Show moreThis IPRO is designed to support the Department of Homeland Security national security initiatives as outlined by the United States Government. The goal is to design a project that supports homeland security compliance guidelines. For example, depending upon interests of the group, a software program could be developed containing a matrix of risk and preventive factors which could be used to assess how well an organization meets Homeland Security Guidelines. Items might involve public policy, computer technology, facilities, transportation, communications, EPA, security, water and air. The need to protect our facilities and people in the Chicago area given recent terrorist activities and the frequent, heightened state of alerts is critical. A well-defined homeland security project can help in contributing to the initiative of establishing homeland readiness. This hands-on project will afford students the opportunity to research an apply concepts of transportation, mechanical, electrical, power, economics, and especially computer technology and engineering to homeland security.

Show moreThe goal of this interprofessional project will be to develop a test-bed system for a new device targeted at ECE 100 Introduction to Engineering. It may also be useful for an upper-level course in Hardware/Software Design for Embedded Systems. This course is being developed in response to feedback from the Accreditation Board for Engineering and Technology (ABET) that students need a major meaningful design experience involving integrated hardware/software design. An important aspect of this design experience will be the use of open-ended design problems that integrate a micro-controller with some larger system. Ideally, the students in this course would design and build a complete hardware/software system. However, this is unfeasible due to the time constraints of the semester and the cost constraints of providing the necessary parts. Instead, we propose to give students in the class a number of test-bed systems that represent an "almost complete" hardware system that requires additional software and hardware design activities in order to fully complete a system.

Show morehere is a continuing need to provide information and motivational materials to high school students to interest them in engineering. These students would also benefit by learning about the various educational programs offered to help them meet their goals. Finally, information on the application process, especially the varying student aid packages from universities, government and industry would benefit high school students. There may be other services that would interest and benefit high school students that this project team could identify. There is also a wide variety of information already available to high school students and guidance counselors from individual universities as well as commercial and government organizations, associations and various publications that rank institutions. The sheer number of sources and volume of information about colleges and careers can be quite daunting to navigate. Everyone who has been through this process knows how frustrating and stressful it can be for students, parents and counselors in not having confidence that the best information was identified in a timely way to consider alternatives and make intelligent decisions. It is envisioned that this project would seek information from IIT engineering freshmen as well as high school students and counselors about current practices and trends in how the web and other resources are used in this process. Based on survey data, the project team will develop a web site or portal that can organize and provide information and services regarded as most valuable to high school students and counselors in their decision making process -- and do so in an integrated way, with appropriate planning and selection tools to support the process. It is envisioned that this could ultimately become part of a seamless service from the earliest consideration of career direction and college selection by high school students, through to specific career and employer selection by college students, and finally extending to support for alumni as they maintain their competitive edge in their professional practice. This project is a continuation of an IPRO project from the Spring 2001 semester.

Show moreABSTRACT The purpose of this study was to examine the existence and strength of relationships between students’ cognitive skills and mathematical problem-solving performance. Specifically, relationships between students’ verbal, spatial, and analytical skills and their problem-solving performance on items that require a verbal response, items that require a spatial response, and overall problem-solving performance were investigated. A review of the literature also revealed assumptions of close links between verbal and logical/analytical skills, resulting in a lack of assessment of these skills as separate constructs. This study therefore sought to measure each of the cognitive skills separately in order to clearly establish the existence and strength of any pair-wise relationships among the cognitive skills. Ninety-eight students from the fifth- through eighth-grades were administered assessments of verbal skills, spatial skills, and logical/analytical skills, as well as a problem-solving instrument that consisted of a verbal (PST-Verbal) subtest and a spatial (PST-Spatial) subtest. The results indicated statistically significant relationships between students’ cognitive skills and problemsolving performance on the PST-Verbal subtest, the PST-Spatial subtest, and overall problem-solving performance. Surprisingly stronger relationships were found, however, between spatial skills and PST-Verbal performance than between verbal skills and PSTVerbal performance, and stronger relationships were found between verbal skills and PST-Spatial performance than between spatial skills and PST-Spatial performance. Statistically significant pair-wise relationships were also found among the cognitive skills, with the strongest pair-wise relationship existing between verbal and analytical viii skills. The relationship between verbal and spatial skills, although not as strong as the one that exists between verbal and analytical skills, was also quite strong.

