Graph algorithms such as breadth-first search (BFS) have been gaining ever-increasing importance in the era of Big Data. However, the memory bandwidth remains the key performance bottleneck for graph processing. To address this problem, we utilize processing-in-memory (PIM), combined with non-volatile metal-oxide resistive random access memory (ReRAM), to improve the performance of both computation...
We propose a method to generate cylindrical vector beams (CVBs) using a specially designed multicore photonic crystal fiber (PCF). In a PCF with six cores arranged symmetrically around the fiber axis, the light fields in the cores present different polarization states, promising the compositions of vector modes. By introducing small defect airholes in the cladding region and enlarging airholes around...
Increasing time-series remote sensing images provide the information about the evolution processes of ecosystems on multi-spatial scales. Vegetation plays an important role in sustaining the natural environment and supporting human being with goods and ecosystem services. Detection of vegetation degradation has become a hot spot of multi-disciplinary researches recently. In this paper, a case study...
In thermosonic wire bonding process, the bonding power setting and bonding temperature are important factors to the vibration of transducer system, which plays a crucial role in bonding formation. In a number of bonding experiments which were carried out at different power setting and temperature, vibration velocity at the tip of transducer was monitored. Vibration Signals were analyzed by wavelet...
