We describe the lithographic control over the spectral response of three-dimensional photonic crystals. By precise microfabrication of the geometry using a reproducible and reliable procedure consisting of electron beam lithography followed by dry etching, we have shifted the conduction band of crystals within the near-infrared. Such microfabrication has enabled us to reproducibly define photon...

This paper is about a new framework called DeduPlication (DduP). DduP aims to solve large scale deduplication problems on arbitrary data tuples. DduP tries to bridge the gap between big data, high performance and duplicate detection. At the moment a first prototype exists but the overall project status is work in progress. DduP utilises the promising successor of Apache Hadoop MapReduce [Had14]...

the application of ion current signals is one of the most recent approaches in engine management systems. by applying a small constant dc voltage across the electrodes of the spark plug and measuring the current through the electrode gap, the state of gas may be measured and investigated. in this paper a computer code is developed in order to analyze the state of gas during the combustion perio...

In this paper, we propose to optimize manufacturing methods of memory cells by produced silicon nanoparticles via electrical spark discharge of silicon electrodes in water to reduce the energy consumption for low power applications. The pulsed spark discharge with the peak current of 60 A and a duration of a single discharge pulse of 60 µs was used in our experiment. The structure, morphology, ...

Guglielmo Marconi probably made the first spread spectrum transmission without even realizing it. His primitive spark-gap transmitter used an RF bandwidth that was much wider than the information bandwidth. Little did he know that his experiment would spark a revolution in communications technology. Today, wireless communications plays an integral part in our daily lives. Cellular phones are qu...
