Are the inventor networks of Silicon Valley more densely connected than those of the Boston Route 128 corridor? The evidence remains mostly historical and controversial to date. We develop an analysis of all the patented inventors in both regions since 1975 and find that the networks of Silicon Valley are simultaneously more connected and less robust than those of Boston. Of greatest interest, ...

Electric agglomeration is the process in which particles are charged in electric fields and coagulate, which is enhanced by electric force or turbulence. The collection efficiency of submicron particles is improved, which can be a solution to submicron particle abatement in traditional electrostatic precipitators (ESPs), by using a pre-charger to increase median particle diameter and realizing ...

This paper presents an application of the element agglomeration-based coarsening procedure (agglomeration AMGe) proposed in [10], to build the components of a multigrid method for solving nonlinear finite element elliptic equations on general unstructured meshes. The agglomeration-based AMGe offers the ability to define coarse elements and element matrices, provided access to elements and eleme...

By combining persons around the world into a single market, the Internet may serve as a substitute for urban agglomeration. That is, the Internet may level the consumption playing field between large, variety-laden and small, variety-starved markets. However, if local content on the Internet is more prevalent in larger markets, then the Internet may be a complement for urban agglomeration. Char...

Spherical crystallization of drugs is the process of obtaining larger particles by agglomeration during crystallization. The most common techniques used to obtain such particles are spherical agglomeration and quasi-emulsion solvent diffusion. Ammonia diffusion systems and crystallo-co-agglomeration are extensions of these techniques. By controlling process parameters during crystallization, su...

Accompanied by the deep development of big data technologies in urbanization, the smart city, which is supported by big data technologies, has revealed its potential gradually. As the core content of smart city, the smart information service becomes a frequent subject and direction of related researches. This paper will firstly investigate the information service demand of various groups of peo...

In this paper, we aim at exploring how individual location decisions affect the shape of a growing city and, more precisely, how they may add up to a configuration that diverges from equilibrium configurations formulated ex-ante. To do so, we provide a two-sector city model merging a static equilibrium analysis with agent-based simulations. Results show that under strong agglomeration effects, ...
