Topology Inference in Store, Code, and Forward Networks
This thesis presents a technique for active topology inference in store, code, and forward networks. Many techniques exist and are well suited for store-and-forward and cut-through switching. However, these simpler techniques ... -
Beyond Cryptography : A Multi-layer Approach to Communication Privacy
Recent developments in the field of physical-layer security are beginning to challenge commonly-held assumptions of how security can be obtained in a communication system. Conventional security practices almost always rely ... -
Cancer screening and detection using terahertz dielectric spectroscopy
The sensitivity of terahertz absorption to water, biological tissue structure content, and the degree of hydration of diseased tissues are exploited to distinguish between normal and malignant human skin tissues. This can ... -
Friendly Security Code-Based Image and Audio
The intent of our research is the development of the CAPTCHA system and improve the accessibility and usability of the CAPTCHA system. Accessibility is one of the two vital components of a CAPTCHA system. In the current ... -
A fast and scalable hardware architecture for K-means clustering for big data analysis
The exponential growth of complex, heterogeneous, dynamic, and unbounded data, generated by a variety of fields including health, genomics, physics, and climatology pose significant challenges in data processing and desired ... -
Patch antennas loaded with different resonator elements
