Mechanical Engineering Faculty Research and Publications

There is considerable interest in developing a better understanding of the dynamic behavior of heterogeneous materials. This study investigates and compares the dynamic response of 20 and 47% dense aluminum foam systems with and without a polytetrafluoroethylene (PTFE or Teflon) fill. Experiments on 47% foam were conduced in a 60 mm bore gun in a reverse ballistic configuration at velocities ranging from 350 m/s to 2.5 km/s. The particle velocity of the backside of the anvil was monitored with a VISAR system. Mesoscale simulations are in good agreement with the available experimental data. Both the experimental and simulated data are …

The Inevitable Irrelevance Of Affirmative Action, Leslie Y. Garfield

Elisabeth Haub School of Law Faculty Publications

This article proceeds in three parts. In Part I of this article, I provide a narrative of affirmative action jurisprudence in higher education, with a particular focus on the meaning of viewpoint diversity in higher education. This section tracks the definitional shift in preference policies from their original design as remedial and compensatory programs for those suffering the effects of educational discrimination to interest convergence programs, which assure equal benefits irrespective of race. In Part II, I explore the circumstances giving rise to Fisher, including an overview of the lower court decisions. This section presents a discussion of the likely …

Dynamic Governance Innovation, Elizabeth Burleson

Elisabeth Haub School of Law Faculty Publications

This article frames environmentally sound innovation in the context of transnational network theory with the goal of setting forth a preliminary framework for international legal policy coherence. I consider how network dynamics can facilitate broad diffusion of environmentally sound technologies, concluding that what appears to be fragmented trade, environment, and human rights regimes are indeed sustainable development building blocks with which to achieve dynamic governance. Collaborative environmentally sound innovation networking may be able to shepherd whole renewable energy sectors across the innovation valley of death and help turn a global responsibility to ramp up green technology into a global initiative …

Interpreting Precise Constitutional Text: The Argument For A “New” Interpretation Of The Incompatibility Clause, The Removal & Disqualification Clause, And The Religious Test Clause—A Response To Professor Josh Chafetz’S Impeachment & Assassination, Seth Barrett Tillman

Cleveland State Law Review

In an article in another journal, Professor Josh Chafetz wrote: “[I]mpeachment maintains the link between removal and death, but attenuates it. . . . Impeachment is . . . a political death—a President who is impeached and convicted is deprived of his continued existence as a political officeholder. And, like death, impeachment and conviction may be permanent.” In this response, it is my purpose to show that Chafetz’s proposed metaphor does not work and, indeed, that inferences drawn from this metaphor lead Chafetz far afield from the Constitution’s original public meaning. But before doing so, I think it might be …

The Good, The Bad, And A New Kind Of Prenup: An Analysis Of The Ohio Legacy Trust Act And What Asset Protection Trusts Will Mean For Ohio, Kevin R. Mckinnis

Cleveland State Law Review

It is human nature to want to protect what one has worked hard to earn or accomplish. It is this very nature that entices individuals to search for creative methods by which to protect one’s assets, whether from high tax rates or creditors. As laws continually change, individuals strive to protect their assets in the most effective and secure manner possible. As a result, the protection of one’s assets has evolved from the use of offshore Asset Protection Trusts (APTs) to the use of domestic APTs (DAPT). The Ohio Legacy Trust Act is an attempt to modernize Ohio’s wealth management …

Aquaponics: A Sustainable Food Production System That Provides Research Projects For Undergraduate Engineering Students, Richard W. Marklin Jr., Margaret Mathison, Brooke K. Mayer, Mark L. Nagurka, Vikram Cariapa, Jay Schabelski

Mechanical Engineering Faculty Research and Publications

Aquaponics is a closed-loop, recirculating water system in which plants and fish grow together mutualistically. Aquaponics resembles a natural river or lake basin in which fish waste serves as nutrients for the plants, which in turn clean the water for the fish. Tilapia and salad greens or herbs are common fish and plants grown in an aquaponics system. The external inputs to an aquaponics system are fish food, minimal amount of water, and energy for lighting and heating the water for the fish and plants.

