This paper analyses the effect of locally bounded knowledge spillovers on regional differences in growth. A model will be developed that allows spillovers to take place across regions. Certain conditions determine the amount of spillovers a region receives. By use of simulations (with randomised parameter constellations), it is possible to examine the general behaviour of the model. It is found...

In the gap Hamming distance problem, two parties must determine whether their respective strings x; y 2 f0; 1g are at Hamming distance less than n=2 p n or greater than n=2 C p n: In a recent tour de force, Chakrabarti and Regev (STOC ’11) proved the long-conjectured ̋.n/ bound on the randomized communication complexity of this problem. In follow-up work several months ago, Vidick (2010; ECCC T...

Using an external electric field, one can modulate the band gap of Bernal stacked bilayer graphene by breaking the A-[Formula: see text] symmetry. We analyze strain effects on the bilayer graphene using the extended Hückel theory and find that reduced interlayer distance results in higher band gap modulation, as expected. Furthermore, above about 2.5 Å interlayer distance, the band gap is direc...

The behavior of nanoparticles under nanofluidic confinement depends strongly on their distance to the confining walls; however, a measurement in which the gap distance is varied is challenging. Here, we present a versatile setup for investigating the behavior of nanoparticles as a function of the gap distance, which is controlled to the nanometer. The setup is designed as an open system that op...

in magnetic abrasive finishing (maf), abrasive grains as a tool move on surface and can removechip from surface of work piece. in this study al 6061 tube was considered as the work piece andthe effect of finishing parameters such as gap distance between tube and poles, rotational speed oftube, abrasive ration and finishing time on surface roughness was investigated. the mixture offerromagnetic ...

Design and construction of a capacitor sensor with a precise readout system are described in this paper. A variable air-gap capacitive transducer was constructed and for signalmeasurement a successful attempt was made to exploit the capacitance changes in terms of the phase angle of the detected signal. The reported setup makes it possible to detect capacitance changes of the order of 2.5 fF in...
