Homogenization has proved its effectiveness as a method of upscaling for linear problems, as they occur in single-phase porous media flow for arbitrary heterogeneous rocks. Here we extend the classical homogenization approach to nonlinear problems by considering incompressible, immiscible two-phase porous media flow. The extensions have been based on the principle of preservation of form, stati...

Numerous organizations collect and share large amounts of data due to the proliferation of information technologies and internet. The information extracted from these databases through data mining process may reveal private information of individuals. Privacy preserving data mining is a new research area, which allows sharing of privacy-sensitive data for analysis purpose. In this paper a hybri...

Damping of coherent oscillations by feedback is straightforward in principle. It has been a vital ingredient for the safe operation of accelerators since a long time [1,2]. The increasing dimensions and beam intensities of the new generation of hadron colliders impose unprecedented demands on the performance of future systems. The arguments leading to the specification of a transverse feedback ...

We present a case of patient with an incidental finding isolated radial head osteochondroma. This progressively enlarged to become symptomatic causing gradual subluxation the radio-capitellar joint. Marginal excision and annular ligament reconstruction was performed using forearm fascia graft. The made full recovery symptom resolution preservation range movement. He successfully returned physic...

Interactive fiction and video games are part of our cultural heritage. As original systems cease to work because of hardware and media failures, methods to preserve obsolete video games for future generations have to be developed. The public interest in early video games is high, as exhibitions, regular magazines on the topic and newspaper articles demonstrate. Moreover, games considered to be ...

Purpose of the study: This study analyzes the incidence on hip dislocation of a posterior minimally invasive approach that combines the suture of the capsular joint and the preservation of the piriformis muscle. Material and methods: A first prospective series of 98 patients having undergone hip prosthesis by a posterior minimally invasive approach that combines piriformis preservation and caps...

From vehicle, gun, projectile and charge system, a basic principle has been presented for the first time in the paper by making use of the random-simulation technology based on the theory of interior ballistic, automat, vibration of self-propelled gun system, initial disturbing and external ballistic etc. The basic principle is achieved by simulating a movement procedure of the gun-vehicle syst...

The square-root principle is known to achieve low search time for peer-to-peer search techniques that do not utilize query routing indices (e.g., query flooding or random walk searches). Under this principle, each object is probed with probability proportional to the square root of its query popularity. Existing search methods realize the square-root principle by using either object replication...

Abnormal sensory processing has been implicated in the pathophysiology of primary dystonia. In the globus pallidus internus (GPi), the primary output structure of the basal ganglia, many neurons respond to sensory (proprioceptive) stimulation. Here we have characterized GPi neuronal responses to passive movement of the contralateral limbs in 22 patients with primary dystonia undergoing microele...
