This is a listing of both PhD and Master's· theses relating to the areas of forestry issued during the period from July 1976 to June 1981. The
list is arranged first by state, then by college or university within each state. Authors of theses are arranged alphabetically under each of...
As the functionality of digital chips continues to increase dramatically, chip- to-chip communication bandwidths must scale accordingly to avoid constraining the overall system performance. Therefore, high speed transceiver design has be- come an important research topic. In particular, the performance of the circuits that are responsible for timing accuracy are...
Scaling of CMOS technology has progressed relentlessly for the past several
decades. In order for this unprecedented scaling to benefit the performance of
large digital systems, the communication bandwidth between integrated circuits
(ICs) must scale accordingly. However, interconnect technology does not scale as
aggressively, making communication between chips the major...
The continued scaling of deep-submicron CMOS technology enables low-voltage high-frequency phase-locked loops (PLLs) to be fully integrated in complex mixed-signal systems. However, fluctuations due to the manufacturing process and variations in
environmental conditions, such as supply voltage and temperature, are also significantly increased. As a result, the performance of PLLs...
To realize pipelined ADCs in deep-submicron processes, low voltage techniques
must be developed to work around problems created by limited supply voltages such as
the floating switch dead zone, reduced SNR, and reduced OpAmp performance.
This thesis analyzes standard and low voltage design issues for pipelined ADCs
and proposes a...
Aerobic organisms have evolved many sensory mechanisms that allow
response to oxidants in the environment. One area of interest is the relationship
between the activity of the tumor suppressor protein p53 and the redox state of
thioredoxin. Human p53 activity is severely compromised in budding yeast lacking
thioredoxin reductase. Evidence...
Nitrosomonas europaea (ATCC19718) participates in the biological removal of nitrogen from wastewater by oxidizing ammonia to nitrite, the first step in nitrification. This bacterium is sensitive to heavy metals (Zn²⁺, Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide, compounds commonly encountered in wastewater treatment plants. Therefore, we characterized physiological and transcriptional responses...
The variegated aqueous chemistries of metal cations are applied to the design and synthesis of non-toxic solution precursors suitable for additive printing of large-area oxide electronics. Polycondensation behaviors of aqueous Al+3 and PO4 +3 are manipulated in the deposition of atomically smooth amorphous aluminum oxide phosphate (AlPO) dielectric films. AlPO...
The focus of this thesis is the investigation of thin-film transistors (TFTs) based on amorphous oxide semiconductors (AOSs) in two circuit applications. To date, circuits implemented with AOS-based TFTs have been primarily enhancement-enhancement inverters, ring oscillators based on these inverters operating at peak frequencies up to ~400 kHz, and two-transistor...
Amorphous oxide semiconductors (AOSs) are of great current interest for thin-film transistor (TFT) channel layer applications. In particular, indium gallium zinc oxide (IGZO) is under intense development for commercial applications because of its demonstrated high performance at low processing temperatures. The objective of the research presented in this thesis is...
