A system and method for conducting a multi-person, interactive auction, in a variety of formats, without using a human auctioneer to conduct the auction. The system is preferably implemented in software. The system allows a group of bidders to interactively place bids over a computer or communications network. Those bids are recorded by the system and the bidders are updated with the current auction status information. When appropriate, the system closes the auction from further bidding and notifies the winning bidders and losers as to the auction outcome.

A hydrogen-powered hybrid powertrain system includes a hydrogen-fuelled internal combustion engine operating at a lean air/fuel mixture, and a supercharger for boosting a primary drive torque produced by the engine primarily over a high operating speed range. An electric motor/generator generates a secondary drive torque for the vehicle, such that the secondary drive torque complements the boosted primary drive torque over at least a low operating speed range of the powertrain. A disconnect clutch disposed between the engine and the motor/generator engages and disengages the engine from the motor/generator, and serves to transfer the boosted primary driver torque through the motor/generator and to a power transmission system. The input at the power transmission is thus a combination of the boosted primary drive torque and the secondary drive torque having an enhanced torque characteristic over at least the low operating speed range.

The invention belongs to the information retrieval technology and provides a full-text retrieval system based on semantic analysis of relevant words. The full-text retrieval system based on semantic analysis of the relevant words comprises an inquiry information receiving module, a concept semantic analysis module based on the relevant words, a semantic knowledge base module, a retrieval module, an index database, an index module, a theme semantic analysis module based on the relevant words, a result set processing module and a data server. The full-text retrieval system based on semantic analysis of the relevant words is based on the improvement on a traditional Internet search engine, and by the adoption of the system, concept semantic analysis based on the relevant words and theme semantic analysis based on the relevant words of a document can be achieved, and users can obtain search results which are more accurate, more comprehensive and more intelligent.

The invention discloses a wireless communication method which comprises the following steps of: transmitting one or more communication frames between network equipment and terminal equipment, wherein each communication frame comprises a downlink subframe and an uplink subframe, and a guard interval is formed between the downlink subframe and the uplink subframe; and dynamically configuring structures of the downlink subframe and the uplink subframe in each frame in a process of transmitting the one or more communication frames, wherein a dynamically configured downlink subframe at least comprises a leading sequence, a system information channel, a control channel and a downlink transmission channel, and a dynamically configured uplink subframe at least comprises an uplink transmission channel. The invention also discloses a wireless communication system. The frame structure is dynamically configured, so that uplink and downlink wireless transmission resources can be dynamically allocated based on service requirements, and future data service requirements with rich kinds and different characteristics can be well dynamically met.

The invention discloses a taxi GPS (Global Positioning System) record based airport bus station and path planning method. The taxi GPS record based airport bus station and path planning method comprises the following steps of step 1 obtaining a data set; step 2 filtering all taxi GPS records through a data filter algorithm; step 3 classifying the filtered data set for an airport according to pick and drop sites, wherein the data set is divided into an airport entering data set and an airport leaving data set; step 4 clustering PDRs (Pick/Drop Records) entering the airport entering data set through a cluster algorithm and obtaining a cluster center and a clustering set, wherein a cluster center set is an airport bus candidate station; step 5 performing correcting optimization on the candidate station according to a station setting rule and an optimized algorithm; step 6 planning an airport entering path for an airport bus through a path planning algorithm for an optimized station; step 7 repeating the step 4,5 and 6 for the airport entering and leaving sets to obtain an airport leaving bus path planning scheme for the airport bus.

Certain embodiments disclosed herein provide devices, systems, and methods of using location-based virtual audience feedback to estimate interest in an attraction at one or more venues. Certain embodiments provide devices, systems, and methods of using location-based virtual audience feedback and/or other audience data to estimate interest in a plurality of attractions or other items of interest at a particular venue. Some embodiments relate to matching techniques that use virtual feedback to estimate demand for a match. Examples of matches include a match between an attraction and a venue, a candidate for a government position and a constituency, a player and a sports team, a film and a theater, and a retail good and a shelf location.
