Show morespectrally accurate boundary integral method is developed for solving the velocity of the film flow with suspended particles down an inclined plane in Stokes flow. The problem is a two-dimensional gravity-driven film flow with a rigid particle flowing down an inclined plane. We present the governing equations and the numerical methods for solving it with the help of periodic Green’s function. To obtain the system of discretized equations, we discuss the smoothness of each integrand appearing in the boundary integral formulation and use the composite trapezoidal rule for smooth periodic integrands to achieve the spectral accuracy. For the weakly singular integral, we approximate it by a special spectrally accurate quadrature. The Krylov subspace iterative method GMRES is employed to solve the resulting linear system. This method can be also applied to compute the velocity of interface in some other cases of film flow.

Show morePeriodic feedback is a control strategy implemented by fast zero-average oscillations in the parameters of the control law. It is well known that time invariant feedback control offers no means for zeros relocation. Periodic feedback allows zeros relocation in an asymptotic sense, resulting in improved closed loop characteristics, such as increased gain margins.

Show moreStigma is an insidious problem that has resulted in loss of opportunities for people with mental illness. Research suggests that contact provided through a structured talk by a person with mental illness could serve as an effective tool in combating stigma and promoting attitude change. Additionally, research on imagined contact suggests this approach can also decrease negative stereotypes toward people with schizophrenia. The current study examined the effectiveness of these two approaches in changing attitudes toward people with mental illness when delivered via the Internet. It was hypothesized that both a videotaped contact and an imagined contact approach would increase positive attitudes and decrease negative attitudes toward people with mental illness when presented alone, and that efficacy would increase when combined. Findings showed no significant changes for any experimental condition from baseline attitudes or relative to a control condition, which suggests that interventions used in this study are not successful in creating sustainable attitude change over the Internet.

Show moreTwo adaptive interviews – adding questions based on low or high scores from a personality assessment – were compared to a structured interview. In a mock selection process, it was found that the adaptive and structured interviews had similar correlations with performance on a role play task. However, due to the added length of the adaptive interview, it had slightly less utility than a structured interview. A cognitive measure and the interview conditions were better predictors of performance than the personality questionnaire, which had no relationship with performance. A post-hoc analysis found that the social desirable scale from the personality instrument correlated negatively with the structured interview, the role play and the IQ test, and positively correlated with the personality composite score.

Show moreWater shortages will be a global problem by the year 2025. With the Great Lakes Basin accounting for 95% of the fresh water in the United States it will soon become our most valuable natural resource. In re-defining urban relationships to the Great Lakes a healthy, ecologically stable, and regenerative water system can become our greatest national asset. Providing a prototype solution for one of these urban areas (Traverse City, MI) may set a precedent for long term protection of the Great Lakes.

Title: OPTIMAL DESIGN OF PERMANENT MAGNET SYNCHRONOUS MACHINES BASED ON MAGNETIC FIELD DISTRIBUTION ASSESSMENT AND PERFORMANCE ANALYSIS
Creator: Jiang, Yong

Show moreThe detailed magnetic field distribution of a permanent magnet electric motor is very important for the accurate prediction of performance parameters such as back electromotive force (back-EMF), rotor and stator losses, winding inductances, noise and vibration, torque profiles, etc. Although finite element analysis is a good option for accurately calculating magnetic field distribution in electrical machines, it is typically timeconsuming and does not provide closed form solutions. Alternatively, analytical calculation of magnetic field distribution can be conducted in Fourier series, which is more suitable for a design tool to predict the motor performance. This dissertation presents a novel numerical technique for calculating exact magnetic field distribution in the air gap of a surface mounted permanent magnet machine. This solution can be obtained via a two-dimension analytical solution with Laplacian and quasi-Poisonian equations, assuming that the iron is infinitely permeable and the air gap is slotless. Slot effects can be added in the model by using relative air gap permeance calculated by the conformal transformation of slot geometry. This technique is constructed by multiplying the relative permeance function expressed in an infinite Fourier series with the distribution of magnetic field in the slotless air gap. This method shows a very good alignment with finite element method for a surface mounted permanent magnet machine with radial magnetization. It can also be extended to calculating magnetic field distribution of interior permanent magnet motors including consideration of magnetic saturation, crosssaturation between d-axis and q-axes, affecting both inductances and flux linkages, as well as localized effects due to rotor bridges. Furthermore, this approach can be used to create a closed-form solution, which is the first step towards inverse modeling of electric machines. This is a complete paradigm shift in the design process for electric machines, which can reduce the time taken to design an electric machine, while reducing the active material content to make them power dense with significant reduction in cost. Furthermore, availability of analytical description of the field components will aid in the designer’s ability to distinguish between the control and magnetic design aspects.

