This computer, rather than individual flight instruments instruments , can determine the calibrated airspeed , Mach number , altitude , and vertical speed indicator altitude trend from input data from sensors such as an aircraft s pitot static system , gyroscope s, GPS and accelerometer s. In some very high speed aircraft such as the Space Shuttle , equivalent airspeed is calculated instead of calibrated airspeed. Air data computers usually also have an input of total air temperature . This enables computation of static air temperature and true airspeed . In Airbus aircraft the air datacomputer is combined with attitude, heading and navigation sources in a single unit known as the Air Data Inertial Reference Unit ADIRU .

Unreferenced date May 2007 Computerdata logging is the process of recording events, with an automated computer program, in a certain scope in order to provide an audit trail that can be used to understand the activity of the system and to diagnose problems. Logs are essential to understand the activities of complex systems particularly in the case of applications with little user interaction such as Server computing server applications . It can also be useful to combine log file entries from multiple sources. This approach, in combination with statistical analysis, may yield correlations between seemingly unrelated events on different servers. Other solutions employ network wide querying and reporting. Examples Examples of physical systems which have logging subsystems include process control systems, and flight data recorder black box recorder s installed in aircraft. Many operating systems and multitudinous computer programs include some form of logging subsystem. In the simplest case, log messages are written to a log file. Most operating systems and software framework s also provide more sophisticated services for logging. One example is the syslog service described in RFC 3164 , which allows the filtering and recording of log messages to be performed by a separate dedicated subsystem, rather than placing the onus on each application to provide its own ad hoc logging system. Interpreting In many cases, logs are esoteric or too verbose and therefore hard to understand they need to be subjected to log analysis in order to make sense of them. This is often done using special log analysis software. Transaction log Main Transaction log Most Database s maintain some kind of transaction log . Unlike the logs described above, these logs are not mainly intended as an audit trail ... log.

Design work started in 1968 and was completed in June 1970, beating out a number of electromechanical systems that had also been designed for the F 14. The CADC consisted of an Analog to digital converter A to D converter , several quartz pressure sensors, and the MOS based Central processing unit CPU . Inputs to the system included the primary flight controls, a number of switches, static and dynamic air pressure for calculating stall points and aircraft speed and a temperature gauge. The outputs controlled the primary flight controls, wing sweep, the F 14 s leading edge glove , and the flaps. The MP944 contained six chips used to build the CADC s CPU, all based on a 20 bit fixed point fraction two s complement number system. They were the Parallel Multiplier Unit PMU , the Parallel Divider Unit PDU , the Random Access Storage RAS , the Read only memory Read Only Memory ROM , the Special Logic Function SLF , and the Steering Logic Unit SLU .

In mathematics , computer science and graph theory , a distance matrix is a matrix mathematics matrix two dimensional array containing the distance s, taken pairwise, of a set of points. This matrix will have a size of N × N where N is the number of points, nodes or vertices often in a graph . Comparison with related matrices Comparison with Adjacency matrix Distance matrices are related to Adjacency matrix adjacency matrices , with the differences that a the latter only provides the information which vertices are connected but does not tell about costs or distances between the vertices and b an entry of a distance matrix is smaller if two elements are closer, while close connected vertices yield larger entries in an adjacency matrix. Comparison with Euclidean distance matrix Unlike an Euclidean distance matrix , the matrix does not need to be Symmetric matrix symmetric that is, the values x sub i,j sub do not necessarily equal x sub j,i sub . Similarly, the matrix values are not restricted to non negative Real number reals as they would be in the Euclidean distance matrix but rather can have negative values, zeros or imaginary number s depending on the cost metric and specific use. Although it is often the case, distance matrices are not restricted to being hollow matrix hollow that is, they can have non zero entries on the main diagonal.
