As an advanced process detection technology, electrical impedance tomography (EIT) has widely been paid attention to and studied in the industrial fields. But the EIT techniques are greatly limited to the low spatial resolutions. This problem may result from the incorrect preprocessing of measuring data and lack of general criterion to evaluate different preprocessing processes. In this paper, ...

Eugene Garfield’s article, “Citation indexes for science” [Science 122, 108 (1955)], is interesting beyond doubt. If we had in our library a citation index such as he proposes, I should use it to advantage. Amid today’s overwhelming difficulties in scientific communication, however, this index would solve too few problems to justify its surely great cost at this time. Even though all the cited ...

In this work, the particle swarm optimization method is employed for the reliability-based optimal design of statically determinate truss structures. Particle swarm optimization is inspired by the social behavior of flocks swarms of birds and insects particles . Every particle’s position represents a specific design. The algorithm searches the design space by adjusting the trajectories of the p...

Various indexes are being used today to evaluate the strength of passwords. In these indexes, a password is evaluated be high if it takes longer for an attacker predict it. Therefore, using such evaluation, there problem that leaked may reduce reliability index by increasing vulnerability attempts attack password. Hence, estimating frequency when considering important reducing vulnerability. Th...

This paper proposes a new methodology to build composite coincident and leading indexes. Based on a formal definition that requires that the first differences of the leading index is the best linear predictor of the first differences of the coincident index, it is shown that the notion of polynomial serial correlation common features can be used to build these composite variables. Concepts and ...

Prais (1958) showed that the standard CPI computed by most statistical agencies can be interpreted as a weighted average of household price indexes, where the weight of each household is determined by its total expenditures. In this paper, we decompose the difference between the standard CPI and a democratically weighted index (i.e., the CPI plutocratic gap) as the product of expenditure inequa...

The present study investigated and analyzed the clinical impact of sublobectomy on pulmonary functions.Changes in pulmonary function before and after sublobectomy were compared to the changes after lobectomy.Changes in the pulmonary function before and after sublobectomy and lobectomy did not exhibit remarkable differences in long-term effects. Surgery-related indexes of the sublobectomy group ...

Based on social network perspective, we developed a model about the knowledge sharing of communities of practice (CoPs), analyzed the knowledge sharing of CoPs from the view of the network density, network centrality, network structure. And we found out that only the above indexes are kept in appropriately level can stimulate the knowledge sharing in CoPs. The strong ties contribute to the tran...

A secure index is a data structure that allows a querier with a " trapdoor " for a word x to test in O(1) time only if the index contains x; The index reveals no information about its contents without valid trapdoors, and trapdoors can only be generated with a secret key. Secure indexes are a natural extension of the problem of constructing data structures with privacy guarantees such as those ...
