Design of LMI-based H/sup /spl infin// servo controller for cold tandem mill

This paper is study on the design of H/sup /spl infin// servo controller for a cold tandem mill, using LMI (linear matrix inequality)-based techniques. The controller improves the performance of AGC (automatic gauge control) system based on the Taylor linearized model of a cold tandem mill and satisfies robust stability, the restraint of disturbance and robust tracking property. The H/sup /spl infin// servo control problem is modified as an usual H/sup /spl infin// control problem, and the solvability condition of H/sup /spl infin// servo control problem depends on the solvability of modified H/sup /spl infin// control problem. But this modified problem does not satisfy standard assumptions for H/sup /spl infin// control problems, it can be solved by using LMI techniques. Consequently, the comparison of the performance between the authors' H/sup /spl infin// servo controller and the existing PID/FF (feedforward) controller shows the usefulness of this study.
Co-Optimization of Topology Design and Parameterized Control in a Traffic Network

In this paper, the authors introduce a co-optimization approach to jointly optimize the traffic network topology traffic controllers on the network. Since the network topology design has a long-term goal, while the traffic control is usually based on a minute-to-minute basis traffic situation, the authors uses a so-called parameterized traffic control method to bring them to the same time scale. They applied the proposed co-optimization approach in a simulation-based case study, and compared it with a pure topology design and an iterative optimization method. The results show that this method can improve the interaction between topology design and traffic control design, and result in a better overall performance.

It is important to understand how these factors interact with each other to improve or inhibit performance. This empirical research presents a framework for finding the fundamental relations between these factors. It proposes strategies for implementing knowledge creation initiatives. The framework mainly focuses on the “what factor” with respect to people and identifies the vital characteristics for the knowledge creation process. It mainly illustrates the parameters of knowledge transfer, which supports knowledge creation, thereby improving organizational performance.
Wax Lake Outlet control structure, Louisiana : hydraulic model investigation

Abstract : The Wax Lake Outlet Channel is an artificial channel that diverts 30 percent of the flow from the Atchafalaya River to the Gulf of Mexico. Because of degradation of the channel, its capacity to carry flow during nonflood periods has increased, resulting in lower river stages at Morgan City, Louisiana. A stone control structure was proposed to control the amount of flow passing through the Wax Lake Outlet Channel. Tests were conducted on a 1:30-scale model that initially reproduced one-half of the rock weir notch (425 ft) and a 785-ft- long portion of the overflow rock weir at elevation 7.5 ft referred to the National Geodetic Vertical Datum. The main objectives of this model were to determine a riprap gradation that would be suitable for anticipated flows, define low characteristics through the structure, and determine discharge coefficients for the proposed control structure. Discharge coefficients were obtained for free-flow and submerged-flow conditions for both the overflow weir and notch. Riprap stability test in the notch indicated that type C riprap (D sub 50 minimum = 2.31 ft) would remain suitable on the downstream slope if the slope was changed from a IV on 4H to 1V on 10H. Riprap stability tests for the overflow section indicated that a type B (D sub 50 minimum = 2.05 ft) gradation would remain stable for anticipated flows.

The evolution of the American academic library building

As a consultant on the design of academic library buildings, David Kaser often wondered why certain libraries were designed as they were. Finding the answer to this question led him to visit over 600 libraries throughout the world, and to assemble information on over 1,500 structures. The results of his wide-ranging search are documented in this comprehensive book, which traces the architectural history of American academic libraries from the 1800s to the present. For selected buildings-those which the author considered typical of a specific era or environment-detailed information is provided, including a wealth of photographs, diagrams and charts. Other buildings are listed in the comprehensive appendix included in the book, along with their location and the date the library was first opened. From the ante-bellum buildings of the 1840s, to the modular buildings of the 1990s, The Evolution of the American Academic Library Building provides an interesting overview of the relationship between function and design-as well as librarian and architect-in the academic library.
A Comparison of Motion-Sensing Game Technologies for use in Physical Rehabilitation

