Abstract

fetched live from OpenAlex

The artificial pancreas is composed of a continuous glucose sensor that senses the user's sugar level, an insulin infusion pump that secretes insulin into the user's body when required; and an algorithm that regulates the insulin based on the glucose levels obtained from the sensor. In order to minimize cost and time to build and verify such a complex system, one must first model and simulate the system. This methodology in turn provides risk-free testing environments and can also be tested with different scenarios. This thesis will focus on modelling and simulating the artificial pancreas using Discrete EVent System Specification in Real-Time (DEVSRT).This is accomplished by simulating both a meal model and a control algorithm to control the insulin pump based of the data provided by the continuous glucose monitor. The meal model simulation will validate the control algorithm model.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