Show moreSmart grid adds intelligence and bidirectional communication capabilities to today’s power grid, enabling utilities to provide real-time-pricing (RTP) information to their customers via smart meters. This facilitates customer participation in demand response programs to reduce peak electricity demand. ZigBee, as a wireless technology characterized by low cost, power, data rate, and complexity, is ideal for smart grid applications. Unfortunately, almost all ZigBee channels overlap with Wireless Local Area Networks (WLAN) channels, resulting in severe performance degradation. In this dissertation, firstly, practical ZigBee deployment guidelines under WLAN interference are presented. “Safe Distance” and “Safe Offset Frequency” are identified by means of a comprehensive approach consisting of theoretical analysis, software simulation, and empirical measurement. In addition, a frequency-agility based interference avoidance algorithm is proposed and is implemented. The proposed algorithm detects interference and adaptively switches nodes to “safe” channels dynamically to avoid interference with low latency and energy overhead. Later we propose a real-time residential demand response scheme based on price information provided by ZigBee enabled smart meters. We model the price signal as a random process with known deterministic components, and formulate the problem of cost-minimization as a stochastic scheduling problem. A constraint on the total power consumption is considered to avoid peak shifting. An opportunistic scheduling algorithm consisting of two stages is proposed. Each user is tentatively scheduled based on the optimal stopping approach as if there is no power constraint at the first stage, while the power constraint is taken into account at the second stage. The proposed scheduling algorithm can be implemented in either a centralized or distributed fashion. Simulations validate proposed scheme can evidently reduce the cost of electricity users. At last, an optimal and automatic residential load scheduling scheme with distributed storage system based on our price prediction scheme is proposed. The price prediction scheme forecasts the future 24-hour prices according to day-ahead pricing and RTP history. Our designed scheme adopts integer programming computation to provide simple solution for customers to minimize the total cost including electricity expenditure and storage degradation while satisfying customer time requirement. The performance of proposed scheme is then evaluated through simulation.

Show morePredicting chain microstructure became an important task for polymer scientists. Polydisperse nature of polymer molecules makes it an interesting research area. In this work, a new method, called “Chain-by-Chain Monte Carlo Method” (CBCMC), is presented for simulating chain microstructures one-by-one or chain-by-chain. To the best of our knowledge, it is a new approach for the simulation of chain microstructures. It is a hybrid deterministic-stochastic method that uses the best of two worlds by obtaining information on the mean-field background environment as concentrations of polymer populations and small molecules (only) from the deterministic solver and using it in the stochastic part of the algorithm. Deterministic solver can employ any method that provides this data and in this work uses method of moments. With this information, stochastic part of the algorithm employs kinetic Monte Carlo algorithm to simulate chains one-by-one. The computational load of simulating the whole ensemble is eliminated by getting the mean-field background information from deterministic solvers as concentrations of polymer populations and small molecules at certain time intervals. CBC-MC is suited for chemistries, or situations in which the chain architecture develops slowly with respect to the background environment such as controlled reversible-deactivation radical polymerizations. This method is applied to two case studies for synthesis of linear gradient copolymers. First case study is a styrene/ methyl methacrylate copolymerization by nitroxide-mediated polymerization with forced gradient techniques and the second one is the synthesis of methyl methacrylate/ methyl acrylate hyberbolic gradient copolymerization by atom-transfer radical polymerization again with forced gradient techniques. Gradient distribution of chain properties is analyzed in all cases since it is relatively more challenging and interesting. Chain properties such as number average chain length, weight average chain length, polydispersity index, cumulative and instanteneous copolymer compositions, full molecular weight distributions and sequence length distributions are obtained and compared to results from method of moments and kinetic Monte Carlo methods for di↵erent sample sizes. Results were in good agreement with wellestablished method of moments and kinetic Monte Carlo methods. Importance of simulating chain microstructure rather than average properties is made clear. Simulation times were reduced by at least a factor of six compared to kinetic Monte Carlo method. Results confirm that if applicable, full information regarding the microstructure of chains can be obtained using this method with reduced simulation times and smaller sample sizes. This method is also applied to non-linear copolymerization of acrylamide/N,N-methylenebis(acrylamide) (AM/BisAM) leading to gelation. The e↵ect of a gradient distribution of pendant double bonds along the primary chains on the simulated portion of gel molecules is investigated with the aim of detecting the macro-heterogeinities. Five cases are studied with di↵erent feeding policies but same total number of comonomers introduced to each of them. Primary chain results are compared with MOM for cumulative and instantaneous BisAM compositions, crosslink and PDB densities and found to be in excellent agreement. Further investigations are done on primary chain microsturctures to better understand multiple phenomena going on in these systems such as the age distribution of crosslinking points and PDBs, density of crosslinking points and PDBs in monomer bins along the primary chains and average segment lengths. It has been found that a gradient in PDB distribution along the primary chains can introduce heterogeneities into the gel molecules in surface-bound type polymerizations where primary chains within gels are aligned in the same direction but these heterogeneities seem to be disappearing in bulk polymerizations where the chain alignments are random.

