The present invention relates to a device and a method associated with helping blind dogs navigate. With respect to the device, it is a set of one or more sensors and stimulators, which provide situational awareness to a blind dog regarding objects and sudden drops in its vicinity, helping the dog freely move about without the risk of collision or fall. The core components of the invention are a distance sensor, a microcontroller, a tactile/audio stimulator, an accelerometer, a power source, a control panel, a body harness, and a head wrap, which, generally speaking, are configured as follows: a frontal distance sensor mounted on top of a blind dog's head using the head band, the lower distance sensor, the stimulators, the microcontroller, the accelerometer, the power source, and the control panel are mounted on the blind dog using the body harness. With respect to the associated method, in order to carry out the method the following core steps are followed: a frontal distance sensor method to detect the objects in front of the blind dog and alert the blind dog when a collision is imminent, a drop sensor method to detect sudden drops in front of the blind dog and alert the dog when a fall is imminent, a velocity calibration method and a velocity computation method determine the movements of the dog based on accelerometer signals, and a velocity compensated alert method adjust and increase the alert distance/time when the dog is moving toward an obstacle or a drop.

System and methods of modeling casing deformation for hydraulic fracturing design are provided. A three-dimensional (3D) global model of a subsurface formation is generated. Values of material parameters for different points of the subsurface formation represented by the 3D global model are calculated based on a geomechanical analysis of well log data obtained for the subsurface formation. The calculated values are assigned to corresponding points of the global model. A 3D sub-model of a selected portion of the formation including a casing to be placed along a planned trajectory of a wellbore is generated based at least partly on the values assigned to the global model. Numerical damage models are applied to the global model and sub-model to simulate effects of a hydraulic fracturing treatment on the formation and casing along the planned wellbore trajectory. Casing deformation along the planned wellbore trajectory is estimated, based on the simulation.

A system and method for performing stimulation operations at a wellsite having a subterranean formation with of a reservoir therein is provided. The method involves generating a plurality of quality indicators from a plurality of logs, and combining the plurality of quality indicators to form a composite quality indicator.

A system, method and apparatus for executing a sequence analysis pipeline on genetic sequence data includes an integrated circuit formed of a set of hardwired digital logic circuits that are interconnected by physical electrical interconnects. The hardwired digital logic circuits are arranged as a set of processing engines, each processing engine being formed of a subset of the hardwired digital logic circuits to perform one or more steps in the sequence analysis pipeline on the reads of genomic data. In various instances, each subset of the hardwired digital logic circuits may be formed in a wired configuration to perform one or more steps a variant call operation.

A method and apparatus for generating a simulation grid for a reservoir model based on a geological model comprising horizons, constraints and multiple geological grid cells. A pre-image is generated corresponding to the geological grid cells, the pre-image comprising a surface and the modeling constraints being mapped onto the surface. A constrained two-dimensional grid is generated on the pre-image, the two-dimensional grid comprising multiple grid cells. Simulation layer boundaries are selected from the geological model and the constrained two-dimensional grid is projected onto the simulation layer boundaries. Prismatic cells are then generated to form the three-dimensional simulation grid. The method of generating a grid as herein described may be incorporated in existing reservoir simulators.

Conventional systems for monitoring pipe networks are generally not scalable, impractical in the field with uncontrolled environments or rely of static features of pipes that are vary depending on the pipes under consideration. The ideal sensor-ed monitoring systems are not economically viable. Systems and methods of the present disclosure provide an improved data-driven model to rank pipes in the order of burst probabilities, by including dynamic feature values of pipes such as pressure and flow that depends on network structure and operations. The present disclosure enables estimating approximate values for the dynamic features since they are hard to estimate accurately in the absence of a calibrated hydraulic model. The present disclosure also validates the estimated approximate dynamic feature values for the purpose of estimating bursts likelihood vis-a-vis accurate values of the dynamic metrics.
