Characteristics of semi-insulating GaAs photoconductive detectors under steady state illumination

Creator:: Yang, Howard C.
Abstract:: The optical and electrical characteristics of semi-insulating GaAs photoconductive detectors made with ohmic and Schottky contacts are studied in this thesis. Current - voltage measurements are made both in the dark and under varying power levels of HeNe laser (6328 Å) illumination. DC photocurrent gain is then calculated as a...

Ultrafiltration Membrane Fouling in Side-stream Aerobic Granular Sludge Membrane Bioreactor

Creator:: Yang, Zhengjian
Abstract:: The integration of low-pressure membrane filtration and aerobic granular sludge (AGS) reactor leads to a novel environmental biotechnological process with strong potential to overcome membrane fouling and demonstrate excellent wastewater treatment performance. However, membrane fouling mechanisms in the AGS based membrane bioreactor (MBR) are lack of systematic elaboration. In the...

Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

Creator:: Yang, Ping
Abstract:: Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

Use of the equilibrium contact angle as an index of contact surface cleanliness

Creator:: Yang, Jianguo
Abstract:: Advancing contact angles formed by water and aqueous ethanol solutions were measured on both bare surfaces and film-covered surfaces of acrylic, glass, hydrophilic and hydrophobic silicon, polycarbonate, polyester, and stainless steel. Each bare surface was initially characterized with respect to its hydrophilic - hydrophobic balance. Both protein films and milk...

Additive Manufacturing of Austenitic Oxide Dispersion Strengthened Alloy Using Powder Feedstock Gas-atomized with Elemental Yttrium via Laser Directed Energy Deposition

Creator:: Yang, Seongun
Abstract:: This study investigates the microstructure and mechanical properties of an austenitic Oxide Dispersion Strengthened (ODS) steel produced by the Laser Directed Energy Deposition (LDED) process using powder feedstock atomized with elemental yttrium. The Microstructure of the samples was characterized by electron microscopy, and mechanical properties were measured using a tensile...

Decoding channel coded higher-order QAM signals over Gaussian and Rayleigh fading channels

Creator:: Yang, Yun
Abstract:: In modern digital communication systems, error correction codes (ECC) are widely used and play an important role. The main effect of ECCs is to reduce the transmission error caused by channel noise, thereby protecting data and increasing the quality of information transmission. In addition, high spectral efficiency is desired in...

The review of PPP toll roads in the US and the simulation of the Chicago Skyway

Creator:: Xu, Wei
Abstract:: As the traffic demand increases at a faster rate than the upgrade and maintenance of transportation facilities through the traditional public financing methods in the United States, the Public-Private Partnership (PPP) is becoming an important supplement to the public transportation infrastructure investment. There are already several existing PPP toll road...
