  • A P-ORDER METRIC UWB RECEIVER STRUCTURE WITH IMPROVED PERFORMANCE IN MULTIPLE ACCESS INTERFERENCE-PLUS-NOISE MULTIPATH CHANNELS
    Publication number: 20100074307
    Abstract: A UWB receiver dubbed the “p-order metric” receiver (p-omr) is proposed to detect the time-hopping ultra-wide bandwidth signal in multiple access interference channels. The receiver acquires a signal over a wireless channel, adaptively selects a shaping parameter, p, over time and generates a first set of partial statistics by, for each of a plurality N of observations per symbol, using the shaping parameter to modify the exponential order of the approximation of the noise plus multiple access interference probability density function, f(x), used in the receiver model.

  • SYSTEM AND METHOD FOR RECEIVING TIME-HOPPING ULTRA-WIDE BANDWIDTHS SIGNALS
    Publication number: 20100008401
    Abstract: A novel receiver structure is proposed for detecting a time-hopping ?ltrat-wide bandwidth signal in the presence of multiple access interference. The proposed structure achieves better bit error rate performance than the conventional matched receiver when operating in multiple access interference. When operating in a multiple access interference-plus-Gaussian-noise environment, the receiver structure outperforms the conventional matched filter receiver for moderate to large values of signal-to-noise ratio. A receiver structure with adaptive limiting threshold is further proposed to ensure the performance of the soft-limiting receiver always meets or surpasses the performance of the conventional UWB receiver for all values of signal-to-noise ratio.

  • APPARATUS AND METHODS FOR LIQUID DROPLET DEPOSITION
    Publication number: 20090302208
    Abstract: A method of and an apparatus for generating droplets has a capillary tube mounted in a moveable member. The capillary tube is accelerated towards a plate, and then subject to rapid deceleration, e.g. by way of an impact, to promote separation of a droplet which is then deposited on the plate. The droplet can be entirely separated from the capillary tip before being deposited, or, for smaller droplets, the droplet merely extends from the capillary tip and is then drawn onto the plate by a wicking action. The plurality of capillary tubes can be mounted on the common support member to effect multiplexing of drops.

  • PROCESS FOR EXTRACTION OF BITUMEN FROM OILSANDS
    Publication number: 20090288994
    Abstract: Bitumen within raw oilsands may be cracked and fully recovered by light hydrocarbon extraction following exposure to modified natural zeolite catalysts under cracking conditions. The recovered bitumen is reduced in viscosity, with lower boiling point distributions. Effective cracking of oilsands bitumen using economical, abundant and readily disposable natural zeolites represents a significant step towards a waterless and environment friendly extraction process.

  • Decision-Feedback Detection for Block Differential Space-Time Modulation
    Publication number: 20090262869
    Abstract: Time variation on fading channels hinders accurate channel estimation in differential space-time modulation and deteriorates the performance. Decision-feedback differential detection is employed for block differential space-time modulation, and compared with conventional differential space-time modulation. It is observed that the proposed scheme does not suffer effective fading bandwidth expansion, as does the conventional scheme. An improved effective signal-to-noise ratio approach is proposed for analyzing the performance of the proposed scheme in time-varying flat Rayleigh fading. Theoretical analysis and simulations show the improved performance of the proposed scheme over the conventional scheme.

  • ANALYSIS OF THIN LIQUID FILMS
    Publication number: 20090243635
    Abstract: A novel microfluidic device has been developed to measure stability of thin liquid films of water in oil emulsions using electrochemical perturbation of interfaces. This new device can be utilized in rapid classification of de-emulsifiers used in petroleum industries. Although water/crude oil emulsions have been the primary focus of this research, this measurement platform can be used in other industries such as food, cosmetics and bio-engineering (bilayer lipid membranes) as well as environmental remediation of oil spills. The compact design of the device and replacement of the mechanical measurements such as pressure with electrical signal measurements contributes in substantial size reduction of the experimental platform so that it can be employed for onsite measurements in remote areas.
