Ensemble methods of machine learning combine neural networks or other models in order to improve predictive performance. The proposed ensemble method is based on Occam’s razor idea...

This study aims to investigate the effects of geometric imperfections on buckling of thin cylindrical shells due to global shear. To this end, more than 320 finite element models of cylindrical shells with different diameter to thickness ratios were prepared. Random imperfections with different amplitudes were applied to numerical models. The results revealed that global buckling of cylindrical...

Background: Marine pollution is a global environmental problem that its monitoring by ideal biomonitors is of great importance. Marine organisms, especially mussels, have the ability to accumulate metals from the environment they can be considered as a biomonitoring agent. Methods: In this study, concentrations of heavy metals were measured in Saccostrea cucullata collected from seven sites on...

The present study aims at investigating stress and deformation behavior of rotating thick truncated conical shells subjected to variable internal pressure. Material prpperties of the shells are graded along the axial direction by Mori-tanaka scheme, which is achieved by elemental gradation of the properties.Governing equations are derived using principle of stsionary total potential (PSTP) and ...

Many types of seafood require cooking before ingestion and it has been demonstrated that this cooking process may affect the antigenicity and allergenicity of the food. We describe a case of anaphylaxis caused by selective sensitization to razor shell, a mollusc. In vivo and in vitro studies confirmed sensitization to boiled razor shell. Analysis of the nature of the allergen yielded results th...

We describe Razor, a planning-based information-gathering agent that assists users by automatically determining which Internet information sites are relevant to their query, accessing those sites in parallel, and integrating the results. Razor uses a disjunctive graphbased plan representation. It then uses a novel and powerful form of local completeness reasoning in order to transform those pla...

A parametric study was carried out in order to investigate the buckling capacity of the vertically stiffened cylindrical shells. To this end ANSYS software was used. Cylindrical steel shells with different yield stresses, diameter-to-thickness ratios (D/t) and number of stiffeners were modeled and their buckling capacities were calculated by displacement control nonlinear static analysis.  Radi...

Fig. 1. Allergic nickel dermatitis caused by nickel release from an electric shaver. Nickel allergy is frequent in adult Danes and dermatitis patients (1, 2). The high prevalence is mostly explained by consumer exposure to products that release nickel, e.g. watches, jewellery, buttons, zips, rivets and mobile phones (3–8). It has been debated whether classic dry electric shavers may cause nicke...

This research was conducted to evaluate the possibility using peanut shells compost as a suitable medium in cultivating ornamental plants. Effect of peanut shells composts on the growth of Viola tricolor and marigold was investigated during seven months. Peat + perlite (with a ratio of 2:1) used as control treatment and peat replaced by 25, 50, 75 and 100 % v/v of peanut shells compost. Plant g...
