Abstract: A system and method for collaborative smart evidence gathering and investigation for incident response attack surface management and forensics in a computing environment is disclosed. The system obtains evidence data from multiple sources with various entry points, capturing contextual information. Further, the system processes the data using an artificial intelligence (AI) root cause analysis, graph augmented retrieval, semantic classifier, meaning extraction, and causal discovery model. Furthermore, the system performs similarity analysis to assess evidence quality, sufficiency, and completeness. Based on the evaluation, the system determines appropriate actions to be taken on the processed evidence data. Additionally, the system executes the actions to resolve the incidents effectively by using a smart expert system, a human agent participation, or an AI co-pilot, as a first-class investigator and collaborator in the process.

Abstract: A computer-implemented system and method for generating time-based contextual graph in cloud computing environment is disclosed. The system receives, from computing devices, requests corresponding to security anomaly analysis of cloud infrastructure-based resources and applications. The system identifies parent node and node attributes corresponding to parent node in cloud infrastructure-based resources and/or applications, based on requests. Further, system determines hierarchical node relationships between parent node and child nodes, based on identified node attributes. Furthermore, system analyses risks in context of security anomaly associated with cloud infrastructure-based resources and/or applications, based on hierarchical node relationships between parent node and child nodes. Further, system generates time-based contextual graph corresponding to analyzed risks in context of security anomaly, based on determined hierarchical node relationships.

Abstract: The disclosure relates to method and system for providing a MIMO transceiver in high speed mobility. The method includes dividing, by the wireless MIMO transmitter, transmission data into a plurality of transmit chains corresponding to an antenna. The method further includes generating for the plurality of transmit chains, a Circularly Pulse Shaped Orthogonal Time Frequency Space (CPS-OTFS) time frequency signal based on a first primary parameter. Value of the first primary parameter is determined based on a first predefined algorithm. The method further includes converting for the plurality of transmit chains, the CPS-OTFS time frequency signal to a CPS-OTFS time domain signal based on at least one of a plurality of secondary parameters. A first plurality of N-point Inverse Fast Fourier Transform (IFFT) are employed on the CPS-OTFS time frequency signal. The first plurality corresponds to the number of sub-carriers and N corresponds to a set of time symbols.

Abstract: Methods for determining a recovery state of a metal alloy are disclosed herein. In one example, a fluctuation in a crystallographic grain orientation of the metal alloy is determined by utilizing electron backscatter diffraction (EBSD) data of the metal alloy. A processor of an electron backscatter diffraction machine utilizes a local orientation deviation quantifier to correlate the fluctuation in the crystallographic grain orientation of the metal alloy with a plastic strain recovery of the metal alloy. Other examples of the method are also disclosed herein.

Abstract: A method of enhancing the ductility of magnesium alloy sheets containing 85% or more by weight of magnesium is described. An annealed, substantially strain free, sheet of generally uniform grain size is locally deformed in local regions to develop strained ‘islands’ of a predetermined strain embedded in a substantially strain-free matrix and then annealed. The deformed regions undergo recrystallization and grain growth while the remainder of the sheet suffers only minor change in grain size, leading to sheet with grains having a bimodal size distribution. The ductility of alloys processed in this way is significantly greater than the ductility of the unprocessed, uniform grain size alloy without compromise to the tensile strength of the alloy.

Thereafter, a perfective effort is determined based on the perfective factors, the predefined rules, and the corrective effort. Subsequently, an adaptive effort is determined based on the adaptive factors, the predefined rules, the corrective effort, the preventive effort, and the perfective effort.
