Abstract: A calibration method for an x-ray computerized tomography system and a method of tomographic reconstruction are provided. The calibration method includes steps of measuring at least one point spread function (PSF) at each of a plurality of points, compressing each PSF, and in one or more storing operations, storing the compressed PSFs in a computer-accessible storage medium. The PSF measurements are made in a grid of calibration points in a field of view (FOV) of the system. In the measuring step, an absorber is positioned at each of the calibration points, and an x-ray projection is taken at least once at each of those absorber positions. In the method of tomographic image reconstruction, projection data from an x-ray tomographic projection system are input to an iterative image reconstruction algorithm.

Abstract: In some aspects, a first plug-in module that is installed on a server receives an instruction to install a particular database on a first target server that is near (e.g., less than a threshold number of hops from or having less than a threshold latency communicating with) the server. The first plug-in module creates a first persistent authentication session between the server and the first target server and initiates a first installation of a first database on the first target server using the first persistent authentication session. Concurrently with the first installation, a second plug-in module that is installed on a second server initiates a second installation of a second database on a second target server using a second persistent authentication session. The second target server is near the second server.

Abstract: A device and method determines available regenerative braking energy in a route for a target vehicle. The device is in communication with a navigation unit and is configured to split the at least one route between a source and a destination into multiple segments followed by determining vehicular data of the target vehicle. The device determines available/recoverable regenerative braking energy in the at least one route for the target vehicle based on selective vehicular data of other vehicles similar to the target vehicle, which have travelled through the at least one route. The device is configured to dynamically predict the available regenerative braking energy originating from random longitudinal deceleration maneuvers for the chosen route from source location to the chosen destination location for any hybrid or electric vehicle. The device improves fuel efficiency and reduces emissions.

Abstract: A temperature sensor detects temperature of ink to be supplied to a plurality of nozzles. When, upon receiving a print request, a detection temperature detected by the temperature sensor is lower than a reference temperature, a control portion executes a preliminary vibration control to cause an ink meniscus oscillation to occur in each of the nozzles by vibrating the piezoelectric elements, and after the detection temperature increases up to the reference temperature, executes an ink ejection control to cause the ink to be ejected from the nozzles by vibrating the piezoelectric elements in correspondence with an output target image of a print request. When, upon receiving the print request, the detection temperature is higher than the reference temperature, the control portion executes the ink ejection control without executing the preliminary vibration control.

Abstract: A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A camera assembly is used to monitor articles for washing within the wash basket. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain a reference image and one or more test images, which utilize image recognition to assess turn-over of the articles for washing during a given wash cycle. When turn-over performance is inadequate, a controller may adjust one or more operating parameters of the wash cycle to improve performance. Turn-over performance of the wash cycle is determined to be adequate once the image recognition process fails to find adequate correlation between the reference image and the test image a predetermined number of times.
