Well-aligned Cu-doped ZnO nanorods were successfully synthesized on polyethylene terephthalate (PET) substrate using chemical bath deposition method. The structural and optical properties of Cu-doped ZnO nanorods were investigated using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX) and photoluminescence (PL) spectroscopy...

Due to our limited knowledge about silicon carbide metal–oxide–semiconductor fieldeffect transistors (SiC MOSFETs), the theoretical analysis and change regularity in terms of the effects of temperature on their switching characteristics have not been fully characterized and understood. An analysis of variation in voltage (dVDS/dt) for SiC MOSFET during turn-on and turn-off has been performed th...

The switched reluctance motor is a singly excited, doubly salient machine which can be used in generation mode by selecting the proper firing angles of the phases. Due to its robustness, it has the potential and the ability to become one the generators to be used in harsh environment. This paper presents an energy conversion by a Switched Reluctance Generator (SRG) when bifilar converter ci...

STEP-NC (ISO 14649) is becoming a promising standard to replace or supplement the conventional G-code programs based on ISO 6983 due to its feature based machine independent characteristics and its centric role to enable efficient CAD/CAM/CNC interoperability. The re-use of Gcode programs is important for both manufacturing and capitalization of machining knowledge, nevertheless the conversion ...

In this paper we report on our work on a prototype route navigation dialogue system for use in a vehicle. The system delivers spoken turn-by-turn directions, and has been developed to accept naturally phrased navigation queries, as part of our overall effort to create an in-vehicle information system which delivers information as requested while placing minimal cognitive load on the driver.

Continuously scaling down and decreasing operation voltages of ICs, from the 5 V TTL-compatible voltage to 3.3 V, then 1.2 now 0.8 for low-power results in more stringent electrostatic discharge protection design requirements, such as a narrow ESD window, low voltage, high robustness. Based on traditional diode string diode-triggered silicon-controlled rectifiers, an enhanced rectifier is propo...

In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...
