Vector quantization systems are usually based on digital implementation of the core operations. In this paper, video compression systems exploiting an analog implementation of vector quantization are presented. The main advantages of analog design are exploited, obtaining notable performances when compared to other solutions found in the literature. The circuit features a very modular, complete...

The growing number of unauthorized activities and various trends of networking technologies in telecommunication network have added heavy burdens to telecommunication performance management (PM) system. One-class-support vector machine (OCSVM) is introduced in this paper, to automatically detect network anomalies. Real telecommunication performance data are employed in this paper to investigate...

This paper presents two strong baselines for the BioNLP 2009 shared task on event extraction. First we re-implement a rulebased approach which allows us to explore the task and the effect of domainadapted parsing on it. We then replace the rule-based component with support vector machine classifiers and achieve performance near the state-of-the-art without using any external resources. The good...

In high dynamic conditions, using vector tracking loops instead of scalar tracking loops in GPS receivers is proved as an efficient method to compensate the performance. The Minimum Mean Squared Error detector as a multiuser detector is applied in the vector tracking loop for more reliability and efficiency. The Kalman filter does the two tasks of tracking and extracting the navigation data aft...

The identity of musical instruments is reflected in the acoustic attributes of musical notes played with them. Recently, it has been argued that these characteristics of musical identity (or timbre) can be best captured through an analysis that encompasses both time and frequency domains; with a focus on the modulations or changes in the signal in the spectrotemporal space. This representation ...

In this paper, we investigate unsupervised fast speaker adaptation based on eigenvoice to improve the performance of Korean connected digit recognition over the telephone channel. In addition, utterance verification is introduced into speaker adaptation to examine whether input utterance is appropriate to adaptation or not. Performance evaluation showed that the proposed method yielded performa...

In this paper, two vector control systems for investigating the performance of Static Synchronous Series Compensators (SSSC) in steady state conditions are presented that are based on famous d-q axis theory. The workability of proposed method to simplify the SSSC mathematical expressions is shown. The performance of SSSC with two different vector controllers, first based on d-q line current...

a highly efficient cloning vector was constructed for cloning pcr products by inserting an 80 bp dna fragment into pgem-5zf (+) vector. the xcm i digestion of this vector gave rise to a 3’ overhanging deoxythymidine offering the possibility of cloning pcr products with 3' adenosine overhang created by taq dna polymerase. furthermore, two ecor i sites were added to the construct for identificati...
