In this paper, a framework for obtaining the higher order derivative of digital signals with an improved signal-to-quantization-noise ratio (SQNR) is developed. The framework consists of an oversampling analog-to-digital conversion unit with a dithering process and a higher order finite-impulse response (FIR) digital differentiator followed by a decimator. A simple and effective recursion is derived for designing the higher order FIR digital differentiator. In addition, the SQNR is analyzed. Computer simulations validate the proposed framework, the differentiator design method, and the results of the improved SQNR. © 2011 IEEE.

This paper examines the short-run and long-run dynamic relationship between the U.S. imported crude oil prices and exchange rates. The monthly data of the U.S. crude oil imports from five source countries during January 1996 and December 2009 are examined. Empirical results indicate that the exchange rates Granger-caused crude oil prices in the short run while the crude oil prices Granger-caused the exchange rates in the long run. Furthermore, oil prices were affected by the exchange rate changes at a minimal level. However, in the medium run and the long run, oil price shocks had a significant impact on exchange rate changes. Exchange rate shock has a significant negative impact on crude oil prices while the impulse response of the exchange rate variable to a crude oil price shock was statistically insignificant. Finally, the impact of extreme price volatility in June 2008 on exchange rates was significant. When world oil prices are stabilized, currency fluctuations and uncertainty can be minimized. © 2014 Elsevier B.V.

We propose a model for the incorporation of 10Be within calcium-aluminum inclusions (CAIs) in primitive carbonaceous meteorites. In this model, 10Be is produced by energetic particle reactions in the proto-solar atmosphere of a more active proto-Sun characterized by energetic particle fluxes higher than contemporary particle fluxes. This 10Be is incorporated into the solar wind that is then implanted into CAI precursor material. This production mechanism is operational in the contemporary solar system implanting 10Be in lunar materials. The contemporary production rate of 10Be at the surface of the Sun is ∼0.1 10Be cm-2 s-1. Scaling up the contemporary 10Be production in the proto- Sun by a factor of 105 would increase the production rate to 104 10Be cm-2 s-1. Using this enhanced production value in conjunction with refractory mass inflow rates at 0.06 AU from the proto-Sun we model 10Be concentrations in CAI precursors. We calculate the content of solar-wind-implanted 10Be would have been of the order of 1012 10Be g-1 in CAIs, consistent with initial10Be content found from boron-beryllium isotopic systematics in CAIs. © 2010.

The current longitudinal, descriptive, and correlational study explored which traditional teaching strategies can engage Millennial students and adequately prepare them for the ultimate test of nursing competence: the National Council Licensure Examination. The study comprised a convenience sample of 40 baccalaureate nursing students enrolled in a psychiatric nursing course. The students were exposed to a variety of traditional (e.g., PowerPoint®-guided lectures) and nontraditional (e.g., concept maps, group activities) teaching and learning strategies, and rated their effectiveness. The students’ scores on the final examination demonstrated that student learning outcomes met or exceeded national benchmarks. © SLACK Incorporated.

This paper presents pedagogies and experiences for teaching digital signal processing (DSP) with real-time processing experiences in the electrical and computer engineering technology (ECET) program using a digital crossover system. In our ECET curriculum, the engineering technology students often face their challenging in studying the signal processing related courses due to the use of heavy mathematics. Although adopting MATLAB as an analysis and simulation tool is a great help, the engineering technology students are especially motivated by their real-time processing learning experiences. To accommodate such a learning environment, our DSP course with laboratories has been improved, in which each lab concurrently requires MATLAB simulations as well as real-time processing coding with a digital signal processor such as Texas Instruments' TMS320C6713 DSK. This DSP course is the second signal processing course in electrical and computer engineering technology (ECET) program. The pre-requisite includes student working knowledge and skills of Laplace transform, Fourier series, Fourier transform, and different types of analog active filter design. After completing the course, students not only become familiar with MATLAB software development tools, but also gain the real-time analog signal processing experience. In this class, they learn to design digital low-pass, high-pass and band-pass filters and then program them using MATLAB and C, and apply the software and hardware interface for real speech applications such as in a crossover system. Comparing with the traditional DSP course which mainly focus on heavy mathematical development in sampling and recovering, spectrum analysis, FIR or IIR filter design with the limited computer simulations, our real-time crossover project allows students easily understand how a speech signal or music being processed and separated by a bass (woofer) and a tweeter after they design the proper low-pass and high-pass filters and apply two DSP boards (TI TMS320C6713 DSK). Therefore, in this paper, we first present a complete digital crossover platform, MATLAB design and simulations, developed C code inserted in both of DSP boards, crossover outputs and test results. Secondly, we address the outcomes of students learning achievement including continuous applications of their acquired DSP skills in other related courses and their motivations for continuing to pursue the upper-level signal processing related courses such as the advanced digital signal processing with multimedia applications. More importantly, we examine the course assessment according to analysis of the collected data from students' learning outcome survey, project evaluation, and further address the possible improvements of the course content based on our assessment. © American Society for Engineering Education, 2014.