Show moreTechniques for measuring the yield stress of materials are numerous, but often plagued with diffculties and uncertainties in measurement. The primary methods include shear rheometry and, more recently, squeezing ow. Shear rheometry requires care on the part of the experimentalist to generate uniform flow fields and avoid shear banding or wall slip which may interfere with measurements. Squeezing fow tests are often performed with poorly controlled boundary conditions creating complicated flow fields. Further, the effects of the experimental modifications made to produce these boundary conditions in measurements are often not investigated and simply ignored. The main objective of this study was to develop a novel measuring technique to study the yield stress behavior of a model material, Carbopol. First attempts were made towards a novel lubricant injection squeezing (LIS) ow technique based on the continuous lubricated squeezing ow (CLSF) setup, as well as a novel lubricant film squeezing (LFS) technique which will allow measurement of the yield stress without the complicated treatment of either the sample or experimental setup required by currently favored methods. The novel techniques were developed and validated by direct comparison with shear measurements, the current gold standard for determining yield stress. Common squeezing techniques for characterizing yield stress fluids were also compared and found to be inadequate and inconsistent when compared to the shear measurements. The results from this study showed that the LIS and LFS methods are able to qualitatively determine a yield stress, but further investigation is required before they can be achieve their full potential as viable methods for determine yield stress.

Description: At CDF we study charged particle production (pT > 0.5 GeV/c, |η|
Show moreAt CDF we study charged particle production (pT > 0.5 GeV/c, |η| < 0.8) in proton-antiproton collisions at 300 GeV, 900 GeV, and 1.96 TeV. The 300 GeV and 900 GeV data are a result of the “Tevatron Energy Scan” which was performed just before the Tevatron was shut down. We use the direction of the leading charged particle in each event, PTmax, to define three regions of η-φ space; “toward,” “away,” and “transverse.” The “trans- verse” region is further divided into the “transMAX” and “transMIN” con- tributions. The “transMIN” region is very sensitive to the multiple parton interaction component (MPI) of the “underlying event,” while the “trans-DIF” (“transMAX” minus “transMIN”) is very sensitive to the initial and final-state radiation. This CDF analysis together with LHC data provides a detailed study the energy dependence of the various components of the “underlying event” in hadronic collisions.

Show moreFundamental issues about the coupling of twin supersonic jets of complex geometry are examined. It is shown that screech tones from twin rectangular nozzles with double-beveled exit geometries can couple. Unlike coupling of twin rectangular jets of uniform geometry, the coupling here is more intricate because simultaneous multiple frequencies with a different spanwise modal structure are present. The coupling produces two frequencies, one of which is lower than the screech frequency of either jet. Although many coupling modes are kinematically permissible, the twin jets prefer two specific modes, and in some cases these two coupling modes coexist at different frequencies. Despite the geometric complexity we can effectively predict frequencies of tones from both single and twin coupled jets using the waveguide approach. It is hoped that these results and insights will assist those simulating screech for the purpose of tailoring shock-containing complex twin jets that minimize sonic fatigue failure of aircraft structures.

Show moreSlight changes in raw material properties or operating conditions during critical periods of operation of batch and semi-batch polymerization reactors may have a strong influence on reaction mechanism and impact final product quality. Online process monitoring, fault detection, fault diagnosis, and product quality prediction in real-time ensure safe reactor operation and warn operators about excursions from normal operation that may lead to deterioration in product properties. Multivariate statistical process monitoring and quality prediction using multiway principal components analysis and multiway partial least squares have been successful in detecting abnormalities in process operation and product quality. When abnormal process operation is detected, fault diagnosis tools are used to determine the source cause of the deviation. Illustrative case studies are presented via simulated polyvinyl acetate polymerization.

