New hardware algorithms and designs for Montgomery modular inverse computation in Galois Fields GF(p) and GF(2 [superscript n])

Creator:: Gutub, Adnan Abdul-Aziz
Abstract:: The computation of the inverse of a number in finite fields, namely Galois Fields GF(p) or GF(2ⁿ), is one of the most complex arithmetic operations in cryptographic applications. In this work, we investigate the GF(p) inversion and present several phases in the design of efficient hardware implementations to compute the...

The design of a test environment and its use in verification of a scalable modular multiplication and exponentiation

Creator:: Khair, Elias
Abstract:: Information security is an important concern in today’s communication and business world. To achieve these security functions, cryptography is utilized. RSA and the Diffie Hellman key exchange are some examples of cryptography algorithms that use modular multiplication to compute modular exponentiations. Modular multiplication requires division operations which becomes very time...

Investigating new design alternatives for a radix-2 modular multiplier kernal and I/O subsystem

Creator:: Chaitheerayanon, Akekalak
Abstract:: A main arithmetic operation for cryptographic systems is modular exponenti- ation. Exponentiation is computed by a long sequence of modular multiplications. Modular multiplication can be implemented in a general-purpose processor or a dedicated hardware, but dedicated hardware tends to be faster than a processor. Modular multiplication is a time-consuming operation,...

Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

Creator:: Ferreira, Andrew
Abstract:: The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...

Fatty acid profiling of soil microbial communities : a comparison of extraction methods and temporal dynamics in plant residue amended soils

Creator:: Fernandes, Marcelo Ferreira
Abstract:: A method based on fatty acid (FA) analysis is used to profile microbial community structure (MCS). Various extraction protocols are available, which alter the types of FAs extracted from soils. The more time consuming but widely used protocol extracts only FAs from phospholipids (PLFA). This technique is desirable because PLFAs...

Effects of selenium supplementation on plasma and milk of lactating women of habitually low selenium status

Creator:: Moore, Michelle L.
Abstract:: Twenty-one women, lifelong residents of Xichang County, Sichuan Province, China, an area of very low soil selenium (Se), received tablets containing either 100 μg Se daily as Se-enriched yeast (+Se) or no additional Se (-Se), throughout the last trimester of pregnancy and the first three months of lactation. Diet was...

Total Synthesis of Aspidosperma Alkaloids Leuconoxine, Melodinine E and Mersicarpine and Synthetic Studies directed toward the Iboga Alkaloid Ibogaine: Progress directed toward the dimeric Cephalotaxus Alkaloid Cephalancetine C

Creator:: Kim, GilSoo
Abstract:: The first part of this manuscript is about the total synthesis of the aspidosperma alkaloids leuconoxine, melodinine E and mersicarpine. Our synthetic strategy used a radical translocation-conjugate addition cascade to construct the core of the natural product. Specifically, a vinyl radical was generated from the homolysis of the C–I bond...

Multi-Criteria Risk Mapping Using Lean Tools for the Architecture, Engineering, and Construction Industry

Creator:: Viriato Maia Ferreira Pestana, Ana Catarina
Abstract:: Over the past two decades, the Lean Construction academic and practicing engineering community has used lean practices and tools to help improve the performance of the Architecture, Engineering, and Construction (AEC) industry. Lean practices have led to improved competitiveness of construction companies that have adopted them, by focusing on ways...

Dietary (n-3) and (n-6) fatty acids and vitamin E : their effects on the immune response of healthy geriatric Beagle dogs

Creator:: Tooley, Katie A.
Abstract:: We have previously shown that diets enriched with (n-3) fatty acids reduced the delayed-type hypersensitivity (DTH) skin reaction to keyhole limpet haemocyanin (KLH) in geriatric-Beagles. Although the amount of α-tocopheryl acetate in diets of the previous study exceeded requirements, plasma α-tocopherol concentration was significantly lower in dogs fed the high...

Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

Creator:: Matty, Ethan P.
Abstract:: This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...
