We have entered an era of chip multiprocessor (CMP) platforms, where performance is delivered with the integration of more and more cores on a die. Tera-scale CMP architectures, consisting of several tens of physical cores and hundreds of hardware threads, are highly suitable for throughput computing especially in the server market place. In this paper, we start by highlighting tera-scale poten...

The evolution and collapse of a gaseous toroidal vortex under the action of self-gravitation are considered using the Hamiltonian mechanics approach. It is shown that evolution occurs in three main stages separated by characteristic time scales. First, a compression along the small radius to a quasi-equilibrium state takes place, followed by a slower compression along the large radius to a more...

Surface diffusion is important for a broad range of chemical and physical processes that take place at the surfaces amorphous solids, including surface crystallization. In this work, temporal evolution nanoholes monitored with atomic force microscopy to quantify dynamics selenium. molecular glasses, coefficient has been shown scale crystal growth rate (us) according power relation us ≈ Ds0.87. ...

Specific pollen placement by zygomorphic flowers on pollinators is one of the key innovations of angiosperm evolution [1]. In most phylogenetic lineages that have evolved zygomorphic flowers, reproductive organs are positioned either in the lower or upper part of the flower. Although these specific positions largely enhance pollen economy, they also represent architectural constraints such that...

The term mixing is confusing because it is used to describe transport mechanisms for both flash mixing (reagent dispersion and homogenisation with water mixing) and agitation (flocculation mixing) because each of these mechanisms requires different flow characteristics in order to take place with maximum efficiency. Flash mixing should take place under conditions of mixing on macro-scale with m...

one of the most traditional architecture and urban planning patterns is bazaar. the aim of this paper is studying social, economical and architectural features of traditional bazaars. the claim of this study is that they are significant relationship between social and economical values of bazaars with their architectural values. bazaar usually is located along the main routes of the city and ex...

Software evolution is expensive. Lehman identifies several problems associated with it: Continuous adaptation, increasing complexity, continuing growth, and declining quality. This paper proposes that a reflective software engineering environment will address these problems by employing languages and techniques from the software architecture community. Creating a software system will involve ma...
