Spatial predictions of soil moisture content in arid lands are necessary for soil survey, land evaluation, hydrological modeling, land use planning and sustainable land use. Multiple-linear regression models with land use and terrain indices were developed to spatially predict soil moisture using six methods. The performance of six models was evaluated using 13 indices based on biweekly-measure...

Compared with various information-hiding techniques on the spatial domain proposed previously, VQ-based information hiding technique has not been paid much attention. As a result, we present a steganographic scheme based on the search-order coding (SOC) compression method of vector quantization (VQ) indices in this paper. The major goal is to embed secret data into the compression codes of the ...

The concept of classifying the records of the information system has been due to Two Way Approach [ ie, lower and upper approximations ] of Pawlak’s rough sets model. But the approximation does to take into consideration the degree of contribution of the basic categories. This deficiency was eliminated in early nineties by Ziarko who has proposed VPRS model and later on various efforts were mad...

This paper presents a multi-mode indexing scheme for effective content-based image retrieval. Three types of indices are identified: visual indices for quantifiable visual information, semantic indices for non-quantifiable semantic information, keywords indices for keywords or free text. The underlying index structures are the HG-tree and the signature file. The HG-tree is one of the most promi...

The Coronary Artery Surgery Study, CASS, enrolled 24,959 patients between August 1975 and June 1979 who were studied angiographically for suspected coronary artery disease. This paper compares the prognostic value for survival without early elective surgery of eight different indices of the extent of coronary artery disease: the number of diseased vessels, two indices using the number of proxim...

This report discusses two new indices for comparing clusterings of a set of points. The motivation for looking at new ways for comparing clusterings stems from the fact that the existing clustering indices are based on set cardinality alone and do not consider the positions of data points. The new indices, namely, the Random Walk index (RWI) and Variation of Information with Neighbors (VIN), ar...

nowadays, by the expansion of information technology in human life and dependence of business upon it, data protection, as one the most valuable and critical assets of the organization, has become the vital tool of modern industry and prerequisite for sustaining business process. in order to face the challenges and to take advantage of new opportunities brought forth by it advances we suggest o...

Information retrieval systems based on conceptual indexing can access the underlying meaning of text, graphics or videotaped documents. Since conceptual indices represent the semantics of a piece of information, it is difficult to extract them automatically from a document, and it is tedious to build them manually. We present a method to acquire and refine conceptual indices in the context of D...

Fifteen compounds reported to be inhibitors of gelation or sickling were studied by standard methods. These tests included (1) the determination of the solubility of deoxyhemoglobin S or Csat, (2) evaluation of sickling in whole SS blood at various pO2s, (3) measurement of the oxygen affinity of hemoglobin and blood, and (4) examination of red cell indices and morphology. Among the 4 noncovalen...
