  • The use of an exhaust-driven boosting device can significantly improve the performance of a vehicle using a small displacement engine. One of the concerns relative to the performance of vehicles using these devices is ''turbo lag,'' or the period of time during which no boost is generated. This paper presents the results of designed experiments comparing the performance of a fixed geometry, wastegated turbocharger to a variable geometry turbocharger incorporating a low-loss bearing system. In addition, experimental tests are presented for the naturally aspirated engine in the same vehicle. The results of the experiments show improvements with the use ofmore » pressure boosting and that there are signifcant differences in the boosting devices tested; specifically, the use of a variable geometry turbocharger demonstrates significant reduction in the length of time required to reach boost and reduced acceleration times for the tests conducted.« less
  • Structural styles in the southern Alps reflect the mechanisms that extended the crust to form a Jurassic passive margin. The southern Alps consist of an array of half-grabens, each with a west-tilted floor bounded on the west by an east-dipping master fault. Antithetic faults divide each half-graben into a western depocenter and an eastern ramping marginal plateau, shallower and less subsident. The half-grabens, from west to east, are M. Nudo-Arbostora, M. Generoso-Albenza, West Sebino-Botticino, East Sebino-Trento, and Belluno-Friuli. Typical antithetic faults, commonly with further Cenozoic displacements, include the Ballino and Carnian Prealps fault systems. Timing of half-graven formation shows anmore » eastward-younging age progression, suggesting that extension propagated by steps into unextended crust over much of early and middle Liassic time. The continent-facing dip of faults in the southern Alps is the reverse of the dip predicted by simple symmetrical extension models with only ductile extension in the lower lithosphere. However, it agrees with models in which low-angle shearing cuts through the entire lithosphere and results in structural asymmetry of conjugate margins. The authors suggest that the polarity of the observed shallow structures is the consequence of a gently east-dipping master shear cutting through the lithosphere at depth beneath the Brianconnais-southern Alps systems.« less
  • Building geometry is essential to any simulation of building performance. This paper examines the importing of building geometry into simulation of energy performance from the users' point of view. It lists performance requirements for graphic user interfaces that input building geometry, and discusses the basic options in moving from two- to three-dimensional definition of geometry and the ways to import that geometry into energy simulation. The obvious answer lies in software interoperability. With the BLIS group of interoperable software one can interactively import building geometry from CAD into EnergyPlus and dramatically reduce the effort otherwise needed for manual input.The resultingmore » savings may greatly increase the value obtained from simulation, the number of projects in which energy performance simulation is used, and expedite decision making in the design process.« less
  • A sophisticated, commercially available, pseudo three-dimensional fracture simulator is used to demonstrate that during hydraulic fracturing a single net-treating pressure plot and fracture-fluid leak-off curve can be achieved by radically different fracture geometries and a large range of reservoir properties. The simulated fracture geometry for each reservoir description and combination are used to predict estimated future production performance using reservoir simulation. Production performance is shown to be a combination of reservoir quality and fracture geometry. However, essentially identical long-term production performance can be expected from different combinations of reservoir quality and fracture geometry. Consequently, decisions made from fracture simulations usingmore » only real-time fracture treatment data may yield unreliable correlations between hydraulic fracture design and reservoir performance.« less
