Vibration Control Of Buildings Using Magnetorheological Damper: A New Control Algorithm, Aly Mousaad Aly

Faculty Publications

This paper presents vibration control of a building model under earthquake loads. A magnetorheological (MR) damper is placed in the building between the first floor and ground for seismic response reduction. A new control algorithm to command the MR damper is proposed. The approach is inspired by a quasi-bang-bang controller; however, the proposed technique gives weights to control commands in a fashion that is similar to a fuzzy logic controller. Several control algorithms including decentralized bang-bang controller, Lyapunov controller, modulated homogeneous friction controller, maximum energy dissipation controller, and clipped-optimal controller are used for comparison. The new controller achieved the best …

Hydrogeochemical Analysis For Tasuj Plain Aquifer, Iran, Ata Allah Nadiri, Asghar Asghari Moghaddam, Frank T.C. Tsai, Elham Fijani

Faculty Publications

This study investigated the hydrogeochemical processes of groundwater in the Tasuj plain, Iran. The Tasuj plain is one of the 12 marginal plains around Urmia Lake which is currently under a critical ecological condition. In the last decades, the Tasuj plain aquifer suffered from severe groundwater level declination and caused degradation of groundwater quality. To better understand hydrogeochemical processes in the Tasuj plain, this study adopted graphical methods and multivariate statistical techniques to analyze groundwater samples. A total of 504 groundwater samples was obtained from 34 different locations (qanats, wells, and springs) over 12 years (1997-2009) and analyzed for 15 …

Supervised Committee Machine With Artificial Intelligence For Prediction Of Fluoride Concentration, Ata Allah Nadiri, Elham Fijani, Frank T.C. Tsai, Asghar Asghari Moghaddam

Faculty Publications

The study introduces a supervised committee machine with artificial intelligence (SCMAI) method to predict fluoride in ground water of Maku, Iran. Ground water is the main source of drinking water for the area. Management of fluoride anomaly needs better prediction of fluoride concentration. However, the complex hydrogeological characteristics cause difficulties to accurately predict fluoride concentration in basaltic formation, non-basaltic formation, and mixing zone. SCMAI predicts fluoride by a nonlinear combination of individual AI models through an artificial intelligent system. Factor analysis is used to identify effective fluoride-correlated hydrochemical parameters as input to AI models. Four AI models, Sugeno fuzzy logic, …

Las Actividades De Formación Docente: Una Mirada A Los Cursos Estatales De Actualización De Los Profesores De Secundaria, Haideé Franco Moreno, Tiburcio Moreno Olivos

Faculty Publications

The aim of this project is to give a voice to the teachers who have participated in the Upgrading State Courses (CEA) organized by the National Teachers' Upgrading Program (PRONAP), and applied throug the Teachers Centers, in order to recognize the meaning given to the activity called “upgrading” and thus to understand if the teachers who participated in such Courses managed to develop any reflective process derived from this experience, or if they attended to trifling courses that only tried to alienate and looked for dogmatisms, leaving aside the condition of possibility and existence.

The paradigm followed in this research …

Optimizing A Continuous Flow Lipid Extraction System (Cfles) Used For Extracting Microalgal Lipids, Javed Iqbal, Chandra Theegala

Faculty Publications

A laboratory-made continuous flow lipid extraction system (CFLES) was devised to extract lipids from microalgae Nannochloropsis sp., a potential feedstock for biodiesel fuel, with a focus to assess the workable temperatures and pressures for future industrial applications. Using conventional solvents, the CFLES recovered 100% of the lipids extracted with conventional Soxhlet extraction. The optimum temperature and pressure were found to be 100 °C and 50 psi, respectively; conditions significantly lower than those normally used in pressurized liquid extractions requiring specialized equipment. Approximately 87% of the extracted oil was successfully transesterified into biodiesel fuel (fatty acid methyl esters). Preliminary calculations based …

Charter Schools, Vouchers, And The Public Good, Derek W. Black

Faculty Publications

Charter schools and vouchers have thus far been promoted or vilified based on their potential to improve academic achievement for those students enrolled in them. This debate, however, ignores a more important question: whether these educational policies serve the public good. Education as a public good cannot be reduced solely to questions of academic achievement, much less the academic achievement of a subset of students. Theoretically, charter schools and vouchers can serve the public good, but in practice, they have not. This shortcoming, however, is not necessarily due to an inherent flaw in charters or vouchers, but the failure of …

Tribute To Professor Calvin William Sharpe, Robert N. Strassfeld

Faculty Publications

The editors of the Case Western Reserve Law Review respectfully dedicate this issue to Professor Calvin William Sharpe.

