the effects of single walled carbon nanotube (swcnt) on mixed convection in a cavity are investigated numerically. the problem is studied for different richardson numbers (0.1-10), volume fractions of nanotubes (0-1%), and aspect ratio of the cavity (0.5-2.5) when the grashof number is equal to 103. the volume fraction of added nanotubes to water as base fluid are lowers than 1% to make dilute ...

This study examines the capability of the Relevance Vector Machine (RVM) and Multivariate Adaptive Regression Spline (MARS) for prediction of ultimate capacity of driven piles and drilled shafts. RVM is a sparse method for training generalized linear models, while MARS technique is basically an adaptive piece-wise regression approach. In this paper, pile capacity prediction models are developed...

this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...

This work considers the evolutionary perspective of method engineering. It presents an approach for method engineering based on the evolution of an existing method, model or meta-model into a new one satisfying a different engineering objective. This approach proposes several different strategies to evolve from the initial paradigm to a new one and provides guidelines supporting these strategie...

Earthquake is one of the most commonly happened disasters with devastating consequences and poses significant risks to human society. The ability to determine the time and location of an earthquake can provide valuable information for rescue guidance, hazard assessment and scientific study. After a destructive earthquake, an accurate earthquake location is the most importtance information neede...

The scientific method serves as a good metaphor for several practices in Extreme Programming (XP). We explore the commonalities and differences and show that the scientific method, by analogy, can be used to better understand Test Driven Development (and vice versa).

Novel and intelligent visualization methods are being developed in order to accommodate user searching and browsing tasks, including new and advanced functionalities. Besides, research in the field of user modeling is progressing in order to personalize these visualization systems, according to its users’ individual profiles. However, employing a single visualization system, may not suit best a...

Handling the increasing number of biological repositories and the growing amount of information they contain is a significant challenge for researchers. Thus, Semantic Web Technologies are the basis of the new approaches that are dealing with such challenges. In this paper, we describe a methodology to manage the integration of biomedical repositories into a knowledge base. This method is based...

Software Architecture allows for early assessment of and design for quality attributes of a software system. It provides an important help for current software development. The development of software architecture is complex due to the absence of a standard way that lead the generation of software architecture artifacts. In this paper we define an architecture design method that provides the sy...
