Redesign of SPAN 1B-N, PA S. R. 0095 Segment 0300 using ductile-hybrid fiber reinforced polymer reba
The deterioration of transportation facilities has become a major concern in todayâ s society due to their age and increased use. Many existing bridges require rehabilitation to their concrete bridge decks and even new bridges will require repair or replacement within fourteen years of construction. These conditions are the result of the use of steel reinforcement in the concrete, which despite its high strength, ductility, low cost, and availability, is highly susceptible to corrosion. The ne
Identification of image transformation models
The selection of the appropriate transformation for aligning two images is anestimation problem: the parameters of the transformation for aligning two imagesare estimated from data such as the location of corresponding points in twoimages. In many cases, however, the appropriate equations for aligning twoimages may not be known: more than one transformation model may be areasonable candidate. Identifying the true transformation is important because it willlead to a more accurate alignment. This
Adhesion of protective coating appliques on contaminated aluminum surfaces
The goal of this research was to develop an appliquÃ© system to protect an aluminum surface previously coated with a RTV silicone rubber. The appliquÃ© consisted of a poly (urethane) - based film coated with a suitable adhesive. Two adhesion problems were studied in this project: 1) adhesion to the contaminated aluminum surface, and 2) adhesion to the protective film of the appliquÃ©. Adhesion can occur according to several mechanisms: physical adsorption, chemical bonding, diffusion, elec
Contracting and Signaling, Winter 2008
Course prepares you to advise clients or your own organization on the design of contracts and screening policies when one of the parties has an information advantage over the other. For example, students study the design of patent licenses (the licensor knows more about the market), the design of social systems to reduce spam (the spam sender knows more about the content before the recipient decides whether to read), and the design of performance contracts for professional services (e.g., consul
Quantitative models for early prediction of software development success: a practitioner’s perspec
This study investigated some of the early non-technical components of the software development process from the perspective of project success. The causal relationships among these components, as well as their relationship to software practitionersâ overall perception of project success, were depicted through a Bayesian Belief Network. Components related to sponsor/management, customer/users and requirements management. Data was gathered through a survey of practitioners. This research is imp

Probabilistic approach for sensor fault detection and identification (A)
Operation performance of chemical, petrochemical and biochemical processes can be enhanced considerably by an integrated advisory system that is capable of performing simultaneous tasks of (1) instrument fault detection and identification and (2) process fault detection and diagnosis. Lack of such advisory system, at present, is due to the fact that one of the assumptions of normal process operation and functional sensors is always required in existing methods that perform tasks 1 and 2. This di
Effect of transverse load on fiber bragg grating measurements (The)
The field of communications has been revolutionized by the advent of optical fiber. Optical fiber now connects most of the world carrying a vast amount of information through a very limited physical medium. To the materials engineer, optical fiber technology has stimulated interest in a new type of micro-sensor application, where the size, weight, and the ability to integrate the sensor into a material structure play a major role. Areas of interest currently include materials characterization, c

Organic-inorganic hybrid mesoporous silica materials and their application as host matrix for protei
Transparent, organic-inorganic hybrid mesoporous silica materials have been prepared successfully via the acid-catalyzed hydrolysis and cocondensation of tetramethyl orthosilicate and various organosiloxanes via the nonsurfactant templated sol-gel process. The organic groups were attached to the silica matrix via the non-hydrolyzable Si-C covalent bond and functioned as network modifier. The synthetic conditions have been systematically studied and optimized. Nitrogen adsorption and transmission
Comprehension of emotion in neurodegenerative disorders
Recent evidence indicates that the posterior corpus callosum is smaller in patients with Alzheimer's disease (AD). Conversely, it has been demonstrated that patients with frontal systems deficits also have degradation of the anterior corpus callosum. Although these investigations indicate possible morphological relationships between the corpus callosum and cortical structures in neurodegenerative disorders, the relationship between specific neuropsychological measure of cognitive functioning and
Carbon nanotube reinforced carbon nano composite fibrils by electro-spinning
Fibers of Polyacrylonitrile (PAN) are the precursor of 90% of produced carbon fibers. It is generally thought that the better the degree of molecular orientation in the original PAN fiber, the better the mechanical properties, in particular the modulus of the resultant fibers. Electro-spinning is a unique process in that it is able to produce polymer fibers having diameters ranging over seve ral orders of magnitude, from the micrometer range typical of conventional fibers down to the nanometer r
