Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...

barrel vaults are attractive space structures that cover large area without intermediate supports. in this paper, the charged search system (css) optimization algorithm is employed for optimal design of barrel vaults. this method utilizes the governing laws of coulomb and gauss from electrostatics and the newtonian law of mechanics. the results demonstrate the efficiency of the discrete css alg...

The present paper aims to investigate the effects of modularity and the layout of subsystems and parts of a complex system on its maintainability. For this purpose, four objective functions have been considered simultaneously: I) maximizing the level of accordance between system design and optimum modularity design,II) maximizing the level of accessibility and the maintenance space required,III...

Since nature of architecture is quite different from that of other fields of study, the criteria used forjudging projects in this field continuously undergo some changes. On the other hand, because of the undeniable role ofhuman factors in judging the projects, there is always a percentage of deviation from the standard given the interestsof the judging committee. The standards of judging archi...

The size of search spaces in embedded system design is one of the most critical problems during design space exploration. Pareto-Front Arithmetics (PFA) has shown to be useful to overcome this problem by decomposing a hierarchical search space and just exploring each part of the system separately. Later, the exploration results are combined at higher levels of the hierarchy. In order to decreas...

We shouldn't expect technologies that impact peoples′ daily lives to be adopted before they are demonstrated as reliable, useful and simple to deploy. Measured against this criterion ubiquitous computing is still in its infancy. We present an overview of the spectrum of research in ubiquitous systems currently in progress at the LCE which aims to address some of these issues. Ubiquitous computi...

The methodology of AI as the general study of natural and artiicial intelligence is outlined, including exploration of designs for a variety of behaving systems, for both scientiic and engineering purposes. Thèdesign-stance' treats minds as sophisticated self-monitoring, self-modifying control systems. Diierent architectures can satisfy that description. Exploration of possible requirements and...
