Gnuplot is a popular portable free graphing software program for download. It is widely used on many platforms, including MS Windows, Linux, Unix, and OSX. It also retains support for older systems such as VMS, Ultrix, OS/2, and MS-DOS. The source code is copyrighted but freely distributed.
LabPlot provides an easy way to create, manage and edit plots. It allows youto produce plots based on data from a spreadsheet or on data imported fromexternal files. Plots can be exported to several pixmap and vector graphicformats.Features include: - project-based management of data - project explorer for management and organization of created objects in different folders and sub-folders - spreadsheet with basic functionality for manual data entry or for generation of uniform and non-uniform random numbers - import of external ASCII data into the project for further editing and visualization - export of spreadsheet to an ASCII file - worksheet as the main parent object for plots, labels, etc; supports different layouts and zooming functions - export of worksheet to different formats (PDF, EPS, PNG, and SVG) - great variety of editing capabilities for properties of worksheet and its objects - cartesian plots, created either from imported or manually created data sets or via mathematical equation - definition of mathematical formulas is supported by syntax highlighting and completion and by the list of thematically grouped mathematical and physical constants and functions - analysis of plotted data is supported by many zooming and navigation features - linear and non-linear fits to data, several fit-models are predefined and custom models with arbitrary number of parameters can be provided Tags: Interface Toolkit: Qt
For multi-DOF NPSs, the number of branched chains is not less than the number of DOFs. Depending on the arrangement of the mechanical branched chains, kinematic configurations of NPSs include CPMs, compliant serial mechanisms (CSMs), and compliant serial-parallel hybrid mechanisms (CHMs). The parallel-kinematic configuration, combined with equilateral symmetry and spatial geometry, limits thermal drift in position and orientation. This configuration holds a greater advantage for NPSs in that a high output stiffness, high payload, and excellent precision can be obtained simultaneously. As an example of in-plane 3-DOF (x, y, θz) NPSs, the 3-revolute-revolute-revolute (3-RRR) CPM has been proven to demonstrate advantageous mechanical performance, such as high rigidity and accuracy [1,3,4,5,6,9,10,11,12,13]. Many challenges with respect to the use of CPM to design spatial multi-DOF NPSs still need to be overcome.
