Analysis of air-void system in hardened concrete from a three-dimensional perspective
… the measurement of air voids by using a flatbed scanner for image acquisition, applying new methods for segmenting the image, and using new ideas for the analysis of the image data. The cement paste is protected when an air bubble is close enough in proximity to relieve the stress created …

Buckling and friction-based linear motion clutch with application to medical devices
… method to measure the tube geometry using a flatbed scanner was developed and studied. This method was found to provide excellent accuracy and repeatability for measuring tubes, and has shown potential as a measurement method for many other applications.

Finite element modeling of high frequency irreversible electroporation
… pulse number (25 – 75). Following experiments, a flatbed scanner was used to acquire images of the visibly discolored tissue, which has been previously shown to be indicative of the ablation pattern. The experimentally observed ablation zones were then compared to model-predictions by using image …

Black-box printer models and their applications
… (Epson America, Inc., Long Beach, CA, USA) flatbed scanner operated at 2400 dpi under different analysis resolutions. The experiment results show that the larger neighborhood models yield a significant improvement in the accuracy of the prediction of the pixel values of the printed halftone …

The Relative Contribution of Hudson River Tributaries to River Herring Spawning Dynamics
… ovary egg contents using an Epson Perfection V19 flatbed scanner and ImageJ software allowed for fecundity analysis. Standardized river herring standing egg crop (mean egg count per female) was multiplied by female river herring population estimates, obtained from Delta Vision HD underwater camera …

Advances in measuring parameters of the air-void system in hardened concrete
… are used to characterize the air void system. A flatbed scanner is used to acquire a single high resolution image of the polished surface of a concrete sample. The concrete surface is polished and treated with phenolphthalein and orange powder to facilitate segmentation of air bubbles, paste and …

Microstructure characterization of foamed cement and concrete
… ASTM C457 were also estimated using an automated flatbed scanner method. There was no significant change in the spacing factors of the concrete mixtures subjected to vibration, indicating the robustness of the air-void system. The results also showed strong correlation on the air content and …

Colorimetric sensor array for identification of fungi & ultrasonic spray synthesis for supercapacitor materials
… (~$3 for each test kit using an ordinary flatbed scanner) allows for real-time identification of fungi in culture. We expect this is the first step in the development of a rapid, facile, and low-cost tool for diagnosis of fungal infections with potential additional applications for …
