Lattice: A package to model accelerator lattices and beam lines
https://www.maplesoft.com/applications/view.aspx?SID=153970&ref=Feed
The Lattice package is a Maple package to design and analyze charged-particle beam lines and circular machines. It employs a beam-line description using the standard elements (dipoles, quadrupoles and so on) and retains the algebraic power of Maple. Beam-line elements are described using the equations governing the particle motion in algebraic form. In this way it is possible to compute expressions for beam-line parameters like Twiss functions, dispersion and such, for beam
lines or rings, and to perform analysis on these expressions using the full power of Maple.<img src="/view.aspx?si=153970/Lattice.png" alt="Lattice: A package to model accelerator lattices and beam lines" align="left"/>The Lattice package is a Maple package to design and analyze charged-particle beam lines and circular machines.

https://www.maplesoft.com/applications/view.aspx?SID=153555&ref=Feed
<p>Nonlinear model predictive control (NMPC) has attracted attention in recent years. The continuation method combined with the generalized minimal residual method (C/GMRES) is well known to be a fast algorithm and is generally suitable for real-time implementation. This package provides a symbolic computation tool that automatically generates code for use in nonlinear predictive control design environment based on C/GMRES. Interaction with the package is done through an easy-to-use document interface.</p>
<p>Note: Requires Maple 17 or later and a C compiler.</p>

<p>This is an update, labeled version 1.1, to the existing application The Advanced Encryption Standard and its modes of operation.</p>
<p>Version 1.1: Key generation function and related functions updated to facilitate the use of externally generated seeds. Some minor changes to presentation.</p>
<p>Version 1.0: Implementation of encryption and authentication schemes that use the Advanced Encryption Standard (AES) as their underlying block cipher. These schemes are constructed by using all the modes of operation for block ciphers so far approved by NIST (the US National Institute of Standards of Technology), namely, the five confidentiality modes: ECB, CBC, CFB, OFB and CTR, the authentication mode CMAC, and the "authenticated encryption" modes CCM and GCM/GMAC. The implementation is able to encrypt/decrypt and/or authenticate messages in several formats, including binary files, and we use it to explore the basic properties of these schemes. The implementation contains also detailed explanations of all the procedures used, including the lower level ones, and discusses both the programming and the cryptographic aspects involved.</p><img src="/view.aspx?si=6618/AES_1608.gif" alt="The Advanced Encryption Standard and its modes of operation" align="left"/><p>This is an update, labeled version 1.1, to the existing application The Advanced Encryption Standard and its modes of operation.</p>

Statics is a package of Maple routines for calculations in engineering statics, developed by Dr. Harald Kammerer of GERB in Berlin, Germany. All routines are available through a maplet and top-level commands.
Using the Statics package, a civil engineer can input a basic structure along with its load and material parameters, and instantly derive the essential properties of the loaded system. The package can give results in both symbolic and numeric form. Available calculations include:
* Deformation functions for 14 classes of bars and beams
* Principle stresses, strains and moments of inertia for beam cross-sections
* Bar forces and support reactions within 2-D and 3-D frameworks
* Center of gravity, area and second moments of rectangular, triangular, circular, and I-, L-, U-, and T-profile cross-sections, as well as combinations of them.<img src="/view.aspx?si=4682/statics_logo.gif" alt="Statik auf Deutsch" align="left"/>Statics is a package of Maple routines for calculations in engineering statics, developed by Dr. Harald Kammerer of GERB in Berlin, Germany.
