Monitoring stream of social media posts has attracted significant attention in the last view years. Real time summarization in microblog aims at providing new relevant and non redundant information about an event as soon as it occurs. In this paper, we propose a novel continuous summarization approach in which information updates are pushed in real time. The decision to select/ignore incoming i...

During the past twenty years, flow chemistry has emerged as an enabling tool to simplify, accelerate, integrate, scale-up and automatize chemical reactions [...]

§ The interactive aerodynamics of new V/STOL designs require a new approach to ground testing, where multiple properties are measured both on and away from surfaces during continuous changes in test parameters. Using a set of experiments of increasing complexity, a new capability is demonstrated for capturing surface pressure, velocity fields and vortex flow features over a range of test parame...

Many methods have been developed for structural size and configuration optimization in which cross-sectional areas are usually assumed to be continuous. In most practical structural engineering design problems, however, the design variables are discrete. This paper proposes two efficient structural optimization methods based on the harmony search (HS) heuristic algorithm that treat both discret...

Polymeric flat-sheet membranes and hollow fibers were prepared via UV photo-initiated polymerization of acrylic acid at the surface commercial polyether sulfones (PES) membranes. These polymeric materials permitted to immobilize efficiently palladium nanoparticles (PdNP), which exhibited a mean diameter in range 4?6 nm. synthesized by chemical reduction Pd(II) precursors presence corresponding ...

This thesis contributes to the understanding of computational capabilities of multi-robot systems by viewing them as devices in which mechanical and electronic components jointly perform computation. We show that a multi-robot system can use physical embodiment and spatial embeddedness as computational resources for two types of problems: (i) a continuous optimization problem of achieving optim...

A CGS is of the most important parts in natural gas transmission pipelines in which the high inlet natural gas (NG) pressure is reduced to much lower value by employing a throttling valve. This pressure drop causes hydrate forming, preventing stable NG flow through the pipeline. To prevent hydrate forming, NG is usually preheated by heaters which burns remarkable amount of NG. In this work, a n...

Here we describe a novel approach to generate monodisperse silicone microdroplets via microfluidic based microemulsion. Through a flow-focusing configuration, a continuous flow of commercially available silicone precursor solution has been successfully dispersed into discrete microdroplets with narrow size distribution, which are future solidified into stable microparticles by subsequent therma...
