In this paper, a divide-and-conquer algorithm for machining feature recognition over network is presented. The algorithm consists of three steps. First, decompose the part and its stock into a number of sub-objects in the client and transfer the sub-objects to the server one by one. Meanwhile, perform machining feature recognition on each sub-object using the MCSG based approach in the server i...

The purpose of this study is to better understand the digital divide by identifying the variety of ways in which people in Europe use the Internet. First, by using cluster analysis on survey data (N=12,666/age: 16–74 years) from Eurostat on Internet usage in Norway, Sweden, Austria, the UK, and Spain, we identified five user types: Non-Users (42%), Sporadic Users (18%), Instrumental Users (18%)...

Real-world problems are often too large and complex for a single monolithic system to solve. In practice, the divide-and-conquer strategy has often been used to decompose a large and complex problem into smaller tractable sub-problems and then solve them. However, good decomposition of large and complex problems requires experienced human experts and rich prior domain knowledge, which are usual...

the main purpose of this study was the bank market segmentation or in other words, dividing bank market into distinct groups of customers who might require separate marketing mix. gaining this purpose, 640 questionnaires were gathered. to investigate the reliability of questionnaires, content and face validity approaches were used. furthermore, for the estimation of the reliability of questionn...

In recent decades, international connectivity has improved significantly with the worldwide deployment of some 400 fiber submarine cables (SMCs), transmitting more than 99% telecommunications. If sub-Saharan African (SSA) long remained excluded from this interconnection process, maritime infrastructure network recently densified and spurred an catch-up. This paper estimates impact SMC on digita...

In this paper we discuss the results of a survey of senior citizens’ interaction with information technology. We expected that the “digital divide” between young and old might be diminishing, and we found evidence of that. We also report on information technologies that seem to be attracting seniors and those that have not yet attracted this age group. We also report findings with regard to sen...
