Detection of Corrosion Defects in Steel Bridges by Machine Vision
No full textExisting bridges are critical components of transportation infrastructure manly due to a huge volume of different corrosion. Corrosion reduced the performances of bridges and decrease their life services. Towards automatic detection of corrosion defects during inspections, a novel methodology is here proposed making use of machine vision concepts. Indeed, different types of corrosion can be detected by image processing techniques that can be an appropriate tool also for the prediction of the damage evolution in bridges. Clustering K-means algorithms on image segmentation have been used to classify corrosion defect levels

F. Shameli, deposited in APAS. Etymology. The species is named in honour of Professor Maria Lordes Moraza for her valuable works on Acari, especially Mesostigmata. Remarks. Laelaspis morazae is unique in Laelaspis by the presence of two setae pl on genu IV vs. only one seta pl in previously described species of the genus for which we have information about their leg chaetotaxy. This contrasts with L. persicus which has no pl on genu IV. It can further be distinguished from other members of the genus, except for L. latanalis and L. imitatus, by the presence of 40 pairs of setae on dorsal shield in female, including three pairs of setae Px and only two unpaired setae Jx. Note that the male of L. morazae has 39 pairs of setae on the dorsal shield, lacking Px 4, and has three Jx. The new species, L. morazae, differs from L. latanalis by the shape of genitiventral and anal shields (genitiventral shield of L. morazae is conspicuously narrower than L. latanalis and also posteriorly widely tapered, instead of wider subrectangular shield past coxae IV in L. latanalis); the anal shield in L. morazae is slightly longer than wide, but anal shield of L. latanalis is almost twice broader than long, also there are 12 pairs of setae on opisthogastric soft integument in L. latanalis instead of 17 in the new species. The new species can be easily distinguished from L. imitatus by its shorter dorsal setae (dorsal setae in L. imitatus usually reach or pass the following setal base), shape of the genitiventral shield, its median cells and location of setae JV 1, as the shield is posteriorly widely rounded in L. imitatus, but gradually tapered past widest point and posteriorly subtriangular in L. morazae. The median cells in the news species are irregular in shape and size, but in L. imitatus they are as normal for the genus; setae JV 1 situated at the broadest point in L. imitatus vs. behind it in L. morazae, postanal seta in L. morazae is barbed vs. smooth in L. imitatus, hind edge of peritrematal shields do not reach to posterior edge of parapodals in L. morazae, vs. past the posterior edge of parapodals in L. imitatus, in L. morazae length/width ratio of anal shield≈ 1 / 1 –1.3 vs. L/W ratio in L. imitatus ≈ 0.8–0.85, setae ad 1 on femora II-IV in L. morazae not thickened and also not close to distal margin of leg segment, vs. thickened and close to the margin in L. imitatus.Published as part of Kazemi, Shahrooz, 2015, A new species of Laelaspis Berlese (Acari: Mesostigmata: Laelapidae) from Iran, with a revised generic concept and notes on significant morphological attributes in the genus, pp. 411-428 in Zootaxa 4044 (3) on pages 420-425, DOI: 10.11646/zootaxa.4044.3.5, http://zenodo.org/record/24184

Seismic damage diagnosis in adjacent steel and RC MRFs considering pounding effects through improved wavelet-based damage-sensitive feature
No full textThis paper aims to propose complex Morlet (cmorfb-fc) wavelet-based refined damage-sensitive feature (rDSF) as a new and more precise damage indicator to diagnose seismic damages in adjacent steel and Reinforced Concrete (RC) Moment Resisting Frames (MRFs) assuming pounding conditions using acceleration responses. The considered structures include 6- and 9-story steel and 4- and 8-story RC benchmark MRFs that are assumed to have different values of separation distances, δMT, calculated according to the ASCE 7-10 seismic provision. For the sake of pounding modelling, linear viscoelastic contact elements among the pounding structures are assumed. Furthermore, an algorithm is developed to compute the seismic collapse capacities of each pounding MRF through Incremental Dynamic Analyses (IDA) using OpenSees software. In the next step, auto-regressive moving-average with exogenous input (ARX) model together with a stabilization diagram is utilized to appraise the natural frequencies of each adjacent MRF. Shannon entropies and correlation coefficient (ρ) are used to select the best cmorfb-fc wavelet. Based on the results, damage resulting from pounding effects can be accurately detected in both cases of with and without δMT, especially for steel MRFs
Results on varextropy measure of random variables
No full textIn 2015, Lad, Sanfilippo and Agrò proposed an alternative measure of uncertainty dual to the entropy known as extropy. This paper provides some results on a dispersion measure of extropy of random variables which is called varextropy and studies several properties of this concept. Especially, the varextropy measure of residual and past lifetimes, order statistics, record values and proportional hazard rate models are discussed. Moreover, the conditional varextropy is considered and some properties of this measure are studied. Finally, a new stochastic comparison method, named varextropy ordering, is introduced and some of its properties are presented
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Fractional deng entropy and extropy and some applications
No full textDeng entropy and extropy are two measures useful in the Dempster–Shafer evidence theory (DST) to study uncertainty, following the idea that extropy is the dual concept of entropy. In this paper, we present their fractional versions named fractional Deng entropy and extropy and compare them to other measures in the framework of DST. Here, we study the maximum for both of them and give several examples. Finally, we analyze a problem of classification in pattern recognition in order to highlight the importance of these new measures
Dataset of plasmid DNA extraction using different magnetic nanoparticles (MNPs)
No full textAbstractIn this dataset we integrated figures related to bacterial transformation using pBI121 plasmid and complementary analysis for magnetic nanoparticles (MNPs) characterizations. The structural map of pBI121 plasmid was drawn by Vector NTI software using the complete sequence of binary vector pBI121. Escherichia coli bacteria transformed using pBI121 plasmid and were grown on the selection media containing kanamycin.MNPs were characterized by energy dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). Finally, the overall efficiency of different MNPs (Fe3O4, Fe3O4/SiO2, Fe3O4/SiO2/TiO2) in plasmid DNA isolation was compared using gel electrophoresis analysis. The data supplied in this article supports the accompanying publication “Comparative study of three magnetic nano-particles (FeSO4, FeSO4/SiO2, FeSO4/SiO2/TiO2) in plasmid DNA extraction” (H. Rahnama, A. Sattarzadeh, F. Kazemi, N. Ahmadi, F. Sanjarian, Z. Zand, 2016) [1]
