Recent data on polarized proton knockout reactions off He nuclei suggest a small but nonzero modification of proton electromagnetic form factors in medium. Using model independent relations derived on the basis of quarkhadron duality, we relate the medium modification of the form factors to the modification at large x of the deep-inelastic structure function of a bound proton. This places stron...

Gauge invariant density-density correlators yield detailed information on hadron structure. Hadron deformation and form factors can be extracted for momentum transfers up to about 6 GeV 2. We use stochastic techniques and dilution to compute the all to all propagator required for the exact evaluation of density-density correlators. We present first results for the pion form factor.

In this paper we present a new search method for partitioning and scheduling a set of periodic tasks on a multiprocessor or distributed architecture. The schedule is fixedpriority driven and task migration is not allowed. The aim of this algorithm is to minimize the number of processors used for scheduling a set of tasks. Moreover, we assume that the number of processors obtained by our method ...

A new free-form deformation method is presented in this paper. The deformation of an object is achieved by attaching it to two parametric surfaces, namely the shape surface S u v ( , ) and the height surface H u v ( , ) . A control point or vertex of object is projected onto the shape surface along its normal and a correspondence between the point and its projection on the shape surface is esta...

The Minimum Bin Slack is a heuristic proposed by Gupta and Ho [6]. Such algorithm is defined by its authors as an algorithm focused on the container. MBS starts from the idea that minimizing the number of containers is equivalent to reduce the left space in the containers: thus, less quantity of containers means less left space in the containers. Considering this idea, MBS algorithm uses the co...

We introduce a novel finite-difference (FD) approach for seismic wave extrapolation in time. We derive the coefficients of the finite-difference operator from a lowrank approximation of the space-wavenumber, wave-propagator matrix. Applying the technique of lowrank finite-differences, we also improve the finite difference scheme of the two-way Fourier finite differences (FFD). We call the new o...

We introduce a novel technique for seismic wave extrapolation in time. The technique involves cascading a Fourier Transform operator and a finite difference operator to form a chain operator: Fourier Finite Differences (FFD). We derive the FFD operator from a pseudo-analytical solution of the acoustic wave equation. 2-D synthetic examples demonstrate that the FFD operator can have high accuracy...

In this paper we present a new approach for free-formdeformation of volume object. Free-form-deformation (FFD) is used as method for calculating the deformation. Rendering is based on the inverse deformation of viewing rays using approaches adapted from Barr [1] and Kurzion [10]. Thus this new approach doesn’t suffer from the overhead of the intermediate step to reconstruct the deformed volume ...
