    physicsmata

    API for all possible cellular automata that work same at all angles

    ...You can create any function, or to get started try the visual function editor where each click changes if a column is sine/sigmoid/half/double/exp/etc or which of the 0, 1, or 2 columns to the left are its params. Every click changes the patterns of waves seen on the left, which run that function you visually built at each point.

    EDM Calibration Baseline Fitting

    EDM Calibration Baseline Fitting

    EDMFit is an adjustment tool to estimate EDM calibration parameters.

    ...EDMFit is a simple adjustment tool to estimate the EDM calibration parameters (addition constant and/or scale parameter). The adjustment process is according to ISO 17123-4. The parameters are checked for significance, to avoid an overestimation. Based on two classical hypothesis testing, EDMFit provides a reliable outlier detection. For uncertainties budgeting, EDMFit makes use of Monte-Carlo simulations and supports different distribution function: - Uniform distribution, - Triangular distribution and - Gaussian (normal) distribution. For refractive index determination, the application supports the following models: - Barrel and Sears (1939), - Edlen (1953, 1966), - Owens (1967), - IAG (1999) and - Ciddor (1996, 2002). ...

    Logic Calculator

    A Calculator 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.

    Bit level lambda continuations and nothing else - Queue automata

    Not working yet. To deal with the Halting Problem, computing and data are navigated using debugger ops: linearForward and treeForward, which navigate an astronomically large bit string where 1 is ( and 0 is ). All pairs are derived from (). For example, true is represented as ((()())()), and false is (()(()())). It appears related to the church encoding of lambda where T chooses first parameter and F chooses second, of a pair. Continuations are nearly finished code and are represented as a...

    Immutable Sparse Wave Trees (WaveTree)

    Realtime bigdata tool for bit strings up to 2^63 based on AVL forest

    Realtime bigdata tool at the bit level based on immutable AVL forest which can be run in memory or, in future versions, as a merkle forest like a blockchain. Main object is a sparse bit string (Bits) that efficiently scales up to 2^63 bits normally compressed as forest has duplicated substrings. Bits objects support reading bit, byte, short, int, or long (Java primitives) at any bit index in 64 bit range. Example: instead of building a class to hold a header and then data, represent all of that as Bits, subranges of them, and ints for sizes of its parts. Expansion ability for other kinds of compression, since Bits is a Java interface. ...

    ...We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity in practical situations significantly.

    The Harmony of the World

    A fair attempt at the Keplerian tradition to explore the solar system

    ...Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity. The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a Java Virtual Machine (Rev 1.5 or greater). JAVA 2, system independent. Purpose:to encourage research in harmony in astronomy, math and music. Obstacles:math, DSP/synthesis, networks, astronomy. ...
