Abstract: An embodiment for analyzing and tracking data flow to determine proper schemas for unstructured data. The embodiment may automatically use a sidecar to collect schema discovery rules during conversion of raw data to unstructured data. The embodiment may automatically generate multiple schemas for different tenants using the collected schema discovery rules. The embodiment may automatically use ETL to export unstructured data to SQL databases with the generated multiple schemas for the different tenants. The embodiment may automatically monitor usage data of the SQL databases and collect the usage data. The embodiment may automatically optimize schema discovery using the collected usage data. The embodiment may automatically discover schemas with hot usage and apply the discovered schemas with hot usage to other tenants for consumption and further monitoring.

Abstract: A method, computer system, and a computer program product is provided for computer log management. In one embodiment, in response to receiving a log request from a user, an input content is analyzed and adjusted according to input contents and user's previous activities. A similarity analysis and a fairness analysis is performed to determine similarities between the input content, as adjusted, and a plurality of log records in an object library. The similarity analysis includes analyzing any patterns and attributes. The attributes have a dimension, and each dimension has a predefined weight (W). The fairness analysis ensures that one type of log is not favored over others. A best possible match is then determined, and one or more logs are presented to the user providing the best possible match.

Abstract: One or more computer processors generate a debug chain from one or more similar resource bound breakpoints, wherein the debug chain provides dynamic code flow. The one or more computer processors distribute the generated debug chain to one or more tenants.

Abstract: A disclosed database system and enhanced methods implement enhanced mini-plans and dynamically changing a query mini-plan with trustworthy Artificial Intelligence (AI) to improve query execution performance in a database system. An AI cost model evaluates candidate mini-plans for executing a query. AI truth monitors evaluate the execution of the mini-plans, such as predicted input factors and adjusted mini-plans of one or more AI running data models. The AI truth monitors provide feedback to adjust the AI cost model based on evaluating the execution of the mini-plans. The AI truth monitors validate adjusted mini-plans, provide feedback to the AI cost model with improved overall prediction accuracy, and enhanced mini-plans to gain query performance.

Abstract: An embodiment includes generating a partition schema for a distributed database based on historical usage data indicative of usage of the distributed database, where the generating of the partition schema comprises determining a partition range of a partition of the partition schema. The embodiment also includes generating a node identifier for the partition using a hash function and a first weight value assigned to the partition. The embodiment also includes monitoring performance data indicative of a performance of the distributed database, the monitoring comprising detecting a failure of the performance to satisfy a performance threshold. The embodiment also includes initiating, responsive to detecting the failure, a redistribution procedure by changing the node identifier of the partition by replacing the first weight value with a second weight value.

Abstract: Suggested is a composite particle comprising or consisting of a solid core partially or entirely coated with at least one inorganic compound, wherein (a) said solid core is a carbon black particle carrying functional groups on its surface, and (b) said at least one inorganic compound shows a particle size of from about 5 to about 100 nm, wherein said solid core particles show a diameter of primary particle size from about 5 to about 500 nm.

Abstract: The system and method may determine a subset of electronic account holders where the subset previously used an electronic account to make a purchase in predetermined categories. The purchase habits of the subset may be analyzed by reviewing the past purchase of the subset during a time period, determining reduced members of the subset wherein reduced members comprise members which reduce usage of the electronic payment account during the time period and determining parameters of the reduced members. A flight risk may be determined for the electronic payment users by analyzing the subset for members that comprise the parameters, determining a flight risk score by scoring the parameters and identifying flight risk members wherein flight risk members include members scored over a threshold. In response, an electronic offer may be communicated to the flight risk members.

Abstract: The MoSi2 heating element has not been so resistant under the low-temperature heating, because the low-temperature oxidation, which is attributable to the grain boundary oxidation, occurred. In the present invention, long life under the low-temperature heating is attained by the following two structures. (1) The MoSi2 grains have a network structure and are linked three dimensionally. (2) The secondary, silica-bearing oxide or glass phase forms a net-like structure around the MoSi2 grains.

Abstract: In an infrared radiation source containing hot-pressed molybdenum disilicide reinforced with silicon carbide whiskers as the illuminant thereof, terminal portions of the illuminant having a protective dense silica film of 5 to 20 .mu.m in thickness formed on the surface thereof which portions are to be heated at a temperature of 400 to 800.degree. C. are either set to have a current density of at most 12 A/mm.sup.2 or disposed in dry air having a relative humidity at 25.degree. C. of at most 30% (absolute humidity: 0.00588). As a result, the low-temperature oxidation phenomenon that would otherwise be developed in the terminal portions of the illuminant is suppressed. Thus, there can be obtained an infrared radiation source containing an illuminant made of molybdenum disilicide reinforced with silicon carbide whiskers and having a long serviceable life span.

Abstract: A ceramic heating element includes a heat-generating portion 1 formed of a ceramic composite material with 3 to 40 vol. % of silicon carbide (SiC) whiskers and the balance substantially of molybdenum disilicide (MoSi.sub.2), and electrode portions 2a and 2b provided on both ends of the heat-generating portion 1.
