Network model

The network model is a database model conceived as a flexible way of representing objects and their relationships. Its original inventor was Charles Bachman, and it was developed into a standard specification published in 1969 by the CODASYL Consortium. Where the hierarchical model structures data as a tree of records, with each record having one parent record and many children, the network model allows each record to have multiple parent and child records, forming a lattice structure.

Cerberus FTP Server

Cerberus FTP Server supports SSL and TLS encryption and a graphical user interface that can be hidden or accessed from the system tray. The server is able to listen for connections on multiple interfaces (Multi-homed PCs), integrate with the Windows NT user database or Active Directory, run as an NT service, resume failed transfers, and offers a graphical manager for controlling user access to files and file operations.

Cerberus FTP Server is "free for personal use and not-for-profit charitable organizations". Its main features are:

* Secure SSL/TLS Encryption
* Active Directory Integration
* Individual Virtual Directories
* Small installation size
* Low CPU and memory utilization
* IP Manager to control connection attempts
* Adherence to RFC959 and RFC1123
* RFC1579-Firewall - Friendly FTP
* Hidden server mode (Hides server window)
* Resumes failed file transfers
* HIPAA Compliant
* NT Service Support
* Logging support based on log4cxx
* Taskbar icon control and status indicator
* Connections limit and timeout controls
* Transfer and connection statistics
* IPv6 compatibility

Semi-empirical quantum chemistry methods

Semi-empirical quantum chemistry methods are based on the Hartree-Fock formalism, but make many approximations and obtain some parameters from empirical data. They are very important in computational chemistry for treating large molecules where the full Hartree-Fock method without the approximations is too expensive. The use of empirical parameters appears to allow some inclusion of electron correlation effects into the methods.

Within the framework of Hartree-Fock calculations, some pieces of information (such as two-elecron integrals) are sometimes approximated or completely omitted. In order to correct for this loss, semi-empirical methods are parametrized, that is their results are fitted by a set of parameters, normally in such a way as to produce results that best agree with experimental data, but sometimes to agree with ab initio results.

Terminal Radar Approach Control

A Terminal Radar Approach Control or FAA TRACON in the United States) is an Air Traffic Control facility usually located within the vicinity of a large airport. Typically, the TRACON controls aircraft within a 30-50 nautical mile (56 to 93 km) radius of the airport between the surface and 18,000 feet.

A TRACON is sometimes called Approach Control or Departure Control in radio transmissions. In The US Air Force it is known as RAPCON (Radar Approach Control), and in the US Navy as a "RATCF" (Radar Air Traffic Control Facility) In Canada, Approach Control may be called Arrival or Terminal.
