چکیده

We present the most interesting elements of the correctness specification of BilbyFs, a performant Linux flash file system. The BilbyFs specification supports asynchronous writes, a feature that has been overlooked by several file system verification projects, and has been used to verify the correctness of BilbyFs’s fsync() C implementation. It makes use of nondeterminism to be concise and is shallowly-embedded in higher-order logic.

Ex Vivo Comparison of File Fracture and File Deformation in Canals with Moderate Curvature: Neolix Rotary System versus Manual K-files

Background and Aim: Cleaning and shaping is one of the important steps in endodontic treatment, which has an important role in root canal treatment outcome. This study evaluated the rate of file fracture and file deformation in Neolix rotary system and K-files in shaping of the mesiobuccal canal of maxillary first molars with moderate curvature.    Materials and Methods: In this ex vivo exp...

Accuracy of an Intraoral Digital System for File Length Measurement

Introdouction: Canal length measurement is essential for proper endodontic treatment. Any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. Digital radiography has enabled accurate measurement of curved canal length. In this study, we evaluated the accuracy of calibration of a complementary m...

Generating Realistic Datasets for Deduplication Analysis

Deduplication is a popular component of modern storage systems, with a wide variety of approaches. Unlike traditional storage systems, deduplication performance depends on data content as well as access patterns and meta-data characteristics. Most datasets that have been used to evaluate deduplication systems are either unrepresentative, or unavailable due to privacy issues, preventing easy com...
