The rapid progress of modern computing systems has led to a growing interest in informative run-time logs. Various log-based anomaly detection techniques have been proposed to ensure software reliability. However, their implementation in the industry has been limited due to the lack of high-quality public log resources as training datasets. While some log datasets are available for anomaly detection, they suffer from limitations in (1) comprehensiveness of log events;(2) scalability over diverse systems;and (3) flexibility of log utility. To address these limitations, we propose AUTOLOG, the first automated log generation methodology for anomaly detection. AUTOLOG uses program analysis to generate runtime log sequences without actually running the system. AU-TOLOG starts with probing comprehensive logging statements associated with the call graphs of an application. Then, it constructs execution graphs for each method after pruning the call graphs to find log-related execution paths in a scalable manner. Finally, AUTOLOG propagates the anomaly label to each acquired execution path based on human knowledge. It generates flexible log sequences by walking along the log execution paths with controllable parameters. Experiments on 50 popular Java projects show that AUTOLOG acquires significantly more (9x-58x) log events than existing log datasets from the same system, and generates log messages much faster (15x) with a single machine than existing passive data collection approaches. AUTOLOG also provides hyper-parameters to adjust the data size, anomaly rate, and component indicator for simulating different real-world scenarios. We further demonstrate AUTOLOG's practicality by showing that AUTOLOG enables log-based anomaly detectors to achieve better performance (1.93%) compared to existing log datasets. We hope AUTOLOG can facilitate the benchmarking and adoption of automated log analysis techniques.

Students in compiler principle course often encounter difficulties in understanding abstract programming concepts and need first-aid assistants in the context of independent learning. An innovative Large Language Model-based assistant ComPAT (Compiler Principles course AssisTant) is proposed in this paper. ComPAT uses vector database for text segmentation and similarity queries, meta prompting for answer refinement and challenging questions for heuristic learning. A compiler principles domain-specific dataset with 1520 questions is constructed. Compared to ChatGPT3.5, ERNIE3.5, and ChatGLM4, ComPAT has shown superior performance in handling fill-in-the-blank and question-and-answer. ComPAT demonstrates an innovative and promising use of LLM-based teaching/learning assistant system in computer education.

The complexity of innovative products is increasing due to implementation of emerging technologies and rise in system complexity because of greater system and software functionality and inter connectivity, to address the challenge, multiple engineering disciplines must be well-coordinated in product lifecycle management tools. Complexity of novel products have also demanded the establishment of life cycle spanning development from the conceptualization till product realization. The application of MBSE inside PLM tools to keep requirements-in-loop becomes paramount for timely decision support. Unfortunately, keeping a requirements traceability within product development is still a challenge. In aerospace domain, due to innate complexity results in huge number of mission critical requirements which need to be verified and validated to make well informed design decisions throughout the product development process. In this paper, we have proposed a method to implement MBSE using RFLP approach in PLM tool using a Cubesat case study, to keep requirements-in-loop during initial phase of product development.