In this thesis we evaluate the use of Wii, Kinect and Move for use in physical rehabilitation. The goal of this thesis is to evaluate the feasibility of these low-cost commercially available motion-sensing devices for rehabilitation and to explore what strengths, weaknesses and challenges exist in that use. This is guided by two perspectives, the technical feasibility and the feasibility as viewed by physical therapists, on this basis we construct some high level guidelines for the implementation of games for physical rehabilitation. This thesis uses the interpretive approach and qualitative methods, this is instantiated with the use of Research Through Design. Some qualitative methods applied were a focus group, interviews, questionnaire and prototyping. The prototype artifacts are used to provide concrete embodiments of theory and technical opportunities, these artifacts also serve as a conduit for transfer of the research. The prototypes are used to evaluate the technical feasibility of the Wii, Kinect and Move based upon specified requirements in physical rehabilitation. The author presents a set of high level quality attributes for evaluating the capabilities of the various sensors and libraries in the context of two games developed for physical rehabilitation. The Wii, Kinect and Move all have different strengths and weaknesses for the usage scenarios specified. Next, the prototypes are used as starting point for evaluation by the expert panel in a focus group, the focus group consisted of three physiotherapists. The physiotherapists found the motion-sensing technology very promising but could not determine on a general basis which device is the most suitable since each patient have very different individual requirements to his therapy depending on the level of injury. The experts also stated some of the most promising areas of this augmented rehabilitation was the motivational, social and tactile facets. The experts found some of the typical commercial games to be too focused on the fun aspect, lacking in concise direction of exercises, and, lacks the needed adjust-ability to the difficulty. Based upon the technical evaluation and the expert panels feedback, the author suggest a list of guidelines for aiding construction of serious games for rehabilitation.
A new SC differentiator for two-path bandpass /spl Delta//spl Sigma/ modulator design

A new architecture of a fully differential switched capacitor (SC) differentiator is proposed as the building block of two-path bandpass SC /spl Delta//spl Sigma/ modulators. Compared to other SC differentiators, the pole in its transfer function is not sensitive to capacitor mismatches, and there is less switch thermal noise in the new architecture. The opamp in the differentiator has a smaller capacitance load. Using the new SC differentiator, a fully differential fourth-order two-path SC bandpass /spl Delta//spl Sigma/ modulator was built. The signal narrowband of the modulator is 200 kHz centered at 15 MHz. The effective sampling frequency is 60 MHz, double the physical clock frequency. The test circuit was implemented in 0.35-/spl mu/m CMOS process. The measured signal-to-noise ratio is 77 dB. The power dissipation is 14.5 mW at a 3.0-V supply voltage.
Mechanical Properties of Flush-Riveted Joints

The strength of representative types of flush-riveted joints has been determined by testing 865 single-shearing, double-shearing, and tensile specimens representing 7 types of rivet and 18 types of joint. The results, presented in graphic form, show the stress at failure, type of failure, and d/t ratio. In general, dimpled joints were appreciably stronger than countersunk or protruding-head joints, but their strength was greatly influenced by constructional details. The optimum d/t ratios have been determined for the several kinds of joints. Photomicrographs of each type show constructional details and, in several instances, cracks in the sheet.
Longitudinal study revealing motor, cognitive and behavioral decline in a transgenic minipig model of Huntington's disease

ABSTRACT Huntington's disease (HD) is an inherited devastating neurodegenerative disease with no known cure to date. Several therapeutic treatments for HD are in development, but their safety, tolerability and efficacy need to be tested before translation to bedside. The monogenetic nature of this disorder has enabled the generation of transgenic animal models carrying a mutant huntingtin (mHTT) gene causing HD. A large animal model reflecting disease progression in humans would be beneficial for testing the potential therapeutic approaches. Progression of the motor, cognitive and behavioral phenotype was monitored in transgenic Huntington's disease minipigs (TgHD) expressing the N-terminal part of human mHTT. New tests were established to investigate physical activity by telemetry, and to explore the stress-induced behavioral and cognitive changes in minipigs. The longitudinal study revealed significant differences between 6- to 8-year-old TgHD animals and their wild-type (WT) controls in a majority of the tests. The telemetric study showed increased physical activity of 4.6- to 6.5-year-old TgHD boars compared to their WT counterparts during the lunch period as well as in the afternoon. Our phenotypic study indicates progression in adult TgHD minipigs and therefore this model could be suitable for longstanding preclinical studies of HD. This article has an associated First Person interview with the first author of the paper. Summary: The transgenic minipig model of Huntington's disease demonstrates a slow-progressing motor, cognitive and behavioral phenotype with later onset in adulthood.

