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
High Resolution Forest Maps from Interferometric TanDEM-X and Multitemporal Sentinel-1 SAR Data
No full textIn this study, a workflow for a semi-automated forest/non-forest detection is proposed that is based on multitemporal Sentinel-1 ground range detected (GRD) C-band backscatter and TanDEM-X Coregistered Single look Slant range Complex (CoSSC) X-band imagery and an unsupervised random forest classification approach. Therefore, numerous features that refer to frequency, polarisation, and texture were extracted from SAR data of different seasons. The aim was to develop a processing scheme that is feasible for semi-automated forest mapping and monitoring from SAR data at high spatial resolution and on annual scale. It was tested for seven study sites in Germany and Canada which represent different biomes and forest types. Results were validated against field observations and existing forest maps. The best performance for the German study sites was achieved with multitemporal Sentinel-1 backscatter data from the onset of the growing season with small incidence angle and VH polarisation, together with extracted textural features and TanDEM-X data. Producer’s accuracies for the forest class of the different study sites ranged from 88.4 to 98.0%. User’s accuracies ranged from 85.5 to 87.0%. Using Sentinel-1 data covering the whole growing season at a 12 day repetition rate, ascending and descending orbits and VV and VH polarisations led to comparable results. Limited data availability for the Canadian study sites resulted in on average to less reliable results than at the German sites with a higher range of producer’s (62.4–98.8%) and user’s accuracies (46.2–90.2%)

Daniel Akech
No full textabstract: Daniel was a little boy when the war came to his village. He witnessed people being shot and running for shelter. There was no food or water so he drank urine and ate tree leaves.
“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
