The brain – computer interface (BCI) provides a communicational channel between human and machine. Most of these systems are based on brain activities. Brain Computer-Interfacing is a methodology that provides a way for communication with the outside environment using the brain thoughts. The success of this methodology depends on the selection of methods to process the brain signals in each pha...

The tremendous power and low price of today's computer systems have created the opportunity for exciting applications rich with graphics, audio and video. Despite this potential, planning computer systems to support the intensity of these multimedia applications is an extremely di cult task. We have developed a exible model and method that allows us to predict multimedia application performance...

The process of developing architectural forms has greatly been changed by advances in digital technology, especially in design tools and applications. In recent years, the advent of graphical scripting languages in the design process has profoundly affected 3D modeling. Scripting languages help develop algorithms and geometrical grammar of shapes based on their constituent parameters. This stud...

Abstract Commonplace computer applications on general-purpose computers increasingly are expected to meet “real-rate” requirements, processing or displaying data or images at an externally dr...

With the price of computer hardware decreasing steadily and the scope of data processing applications ever rising, the problem of upgrading a computer system is omnipresent. The myriad of potential pitfalls includes losing an investment in purchased hardware and software, reprogramming applications, reformatting data files, retraining personnel, operating two different systems in parallel durin...

operator's role in industrial control centers takes place in time, which is one of the most important determinants of whether an expected action is going to be successful or not. in certain situations, due to the complex nature of the work, the existing interfaces and already prepared procedures do not meet the dynamic requirements of operator's cognitive demands, making the control tasks unnec...

by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...
