Ahead of the multiplication of specialized applications, needs for application composition increase. Each application can be described by a pair of a visible part –the User Interface (UI) –and a hidden part –the tasks and the Functional Core (FC). Few works address the problem of application composition by handling both visible and hidden parts at the same time. Our proposition described in thi...

The success of component-based development has been impeded by interoperability concerns, including component model, semantic, syntactic, design and platform incompatibilities, that often come into play when composing two or more independently developed components. In this paper we propose a CoCo composition model that elevates compositions to first class citizenship status. The model defines a...

In general, the objective of distillation control is to maintain the desired products quality. In this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. These methods are: a) Composition control using measured composition directly. This method sufferes from large sampling delay of measuring de...

in pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...

a comprehensive study on the chemical composition of rainwater was carried out in obuasi, a gold mining town in ghana. rainwater samples were analyzed for major ions (ca2+,mg2+, k+, na+, nh4+, cl-, no3- and so4 2-) and trace metals (fe, al, zn, pb, cr, and cd). the rainwater was typically acidic with a mean ph of 4.76±0.47, which ranged from 4.0 to 5.6. the low ph found in the water suggests t...

low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. this study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. in order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...
