Abstract: A system and method control a water resource infrastructure (WRI). The WRI has infrastructure components that are actuatable to cause a change to the WRI. A monitoring system has sensors that collect operating data that describes a state of the infrastructure components. A disturbance data provider provides disturbance data that may be expected to have an impact on operational parameters of the infrastructure components. A control mechanism scheduler receives the disturbance data and the operating data, trains to generate a schedule of setpoints for a control system in accordance with approaching a predetermined objective, and retrieves and outputs the schedule of setpoints in response to receiving real-time operational data. A control system receives the schedule of setpoints controls the infrastructure components based thereon.

Abstract: In various embodiments, a training application generates a trained encoder that automatically generates shape embeddings having a first size and representing three-dimensional (3D) geometry shapes. First, the training application generates a different view activation for each of multiple views associated with a first 3D geometry based on a first convolutional neural network (CNN) block. The training application then aggregates the view activations to generate a tiled activation. Subsequently, the training application generates a first shape embedding having the first size based on the tiled activation and a second CNN block. The training application then generates multiple re-constructed views based on the first shape embedding. The training application performs training operation(s) on at least one of the first CNN block and the second CNN block based on the views and the re-constructed views to generate the trained encoder.

The design objectives indicate a specific type of topology that is derived from an existing urban layout. The design heuristics include different sets of construction rules for generating designs with specific types of topologies. The geometry engine generates candidate designs that conform to the property boundary and have topological characteristics in common with the existing urban layout.

Abstract: A method and system provide the ability to design a space in a computer-aided design (CAD) application. A 3D model is acquired. The space is designed by defining Elements including a parent and a child element. Each Element encapsulates a geometric model, and consists of metadata that provides a summary of contents in each Element that enables an outside process to handle each Element without access to the encapsulated geometric model. An arbitrary logic Program is structured to generate a list of the child Elements. The 3D model is edited and updated in real time. During the updating, the Program is reexecuted to update the child elements while attempting to conserve a hierarchical structure of the Elements. The updated 3D model is provided via a graphical user interface that enables editing of the geometric model and the Elements in the space.

Abstract: A method and system provide for augmenting a photograph. An unlabeled photograph is obtained. A weakly augmented photograph and a strongly augmented photograph are obtained from the unlabeled photograph based on different types of data augmentation methods. The weakly augmented photograph is processed through a model to generate multiple weakly augmented photograph class predictions (with assigned probabilities). The multiple weakly augmented photograph class predictions are converted into positive pseudo-labels (indicating a presence of a class) or negative pseudo-labels (indicating absence of a class) using different fixed percentile thresholds. The strongly augmented photograph is processed through the model to generate a strongly augmented photograph class prediction. The model is trained to make the strongly augmented photograph label prediction match the positive pseudo-label via a cross-entropy loss. The trained model is then utilized to label the unlabeled photograph with multiple labels.

Abstract: A hybrid workstation enables a virtual reality (VR) interface, a traditional (TD) interface, and transitions between the interfaces. The VR interface comprises three-dimensional (3D)-based software and hardware components. The TD interface comprises two-dimensional (2D)-based software and hardware components. The state of the hybrid workstation is defined by three parameters comprising interface (VR interface or TD interface), position (seated or standing), and movement (stationary or room-scale). The hybrid workstation detects a transition from a current state to a next state upon determining that any of the three parameters have changed. The hybrid workstation then determines a transition response based on the particular transition that is detected. The transition response comprises a set of operations that are performed on the VR interface and/or the TD interface that mitigate the disruption and inefficiency caused when the particular transition occurs.

Abstract: A finger device initiates actions on a computer system when placed in contact with a surface. The finger device includes instrumentation that captures images and gestures. When in contact with a surface, the finger device captures images of the surface and gestures made on the surface. The finger device also transmits the images and gesture data to the computer system. An application on the computer system matches the images received from the finger device to a representation of the surface, identifies an action associated with the surface representation and gesture, and executes the action. Instrumenting the finger instead of the surface, allows a user to configure virtually any surface to accept touch input.