Aquaponics is a sustainable, efficient system to raise fish protein and vegetables for human consumption. …

Numerical Study Of Pressure Fluctuations Due To A Mach 6 Turbulent Boundary Layer, Lian Duan, Meelan M. Choudhari

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Direct numerical simulations (DNS) are used to examine the pressure fluctuations generated by a Mach 6 turbulent boundary layer with nominal freestream Mach number of 6 and Reynolds number of Reτ ≈ 464. The emphasis is on comparing the primarily vortical pressure signal at the wall with the acoustic freestream signal under higher Mach number conditions. Moreover, the Mach-number dependence of pressure signals is demonstrated by comparing the current results with those of a supersonic boundary layer at Mach 2.5 and Reτ ≈ 510. It is found that the freestream pressure intensity exhibits a strong Mach number dependence, irrespective of …

Modeling And Testing Of An R-23/R-134a Mixed Refrigerant System For Low Temperature Refrigeration, Nicholas Hugh, Margaret Mathison, Anthony Bowman

Mechanical Engineering Faculty Research and Publications

Low temperature refrigeration storage equipment in the biotechnology industry typically uses cascade refrigeration to achieve evaporating temperatures of -80 °C (-112 °F) or below. Current systems utilize multiple compressors leading to high energy consumption. Equipment operating costs contribute significantly to the total operating costs of biotechnology companies and therefore motivate the development of more efficient alternatives for low temperature refrigeration. This paper describes a single compressor R-23/R-134a mixed refrigerant cycle that has been designed to extract a load of 0.256 kW (873.5 Btu/hr) from a conditioned space at -80 °C (-112 °F). The designed system compresses a mixture of the …

Creating Cayman As An Offshore Financial Center: Structure & Strategy Since 1960, Tony Freyer, Andrew P. Morriss

Faculty Scholarship

The Cayman Islands are one of the world's leading offshore financial centers (OFCs). Their development from almost a barter economy in 1960 to a leading OFC for the location of hedge funds, captive insurance companies, yacht registrations, special purpose vehicles, and international banking today was the result of a collaborative policy-making process that involved local leaders, expatriate professionals, and British officials. Over several decades, Cayman created a political system that enabled it to successfully compete in world financial markets for transactions, participate in major international efforts to control financial crimes, and avoid the political, economic, racial, and social problems that …

A Wide-Band Equivalent Source Reconstruction Method Exploiting The Stoer-Bulirsch Algorithm With The Adaptive Frequency Sampling, P. Li, Y. Li, Lijun Jiang, J. Hu

Electrical and Computer Engineering Faculty Research & Creative Works

Conventional equivalent source reconstruction methods are only operating at a single frequency point each time. However, for wide-band radiators, their computation cost of the source reconstruction increases with the number of frequency points. In this communication, a wide-band equivalent source reconstruction method (WB-SRM) based on the Neville-type Stoer-Bulirsch (SB) algorithm is developed. Since the SB algorithm is a recursive tabular method, it can perform the interpolation over a broadband using a single rational function without any singularity issue. Supported by the adaptive frequency sampling (AFS) scheme, the number of required sampling data is significantly reduced, which leads to much better …

Land Use And Climate Change: Lawyers Negotiating Above Regulation, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

Sea level rise requires a new paradigm for controlling the development of coastal lands that are in harm’s way, calling for adjustments in the law, legal practice, and legal education. This article discusses the historical tendency of the law to adjust to changes in society and the recent emergence of new legal institutions and strategies for mitigating and adapting to climate change, particularly sea level rise. It illustrates how the lack of certainty about the extent and pace of sea level rise collides with the total takings doctrine of the Lucas case to frustrate the application of traditional land use …

Privacy Laws And Privacy Levers: Online Surveillance Versus Economic Development In The People’S Republic Of China, Ann Bartow

Elisabeth Haub School of Law Faculty Publications

This Essay describes and contextualizes the ongoing efforts by the Communist Party of China (CPC) to reconcile two dramatically competing interests: the desire to extensively monitor the communications of its citizenry, and a burning ambition to further develop its banking and financial industries, its high tech innovation capabilities, and its overall share of the “knowledge economy.”

Monitoring and censoring communications, especially via “one-to-many” social networking platforms, is viewed as essential for the prevention of mass anti-Party political activities ranging from peaceful civil disobedience to armed insurrection and for the protection of the reputations of individual Party leaders. Mobile Internet technologies …

Inverted Takotsubo Cardiomyopathy And The Fundamental Diagnostic Role Of Echocardiography, Arantza Manzanal, Lara Ruiz, Jose Madrazo, Majesh Makan, Julio Perez

The Texas Heart Institute Journal

Takotsubo cardiomyopathy is characterized by the development of transient focal wall-motion abnormalities that involve the apical and midventricular segments, in the absence of obstructive coronary artery disease. A variant, inverted takotsubo cardiomyopathy, was described in 2010. We report 3 cases in which each patient's transthoracic echocardiogram revealed the characteristic basal and midventricular segmental akinesis of this variant. This pattern is not associated with coronary artery distribution, and it therefore can be differentiated from coronary artery disease with the use of echocardiography, by evaluating the distribution and temporal changes of akinetic areas.

