H.264/AVC is the current video standardization project of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The main goals of this standardization effort are to develop a simple and straightforward video coding design, with enhanced compression performance, and to provide a 鈥渘etwork-friendly鈥?video representation which addresses 鈥渃onversational鈥?(video telephony) and 鈥渘on-conversational鈥?(storage, broadcast or streaming) applications.

This small utility helps to generate seven segment display codes for different I/O connections. For example, AVR/PIC Port A.0 -> D Segment Port A.1 -> B Segment .... Also it can generate Common Cathode or Common Anode table codes.. I Coded it long time ago. I Hope help someone. Thank you

A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.

This functions computes SARMA or multiplicative (p,q) x (P,Q) models for (p,q,P,Q) in (pvec x qvec x Pvec x Qvec) it returns the best according to AIC where AIC has been modified to account for fixed parameters x = input data pvec = vector of p s set pvec=[0] for no AR qvec = vector of q s set qvec=0[] for no MA Pvec = vector of P s Qvec = vector of Q s T period for multiplicative model

This material is not only up-to-date, it defines up-to-date. It is truly cutting-edge. As the only book on the subject, Rootkits will be of interest to any Windows security researcher or security programmer. It s detailed, well researched and the technical information is excellent. The level of technical detail, research, and time invested in developing relevant examples is impressive.

A fractal is generally "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,"[1] a property called self-similarity. The term was coined by Benoî t Mandelbrot in 1975 and was derived from the Latin fractus meaning "broken" or "fractured." A mathematical fractal is based on an equation that undergoes iteration, a form of feedback based on recursion.[2]
