Aspects are program modules that include descriptions of key events (called joinpoints) and code segments (called advice) to be executed at those key events when the aspect is bound (woven) to an underlying system. The MAVEN tool verifies the correctness of an aspect relative to its specification, independently of any specific underlying system to which it may be woven, and also allows establis...

We propose an alternative method for measuring Ln which we suggest will make field testing of buildings easier and more attractive to do. Although field testing is essential for quality control during construction, and to demonstrate conformity with building code requirements, it has challenges which make it unpopular. In particular the tapping machine’s fixed power-output and hence Ln’s lack o...

To improve the overall performance, many of the modern advanced digital signal processors (DSPs) are equipped with on-chip multiple data memory banks which can be accessed in parallel in one instruction. In order to effectively exploit this architectural feature, the compiler must partition program variables between the memory banks appropriately – two parallel memory accesses always must take ...

In this paper, a novel approach for estimating signal parameters in strong clutter using chaos synchronization based on Support vector machine (SVM) is proposed. Assuming that the clutter process is chaotic, chaos synchronization is found to be able to extract the weak signal even when the signal is totally embedded inside the clutter spectrum. When the dynamics of the chaotic system is unknown...

Large-scale data centers leverage virtualization technology to achieve excellent resource utilization, scalability and high availability. Although virtualization technology has the advantages such as fault isolation, environmental isolation and security isolation, current virtualization techniques do not have effective performance isolation among virtual machines. The hidden resource competitio...

This article presents a new method facilitating interference reduction in the Wigner-Ville distribution, which is used for nonstationary signal analysis, for example in machine condition monitoring. The algorithm is based on multiple Smoothed Pseudo Wigner-Ville distributions: differently smoothed time-frequency planes are compared and, for every point, a cross-term free value is calculated on ...

Power control is a critical component in CDMA cellular systems. Power control combats the “near-fat” effect by adjusting the transmit power of each mobile. This technique reduces the multiple access interference and if the system capacity is within the set limits the, desired signalto-interference ratios (SIRS) are achieved at all base stations. Research in the power control field covers centra...

Distant-talking automatic speech recognition (ASR) represents an extremely challenging task. The major reason is that unwanted additive interference and reverberation are picked up by the microphones besides the desired signal. A hands-free human-machine interface should therefore comprise a powerful acoustic preprocessing unit in line with a robust ASR back-end. However, since perfect speech e...

The emerging machine learning technique called support vector machines is proposed as a method for performing nonlinear equalization in communication systems. The support vector machine has the advantage that a smaller number of parameters for the model can be identified in a manner that does not require the extent of prior information or heuristic assumptions that some previous techniques requ...