Show moreIn the United States each person consumes about 70 million BTUs per year in the residential sector, a tendency that is constantly growing because of technology and society growth (EIA, 2011). The United States Department of Energy (USDOE, 1988) reported that heat pumps are energy efficient devices that can provide heating and cooling in residential and industrial buildings and also in households. According to Bernier (2006) heat pumps offer many advantages such as decreased space needs, higher efficiencies, and lower maintenance costs, and that is why they have been implemented in many regions throughout the United States as well as in many European countries. However, their use is many times hindered due to the high initial costs relative to conventional heating air conditioning ventilating systems (HVAC), technologies that are widely known and have been used for many years. The purpose of this thesis is to analyze the performance, economic feasibility, and greenhouse gas emission reduction of implementing heat pump devices in drinking water plants for heating and cooling needs inside the building. The proposed system is similar to groundwater heat pumps (described in an upcoming section) but instead of groundwater the heat pump relies on drinking water that has been treated in the plant and it is ready for its use. Groundwater has one main advantage because it is at a constant temperature year round (NRC, 2005) which gives the heat pump system stability in its behavior. Moreover, it is at a higher temperature than air in winter, and at a lower temperature than air in summer, which makes it an excellent candidate for heat transfer purposes in the refrigeration cycle. The four cases studies described in this work examine medium and high efficiency heat pumps installed in existing plants and new plants. Because drinking water is readily available after its treatment, the cost of drilling and grouting is avoided and this high quality water also avoids most of the problems related to quality of water such as scaling or fouling. This system gives a return of investment that is in all cases lower than six years. emissions are reduced by about 50 per cent because the use of a much more efficient device produces less for each kWh of heating or cooling delivered in the building.

Show moreThis paper demonstrates the application of PLS regression, balanced realization, and canonical variate (CV) state space modeling techniques in identifying stationary vector autoregressive moving average (VARMA) type of time series models in state space. An example VARMA process model is used to generate data, carry out modeling activities, and compare the three model development techniques. All realization methods provide equivalent state space models. Balanced realization can not handle singularities in the covariance matrix of past observations while all other methods can accommodate such singularities. Balanced realization and classical PLS do not provide minimal state variables that are orthogonal. 'Orthogonal states' PLS and canonical variate state space realization give orthogonal state variables that provide robust parameter estimates from real data, however the PLS method requires an additional singular value decomposition step.

Show moreThis thesis describes the effort in designing SRAMs based on Carbon Nanotube Field Effect Transistor (CNFET), and covers several aspects including circuit structure, parameters, layout and the detection of diameter variation. It aims at providing a primitive reference on the topic of employing CNFETs in realistic SRAM design. In this thesis, we propose a guideline for choosing appropriate transistor ratios with respect to differently selected diameters in a conventional 6-T SRAM. Constraints of transistor ratios are established, followed by the optimization of the ratios regarding Static Noise Margin (SNM) and Read Noise Margin (RNM) of the cell. With the optimal parameters, the CNFET cell can achieve 41.41% and 1.26% improvement over traditional CMOS in SNM and RNM, respectively. Then we propose a column-based monitoring circuit which is capable of detecting variation in the diameter of tubes. It is grounded on a novel layout of the 6-T SRAM based on CNFET, which assigns all cells in a column of the SRAM array to the same group of Carbon Nanotubes (CNTs). This monitor outputs a digital signal indicating the impact of diameter variation on delay of the circuit, and enables further mitigation of the variation. Alternatively, a new 6-T SRAM cell structure is proposed for optimizing the performance of the cell at very-low or sub-threshold supply voltages. Compared with a traditional 6-T cell, simulation results show that the reading and writing delay have been improved by more than 80% and 75% at 0.4V supply voltage, respectively. It achieves PDP reduction of 70% and 91% for reading and writing operations.

Show moreMy project is an urban redevelopment following catastrophe. A catastrophic explosion in 2010 left a portion of Nanjing city destroyed. The project proposes a new urban plan to rebuild the neighborhood and restore the community. A powerful explosion at an abandoned plastics factory in Qixia district of Nanjing city has left several people dead and dozens injured. Buildings and vehicles within 100m of the factory destroyed, 3000 citizen got the key of the street and buildings suffered varying degrees of damage in the area 8 miles in circumference. The blast was caused by a leak from a gas pipeline inside the factory, the blast happened after workers dismantling the plant damaged a propylene pipeline. The leaked gas was then ignited when a car engine was started at the scene. There were a community college and several kindergartens in this area, fortunately, it was summer break at that time, no students hurt reported. It is a unique opportunity to develop a plan in an urban context when the prior years of development have been wiped away. The purpose of the project is giving condos return to 3000 people who lost their houses in the explosion and planing mix-used buildings of the community for next 20 years. At present, many old nerghbourhoods in China are being replaced by new ones. In the most cases, the existing urban patternes are erased and a town is built with out any links to what had previouly existed there. My ptoposal is reusing most of the existing tree line streets, river and bridges. The key of this proposal is sustainability, first idea is using existing river to develop a nice wetland park and the second idea is farming gradens.
