The machine made carpet industry is one of the main and most famous industries in Iran and especially in the city of Yazd. However there is little information about customer preferences for different attributes of this product. In this article we tried to estimate the relative importance of the main attributes affecting customer desire for purchasing machine made carpet and the utility values f...

In this paper, we present multi-attribute decision-making problem with neutrosophic assessment. We assume that the information about attribute weights is incompletely known or completely unknown. The ratings of alternatives with respect to each attributes are considered as single-valued neutrosophic set to catch up imprecise or vague information. Neutrosophic set is characterized by three indep...

application of automatic systems, including discharge measurement technology is one of the effective methods for improving delivery management, water use efficiency, flexibility, and performance of irrigation networks. several aspects such as hydraulic, technical, physical, environmental, economic, social, and managerial, have significant impact on these systems selection. due to diversity of t...

The increasing intensity of global competition and the rapid advances in information technology (IT) have led organisations to search for more efficient and effective ways to manage their business. With the rapid growth of IT and global complexity, selecting information system projects that further business objectives has become a complex task. This complexity is due to a larger number of alter...

This paper proposes a spatial clustering model based on self-organizing feature map and a composite distance measure, and studies the knowledge discovery from spatial database of spatial objects with non-spatial attributes. This paper gives the structure, algorithm of the spatial clustering model based on SOFM. We put forward a composite clustering statistic, which is calculated by both geograp...

The paper considers techniques for grouping objects that are described with many quantitative and qualitative attributes and may exist in several copies. Such multi-attribute objects may be represented as multisets or sets with repeating elements. Multiset characteristics and operations under an arbitrary number of multisets are determined. The various options for the objects’ aggregation (addi...

Key agreement allows multi-parties exchanging public information to create a common secret key that is known only to those entities over an insecure network. In recent years, several identity-based authenticated key agreement protocols have been proposed. In this study, we analyze three identity-based tripartite authenticated key agreement protocols. After the analysis, we found that these prot...

In this paper, we present a method based on Formal Concept Analysis (FCA) for mining numerical data. An adaptation of standard FCA Galois connection takes into account “similarity” between numerical values of attributes and leads to the definition of many-valued (MV) formal concepts and concept lattices. Depending on a similarity threshold, many-valued concept lattices have different levels of ...

Background: Hyperspectral image analysis is a fast and non-destructive technique that is being used to measure quality attributes of food products. This research investigated the feasibility of predicting internal quality attributes, such as Total Soluble Solids (TSS), pH, Titratable Acidity (TA), and maturity index (TSS/TA); and external quality attributes such as color components (L*, a*, b*)...

allamah tabatabai interprets the doctrine of attributive monotheism of god under the philosophical theory of the identity of god’s perfection attributes with his essence. because, in his view point, it is the only rational way for explanation of attributive monotheism. according to this theory, all divine perfection attributes are identical with each other and with god’s nature in external worl...