One can only stand in awe when reflecting on the extraordinary professional accomplishments of Professor Calvin William Sharpe. It is rare in the legal academy to find a professor whose academic range is so broad and whose level of quality is so consistently high. That range and quality are evident regardless of whether one looks at Professor Sharpe's teaching, scholarship, or professional service.

Strain And Counterstrain For Structural Integrators, Caryn Pierce

Faculty Publications

Strain and counterstrain (SCS) is an indirect approach to manipulating fascia. In addition to its usefulness as an integration tool, knowledge of the reflexive mechanisms involved in SCS deepens our understanding of how fascia functions to protect vital structures from injury and how unbalanced posture and movement patterns develop after trauma.

Food Safety Attitudes In College Students: A Structural Equation Modeling Analysis Of A Conceptual Model, Rachelle Booth, Maggie Hernandez, Erica L. Baker, Tevni Grajales, Peter Pribis

Faculty Publications

College students are one of the most at-risk population groups for food poisoning, due to risky food safety behaviors. Using the Likert Scale, undergraduate students were asked to participate in a Food Safety Survey which was completed by 499 students ages 18–25. Data was analyzed using SPSS and AMOS statistical software. Four conceptual definitions regarding food safety were defined as: general food safety, bacterial food safety, produce food safety, and politics associated with food safety. Knowledge seems to be an important factor in shaping students attitudes regarding general and bacterial safety. Ethnicity plays a role in how people view the …

Awakening The Slumbering Giant: How Horizontal Drilling Technology Brought The Endangered Species Act To Bear On Hydraulic Fracturing, Kalyani Robbins

Faculty Publications

Hydraulic fracturing (also known as “fracking”) is nothing new. It dates back to the 1940s and drew little environmental attention or concern for most of its existence. It is a form of natural gas extraction that involves pumping water, chemicals, and sand slurry into a well at extremely high pressure in order to fracture the surrounding rock formation and prop open passages. This frees up the trapped natural gas to flow from the resulting rock fractures to the production well for capture. Fracking operations have evolved from using a range of 20,000 to 80,000 gallons of water per well to …

“I’M Not Quite Dead Yet!”: Rethinking Anti-Lapse Redistribution Of A Dead Beneficiary’S Gift, Eloisa Rodriguez-Dod

Faculty Publications

Anti-lapse statutes create a category of substitute takers when a beneficiary prematurely dies. They are based on the legislature’s presumption of how a testator or settlor would want his property distributed in these circumstances. However, a testator’s or settlor’s intent may effectively be frustrated by this presumed intent.

This Article critically examines the tension between an individual’s autonomy and societal goals in the context of anti-lapse statutes applicable to wills and trusts. It scrutinizes the current rules of construction regarding anti-lapse statutes and identifies their deficiencies in their application to wills and trusts. This Article analyzes and identifies the deficiencies …

Peer Review Across The Curriculum, Patricia G. Montana

Faculty Publications

(Excerpt)

In 2007, two very influential institutes published reports that challenged legal educators to reconsider how they design courses, deliver instruction, assess their students’ learning and explore new ways to prepare students for the profession of law. The Carnegie Foundation for the Advancement of Teaching published its report, Educating Lawyers: Preparation for the Profession of Law (“Carnegie Report”), and the Clinical Legal Education Association published its study, Best Practices for Legal Education (“Best Practices Report”) (collectively, the “Reports”). Both Reports came to the same conclusion: law schools must devote more attention and resources to helping students develop the professional skills …

Disclosure As Distribution, Jeremy N. Sheff

Faculty Publications

This brief response to the work of Professors Omri Ben-Shahr and Carl Schneider on mandated disclosure regimes investigates the normative criteria underlying their claim that those regimes are failures. Specifically, it unpacks the pieces of those authors' implicit cost-benefit analysis, revealing inherently normative judgments about desert and responsibility at the core of their (or any) critique of disclosure regimes. Disclosure regimes may aim to improve human decisionmaking behaviors, but those behaviors are influenced in non-deterministic ways by cognitive capacities that are heterogeneously distributed among subjects of the regimes. Accordingly, any claim regarding the normative desirability of disclosure regimes (or any …

