A set of functions for the detection of spatial clusters of disease using count data. Bootstrap is used to estimate sampling distributions of statistics.

R-cran-epicalc is functions making R easy for epidemiological calculation.

Self-Organizing Map (with application in gene clustering)

The Blue Obelisk Data Repository lists many important chemoinformatics data such as element and isotope properties, atomic radii, etc. including references to original literature. Developers can use this repository to make their software interoperable.

Checkmol is a command-line utility program which reads molecular structure files in different formats and analyzes the input molecule for the presence of various functional groups and structural elements. At present, approx. 200 different functional groups are recognized. This output can be easily placed into a database table, permitting the creation of chemical databases with a functional group search option. Checkmol also outputs a set of statistical values derived from a given molecule, which can also be used for quick retrieval from a database. These values include: the number of atoms, bonds, and rings, the number of differently hybridized carbon, oxgen, and nitrogen atoms, the number of C=O double bonds, the number of rings of different sizes, the number of rings containing nitrogen, oxygen, sulfur, the number of aromatic rings, the number of heterocyclic rings, etc. The combination of all of these values for a given molecule represents some kind of "fingerprint" which is useful for rapid pre-selection in a database structure/substructure search prior to a full atom-by-atom match. Matchmol complements the capabilities of checkmol. It compares two (or more) molecular structures and determines whether one of them is a substructure of the other one. This is done by a full atom-by-atom comparison of the input structures. Thus, matchmol can be used as a back-end program for structure/substructure search operations in chemical databases. The port installs both checkmol and matchmol.

Chemtool is a program for drawing organic molecules easily and store them as a X bitmap file (develop version).

CLHEP is intended to be a set of HEP-specific foundation and utility classes such as random generators, physics vectors, geometry and linear algebra.

FastCap computes self and mutual capacitances between ideal conductors of arbitrary shapes, orientations and sizes. The conductors can be embedded in a dielectric region composed of any number of constant-permittivity regions of any shape and size. The algorithm used in FastCap is an acceleration of the boundary-element technique for solving the integral equation associated with the multiple-conductor, multiple-dielectric capacitance extraction problem. The linear system resulting from the boundary-element discretization is solved using a generalized conjugate residual algorithm with a fast multipole algorithm to efficiently compute the iterates. --------------------- This version of fastcap has been cleaned up and enhanced by Stephen R.
