Active Noise Shaping Analog-to-Digital Data Converters

Creator:: Shi, Lukang
Abstract:: Successive-approximation-register (SAR) analog-to-digital converters are popular for medium accuracy, medium speed and low power applications, such as in biomedical applications. They have low latency and simple architecture compared with ΔΣ ADCs. This is because of SAR ADCs’ binary searching scheme. Furthermore, SAR ADCs can apply oversampling and noise shaping schemes...

Towards the Perfect Marriage Between Theory and Experiments in Drug Discovery and Synthesis : Insights into Structure Determination of Complex Natural Products and Mechanistic Understandings of Lactam Synthesis

Creator:: Snyder, Kevin M.
Abstract:: In this report, three studies are presented that aid in the development of drug discovery and their synthesis. In each, the importance of the marriage between computations and experiments is highlighted. Continued efforts in this vein are essential for future efforts towards improving human health. The first case study investigated...

Development of materials and devices for separation of polyamido[a]mine dendrimers

Creator:: Tennico, Yolanda H.
Abstract:: Over the last decade, the use of highly branched macromolecules, called dendrimers, is emerging. Polyamidoamine (PAMAM) dendrimers, in particular, have attracted high interest due to their unique properties, such as well-defined size, shape, and solubility in water. Our group, as part of an interdisciplinary team, is currently working on developing...

Opportunistic bandwidth sharing through reinforcement learning

Creator:: Venkatraman, Pavithra
Abstract:: The enormous success of wireless technology has recently led to an explosive demand for, and hence a shortage of, bandwidth resources. This expected shortage problem is reported to be primarily due to the inefficient, static nature of current spectrum allocation methods. As an initial step towards solving this shortage problem,...

A comparative study between sinusoidal and squarewave clocking for alleviating the jitter limitation in multi-gigaHertz ADCs

Creator:: Kesharwani, Divya
Abstract:: Various applications like wireless UWB communication, fast data acquisition systems and digital storage oscilloscopes needs ADCs with instantaneous input signal bandwidth from 0.1-40 GigaHertz range with 6-10 bits of resolution -- a challenging task and an impressive goal to achieve. Flash ADCs have been conventionally employed to achieve these goals...

Discovery, Processing and Characterization of New Copper and Hafnium-based Metallic Glass Alloys

Creator:: Saini, Jaskaran S.
Abstract:: Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....

Exciton and Polariton Nature in Organic Crystals

Creator:: Van Schenck, Jonathan D. B.
Abstract:: Understanding the impact of inter-molecular orientation on the optical proper-ties of organic semiconductors is important for designing next-generation organic (opto)electronic and photonic devices. However, fundamental aspects of how various features of molecular packing in crystalline systems determine the nature and dynamics of excitons have been a subject of debate. Toward...

Dynamics and Design of Green Fluorescent Protein-Inspired Superphotoacids and Red-Emitting Fluorophores with Transient Absorption and Femtosecond Stimulated Raman Spectroscopy

Creator:: Chen, Cheng
Abstract:: In the past decades, femtosecond stimulated Raman spectroscopy (FSRS) has been gaining tremendous popularity in fundamental sciences stemming from chemistry to biology. It is capable of capturing both equilibrium and non-equilibrium structural information across a broad range of timescales with simultaneously high temporal and spectral resolutions. Femtosecond transient absorption spectroscopy...

Surface Modification to Enhance Corrosion Resistance of Carbon Steels using Additive Manufacturing

Creator:: Murkute, Pratik V.
Abstract:: Low carbon steels (LCS) due to their high strength-to-cost ratio are one of the most ubiquitous materials used for a wide range of applications, including but not limited to automotive, construction, and transportation. However, the low corrosion resistance of LCS in neutral, acidic, or saline environments limits its utilization and...

Advancing Renewable Gas Storage using Flat-histogram Methods

Creator:: Pommerenck, Jordan K.
Abstract:: This work introduces the novel flat-histogram Monte Carlo (MC) method stochastic approximation with a dynamic update factor (SAD) and explores the convergence properties of a variety of related weight-based MC methods. The new method is applied to a number of physical `test’ systems including the 2D Ising model, a square-well...
