20080279751 | METHOD FOR PREPARING UNIFORM SINGLE WALLED CARBON NANOTUBES - Methods of preparing single walled carbon nanotubes from a metal catalyst having deposited thereon fullerenes are provided. Fullerenes are deposited onto a metal catalyst precursor or metal catalyst. In the presence of a carbon containing gas, the metal catalyst precursor/fullerene composition is then exposed to conditions suitable for reducing the metal catalyst precursor, for subliming the fullerene and for growing single walled carbon nanotubes. The fullerenes form the end caps for the resulting single walled carbon nanotubes, which are uniform in diameter. | 11-13-2008 |
20090093360 | METHOD FOR PREPARING CATALYST SUPPORTS AND SUPPORTED CATALYSTS FROM SINGLE WALLED CARBON NANOTUBES - A new method for preparing a supported catalyst is herein provided. A carbon nanotube structure such as a rigid porous structure is formed from single walled carbon nanotubes. A metal catalyst is then loaded or deposited onto the carbon nanotube structure. The loaded carbon nanotube is preferably ground to powder form. | 04-09-2009 |
20090286084 | Method for Preparing Single Walled Carbon Nanotubes from a Metal Layer - Methods of preparing single walled carbon nanotubes are provided. An arrangement comprising one or more layers of fullerene in contact with one side of a metal layer and a solid carbon source in contact with the other side of metal layer is prepared. The fullerene/metal layer/solid carbon source arrangement is then heated to a temperature below where the fullerenes sublime. Alternatively, a non-solid carbon source may be used in place of a solid carbon source or the metal layer may simply be saturated with carbon atoms. A multiplicity of single walled carbon nanotubes are grown on the fullerene side of the metal layer, wherein at least 80% of the single walled carbon nanotubes in said multiplicity have a diameter within ±5% of a single walled carbon nanotube diameter D present in said multiplicity, said diameter D being in the range between 0.6-2.2 nm. | 11-19-2009 |

20150221218 | Predictive Incident Aggregation - In one embodiment, an incident report including a path segment identifier and an incident identifier is received at a computing device. The incident identifier is sent to a traffic prediction model. The traffic prediction model returns a traffic distribution value. The traffic distribution value identifies a portion of a traffic prediction distribution derived from historical data. The computing device accesses a lookup table according to traffic distribution value and the path segment identifier to receive a speed prediction. | 08-06-2015 |
20150242868 | METHOD AND APPARATUS FOR CAUSING A RECOMMENDATION OF A POINT OF INTEREST - An approach is provided for determining at least one distribution of a plurality of current values for at least one dynamic content parameter associated with a plurality of points of interest within a predetermined proximity to at least one target point of interest. The approach involves determining at least one distribution mean and at least one distribution standard deviation for the at least one distribution of the plurality of current values. The approach also involves determining at least one set of historical values for the at least one dynamic content parameter for the at least one target point of interest. The approach further involves determining at least one estimated current value for the at least one dynamic content parameter associated with the at least one target point of interest based, at least in part, on the at least one set of historical values, the at least one distribution mean, and the at least one distribution standard deviation. | 08-27-2015 |
20150300835 | METHOD AND APPARATUS FOR CREATING AN ORIGIN-DESTINATION MATRIX FROM PROBE TRAJECTORY DATA - An approach is provided for creating an origin-destination matrix from probe trajectory data. The approach includes receiving probe trajectory data, wherein the probe trajectory data is associated with at least one subset of a plurality of travel nodes. The approach further includes processing and/or facilitating a processing of the probe trajectory data to construct one or more microscopic origin-destination matrices, wherein the at least one microscopic origin-destination matrix represents one or more preferred travel paths through the subset of the plurality of travel nodes. The approach also involves causing, at least in part, an aggregation of the one or more microscopic origin-destination matrices to construct at least one aggregated origin-destination matrix to represent the plurality of travel nodes. | 10-22-2015 |