Fabrication and Characterization of Cobalt-Pigmented Anodized Zinc for Photocatalytic Application

Population growth and urbanization have led to water scarcity and pollution, which is a health hazard not only to humans but also to the ecosystem in general. This has necessitated coming up with ways of treating water before consumption. Photocatalysis has proved to be one of the most promising cheap techniques that involve chemical utilization of solar energy. TiO2 widely used in photocatalysis absorbs a narrow range of the solar spectrum compared to ZnO. In this regard, this study aimed at preparing and optimizing cobalt-pigmented ZnO, which is applicable in photocatalytic water treatment. The objectives in this study were to fabricate zinc oxide (ZnO) thin films by anodization, pigment the fabricated films with varying cobalt concentrations, characterize the fabricated films optically, and investigate the cobalt-pigmented ZnO’s performance in the methylene blue degradation under UV light irradiation. Mirror-polished zinc plates were sonicated in ethanol and rinsed. Anodization was done at room temperature in 0.5 M oxalic acid at a constant voltage of 10 V for 60 min, and cobalt electrodeposited in the films. Post-deposition treatment was done at 250°C. Optical properties of the films were studied using a UV-VIS- NIR spectrophotometer in the solar range of 300–2500 nm. The photocatalytic activity of the fabricated films was studied in methylene blue solution degradation in the presence of UV light irradiation for 5 h. Cobalt pigmenting was observed to reduce reflectance and optical band gap from 3.34 to 3.10 eV indicating good photocatalytic properties. In this study, ZnO film pigmented with cobalt for 20 s was found to be the most photocatalytic with a rate constant of 0.0317 h−1 and hence had the optimum cobalt concentration for photocatalytic water treatment. This can be applied in small-scale water purification.
Improved Healing of Large, Osseous, Segmental Defects by Reverse Dynamization: Evaluation in a Sheep Model

Abstract : Although this is officially an annual report, the release of the funds was delayed until July 2014 because of the PI s transfer from Beth Israel Deaconess Medical Center to the Mayo Clinic. Activities since then have succeeded in obtaining ICACUC and ACURO approvals, which was the first task in the statement of work, months 0-3. We have also initiated work on the second task, months 3-6 in which the design of the adjustable stiffness fixators will be finalized and the manufacturing initiated. One such fixator has been tested on a cadaveric sheep tibia. In the unlocked, loose position, the axial stiffness of the tibia and fixator was 102 N/mm. In the locked, stiff position it was 218 N/mm. This result is better than expected and close to the target of a 2.5-fold increment suggested by our previous studies using rats. This aspect of the project is the present focus of attention, and additional cadaver legs will be tested in due course.
Curling dynamics of naturally curved surfaces : axisymmetric bio-membranes and elastic ribbons

Curling deformation of thin elastic surfaces appears in numerous natural and man-made structures where a spontaneous curvature is present. In this thesis, we couple theoretical approaches and macroscopic experiments on elastic ribbons to understand the dynamics of curling of opened bio-membranes, motivated by the need to better understand recent microscopic observations during egress of Malaria infected red blood cells (MIRBC) and bursting of artificial polymersomes.In a first part, we study theoretically pore stability and curling propagation of an initially opened spherical bio-membrane. We model geometrically curling deformation as the revolution of a decentered Archimedean spiral, leading to a prescribed toroidal wrapping of the membrane. In this configuration, we show how the stability of a pore to curling depends strongly on both line-tension and shear elasticity and we discuss these results in relation to the curling of MIRBCs membranes. Moreover, taking into account viscous dissipations, the consequent dynamics we calculate agrees quantitatively well with experimental data obtained during opening of MIRBCs. Our approach shows in particular how the membrane dissipation resulting from the surface redistribution dominates curling dynamics over outer viscous dissipation.However, the complexity of the spherical geometry and the lack of detailed images in microscopic observations hamper the development of more accurate models where the coupling between flow and deformation is fully understood. Subsequently, we study in a second part the curling deformation of macroscopic naturally curved elastic ribbons in different viscous media and elastic conditions. At high Reynolds numbers, due to the tendency of ribbons to localize bending deformations when a curling front travels down the material, we show that curling reaches rapidly a constant propagating velocity. In this regime, the ribbon wraps itself into a compact roll whose size is predicted through the solitary wave solution of the associated Elastica. At low Reynolds numbers, however, closer to the hydrodynamic conditions of curling in microscopic membranes, we show that the strong lubrication forces induce a non-compact curling. The overall size of the spiraling ribbon increases in time leading to a temporal decrease of the released elastic power and therefore a consequent decrease in velocity. We discuss how such discovery sheds a new light on the modeling of curling in MIRBCs and polymersomes.
Design Consideration of Fogging and Wet Compression Systems as Function of Gas Turbine Inlet Duct Configurations

