We demonstrate XClean, a data cleaning system specifically geared towards cleaning XML data. XClean’s approach is based on a set of cleaning operators. Users may specify cleaning programs by combining operators using the declarative XClean/PL language, which is then compiled into XQuery. We plan to show XClean in action on several scenarios based on real-world data. A graphical user interface s...

The Major Atmospheric Gamma(γ)-ray Imaging Cherenkov (MAGIC) telescope is currently the largest single-dish Imaging Atmospheric Cherenkov Telescope (IACT) in operation. The telescope is located on the Canary Island of La Palma at El Roque de los Muchachos observatory. MAGIC aim is to perform γ-ray astronomy in the energy range from 30 GeV to 30 TeV in the so-called very high energy (VHE) regime...

Analysts often clean dirty data iteratively–cleaning some data, executing the analysis, and then cleaning more data based on the results. We explore the iterative cleaning process in the context of statistical model training, which is an increasingly popular form of data analytics. We propose ActiveClean, which allows for progressive and iterative cleaning in statistical modeling problems while...

The complete coverage path planning algorithm based on A* algorithms for the cleaning robot in known environment is proposed in this paper, which uses A* algorithm as heuristic in the U-turn search algorithm. The idea of this algorithm is the cleaning robot clean the cleaning area from the point of origin by using U-turn algorithm, then planning of the shortest path from cleaning robot to not c...

A study was undertaken to evaluate different procedures to safely remove microorganisms, protein, and mammalian cells from materials and provide a suitable method for cleaning and assessing effectiveness of cleaning medical devices for reuse or for analysis of failure. Safety considerations for the personnel performing the cleaning or handling the device after cleaning are important issues. Pol...

BACKGROUND The cleaning of endodontic and all dental instruments prior to sterilization is a prerequisite for their processing for re-use. This study aimed to develop a clinically practical cleaning protocol for rotary nickel-titanium (NiTi) endodontic files prior to sterilization. METHODS Cleaning experiments were conducted on six different types of files that had been used on human teeth. T...
