MICROSTRUCTURE STUDY ON THE La0.7Sr0.3MnO3 AND RARE-EARTH OXIDE VERTICALLY ALIGNED NANOCOMPOSITE THIN FILMS
Two-phase (La0.7Sr0.3MnO3)0.5:(CeO2)0.5 (LSMO:CeO2) heteroepitaxial nanocomposite films were grown on SrTiO3 (STO) (001) by pulsed laser deposition. XRD and TEM results show that LSMO:CeO2 films epitaxially grow on STO as self-assembled vertically aligned nanocomposites (VAN). Magnetic and magnetotransport measurements demonstrate that the LSMO phases in the VAN structure behave differently from its epitaxial single phase counterpart. The greatly enhanced coercivity (HC) and low field magnetoresistance (LFMR) in VAN system is attributed to the strong interaction between the pervoskite the secondary phase. Our results suggest that growth of functional oxide in another oxide matrix with vertical heteroepitaxial form is a promising approach to achieve new functionality which may not be obtained in the single epitaxial phase
A digital computer program for studying elasto-plastic structural behavior due to cyclic loading
A computer program has been developed to study the behavior of plane stress structures under cyclic loading. Such phenomena as thermal ratcheting, alternate plasticity, shake-down and the Bauschinger effect may be considered. The incremental theory of plasticity has been used. The program deals with realistic conditions such as nonlinear strain hardening, nonlinear temperature distribution and occurrence of both compressive and tensile plastic flow. The concept of an average material property has been used. Thermal ratcheting of a beam subjected to a constant bending moment and a temperature cycle has been studied in detail. The analysis shows analytically that the rate of plastic strain growth reduces with an increase in the number of loading cycles. Applications of the computer program have been discussed. Further, the thermal ratcheting of a two bar model has been discussed considering the simplifying assumptions of linear strain hardening and the absence of compressive plastic flow --Abstract, page ii

Information Design for Plant Management to Predict Equipment Failure (Semester Unknown) IPRO 303: Information Design for Plant Management to Predict Equipment Failure IPRO 303 Final ReportSp08
IPRO 303 is working on the user interface for SmartSignal Corporation’s software which predicts equipment failures in coal fired power plants. We are now in the third stage of the project. We are to deliver the user interface of the software based on the studies done by two previous semesters. SmartSignal suggested that we also consider specific elements of the software such as the clear presentation of developing fault information, and the efficient communication system between users. An appropriate UI will utilize SmartSignal’s predictive analysis software to provide an efficient and clear means for power plant personnel to: · Predict or identify equipment faults · Understand the predicted faults · Prioritize the disposition of the predicted faults or highlight urgent or important faults · Reduce the need for plant personnel to have many years of experience or “institutional knowledge” The ultimate goal of this project is to introduce an innovative approach to the user interface which SmartSignal can use for predicting equipment failures in coal fire power plants. To realize this, we set these objectives. · Research and collect information relative to the User Interfaces [UI] from the first hand users of the software while examining the study done by the previous IPRO303. · Create the Requirements Document for the UI in light of the concerns expressed by SmartSignal and the results of research. · Generate several possible UIs based upon the Requirements Document stated above. · Select one of the Several UI for development of details and revise it based upon the input from SmartSignal. · Add details and finalize the design of the selected UI.Sponsorship: SmartSignalDeliverable

Design a System to Recycle Condensate from Residential Air Conditioners (Semester Unknown) IPRO 348: DesignASystemToRecycleCondensateFromResidentialAirConditionersIPRO348EthicsSu09
The goal of IPRO 348 is to first find a use for the condensate produced by air conditioners, and then to create a product that will recycle the condensate for said use. The first task for IPRO 348 is to collect information on how condensate is formed, its purity, and the amount that is produced by a central air conditioning system. The end goal of the IPRO is to have a marketable system that will collect and store the condensate produced by the air conditioning units and will then proceed to use the condensate in the form of cleaning water, irrigation water, and possibly various plumbing purposes such as flushing toilets. After creating a viable product, the IPRO team is determined to make the product scalable, expanding its market from residential to commercial industries. To fulfill this goal, the IPRO team has been broken down into subgroups which are each responsible for a different objective. The first subgroup is responsible for the creation of a device that will allow for the condensate to be collected and stored. The second subgroup is responsible for analyzing the collected sample’s composition and checking for bacterial growth. The third subgroup is responsible for setting the parameters and methods for condensate collection. The fourth subgroup is responsible for obtaining the condensate samples from various sites, as well as collecting environmental data. The fifth subgroup is responsible for beginning the marketing aspects of the project. As a whole, the IPRO team will determine how the project should progress.Deliverable
