A real–time surface interpolator is developed, to machine a family of swept surfaces directly from their high–level procedural definitions. All the computations required for machining are performed in real time based on the exact surface geometry, including tool path planning, tool path interpolation, tool offsetting, and tool path step–over to achieve a prescribed scallop height. A G–code comm...

Shift is a lightweight framework for high performance local and remote file transfers that provides resiliency across a wide variety of failure scenarios. Shift supports multiple file transport protocols with automatic selection of the most appropriate mechanism between each pair of participating hosts allowing it to adapt to heterogeneous clients with differing software and network access rest...

Lightweight databases and key-value stores manage the consistency and reliability of their own data, often through rollback-recovery journaling or write-ahead logging. They further rely on file system journaling to protect the file system structure and metadata. Such journaling of journal appears to violate the classic end-to-end argument for optimal database design. In practice, we observe a s...

The doubly-chained tree is a data structure for organizing files in a database system. We model such systems with a trie, a tree in which leaves correspond to records from a file. Retrieval proceeds by following a path in a trie from the root to a leaf, where the edge taken at each node is determined by some attribute value of the query. For a given file, altering the order in which attributes ...

prepared when shaping files have a reproducible and sufficiently-sized pathway to follow. The secret to shaping success is glide path management (GPM), which may be thought of as procedures directed toward "securing" canals. Any portion of any canal is termed secured when a small-sized flexible hand file can reproducibly slip, slide, and glide through a catheterized canal.1 Similar to a cardiac...

The file transfer committee met and discussed the Mail Box Protocol RFC 221, NIC 7612. The potential utility for the mechanism was confirmed and a couple of changes suggested. We first give the changes and then restate the Protocol. CHANGES 1) The Mail Box Protocol is only to allow ASCII stings of text formatted for a network standard line printer rather than allowing other data types. 2) A new...

A problem conamonly faced by users of the World-Wide Web (WWW) is forgetting the path traversed to reach a previously read document. SWISS (Seeking WorldWide Web Information Using a Signature File Search) is a system designed to alleviate this ’lost document problem’ by incrementally saving the contents of visited documents in a signature file index. SWISS allows the user to retrieve a previous...

# Display the current working directory getwd(); # If necessary, change the path below to the directory where the data files are stored. # "." means current directory. On Windows use a forward slash / instead of the usual \. workingDir = "."; setwd(workingDir); # Load the WGCNA package library(WGCNA) # The following setting is important, do not omit. options(stringsAsFactors = FALSE); # Load th...

Background and Aim: Maintaining the original central canal path during cleaning and shaping of the root canal system plays an important role in the success of endodontic treatment. This study sought to compare canal transportation and centering ability of WaveOne and SafeSider rotary files using cone-beam computed tomography (CBCT). Materials and Methods: This in-vitro, experimental study was ...

Abstract Background This randomized clinical trial aimed to compare the preparation time and severity of postoperative pain between HyFlex Electric Discharge Machine (EDM) glide path file (GPF) PathFile. Methods Eighty patients whose molar teeth had at least one severely curved canal were treated by same specialist. After access cavity preparation, randomly assigned receive enlargement with eit...
