for hydraulic and aerodynamic design of pipelines at steady and non-steady temperature, as well as to find out heat exchange process characteristics, etc.
Additional input data, besides temperature and pressure, are density and/or fractional composition (calculation is more precise when fractional composition is given).
The program calculates the percentage of liquid and gas phases, density, isobaric heat, thermal conductivity, vaporization enthalpy, kinematic viscosity, surface tension (for the liquid phase only), and the Prandtl number.

The principle of this puzzle game is very easy to understand. Using the mouse, you must clean the screen of all Zanitos so that your name none remains about it. You will also have to try to obtain the best possible score and to maintain it throughout the party. For that, you must eliminate the most Zanitos identical in only one blow and as well as possible use the no-claims bonus which are on the screen of play. Avoid losing credits or the Game Over will get you… You will have only a few seconds of reflection before the calculation of the points starts. Do not lose too much time and hurry up to gain 25000 points in order to obtain an additional credit. New graphic and musical features await you in the final version of the play, more credits also from the beginning. For the registered users, the best scores on line are not erased after 24 hours and the Game is guaranteed to life as are every other TLK Games products. The warning messages will disappear and you will not need to wait at the start of the play. TLK games grants a life long guarantee for updates for the registered version of this game.
