CRC RevEng
Arbitrary-precision CRC calculator and algorithm finder
CRC RevEng is a portable, arbitrary-precision CRC calculator and algorithm finder. It calculates CRCs using any of the 113 preset algorithms, or a user-specified algorithm to any width. It calculates reversed CRCs to give the bit pattern that produces a desired forward CRC. CRC RevEng also reverse-engineers any CRC algorithm from sufficient correctly formatted message-CRC pairs and optional known parameters. It comprises powerful input interpretation options. Compliant with Ross Williams' Rocksoft(tm) model of parametrised CRC algorithms. -

Error Propagation Calculator
Easily propagate measurement errors through mathematical operations.
Error Propagation Calculator is essentially a cross-platform GUI front-end for the Python Uncertainties library that does not require knowledge of Python to use. Simply point and click to enter values and errors, input your expression and press compute. The program evaluates native Python code, but the user does not need to know the syntax as common operators are provided as buttons, similar to a scientific calculator. -Evaluate expressions with as much as 26 different variable and error pairs. -Copy output to the system clipboard by simply double clicking the output field. -Cross-platform: Works on Windows, Linux, and Mac. All calculations are dependent on the uncertainties package (Uncertainties: a Python package for calculations with uncertainties, Eric O. LEBIGOT, http://pythonhosted.org/uncertainties/) -

Logic Calculator
A Calculator to perform logical operations
The Logic Calculator is an application useful to perform logical operations. It has three modes: (1) Evaluation of logic formulae: In this mode we have the basic boolean operations (negation, conjunction, disjunction, conditional and biconditional) so the user can insert the logic formula and the Logic Calculator displays the truth table along with the models of the formula. (2) Logical entailment: In this mode the user can insert a number of premises followed by a number of conclusions, so the Logic Calculator displays the truth table of each premise / conclusion and the result of whether or not these premises logically entail the given conclusions. (3) Conversion of a formula to Disjunctive Normal Form (DNF) and Conjunctive Normal Form (CNF): In this mode the user inserts a logic formula and the Logic Calculator outputs its representation in both a DNF and CNF. -
