The invention relates to methods and systems for providing investment competitions. In one aspect, trading algorithms that automatically generate trading instructions in response to market data are developed by and received from a distributed plurality of independent trading algorithm developers. The algorithms are periodically executed against market data and generate trading instructions, which, based on an association of investment accounts with the trading algorithms, initiate correlative trades in the investments accounts.

A vehicular “black box” provides recording means by which driver action can be reviewed after an accident or collision, as well as indicating immediate vehicle disposition status to the driver. Using cameras (which may be very small), the disposition of the vehicle in its lane is determined by detecting the highway lines painted on the road. The data is also recorded so that should an accident or collision occur, the events leading up to such an event are made available for later review and analysis.

Embodiments described herein provide a system, method and computer program for dynamic radio map generation, which may be used for indoor positioning of one or more mobile devices based on received signal strength (RSS) in some examples. In an aspect, a dynamic scheme may be used to learn the RSS radio map from only a small number of fingerprint samples. Compressive sensing may be applied to build the graph structure and calculate the graph weight in some embodiments. Once the RSS radio map is learned, a mobile device may be located and location based services can be provided to the user in some example embodiments. An indoor learning and positioning system on a mobile device may be used to evaluate the performance. Embodiments described herein may not require a large amount of offline calibrations, which may reduce the labor cost of collecting fingerprints significantly while maintaining a satisfactory level of localization accuracy.

The embodiment of the invention discloses a delivery device, which comprises an outer delivery tube, a push rod, an inner tube, a functional handle and a plurality of connecting tubes, wherein one end of each connecting tube is connected with the push rod; the tube cavities of the connecting tubes are communicated with a metal wire passage in the push rod; the other ends of the connecting tubes are provided with connecting grooves; and the connecting grooves are communicated with the tube cavities of the connecting tubes. The connecting grooves are used for connecting the connecting port of a heart valve and the connecting tubes, and metal wires pass through the connecting port and are kept in the tube cavities of the connecting tubes, so that the metal wires are connected with the heart valve. The heart valve is fixed through the metal wires and the connecting grooves; when the heart valve is released, the metal wires must be extracted from the connecting grooves to finish release of the heart valve; therefore, before the heart valve is totally separated from the delivery device, the delivery device can be connected with the heart valve and can reclaim and reset the heart valve. The invention also discloses a heart valve delivery system.

A building response function defining a response of a building to specific environmental change, e.g., occurrence of a fire, in terms of the building structure, is stored in a computer. Also stored is a refuge motion function defining the refuge motion of individuals in terms of attributes of the individuals and the building response. The building response is computed by substituting design values of the building structure into the response function. Attributes of persons are inputted to the computer, and individuals' refuge motion is computed by using both inputted attributes and the computed building response. With the inputted and computed values, three-dimensional (3D) simulation images of the building structure, of the building response, and of individuals' refuge motion are computed. Then, a superposed 3D simulation image of the three images is displayed to facilitate analysis of the building performance.

The quality and reliability of electro-optical modules can be improved, for instance, through improved testing and burn-in of an electro-optical sub-assembly. Reliability can also be enhanced through better methods of constructing an electro-optical module. By arranging both an electrical interface and an optical interface on a sub-assembly, for instance, testing can be performed on both interfaces in a single testing process. Burning-in an electro-optical sub-assembly can also improve the reliability of the module by identifying defects. A method of forming an electro-optical module can provide improved reliability by testing and / or burning-in an electro-optical sub-assembly before assembling the module.
