The concentrations of rare-earth elements (REEs) were determined with the aim of investigating the behavior of these elements in granitic rock, granitic soils and soils between rock and lichen in Shir-kuh of Yazd province. Rare earth element patterns of the P-rich granite were determined by the mixture of Eu-enriched feldspars, middle REEs to heavy REEs-enriched apatite and Light REEs-enriched ...

In this study, centrifugal casting process was used for producing Al/Mg bimetal. Molten Mg was poured at 700 oC, with 1.5 and 3 melt-to-solid volume ratio (Vm/Vs) into the 450 oC preheated solid Al rotating at 800, 1200, 1600 and 2000 rpm. Castings were kept inside the centrifuged casting machine and cooled down to 150 oC. Investigating the effect of melt-to-solid volume ratio showed that incre...

A numerical framework has been proposed to model the interacting effects of mixture non-ideality and mass transfer on hydrodynamics of a multiphase system using CFD methods.Mass transfer during condensation and vaporization is modeled by chemical potential at the liquid-vapor interface. Species mass transfers are related to the diffusion at the interface which in turn is related to the conc...

A numerical dynamic-aerodynamic interface for simulating the separation dy­n­a­m­ic­s of co­n­­s­t­r­a­i­ned strap-on boosters jettisoned in the atmosphere is presented. A 6-DOF multi body dynamic solver ،using Constraint For­ce Equation Methodology is coupled with a numerical time dependent Euler flow solver. An automatic dyna­m­i­­c mesh updating proc­e­d­ure is employed using smoothing and l...

For the creation of efficient and robust BrainComputer Interfaces (BCIs) based on the detection of eventrelated potentials (ERPs) in the electroencephalogram (EEG), spatial filtering has been shown as being an important step for feature extraction and reduction. Current spatial filtering methods for ERP enhancement typically consider a global approach by enhancing the signal on a predefined tim...

Individual differences across subjects and nonstationary characteristic of electroencephalography (EEG) limit the generalization of affective braincomputer interfaces in real-world applications. On the other hand, it is very time consuming and expensive to acquire a large number of subjectspecific labeled data for learning subject-specific models. In this paper, we propose to build personalized...

This research describes the unsteady two-dimensional reacting flows around a circular cylinder. The numerical solution combines the random vortex method for incompressible two-dimensional viscous fluid flow with a Simple Line Interface Calculation (SLIC) algorithm for the propagation of flame interface. To simplify the governing equations, two fundamental assumptions namely Low Mach Number and ...

عامل تغییرشکل پذیری خاک علاوه بر تغییر خصوصیات حرکت آزاد زمین در سطح، ممکن است به علت اندرکنش با سازه تغییرات قابل ملاحظه ای در واکنش سازه ایجاد نماید. رفتار غیرخطی خاک تحت بارهای چرخه ای با شدت تخریبی زیاد، بسیار محتمل است. با این حال در بیشتر مدل سازی ها و تحقیقات انجام شده روی سیستم خاک و سازه، رفتار خاک الاستیک و یا الاستو-پلاستیک در نظرگرفته شده است. هدف از این تحقیق، بررسی اثر اندرکنش خا...

Introduction: The e-prescribing system is one of the basic technologies in the health system structure which was developed with the aim of properly managing healthcare resources and services, preventing common manual prescribing errors, and increasing patient safety. Given that the user interface of e-prescribing system is considered as the main factor of user acceptance, the purpose of the pre...

Abstract: The purpose of this study is to produce scarf joint through explosive welding process (EXW). The scarf weld is a process in which the final bond interface is oblique. With applying the explosive welding technique, this joint can create a metallic bond between similar or dissimilar metals. In this study, chamfered end of aluminum and copper plates were joined explosively and named scar...
