Abstract: A processor tracks a frequency of access requests of a first index corresponding to a first data page of a plurality of data pages stored in a database. The processor determines the first index corresponding to the first data page having a frequency of access requests that exceeds a configurable target, and the processor retains, with preference, the first data page that corresponds to the first index, within the cache memory.

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.

Abstract: A tactile device for 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 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. A sphere controller then modifies a physical configuration of the pliable inner hollow sphere based on a detected biomechanical abnormality of a user within the tactile device.

Abstract: An approach to generating a disruption indicator for an employee. The approach parses communication feeds into a collection of verbs and subjects. The approach then uses a lookup to determine if the verbs match actions associated with stressful situations. Further, the approach determines the location of the employee based on GPS coordinates to aid in measuring a stressful situation. The approach then stores the data for further analysis and generates a disruption indicator for the employee. The approach can also tune the disruption indicator by weighting the assessment of the stressful situation with the employee's biometric data from the time of the stressful situation.
