In this paper, the effects of container size on the porosity of random loose packing of mono size particles have been investigated using an Event Dynamics (ED) based model. Simultaneous effects of square container walls on particles packing and their order are also investigated. Our simulation results indicate higher container size will increase the total packing factor and high density regions...

this study analyses the concept of cost functions for semi-automated straddle carrier (sc), rubber tyred gantry (rtg) and automated rail mounted gantry (rmg) container yard operating cranes. it develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

introduction: functional constipation is one of the most common gastrointestinal symptoms which could affect patients’ quality of life. the colonic transit time test could be used for determining functional constipation subtypes. the aim of our study was to determine the abnormalities of the subtypes of functional constipation using ctt. methods and materials: this cross-sectional study was per...

It is argued that the association of any two random elements with positive joint probability density function is characterized by its odds ratio function. The impact of this fundamental result is explored in two applications. In Bayesian analyses it is the association between an observable random variable and a random parameter that is of primary interest. In multivariate analysis it is the ass...

We begin with defining the ubiquitous concept of a vector space and several properties associated with them, as well as mathematical operations defined on them. The concept of a vector space is, in general, defined over an arbitrary field of scalars. However, we shall restrict ourselves to real vector spaces, i.e. those defined over the field of reals. Definition 2.1 (Vector Space). A real vect...

Central pseudoscalar production in pp scattering is suppressed at small values of Q ⊥ , where Q is defined as the difference between the momenta transferred from the two protons. Such a behaviour is expected if the production occurs through the fusion of two vectors. Photon exchange could provide the dominant contribution here, but we argue that an extension of the experiment could probe the gl...

Nowadays, traffic management policy in metropolitans is focused on increasing the share of public transit. The limitation of supply and slowing growth of road infrastructures have provided congestion for users who choose personal cars. Therefore, applying demand management policies which decrease the utility of personal cars and increase the tendency to public transit can be very important. Con...

The present study deals with high-speed ultrasonic tomography (UT) as a powerful tool to characterize the behavior of multiphase flows. A major goal work is improve temporal resolution for detection transit flow structures and time-dependent phenomena such incidence rising gas bubbles. special transducer wide divergence angle 110° vertical height measurement volume approx. 4 mm was developed te...