Show moreMatrix decomposition and computation constitute an important part of various signal processing, image processing, and communication systems. A better solution in terms of power, performance, and area, can lead to improved performance of the whole system. Designing and testing a new idea is a big challenge due to time limitations. So, a better implementation flow using High-Level Synthesis is discussed. This flow is used to implement QR decomposition algorithms. Three different QR factorization techniques, Gram-Schmidt, Givens Rotation, and Householder Transformation is discussed. These algorithms are compared in terms of area, performance, and precision. All the algorithms are implemented with two different variations in terms of the data type used. A 32-bit floating-point implementation and 16-bit fixed-point implementation are discussed. Results for different designs with various optimization techniques like loop unrolling and pipelining are presented. A scalable architecture is implemented for all the algorithms which are compared for a 10 × 10 matrix architecture. Results for scaled up 100 × 100 matrix architecture are also discussed for the Gram- Schmidt algorithm. Gram-Schmidt had the best performance in all. The performance of Gram Schmidt algorithm was improved by a factor of 3 for 10 × 10 matrix size and by a factor of up to 10 for 100 × 100 matrix size using different optimizations. Givens rotation was close in terms of performance, but the Householder Transformation was four times slower compared to other two algorithms, the reason being the high complexity of the algorithm. All floating-point implementations had nearly 100% precision but varied from 3% to 5% in average error for fixed-point data-type for a 10 × 10 implementation. All the algorithms were coded in C++ and synthesized using High-Level Synthesis using Xilinx Vivado HLS 2016.4 tool. This generated an IP core which was imported to Xilinx Vivado 2016.4 for implementation. The design was targeted for Zedboard, a Zynq – 7020 Extensible Processing Platform (EPP) Development Kit, which has a 7 series Xilinx FPGA architecture and a dual core ARM Cortex A-9 processor.

Show moreGrain boundary engineering (GBE) has been used to improve the properties of various polycrystalline materials by optimization of their grain boundary network. Traditional processing routes for GBE often require multiple iterations of cold work followed by short annealing cycles where each iteration imparts a modest increase in the fraction of special grain boundaries. Multiple iterations are then required to achieve sufficiently high fractions (>50%) that result in the improved properties. Thus, this GBE approach is not suitable for the fabrication of large, complex-shaped structures and leads to added manufacturing lead time and cost. In this investigation, the Ni-base superalloy RR1000 used as turbine discs in gas turbine engines manufactured by Rolls-Royce, was considered for GBE using alternative processing routes more suitable to the forging of Ni-base superalloy components. A preliminary study of the e↵ects of hot deformation parameters closer to typical industrial processing revealed that the length fraction of ⌃3 boundaries increased from 35% to 52% following a single deformation/anneal cycle. Deformation parameters that resulted in strain accommodation via superplastic flow did not enhance the formation of ⌃3 boundaries upon annealing. Whereas deformation parameters that resulted in a dominant dislocation-based plasticity flow mechanism promoted the formation of annealing twins. Using misorientation maps and by estimating the stored strain energy from deformation, equations for the length fraction and density of ⌃3 boundaries were generated for high-temperature GBE of RR1000. The grain boundary characters obtained via high-temperature deformation, however, are less ideal than those resulting from traditional cold rolling. The underlying mechanisms responsible for the formation of ⌃3n boundaries during high-temperature GBE were further investigated. A larger starting grain size prior to deformation was found to be unfavorable to the formation of twin boundaries from twin-reorientation and annihilation of preexisting twins. While recrystallization was found to populate the microstructure with grains that contained very few twin boundaries, post-deformation texture was found to promote the formation of ⌃3 boundaries and triple junctions when Goss texture was present. A final consideration of larger scale forgings was used to raise an outlook on the current issues and the potential of high-temperature GBE for turbine engines.

