Resource exhaustion is one of the main challenges for the security of Wireless Sensor Networks (WSNs). The challenge can be addressed by using algorithms that are light weighted. In this paper use of light-weighted RContiguous Bit matching for attack detection in WSNs has been evaluated. Use of R-Contiguous bit matching in Negative Selection Algorithm (NSA) has improved the performance of anoma...

The recent increase in inequality in the U.S. and other developed countries has stimulated debate among economists. This debate is best exemplified by Thomas Piketty’s Capital in the twenty-first century and his critics. Taking aside the predictions for the future and the role that capital gains play in this debate, a deeper question is: what is a “normal” level of inequality in historical term...

BACKGROUND Dental anomalies are not an unusual finding in routine dental examination. The effect of dental anomalies can lead to functional, esthetic and occlusal problems. The Purpose of the study was to determine the prevalence and distribution of selected developmental dental anomalies in Saudi children. MATERIAL AND METHODS The study was based on clinical examination and Panoramic radiogr...

Numerous network anomaly detection techniques utilize traffic summaries (e.g., NetFlow records) to detect and diagnose attacks. In this paper we investigate the limits of such approaches, by introducing a technique by which compromised hosts can communicate without altering the behavior of the network as evidenced in summary records of many common types. Our technique builds on two key observat...

Combining Disparate Information for Machine Learning by Ko-Jen Hsiao Chair: Alfred O. Hero This thesis considers information fusion for four different types of machine learning problems: anomaly detection, information retrieval, collaborative filtering and structure learning for time series, and focuses on a common theme – the benefit to combining disparate information resulting in improved alg...

Modern cities are complex systems, evolving at a fast pace. Thus, many urban planning, political, and economic decisions require a deep and up-to-date understanding of the local context of urban neighborhoods. This study shows that the structure of openly available social media records, such as Twitter, offers a possibility for building a unique dynamic signature of urban neighborhood function,...
