Standard noise compensation techniques for automatic speech recognition assume a clean trained acoustic model. What is thought of as "clean" data, may still have a variety of speakers, different channels and varying noise conditions. Hence it may be more reasonable to consider such data multi-conditional for multistyle training. This paper shows that multistyle models benefit from VTS compensation...
Osteoblasts and adipocytes are two differentiated cell types which are both derived from mesenchymal stem cells (MSCs) and a reciprocal relationship may exist between osteoblastogenesis and adipogenesis in the bone marrow. Our previous studies in the mouse have indicated that low-magnitude, high-frequency mechanical stimuli can stimulate bone formation. To investigate whether lipid metabolism gene...
The failure-in-time (FIT) rate is widely used to quantify the reliability of a electronic component. It fails to indicate the portion of the failures due to either environmental or electrical stresses or issues that are related to process/handing, manufacturing and applications. To meet this end, FIT-based corrective action driven metrics are proposed to link the failure mode (FM) with components...
This paper proposes a novel wafer-level packaging (WLP) method at room temperature for piezoresistive pressure sensors. We use a polydimethylsiloxane (PDMS) sheet as a candidate for replacing a Pyrex glass wafer, to seal the backside V-grooved chambers of the pressure sensor chips. PDMS is a well-known material in MEMS technology recently. It is not only cheap but also has a merit of a simple process...
We propose a new opto-plasmonic tweezer for trapping and fine orientation control of micro/nano objects. The device utilizes polarized light to excite resonant dipoles on the surface of an Au nanoparticle array. The large dielectrophoresis force is then created by the highly non-uniform optically induced dipole field. The orientation control is realized by adjusting the polarization direction of the...
This paper presents a low-power and high-gain 5.7 GHz CMOS double-balanced mixer for an IEEE 802.11a WLAN application. The RF input frequency of the mixer is 5.725 ~ 25 GHz, LO is 5.265 ~ 5.325 GHz, IF is at 480 MHz. The mixer is fabricated with the 0.18 mum 1P6M standard CMOS process. The die size is 0.627 times 0.649 mm2. The measurements are performed using an FR-4 PCB test fixture. The fabricated...
Internet protocol (IP) networks were originally designed by universities and government research agencies, not by network operators with commercial objectives. As a result, while aggregate accounting is possible for network management, detailed accounting at the level of individual users is often not possible. In today's networks, this limitation hinders the effective introduction of a variety of...
