Encryption based ransomware operates by iterating through all files with specific extensions on the computer and mutating them into an unusable form. The mutation, in many cases, can only be reversed if the user pays the operator of the ransomware a fee to get their files back. K-12 school districts have fallen victim to rampant malware as a…

Educational technology organizations have developed ambassadorship programs and are actively seeking social media influencers to participate in ambassador program activities voluntarily, with no pay. The purpose of this quantitative study was to describe the perceived motivational needs of educators who apply and voluntarily participate in unpaid…

Mobile devices are rapidly becoming a very popular and convenient means of delivering and consuming learning content worldwide. The rise in popularity is due in part to the technological advancements that mobile devices have made in recent years, along with developments in the online learning platforms and spaces that support mobile learning.…

Sensor systems are becoming pervasive in many domains, and are recently being generalized by the Internet of Things (IoT). This wide deployment, however, presents significant security issues. We develop security techniques for sensor systems and IoT, addressing all security management phases. Prior to deployment, the nodes need to be hardened. We…

Universities and Higher Education Institutions spend large sums of money to maintain and build network infrastructures. Current research and discussions in this area revolve around providing large amounts of bandwidth to students who live in a residence hall. However, there is a lack of information showing what is being used to support research…

This dissertation addresses three separate questions in human capital and development economics. In the first chapter, I study how college admission concerns drive students' field choices in a field-specific college admission system. To study this question, I leverage a college admission policy reform in Ethiopia that sharply increased the…

With the advent of virtualization and Infrastructure-as-a-Service (IaaS), the broader scientific computing community is considering the use of clouds for their scientific computing needs. This is due to the relative scalability, ease of use, advanced user environment customization abilities, and the many novel computing paradigms available for…

The patient portal is an electronic repository of health information, including doctor's notes, laboratory test results, and diagnostic imaging reports. There are limited studies that explore how individuals make sense of their health information, and use that understanding to increase health literacy. Education leaders should consider the ways…

The speed and availability of Internet-capable devices, such as computers, smartphones, gaming consoles, TVs, and tablets have made it possible for our society to be connected, and stay connected to the Internet 24 hours a day. The Internet of Things (IoT) describes a new environment where common objects are uniquely identifiable and accessible…

This study analyzed the meta-data collected from a honeypot that was run by the Federal Bureau of Investigation for a period of 5 years. This analysis compared the use of existing industry methods and tools, such as Intrusion Detection System alerts, network traffic flow and system log traffic, within the Open Source Security Information Manager…

This dissertation investigates how the emergence of the Internet of Things and the embeddedness of sensors and networked connectivity onto things, physical spaces and biological bodies rearticulates embodied spaces, devises practices of self-making and forms of power in the governance of the self and society. (Abstract shortened by ProQuest.).…

The fast growth of global routing table size has been causing concerns that the Forwarding Information Base (FIB) will not be able to fit in existing routers' expensive line-card memory, and upgrades will lead to a higher cost for network operators and customers. FIB Aggregation, a technique that merges multiple FIB entries into one, is probably…

Video compression and communication has been an important field over the past decades and critical for many applications, e.g., video on demand, video-conferencing, and remote education. In many applications, providing low-delay and error-resilient video transmission and increasing the coding efficiency are two major challenges. Low-delay and…

Anomaly detection is a challenging problem that has been researched within a variety of application domains. In network intrusion detection, anomaly based techniques are particularly attractive because of their ability to identify previously unknown attacks without the need to be programmed with the specific signatures of every possible attack.…

As wireless cyber-physical systems (WCPS) are increasingly being deployed in mission-critical applications, it becomes imperative that we consider application QoS requirements in in-network processing (INP). In this dissertation, we explore the potentials of two INP methods, packet packing and network coding, on improving network performance while…
