This paper describes the current state of RUgle, a system for classifying and indexing papers made available on the World Wide Web, in a domain-independent and universal manner. By building RUgle with the most relaxed restrictions possible on the formatting of the documents it can process, we hope to create a system that can combine the best features of(More)
Multilevel voltage source inverter has been recognized as an important alternative to the normal two level voltage source inverter, especially in high power application. Using multilevel technique, the output voltage amplitude is increased, switching devices stress is reduced and the overall harmonics profile is improved. Three presentable topologies can b(More)
BEOL-friendly Access Devices (AD) based on Cu-containing MIEC materials[1-4] are integrated in large (512×1024) arrays at 100% yield, and are successfully co-integrated together with Phase Change Memory (PCM). Numerous desirable attributes are demonstrated: the large currents (>200µA) needed for PCM, the bipolar operation required for high-performance RRAM,(More)

We demonstrate compact integrated arrays of BEOL-friendly novel access devices (AD) based on Cu-containing MIEC materi-als[1-3]. In addition to the high current densities and large ON/OFF ratios needed for Phase Change Memory (PCM), scaled-down ADs also exhibit larger voltage margin Vm, ultra-low leakage (<10pA), and much higher endurance (>10 8) at high(More)

This paper focuses on the development of a new backcalculation method for concrete road structures based on a hybrid evolutionary global optimization algorithm, namely shuffled complex evolution (SCE). Evolutionary optimization algorithms are ideally suited for intrinsically multi-modal, non-convex, and discontinuous real-world problems such as pavement(More)