Students often make mistakes in physics courses and are expected to identify, correct, and learn from their mistakes, usually with some assistance from an instructor, textbook, or fellow students. This aid may come in many forms, such as problem solutions that are given to a class, tutoring to an individual student, or a peer discussion among several students. However, in each case a student relies upon an external agent in order to determine whether, and how, her work is mistaken. Consequently, the student's learning process is largely contingent upon the availability and quality of external evaluating agents. One may suspect that if a student developed the ability to evaluate her own work, her dependence on external agents could be moderated and result in an enhancement of her learning. This paper presents the results of a study investigating the impact of novel activities that aim to teach students when, why, and how to use the strategies of unit analysis and special-case analysis. The data indicate that it is possible to help students dramatically improve their under- standing of each strategy, and that this has a significant impact on problem-solving performance.© 2010 The American Physical Society.

For decades, sociological theory has documented how our lives are simultaneously produced through and against normative structures of sex, gender, and sexuality. These normative structures are often believed to operate along presumably “natural,” biological, and essentialized binaries of male/female, man/woman, and heterosexual/homosexual. However, as the lives and experiences of transgender people and their families become increasingly socially visible, these normative structuring binaries are called into stark question as they fail to adequately articulate and encompass these social actors’ identities and social group memberships. Utilizing in-depth interviews with 50 women from the United States, Canada, and Australia, who detail 61 unique relationships with transgender men, this study considers how the experiences of these queer social actors hold the potential to rattle the very foundations upon which normative binaries rest, highlighting the increasingly blurry intersections, tensions, and overlaps between sex, gender, and sexual orientation in the 21st century. This work also considers the potential for these normative disruptions to engender opportunities for social collaboration, solidarity, and transformation. © 2014 by The University of Chicago.

Structural health monitoring (SHM) is emerging as a vital tool to help civil engineers improve the safety, maintainability, and reliability of critical structures and assists infrastructure owners with timely information for the continued safe and economic operation of their structure. SHM involves implementing a strategy that identifies and characterizes damage or undesirable performance in engineering structures. The goal of this research project was to determine the smallest strains measurable using standard digital image correlation (DIC) based SHM equipment. This practical investigation that had strong ties to the industry was motivated by damage observed in a real-world bridge, which was initially undetected. Its early detection would have led to reduced repair costs. To accomplish the aforementioned goal, tests were performed on a laboratory specimen that replicated a steel beam-to-column connection of the concerned bridge, involving progressively loading it in a manner in which it was loaded in the actual bridge, while simultaneously measuring the strains that developed in it using the aforementioned DIC-based equipment and software. Under the controlled conditions in the laboratory, the minimum resolution of the state-of-the-art system used in this investigation was determined. Due to the challenges faced in making these small-strain measurements even under highly controlled laboratory conditions, it was concluded that it is currently unrealistic to use the existing DIC technology in a real-world situation to measure strains as small as those that would need to be measured to detect the onset of damage in bridge connections. More work needs to be done in this area. © 2016 SPIE.

A 45 MHz benchtop NMR spectrometer is used to identify the structures and determine the amount of 1-bromoethylbenzene and 1,1-dibromoethylbenzene produced from free-radical bromination of ethylbenzene. The experiment is designed for nonchemistry majors, specifically B.S. Biology students, in a predominantly undergraduate institution with insufficient resources for the initial cost and maintenance of high-field Fourier transform (FT) NMR instrumentation. Students learn the basic concepts of nuclear magnetic resonance, acquire FID (free-induction decay) signals, process the data, interpret, assign peaks, and determine product composition. The experiment demonstrates to students that NMR spectroscopy can be used for molecular structure characterization and for determination of product yields. Hands-on experience with a low-field spectrometer provides undergraduate students with confidence to run an NMR instrument while minimizing fear that can be generated at the sight of high field FT-NMR instrumentation. © 2014 The American Chemical Society and Division of Chemical Education, Inc.
