Abstract: A tactile device for correcting biomechanical abnormalities using physical virtual reality simulations includes an outer hollow sphere, a pliable inner hollow sphere, a plurality of actuators, and a framework. The plurality of actuators physically couple the outer hollow sphere to the pliable inner hollow sphere, and are configured to reshape the pliable inner hollow sphere as the outer hollow sphere and the pliable inner hollow sphere rotate. The framework includes a plurality of powered rollers which support the outer hollow sphere and control a rotational speed and direction of the outer and inner spheres. A set of pressure sensors detect pressure applied by a user against the pliable inner hollow sphere as the user moves within. One or more processors determine a biomechanical abnormality in the user based on pressure readings from the pressure sensors. A sphere controller then modifies a physical configuration of the pliable inner hollow sphere.

The plurality of actuators physically couple the outer hollow sphere to the pliable inner hollow sphere, and are configured to dynamically and physically reshape the pliable inner hollow sphere as the outer hollow sphere and the pliable inner hollow sphere rotate. The framework includes a plurality of powered rollers that support the outer hollow sphere and control a rotational speed and direction of the outer hollow sphere and the pliable inner hollow sphere.

Abstract: Workload distribution is automatically optimized. Cost penalty amounts imposed on executing a database operation transaction by current and alternative processing pathway options are determined as a function of execution response times that exceed a service level agreement time limit. Respective computer processing hardware costs are determined for executing the database operation transaction via each of the current and alternative processing pathway options. Respective licensing costs are determined for migrating execution of the database operation transaction to each of the alternative processing pathway options. Accordingly, the current or alternative middleware option that has a lowest total combined cost of licensing costs, computer processing hardware costs and service level agreement penalty costs is chosen as the path for execution of the database operation transaction.
