Abstract: A composite tank for a reusable launch vehicle comprises a composite wall, having a first coefficient of thermal expansion. The composite wall comprises a first end, a second end, a central axis, which passes through the first end and through the second end, and a cylindrical interior surface. The composite tank also comprises slosh baffles, formed from a second material, having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. Each of the slosh baffles is attached to the cylindrical interior surface of the composite wall. Each of the slosh baffles is annular and is separated from the cylindrical interior surface of the composite wall by a radial gap, selected, in part, based on a difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion. The radial gap is configured to change responsive to changes in temperature of the composite tank.

Abstract: A method for dynamically allocating computing resources to virtual computing machines in a shared system. An initial allocation is made for each computing resource. Current demand for each computing resource for each of the virtual computing machines is determined to identify changes in current demand. The system identifies a virtual computing machine for which usage of a first computing resource is approaching a first predetermined threshold allotted to the first virtual computing machine. The system identifies a second virtual computing machine in the system for which usage of the first computing resource is less than a second predetermined threshold of the first computing resource allotted to the second virtual computing machine. The server dynamically allocates at least part of the first computing resource from the second virtual computing machine to the first virtual computing machine to meet current demand for the first computing resource in the first virtual computing machine.

Abstract: Described are systems and processes for generating dynamic effort-based delivery value predictions for real-time delivery of perishable goods. In one aspect, a system is configured for generating dynamic delivery value predictions for delivery opportunities provided to couriers. For each order, delivery events and corresponding timestamps are received from devices operated by customers, restaurants, and couriers. Based on the timestamps, the system generates a predicted delivery duration with trained predictive models that use weighted factors such as order data and historical restaurant data. A service value for the delivery of the order is determined based the predicted delivery duration and a predetermined active time value. The service value is then transmitted along with the corresponding delivery opportunity to a user device of a courier. The determined service values may be adjusted based on courier acceptance rates of delivery opportunities and other factors such as customer experience.

Abstract: A system for mitigating radio frequency interference includes a multiple patch antenna array including a multiplicity of patch antenna elements. The multiple patch antenna array is positioned relative to an interfering antenna such that signals from the interfering antenna cause interference with the multiple patch antenna array. The system also includes an auxiliary antenna positioned relative to the multiple patch antenna array. The system additionally includes a device to generate a spatial null in a direction to the interfering antenna from the multiple patch antenna array in response to a first signal from the auxiliary antenna and a second signal from the multiple patch antenna array. The first signal and the second signal are generated in response to a transmitted signal being received by the auxiliary antenna and the multiple patch antenna array. The spatial null permits simultaneous operation of the multiple patch antenna array and the interfering antenna.
