This study provided a comparative analysis of three social network sites, the open-to-all Facebook, the professionally oriented LinkedIn and the exclusive, members-only ASmallWorld.The analysis focused on the underlying structure or architecture of these sites, on the premise that it may set the tone for particular types of interaction.Through this comparative examination, four themes emerged, ...

In this paper we propose a consistent and asymptotically normal estimator (CAN) of intensities 1  , 2  for a queueing network with feedback (in which a job may return to previously visited nodes) with distribution-free inter-arrival and service times. Using this estimator and its estimated variance, some   100 1 %   asymptotic confidence intervals of intensities are constructed. Also boot...

The efficiency of routing protocols in general mobile ad hoc networks may be highly affected by the specific Medium Access Control scheme the routing relies upon and by the mobility of the wireless nodes. In this work, we address the design of position based routing solutions for the support of safety oriented applications in Vehicular Ad hoc NETworks (VANETs) by focusing on the impact of the M...

This study applies scientometric approach to meso level data. The objective was to evaluate Institutional level hindex’s (IHI) reliability with respect to other Journal Related Indices (JRI). Most of the studies in the literature considered journal’s h-index as contrasted measure. Nevertheless, there has been no study that explores the relation between IHI and institutional level JRI. To get fu...

Data streams mining has become interesting research topic and growing interest in knowledge discovery process. Because of the high speed and huge size of data and mining is processed with limited computing power and limited memory storage capabilities. Therefore our traditional classification technique are not directly applicable. Classification of data stream is more challenging task due to fo...

As there is increasingly high advancement in technology, so Question Answering is becoming major area of research for the researchers. Different queries are provided by the user in aim of getting accurate answers in Question Answering Systems. Question Answering provides perfect solution to retrieve valid and accurate answers to user question asked in natural language instead of query. Hindi, T...

Edge detection is one of the most commonly used operations in image analysis. Several edge detectors have been proposed in literature for enhancing and detecting of edges. In this paper a new and optimal approach of edge detection based on Cellular Automata (CA) has been proposed. The idea is simple but effective technique for edge detection that greatly improves the performances of complicated...

In many businesses, including hydrocarbon industries, reducing cost is of high priority. Although hydrocarbon industries appear able to afford the expensive computing infrastructure and software packages used to process seismic data in the search for hydrocarbon traps, it is always imperative to find ways to minimize cost. Seismic processing costs can be significantly reduced by using inexpensi...

Background: application of an American early language test in Brazilian Portuguese-speaking subjects. Aim: to compare the performance of normal Brazilian Portuguese and American English-speaking subjects on the Test of Early Language Development Third Edition (TELD-3). Method: participants of this study were 120 subjects of both genders, ranging in age from 2:00 to 7:11 years (20 subjects in ea...

This paper proposed an integrated model of combining Berth Allocation Problems (BAP) and Quay Cranes Assignments (QCA). It aims to improve terminal performances by minimizing the total service time and vessel transfer rate, especially for those important customers (vessels). A Two-Level Genetic Algorithm (TLGA) approach was proposed for solving the problems. A number of experiments were conduct...
