Abstract: Provided are methods, devices, and non-transitory computer-readable storage mediums to generate an itinerary with a weather forecast. The itinerary may comprise a departure location, a destination location and a first time. Based on the itinerary, an intermediary location and an intermediary time associated with the intermediary location may be identified. A weather forecast associated with the identified intermediary location and the intermediary time may be predicted. A weather risk associated with the identified route may be assessed and. based on the assessed risk, an alternative route may be additionally identified.

Abstract: The present document describes a method for generating and displaying a succession of short-term weather forecasts, also called nowcasts, in selectable time increments. A system for preparing nowcasts, called nowcaster, is used for preparing short-term forecasted weather values with a default time increment between each one of them. The method receives a chosen time increment from a user and the prepared forecasted weather values. The method comprises an aggregator that re-packages the forecasted weather values in the chosen time increments. A succession of short-term weather forecasts, which is a collection of forecasted weather values at the chosen time increment, is then outputted.

Abstract: Provided are methods, devices and non-transitory computer readable storage mediums to generate a more accurate weather forecast by utilizing actual observation of a weather event in a particular location and time. For example, the observation data may be received from a user device and contain information indicative of a weather event that the user observed. Alternatively, or additionally, the observation data may be automatically generated by one or more sensors placed in certain locations and transmitted to a central server automatically upon detecting an observation. The observation data may be used to predict a weather forecast of a location that corresponds to, or is otherwise related to the particular location in which the observed event occurred.

Abstract: A system and method for displaying nowcasts along a route on a map. The system receives a map request including a departure location and a destination location from a user, and obtains map data including a route between the destination location and the departure location. A nowcaster is used for outputting nowcasts for a number of key points along the route. The system modifies the map data to include a visual indicator for each nowcast for each key point such that when the modified map data is executed on a display the nowcasts are displayed along the route between the departure location and the destination location.

Abstract: A system and method for generating nowcasts for a given location over a period. The system receives weather observations and predictions for the given location from a plurality of weather sources, and processes this information to determine a probability distribution of the type of precipitation (PType) and a probability distribution of the rate of precipitation (PRate) over a period. These two probability distributions may then be combined into a plurality of single probability distributions (PTypeRate forecasts) each indicating the probability of occurrence of a certain type of precipitation at a certain rate over a period over the given location.

Abstract: A diffuser for a centrifugal impeller assembly of a gas turbine engine includes a diffuser case having a plurality of vanes extending therein defining a plurality of circumferentially distributed angled passages in communication with an inlet space. Each vane includes a bleed port defined in a suction surface thereof, in proximity of the leading edge. The diffuser case includes a passive fluid communication defined at least partially through each one of the vanes between each bleed port and the inlet space upstream of the leading edge, such that air bled through the bleed ports is recirculated upstream of the leading edges to the inlet space to increase a surge margin of the diffuser.

Abstract: Diffusion in the vane island passages of a centrifugal compressor diffuser is in part controlled by contouring the diffuser passage wall with low profile surface variations. The surface variations can be provided in the form of flow boundary disrupting protrusions disposed within the downstream portion of the vane island passages to prevent flow separation.

Abstract: The automatic utensil wrapping machine is an apparatus for wrapping a napkin around one or more utensils for use as a place setting. The apparatus comprises a housing, a support frame and an assembly of elements mounted to the support frame. The assembly of elements includes a napkin lifting station, a napkin wrapping station, a napkin transfer station, a utensil transfer station, and a napkin folding station. The apparatus wraps each napkin around a predetermined amount of utensils without the need for human contact. The napkins are wrapped by first positioning a stack of napkins on the lifting station, then individually transferring napkins from the lifting station to the wrapping station. The utensils are then transferred from the individual cartridges and placed onto the napkin. Two opposing corners of the napkin are then folded over and the napkin is subsequently wrapped around the utensils.

Abstract: An exciting sound wave generator is positioned within a nacelle of a jet engine at its inlet to generate an exciting sound wave having a primary frequency generally different from a frequency of the primary tone of the noise. The exciting sound wave is used to modulate the primary tone of the noise and, therefore, distribute sound energy of the noise from the primary tone to a broad range of side bands so that the amplitude of the primary tone of the noise is reduced.

Abstract: An apparatus and method is provided for improving efficiency of a transonic gas turbine engine compressor by bleeding off a shockwave-induced boundary layer from the gas flow passage of the compressor using an array of bleed holes having a downstream edge aligned with a foot of an oblique shock wave which originates on the leading edge of an adjacent transonic rotor blade tip.

Abstract: A centrifugal compressor includes an impeller and a diffuser. The impeller has an inner integral hub with vanes thereon, is adapted to rotate within an outer shroud about a central longitudinal axis, and has a defined hub-to-shroud distribution of fluid exit angles. The diffuser, downstream from the impeller, comprises a plurality of circumferentially spaced discrete passages at least partially defining fluid paths through the diffuser, and angled such that adjacent discrete passages intersect each other to form an annular semi-vaneless diffuser inlet space. The discrete passages downstream of the semi-vaneless space each have an inlet therefrom and an outlet with a greater cross-sectional area than the inlet. The intersection of the annular semi-vaneless space and each discrete passage defines a leading edge thereof.
