Aftertreatment control and adaptation for automotive lean burn engines with HEGO sensors
(John Wiley & Sons, Ltd., 2004-03)
Control of aftertreatment systems for lean burn technology engines represents a big challenge, due to the lack of on-board emission measurements and the sensitivity of the hardware components to ageing and sulphur poisoning. ...
Static non-linear three-dimensional analysis of a riser bundle by a substructuring and incremental finite element algorithm
(John Wiley & Sons, Ltd, 1989-11)
The problem of static, non-linear, large three-dimensional deformation of riser bundles used in offshore oil and gas production is studied within the limits of small strain theory. The mathematical model consists of the ...
Hydrodynamic forces acting on cylinders oscillating at small amplitudes
(Elsevier, 1991-01)
The hydrodynamic forces resulting from small-amplitude harmonic oscillations of arbitrarily shaped cylinders are considered both experimentally and theoretically. The fluid is assumed to be initially at rest. The theoretical ...
The velocity potential and the interacting force for two spheres moving perpendicularly to the line joining their centers
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-05)
The velocity potential around two spheres moving perpendicularly to the line joining their centers is given by a series of spherical harmonics. The appropriateness of the truncation is evaluated by determining the residual ...
Highlight-line algorithm for realtime surface-quality assessment
(Elsevier, 1994-04)
A new method of surface-quality assessment is presented. The model of highlight lines is introduced, and its properties and applications in surface-quality evaluation are demonstrated. The differential equation of the ...
Initial water impact of a wedge at vertical and oblique angles
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-04)
This paper examines initial asymmetric wedge-impact flows with horizontal as well as vertical impact velocity. The method of two-dimensional vortex distributions is employed to model the initial-boundary-value problem. The ...
Toward extraplanetary under-ice exploration: Robotic steps in the Arctic
(Wiley Subscription Services, Inc., A Wiley Company, 2009-04)
This paper describes the design and use of two new autonomous underwater vehicles, Jaguar and Puma, which were deployed in the summer of 2007 at sites at 85°N latitude in the ice-covered Arctic Ocean to search for hydrothermal ...
Idle speed control of a direct injection spark ignition stratified charge engine
(John Wiley & Sons, Ltd., 2001-09)
Idle speed control is investigated for a direct injection, spark ignition, stratified charge (DISC) engine equipped with an electronic throttle. Such engines can be operated in multiple combustion modes. When operating in ...
A perspective on emerging automotive safety applications, derived from lessons learned through participation in the DARPA Grand Challenges
(Wiley Subscription Services, Inc., A Wiley Company, 2008-10)
This paper reports on various aspects of the Intelligent Vehicle Systems (IVS) team's involvement in the recent 2007 DARPA Urban Challenge, wherein our platform, the autonomous “XAV-250,'' competed as one of the 11 finalists ...
