Comparative Evaluation of Cleaning Capacity and Efficiency of Kedo-S Pediatric Rotary Files, Rotary ProTaper, and Hand K Files in Primary Molar Pulpectomy.

Aim and objectiveTo assess and compare the cleaning efficacy and instrumentation time of K files, ProTaper, and Kedo-S rotary files in primary molars.Materials and methodsIndia ink was injected into 120 root canals of selected primary molars. The root canals were randomly and equally divided into three groups based on instrumentation technique: group I—K files, group II—ProTaper, and group III—Kedo-S. After instrumentation with respective method, the canals were cleared and observed under a stereomicroscope, the instrumentation time for each root canal was also measured with a stopwatch. Statistical analysis was done with one-way analysis of variance (ANOVA) and post hoc Bonferroni.ResultKedo-S rotary files performed significantly better cleaning of the canals in the coronal and middle third than ProTaper and K files (p = 0.0001). In the apical third, the difference between the two rotary systems was not significant. The time taken for instrumentation was lowest with Kedo-S followed by ProTaper and K files.ConclusionKedo-S pediatric rotary system showed significantly better cleaning than ProTaper rotary system and K files in cleaning primary molar root canals.Clinical relevanceThe anatomy and morphology of primary teeth demand a specialized file system that will overcome the shortcomings of conventional biomechanical preparation. Kedo-S files, being exclusive pediatric rotary files, might prove to be a boon in primary canal preparation.How to cite this articleKalita S, Agarwal N, Jabin Z, et al.

Fast and Accurate Video Retrieval of a DVR Special-Purpose File System

Based on the characteristics of video storage, this paper analyzes the shortages of existing file system in video application. Then a DVR (Digital Video Recorder) special-purpose file system is proposed. In this special file system efficient video storage and retrieval can be achieved. Video pictures of specified time can be positioned quickly and accurately.

A Stackable Filesystem for Realtime Network Backup

We propose and implement a new stackable filesystem to backup data on a network in realtime, and discuss the basic performance. Conventional mirroring technologies utilize the mirroring function on the device layer or need a special filesystem, the allocation of the disk and the specific format of the filesystem are needed, and so the filesystem allocation is fixed. Therefore, when a backup operation is required for new services, mirroring in the device layer or the special filesystem cannot be implemented. The proposed stackable filesystem realize the backup functions without changing the device and filesystem allocations by the VFS mechanism. So it enables the realtime network backup. Moreover, it advances the throughput of reading and writing by making the NFS system function invoked from the inside of the filesystem. We developed this filesystem, and evaluated the performance from the viewpoint of throughput, system call speed and CPU loads. The results show that there is no problem in the viewpoint of the performance compared with the conventional filesystem, and the throughput of the read and write of GMFS is 2.0 times faster than conventional mirroring filesystem.

Operating MSDOS in a Controlled Environment

Abstract Due to costs and performance PC architectures running MSDOS systems (IBM, 1986) are widespread. With the software platform available market is still growing. However from the point of view of security and operating systems concepts this architecture is all but outstanding. Most efforts to improve security have side effects on the compatibility. Starting with a secure state influence on security and integrity can only come from outside. Thus, keeping a computer system safe means control of external data and I/O operations. The presented approach for keeping the system safe in a MSDOS environment is performed by introducing an alternate special file system with security and integrity features. It is based upon a reliable boot procedure as a crucial point in system. As experience with alternate file systems for other purposes exist the approach can be qualified as feasible. As a further side effect of the method presented, unattended periods can be controlled to a remarkable extent.

Total Network Data System: Data Acquisition and Near-Real-Time Surveillance by EADAS

The Total Network Data System (TNDS) requires a facility to collect the traffic data generated by electromechanical and electronic offices. The Engineering and Administrative Data Acquisition System (EADAS) fulfills this function. EADAS systems that serve electromechanical offices employ unique self-testing circuitry to interface to central office signals. A novel buffering scheme also improves system efficiency. For electronic offices, a specialized file system has been developed, and the input data are specified in a high-level language. All of these features permit EADAS to be a cost-effective, flexible, and reliable data collection system. EADAS also provides real-time surveillance and reports for the switching offices it serves. A set of reports is predefined; however, the user may also specify reports using the Network Operations Report Generator feature (NORGEN). System capacity is specified in simple formulas which are derived and presented. With these features, EADAS provides a comprehensive facility for presenting real-time traffic data to the telephone companies.
