Study of the lepton flavor violating decays of the Higgs boson at the ATLAS experiment
No full textTitle: Study of the Lepton Flavor Violating Decays of the Higgs Boson at the ATLAS Experiment Author: Petr Kouba Institute: Institute of Particle and Nuclear Physics Supervisor: Mgr. Daniel Scheirich, Ph.D., Institute of Particle and Nuclear Physics Abstract: The thesis contains an analysis of the potential lepton flavor violating Higgs boson decays performed on the data acquired by the ATLAS experiment during the Run II period of the LHC. The analysis comprised of an event selection aiming at the reduction of the backgrounds, while keeping the highest possible amount of the signal events. An estimate of the leptons misidentified by the reconstruction algorithms of the ATLAS experiment was included in the anal- ysis. For the selected events, invariant mass was reconstructed in the collinear approximation. The distribution of the invariant mass according to the MMC was provided for reference purposes. Keywords: Higgs boson, ATLAS, collinear approximation i

Daniel Scheirich, Ph.D., Ústav částicové a jaderné fyziky Abstrakt: Práce obsahuje analýzu potenciálních rozpadů Higgsova bosonu naru- šujících leptonové číslo, vykonanou na datech z experimentu ATLAS pořízených během periody RUN2 na urychlovači LHC. Analýza sestávala z výběru eventů, cíleného na potlačení pozadí a současného zachování nejvyššího možného počtu signálních eventů. Do analýzy byl zahrnut i odhad leptonů, chybně identifiko- vaných rekonstrukčími algoritmy experimentu ATLAS. Pro vybrané eventy byla zrekonstruována invariantní hmota v kolineární aproximací. Pro porovnání je uvedeno i rozdělení invariantní hmoty dle metody MMC. Klíčová slova: Higgsův boson, ATLAS, kolineární aproximace 23Title: Study of the Lepton Flavor Violating Decays of the Higgs Boson at the ATLAS Experiment Author: Petr Kouba Institute: Institute of Particle and Nuclear Physics Supervisor: Mgr.

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
(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

“Lost Boys Found” is an ongoing, interdisciplinary project that is collecting, recording and archiving the oral histories of the Lost Boys/Girls of Sudan. The collection is a work-in-progress, seeking to record the oral history of as many Lost Boys/Girls as are willing, and will be used in a future book.Age: 24Region: Upper NileThis picture and bio was donated to the "Lost Boys Found" oral history project from The Arizona Lost Boys Cente
Daniel Emmett postcard
No full textPostcard of Daniel Emmett and his home in Mount Vernon, Ohio. Emmett is considered to be the author of the antebellum song "Dixie," written in 1859, which became the unofficial song of the Confederate soldiers during the American Civil War. He was born in Mount Vernon in 1815 and taught himself the fiddle, and later became associated with minstrel shows and helped to define that genre. Minstrel shows traveled around the United States, presenting skits and musical performances. Emmett also composed many other songs, including "Old Dan Tucker," "Turkey in the Straw," and "The Blue Tail Fly." He died in 1904
