Abstract: In a method of multi-modal multi-task environmental quality forecasting, multi-modal data associated with a plurality of environmental input features is received. A neural sub-network of a plurality of neural sub-networks is applied to each modality of the multi-mode data associated with each environmental input feature of the plurality of environmental input features. A neural network is applied to outputs of each of the plurality of neural sub-networks, wherein the neural network includes a trained model for forecasting the plurality of environmental qualities. An environmental quality forecast is output for the plurality of environmental qualities.

Abstract: Disclosed are methods, systems and non-transitory computer readable memory for systems engineering. For instance, a method may include: receiving, via an input graphical user interface or one or more data connectors, engineering information, wherein the engineering information includes data for a plurality of entities stored on a datastore; processing, using a language model, the engineering information to output entity information, wherein the entity information includes one or more data attributes of a first entity of the plurality of entities; querying an ontological framework using the entity information, wherein querying the ontological framework determines a relationship between the first entity and a second entity of the plurality of entities; and generating an output based, at least in part, on the relationship between the first entity and the second entity.

Abstract: In a computer-implemented method for transformation of inconsistent environmental data, environmental data is received from a plurality of data sources, wherein each data source of the plurality of data sources is associated with a geographic region and maintains the environmental data using at least one data format of a plurality of disparate data formats, such that the environmental data is received in the plurality of disparate data formats. The environmental data is transformed from the plurality of disparate data formats into a consistent data format, such that the transformed environmental data is in a standardized format capable of direct comparison and analysis. The transformed environmental data is stored in a database configured to receive and perform searches on the transformed environmental data.

Abstract: In a computer-implemented method for evaluating air quality, air quality information is received for a plurality of locations for a plurality of days over a time period. For each location of the plurality of locations a severe air quality percentile for the air quality information for each location of the plurality of locations for the time period is determined and a variance of the air quality information for each location of the plurality of locations for the time period is determined. The plurality of locations is evaluated according to the severe air quality percentile for the air quality information and the variance of the air quality information for each location.

Abstract: An improved roof ridge cover. The roof ridge cover is formed to give the visual appearance of multiple shingles. The edges of the roof ridge cover wrap around existing roof shingles. The cover is stone coated to provide similar appearance to the adjacent roof shingle surfaces. Optional venting material may be used under the cover to allow air to vent from the attic thereby allowing the attic to breathe, although the vent material is sufficiently dense to prevent insects and bugs from passing through the vent material.

Abstract: Illumination can be evaluated for patient using a system including a housing, an adjustable light source mechanically coupled to the housing and configured to illuminate an object for viewing by the patient on an axis substantially perpendicular to a surface of the object. A user-adjustable input coupled to the adjustable light source is to obtain information from a user indicative of a calibrated illuminance and a color property to be provided by the adjustable light source including providing a range of adjustable illuminance and color properties selectable by the user. The adjustable light source can be configured to provide light having an illuminance in excess of 300 lux, and the housing can be configured to provide a first specified distance between the adjustable light source and the object for viewing and to obstruct viewing of the light source directly by the patient.

Abstract: Described herein are hands-free vision aids that may be used for low-vision reading. These vision aids may be beneficial for individuals with low-vision disorders such as age-related macular degeneration, retinitis pigmentosa, and other visual disorders. The vision aids described here comprise an optical system with one or more light sources configured to provide a rectangular field of illumination with high illuminance levels bounded by high contrast perimeter. Such an illumination field greatly illuminates a targeted viewing region while reducing glare that arises from illuminating peripheral regions. Some vision aids use green light with high illuminance values for improving visual acuity and comfort for long-duration reading. The optical system of a vision aid may be configured to fit onto and/or integrate with eyeglass frames.

Abstract: A stack, having improved efficiency, for venting exhaust gases from a combustion chamber of a solid fuel burning apparatus, such as a boiler, to a flue. The stack, which can be retrofitted to certain wood burning furnaces or boilers includes an elongated tubular member having a first end, a second end and at least one inlet proximate the first end. The second end of the elongated tubular member defines an outlet which is adapted to register with a flue so as to vent combustion, or exhaust, gases from the combustion chamber to the atmosphere. Further, the stack includes at least one conduit member which is in fluid communication with the first tubular member. The conduit member includes an open end adapted to be in fluid communication with the combustion chamber and an oppositely disposed closed end which is proximate the inlet of the elongated tubular member and is in fluid communication with the inlet of the elongated member.

Abstract: A microfocus type X-ray system in which the electron beam current is generally operated in a milliampere range at a constant power, and the beam is subjected to electronic focusing for selected beam width and steering for directional control.
