Abstract: Techniques are described that detect areas with insufficient radio frequency (RF) coverage in a wireless network. A network management system (NMS) determines one or more service level expectation (SLE) metrics for each client device in a wireless network. The SLE metrics are aggregated to each access point (AP) in the wireless network, and each AP is assigned an AP score based on the aggregated SLE metrics. To identify potential coverage holes, the NMS groups APs having poor AP scores. If a root cause of the poor AP scores cannot be automatically resolved and if the poor AP scores persist for a predetermined period of time, the group of APs is determined to represent a true coverage hole. The NMS may generate a notification regarding recommended corrective actions to the customer and/or IT personnel.

After the vibration source increases the bulk density of the fill material, the fill material ratio can range from about 0.15 to about 0.75.

Abstract: Disclosed are methods and systems for automatic generation and distribution of curbside map data. A server receives municipal regulation data from an external source, and processes the municipal regulation data to generate curbside map data. The server also transmits a message conveying at least a portion (e.g. relevant portion based on request) of the curbside map data to a client computing device. By obtaining and processing the municipal regulation data, the curbside map data can be generated and distributed without time consuming and error prone disadvantages of manual surveying.

Abstract: The invention advances the ratio method of phosphor thermography using two machine vision cameras for full-field temperature measurements of a solid surface. As an example, algorithms from digital image correlation (DIC) can be used to determine the stereoscopic imaging system intrinsic and extrinsic parameters, and accurately register material points on the sample to subpixel locations in each image with 0.07 px or better accuracy. A phosphor calibration sample fabricated using aerosol deposition can be used for in situ determination of the temperature-versus-intensity ratio relationship. The full calibration methodology and several improvements on two-color phosphor thermography open the door for full-field temperature measurements in dynamic tests with deforming test specimens.
