Dynamic aspects of adsorbed polymer layers: Evidence of glass-like transitions
… The weakly adsorbing molecules in these experiments were protio and deuterio polystyrene (hPS & dPS), and polydimethylsiloxane (PDMS) in control experiments. The more strongly adsorbing molecules in these experiments were protio and deuterio poly(methyl methacrylate) (hPMMA & dPMMA), and …

Non-traditional catalysis by plasmonic nanostructures
… the field remains plagued by insufficient control experiments and frequent misattribution of catalytic activity. This dissertation seeks to explore nanoscale catalysis carefully and to emphasize the need for careful control experiments, systematic benchmarking, and a clear understanding of …

Using affinity purification -- mass spectrometry to identify aryl hydrocarbon receptor nuclear translocator interacting proteins
… <p>column bounded with 6x HIS-ARNT. Two negative control experiments were done. The first one by the application of the liver extract only on non-ARNT bound column. The second one by the application of 100 mg of bovine serum albumin on 6x HIS-ARNT bound column. The mouse liver extract was applied …

Design of, and initial experiments with, a MIMO plate control testbed
This work discusses the design of, and initial experiments with, a MIMO plate control testbed. This structure will be used as a development and standard comparison site for AVC and ASAC and is an extension of previous SIMO control investigations which used accelerometers and shakers. This portion …

Multi-vehicle rover testbed using a new indoor positioning sensor
… are then used in high-level path planning and control algorithms. Single and multi-rover tests are performed using single and multi-waypoint path plans. The results from these tests demonstrate the correctness of the system model, estimator, and control algorithms. This testbed serves as a …

A low cost modular actuator for dynamic robots
This thesis details the hardware and control development for a low-cost modular actuator, intended for use in highly dynamic robots. A small 12 degree of freedom quadruped robot has built using these actuators, on which several control experiments have been performed. Despite the relatively low …

The application of colloidal photocatalysis in actinide photoredox chemistry
… to efficient photocatalytic metal ion valence control. Nuclear reprocessing streams typically have pFls of 1 or less. Thus, the photocatalyst employed must be both stable toward acid dissolution at low p1-I and be possessed of charge carrier thermodynamics which may be exploited in actinide …

1. The Endocyclic Restriction Test: Oxygen Transfer From N-Sulfonyl Oxaziridines to Alkenes and Fluorine From N-Fluorosultams to Carbanions. 2. Intra- and Intermolecular Kinetic Isotope Effects in Directed Lithiations
… constructed for the transfer of fluorine, the control experiments conducted indicate that this reaction is amenable to study using the endocyclic restriction test. The mechanism of hydrogen transfer from a benzylic or aryl carbon atom to organolithium reagents has been investigated by measuring …

Clock tree synthesis under aggressive buffer insertion
… more freedom and thus achieves more robust slew control. Buffer insertion along routing paths had been mostly avoided previously due to the difficulty of maintaining a low skew under such aggressive buffer insertion. We developed an accurate timing analysis engine for delay and slew estimations …

Design and construction of an autonomous ornithopter
… a host of new problems in vehicle dynamics and control to explore. In order to better study the control of flapping wing flight we have developed a large scale ornithopter called the Phoenix. It is capable of carrying a heavy (400 gram) computer and sensor package and is designed specially for …

Evaluation of a mitochondrial test for the determination of chemical toxicity
… parameters were measured and compared to control experiments. The toxicity of the chlorophenos, measured by the 50% uncoupling concentration (UC50), increased with increasing chloro substitution. The UC50 values for the five chlorophenols were compared to six physicochemical parameters for …

Characteristics of Active Combustion Control for Liquid-Fuel Systems with Proportional Primary Fuel Modulation
The first part of this work focuses on control experiments performed on an unstable kerosene-fueled turbulent combustor. Using a phase shift controller and primary fuel modulation stability is successfully gained for a wide band of global equivalence ratios allowing the limitations of the control …

Covalent coupling of growth factors to collagen matrices: a novel development towards a tissue substitute with enhanced angiogenesis
… coupling activity can then be compared with control experiments in which the VEGF was simply admixed. In order to prevent rapid degradation, collagen sponges used as protein drug delivery substrate were cross-linked by SS-PEG3400-SS. The biological behavior of collagen sponges as well as …
