We investigate the coupled dynamics of quantized vortices and normal fluid in superfluid $^4$He at finite temperatures using a numerical approach based on vortex filament model (VFM) lattice Boltzmann method (LBM). The LBM allows us to simulate flow with only local operations, i .e., rather than solving Navier--Stokes (NS) equations directly; is considered convection mesoscopic particles betwee...

This paper presents a step towards the design of a novel test for simultaneous identification of all the stiffness components of orthotropic composite materials. A simulator was adopted to numerically simulate the whole identification process. Synthetic images were generated and then processed by Digital Image Correlation (DIC) to calculate the strain fields. The Virtual Fields Method (VFM) was...

با توجه به عدم­‌قطعیت‌های حاکم بر پروژه‌های عمرانی و تفاوت بارز آن‌ها صنایع خدماتی تولیدی از منظر محدوده زمان‌بندی کار، عوامل محیطی چالش‌های اجرایی، پیمانکاران کارفرمایان همواره اختلافات دعاوی قراردادی مواجه هستند. در چنین شرایطی، پژوهشی موضوع ضروری است. هدف این پژوهش، شناسایی مرتبط فرآیندهای طرح ادعا رویه مواجهه چالش‌ها راستا، لوایح ادعایی ارزیابی شدند. روش پژوهش به‌صورت کمّی ـ کیفی مشتمل بررسی...

This paper overviews the recent advances in flux-adjustable permanent magnet (PM) machines for traction applications. The PM benefit from synergies of high torque density and efficiency conventional as well controllable air-gap field wound-field machines, which are attractive applications requiring enhanced capabilities speed regulation uncontrolled voltage mitigation. In general, three solutio...

This paper starts with the characteristics and advantages of microwaves processing. The shortcomings of fixed frequency, typically at 2.45 GHz were also mentioned. On account of this, the newly developed variable frequency microwave (VFM) fabrication was mentioned and adopted in place of the fixed frequency process. Two cases of fixed frequency microwave processing of materials were described; ...

The IT community has a long history of developing theory to explain when people will change their behaviors to adopt new technology systems. Two current technology adoption theories, the Technology Adoption Model and the Value Frequency Model, draw from different groups of referent theory: Reasons Theories (RTs) and Expectancy Value Theories (EVTs). RTs and EVTs make different assumptions about...