Show moreHeart failure results in significant morbidity and mortality for those afflicted. The current gold standard treatment is allogenic heart transplantation, however insufficient supply of donor organs limits the effectiveness of this treatment to ideal candidates. This has led to interest in mechanical circulatory support. The most recent generation of devices are smaller, continuous-flow devices with increased durability compared to their predecessors. However, these new devices exhibit increased rates of hemostatic events – both thromboembolic and hemorrhagic. This thesis details an in vivo evaluation of hemostatic parameters in a bovine animal model to evaluate the effect of the ventricular assist device (VAD), and compares these results to what has been seen clinically. Most importantly this thesis has found that bovines do not experience pathophysiologic degradation of high molecular weight Von Willebrand Factor (VWF) as a result of VAD placement, whereas this complication is well documented in humans. This is due to a decreased sensitivity to shear stress induced cleavage of VWF in bovines when compared to humans, as demonstrated in this thesis. Due to the inability to replicate clinical conditions with the bovine animal model, this thesis develops an alternative methodology using an in vitro flow loop using the same human donor blood on all pumps tested. This methodology eliminates the need for interspecies extrapolation; allows for more direct comparisons by eliminating donor variation; and is both cheaper and faster than animal models. This methodology could provide an invaluable option for evaluating hemostatic effects of various pump design parameters.

Show moreA comparison of mutant versus wild type versions of the Vitreoscilla hemoglobin gene (vgb) were the focus of this study. E. coli DH5a cells were transformed with recombinant pUC plasmids containing either the wild type or one of a series of mutated versions of the vgb gene. The study was conducted in two pmis. In the first part, eight strains in total were tested (one plasmid-free negative control, one vector-only (pUC18) negative control, one wild type positive control (pUC8: 16), and five mutants (pUC vgb M1-4 and pUC18 vgb M3)) and comparisons were made to reveal growth advantage or possible increased Vitreoscilla hemoglobin protein (VHb) expression due to vgb gene mutation. Three different growth assays were carried out to compare growth rates among the eight strains under different oxygen concentration conditions: (1) Luria-Bertani (LB) medium, aerobic growth assay, (2) Terrific Broth (TB) medium, low-oxygen growth assay, and (3) TB medium, microaerobic growth assay. Additionally, a series of carbon monoxide (CO) difference spectra were run to quantify functioning VHb protein concentrations in the different strains grown under each of the aforementioned oxygen concentration conditions. In the second part of the study, the two vgb gene mutants that exhibited the highest growth rates and the wild type version were subcloned into the vector pUC8, transformed into E. coli DH5a cells, and then compared using the CO difference spectrum assay. Five E. coli DH5a strains were tested (one plasmid-free negative control, one vector-only negative control (pUC8), one vgb wild type positive control (pUC8 vgb WT), and two vgb mutants (pUC8 vgb M1 and M3)). Transfmmation of plasmids containing the mutated or unmutated version of the vgb gene was verified through E.Z.N.A. plasmid miniprep with gel electrophoresis and additionally through growth on selective medium containing ampicillin (Amp) [50 micrograms (ug)/ milliliter (ml)]. Contrary to the results obtained by our Australian collaborators, our growth assays and CO difference spectra revealed no growth advantage or increased expression of functioning VHb protein due to any of the vgb mutations.

Show moreThe hardware support for the Decimal Multiplication is gaining importance in commercial applications including banking, accounting, tax calculations, currency conversion and insurance. In this work, we examine the di erent types of number sys- tems that have been used for executing Decimal Multiplication. A unique signed-digit representation is used for reduced logic and latency. Furthermore, partial product ac- cumulation is performed with Svoboda decimal adder, which is e cient. The imple- mentation of the proposed architecture is modeled using VHDL and then synthesized on FPGA. The hardware resources for this architecture are analyzed. This work presents an important case study for FPGA implementation of Decimal Arithmetic architectures such as ALUs.
