"The flowering part, it looks like someone is sticking their tongue out" (a subject's description of Arethusa bulbosa, see Figure 1). The mechanisms that people use in natural settings to describe objects to one another can be used to inform the design of image retrieval and museum systems. The image retrieval problem may be recast as an object description problem where the images are of object...

Microwave diplexers are often designed iteratively via manual channel-by-channel or resonator-by-resonator local optimization procedures due to high dimensionality in design variables and the complexity of structures. A one-off automated diplexer method is yet be developed. To achieve this, other than improved optimizers, an effective objective function (OF) critical allow optimizers find desir...

a new method was introduced for frothing characterization of flotation frothers. method uses water recovery to develop a new frothability index named water recovery index (wri). new index was determined for some commercial frothers and results were compared with dynamic frothability index (dfi). results showed that water recovery index values follow the order of a-65 13016 s/mol > df-250 6292.4...

Completely regular pseudo-compact spaces have been characterized in several ways. E. Hewitt [6, pp. 68-70] has given one characterization in terms of the Stone-Cech compactification and another in terms of the zero sets of continuous functions. J. Colmez [2; no proofs included] and I. Glicksberg [4] have obtained characterizations by means of a convergence property for sequences of continuous f...
