Methods For Identifying Acoustic Emissions From The Front Face Of A Small Piezoelectric Blower, Brad K. Solomon

Theses and Dissertations

This thesis focuses on identifying acoustic noise generating components in piezoelectric blowers through transverse velocity measurements and the development of a numerical fluid model. Piezoelectric ceramics have proven useful for many industries and areas of research involving: high precision actuators, noise control, ultrasonic devices, and many other areas. As of late, a unique adaptation of piezoelectric ceramics is surfacing in the area of pumping and cooling. Air pumps that use these ceramics replace the traditional electric motor, resulting in lower power consumption, less moving parts, constant pressure gradients, lower overall weight, and a low profile. The current drawback of this …

Electromagnetic Properties Of Metal Granular Composite Materials For Emc Applications, Takanori Tsutaoka, Aiko Tsurunaga, Teruhiro Kasagi, Kenichi Hatakeyama, Marina Koledintseva

Electrical and Computer Engineering Faculty Research & Creative Works

Electromagnetic properties of copper and Fe₅₅Ni₄₅alloy (Permalloy) composite materials have been studied by measuring the relative complex permeability (µ_r = µ_r’– jµ_r”), and permittivity (Σ_r = Σ_r’– jΣ_r”) spectra over the microwave range, as well as the a.c. electrical conductivity σac spectra. The variation of σ_ac and Σ_r with particle content shows the insulator-metal transition due to the percolation effect. The effective cluster model can be applied to the percolation effect in permittivity. The permeability spectra in Permalloy composites, which contain the percolated particles, …

Analytical Representations For Frequency Dependences Of Microwave Permeability, Konstantin N. Rozanov, Marina Koledintseva

Electrical and Computer Engineering Faculty Research & Creative Works

Electromagnetic materials applied to solve various EMC and EMI problems require adequate analytical description of their RF and microwave material parameters. This is necessary for numerical optimization of wideband electromagnetic performance of devices incorporating these materials. The paper discusses the shape of frequency dependences of microwave permeability in homogeneous materials and composites. The Lorentzian frequency dispersion law is shown to allow for rather accurate description of all types of magnetic loss peaks, including those related to the ferromagnetic resonance and the effect of eddy currents. To model wideband electromagnetic performance of composites, mixing laws are typically used. The problem is …

Alternative Aefie-Efie Method For Broadband Cem Modeling, Jia Liu, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

It is well known that the electric field integral equation (EFIE) has the low frequency breakdown problem while the Augmented electric field integral equation (AEFIE) method has the high frequency breakdown issue. To obtain a unified method that works for both low and high frequencies without manual switching of methods, a novel and simple method is proposed in this paper. It uses AEFIE and EFIE to compensate each other iteratively in all frequency regimes to guarantee the accuracy of the solution. As a result, it effectively extends AEFIE to the high frequency regime and extends EFIE to the low frequency …

Capacitance Calculation Of Tsvs Using An Integral Equation Method Based On Partial Capacitances, Hanfeng Wang, Yaojiang Zhang, Albert E. Ruehli, Jun Fan

Electrical and Computer Engineering Faculty Research & Creative Works

An integral equation method based on partial capacitances is used to extract the capacitance between two through-silicon-vias (TSVs). the unrealistic assumption of equal potential along the vertical interface of silicon dioxide (SiO2) coating of TSVs in the analytical method has been removed by introducing unknown equivalent charges. the Galerkin method is used here to solve the unknown charge densities in the integral equation and thus, the capacitance between two TSVs can be efficiently calculated. the results are validated by comparing the extracted capacitances with commercial software based on the finite element method. the accuracy and efficiency have been demonstrated. © …

Speed-Up Of Peec Em/Ckt Solver Using Rank-Reduced Waveform Relaxation, Giulio Antonini, Albert E. Ruehli

Electrical and Computer Engineering Faculty Research & Creative Works

The solution of EM/Circuit problems is important for the EMC/SI/PI system designs. an essential issue today is the solution of larger problems without excessive memory and compute time requirements. in this paper, we show the potential for a new speed-up approach using the PEEC method. One source of the speed-up is due to the use of the waveform relaxation (WR) technique, which is very suitable for parallel processing. Importantly, the dense part of the partial inductance and potential matrices are sparsified by taking advantage of the rank deficiency of the dense parts of the MNA matrix. We show that both …

Fast Admittance Computation For Tsv Arrays, Dazhao Liu, Siming Pan, Brice Achkir, Jun Fan

Electrical and Computer Engineering Faculty Research & Creative Works

A fast method to calculate the admittance matrix of through Silicon Vias (TSVs) is proposed in this paper. the silicon dioxide layers are equivalently modelled using the bound charge on the conductor surfaces as well as on the dielectric interface between the silicon dioxide and the silicon regions. Unknown surface densities of both the free and bound charge are expanded using the axial harmonics. Galerkin's method is then applied to obtain the capacitance and conductance matrices. the proposed method is validated with a full wave 2D cross-sectional analysis tool for a typical TSV pair structure. Comparisons with popular closed-form expressions …

Using Fsv In High-Speed Channel Characterization And Correlation, Jiangfan Zhang, Jianmin Zhang, Jane Lim, Kelvin Qiu, Rick Brooks, Bill Chen

