PHO13 in Saccharomyces cerevisiae (budding yeast) is a para-nitrophenyl phosphatase (pNppase) of the haloacid dehalogenase (HAD) superfamily. A biological substrate for PHO13 had remained undiscovered while a knockout phenotype has only been observed in strains engineered to grow on D-xylose. The purified enzyme has... READ MORE
Elliptic curve cryptography (ECC) is an ideal choice for low-resource applications because it provides the same level of security with smaller key sizes than other existing public key encryption schemes. For low-resource applications, designing efficient functional units for elliptic curve computations over binary fields... READ MORE
Homomorphic Encryption has been considered the 'Holy Grail of Cryptography' since the discovery of secure public key cryptography in the 1970s. In 2009, a long-standing question about whether fully homomorphic encryption is theoretically plausible was affirmatively answered by Craig Gentry and his bootstrapping construction.... READ MORE
2-D Semiconductors are novel materials in the field of nano-electronics. Their unusual transport properties have led to an extensive research attention towards similar materials. Graphene has carriers that exhibit an effective "speed of light" (106 m/s) in the low energy range of This research proposes... READ MORE
In the music world, the oldest instrument is known as the singing voice that plays an important role in musical recordings. The singer's identity serves as a primary aid for people to organize, browse, and retrieve music recordings. In this thesis, we focus on... READ MORE
This thesis investigated the effect of an induction sealing process and time on the removal torque of continuous thread and child resistant plastic closures. An application torque of 19 in-lb was applied to the high density polyethylene (HDPE) bottle/closure systems. After passing the bottle/closures through... READ MORE
In the present research, 1-butyl-2,3-dimethyl-4-vinylimidazolium trifluoromethane sulfonate (triflate) was synthesized and polymerized. This is the first report of the synthesis and polymerization of this ionic liquid monomer. The resulting polymer was characterized by NMR, GPC and thermal analysis (DSC and TGA). The number average molecular... READ MORE
The objective of this thesis project is to synthesize 1,2-disubstituted cyclopropene compounds from internal alkynes and diazoacetate compounds via (2÷1] cycloaddition reactions catalyzed by rhodium acetate (Rh2(OAc)4). To date, there is no known synthetic transformation to achieve this substitution pattern. 1,2-disubstituted cyclopropene compounds are versatile... READ MORE
The goal of this study was to identify BPD markers by gene expression profiling in lung and peripheral blood mononuclear cell (PBMC) gene expression data. Studies of BPD are often focused on lung tissue, but rarely venture to find markers of the disease... READ MORE
Nucleosome positioning is critical for gene expression and of major biological interest. The high cost of experimental mapping of nucleosomal arrangements signifies the need for computational approaches to predict nucleosome positioning at high resolution. Here, we present a web-based application to fulfill this need by... READ MORE
This thesis will evaluate the possibility of eliminating EPS from the cold chain packaging system by replacing it with Vacuum Insulated Panels in Greenbox to create a sustainable and reusable packaging system. The most widely used packaging materials in the cold chain system have been compared... READ MORE
On secure networks, even sophisticated cyber hackers must perform multiple steps to implement attacks on sensitive data and critical servers hidden behind layers of firewalls. Therefore, there is a need to study these attacks at a higher multi-stage level. Traditional taxonomy of... READ MORE
As interest in online coupons from distributors like Groupon and Living Social have grown, eBay has proposed and built a marketplace. This marketplace is called eBay Local. It is a place where local merchants can post coupons that distributors can bid on the right to... READ MORE
Whether realized or potential there are a multitude of goals that the environmental manager may be working toward achieving. This thesis evaluated the hypothesis that regardless of the operational goal(s) that the environmental manager may be working toward, the ultimate goal is to achieve... READ MORE
Sign language synthesis is a useful tool in addressing many of the issues faced by deaf communities. Sign languages are as different from spoken languages as spoken languages are from each other, and hence deaf persons raised learning sign language are not automatically proficient... READ MORE
We first study systems of N Schwarzschild black holes in a time-symmetric spacelike hypersurface with axial symmetry. Apparent horizons are found by numerically solving a non linear system of 3 coupled ODE's using Mathematica. The location of the apparent horizon is calculated in each system... READ MORE