The Texas Heart Institute Journal

The present study was undertaken to investigate, in an animal model, the relationship between sarcoplasmic reticulum Ca2+-ATPase (SERCA2a) activity, phospholamban phosphorylation, acylphosphatase activity, and hemodynamic changes that occur in the early phase of pressure overload. In 54 study-group pigs, weighing 40±5 kg each, an aortic stenosis was created with a band of umbilical tape tied around the aorta; 18 sham-operated pigs formed our control group. Eight animals (6 study and 2 control) were randomly assigned to each experimental time (0.5, 3, 6, 12, 24, 48, 72, 96, and 168 hr). All indices of left ventricular function declined significantly, with a …

Osteosarcoma Tumor Thrombus: A Case Report With A Review Of The Literature, Pournima Navalkele, Sarah M Jones, Jason K Jones, Jorge D Salazar, Patrick C Toy, Rathi V Iyer, Betty Herrington

The Texas Heart Institute Journal

Tumor thrombus arising from osteosarcoma is rare. We report the case of a 20-year-old man with proximal humerus osteosarcoma, accompanied by an extensive intravascular tumor thrombus extending into the heart. Our review of the literature found 14 previous reports on osteosarcoma with tumor thrombus. The combination of positron emission tomography and computed tomography is very useful in differentiating tumor thrombus from vascular thrombus, thereby avoiding unnecessary anticoagulation therapy. This same imaging combination can also be used to evaluate the response to treatment. Surgical resection of the tumor thrombus is highly recommended. The effect of tumor thrombus on survival is still …

Mitochondrial Cardiomyopathy: Pathophysiology, Diagnosis, And Management, Deborah E Meyers, Haseeb Ilias Basha, Mary Kay Koenig

The Texas Heart Institute Journal

Mitochondrial disease is a heterogeneous group of multisystemic diseases that develop consequent to mutations in nuclear or mitochondrial DNA. The prevalence of inherited mitochondrial disease has been estimated to be greater than 1 in 5,000 births; however, the diagnosis and treatment of this disease are not taught in most adult-cardiology curricula. Because mitochondrial diseases often occur as a syndrome with resultant multiorgan dysfunction, they might not immediately appear to be specific to the cardiovascular system. Mitochondrial cardiomyopathy can be described as a myocardial condition characterized by abnormal heart-muscle structure, function, or both, secondary to genetic defects involving the mitochondrial respiratory …

Low Serum Triglyceride Levels As Predictors Of Cardiac Death In Heart Failure Patients, Guliz Kozdag, Gokhan Ertas, Ender Emre, Yasar Akay, Umut Celikyurt, Tayfun Sahin, Gozde Gorur, Kurtulus Karauzum, Irem Yilmaz, Dilek Ural, Mira Sarsekeyeva

Two Cases Of Bezold-Jarisch Reflex Induced By Intra-Arterial Nitroglycerin In Critical Left Main Coronary Artery Stenosis, Sachin P Shah, Sergio Waxman

The Texas Heart Institute Journal

The Bezold-Jarisch reflex, a well-described phenomenon, occurs upon the stimulation of intracardiac mechanoreceptors and is mediated by vagal afferent nerve fibers. Several factors can sensitize the cardiovascular system to develop this reflex, including acute myocardial ischemia, natriuretic peptides, and, rarely, nitroglycerin administration in the setting of acute myocardial infarction. The development of the Bezold-Jarisch reflex in the presence of severe coronary artery stenosis, specifically left main coronary artery stenosis, has not been described. We report 2 cases of patients who underwent elective coronary angiography and were given intra-arterial nitroglycerin during radial sheath insertion to reduce radial artery spasm. In both …

Perventricular Device Closure Of Residual Muscular Ventricular Septal Defects After Repair Of Complex Congenital Heart Defects In Pediatric Patients, Da Zhu, Kaiyu Tao, Qi An, Shuhua Luo, Changping Gan, Ke Lin

The Texas Heart Institute Journal

Residual muscular ventricular septal defects are surgical challenges, especially after the repair of complex congenital heart defects. We investigated perventricular device closure as a salvage technique in pediatric patients who had postoperative residual muscular ventricular septal defects.

From February 2009 through June 2011, 14 pediatric patients at our hospital had residual muscular ventricular septal defects after undergoing surgical repair of complex congenital heart defects. Ten patients met our criteria for perventricular device closure of the residual defects: significant left-to-right shunting (Qp/Qs >1.5) or substantial hemodynamic instability (a defect ≥2 mm in size). The patients' mean age was 20.4 ± 13.5 …
