Wraps. Condizione: Very good. Presumed First Edition, First printing. Various paginations (approximately 130 pages). Figures. Tables. References. Format is 8.5 inches by 11 inches. The use of multiple predictor smoothing methods in sampling-based sensitivity analyses of complex models is investigated. Sensitivity analysis procedures based on smoothing methods employing the stepwise application of the following nonparametric regression techniques are described: (1) locally weighted regression, (2) additive models, (3) projection pursuit regression, and (4) recursive partitioning regression. The indicated procedures are illustrated with both simple test problems and results from a performance assessment for a radioactive waste disposal facility. Smoothing procedures based on nonparametric regression techniques can yield more informative results than can be obtained with more traditional sensitivity analysis procedures based on linear regression, rank regression or quadratic regression when nonlinear relationships between model inputs and predictions are present.…

Wraps. Presumed first edition/first printing. Includes illustrations. Various paginations, approximately 200 pages. References. Figures. Tables. Relationships to determine the probability that a weak link (WL) strong link (SL) safety system will fail to function as intended in a fire environment are investigated. From Wikipedia: "A strong link/weak link and exclusion zone nuclear detonation mechanism is a type of safety mechanism employed in the arming and firing mechanisms of modern nuclear weapons. The safety mechanism starts by enclosing the electronics and mechanical components used to arm and fire the nuclear weapon with a mechanical and electrical isolation barrier, forming the exclusion zone. This is insulated from mechanical, thermal, and electrical disruptions (such as static electricity, lightning, fire). Between the exclusion zone and the actual detonators, a normally disconnected link mechanism is used, such as a switch which has a built in motor to activate it. The arming system has to activate the switch in order to connect the firing circuits to the detonators in the weapon. This disconnection, which requires the arming mechanism to operate, is called the strong link. As a safety mechanism, a weak link is also built into the system. This is a set of components designed to fail at lower stresses (thermal, mechanical, and electrical) than will cause failure of the strong link mechanisms. These mechanisms do not prevent misuse of the weapon, or an accident from physically causing initiation of the explosives or detonators directly from extremely high temperatures, impact forces, or electrical disturbance such as lightning."