The Causal Context Of Disparate Vote Denial, Janai S. Nelson

Faculty Publications

For nearly fifty years, the Voting Rights Act of 1965 ("VRA") and its amendments have remedied racial discrimination in the electoral process with unparalleled muscularity. Modern vote denial practices that have a disparate impact on minority political participation, however, increasingly fall outside the VRA's ambit. As judicial tolerance of disparate impact claims has waned in other areas of law, the contours of Section 2, one of the VRA's most powerful provisions, have also narrowed to fit the shifting landscape. Section 2's "on account of race" standard to determine discrimination in voting has evolved from one of quasi-intent determined by a …

Family-Focused Physical Activity, Diet, And Obesity Interventions In African-American Girls: A Systematic Review, Daheia J. Barr-Anderson, Alexis W. Adams-Wynn, Katherine I. Disantis, Shiriki Kumanyika

Faculty Publications

Obesity interventions that involve family members may be effective with racial/ethnic minority youth. This review assessed the nature and effectiveness of family involvement in obesity interventions among African-American girls aged 5-18 years, a population group with high rates of obesity. Twenty-six databases were searched between January 2011 and March 2012, yielding 27 obesity pilot or full-length prevention or treatment studies with some degree of family involvement and data specific to African-American girls. Interventions varied in type and level of family involvement, cultural adaptation, delivery format, and behavior change intervention strategies; most targeted parent-child dyads. Some similarities in approach based on …

Robert Julius Trumpler And The Cosmos: The Contributions Of A Swiss American Astronomer, Kurt Winkler

Faculty Publications

Swiss American scientists have made many valuable contributions to a more precise understanding of the universe. Among the most influential of these was the astronomer, Robert Julius Trumpler, who did much to advance our knowledge of the Pleiades star cluster, the planet Mars, globular clusters, and the theories of his fellow Swiss American , Albert Einstein. Trumpler made his contributions at an important time in the development of astronomical theories that more accurately explained the nature of the universe, and his advances are still important today. He is also fondly remembered as one of the most significant astronomers of his …

Learning How To Fish: Catch Shares And The Future Of Fishery Conservation, Jonathan H. Adler, Nathaniel Stewart

Faculty Publications

The hard choices being made in an effort to save the Atlantic cod fishery today are all too common, as policymakers continue to employ and rely upon failed conservation policies, leaving fisheries the world over poorly managed and under stress. By some measures, a majority of exploited fisheries are depleted or in decline. Even more troubling, new research suggests that those fisheries about which scientists know the least may be in the worst shape. Yet all is not lost—perhaps not even for the great Atlantic cod. These same assessments conclude that, with proper management, fishery yields could double while remaining …

Placing "Reins" On Regulations: Assessing The Proposed Reins Act, Jonathan H. Adler

Faculty Publications

Over the past several decades, the scope, reach and cost of federal regulations have increased dramatically, prompting bipartisan calls for regulatory reform. One such proposed reform is the Regulations From the Executive in Need of Scrutiny Act (REINS Act). This proposal aims to restore political accountability to federal regulatory policy decisions by requiring both houses of Congress to approve any proposed “major rule.” In effect, the REINS Act would limit the delegation of regulatory authority to federal agencies, and restore legislative control and accountability to Congress. This article seeks to assess the REINS Act and its likely effects on regulatory …

Mechanical Properties Of Human Amniotic Fluid Stem Cells Using Nanoindentation, Ashkan Aryaei, Ambalangodage Jayasuriya

Faculty Publications

The aim of this study was to obtain nanomechanical properties of living cells focusing on human amniotic fluid stem (hAFS) cell using nanoindentation techniques. We modified the conventional method of atomic force microscopy (AFM) in aqueous environment for cell imaging and indentation to avoid inherent difficulties. Moreover, we determined the elastic modulus of murine osteoblast (OB6) cells and hAFS cells at the nucleus and cytoskeleton using force–displacement curves and Hertz theory. Since OB6 cell line has been widely used, it was selected to validate and compare the obtained results with the previous research studies. As a result, we were able …

Advancing Trauma-Informed Systems Change In A Family Drug Treatment Court Context, Laurie Drabble, Shelby Jones, Vivian Brown

Faculty Publications

A growing body of literature documents the importance of trauma-informed and trauma-specific services and systems change in both addiction treatment and child welfare fields. The overall aim of this qualitative study was to explore barriers, benefits, and facilitating factors associated with a trauma-informed systems assessment and improvement initiative conducted in the context of a family drug treatment court (FDTC). Semistructured in-depth interviews with 12 key informants and historical analyses of project documents over a 4-year time span were conducted. Results underscore the relevance of trauma-informed systems change in collaborative contexts designed to address the complex needs of children and families.
