groundwater is the sole source of accessible resource for agriculture in zeviercherry- kherran plains and water quality often falls in brackish group. in order to determine the source of salinity and hydrochemical processess affecting groundwater environment of the area, 61 groundwater samples were taken for hydrochemical analysis and composite diagrams (two variant diagrams of total concentrat...

This paper highlights the importance of software maintenance, specifically the UML (Unified Modeling Language) diagrams, created and changed, especially during the tasks of analysis and design of software. The main idea of this paper is to formalize the software maintenance phase in order to motivate the maintenance documentation of these diagrams taking into account a knowledge base which repr...

Multimedia presentations typically produce better memory and understanding than do single-medium presentations. Little research, however, has considered the effect of multimedia on memory for nonmultimedia information within a large multimedia presentation (e.g., nondepicted text in a large text with diagrams). To this end, the present two experiments compared memory for target text information...

The present study investigates the question of whether and how Euler diagrams can improve syllogistic reasoning. Previous research reports that there is no evidence to show the psychological advantage of Euler diagrams in solving syllogisms. In our experiments, we use Euler diagrams with “named points”, which are formulated within the simple Euler system introduced in our previous work. The dia...

Pericyclic reaction theory arose from ideas presented in 1965, based on orbital-energy correlation diagrams (Woodward and Hoffmann) and state-energy correlation diagrams (Longuet-Higgins and Abrahamson). Here we have used ab initio complete-active-space self-consistent field (CASSCF) calculations to generate such diagrams. First we present diagrams for the classic case of cyclobutene ring openi...

This paper presents a natural language processing based automated system for generating UML diagrams after analyzing the given business scenario. A new model is presented for analyzing the natural languages and extracting the relative and required information from the given storyline by the user. User writes the requirements in simple English in a few paragraphs and the designed system has cons...
