pipasic
pipasic: Protein Abundance Correction in Metaproteomic Data
...These challenges are similar but not identical to the challenges arising in the analysis of metagenomic samples and require specific solutions. pipasic (peptide intensity-weighted proteome abundance similarity correction) is a tool which corrects identification and spectral counting based quantification results using peptide similarity estimation and expression level weighting within a non-negative lasso framework. pipasic has distinct advantages over approaches only regarding unique peptides or aggregating results to the lowest common ancestor. -

Speaker Recognition System
Speaker Recognition System - Matlab source code
...This technique makes it possible to use the speaker's voice to verify their identity and control access to services such as voice dialing, banking by telephone, telephone shopping, database access services, information services, voice mail, security control for confidential information areas, and remote access to computers. Speaker identity is correlated with the physiological and behavioral characteristics of the speaker. These characteristics exist both in the spectral envelope (vocal tract characteristics) and in the supra-segmental features (voice source characteristics and dynamic features spanning several segments). Index Terms: speaker, recognition, verification, sound, words. -

MusicPlayer
Music player - endlessly plays your music
This music player is supposed to be simple and all centered around an infinite intelligent queue (some other players call this PartyShuffle or DJ mode). You can manually add songs to it - but if you don't or the queue gets too short, it will automatically intelligently fill it with further songs. The intelligent queue decision currently is based on: * song ratings * context-based choices, e.g. related songs more likely Other features of this player: * open source, simplified BSD... -

Pepgrep
Tool for peptide MS2 pattern matching in MS tandem dataset
pepgrep offers a quick and friendly way to examine MS tandem output data by finding a spectral pattern matching selected peptide sequence. It is database-free command-line utility that uses Peptide-to-MS2 scoring algorithm. The Peptide-to-MS2 pattern matching can accumulate dozens of mass offsets corresponding to a variety of Post-Translational Modifications. Decoy peptide sequences are used with the tested peptide sequence to reduce false-positive results. -

TPFA-the answer book
Solutions of problems in functional analysis
The goal of the 5 Volumes of Theorems and Problems in Functional Analysis - The Answer Book is to provide the complete solutions for the exercises compiled in the ”core book” by A.A Kirillov and A.Gvichiani, ”Theorems and Problems in Functional Analysis, MIR editions, 1979” (TPFA). The problems cover most of the concepts of classical Functional Analysis: Distributions, Hilbert Spaces, Harmonic Analysis, Spectral Theory... The 828 exercises provided in TPFA represent an incredibly rich source of problems in order to train oneself in these fields. These exercises also bring numerous original entry points for various subjects outside the field of the theory developed in the core book. Finally, it is important to note that while the volumes are obviously naturally bundled with the core book, they have been written completely independently of it... -

Fast Solver for Potential and LFFFs
This is a fast solver for global potential field in the Solar Corona
...The global potential field and the LFFF are dealt with in an unified way by solving a three-dimensional Helmholtz equation in spherical shell and a two-dimensional Poisson equation on the photosphere. The solver is based on a combination of the spectral method and the finite-difference scheme. In longitude direction the equation is transformed into Fourier spectral space and the resulted 2D equations in r–θ plane for the Fourier coefficients are solved by finite difference in a direct way. The solver shows a distinguish virtue of extremely fast computing speed, e.g., the computation for a magnetogram with resolution of 180(θ) × 360(φ) is completed by only less than two seconds and even on a very high resolution 600 × 1200, the solution can be obtained within about one minute on a single 2.66G CPU.
