Efficient pulmonary nodules classification using radiomics and different artificial intelligence strategies.

Objectives: This study aimed to explore and develop artificial intelligence approaches for efficient classification of pulmonary nodules based on CT scans.

Materials And Methods: A number of 1007 nodules were obtained from 551 patients of LIDC-IDRI dataset. All nodules were cropped into 64 × 64 PNG images , and preprocessing was carried out to clean the image from surrounding non-nodular structure.

Performance of Different Concrete Types Exposed to Elevated Temperatures: A Review.

Concrete is a heterogeneous material that consists of cement, aggregates, and water as basic constituents. Several cementitious materials and additives are added with different volumetric ratios to improve the strength and durability requirements of concrete. Consequently, performance of concrete when exposed to elevated temperature is greatly affected by the concrete type.

Evaluation of Workability and Structuration Rate of Locally Developed 3D Printing Concrete Using Conventional Methods.

Concrete 3D printing is a novel construction method that can bring new horizons to the construction industry. However, there are still many challenges that limit its capabilities. Despite the huge research efforts, to date, there are still no standardized acceptance criteria and guidelines for the evaluation of printing concrete.

A device to facilitate separation of components of combined screw- and cement-retained implant-supported crowns.

This article describes a technique to separate parts of cemented implant-supported restorations with a screw hole. A device was designed by using a computer-aided design (CAD) program and was milled in a milling center. The restoration was heated to 400 °C and then subjected to controlled mechanical force with the help of the device to separate the cemented parts.

Shear Strength of Fiber Reinforced Recycled Aggregate Concrete.

In this paper, shear strength of fiber reinforced recycled concrete was investigated. A Self Consolidated Concrete (SCC) matrix with 100% coarse recycled aggregate and different types of fibers were used in the study. Steel (3D and 5D), synthetic and hybrid fibers with a volume fraction of 0.
