Teaching An Electrical Circuits Course Using A Virtual Lab, Md Zahidur Rahman
Teaching An Electrical Circuits Course Using A Virtual Lab, Md Zahidur Rahman
Publications and Research
This paper describes designing and implementing a scholarship of teaching and learning (SoTL) study in a basic electrical circuits course at LaGuardia Community College. Inspired by my understanding of Shulmans (2005) concept of signature pedagogy and Mazurs (2009) emphasis on student-centered approaches, and aware that our students did not always understand the electrical theory concepts presented in class, I decided to change my pedagogy. We explain our efforts to train our students to think as engineers, first by making them more visible and accountable in the classroom, and second, by offering them hands-on practice through the use of Multisim, a …

Students’ Attitudes About Peer-Led Team Learning Workshops In General Chemistry: A Critical Incident Study, A.E. Dreyfuss, Janet Liou-Mark
Students’ Attitudes About Peer-Led Team Learning Workshops In General Chemistry: A Critical Incident Study, A.E. Dreyfuss, Janet Liou-Mark
Publications and Research
How would students respond to open-ended questions regarding their experiences with PLTL workshops? This paper will present the results of a two-semester qualitative study on how students view workshop in their introductory chemistry courses, using Brookfield’s (1995) Critical Incident Questionnaire (CIQ). The five questions probe what stands out in the affirmative and negative, using key words: engaged, distanced, affirmed, puzzled or confused, and surprising. Collecting key moments from students in workshop, after several weeks of meeting, allow a grounded sense of how students view the workshop experience.
Evolutionary Algorithm Based Approach For Modeling Autonomously Trading Agents, Anil Yaman, Stephen Lucci, Izidor Gertner
Evolutionary Algorithm Based Approach For Modeling Autonomously Trading Agents, Anil Yaman, Stephen Lucci, Izidor Gertner
Publications and Research
The autonomously trading agents described in this paper produce a decision to act such as: buy, sell or hold, based on the input data. In this work, we have simulated autonomously trading agents using the Echo State Network (ESNs) model. We generate a collection of trading agents that use different trading strategies using Evolutionary Programming (EP). The agents are tested on EUR/ USD real market data. The main goal of this study is to test the overall performance of this collection of agents when they are active simultaneously. Simulation results show that using different agents concurrently outperform a single agent …
Algebraic Formulation Of Hadronic Supersymmetry Based On Octonions: New Mass Formulas And Further Applications, Sultan Catto, Yasemin Gürcan, Amish Khalfan, Levent Kurt
Algebraic Formulation Of Hadronic Supersymmetry Based On Octonions: New Mass Formulas And Further Applications, Sultan Catto, Yasemin Gürcan, Amish Khalfan, Levent Kurt
Publications and Research
A special treatment based on the highest division algebra, that of octonions and their split algebraic formulation is developed for the description of diquark states made up of two quark pairs. We describe symmetry properties of mesons and baryons through such formulation and derive mass formulae relating π, ρ, N and Δ trajectories showing an incredible agreement with experiments. We also comment on formation of diquark-antidiquark as well as pentaquark states and point the way toward applications into multiquark formulations expected to be seen at upcoming CERN experiments. A discussion on relationship of our work to flux bag models, string …
Generalized Least-Squares Regressions Iii: Further Theory And Classification, Nataniel Greene
Generalized Least-Squares Regressions Iii: Further Theory And Classification, Nataniel Greene
Publications and Research
This paper continues the work of this series with two results. The first is an exponential equivalence theorem which states that every generalized least-squares regression line can be generated by an equivalent exponential regression. It follows that every generalized least-squares line has an effective normalized exponential parameter between 0 and 1 which classifies the line on the spectrum between ordinary least-squares and the extremal line for a given set of data. The second result is the presentation of fundamental formulas for the generalized least-squares slope and y-intercept.

Finite Element Spectral Approximation With Numerical Integration For The Biharmonic Eigenvalue Problem, Max Tran
Publications and Research
We investigate the convergence properties of a mixed finite element method approximation to the Biharmonic eigenvalue problem under the presence of numerical integration. We give a brief overview of the results obtained when exact integration is used in a finite element method, then develop related theories and obtained the convergence rates when numerical quadrature is taken into account. The standard approach to obtaining error estimate of variational eigenvalue problems is based on the error estimate of the solution operators of the source problems. The important issues are the rate of convergence of the solution operators and the conditions required for …

The results indicate that a central core supporting a national experiment can help overcome local obstacles.
Chemistry Students’ Attitudes About Peer-Led Team Learning Workshops: Comparison To The Six Critical Components, A.E. Dreyfuss, Janet Liou-Mark, Leo Gafney
Chemistry Students’ Attitudes About Peer-Led Team Learning Workshops: Comparison To The Six Critical Components, A.E. Dreyfuss, Janet Liou-Mark, Leo Gafney
Publications and Research
While tracking students’ performance and perseverance is important to determine the effect of the incorporation of workshops in courses, little has been published on students’ attitudes toward workshops: How do students feel about PLTL workshops? One method of examining this question is through a questionnaire developed by Gafney. This paper will present the results of a three-semester study using this questionnaire on how students view workshop in their introductory chemistry courses.
Sensitivity Of Orbiting Jem-Euso To Large-Scale Cosmic-Ray Anisotropies, Peter B. Denton, Luis A. Anchordoqui, Andreas A. Berlind, Matthew Richardson, Thomas J. Weiler
Sensitivity Of Orbiting Jem-Euso To Large-Scale Cosmic-Ray Anisotropies, Peter B. Denton, Luis A. Anchordoqui, Andreas A. Berlind, Matthew Richardson, Thomas J. Weiler
Publications and Research
The two main advantages of space-based observation of extreme-energy (& 1019 eV) cosmic-rays (EECRs) over ground-based observatories are the increased field of view, and the all- sky coverage with nearly uniform systematics of an orbiting observatory. The former guarantees increased statistics, whereas the latter enables a partitioning of the sky into spherical harmonics. We have begun an investigation, using the spherical harmonic technique, of the reach of JEM- EUSO into potential anisotropies in the extreme-energy cosmic-ray sky-map. The technique is explained here, and simulations are presented. The discovery of anisotropies would help to identify the long-sought origin of EECRs.