Electrical and Computer Engineering Faculty Research & Creative Works

In modern high performance networking systems, high-speed channels are among the most concerns due to the channel loss, discontinuities and crosstalk as data rate reaches 15 Gbps (Gigabit per second) and above through backplane. Full-wave modeling and system level simulations are widely used to estimate the performance for high-speed channels. Due to the variations and uncertainties associated with the simulation and manufacturing, correlation between simulation and measurement is often used to gain confidence on the channel performance prediction. in this paper, a high-speed channel including the portion inside a high-end ASIC (Application-Specific Integrated Circuit) package and the portion on a …

A Simplified Onsite Image-Registration Approach For Radiosurgery By Partial Ct, Wupeng Yin

Open Access Theses

Stereotactic radiosurgery (SRS) is a kind of method of radiation therapy that uses three-dimensional computerized imaging to precisely guide a high-powered X-ray beam to deliver a concentrated dose of radiation to the abnormal area of the body. This therapy can efficiently and successfully treat many different types of tumors, either benign or malignant. Commonly used radiosurgery treatments are applied by CyberKnife or Gamma Knife through Stereotactic mechanism. Stereotactic radiosurgery can be assisted by two and three dimensional imaging during a course of radiation treatment. This is usually called Image-guided radiation therapy (IGRT), which utilizes the imaging coordinates to direct radiation …

Time Overruns As Opportunistic Behavior In Public Procurement, Chiara D’Alpaos, Michele Moretto, Paola Valbonesi, Sergio Vergalli

Fondazione Eni Enrico Mattei Working Papers

This paper considers the supplier’s strategic delivery lead time in a public procurement setting as the result of the firm’s opportunistic behaviour on the optimal investment timing. In the presence of uncertainty on construction costs, we model the supplier’s option to defer the contract’s execution as a Put Option. We include in the model both the discretion of the court of law in enforcing contractual clauses (i.e. a penalty for delays) and the "quality" of the judicial system. Then, we calibrate the model using parameters that mimic the Italian procurement for public works and calculate the maximum amount that a …

A Regionalized National Universal Kriging Model Using Partial Least Squares Regression For Estimating Annual Pm2.5 Concentrations In Epidemiology, Paul D. Sampson, Mark Richards, Adam A. Szpiro, Silas Bergen, Lianne Sheppard, Timothy V. Larson, Joel Kaufman

UW Biostatistics Working Paper Series

Many cohort studies in environmental epidemiology require accurate modeling and prediction of fine scale spatial variation in ambient air quality across the U.S. This modeling requires the use of small spatial scale geographic or “land use” regression covariates and some degree of spatial smoothing. Furthermore, the details of the prediction of air quality by land use regression and the spatial variation in ambient air quality not explained by this regression should be allowed to vary across the continent due to the large scale heterogeneity in topography, climate, and sources of air pollution. This paper introduces a regionalized national universal kriging …

A Guide To Documenting Software Design For Maximum Software Portability For Software Defined Radios, Joseph Snively

Regis University Student Publications (comprehensive collection)

The use of software defined communications systems is growing incredibly fast. The field of software engineering as a discipline has not adequately addressed the subject of software portability which makes large and costly software development efforts less ready to port to future platforms. By understanding the causes of portability problems, they can either be avoided altogether in development or very well documented so that they are easier to overcome in future efforts. Literature, case studies, and surveys are used to collect opinions and information about large software programs where portability is a desirable characteristic in order to best establish the …

Manipulation Of Plants By Transformation With Sequences Promoting Cell Division, Victor B. Busov, Steven H. Strauss

Michigan Tech Patents

Polynucleotides encode polypeptides for increasing the rate of growth of plants. Introduction of the polynucleotides into plants produces plants having altered characteristics, such as increased growth, increased leaf area and reduced fertility. Expression of polypeptides in plants or plant cells promotes cell division. Expression of the polynucleotides in plants in the antisense orientation produces plants that are sterile or have smaller leaves.

Lithium Storage Mechanisms In Purpurin Based Organic Lithium Ion Battery Electrodes, Arava Leela Mohana Reddy, Subbiah Nagarajan, Porramate Chumyim, Sanketh R. Gowda, Padmanava Pradhan, Swapnil R. Jadhav, Madan Dubey, George John, Pulickel M. Ajayan

Publications and Research

Current lithium batteries operate on inorganic insertion compounds to power a diverse range of applications, but recently there is a surging demand to develop environmentally friendly green electrode materials. To develop sustainable and eco-friendly lithium ion batteries, we report reversible lithium ion storage properties of a naturally occurring and abundant organic compound purpurin, which is non-toxic and derived from the plant madder. The carbonyl/hydroxyl groups present in purpurin molecules act as redox centers and reacts electrochemically with Li-ions during the charge/discharge process. The mechanism of lithiation of purpurin is fully elucidated using NMR, UV and FTIR spectral studies. The formation …

Reliability Techniques For Data Communication And Storage In Fpga-Based Circuits, Yubo Li

Theses and Dissertations

This dissertation studies the effects of radiation-induced single-event upsets (SEUs) on field-programmable gate array(FPGA)-based circuits. It analyzes and quantifies a special case in data communication, that is, the synchronization issue of signals when they are sent across clock domains in triple modular redundancy (TMR) circuits with the presence of SEUs. After demonstrating that synchronizing errors cannot be eliminated in such case, this dissertation continues to present novel synchronizer designs that can guarantee reliable synchronization of triplicated signals. Fault injection tests then show that the proposed synchronizers provide between 6 and 10 orders of magnitude longer mean time to failure (MTTF) …
