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...

today, along with enhancement of social well-being andeconomic development, demand for transportation is growing increasingly.many countries are seeking for providing transportation servicesat a reasonable price. therefore, optimization of carrying goods on nationalor international roads is highly important in terms of costs andtransportation indicator, so that the goods are shipped at minimumc...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

BACKGROUND Dengue is an increasingly important public health problem in most Latin American countries and more cost-effective ways of reducing dengue vector densities to prevent transmission are in demand by vector control programs. This multi-centre study attempted to identify key factors associated with vector breeding and development as a basis for improving targeted intervention strategies....

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...

 We introduce a dynamic and stochastic transportation problem consisting of two subproblems. For parcel transportation in hub-and-spoke networks, swap containers are used to carry out hub-to-hub shipments. This constitutes a pickup and delivery problem on the operational level. On the tactical level, empty swap containers are balanced over the hub-network in order to match the stochastic deman...
