Abstract The regulation of water companies (WCs) is essential to protect the interests citizens, as are natural monopolies. Consequently, several methodological approaches applied by regulators benchmark performance WCs, with data envelopment analysis (DEA) being one most widely applied. However, traditional DEA models allocate different weights variables considered in efficiency assessments ea...

Data Envelopment Analysis (DEA) deals with evaluating a set of decision-making units (DMUs) based on nonparametric mathematical approaches. In classical DEA models, the given set of factors of DMUs is divided into two categories, inputs and outputs, while in some practical problems there are some measures whose membership to these categories is unclear. It means these factors treat different in...

The OpenGIS Catalogue Services (CS) specification defines a set of abstract interfaces for the discovery, access, maintenance and organization of metadata repositories of geospatial information and related resources in distributed computing scenarios, such as the Web. The CS specification also defines a HTTP protocol binding, which is called “Catalogue Services for the Web” or CSW. A fair descr...

The paper presents a semantic approach for storing and retrieving documents from a Corporate Semantic Web (CSW). We illustrate the approach through the embedding of two graphs G1 into G2. G1 represents the CSW and whose nodes represent a collection of documents having a common range of semantic indices. G2 represents a P2P storage network. We use ”Ant Colony Optimization” metaheuristic, to solv...

The SRC homology 2 (SH2) domain protein-tyrosine phosphatase, Corkscrew (CSW) is required for signaling by receptor tyrosine kinases, including the Sevenless receptor tyrosine kinase (SEV), which directs Drosophila R7 photoreceptor cell development. To investigate the role of the different domains of CSW, we constructed domain-specific csw mutations and assayed their effects on CSW function. Ou...

The TMT Software System consists of software components that interact with one another through a software infrastructure called TMT Common Software (CSW). CSW consists of software services and library code that is used by developers to create the subsystems and components that participate in the software system. CSW also defines the types of components that can be constructed and their roles. T...

There are several methods to ranking DMUs in Data Envelopment Analysis (DEA) and candidates in voting system. This paper proposes a new two phases method based on DEA’s concepts. The first phase presents an aspiration rank for each candidate and second phase propose final ranking.

Data Envelopment Analysis (DEA) is the most popular mathematical approach to assess efficiency of decision-making units (DMUs). In complex organizations, DMUs face a heterogeneous condition regarding environmental factors which affect their efficiencies. When there are large number objects, non-homogeneity significantly influences scores that leads unfair ranking DMUs. The aim this study deal w...

Corkscrew (csw) encodes a nonreceptor protein tyrosine phosphatase (PTPase) that has been implicated in signaling from the Torso receptor tyrosine kinase (RTK). csw mutations, unlike tor mutations, are associated with zygotic lethality, indicating that Csw plays additional roles during development. We have conducted a detailed phenotypic analysis of csw mutations to identify these additional fu...

Abstract Micro, small and medium enterprises (MSMEs) dominate the business landscape create more than half of employment worldwide. How we can apply big data analytical tools such as machine learning to examine performance MSMEs has become an important question provide quicker results recommend better reliable solutions that improve performance. This paper proposes a novel method for estimating...
