Title: System and method for conducting product configuration research over a computer-based network
Inventor: JEAVONS ANDREW P
IPC: G06Q30/02
Filed: 2002-06-14
Abstract: A system and method is provided for enabling respondents at their computer systems to connect with a server computer over a network, such as the Internet, and receive an executable configuration program enabling each respondent to select for each of the features of a product one of multiple subfeature attributes or levels for that feature. Each of the subfeatures fo r each feature has a price value and the combination of selected subfeatures f or the features of the product provides a total price value of the product. The total price value is displayed and updated as subfeatures for the features a re selected by the respondent or the selection of subfeatures are changed by th e respondent. When the total price value of the product is acceptable to the respondent, and subfeatures have been selected for each feature of the product, the program returns configuration information to the computer serve r having data representing the subfeatures selected for the product, the total price of the product, the time for the respondent to complete the configuration of the product, and each of the features and subfeatures selected and changed by the respondent in arriving at the final configured product. The configuration program may be part of a survey being conducted over the network by the server computerin which questions of the survey following receipt of the configuration information by the computer server ma y be in accordance with such configuration information.

Patent CA-2453711-A1 (CA)
Inventor: GAZOR SAEED
IPC: H04B17/00
Filed: 2003-12-17
Abstract: System and methods are provided based on optimization of the weighted log-likelihood. These systems are able to efficiently track dominant sinusoidal components of a real signal in Gaussian noise, provided that the number of the components is known. The algorithm is implemented using simple parallel building blocks involving narrow-band filters that are adaptively self-tuned around the frequencies of the signal components. The algorithm has low computational complexity and provides high estimation accuracy and is also able to track chirp signals. The algorithm is flexible enough to be adjusted to operate in different environments such as for speech signals, by selecting a proper window function. Simulation results confirm that the proposed algorithm is reliable in tracking the frequencies as well as in estimation of the amplitudes of the components. In a chirp environment, the algorithm is able to recognize some frequency cross-ovens as long as the amplitudes are different enough around the cross-over moment. Simulations show that the LIR of the algorithm is not affected by the SNR and is inversely proportional to the window length. The effects of the length and type of the window on the frequency resolution and the LIR of the algorithm are discussed. The algorithm is efficiently capable of decomposing speech voiced signals.

IPC: C07B61/00
Filed: 2003-02-25
Abstract: The invention relates to the production of shell catalysts, which contain at least one catalytically active metal on an inorganic or carbon support. These shell catalysts are produced by mixing a solid, preferably vaporizable, precursor material of the at least one catalytically active metal with the inorganic support and heating this mixture while continually mixing the same until separate solid precursor material is no longer present, preferably to a temperature at which the precursor material vaporizes. Shell catalysts of this type can be used, in particular, in hydrogenations.
