A new design method internal model control is proposed for multivariable over-actuated processes that are often encountered in complicated industrial processes. Due to the matrix that is adopted to describe over-actuated system is not square, many classical multivariable control methods can be hardly applied in such system. In this paper, based on method of virtual outputs, a new internal model...

in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

The present review paper has several objectives. Its primary aim is to give an idea of the general features virtual element methods (VEMs), which were introduced about a decade ago in field numerical for partial differential equations, order allow decompositions computational domain into polygons or polyhedra very shape. Nonetheless, also addressed readers who have already heard (and possibly r...

Background: According to the situation of education in Iran it is clear that over the years, there has been no successful attempt to identify related challenges and problems to development and implementation of virtual training. In this regard, the effect of this type of training influenced by the role of hidden curriculum of education in the country.   Based on this, current study has investig...

In many applications of Augmented Reality (AR), rectangular markers are tracked in real time by capturing with cameras. In this paper, we consider the AR application in which virtual objects are displayed onto markers while the markers and the cameras are freely moving. In this situation, the marker cannot be tracked when the marker is occluded by some objects. In this paper, we propose a metho...

Thas paper addresses the problem of computing the fundamental matrix which describes a geometric relationshzp between a pair of stereo images: the epipo1ar geometry. W e propose here a novel method based on virtual parallax. Instead of computing directely the 3 x 3 fundamental matrix, we compute a homography with one epipole position, and show that this is equivalent to compute the fundamental ...

introduction: virtual bronchoscopy is a reliable and efficient diagnostic method for primary symptoms of lung cancer. the segmentation of airways from ct images is a critical step for numerous virtual bronchoscopy applications. materials and methods: to overcome the limitations of the fuzzy connectedness method, the proposed technique, called fuzzy connectivity - fuzzy c-mean (fc-fcm), utilized...
