Abstract

Synthetic Jet (SJ) actuators are an intrinsically complex combination of electronics, electric and mechanical systems. When studied theoretically, these elements are often simplified to coupled damped harmonic oscillators (DHO) that induce a pressure field within the cavity and drive momentum exchange. Thus, the performance of an SJ actuator results from coupling these DHOs, naturally leading to a few resonant modes. There is good evidence in the specialized literature of two resonant modes developing in SJ actuators: the membrane/piezoelectric mode and the Helmholtz resonance. In this work, we report on the effect of a third resonant mode that develops at very low frequencies due to a cavity much larger than the volume displaced by the actuator. We present evidence that the large-cavity dynamics determine the SJ performance in combination with the well-described formation criteria. We compare the intensity of this resonant mode with the first room modes using standard frequency analysis. Unlike typical room modes, the distribution of this resonant mode is very biased to lower frequencies. We also show that the resonant mode may be dimmed and focused by adding an obstacle in different cavity positions for the lower sound intensities. This mode overcomes the Helmholtz resonance, dominating the dynamics for higher sound intensities. We show that jet and vortex velocities mimic the sound pressure curve for the low-frequency range. Its effect mitigates for the higher range due to a delve through smaller stroke lengths, characterized as a fixed relation between the Reynolds and the Stokes numbers. We consider that the large-cavity dynamics is an additional element that, if integrated as design criteria, could extend the optimum frequency response of SJs., Comment: 21 pages, 10 figures, to be submitted

4. A Justice Oriented Examination of Teacher Education through the Lens of Deans' Innovations and Leadership in Schools of Education

Author

Kelly León, Paul M. Rogers, Reyes L. Quezada, and Sobeida Velázquez

Abstract

Social-justice teacher education literature is widespread, but research highlighting the perspectives and insights from those who lead is far less common. This interview-based case-study of 20 deans from the Schools of Education across the United States addresses this gap and explores insights that pertain to the leadership and implementation of teacher education programs that advance social justice and teacher agency. Using conceptualisations of thin and strong equity, we identify, explain, and discuss three themes which emerged from the data. The first involves addressing barriers and access issues for prospective teacher candidates. The second includes programmatic actions taken by deans in attempts to further social justice goals and the third highlights an understanding that social justice work inevitably includes working to change systems and structures at the societal scale. We explore the extent to which these patterns reflect strong equity and provide ideas for deepening this work through the development and reframing of teacher agency.

42. The California Council on Teacher Education: Developing Faculty Leaders in Teacher Education

Author

Quezada, Reyes L.

Abstract

As the 70th California Council on Teacher Education (CCTE) anniversary approaches it is hard for the author to believe that he has been involved with this organization since 1993, twenty-one years. As he reflected on how he was introduced and what kept him involved in the organization in many capacities, the author realized he knows of no other professional organization where such lasting friendships have been developed and nurtured. The author's involvement in CCTE included: two years as President Elect, two as President, and two as Past President, as well as four years as a CCTE Board member, four as CCTE Vice-President for AACTE, and two years as CCTE Vice President of ATE, for a total of sixteen years of in-depth work with CCTE in a leadership capacity. In this article, the author shares his reflections on his own ideas for CCTE, along with the goals that he set and the accomplishments achieved.

Abstract

The BL Lacertae object 1ES 1440+122 was observed in the energy range from 85 GeV to 30 TeV by the VERITAS array of imaging atmospheric Cherenkov telescopes. The observations, taken between 2008 May and 2010 June and totalling 53 hours, resulted in the discovery of $\gamma$-ray emission from the blazar, which has a redshift $z$=0.163. 1ES 1440+122 is detected at a statistical significance of 5.5 standard deviations above the background with an integral flux of (2.8$\pm0.7_{\mathrm{stat}}\pm0.8_{\mathrm{sys}}$) $\times$ 10$^{-12}$ cm$^{-2}$ s$^{-1}$ (1.2\% of the Crab Nebula's flux) above 200 GeV. The measured spectrum is described well by a power law from 0.2 TeV to 1.3 TeV with a photon index of 3.1 $\pm$ 0.4$_{\mathrm{stat}}$ $\pm$ 0.2$_{\mathrm{sys}}$. Quasi-simultaneous multi-wavelength data from the Fermi Large Area Telescope (0.3--300 GeV) and the Swift X-ray Telescope (0.2--10 keV) are additionally used to model the properties of the emission region. A synchrotron self-Compton model produces a good representation of the multi-wavelength data. Adding an external-Compton or a hadronic component also adequately describes the data., Comment: 8 pages, 4 figures. Accepted for publication in MNRAS

Abstract

The very high energy (VHE; E $>$ 100 GeV) blazar Markarian 501 was observed between April 17 and May 5 (MJD 54938--54956), 2009, as part of an extensive multi-wavelength campaign from radio to VHE. Strong VHE $\gamma$-ray activity was detected on May 1st with Whipple and VERITAS, when the flux (E $>$ 400 GeV) increased to 10 times the pre-flare baseline flux ($3.9{\times 10^{-11}}~{\rm ph~cm^{-2}~s^{-1}}$), reaching five times the flux of the Crab Nebula. This coincided with a decrease in the optical polarization and a rotation of the polarization angle by 15$^{\circ}$. This VHE flare showed a fast flux variation with an increase of a factor $\sim$4 in 25 minutes, and a falling time of $\sim$50 minutes. We present the observations of the quiescent state previous to the flare and of the high state after the flare, focusing on the flux and spectral variability from Whipple, VERITAS, Fermi-LAT, RXTE, and Swift combined with optical and radio data., Comment: 13 pages, 10 figures.