Teaching Standards In Environmental Site Assessments, Angelo Lampousis
Publications and Research
Since 2010, the Department of Earth and Atmospheric Sciences of City College of New York (CCNY) has successfully implemented a two-semester sequence course entitled Phase I and Phase II Environmental Site Assessments. From the very beginning of this effort, a total of ten standards per semester were used as mandatory reference material. Based on this experience, several practical ideas emerge as successful means of integrating standards into an academic curriculum.
Relativistic Particle And Relativistic Fluids: Magnetic Moment And Spin-Orbit Interactions, V. Parameswaran Nair, Dimitra Karabali
Relativistic Particle And Relativistic Fluids: Magnetic Moment And Spin-Orbit Interactions, V. Parameswaran Nair, Dimitra Karabali
Publications and Research
We consider relativistic charged particle dynamics and relativistic magnetohydrodynamics using symplectic structures and actions given in terms of co-adjoint orbits of the Poincare group. The particle case is meant to clarify some points such as how minimal coupling (as defined in text) leads to a gyromagnetic ratio g = 2, and to set the stage for fluid dynamics. The general group-theoretic framework is further explained and is then used to set up Abelian magnetohydrodynamics including spin effects. An interesting new physical effect is precession of spin density induced by gradients in pressure and energy density. The Euler equation (the dynamics …
Terminal Summation: Extending The Concept Of Convergence, Max Tran, Ayalur Krishnan
Terminal Summation: Extending The Concept Of Convergence, Max Tran, Ayalur Krishnan
Publications and Research
This paper presents an atypical method for summing divergent series, and provides a sum for the divergent series log(n). We use an idea of T.E. Phipps, called Terminal Summation, which uses asymptotic analysis to assign a value to divergent series. The method associates a series to an appropriate difference equations having boundary conditions at infinity, and solves the difference equations which then provide a value for the original series. We point out connections between Phipps' method, the Euler-MacLaurin sum formula, the Ramanujan sum and other traditional methods for summing divergent series.

Publications and Research
A cross-sectional survey was administered to Latino and White residents of Omaha, NE, to assess perception of the childhood obesity problem, attribution of responsibility, and support for obesity-related policies. The sample included 40.8% () Latinos and 59.2% () Whites. Among Latinos, 25% did not see childhood obesity as a problem, compared to 6% of Whites (). This difference persisted after adjusting for age, gender, and education level (odds ratio (OR) 2.10, 95% confidence interval (CI) 1.07–4.14). Latinos were more likely to agree that government was responsible for addressing childhood obesity compared to Whites (OR 2.81, 95% CI 1.82–4.35). Higher support …
Technology And Wonder In Thirteenth-Century Iberia And Beyond, Christopher B. Swift
Technology And Wonder In Thirteenth-Century Iberia And Beyond, Christopher B. Swift
Publications and Research
As the desire for affective experiences of the sacred increased in communities across Europe in the late Middle Ages, the Christian faithful crafted lifelike, mechanized figures of Christ, the Virgin Mary, and saints for use in religious festivals. Although each devotional culture evidences unique body/object relationships and meanings, in general animated ritual objects encouraged lay participation in the celebration of saints and the Passion by engaging the senses, and, consequently, an emotional sense of God. In this essay I investigate the ritual alliances between moveable, prop-like saints and their Iberian devotees, in particular the performative meanings that arose from encounters …

Spatial Gaussian Markov Random Fields: Modelling, Applications And Efficient Computations, Yu Ryan Yue, Xiao-Feng Wang
Publications and Research
A powerful modelling tool for spatial data is the framework of Gaussian Markov random fields (GMRFs), which are discrete domain Gaussian random fields equipped with a Markov property. GMRFs allow us to combine the analytical results for the Gaussian distribution as well as Markov properties, thus allow for the development of computationally efficient algorithms. Here we briefly review popular spatial GMRFs, show how to construct them, and outline their recent developments and possible future work.

An African-Centered Approach To Land Education, Salvotore Engel-Dimauro, Karanja Keita Carroll
Publications and Research
Approaches to environmental education which are engaging with place and critical pedagogy have not yet broadly engaged with the African world and insights from Africana Studies and Geography. An African-centered approach facilitates people's reconnection to places and ecosystems in ways that do not reduce places to objects of conquest and things to be exploited for profitability and individual gain. Such an approach offers effective critiques of settler coloniser perspectives on the environment and deeper understandings of the relationship between worldview and ecologically sensitised education. Through examples from Africana Studies and Geography, this article provides an introduction to how an African-centered …

Broadening Our Lenses Of Perception To Advance Learning: An Introduction To Multilectics, Gene Fellner
Broadening Our Lenses Of Perception To Advance Learning: An Introduction To Multilectics, Gene Fellner
Publications and Research
In Broadening our lenses of perception, I address the need to assess students through multiple lenses rather than through the dominant lens of standardized tests. I propose what I call multilectical lenses to provide multidimensional pictures of poor students of color; these highlight student skills and knowledge that tests disregard. Multilectics employs multi level analysis, sound and images to analyze the gestures and voices of students during classroom activities. In combination with student writing, the data produced by multilectical practice provide a rich foundation for advancing the academic achievement of our most underserved students.
