The small satellite eld has become popular amongst academia, amateur satellite (AM- SAT) community, and commercial businesses due to the miniaturization of components and smaller form factors. Speci cally, the PocketQube ...
Scalable Approximate Dynamic Programming Models with Applications in Air Transportation

Balakrishna, Poornima (2009-09-28)

The research objective of the dissertation is to develop methods to address the curse of dimensionality in the field of approximate dynamic programming, to enhance the scalability of these methods to large-scale ...
Scalable Framework for Securing Constrained Edge Devices into an Information-Centric Network of Things

Clark, Nicholas Kent (2022)

This thesis provides a framework with associated implementation support, based on Information-Centric Networking (ICN), to address security, efficiency, and scalability challenges in the Internet of Things (IoT). IoT is ...
Scalable Methods for Modeling Dynamic Spatio-Temporal Data

Hsu, Yu-Lin

Hierarchical spatio-temporal models have been developed to model complex datasets exhibiting spatio-temporal (ST) autocorrelation; however, many of these models are purely descriptive and do not explicitly model the ...
Scalable Role & Organization Based Access Control and Its Administration

Zhang, Zhixiong (2008-06-27)

In Role Based Access Control (RBAC), roles are typically created based on job functions inside an organization. Traditional RBAC does not scale up well for modeling security policies spanning multiple organizations. To ...
Scheduling Algorithms Optimizing Throughput and Energy for Networked Systems

Zhang, Zhi (2013-08-20)

Scheduling problems consider allocating limited resources under constraints among competing requests in order to fulfill their obligations. Practical resource management algorithms with provable performance guarantees are ...
Secure Broadcast for Vehicular Communications

Melaragno, Anthony

Intelligent transportation systems use radio beacons to broadcast infrastructure infor- mation that is used for safe navigation. Authenticity and Integrity of such messages are essential to ensure that recipients can ...
Secure Communications Based Train Control (CBTC) Operations

Hartong, Mark W. (2009-05-18)

Communications Based Train Control (CBTC) provides positive train separation, over speed protection, and protection for roadway workers. Current system designs do not include trust management systems to provide support ...
Secure Cooperative Data Access in Multi-Cloud Environment

Le, Meixing (2013)

In this dissertation, we discuss the problem of enabling cooperative query execution in a multi-cloud environment where the data is owned and managed by multiple enterprises. Each enterprise maintains its own relational ...
Secure Data Aggregation in Wireless Sensor Networks

Roy, Sankardas (2008-12-19)

Wireless sensor networks have proved to be useful in several applications, such as environment monitoring and perimeter surveillance. In a large sensor network, in-network data aggregation (i.e., combining partial results ...
Secure Hardware Implementations of Lightweight and Post-Quantum Cryptography; Trade-offs, Applicability, and Tools

Abubakr Abdulgadir (2021)

Lightweight authenticated ciphers are crucial in many resource-constrained applications,including online payment, edge computing, and the Internet of Things. However, the current standard AES-GCM is not adequate for many ...
Secure Intelligent Radio for Trains (SIRT)

Bandara, K R Damindra Savithri (2017)

Positive Train Control (PTC) is a radio-based control system designed to ensure safe navigation of trains. Safety objectives of PTC are to avoid train to train collisions, train derailments and ensure railroad worker safety. ...
Securing Light Weight Cryptographic Implementations on FPGAs Using Dual Rail with Pre-Charge Logic

Velegalati, Rajesh (2009-09-28)

Recent advances in Field Programmable Gate Array (FPGA) technology are bound to make FPGAs a popular platform for battery powered devices. Many applications of such devices are mission critical and require the use of ...
Securing The Hardware System Stack: Hardware to Software Layers

Dhavlle, Abhijitt (2022)

Computing systems have come a long way concerning speed, performance, optimization,and security. The state-of-the-art designs are deployed in the real world, targeting a variety of applications. The hardware security domain ...
Securing the Information Disclosure Process

Zhang, Lei (2010-11-01)

In the problem of information sharing, two goals must be met to fulfill the require ments of both information providers and information consumers. That is, the information providers have constraints of data security/privacy ...
Security and Complexity Analysis of LUT-based Obfuscation: A Comprehensive Study

Kolhe, Gaurav

Logic locking and Integrated Circuit (IC) camouflaging are the most prevalent protection schemes that significantly thwart security threats, such as Intellectual Property (IP) piracy, hardware Trojans, reverse engineering, ...
SECURITY AND INTELLIGENCE MEASURE IN ONLINE MACHINE LEARNING-BASED DYNAMIC SPECTRUM SHARING NETWORKS

Monireh Dabaghchian (2019)

Cognitive radio (CR) is considered as a key enabling technology for dynamic spectrum access to improve spectrum eciency. This dissertation studies the two aspects of spectrum sharing networks: Security and intelligence ...
Security Through Frequency Diversity in The 5G NR Standard

Weitz, Joshua D

This thesis explores the use of pseudo-random frequency hopping for added security in the 5G New Radio specification. Frequency hopping makes it more difficult for an attacker to intercept, detect, or jam a wireless ...
Segmentation-free Approach to the Classification of the Strain of the Carotid Plaque from Ultrasound Images

Victoire, Marina

Carotid atherosclerosis is an arterial disease caused by the accumulation of plaque inside the walls of the carotid artery, a major artery that carries oxygen-rich blood from the heart to the brain. The buildup of plaque ...
A Semi-supervised Machine Learning Approach for Acoustic Monitoring of Robotic Manufacturing Facilities

Bynum, Jeffrey

Diagnosing characteristic industrial equipment characteristic behavior non-invasively and in situ is an emerging field of study. An algorithm was developed to acoustically monitor mechanical systems with minimal data ...
