Manufacturing of glass-fiber-reinforced dicyclopentadiene-matrix composites via frontal polymerization
No full textThe student, Sagar Ketan Vyas, accepted the attached license on 2020-03-05 at 10:28.A homogenized reaction-diffusion model is used to study the mechanism of frontal polymerization in glass-fiber-reinforced dicyclopentadiene-matrix composites by studying the effects of the material properties of the reinforcing phase on the velocity, temperature, and width of the reaction front. This model is also nondimensionalized and expressed in a general form in terms of two nondimensional parameters dependent on the material properties and cure kinetics of the composite system. The general nature of this formulation is exploited to generate a large dataset of reaction front velocities for resin chemistries that are similar to dicyclopentadiene (DCPD), which serves as the reference resin in this work. Finally, the homogenized reaction-diffusion model is used to investigate the temperature spike that occurs when two reaction fronts merge. A method to estimate the energy associated with the thermal spike is developed and applied to size a metal heat sink introduced to eliminate the thermal spike.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-05-01The student, Sagar Ketan Vyas, submitted this Thesis for approval on 2020-03-05 at 11:12.This Thesis was approved for publication on 2020-03-09 at 16:11.DSpace SAF Submission Ingestion Package generated from Vireo submission #14886 on 2020-08-25 at 17:26:55Made available in DSpace on 2020-08-26T23:51:24Z (GMT).

Implementation of a one-dimensional hydrodynamic model for the Middle Paraguay River Basin
No full textA steady 1D hydraulic model (HEC-RAS) was implemented for the Middle Paraguay River Basin (MPRB), which comprises a reach between Porto Murtinho, Brazil, and Asunción, Paraguay. In order to prepare the model, first the topo-bathymetry was prepared by digitizing more than 10,000 depth points from available nautical charts and scaling them to a consistent geographic reference system. The main features such as the cross sections, river reach length, flow path and ineffective flow areas were created with the aid of HEC-GeoRAS and imported to HEC-RAS to create the geometry file. A hydrological statistical analysis was conducted to prepare the input design flows from data that corresponds to Porto Murtinho and Asunción fluvial stations. Finally, the finished model comprises a river reach of approximately 635 kilometers, more than 200 cross sections with 3,100 meters of spacing, and calibrated Manning's n value of 0.0245 for the main channel and a value of 0.04 for the floodplain. The simulation results, such as the water surface profiles, were processed by HEC-GeoRAS in ArcGIS to prepare floodplain maps for the entire reach.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-08-01The student, Roberto Takahashi, accepted the attached license on 2016-07-22 at 00:07.The student, Roberto Takahashi, submitted this Thesis for approval on 2016-07-22 at 00:10.This Thesis was approved for publication on 2016-07-22 at 15:30.DSpace SAF Submission Ingestion Package generated from Vireo submission #10068 on 2016-11-10 at 12:27:39Made available in DSpace on 2016-11-10T18:35:36Z (GMT).

9. Europe in the Encyclopédie
No full textIn the French Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers coordinated by Diderot and D’Alembert, known throughout Europe simply as the Encyclopédie, and one of the most influential works of the European Enlightenment, Louis de Jaucourt (1704–1779), author of hundreds of articles, provides a geographical description of Europe as one of the globe’s four continents–Australasia not yet at that point being known to the western world–and describes its rich cultural h..
Speech-based automatic closed caption alignment
No full textIn the Netherlands, four million people watch television programs with closed captions because they are hearing impaired or non-native speakers. Closed captions contain Dutch speech transcriptions and non-speech sound descriptions and are displayed as subtitles. Due to government obligation, the number of television programs that must be closed-captioned will increase to at least 95% in 2011. Closed caption alignment comprises the timing of the subtitles as closely as possible to the corresponding times of the video signal. Since alignment is a costly and labor intensive process demanding high quality outputs, an automated solution is desirable. This thesis addresses the application of automatic speech recognition to the task of on-line closed-captioning of television programs. The thesis focuses on the development of an automatic closed caption alignment system for TT888, a company that produces subtitles for Dutch-language television programs. Investigation of related research, consulting professional editors and analyses of a variety of captioned television programs have contributed to the development of an automatic closed-captioning system named SETH (Speech Estimating Title Heuristics). The core of the system is an algorithm capable of matching manually produced captions with speech transcriptions produced by a large vocabulary speech recognizer. The architecture of SETH combines the benefits of modular programming and the pipes and filters architecture. The best results are achieved when the speech is rather formal and nonspontaneous, pure Dutch pronounced by a native speaker and does not contain crosstalk nor background noise. Dissimilarities between the speech and captions are not a major problem as long as the captions include the most important words. The alignment algorithm is also robust to most of the insertions caused by music. Deviant language use, songs, spontaneous speech, strong regional accents are still a difficult job for the speech recognizer and hence a major problem in automatic closed caption alignment. Since there will always be broadcasts with poor speech quality, manual verification or adaptation of the subtitles remain necessary.Media & Knowledge EngineeringMan-Machine Interaction GroupElectrical Engineering, Mathematics and Computer Scienc
Discovery of an optical counterpart to the hyperluminous X-ray source in ESO 243-49
No full textThe existence of black holes of masses similar to 10(2)-10(5)M(circle dot) has important implications for the formation and evolution of star clusters and supermassive black holes. One of the strongest candidates to date is the hyperluminous X-ray source (HLX1), possibly located in the S0- a galaxy ESO 243-49, but the lack of an identifiable optical counterpart had hampered its interpretation. Using the Magellan telescope, we have discovered an unresolved optical source with R = 23.80 +/- 0.25 mag and V = 24.5 +/- 0.3 mag within HLX1's positional error circle. This implies an average X-ray/optical flux ratio similar to 500. Taking the same distance as ESO 243-49, we obtain an intrinsic brightness M-R = -11.0 +/- 0.3 mag, comparable to that of a massive globular cluster. Alternatively, the optical source is consistent with a main-sequence M star in the Galactic halo (for example an M4.4 star at approximate to 2.5 kpc). We also examined the properties of ESO 243-49 by combining Swift/Ultraviolet/Optical Telescope (UVOT) observations with stellar population modelling. We found that the overall emission is dominated by a similar to 5-Gyr-old stellar population, but the UV emission at approximate to 2000 angstrom is mostly due to ongoing star formation at a rate of similar to 0.03M(circle dot) yr(-1). The UV emission is more intense (at least a 9 sigma enhancement above the mean) north-east of the nucleus, in the same quadrant as HLX1. With the combined optical and X-ray measurements, we put constraints on the nature of HLX1. We rule out a foreground star and a background AGN. Two alternative scenarios are still viable. HLX1 could be an accreting intermediate mass black hole in a star cluster, which may itself be the stripped nucleus of a dwarf galaxy that passed through ESO 243-49, an event which might have caused the current episode of star formation. Or, it could be a neutron star in the Galactic halo, accreting from an M4-M5 donor star
