Calculon
|
|---|
Calculon is a free2, tiny desktop calculator for Microsoft Windows (98, 2000, XP, Vista) that calculates by evaluating expressions instead of emulating a traditional desk calculator. Calculon is extremely extendable which means you can use it to solve practical problems such as “How long will it take to download this file?” and so on3.
The ideal usage pattern for Calculon goes a bit like this: launch Calculon with a hotkey, type or paste in the calculation, press enter and copy the result.
Calculon ships with predefined constants, functions and units but anyone can easily add the functionality they need. If you are a historian, you can add ancient measures or if like to cook, you can make Calculon convert between teaspoons and gallons if that is what you need.
Some of the key features:
- Lean and mean - designed for keyboard use, minimal UI kludge.
- Evaluates expressions - makes it easier to fix typos and minimizes the need to retype long calculations. Just type in the full equation and press enter.
- Unit, currency and other conversions - you can mix inches, metres, nanoseconds, kelvins, radians and hectares with no need converting measures to a common base.
- Extendable - units, functions, conversions and constants can be added and customized.

Calcute
|
|---|
|
Calcute is more evolved than regular calculators. It is in fact an expression evaluator. Unlike limited hand-held devices where numbers disappear as soon as you enter the next one, Calcute lets you enter a complete Advanced Freeware Calculator expression as if you were using a regular text editor. You can see what you are doing so you can easily make corrections. Simply type what you want to calculate, press Enter to get the answer. The calculator keypad can remain hidden or it can be shown if you prefer to click buttons with the mouse instead of typing.
You can stretch the display area to any size in order to retain and review past calculations, as if this were a paper tape calculator. But here you can also go back up the tape, edit past expressions and re-calculate them. You can even retain your work by saving everything to a file, to be restored later.
A number of interesting features are present in this little tool. Browse the site to learn about them, or just download the software and try it out. It's free! It's also clean: no spyware, no adware, nothing more than this handy calculator.

CALIB
|
|---|
|
The Quaternary Isotope Lab C14 calibration program, available for both Windows and Apple platforms.
CALIB 4.4 uses the 1998 international calibration datasets.
Conventional radiocarbon ages have been corrected for isotope fractionation by normalizing to = -25‰ PDB or VPDB. CALIB 4.4 no longer supports the correction for isotope fractionation within the program for the following reason: The d13C correction depends on whether the original measurement was a 14C/12C ratio (all radiometric and some AMS) or a 14C/13C ratio (some AMS systems). An Excel spreadsheet with the formulas for both types of systems is given here. If you don't know which type of measurement was done it is better to contact the laboratory which supplied the radiocarbon date.

Cambrium
|
|---|
|
This is the second version of Cambrium, an evolutionary simulation. The Cambrium world is a two-D world filled with little green plants that contain energy. Normally, gravity keeps the plants towards the centre of the world where there is most light and the grow best.
The interesting part starts with the animals that crawl around in the cambrium world. They are all circles with on the edges different body parts: eyes, moving tails, mouths and brain cells. The eyes peer in a direction and see colors, red, green and blue. The tails can move the animals forward. Mouths eat if they get into touch with food or even other animals. Body parts have inputs and outputs. How fast a tail moves depends on the input, while the three output of eyes depend on what colors they see. Body parts can be connected by simple formula’s. Let’s have a look at a typical animal in Cambrium world.

Cartes du Ciel Sky Charts
|
|---|
This program enables you to draw sky charts, making use of the data in 16 catalogs of stars and nebulae.
In addition the position of planets, asteroids and comets are shown.
The purpose of this program is to prepare different sky maps for a particular observation.
A large number of parameters permit you to choose specifically or automatically which catalogs to use, the colour and dimension of stars and nebulae, the representation of planets, the display of labels and coordinate grids, the superimposition of pictures, the condition of visibility and more.
These features make this celestial atlas more complete than a conventional planetarium.
Note: Available in 24 other languages.

Caterpillar
|
|---|
|
The 16-bit Caterpillar program performs analysis of one-dimensional time series. It supports two languages (English and Russian) and needs Windows 3.1/9x/NT/2000/Me. The program is freeware.
Features of Caterpillar 1.00
- Decomposition of one-dimensional time series into eigentriples (eigenvalues, eigenvectors and principal components)
- Convenient graphical visualization of results for identification of the eigentriples corresponding to trend, periodicities, noise
- Reconstruction of time series components (trend, oscillations, periodicities, noise) by choice of eigentriples

CC-Plot
|
|---|
CC-Plot is a simplified DOS based GIS for working with piece provenienced artifact data. It allows the user to map any group of square or levels, to color code the map by artifact type or level, and to link the artifacts on this map to their respective records in associated databases. This program was developed by Harold L. Dibble and Shannon P. McPherron to deal with the data coming from the excavation of Combe-Capelle Bas, France. Several others, however, have converted their own datasets into the same format and are using the program. The data set distributed here with the program consists of only one unit from Combe-Capelle Bas. To obtain the full data set, you can either purchase the Combe-Capelle CD-ROM or download it from our web site.
Because the program is written in DOS, it will run on a wide range of computers and requires extremely little in the way of computer resources. It has been tested on Windows 95 and 98. It very likely runs on Windows 2000/XP/ME as well. We now use a Windows based version of this program (Plot).

CDPro
|
|---|
|
A Software Package for Analyzing Protein CD Spectra
CDPro software package consists of three of the popular programs (softwares) for analyzing the protein CD spectra for determining the secondary structure fractions (SELCON3, CDSSTR, and CONTIN) and a program for determining tertiary structure class (CLUSTER). These programs can now be run in a browser (Netscape Navigator) environment with ease.The program CONTIN has been modified to include the variable selection of reference proteins in the locally linearized model. The valid solutions from the variable selection are selected using the new selection rule (Helix_Rule) proposed by Johnson. This new selection rule is also incorporated in SELCON3.
