Abstract: The ability of the signal processing techniques to predict earthquakes may help to reduce the catastrophic effect of the earthquake. The earth\'s electric field signal is one of the features that can be used to predict the earthquakes (EQs) by analyzing the changes in its characteristic prior the earthquake. The signal is extracted using extended Linear Predictive Coding (LPC). This approach is based on the projection of the excitation signal on the right eigenvectors impulse response of the LPC filter. The resulting projected value is weighted by corresponding singular value, leading to an approximate sum of exponentially damped sinusoids (EDS). The extracted vector is used as input of the prediction system in order to determine the location of the incoming earthquake. Support vector machines (SVMs) method is applied as classification technique. The basic idea of SVMs is mapping non-linear training data into higher-dimensional feature space through the kernel function. This paper pres

Abstract: Current databases use many different protocols to communicate with their clients. Applications running on that communication protocols have to implement support for each of them. In this paper, we propose an abstraction layer, that enables an application to be applicable to many database protocols, such as the database protocol TNS for Oracle database, TDS for Microsoft SQL Server, DRDA for IBM DB2, and so on, using only one abstract interface. On this layer, there will be various primary abstract functions that database protocol applications can customize or integrate them for their own particular purposes, such as SQL rewrite, analysis, timing, result set cache, direct generation of result sets, intrusion detection, etc. The aim of this paper is to develop and propose this abstraction layer. Finally we show some examples of applications utilizing the proposed abstraction layer, they are able not only to perform SQL rewrite and timing, but also support the database protocol TNS, TDS,
