In the present work, effect of von Karman geometric nonlinearity on the vibration characteristics of a Y-shaped single walled carbon nanotube (Y-SWCNT) conveying viscose fluid is investigated based on Euler Bernoulli beam (EBB) model. The Y-SWCNT is also subjected to a longitudinal magnetic field which produces Lorentz force in transverse direction. In order to consider the small scale effects,...

the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...

Background: The Covid-19 Pandemic has had a lot of impacts on society and students from various generations. Generations are a group of people who have the same age, traits, and experiences. Not all generations can overcome the impact caused by the pandemic on themselves, which is the cause of various problems in each generation starting from habits, behaviors, and stress. Generations Z and Y a...

At eighty-two million people, Generation Y (18-31) is the largest generation since the Baby Boomers, spending $200 billion yearly. Little past research investigates the web preferences of Generation Y, although some oblique studies have been conducted. This study extends past research by looking specifically at the web design preferences of this important age group. Data is collected through su...

AMBAR es un proyecto que busca el desarrollo de un Sistema Generador de AMBientes de Enseñanza-ApRendizaje Constructivistas basados en Objetos de Aprendizaje (OA). Los ambientes generados por AMBAR deben cumplir con atributos como la interoperabilidad, reusabilidad, accesibilidad y escalabilidad, y esto solo se logra vinculándolos a estándares. En este sentido, se encuentra el IMS Learning Desi...

In practice, laterally loaded piles are most often analysed using a ‘beam-on-non-linear-Winklerfoundation’ approach, whereby the soil–structure interaction is modelled by means of p–y curves. Although well-calibrated p–y curves exist for non-liquefied soils (e.g. soft clay and sand), the profession still lacks reliable p–y curves for liquefied soils. In fact, the latter should be consistent wit...

surface and small scale effects on free transverse vibration of a single-walled carbon nanotube (swcnt) fitted with y-junction at downstream end conveying viscose fluid is investigated in this article based on euler-bernoulli beam (ebb) model. nonlocal elasticity theory is employed to consider small scale effects due to its simplicity and efficiency. the energy method and hamilton’s principle a...

Dual M-Z interferometer is the sensitive element of three-component acceleration seismic geophone, while Y branch waveguide is the basic optical components composed of dual M-Z interferometer, so the design of Y branch waveguide directly affects the performance of threecomponent acceleration seismic geophone. Firstly, branch waveguide and S-shaped bent waveguide are introduced, and symmetrical ...

Purpose A new method for the design of experiments (DOE) or sampling technique is proposed, using a distance weight function and the k-means theory. The radial basis function neural network metamodelling approach is used to evaluate the performance of the proposed DOE by using an n-degree of test function, applied to the complex nonlinear problem of spatial distribution of air pollutants. A com...
