Adaptive Partition Schedulers are a relatively new type of partition scheduler, pioneered with the most recent version of the QNX operating system. Adaptive Partitioning (or AP) allows the real-time system designer to request that a percentage of processing resources be reserved for a particular subsystem (group of threads and/or processes). The operating systems priority driven pre-emptive scheduler will behave in the same way that a non-AP system would until the system is overloaded (i.e. system-wide there is more computation to perform, than ....etc

To achieve a better Eb/N0 (bit energy to noise ratio) than todays Rake receiver, a better estimation of the radio channel is needed. This paper proposes to reach this goal with artificial neural networks, which are used for detecting all multipaths in a direct sequence spread spectrum signal.

The output of the adaptive neual net is an estimation of the channel response. To increase the Eb/N0 of direct sequence spread spectrum signals, Rake receivers consist of up to 6 demodulators, which demodulate the strongest few echoes of the signal. Th ....etc

Abstract : A study with the goal of contributing to the development of adaptive phased array radar techniques is presented. Adaptive phased array radar is concerned with modification by closed loop control of the radar in response to a change of radar environment such that performance is improved with respect to performance before modification. This study has been concerned with selection of a quantitative measure of radar system performance and relating this measure of performance to control of phased array radar parameters. Modeling of the g ....etc

This seminar describes an approach to harvesting electrical energy from a mechanically excited piezoelectric element. A vibrating piezoelectric device differs from a typical electrical power source in that it has a capacitive rather than inductive source impedance, and may be driven by mechanical vibrations of varying amplitude.

An analytical expression for the optimal power flow from a rectified piezoelectric device is derived, and an ?energy harvesting ? circuit is proposed which can achieve this optimal power flow.

The harvesting cir ....etc

In many applications of speech processing the noise reveals some specific features. Although the noise could be quite broadband, there are a limited number of dominant frequencies, which carry the most of its energy. This fact implies the usage of narrow-band notch filters that must be adaptive in order to track the changes in noise characteristics. In present contribution, a method and a system for noise suppression are developed. The method uses adaptive notch filters based on second-order Gray-Markel lattice structure. The main advantages of ....etc

Definition
Space-Time Adaptive Processing (STAP) refers to a class of signal processing techniques used to process returns of an antenna array radar system. It enhances the ability of radars to detect targets that might otherwise be obscured by clutter or jamming.
. The output of STAP is a linear combination or weighted sum of the input signal samples .The adaptive in STAP refers to the fact that STAP weights are computed to reflect the actual noise, clutter and jamming environment in which the radar finds itself. The space in STAP refer ....etc

Adaptive active phased array radars are seen as the vehicle to address the current requirements for true ?multifunction? radars systems. Their ability to adapt to the enviournment and schedule their tasks in real time allows them to operate with performance levels well above those that can be achieved from the conventional radars.

Their ability to make effective use of all the available RF power and to minimize RF losses also makes them a good candidate for future very long range radars. The AAPAR can provide many benefit in meeting the pe ....etc
