We propose a novel approach for head tracking, which combines particle filters with Isomap. The particle filter works on the low-dimensional embedding of training images. It indexes into the Isomap with its state variables to find the closest template for each particle. The most weighted particle approximates the location of head. We develop a synthetic video sequence to test our technique. The results we get show that the tracker tracks the head which changes position, poses and lighting conditions.

ARMask.The ARM has six operating modes: • User (unprivileged mode under which most tasks run) • FIQ (entered when a high priority (fast) interrupt is raised) • IRQ (entered when a low priority (normal) interrupt is raised) • Supervisor (entered on reset and when a Software Interrupt instruction is executed) • Abort (used to handle memory access violations) • Undef (used to handle undefined instructions) * ARM Architecture Version 4 adds a seventh mode: • System (privileged mode using the same registers as user mode)

The Linux Enterprise Cluster explains how to take a number of inexpensive computers with limited resources, place them on a normal computer network, and install free software so that the computers act together like one powerful server. This makes it possible to build a very inexpensive and reliable business system for a small business or a large corporation. The book includes information on how to build a high-availability server pair using the Heartbeat package, how to use the Linux Virtual Server load balancing software, how to configure a reliable printing system in a Linux cluster environment, and how to build a job scheduling system in Linux with no single point of failure. The book also includes information on high availability techniques that can be used with or without a cluster, making it helpful for System Administrators even if they are not building a cluster. Anyone interested in deploying Linux in an environment where low cost computer reliability is important will find this book useful.

DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.

This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).

Scotia Airlines is a new budget airline operating between Glasgow Airport and the Western Isles. It operates two 24-seater light passenger aircraft and requires a flight booking system. Because Scotia offers low cost air travel, there is a need to treat each flight as single cost centre and to be able to ascertain, at any moment, the amount of the cash taken for that flight. Reservations and bookings cannot be made until the flight details have been finalised (flight number, departure and arrival airports). A seat on a flight is considered booked when payment as been received for it. When a reservation is confirmed (changed to booked), the passenger name is checked against the original reservation. A flight can be in any of the following states: Available for bookings Checking in Boarding Closed
