An Application of Interval-Valued Fuzzy Soft Sets in Medical Diagnosis

Abstract The concept of soft set is one of the recent topics developed for dealing with the uncertainties present in most of our real life situations. The parametrization tool of soft set theory enhance the flexibility of its applications. In this paper we extend Sanchez's approach for medical diagnosis using interval-valued fuzzy soft sets and exhibit the technique with a hypothetical case study

Modeling of WEDM Parameters while Machining Mg-SiC Metal Matrix Composite

In this paper an attempt has been made to study the effects of the process parameters of wire cut electrical discharge machining (WEDM) on Magnesium-Silicon Carbide MMC with 5% SiC in particulate form. For the analysis, six factors, namely pulse on time, pulse off time, spark gap voltage, peak current, dielectric flushing pressure and servo feed have been taken and a Taguchi L16 orthogonal array for two levels was used. Response surface methodology was also used to develop second-order models for material removal rate (MRR) and surface roughness (SR). From the analysis of variances, it has been observed that pulse on time and pulse off time were the most significant parameters among all those observed in predicting the MRR and SR, respectively

Morphological characterization of sali rice accessions of North East India

Rice is a major cereal crop of Assam, North East India. The local rice accessions grown in this region possess unique traits of breeder’s choice i.e., tolerance to biotic and abiotic stresses. In the present investigation, 712 sali rice accessions of Assam were characterized using 20 qualitative and 13 quantitative traits. Among these, 19 qualitative traits showed distinct polymorphism except for the ligule colour. The maximum polymorphism was observed for apiculus colour followed by the colour of lemma palea and sterile lemma. The significant variation for the quantitative traits was recorded among the accessions. Lakhi Bilash and Borkamal were identified as the high yielding genotypes, which may be used further in breeding programmes. The cluster analysis using morphological traits based on the Euclidean distance matrix classified the accessions into the two distinct sub-groups. The high yielding accessions were grouped together in one cluster. A significant positive correlation was observed among the grain yield with the various panicle associated traits therefore, these may be used as selection criteria for development of high yielding rice varietiies

Decision making under incompleteness based on soft set theory

[EN]Decision making with complete and accurate information is ideal but infrequent. Unfortunately, in most cases the available infor- mation is vague, imprecise, uncertain or unknown. The theory of soft sets provides an appropriate framework for decision making that may be used to deal with uncertain decisions. The aim of this paper is to propose and analyze an effective algorithm for multiple attribute decision-making based on soft set theory in an incomplete information environment, when the distribution of incomplete data is unknown. This procedure provides an accurate solution through a combinatorial study of possible cases in the unknown data. Our theoretical development is complemented by practical examples that show the feasibility and implementability of this algorithm. Moreover, we review recent research on decision making from the standpoint of the theory of soft sets under incomplete information

Effect of Quarry Dust on Compaction Characteristics of Clay

Urbanization and industrialization has lead to scarcity of land with good bearing capacities thus forcing the construction over sites deemed unsuitable for such activities. To improve the geotechnical properties of soil of such sites soil stabilization methods are adopted. Use of graded aggregates as additives to such soil followed by compaction is an old technique of mechanical soil stabilization increases the support quality of soil and also provides material economy. Sand is used for the purpose but is getting scares day by day due to its large field of application. Rock quarry dust is a solid waste product produced in large scale during crushing operations of stones and rocks to obtain aggregates. Similarity in mineral composition and inertness in structure has made it possible to use them as the graded aggregate material and suitable alternative to sand for geotechnical operations. Also bulk utilization of this waste has become necessary due to geo environmental problems related to its disposal. The objective of this paper is to investigate the effect of quarry dust addition of different gradations on the compaction behavior of clay of different compressibility. A series of light compaction tests were carried out on soil mixes prepared with different quarry dust content with a locally available clayey soil and commercially available bentonite clay. Variation in the maximum dry density (MDD) and optimum moisture content (OMC) values has been obtained with increasing content and use of different gradations of quarry dust in the two clay types. Also the compaction characteristics are compared to those of clay-sand mixes by using sand samples having similar gradation to that of quarry dust. An effort has also been made to compare the MDD-OMC relationship of soil mixes of present study to that of naturally occurring soil found in literature
