indoor radon concentration (irc) is among the emerging environmental and health issues in republic of korea. due to lack of epidemiological studies and insufficient public awareness about radon, effective parameter ranking system is required to establish protocols for future field sampling and settlement construction. this research propose the irc parameter ranking system based on field measure...

Several rule discovery algorithms have the disadvantage to discover too much patterns sometimes obvious, useless or not very interesting to the user. In this paper we propose a new approach for patterns ranking according to their unexpectedness using semantic distance calculated based on a prior background knowledge represented by domain ontology organized as DAG (Directed Acyclic Graph) hierar...

A new method for ranking the output of the superimposed variation of the signature file method (SC/SF) is presented. The method is termed 'Binary Ranking' and assigns a value ('B-rank value') to each block candidacy of the signature file output in a way which reflects the credibility of the signature to stand in place of the corresponding real text. In order to measure the performance of the pr...

“The PyImageQualityRanking software’s source code can be downloaded from https://bitbucket.org/sakoho81/ pyimagequalityranking/. The software is distributed as a standard Python package, which contains an automatic setup script for easy installation. A convenient command line interface is provided for controlling various measures. For further details, please refer to the software documentation ...

In this paper, we address the efficiency of implementing the tf x idf ranking strategy with inverted files. Two search methods are studied. The first one sorts postings lists of query terms based upon the list length. It is the traditional sorting method used in the upperbound search algorithm. The second one sorts postings lists based upon the maximum tf as well as the list length. We show tha...

Guiding characteristics along with field distributions for different modes in a rectangular waveguide are numerically estimated using HFSS software when it is placed in free space. A comparative analysis is made for propagation constant, guided wavelength and characteristic impedance at C, X and Ku band to observe the deviation from well-known theoretical profiles. Strength of electric and magn...

One of the drawbacks of Data Envelopment Analysis (DEA) is the problem of lack of discrimination among efficient Decision Making Units (DMUs). A method for removing this difficulty is called changing reference set proposed by Jahanshahloo and et.al (2007). The method has some drawbacks. In this paper a modified method and new method to overcome this problems are suggested. The main advantage of...