Ambient temperature strongly influences gas turbine performance with power output dropping between 0.5 to 0.9 % for every 1 °C of temperature rise. This is accompanied by a significant increase in the heat rate, resulting in increased operating costs. As an increase in power demand often coincides with high ambient temperatures, power augmentation during the hot part of the day is of value to gas turbine operators. This is true for both the utility industry, where peak-rate power payments often apply, and to the petrochemical and process industries, where throughput can be improved or held constant as ambient conditions change. Evaporative fogging and wet compression are relatively low-cost solutions for recovering reduced gas turbine output.This paper addresses the important design considerations for fogging and wet compression systems for different sized gas turbines with different duct configurations. These design considerations include the selection of appropriate ambient psychrometric design conditions, selection of appropriate fog nozzles and the optimization of fog nozzle manifold locations in the inlet ducts. For this research, Computational Fluid Dynamics (CFD) software is used to analyze the interaction between the atomized water droplets and the airflow within the confined geometry of inlet air ducts. The location of the nozzle manifolds is simulated in the inlet ducts for four different inlet duct configurations. Experimentally obtained spray data is used to simulated water atomization in the inlet ducts. The effect of the duct geometry is analyzed in term of fog-spray cooling efficiency based on both nozzle manifold location and droplet size distribution.Copyright © 2015 by ASME
Magnetic Sensor for Nondestructive Evaluation of Deteriorated Prestressing Strand--Phase II

This is a report describing the activities and accomplishments in this project, completed through November 30, 2009. The overall goal of this project is to investigate the feasibility of a magnetic sensor to detect in-situ corrosion of prestressing strand in prestressed concrete bridge beams. Corrosion is a slow developing phenomenon which is not adequately detected using sensors currently in service. Despite national studies, no effective nondestructive sensor technology has been identified for prestressing strand corrosion. An effective sensor for corrosion will be able to get a snapshot of the corrosion in time by sensing the corrosion by-products or a direct change in member properties due to corrosion. This is a departure from the typical procedure of measuring a quantity, such as strain, which is a secondary effect of corrosion. The need for the proposed sensor is particularly acute in Ohio where there are many prestressed box girder bridges. Experiments investigated the proposed method of magnetic detection for corrosion in prestressing strands. Two main clear findings are: 1) Magnetic detection can reliably distinguish cross sectional areas and 2) An improved electromagnet design would help in better and more practical detection. The first finding shows that development of a practical sensor can be undertaken with a reasonable prospect of success. The second finding shows that whether the remnant magnetism or the induced magnetic field method is used, it is necessary to achieve magnetic saturation of the samples at a higher level than what is possible with the small DC electromagnet used. A larger electromagnet which can reach a higher level of magnetic saturation and is designed for use with concrete will allow us to get an adequate signature of the remaining strand cross section. Achieving an effective magnetization through concrete requires an understanding of the magnetic properties of concrete and the magnetic fields for objects not in contact with the electromagnet. Based on the work to date, the fundamental difficulties that could be fatal to the sensor development are the need to magnetize the specimen from one side and the need to “see” through concrete. Access to a larger electromagnet designed specifically for this purpose can provide proof of concept resolution for these issues. In addition, the research team has been successful in an initial interaction with a large industrial electromagnet firm, Ohio Magnetics, Inc., to develop a commercial partnership. Overall, the work has highlighted the need for a stronger electromagnet, motivation to strengthen the theoretical basis and has given the team confidence that the core idea of magnetic detection of the prestressing strand area is sound. The design and procurement of an improved electromagnet through Ohio Magnetics has already begun and will be used in the next phase.
