Clustering algorithms are highly dependent on different factors such as the number of clusters, the specific clustering algorithm, and the used distance measure. Inspired from ensemble classification, one approach to reduce the effect of these factors on the final clustering is ensemble clustering. Since weighting the base classifiers has been a successful idea in ensemble classification, in th...
Ultra-Violet (UV) radiation covers the spectrum of wavelengths from 100 to 400 nm. The potency and biological activity for a variety of endpoints differ by wavelength. For monitoring and communication purposes, different UV action spectra have been developed. These spectra use different weighting functions. The action spectrum for erythemal dose is the most widely used one. This erythemal dose ...
The Economic Freedom of the World (EFW) index is extensively used in academic research to show how economic freedom relates to a wide array of economic and social outcomes. Given this, it is important that researchers understand the goal of the index and how to properly utilize this index in their research. There seem to be several common misconceptions about the EFW index resulting from a simp...
PURPOSE The goal of this paper is to extend our recently developed FBP (filtered backprojection) algorithm, which has the same characteristics of an iterative Landweber algorithm, to an FBP algorithm with the same characteristics of an iterative MAP (maximum a posteriori) algorithm. The newly developed FBP algorithm also works when the angular sampling interval is not uniform. The projection no...
The Islamic Republic of Iran Vision aimed to direct development plans and yearly budgets. As one of the most important part, it includes 13 economic goals for directing economic route of the country for a twenty years period. After 15 years, evaluating how the country achieved to these goals is very important and unfortunately neglected. In this article, considering the different nature of goal...
Filtration index of the drilling fluid is an important parameter of well drilling, especially at drilling-in the reservoirs. Standard parameter in the study of drilling fluids is static filtration index. At the same time, it is more feasible to determine dynamic filtration index, if considering actual conditions of the well. Use of polymer carbonate-weighted drilling fluids is advisable at dril...
Modern retrieval approaches apply not just single-term weighting models when ranking documents instead, proximity weighting models are in common use, which highly score the co-occurrence of pairs of query terms in close proximity to each other in documents. The adoption of these proximity weighting models can cause a computational overhead when documents are scored, negatively impacting the eff...
