Abstract: The present work is a study of a thin shallow shell having a specific type of deviation from axial symmetry, i.e., the portion of an elliptic paraboloid near its vertex. The singular solutions ...

Abstract: Timber trusses in an industrial warehouse sustained damage due to excessive snow loads. The owner asked the writer's firm to evaluate the severity of the damage, determine the safe load-carrying capacity of the trusses, ...

Abstract: Concentrated solar plants have been designed to store thermal energy so as to produce power after sundown, but heat storage should also be of interest to operators of nuclear power plants. Adding heat storage to light-water ...

Abstract: Instead of waiting to fight diseases inside the human body, engineering can establish lines of defense further out by either intercepting and neutralizing the pathogens before they reach humans or diluting them so much ...

Abstract: This paper presents the currently envisioned role of the Space Station relative to servicing both at and distant from the Station. Once operational (1990+), the Station will substantially benefit ...

Abstract: The fluoridesaltcooled hightemperature reactor (FHR) is a new reactor concept, which combines lowpressure liquid salt coolant and hightemperature tristructural isotropic (TRISO) particle fuel. The refractory TRISO particle ...

Abstract: Stress-laminated timber bridge decks consist of several sawn timber beams or glue-laminated (glulam) beams held together with prestressed steel bars. Frictional shear stresses between the beams transfer loads between ...

Abstract: A new design paradigm for nuclear power plants is needed to complement the increasing adoption of low marginal cost variable renewable energy resources. The situation is reflected in the wholesale electricity price–duration ...

Abstract: We describe a roadmap using three sets of technologies to enable base-load nuclear reactors to replace all fossil fuels in a low-carbon world. The technologies integrate nuclear, wind, solar, hydroelectricity and biomass ...

Abstract: Liquid-fluoride-salt heat transfer fluids are proposed to raise the heat-to-electricity efficiencies of solar power towers to about 50%. The liquid salt would deliver heat from the solar furnace ...
