Distillation Designer v1.0.4 brings users a simple McCabe-Thiele method for designing binary distillation systems. It will be of use to students studying Chemical Engineering and is currently being offered as 'donation ware'.

Major Features:

1. Boiling Point Graph showing Vapour-Liquid Compositions.
   
2. q-Line calculation from component thermodynamic properties.
   
3. Manually defining the minimum reflux ratio.
   
4. Loading of Data files.
   
5. Plot of Reflux versus stages to help determine the optimal value.
   
6. Drag and Drop graphs direct to desktop.
   
7. Configurable printing of the 3 Graphs
   
8. Much better checking of input data before the McCabe-Thiele graph can be plotted.
   
9. Very basic help.

ANTLRWorks 1.3b brings users a novel grammar development environment for ANTLR v3 grammars, which combines an excellent grammar-aware editor with an interpreter for rapid prototyping and a language-agnostic debugger for isolating grammar errors. ANTLRWorks allows users to edit, visualize, interpret and debug any ANTLR 3 grammar through an easy-to-use graphical user interface.

ANTLRWorks helps eliminate grammar nondeterminisms, one of the most difficult problems for beginners and experts alike, by highlighting nondeterministic paths in the syntax diagram associated with a grammar. ANTLRWorks' goal is to make grammars more accessible to the average programmer, improve maintainability and readability of grammars by providing excellent grammar navigation and refactoring tools, and address the most common questions and problems encountered by grammar developers

Major Features:

1. Editor
   • Single window editing
   • Syntax highlighting
   • Rule navigation tree
   • Jump to rule or token definition
   • Go To Rule
   • Find usages of tokens or rules
   • Find and Replace using regular expression
   • Sensitive keyword, rule, and token auto-completion
   • Rules and actions folding
   • Tips and ideas
   • Auto-indentation
   • Refactoring - remove left recursion, extract or inline rule, etc.
   • Show generated lexer or parser code using syntax coloring
   • Syntax diagram display for lexer and parser rule
   • Show unreachable alternative(s) in syntax diagram
   • Display nondeterminism warning as ambiguous paths through the syntax diagram
   • Highlight decision DFA
   • Rule dependency graph
   • Export syntax diagram, NFA and parse tree to bitmap image or EPS file
   • Perforce integration
   • emacs key bindings (Mac OS X only)
   • Contextual menus
   • Print
2. Grammar interpreter
   • Dynamically interpreter any input text
   • Display parse trees as list or graph
3. Grammar debugger
   • Local or remote debugger
   • Language agnostic
   • Dynamic parse tree
   • Dynamic AST
   • Tree grammar debugging
   • Lookahead highlighting
   • Breakpoint in grammar
   • Breakpoint in input text!
   • Breakpoint on any events - LT, consume token, exception, etc.
   • Step over rule
   • Show corresponding grammar location and parse tree node for each input token
   • Detachable panels
4. Code generation:
   
   • ANTLRWorks supports code generation in any language that ANTLR knows how to generate via the output=language option.
   • For Java, however, ANTLRWorks knows how to build a test harness, compile everything, launch the parser, and connect to it--a great rapid prototyping feature when you can't use the interpreter because actions and/or semantic predicates must execute.

Enhancements:

• New Grammar Wizard
• StringTemplate Editor
• Custom test rig
• Run an input directly on the grammar

BOUML is cross-platform UML 2 tool box that runs under Mac OS X(Intel), Unix/Linux/Solaris, and Windows.
BOUML is very fast and doesnt require much memory to manage several thousands of classes, see benchmark.
BOUML is extensible, and the external tools named plug-outs can be written in C or Java, using BOUML for their definition as any other program. The code generators and reverses are ones of the pre-defined plug-outs included in the BOUML distribution.

Main features:
- it is free
- it runs under Mac OS X, Linux/Unix/Solaris, and Windows thanks to Qt
- it allows to program simultaneously in C , Java, Php, Python and IDL
- thanks to a full access to the generated forms, you are the master and you decide what must be generated
- it is extensible, and the external tools may be developed in C or Java, using BOUML for their definition as any other program.
- it is very fast and doesnt require much memory to manage several thousands of classes

Enhancements
- Browser search allows now to search for elements depending on their stereotype.
- The menu miscellaneous has the new toggle completion in dialog, it is set by default to be compatible to the behavior of the previous releases. When it is set and you enter a string in a list of choices (combo box) in a dialog, an auto completion/search is done, note this one is non case sensitive (Qt limitation). If you dont like this auto completion/search, unset the toggle.
- Internal extension of the Plug-out API for Java Roundtrip.
- C++ Generator 2.13
- A dependency stereotyped friend produced a wrong code in case the target class was a template, fixed.
- Follow the new API.
- Plug-out upgrade 1.13
- A crash occured when you upgraded an old plug-out without Python management, fixed.
- Follow the new API.
- Java Roundtrip 1.0
- New plug-out, please refer to the documentation
- C++ Reverse 2.10
- Java Generator 2.17
- Java Reverse 2.13
- Java Catalog 2.12
- Idl Generator 2.10
- Php Generator 1.5
- Php Reverse 1.3
- Python Generator 1.1
- Roundtrip body 1.8
- Follow the new API.
- XMI Generator 1.4.6
- When a parameter of an operation doesnt have type the token UML:Parameter wasnt closed, fixed.
- XMI2 Generator 1.10.2
- The base type of a class stereotyped typedef is now produced in an extension form supposing you ask for them

UML implements UML statecharts in C++ and Java. Next to the standard elements of FSMs, hierarchical and concurrent states are as well supported as pseudostates, segmented transitions, timed events and an eventqueue using a thread pool.

Main features:
- Very easy to use API (See documentation for details)
- Implemented in C++ and Java
- Does require only a very small amount of memory
- Complete object-oriented design (all elements are real objects)
- Parallel usage of the statechart infrastructure. Runtime specific data is encapsulated in a small object.
- Support for many elements of statecharts
- Simple, hierarchical and concurrent states
- Start and final states
- History and deep-history pseudostates in hierarchical states
- Fork- and join pseudostates for concurrent states
- Segmented transitions using junction points
- Transitions can cross borders of composite states (implicit entry/exit)
- Entry, do and exit actions in states
- Events, guards and actions for transitions

System requirements:
- Java

Enhancements
- Fixed a ConcurrentModificationException bug when handling timeout events.
- Fixed shutdown procedure when the created threads are non-deamon threads.

jUML is a UML diagram application that is capable of reverse engineering Java source code to create relationship diagrams, source code generation based on a user created UML diagram, and saving/restoring of jUML projects.

System requirements:
-

Enhancements
- This is a working release. You can either import files to show relationships or create a new diagram and generate/test code and save the project.
