The ethnic composition of US inventors is undergoing a signi…cant transformation — with deep impacts for the overall agglomeration of US innovation. This study applies an ethnic-name database to individual US patent records to explore these trends with greater detail. The contributions of Chinese and Indian scientists and engineers to US technology formation increase dramatically in the 1990s. ...

In the production of high speed steel, the rolling a ects the micro-structure of the steel, which in turn in uences the mechanical properties. Speci cally, the distribution of carbide is essential, since cracks propagate within the carbide agglomerations. In current quality control, the properties of the steel are assessed manually by comparison with a standard chart, containing representative ...

This paper presents an integrated view of economic growth, development traps, and economic geography. We explain why there is income convergence among some countries (neoclassical regime) and income divergence among others (poverty trap regime). Income convergence (divergence) and manufacturing industry di¤usion (agglomeration) are re-enforcing each other in a cumulative process. Moreover, trad...

in recent years, the studies of location play a key role in success and stability of economic activities. location studies are under consideration in both national and international levels. meanwhile, identification of goals and methods of solving location problems have significant importance. the purpose of this paper is to examine spatial distribution of economic activities in 14 zones of esf...

This paper examines the agglomeration benefits of a transportation improvement in a city by modeling the microstructure of urban agglomeration based on monopolistic competition of differentiated intermediate products. Properly extended to include variety distortion in addition to price distortion, Harberger’s measure of excess burden yields the agglomeration benefits. The agglomeration benefits...

This paper provides a survey on K-NN queries, DCR query, agglomerative complete linkage clustering and Extension of edit-distance-based definition graph algorithm and solving decision problems under uncertainty. This existing system give an beginning to Graph agglomeration aims to divide information into clusters per their similarities, and variety of algorithms are planned for agglomeration gr...

The paper econometrically investigates the determinants of industrial agglomeration in 2001, taking as reference recently developed measures. The considered explanatory variables comprised sector-level variables and local infrastructure and incentive policies variables. The evidence showed that variables reflecting input utilization and knowledge spillovers at sector-level had important impacts...
