The Effect of Winding Curvature and Core Permeability on the Power Losses and Leakage Inductance of High-Frequency Transformers
No full textAt the frequencies used in switching dc-dc converters, the skin and proximity effects have a significant effect on both the losses and leakage inductance of the transformers used in these circuits. Analytical expressions that have been derived to calculate ac resistance and leakage inductance have primarily used a 1-D approximation. They also have used Cartesian coordinates or approximations that are equivalent to Cartesian coordinates, as well as usually assuming an ideal core of infinite permeability. The classical result in the case of the resistance/losses is Dowell’s equation, and there are analogous results for leakage inductance. This dissertation derives new equations that take the effect of winding curvature into account by using cylindrical coordinates. These equations are also more general in that they permit any interleaving pattern as well as variable layer thicknesses and gaps between layers. Additionally, new equations for the magnetic field coefficients are derived that take the core permeability into account, which requires a full 2-D model and the method of images applied in two dimensions. These coefficients then allow calculations of resistance/losses and leakage inductance that also take the core permeability and winding width into account. The accuracy of all of these equations is assessed by comparing their results with those of finite-element analysis (FEA) simulations. Due to the large number of parameters involved with the fully general equations, a statistical approach is used in which a large number of randomly generated devices are simulated. Finally, for a special class of more specific transformers, the effects of a reduced number of independent parameters on the resistance/losses and leakage inductance is determined empirically. The relative sensitivity of these quantities on these parameters is also determined
Report on Meteorological Research March 1, 1935 (m-1)
No full textThe object of the report was to elucidate in detail the various features of the research program in meteorology being carried on at the Daniel Guggenheim Airship Institute in Akron, Ohio. Mr. L. J. Fangman, of the U.S. Weather Bureau, was collaborating with the author in carrying out work such as a study of autographic records of the various meteorological elements during frontal passages with a view to the possible prediction of the intensity of the accompanying disturbance as it may affect the operation of aircraft and a study of atmospheric gustiness with a view to finding the dependence between frequency end amplitude of velocity fluctuations and the vertical temperature and velocity gradients
The King is Always Above the People
No full textA slyly political collection of stories about immigration, broken dreams, Los Angeles gang members, Latin American families, and other tales of high stakes journeys, from the award-winning author of War by Candlelight and At Night We Walk in Circles. Migration. Betrayal. Family secrets. Doomed love. Uncertain futures. In Daniel Alarcon\u27s hands, these are transformed into deeply human stories with high stakes. In The Thousands, people are on the move and forging new paths; hope and heartbreak abound. A man deals with the fallout of his blind relatives\u27 mysterious deaths and his father\u27s mental breakdown and incarceration in The Bridge. A gang member discovers a way to forgiveness and redemption through the haze of violence and trauma in The Ballad of Rocky Rontal. And in the tour de force novella, The Auroras , a man severs himself from his old life and seeks to make a new one in a new city, only to find himself seduced and controlled by a powerful woman. Richly drawn, full of unforgettable characters, The King is Always Above the People reveals experiences both unsettling and unknown, and yet eerily familiar in this new worldhttps://corescholar.libraries.wright.edu/dlpp_all/1519/thumbnail.jp
Daniel Hernandez - First Responder for Congresswoman Gabrielle Giffords
No full textHow Student Advocacy and Activism Helped Me Give to My Community
Daniel Hernandez was a congressional intern for Rep. Gabrielle Giffords of Arizona\u27s eighth congressional district when, on January 8, 2011, the congresswoman was shot along with 18 others by a gunman at a Tucson constituent event. Hernandez sprang into action, and his medical training, quick thinking, and brave actions on that day have been widely credited with saving Giffords\u27 life.
Many now celebrate Hernandez as a true American hero, though he humbly rejects that title. Still, he was an honored guest of the President and First Lady during the 2011 State of the Union address, and he addressed President Obama and a crowd of more than 27,000 people and nearly 500 media outlets at the Tucson: Together We Thrive memorial on January 12, 2011.
Daniel has conducted more than 500 media interviews in English and Spanish with local, state, national, and international outlets, with appearances on the three major TV networks and on MSNBC\u27s Rachel Maddow Show, The Fox Report, and Univision\u27s Al Punto.
The 21-year-old Tucson native is a student at the University of Arizona studying political science. Hernandez is dedicated to student advocacy and political activism. He served as a director on the Arizona Students\u27 Association\u27s Board of Directors and advocated for affordable and accessible higher education for all Arizonans. He began his political activism in 2007 working on the Hillary Clinton presidential campaign, and in Giffords\u27 2008 congressional campaign. He has also served on the City of Tucson Commission on GLBT (Gay, Lesbian, Bisexual, and Transgender) issues.https://corescholar.libraries.wright.edu/archives_presidential_lecture_series/1022/thumbnail.jp
(Fourth) Report on Meteorological Activities at the DGAI (8-1-36)(Weather Bureau Copy)
No full textThis report is on the investigations of frontal phenomena at the Daniel Guggenheim Airship Institute in Akron, Ohio from January 1, 1935 through August 1, 1936. The investigation was carried out with the cooperation of the U.S. Bureau of Aeronautics, the U.S. Weather Bureau, the California Institute of Technology, and the Guggenheim Airship Institute. Mr. R.C. Robinson of the Weather Bureau cooperated with the author in carrying out the investigation. The object of the investigation was to determine the intensity of the atmospheric disturbances (i.e. rapidity of wind shift and gustiness) accompanying the passage of cold fronts, along with a study of the characteristics of the air masses involved and other features which might affect the intensity of the disturbance. The report treated thirty cold fronts which passed the station during 1935 to 1936
