Background: Since Tehran University of Medical Sciences (TUMS) has the oldest and highest number of research centers among all Iranian medical universities, this study was conducted to evaluate scientific output of research centers affiliated to Tehran University of Medical Sciences (TUMS) using scientometric indices and the affecting factors. Moreover, a number of scientometric indicators we...

this study historically analyzes the scientific output of mathematics to describe its structure, notions and scientific origin using the historiographical method. the research data consisted of scientific outputs of mathematics in isi database, science citation index (sci) and social science citation index (ssci) during 8 years (1990 to 2007). the data collection tool was the search engine and ...

Automobile sector forms the backbone of manufacturing sector. Vehicle assembly line is important section in automobile plant where repetitive tasks are performed one after another at different workstations. In this thesis, a methodology is proposed to reduce cycle time and time loss due to important factors like equipment failure, shortage of inventory, absenteeism, set-up, material handling, r...

The use of digital technologies within research has led to a proliferation of data, many new forms of research output and new modes of presentation and analysis. Many scientific communities are struggling with the challenge of how to manage the terabytes of data and new forms of output, they are producing. They are also under increasing pressure from funding organizations to publish their raw d...

Recent reports suggest that, during the 1990s, the EU15 overcame the US as the world largest scientific producing block. In this paper we perform a comprehensive comparative analysis of the evolution of the EU15 and US scientific output and impact throughout the 1990s looking at publications and impact trends by scientific field. Results show that changes of scientific production between the tw...

Linked Open Datasets about scholarly publications enable the development and integration of sophisticated end-user services; however, richer datasets are still needed. The first goal of this Challenge was to investigate novel approaches to obtain such semantic data. In particular, we were seeking methods and tools to extract information from scholarly publications, to publish it as LOD, and to ...

We investigate the problem of counting co-authorhip in order to quantify the impact and relevance of scientific research output through normalized h-index and g-index. We use the papers whose authors belong to a subset of full professors of the Italian Settore Scientifico Disciplinare (SSD) FIS01 Experimental Physics. In this SSD two populations, characterized by the number of co-authors of eac...

Classifying researchers according to the quality of their published work rather than the quantity is a curtail issue. We attempt to introduce a new formula of the percentage range to be used for evaluating qualitatively the researchers' production. The suggested equation depends on the number of the singleauthor published papers and their citations to be added as a new factor to the known h-ind...
