SWC Encrypt encrypts your Flash .SWC files, protecting them from the most popular Flash Decompiler Tools on the market! Secure your ActionScript in the Flash component and prevent SWF Reverse Engineering and Decompiling.

SWC Encrypt is designed for those who develop Flash .swc components and want to delivery them in security. SWC Encrypt used encryption technologies that can help user to prevent from the most popular decompiler tools on the market. SWC Encrypt provides high security and protection for your SWC Files.

It is quite easy to reveal all the .swc codes from a movie if you use the normal .swc component in your work. Almost all decompiler tools can do this job well. Even some decompiler tools like ASV can reveal codes from .swc file directly. But it is very hard to reveal .swc codes from a movie if you use encrypted .swc component in your work.

There isn't any tools can protect .swc file for years. For about two years hard work, Fenix Studio release this great tool. It is the best choice to protect ActionScript in Flash .swc component file. It is an easy-to-use tool. You can finish encryption process in senconds.

Sequence diagrams are a very effective way of modeling an object oriented system. Unfortunately, most UML based modeling tools only offer primitive support for sequence diagrams. EventStudio provides advanced constructs for sequence diagram based object modeling. EventStudio supports generation of message sequence charts (MSCs) and call flow diagrams used in telecom and embedded system development. Process workflow generation is supported for business process re-engineering applications.
When modeling with EventStudio, developers describe the interactions in the system in terms of a simple declarative modeling language. EventStudio then analyzes the model for design errors, inconsistent operations, resource leaks and invalid timer operations. Once the design issues have been addressed, EventStudio automatically generates sequence diagrams and collaboration diagrams.

EventStudio allows the developers to explore a large number of success and failure scenarios without the overhead of individually documenting each scenario. The developers define a base scenario and then define other scenarios by just specifying the differences with the base scenario. EventStudio manages the scenario definitions and generates the documents by merging the base scenario with the specified differences for each scenario.

EventStudio automatically handles diagram layout, formatting, scaling and page breaks for sequence diagrams and collaboration diagrams generated in the Adobe PDF and Microsoft Word Picture (EMF) formats. This allows the developers to focus on system architecture and design, without getting bogged down by document layout issues.

EventStudio has been designed to handle diagram generation for systems with a large number of interacting objects. For greater modularity, objects in the system can be classified into groups and sub-groups. This classification is used to generate diagrams that focus on a particular aspect of the system.

For a project of any kind it is most important to be able to describe the problem quickly and clearly. An innovative requirements development and analysis tool VR (Visual Requirements) is a practical, low-cost / low-risk solution for defining software, user interfaces, system components, processes, dashboards, information sources, etc. It can also be used as a general information management tool, for example, to organize ideas or references.

VR leverages lucid and efficient information structures that enable very productive work. For example, designing a website, we frequently find that the same field has to appear on several screens - where to keep the requirements related to this field and how to find them? Or, some scenarios or algorithms may have many identical elements - how to make the updates to these elements only once? Some requirements belong to use cases but also have to appear in supplementary specifications - what is the best way to deal with this?

VR provides simple effective functionality to:
* Build requirements as a set of linked diagrams that are easy to read and navigate
* Present a product in multiple views: concept view, use case view, user interface view, concept view, workflow view, and others
* Define use cases visually
* Create coherent intertwined structures with common elements, such as use cases, screen mockups, algorithms
* Instantly inquire about location, content and properties of concepts, data items, requirements; find elements by name, concept, substring; etc.
* Analyze your model, e.g. find orphan elements, compare diagrams, compare requirements, trace requirements, etc.
* Create reports using easy integration with Word and other tools
* Estimate size and effort using Use Case Points
* Etc.
VR is an evolutionary tool that is user friendly right from the start. Engage VR to dramatically increase the productivity of your work, the quality of your work products and the maturity of your process.

Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay's textbook 'Modern Spectral Estimation' 1988 is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameters and/or number of points may provide discrepancies. See how zero padding effects your results. Manufacturing companies take note! Some estimators can detect signals 50 to 100 dB from main signal. See documented example! The unwritten rule of '30 dB is okay' (i.e. hidden) is no longer true.

Database Designer for PostgreSQL is an easy CASE tool with intuitive graphical interface allowing you to build a clear and effective database structure visually, see the complete picture (diagram) representing all the tables, references between them, views, stored procedures and other objects. Then you can easily generate a physical database on a server, modify it according to any changes you made to the diagram using fast ALTER statements. Database Representation: Place objects of your database on a diagram, a virtual sheet of paper. See and realize the structure of your database and its objects: tables, views, stored procedures, functions and relationships between them. Construct schemas, domains, tables, indexes, columns and triggers. You can import already existing databases to a diagram by reverse engineering. Easy Database Generation and Maintenance: With the database designer you can quickly create a ready-to-use PostgreSQL database with a few clicks, and then keeping its structure up-to-date by synchronizing it with the changes you made to a visual diagram. Simply change the diagram - Designer will generate complex SQL statement for database modification to bring it to the state of diagram keeping data in safe. Moreover, you can synchronize several databases to the state of your diagram. Documentation: Printing, Generating Graphics and Reports: Generate powerful reports that describe all the database objects within your diagram. You can export graphical representation of diagram to EMF, JPEG, PNG, GIF and other popular formats or print the diagram out on multiple pages.

DTM Data Modeler is a CASE tool for database developers that supports both forward and reverse engineering. It is an easy-to-use tool allowing you to work both with logical and physical data models in the form of an entity-relationship (IDEF1X notation) diagram. The product is intended for database architects and developers and works with data sources via the ODBC, OLE DB, IDAPI or Oracle Call Interface, which means compatibility with all modern DBMS. Along with basic model properties (sets of entities and relationships between them), the program allows you to create indexes and triggers on the physical level corresponding to the tables of the database that is modeled. The foreign key migration feature makes schema development easier and more visual and also reduces the probability of errors in the integrity of the model. The program can create database schema objects directly in the database as well as to create SQL scripts corresponding to the model and taking into account the settings specified by the user.
The built-in scale and print tools of the model allow you to get a visual representation of the model in the hard copy form for presenting or discussing it. Powerful reverse-engineering tools make it considerably easier to work with existing databases and also provide easy migration from other tools. Both full and selective generation of model objects is available to the user, which makes the product more flexible.
