#3938 Software Hazard Report PDF Parser #3938  Provide a python application to parse a NASA software hazard report in PDF format, generating a CSV with: hazard report title, cause, control, verification, where each report has several causes, several controls per cause, and one or more verifications per control This is a classic data extraction problem involving hierarchical data (1 Report --> Many Causes --> Many Controls --> Many Verifications) embedded in a flat PDF format. Because NASA hazard reports vary (e.g., specific formats like text-heavy documents vs. tabular forms like NF 1707), the most robust approach is a State Machine Parser . This script reads the PDF line-by-line, detects keywords (like "Cause:", "Control:"), and maintains context to flatten the hierarchy into a CSV. Prerequisites You will need the pdfplumber library, which is superior to PyPDF2 for maintaining text layout and extracting data from forms. pip install pdfplumber pandas ...

#3937 Learning Progression in 0-10 Year Olds

#3937 Learning Progression in 0-10 Year Olds #3937  Describe in layman's terms the progression of learning for a child 0-10 Thinking of a child's learning journey as a ladder or a straight line is tempting, but in reality, it's more like a spiral . Children revisit the same skills—like communication or problem-solving—but at deeper and more complex levels as they grow. Here is the progression of learning from birth to age 10, broken down into simple terms. Phase 1: The Sensory Explorer (0–18 Months) The Main Goal: Figuring out "How does this body work?" and "Can I trust the world?" How They Learn: Through their five senses. They don't "think" in words yet; they think in actions. Key Milestones: Cause and Effect: Around 6–9 months, they realize, "If I drop this spoon, it makes a loud noise (and Mom picks it up)." This is their first physics lesson. Object Permanence: They learn that things (and people) still exist even when the...
