Abstract

fetched live from OpenAlex

There has been a lot of interest in Smartphone technology over the last few years.Many of these phones are capable of email, internet access, and have a built in camera.Perhaps no Smartphone has generated as much interest as the iPhone.One of the features of the iPhone is that it can be programmed in Objective C using Xcode (the standard programming interface for a MAC).This paper describes an application of an iPhone that faculty and senior design students in the TAC/ABET accredited B.S. Electromechanical Engineering Technology at Miami University are working on.An iPhone application was written in Objective C that allows the user to take a picture of a bar code displayed on a computer screen using the built in iPhone camera.The software processes the image and determines the corresponding code39 characters.Students are currently working on transmitting the barcode data to a remote data terminal.This system would have many uses for applications that require remote data acquisition, time/date stamping, and lab work verification.An example would be collecting inventory information from products that are separated by large distances from a data collection device.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
