P ERSONAL transportation offers people freedom, but this choice of freedom creates a conflict with growing environmental concerns and the sustainability of humanity's use of natural resources. Hybrid electric vehicles (HEVs) improve fuel efficiency by optimizing powertrain operation and recovering kinetic energy during braking, hence reducing liquid fuel consumption in the transportation sector...

Cone-beam imaging with C-arm systems has become a valuable tool in interventional radiology. Currently, a simple circular trajectory is used, but future applications should use more sophisticated source trajectories, not only to avoid cone-beam artifacts but also to allow extended volume imaging. One attractive strategy to achieve these two goals is to use a source trajectory that consists of t...

The authors report a series of 43 patients suffering from lower limb pain, almost constantly associated with chronic or acute backpain, treated by microsurgical nerve root decompression and by implantation of a soft intervertebral prothesis (DIAM). Satisfying results were obtained in 97% of cases, inducing the authors to consider the device a reliable tool for curing low-back pain and sciatica....

Photographic images annotation is a complex problem. Indeed, the visual characteristics of objects of a class vary with the considered instance and the shooting conditions. In this paper we proposed a visual characterization of object parts, called "Visual Phrase", robust to these variations. A Visual Phrase is a set of regions of interest built according to pre-difined criteria; a topological ...

The Kadomtsev-Petviashvili II (KPII) equation admits a large variety of multi-soliton solutions which exhibit both elastic as well as inelastic types of interactions. This work investigates a general class of multi-solitons which were not previously studied, and which do not in general conserve the number of line solitons after interaction. The incoming and outgoing line solitons for these solu...

Diffusion tensor microimaging with 40 μm isotropic voxels at 16.4 T was used to investigate compartmentation of water diffusion and biexponential diffusion decay in formalin fixed prostate tissue. Tissue samples (~28 mm) were similar in volume to a typical prostate DWI voxel in vivo and were imaged with ~400,000 voxels. The bulk mean diffusivity (‘ADC’) of epithelial, stromal, and ductal/acinal...

The objective of this paper is to develop different method for image compression without reducing the resolution for Region of Interest in the images. Mostly medical images for diagnosis purpose have some specific region; this region is known as Region of Interest (ROI). Here we separate our ROI from background and then apply Feed Forward Neural Network (FFN) compression to ROI and background i...
