The effect of hydrate content on seismic attenuation: A case study for Mallik 2L-38 well data, Mackenzie delta, Canada
No full textObservations of velocities in sediments containing gashydrates show that the strength of sediments increases with hydrate saturation. Hence it is expected that the attenuation of these sediments will decrease with increasing hydrate saturation. However, sonic log measurements in the Mallik 2L-38 well and cross hole tomography measurements in the Mallik field have shown that attenuation increases with hydrate saturation. We studied a range of mechanisms by which increasing hydrate saturation could cause increased attenuation. We found that a difference in permeability between the host sediment and the newly formed hydrate can produce the observed effect. We modelled attenuation in terms of Biot and squirt flow mechanisms in composite media. We have used our model to predict observed attenuations in the Mallik 2L-38 well, Mackenzie Delta, Canada

2L-2L Converter:Switched Inductor Based High Voltage Step-up Converter for Fuel Cell Vehicular Applications
No full textIn this article, a novel 2L-2L power converter is articulated for vehicular application. Due to low output voltage generated from fuel cells; series/parallel arrangement is not a key to attain high voltage/current. As a result, to attain high voltage at the output, high gain DC to DC power converters play a cardinal job. A novel 2L-2L converter is proposed by replacing inductors of L-L converter by switched inductors to enhance the voltage conversion capability. The CCM and DCM operations of the 2L-2L converter with its mathematical analysis are described in detail. Moreover, the proposed 2L-2L converter is compared with similar converters to spotlight the key features. The result obtained through simulation work is presented which validate the performance and mathematical analysis of 2L-2L converter.<br/

2L-CONVEX POLYOMINOES: GEOMETRICAL ASPECTS
No full textInternational audienceA polyomino P is called 2L-convex if for every two cells there exists a monotone path included in P with at most two changes of direction. This paper studies the geometrical aspects of a sub-class of 2L-convex polyominoes called I0,0 and states a characterization of 2L it in terms of monotone paths. In a second part, four geometries are introduced and the tomographical point of view is investigated using the switching components (that is, the elements of this sub-class that have the same projections). Finally, some unicity results are given for the reconstruction of these polyominoes according to their projections
