Case studies of respiratory system models
No full textThis chapter draws together a series of case studies illustrating the application of a variety of modelling approaches relevant to the respiratory domain and also emphasises the range of applications in physiology, medical research, teaching and patient care. Emphasis is place on ensuring that the chosen modelling methodology is well-matched to the purpose of the investigation
Littoral drift computations on mutual wave and current influence
No full text11th Conference on Coastal Engineering in London 1968, the author presented a method for computing the littoral drift starting from the longshore current velocity as this is generated by the waves and with the assumption that the material is stirred up by the waves. In this paper measurements in a model basin are described by which the procedure is further tested. A comparison with littoral drift rates computed by this procedure and derived from accretion and erosion rates along the coast of Queensland (Australia) are presented. For a hypothetical coast the littoral transports with varying bed roughness are computed. The influence of this roughness on the assumptions forming the basis of the computation procedure is discussed.Hydraulic EngineeringCivil Engineering and Geoscience
Scour underneath submarine pipelines
No full textThis report deals with the physical experiments on scour underneath submarine pipelines, carried out as part of the MaTS project on the stability of submarine pipelines. Moreover, these experiments, which have been carried out in the laboratory for fluid mechanics of the Department of Civil Engineering of the Delft University of Technology, are the topic of the student thesis of the author, who has been joining the Group of Coastal Engineering as a student assistant. His work has been accompanied by ir. W. Leeuwestein. Prof.dr.ir.E.W.Bijker was the supervisor of the entire project on the stability of pipelines. After the introduction in chapter 2, in chapter 3 a summing up is given of the previous research on the subject and the theory needed to approach the problem of the scour process underneath pipelines. In the following chapter a description is given of the way in which the experiments have been carried out. Chapter 5 gives the results of the experiments and using the results a functional relation has been tried to find between the scour depth on the one hand and the flow, pipe and sand parameters on the other hand. In chapter 6 the use of physical experiments to predict prototype scour depths is discussed by studying the concerning scale relations. This thesis ends with some conclusions.Civil Engineering and Geoscience
Advertisement using Kit Carson to advertise Southern Pacific's Four Great Routes, [s.d.]
No full textPhotograph of an advertisement using Kit Carson to advertise Southern Pacific's Four Great Routes, [s.d.]. A drawing of a fur--clad trapper depicted near a saddled horse at Lake Tahoe can be seen at top, while an etching of two women sitting at a boudoir is visible at center. Four maps of travel routes across the United States can be seen side-by-side across the bottom. Photonegative sleeve reads, "S.P. Lord Thomas J. Logan. Printed".; Advertisement reads [part 1 of 2]: "Kit Carson knew the 'four great routes'. This pioneer chose frequently to 'go one way, return another, see the whole Pacific Coast.' Kit Carson! Back and forth over a stage 1500 miles square, routing Indians, leading Fremont through the mountains, crawling barefoot over cactus needles to save Kearney's army in the conquest of California, spiking Spanish cannon at San Francisco, and dashing away again over Arizona and New Mexico to honeymoon with Josefa Jaramillo, his dark-eyed bride -- here was a man who knew the West and all its trails! Kit Carson passed from the scene just as the first overland railroad (Central Pacific, forerunner of Southern Pacific) built eastward from the western ocean in 1867. The rails of Southern Pacific's Overland Route today follow close to the path made by Kit Carson to California. Sunset, Golden State and Shasta Routes also follow many a league of Kit Carson's gallopings. At Klamath Lake, in Oregon, Carson and Fremont fought a famous Indian battle near where the Siskiyou and Cascade lines of Shasta Route divide to embrace Crater Lake. Southern Pacific's four routes to California are pioneer western lines and inheritors of the best natural routes as found by early-day frontiersmen. These four routes give you a splendid chance to see the epic West and the whole Pacific Coast. Only Southern Pacific offers four routes. You can go one way, return another. Stop over anywhere. Be sure to send your name and address to E.W. Clapp, traffic manager, 310 South Michigan Boulevard, Chicago, for free travel book with illustrations, entitled 'How Best to See the Pacific Coast'."; Advertisement reads [part 2 of 2]: "Southern Pacific. Four Great Routes. -- Sunset Route: New York to New Orleans by Southern Pacific steamer (berth, meals included on steamer), or by rail. Thence Houston, San Antonio and El Paso to San Diego via Carriso Gorge, Los Angeles and San Francisco, without changes. Apache Trail motor highway in Arizona, delightful one-day side-trip. 'Sunset Limited.' -- Overland (Lake Tahoe Line) Route: Straight across midcontinent from Chicago, St. Louis, Kansas City and Denver. Across Great Salt Lake by rail, through Nevada's mountain-rimmed basin, down American River Canyon and across central California. Rock-ballasted roadbed, oil-burning locomotives and excellent cuisine, as on all four routes. 'San Francisco Overland Limited.' -- Golden State Route: The direct line, Chicago to Los Angeles, San Diego and Santa Barbara, via Kansas City. Joins Sunset Route at El Paso. Stop over there to see Juarez, Old Mexico. Apache Trail highway side-trip in Arizona. Through sleepers from Minneapolis, Chicago, St. Louis, Kansas City and Memphis. 'Golden State Limited' -- none faster nor finer. -- Shasta Route: For travelers to California via Portland, Oregon. Choice of two lines through Oregon: Siskiyou Line, through river valleys, or new scenic Cascade Line through alpine forests and lakes. These embrace Crater Lake and rejoin near Mount Shasta: thence to San Francisco. Optional motor coach detour through California's Redwood Empire. 'The Cascade.' -- Lake Tahoe. 6200 feet high, near the Sierra Nevada summit, is accessible by Overland Route.

Golfbreker te Sines
No full textIn het kader van het afstuderen wordt een studie verricht die zal leiden tot een nieuw ontwerp van de bezweken golfbreker te Sines, Portugal. De uitgangspunten voor dit ontwerp zijn: - het alignement van de te ontwerpen golfbreker zal samenvallen met dat van de bestaande. - er wordt een ontwerp gemaakt onafhankelijk van de bestaande situatie, waarbij er van wordt uitgegaan, dat op de bestaande plaats nog niets is gebouwd. Het vooronderzoek is het eerste deel van deze studie. Allereerst zal worden ingegaan op het bestaande ontwerp, de uitgangspunten die daaraan ten grondslag hebben gelegen, de omstandigheden van bezwijken en de aard van de opgetreden schade. Het tweede deel is het hoofdontwerp van de golfbreker te Sines. Het derde deel bestaat uit de golfhoogten bij de golfbreker Cap Sines.KustwaterbouwkundeHydraulic EngineeringCivil Engineering and Geoscience
