Using set operators

The rest of the paper is organized as follows: In the next section, we recall the concept of picture fuzzy set and several operators of two picture fuzzy sets. We then propose a new MCDM method using the dissimilarity measure of picture fuzzy sets. Finally, we apply the proposed method for evaluating water reuse applications.

The purpose of this paper is to study the characteristics of competitiveness in firms’ sectors of the Greek manufacturing industry, based on firm level accounting and qualitative data attempting to identify key issues regarding Greek SMEs. An unbalanced data set of 407 Greek manufacturing SMEs is implemented, covering the period of 2003-2011 with the use of a multivariate regression model (EGLS) with explanatory variables characterizing firms’ operational activity.

This research is a single case study of the impact of the introduction of both information technology (software, hardware and Internet) and a company policy about IT use on the internal operations of a fire truck assembly company and its supply chain relationships. Using Action Research, the research focuses on a fire truck assembly company in Thailand, where supply chain efficiency was not improving and where costs of, and relationships with, both upstream suppliers and downstream clients in the supply chain were increasing.

This computerized study of the homonyms of elementary words (roughly equivalent to monosyllabic words) has allowed the compilation of exhaustive lists of homonym sets, using phonetic transcriptions from five different dictionaries. Of the 5,757 elementary words, 2,966 were involved in at least one homonym set, indicating that homonyms will present a significant problem in.

THE UNIVERSITY OF MICHIGAN undertook research, late in 1955, in the analysis of language structure for mechanical translation. Emphasis was placed on the use of the contextual structure of the sentence as a means of reducing ambiguity and on the formulation of a set of operative rules which an electronic computer could use for automatically translating Russian texts into English.

Globalization Support Features Globalization Support ensures that database utilities and error messages, sort order, date, time, monetary, numeric, and calendar conventions automatically adapt to the native language. Oracle currently supports 57 languages, 88 territories, 84 linguistic sorts (71 monolingual and 13 multilingual), and 235 encoded character sets. The language-dependent operations are controlled by a number of parameters and environment variables on both the client and the server sides. The server and the client may run in the same or different locations.

Users and Security Security domain The database administrator defines the names of the users who are allowed to access a database. A security domain defines the settings that apply to the user. Authentication mechanism A user who requires access to the database can be authenticated by one of the following: Data dictionary Operating system Network The means of authentication is specified at the time the user is defined in the database and can be altered later. This lesson covers authentication by database and by operating system only.

Before a database is created, the UNIX environment must be configured and the Oracle9i server must have already been installed. Four environment variables must be set: ORACLE_HOME, ORACLE_SID, PATH, LD_LIBRARY_PATH. ORACLE_HOME is the full path to the top directory in which the Oracle9i Server is installed. The directory for ORACLE_HOME should be supplied by the person who installed the server, usually the UNIX administrator or the DBA. ORACLE_SID is a user-definable name assigned to an instance of a database.

Security-Enhanced Linux (SELinux) is an implementation of mandatory access control using Linux Security Modules (LSM) in the Linux kernel, based on the principle of least privilege. It is not a Linux distribution, but rather a set of modifications that can be applied to Unix-like operating systems, such as Linux and BSD.

Let X be a compact K¨hler manifold with strictly pseudoconvex bounda ary, Y. In this setting, the SpinC Dirac operator is canonically identified with ¯ ¯ ∂ + ∂ ∗ : C ∞ (X; Λ0,e ) → C ∞ (X; Λ0,o ). We consider modifications of the classi¯ cal ∂-Neumann conditions that define Fredholm problems for the SpinC Dirac operator. In Part 2, [7], we use boundary layer methods to obtain subelliptic estimates for these boundary value problems. Using these results, we obtain an expression for the finite part of the holomorphic Euler characteristic of a strictly pseudoconvex manifold...

We provide a class of necessary and sufficient conditions for the discreteness of spectrum of Schr¨dinger operators with scalar potentials which o are semibounded below. The classical discreteness of spectrum criterion by A. M. Molchanov (1953) uses a notion of negligible set in a cube as a set whose Wiener capacity is less than a small constant times the capacity of the cube. We prove that this constant can be taken arbitrarily between 0 and 1. This solves a problem formulated by I. M. Gelfand in 1953. Moreover, we extend the notion of negligibility by allowing the constant to...
