Customers use reviews, which valuable sources of information understand the public opinion on products and/or services. Dependability reviews can give rise potential concern that violator could deceitful in order synthetically promote decry and This practice is known as Opinion Spam, where spammer...

In this paper, we give a characterization of strongly Jordan zero-product preserving maps on normed algebras as a generalization of  Jordan zero-product preserving maps. In this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly Jordan zero-product preserving maps are completely different. Also, we prove that the direct p...

In this paper, we introduce the notion of a frame in a 2- inner product space and give some characterizations. These frames can be considered as a usual frame in a Hilbert space, so they share many useful properties with frames.

The aim of this paper is to define the productoperation on a family of interval valued events and the notion ofjoint interval valued observable. We show the connection betweenproduct operations for interval valued events and intuitionisticfuzzy events, too. We display the relation between joint intervalvalued observable and joint intuitionistic fuzzy observable. We...

in this paper, we investigate a problem of finding natural condition to assure the product of two graphs to be hamilton-connected. we present some sufficient and necessary conditions for $gbox h$ being hamilton-connected when $g$ is a hamilton-connected graph and $h$ is a tree or $g$ is a hamiltonian graph and $h$ is $k_2$.

new product development (npd) is described in the literature as the transformation of a market opportunity into a product available for sale. in the automotive industry, within the context of iso/ts16949:2002 (the automotive quality management system international standard),  these related to the product realization process (prp) which consists of three main phases such as planning, implementat...
