A Detection Algorithm for Clipped OFDM Signals Using the IDFT-Matrix
A major drawback of the Orthogonal Frequency Division Multiplex (OFDM) principle is the high dynamic range of the transmit signal. The transmit Power Amplifier (PA) and other ele...

HeapMD: identifying heap-based bugs using anomaly detection
We present the design, implementation, and evaluation of HeapMD, a dynamic analysis tool that finds heap-based bugs using anomaly detection. HeapMD is based upon the observation ...

Detecting increases in feature coupling using regression tests
Repeated changes to a software system can introduce small weaknesses such as unplanned dependencies between different parts of the system. While such problems usually go undetecte...

Generalized Likelihood Ratio-based Face Detection and Extraction of Mouth Features
In this paper we describe a system to reliably localize the position of the speaker’s face and mouth in videophone sequences. A statistical scheme based on a subspace method is p...

Principled reasoning and practical applications of alert fusion in intrusion detection systems
It is generally believed that by combining several diverse intrusion detectors (i.e., forming an IDS ensemble), we may achieve better performance. However, there has been very lit...
