Chapter 10 Introduction to Presentation Applications
No full textA presentation is an electronic document that conveys information to an audience. Robert Gaskins got the idea of software to create “slides of text and graphics in a graphical, WYSIWYG environment, then outputting them to 35-mm slides, overhead transparencies, or video displays and projectors... [t]he presentation would spring directly from the mind of the business user, without having to first transit through the corporate art department.” Before working on PowerPoint, as a student Gaskins had worked in the computer lab at Berkeley as a graphics consultant. Gaskins began working on the software, initially called Presenter, in July 1984, and continued working on it with two colleagues, Dennis Austin and Tom Rudkin, and released PowerPoint on April 20, 1987, for Mac computers. Three months later, in July 1987, Microsoft bought their company, Forethought Inc, for $14 million. 5 years later in 1992, Microsoft released PowerPoint 3.0, which in Gaskins’ words, realized his initial vision for the product. The first public presentation from a laptop to project video from PowerPoint took place on February 25, 1992, in Paris. Since then, presentation software is used at virtually all business meetings to improve communication. Students use presentation software in a variety of creative ways to create flyers, brochures, and other electronic documents
Application of Deep Learning Approaches to Predict Monthly Stream Flows
No full textAccurate and reliable flow estimations are of great importance for hydroelectric power generation, flood and drought risk management, and the effective use of water resources. This research carries out a comprehensive study on the application of gated recurrent unit (GRU) neural network, recurrent neural network (RNN), and long short-term memory (LSTM) to predict with river flows at three different streamflow observation stations in Erzincan, Bayburt, and Gümüshane. Monthly streamflow time series covering the years 1978 to 2015 were used to set up artificial intelligence models. During the modeling phase, 70% of the data was divided into training (October 1978–April 2004), 15% validation (May 2004–September 2009), and 15% test set (October 2010–September 2015). Model performances were made according to the correlation coefficient, root mean square error, the ratio of RMSE to the standard deviation, Nash–Sutcliffe efficiency coefficient, index of agreement, and volumetric efficiency values. The calculation results show that GRU leads efficient estimation results for estimating streamflow and can also be used in allied water resources

The Modernization of Digital Information Technology
No full textThis project titled, “The Modernization of Digital Information Technology” includes a significant collaboration of program support staff, academic faculty, and consultants from the University of South Florida, Hillsborough and Pinellas County public schools, and industry subject matter experts. The focus of this collaborative project is to provide freely available and accessible resources to teachers and students throughout the State of Florida public school system that are required to execute the Florida Department of Education student performance standards curriculum for Digital Information Technology (DIT) (8207310). Additionally, the content included in this project is useful for any 8th – 12th grade course which requires foundational knowledge in digital information technology topics. These resources include products such as a DIT textbook, Canvas course, comic book, and a variety of multi-media instructional content. Teaching resources such as lesson plans and student activities are included. Content included in the student resources will be made freely available for download in both English and in some cases Spanish. Additionally, digital resources have been carefully designed to assist students with some disabilities.https://digitalcommons.usf.edu/oa_textbooks/1013/thumbnail.jp
COVID-19 and the “most magical place on earth”: Applying the IDEA model to theme park crisis messaging
No full textThe global tourism reaches of Orlando, Florida, and the world’s most visited theme park complex, Walt Disney World, provide a unique context for studying global communication in a tourism setting through the crisis messaging efforts. This study explores the reopening of Walt Disney World and subsequent messaging, specifically from a risk and crisis perspective, using the IDEA model to categorize Disney COVID-19 messages. Using a qualitative, etic approach via a codebook based on the IDEA model, the study results determined whether pandemic messages and mentions (the study’s unit of analysis) addressed internalization, explanation, or action
GNSI Decision Brief: What Keeps the US in the Middle East?
No full textIn early August the United States sent “More than 3,000 Marines and Sailors [to the Middle East] in a deployment meant to deter Iran from seizing and harassing merchant ships near the Strait of Hormuz.” The decision likely caught many off guard, considering that just two years prior, the US had finalized its troop withdrawal from Afghanistan. Yet, this isn\u27t the first instance of the United States oscillating in its engagement with the Middle East. Historically, a range of factors have consistently drawn America into the region. The US had minimal involvement in the Middle East until the compounding interests of oil, great power competition, fighting terrorism, and the resource needs of allies fully engaged it.https://digitalcommons.usf.edu/gnsi_decision_briefs/1005/thumbnail.jp

Paleokarst coastal caves at Torricelle Hills (Lessini Mountains, Venetian Prealps, Italy)
No full textThis paper describes a set of paleokarst caves at Torricelle Hills near Verona (Southern Alps, Italy.) At this locality, erosional surfaces and paleokarst cavities show that sedimentation of late Paleogene neritic limestones was interrupted by subaerial exposure. Karst features developed during a phase of marine regression that started after the early Oligocene and ended in the mid Miocene. These caves were originally completely filled by iron oxides- and hydrated oxides-rich paleosol sediments (ochre) that, for centuries, have been mined for pigments. Mining activity emptied the caves, leaving the voids and related shapes mostly intact; as a result, the original morphologies have been exhumed, making these caves a rare example of explorable paleokarst. These “ochre caves” were mapped in a series of surveys over a few years. The exploration of overall 4.5 km of accessible passages in four caves yielded a wealth of information on speleological features, stratigraphy, paleontology, and paleogeography, and here we exploit this information to infer the genesis of these unusual caves. Their evolution started in phreatic conditions, characterized by very slowly moving or still waters that led to the formation of solution facets. A vadose phase of development ensued, followed by infilling by reworked soil-derived sediment and associated paragenetic modifications. Sediment accumulation ended with the complete fossilization of the caves under epiphreatic conditions. Siliciclastic and carbonate sediments containing littoral fossils indicate that the caves developed in the vicinity of a coast, and that they were subject to marine ingression. Overall, these paleokarst coastal caves seem to be a fossilized example, well preserved and explorable, of the Carbonate Island Karst Model on larger islands. We interpret these caves as conduits that drained the freshwater lens in a spatially limited carbonate peninsula that existed in this part of the Lessini paleocoastline between the Oligocene and the Miocene
Design, Fabrication, and Characterization of a Microgripper Device
No full textIn this work, we present the development process of SU-8 polymer based microgrippers applied to novel parallel displacement geometry and assembly techniques. Finite element based simulations were utilized to determine the geometry dimensions, and to verify its operation. Two actuation techniques, mechanical, and piezoelectric are implemented, and characterized. The fabrication process requires a single mask, and it is described along with the assembly process required to implement the actuator-microgripper system. Experimental results are presented for both actuation techniques, along with failure analysis. The microgrippers are designed to manipulate microstructures in the range of 5 to 50μm
