In the last decade, a number of high profile medical device recalls have drawn attention to the regulatory approval process, particularly the streamlined process for devices considered “lower risk” known as the 510(k). Approval of medical devices through the 510(k) Process is not based... READ MORE
Website Fingerprinting (WF) enables an eavesdropper to discover what sites the user is visiting despite the use of a VPN or even the Tor anonymity system. Recent WF attacks on Tor have reached high enough accuracy (up to 98%) to prompt Tor to consider adopting... READ MORE
Each year, thousands of people die from heart disease and related illnesses due to the lack of available donor organs. Left ventricular assist devices (LVADs) aim to mitigate that occurrence, serving as a bridge-to-surgery option. While short term survival rates of LVAD patients near... READ MORE
Research in recent years has demonstrated that intra and inter-chip wireless interconnects are capable of establishing energy-efficient data communications within as well as between multiple chips. This thesis introduces a circuit level design of a source degenerated two stage common source low noise amplifier suitable... READ MORE
The energy consumed by a building can be divided into two types. Operational energy (use phase) and embodied energy (energy consumed during the production, construction and replacement of building components). Typically, overshadowed by operational energy, embodied energy has slowly increased for a variety of... READ MORE
III-V semiconductors make for highly efficient solar cells, but are expensive to manufacture. However, there are many mechanisms for improving III-V photovoltaics in order to make them more competitive with other photovoltaic (PV) technologies. One possible method is to design cells for high efficiency... READ MORE
The driving hypothesis of this thesis is that a quantitative approach linking business objectives of an organization with technological limitations of the physical product would enable industry to create more innovative products. The main goal of this research is to validate the applicability and... READ MORE
Development of 5G technology and Internet of Things (IoT) devices has resulted in higher bandwidth requirements leading to increased scarcity of wireless spectrum. Cognitive Radio Networks (CRNs) provide an efficient solution to this problem. In CRNs, multiple secondary users share the spectrum band that... READ MORE
L1-norm Principal-Component Analysis (L1-PCA) is known to attain remarkable resistance against faulty/corrupted points among the processed data. However, computing L1-PCA of “big data” with large number of measurements and/or dimensions may be computationally impractical. This work proposes new algorithmic solutions for incremental and adaptive L1-PCA.... READ MORE
Inventory management is a vital section of a supply chain system. In a hospital setting, where delivering high quality patient care is a prime concern, inventory management is often overlooked. With the ever increasing demand for products, it becomes challenging to manage inventory in... READ MORE
Humans quickly parse and categorize stimuli by combining perceptual information and previously learned knowledge. We are capable of learning new information quickly with only a few observations, and sometimes even a single observation. This one-shot learning (OSL) capability is still very difficult to realize...

Modern computing applications are becoming increasingly data-hungry and computationally expensive. This trend continues even as hardware performance constraints loom with the impending death of Moore's law. Hence, systems have become increasingly heterogeneous in the pursuits of improving performance and reducing power consumption. Such a... READ MORE
As a software application is developed and maintained, changes to the source code may cause unintentional slowdowns in functionality. These slowdowns are known as performance regressions. Projects which are concerned about performance oftentimes create performance regression tests, which can be run to detect performance... READ MORE
We demonstrate a multiple micro aerial vehicle (MAV) system capable of supporting autonomous exploration and navigation in unknown environments using only a sensor commonly found in low-cost, commercially available MAVs—a front-facing monocular camera. We adapt a popular open source monocular SLAM library, ORB-SLAM, to support... READ MORE
There is increasing global interest in the application of circular economy as a tool for enabling the decoupling of economic growth from environmental degradation. Despite this growing interest, there is a lack of in-depth insight about the quantified potential benefits that value-retention processes (VRPs)... READ MORE
With natural gas drilling on the rise (Penn State, 2012), there is a general lack of data on the emissions from the entire lifecycle of hydraulic fracturing. This research project is designed to study the health impacts of emissions from high volume hydraulic fracturing... READ MORE
