Abstract: A method for creating, sharing, combining, and analyzing musical multimedia play lists based on a user contextual classification. Musical multimedia is media that utilizes a combination of different content forms such as music songs, movies, pictures, and sounds. This contextual classification is defined by relationships among key elements of the multimedia content. For example, the relationships for music songs are defined among musical genre, singer/player, or a specific music song with an activity list, places or locations, and states of feeling (i.e., mood or temper) defined by the user when he usually listens to music frequently.

Abstract: A computer-implemented method capable of identifying, activating, and executing commands, methods, functions, interfaces, and software-based applications that can satisfy a specific natural language user request represented by a text stream and generated from any means such as typing, voice, gestures, signs or by human thoughts.

Abstract: A method of drilling a well using at least one drill bit and at least one secondary cutting structure, that includes determining a neutral point of a drill string positioning at least one secondary cutting structure based on the neutral point of the drill string, and drilling an earth formation.

Abstract: A method for improving drilling performance of a drilling tool assembly is disclosed. The method includes identifying a drilling performance parameter to be improved. One or more potential solutions are defined to improve the drilling performance parameter. A drilling simulation is performed to determine the dynamic response of the drilling tool assembly during a drilling operation. Determining the dynamic response includes determining the interaction of a cutting element of a drill bit with an earth formation. Improvement in the drilling performance parameter is determined based upon the drilling simulation.

Abstract: Methods and computer systems for performing and using drilling simulations. The drilling simulations can be used to improve drilling performance or demonstrate drilling performance of a drilling profile. One method for creating a drilling profile includes obtaining drilling profile data and performing a drilling simulation using at least a portion of the drilling profile data. Modifications are then recommended for the drilling profile data.
