In Situ Surface Defect Detection in Polymer Tube Extrusion: AI-Based Real-Time Monitoring Approach.

While striving to optimize overall efficiency, smart manufacturing systems face various problems presented by the aging workforce in modern society. The proportion of aging workers is rapidly increasing worldwide, and visual perception, which plays a key role in quality control, is significantly susceptible to the impact of aging. Thus it is necessary to understand these changes and implement state-of-the-art technologies as solutions.

Tool-Wear-Estimation System in Milling Using Multi-View CNN Based on Reflected Infrared Images.

A novel method for tool wear estimation in milling using infrared (IR) laser vision and a deep-learning algorithm is proposed and demonstrated. The measurement device employs an IR line laser to irradiate the tool focal point at angles of -7.5°, 0.

Prediction of Drill Bit Breakage Using an Infrared Sensor.

In this paper, a novel drill bit breakage prediction method featuring a low-cost commercial infrared sensor to monitor drill bit corner wear is proposed. In the proposed method, the drill bit outer corner wear state can be monitored by measuring reflected infrared light because the reflection phenomenon is influenced by wear, edge shape, and surface roughness of the drill bit. In the experiments, a titanium workpiece was drilled without using cutting fluid to accelerate drill bit fracture.

A technique for a nano-textured gapless microlens array using self-formation characteristics of anodic alumina.

This paper presents a method to utilize the growth properties of anodic alumina possessing self-formation characteristics to fabricate a nano-textured microstructure and also introduces an application technique of the proposed method. The growth rate of anodic alumina, fabricated on aluminum surfaces, has a strong dependence on the intensity of the applied current density or electric field. The uniformity of the thickness of anodic alumina is determined by its electrical distribution characteristics.

Secure reconstruction technique after partial nephrectomy irrespective of tumor size and location.

Introduction: Nephron-sparing surgery for large renal masses is not considered a safe procedure because of high complication rate. We present our experience using expanded polytetrafluoroethylene (Gore-Tex) and Hem-O-Lok (Weck Clip) as hemostatic agents during open partial nephrectomy (OPN) to perform nephron-sparing surgery for large renal masses.

Materials And Methods: Sixty patients underwent OPN for suspicious renal cell carcinomas.

Simple use of the suppository type povidone-iodine can prevent infectious complications in transrectal ultrasound-guided prostate biopsy.

Purpose. To determine the effect of simple use of suppository povidone-iodine on infectious complications after transrectal ultrasonography-guided biopsy of the prostate. Methods.

Evaluation of short term clinical effects and presumptive mechanism of botulinum toxin type A as a treatment modality of benign prostatic hyperplasia.

The purpose of this study was to evaluate the effect and investigate the putative mechanism of botulinum toxin type A (BTA) applied to the treatment of benign prostatic hyperplasia (BPH). A total of 52 patients with symptomatic BPH were evaluated. Transperineal intraprostatic injection under transrectal ultrasonography was carried out.
