Time Delay Estimation in Room Acoustic Environments: An Overview

Time delay estimation has been a research topic of significant practical importance in many fields (radar, sonar, seismology, geophysics, ultrasonics, hands-free communications, etc.). It is a first stage that feeds into subsequent processing blocks for identifying, localizing, and tracking radiating sources. This area has made remarkable advances in the past few decades, and is continuing to p...

Use of GPUs in room acoustic modeling and auralization

All room acoustic modeling techniques are computationally demanding due to the underlying complexity of sound propagation. Traditionally, all the modeling methods have been implemented for the central processing unit (CPU) of the computer. Recent trends in terms of programmable many-core processors or graphics processing units (GPU) is resulting in a paradigm shift. Modern GPUs are massively pa...

Acoustic Noise Identification Using Fuzzy Modeling Techniques

This paper presents a new approach to acoustic noise identification, by introducing fuzzy modeling techniques. Fuzzy identification is compared to conventional linear identification techniques, using as the system to model a new device called ElectroMechanical Film (EMF), developed by VTT [1]. This device can be used either as an acoustic sensor or actuator. The obtained model represents the be...

Overview of Intrusion Detection Techniques in Database

Data is one of the most valuable assets in today's world and is used in the everyday life of every person and organization. This data stores in a database in order to restore and maintain its efficiently. Since there is a database that can be exploited by SQL injection attacks, internal threats, and unknown threats, there are always concerns about the loss or alteration of data by unauthorized ...
