nut is nutrition software to record what you eat and analyze your meals for nutrient composition. The database included is the latest USDA Nutrient Database for Standard Reference. This database contains values for vitamins, minerals, fats, calories, protein, carbohydrates, fiber, etc., and includes the essential polyunsaturated fats, Omega-3 and Omega-6. Nutrient levels are expressed as a percentage of the Daily Value, the familiar standard of food labeling in the United States, but also can be fully customized. Foods can be added from recipes or food labels, and nutrient intake can be graphed. The program is completely menu-driven and there are no commands to learn.
PLOTICUS is a command line utility for creating bar, line, pie, boxplot, scatterplot, sweep, heatmap, vector, timeline, Venn diagrams, and other types of charts and plots. ploticus is good for automated or just-in-time graph generation. It handles date, time, and categorical data nicely, and has some basic statistical capabilities. It can output to GIF, PNG, SVG, SWF, JPEG, PostScript, EPS, and X11. You can use convenient preset options or create complex scripts with rich and detailed color and style operations.
VMD (Visual Molecular Dynamics) is designed for the visualization and analysis of biological systems such as proteins, nucleic acids, lipid bilayer assemblies, etc. It may be used to view more general molecules, as VMD can read standard Protein Data Bank (PDB) files and display the contained structure. VMD provides a wide variety of methods for rendering and coloring a molecule: simple points and lines, CPK spheres and cylinders, licorice bonds, backbone tubes and ribbons, cartoon drawings, and others. VMD can be used to animate and analyze the trajectory of a molecular dynamics (MD) simulation. In particular, VMD can act as a graphical front end for an external MD program by displaying and animating a molecule undergoing simulation on a remote computer. VMD uses OpenGL and OpenGL Programmable Shading Language for high performance rendering of large structures.
RTLab is an RTLinux/RTAI-based data acquisition and control application. It is designed to help experimenters design and implement their hard realtime control experiements using higher abstractions than the services offered by RTAI or RTLinux. It is split into two parts. One is a user-space series of C++ classes (written for Qt) which implement a reference application called DAQSystem which is designed to acquire analog input voltage data and display it on the screen. DAQSystem communicates with rtlab.o, the realtime kernel module which is the second part of RTLab. The rtlab.o realtime kernel part is a kernel module that loads into RTLinux or RTAI and is responsible for driving COMEDI hardware for the purposes of data acquisition and realtime control. The module is extensible and features a 'plugin' architecture so that scientists who are savvy C programmers can easily leverage the existing framework for their own custom experiment logic. Experiment logic is specified by writing a kernel modules that gets called back for each scan rtlab.o acquires from the COMEDI hardware. In addition, data visualization and storage facilities exist in user space so that experimenters can instantly see graphical plots of their analog input data as it comes in from the hardware.
Brook for GPUs is a compiler and runtime implementation of the Brook stream programming language for modern graphics hardware. The goals for this project are to demonstrate general purpose programing on GPUs, to provide a useful tool for developers who want to run applications on GPUs, and to research the stream language programming model, streaming applications, and system implementations.
Devices for the measurement of signals use different data formats to store the data on disk. libRASCH provides a common application programming interface to access such signals, regardless of which storage format is used. Additionally, it provides support for processing (e.g. detects beats in an ECG) and viewing the signals. This functionality and the access to the various file formats is realized with plugins.
GATE is a software package dedicated to numerical simulations in medical imaging and radiotherapy. It supports simulations of Emission Tomography (Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT)), Computed Tomography (CT), and Radiotherapy experiments. It makes it easy to use existing Monte Carlo simulation packages according to the requirements of a simulation. It allows accurate description of time-dependent phenomena such as source or detector movement and source decay kinetics. It includes well-validated physics models, geometry modeling tools accommodating complex scanner geometries, models for detector electronic response, and efficient visualization utilities. Modelling of CT scans and calculation of dose can also be performed.
