This paper presents a fast multi-stage method for on-line detection of RTP streams and codec identification of transmitted voice or video traffic. The method includes an RTP detector that filters packets based on specific values from UDP and RTP headers. When an RTP stream is successfully detected, codec identification is applied using codec feature sets. The paper shows advantages and limitati...

A source for errors in results of OLAP queries lies in neglecting changes in dimension data of Data Warehouses over time. In addition to the correct representation of such changes in temporal data warehouses it is necessary to discover such changes when they appear in the sources of a data warehouse. We propose to use data mining techniques in form of multidimensional outlier detection to disco...

This paper presents the preliminary results of an observational study into the use of novelty detection techniques for detecting physiological deterioration in vital-sign data acquired from Emergency Department (ED) patients. Such patients are typically in an acute condition with a significant chance of deteriorating during their stay in hospital. Existing methods for monitoring ED patients inv...

In this paper, the concept of multipurpose object detection system, recently introduced in [1], is discussed. Fig.1 below illustrates the innovative and the business aspects of this method: transform a classifier into an object detector/locator via an image grid. Classification techniques allow the application of powerful machine learning methods detailed below. A custom object detection system...

A novelty detection approach to condition monitoring of aerospace gas-turbine engines is presented, providing a consistent framework for onand off-line analysis, each with differing typical implementation constraints. On-line techniques are introduced for observing abnormality in engine behaviour during aircraft flights, and are shown to provide early warning of engine events in real-time. Off-...

For the purpose of automating a clinical diagnostic apparatus to quantify the deformability of human red blood cells, we present an automated image analysis procedure for on-line detection of the cell shape based upon the method of parametric deformable templates.

Nowadays, malicious URLs are the common threat to the businesses, social networks, net-banking etc. Existing approaches have focused on binary detection i.e. either the URL is malicious or benign. Very few literature is found which focused on the detection of malicious URLs and their attack types. Hence, it becomes necessary to know the attack type and adopt an effective countermeasure. This pa...
