librsb
A shared memory parallel sparse matrix library including Sparse BLAS.
....: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents. -

Meaning Explorer
A tool for analyzing the words of the Quran
...The Meaning Explorer applies a new distributional semantic model to extract words’ significant co-occurrences from the Quran. This model is based on the Refined MI association measure applied to all words within a symmetric sliding window of five words surrounding the node word. The Refined MI association measure is chosen because of its remarkable ability ability to extract syntagmatic relations between the words of the Quran. -

LightPCC
Parallel pairwise correlation computation on Intel Xeon Phi clusters
...This library is written in C++ template classes and achieves high speed by exploring the SIMD-instruction-level and thread-level parallelism within Xeon Phis as well as accelerator-level parallelism among multiple Xeon Phis. To facilitate balanced workload distribution, we have proposed a general framework for symmetric all-pairs computation by building provable bijective functions between job identifier and coordinate space for the first time. -

piv_clustering
structural clustering of atomic trajectories based on PIV
...At variance with other approaches, it is possible to analyse also processes in solution, e.g., chemical reactions in liquid water, since the distance metric is based on a Permutation Invariant Vector (PIV) that is symmetric under exchange of identical atoms or molecules, including on the same footing both solute and solvent degrees of freedom. The approach is general and the definition of PIV only requires to specify the range of interatomic distances that is relevant for the process under study. Alternatively, also the SPRINT topological coordinates can be employed, that are particularly suited for nanostructures. ... -

Set Theory Relations in Java
Java classes implementing set theory relation concepts
Simple java classes implementing basic concepts of relations as defined in set theory. A relation is a set of ordered pairs. A relation can have properties, including that it is reflexive, symmetric, or transitive. The classes enable some ordered pairs to be stated, and will deduce all the other related ordered pairs implied by the relation's properties. There are implementations of transitive, reflexive-and-transitive, and symmetric-reflexive-and-transitive (equivalence) relations using hash sets and tree sets. The current version (0.1) has been tested but not substantially used. ...
