Sistem multi-agent cu neuron fracționar pentru optimizarea toleranțelor dimensionale. Python, Streamlit
Google Sheets / Apps Script tool for mechanical tolerance stack-up analysis using Worst Case, RSS and statistical methods.
Toltech : 3D tolerance analysis application for complex mechanical assemblies using kinematic and isostatic modeling.
Tolerance Stack-Up Analysis Tool
Henrik Thorwaldsson – Mechanical Design Engineer focused on mechanical design, tolerance analysis and engineering automation.
Aircraft engine bracket · structural FEA · topology optimisation (~22% mass reduction) · GD&T (ASME Y14.5-2018) · tolerance stack-up · Teamcenter PLM
Fits and tolerance calculators for mechanical design. ISO 286 fits, tolerance stack-ups, MMC bonus tolerance, and process capability, with plain-language results.
Tolerance analysis pipeline for a precision optical sensor fixture, using worst-case/RSS analysis, seeded Monte Carlo simulation, sensitivity analysis, Cp/Cpk capability, DOE, and intervention studies.
Exact offline allocation of finite shim stock with worst-case tolerance proof
Open-source analog-AI circuit research twin with differential conductance encoding, managed ngspice, tolerance analysis, and reproducible evidence.
Simple Monte-Carlo library for tolerance analysis in engineering applications
Using the Python programming language, this analysis tested seven hypotheses across three phases: whether AI, BCT, and BDA relate to, individually predict, and jointly predict the perceived effectiveness of Forensic Fraud Investigation (FFI). Pearson correlation, simple and multiple linear regressions were used, with OLS assumption checks reported.
Tolerance stack-up and process capability analysis with worst-case, RSS and Monte Carlo simulation.
Desktop app for 1D mechanical tolerance stack-up analysis
Claude skill that checks whether parts will still fit when each is made slightly off-size: worst case, RSS, mean-shift, and Monte Carlo tolerance stack-ups.
