Abstract: Methods and systems for searching logical patterns in voluminous multi sensor data from the industrial internet is provided. The method retrieves instances of patterns in time-series data where patterns are specified logically, using a sequence of symbols. The logical symbols used are a subset of the qualitative abstractions specifically, the concepts of steady, increasing, decreasing. Patterns can include symbol-sequences for multiple sensors, approximate duration as well as slope values for each symbol. To facilitate efficient querying, each sensor time-series is pre-processed into a sequence of logical symbols. Each position in the resulting compressed sequence is registered across a TRIE-based index structure corresponding to the multiple logical patterns it may belong to. Logical multi-sensor patterns are efficiently retrieved and ranked using such a structure. This method of indexing and searching provides an efficient mechanism for exploratory analysis of voluminous multi-sensor data.

Abstract: Some sensitive metal surfaces are often unable to be contacted effectively with hydrofluoric acid or acidic fluoride ions due to significant corrosion issues that may occur. Metal surfaces comprising titanium or a titanium alloy represent but one example of sensitive metal surfaces having this issue. Corrosion inhibitor compositions comprising boric acid and other boron-containing compounds may at least partially suppress corrosion of titanium and titanium alloy surfaces. Methods for suppressing corrosion may comprise: contacting a metal surface comprising titanium or a titanium alloy with a corrosion inhibitor composition comprising a boron-containing compound; and interacting the metal surface with a fluid phase comprising hydrofluoric acid or acidic fluoride ions.

The sensor ceases transmission of the signal when the wear on the portion of the downhole cutting tool reaches the first amount.

The method may further include scanning the at least one calibration disk and the pellet using the CT scanner to obtain one or more CT images of the pellet and the at least one calibration disk, and comparing a density of the pellet with the known density of the at least one calibration disk based on the one or more CT images.

Abstract: Methods and systems for Assurance-enabled Linde Buzo Gray (ALBG) data clustering is described herein. In an implementation, a user model data from a database available to the processor is obtained. The user model data comprises data elements or users, each of which corresponds to features and feature values associated with the users. These data elements of the user model data are segmented into clusters using our segmentation approach with an initial accuracy criterion parametric value and the output is captured as segment data. The segment data output is checked for initial pareto validity. If successful, iterative segmentation run with incremental accuracy criterion using parameterized value is performed till the segmented clusters are determined valid against pareto validity check. The last successful pareto valid segmented cluster data is considered as the finalized segment output data.

Abstract: A method for fabricating a metal-matrix composite tool includes positioning an inner mold within an outer mold and thereby defining a gap between the inner and outer molds. A first reinforcement material is then loaded into the gap, and the first reinforcement material is infiltrated at a first temperature with a first binder material and thereby forming an outer shell. The inner mold is then removed and a second reinforcement material is loaded at least partially into the outer shell and infiltrated at a second temperature with a second binder material and thereby forming a reinforced composite material. The second temperature is lower than the first temperature and the second binder material is different than the first binder material. The outer shell is attached to exterior portions of the reinforced composite material.

Abstract: The system and method for recognizing and counting products within images is disclosed. The products are recognized by carrying out a nearest-neighbor search in the template feature space using a k-d tree and the product count is then obtained by using a maximum feature repeatability index for each identified feature. The system also obtains product arrangement by fitting bounding boxes around each identified product. The count of boxes thus obtained may also provide the exact number of discrete products visible in an image. A second stage of grid-based search is also carried out in the neighborhood of each detected product to detect new products that might have been missed out in the previous step. This detection is based on a confidence measure including information like histogram matching and spatial location of products. This system is also useful in verifying planogram compliance for a given product.
