Abstract: The present invention includes a catalyst that has at least four layers, (1) porous support, (2) buffer layer, (3) interfacial layer, and optionally (4) catalyst layer. The buffer layer provides a transition of thermal expansion coefficient from the porous support to the interfacial layer thereby reducing thermal expansion stress as the catalyst is heated to high operating temperatures. The method of the present invention for making the at least three layer catalyst has the steps of (1) selecting a porous support, (2) solution depositing an interfacial layer thereon, and optionally (3) depositing a catalyst material onto the interfacial layer; wherein the improvement comprises (4) depositing a buffer layer between the porous support and the interfacial layer.

Abstract: The invention relates to cardiovascular protheses with a stable, confluent endothelial cell surface which is produced by proliferation under a shearing stress. Said cardiovascular protheses are produced by means of a novel method for creating a stable confluent endothelial cell monolayer. The inventive cardiovascular protheses ensure markedly improved bonding of the cells on the surface of the prosthesis and hereby enable the monolayer to be obtained even over long periods and in more demanding shearing stress conditions. The invention hereby provides the first means of significantly reducing the risk of coagulation compared to non-covered prostheses which are not confluently lined with endothelial cells and prostheses which have not been confluently populated but whose cells do not bond sufficiently on the surface.

Abstract: A human speech detection method detects pure-speech signals in an audio signal containing a mixture of pure-speech and non-speech or mixed-speech signals. The method accurately detects the pure-speech signals by computing a novel Valley Percentage feature from the audio signal and then classifying the audio signals into pure-speech and non-speech (or mixed-speech) classifications. The Valley Percentage is a measurement of the low energy parts of the audio signal (the valley) in comparison to the high energy parts of the audio signal (the mountain). To classify the audio signal, the method performs a threshold decision on the value of the Valley Percentage. Using a binary mask, a high Valley Percentage is classified as pure-speech and a low Valley Percentage is classified as non-speech (or mixed-speech). The method further employs morphological filters to improve the accuracy of human speech detection. Before detection, a morphological closing filter may be employed to eliminate unwanted noise from the audio signal. After detection, a combination of morphological closing and opening filters may be employed to remove aberrant pure-speech and non-speech classifications from the binary mask resulting from impulsive audio signals in order to more accurately detect the boundaries between the pure-speech and non-speech portions of the audio signal. A number of parameters may be employed by the method to further improve the accuracy of human speech detection. For implementation in supervised digital audio signal applications, these parameters may be optimized by training the application a priori. For implementation in an unsupervised environment, adaptive determination of these parameters is also possible.

Abstract: The method for detecting and locating leaks in a geo-membrane lined facility containing liquids, sludges, or soils, using an excitation of the mass (mise-a-la-masse) electrical resistivity technique and an electrode array, comprises placing a number of electrical potential sensing electrodes in soil located peripherally outside the lined facility. A first set of electrical potential measurements is made on combinations of the sensing electrodes using a first sensing electrode pair as a current injection pair and a second sensing electrode pair as an electrical potential measurement pair. An electrical resistivity distribution is mapped under the lined facility, and is derived from the first set of electrical potential measurements by performing a mathematical inversion on same. An electrical current is injected into the liquid, sludge, or solid using an injection electrode located within the lined facility and a sink electrode located in an area outside of the lined facility. A second set of electrical potential measurements is made on combinations or the sensing electrodes located peripherally outside the lined facility. The second set of electrical potential measurements is analysed using mathematical inversion techniques to locate the leaks in the lined facility. The leak position is located by determining the coordinates of an electrical current source pole that best fits the measured potentials with the constraints of the known or assumed resistivity distribution.
