The growth kinetics of calcite crystals are studied in a batch-fluidized-bed crystallizer, which is maintained at a constant pH. The growth experiments are conducted in the metastable region explored as part of this research. The crystal growth rates are e®aluated from the consumption rates of calcium ions, using the cured natural calcite or silica sand as seeding materials. Se®eral operation ®...

A method for decompose the triangulated surface into quadrilateral patches using Morse theory and Spectral mesh analysis is proposed. The quadrilat-eral regions extracted are then regularized by means of geodesic curves and fitted using a B-splines creating a new grid on which NURBS surfaces can be fitted.

We introduce and study strongly truthful mechanisms and their applications. We usestrongly truthful mechanisms as a tool for implementation in undominated strategies for sev-eral problems, including the design of externality resistant auctions and a variant of multi-dimensional scheduling.

Analytical reliability modeling is a promising method for predicting the reliability of di erent architectural variants and to perform trade o studies at design time However generating a computationally tractable analytic model implies in gen eral an abstraction and idealization of the real system Construction of such a tractable model is not an exact science and as such it depends on the model...

This paper presents sev eral non-linear models adjusted in order to capture the dynamics of a gypsum kiln. The behavior of this kind of processes is a ected by nonlinear e ects caused by theexistence of disturbances and the coupling among some variables. The use of second order Volterra and Hammerstein models as appropriate solutions to describe the process dynamics is analyzed. A thorough stud...

nternational tobacco smuggling remains an important concern for governments, manufactur-ers and health experts alike. While often linked to other forms of illegal activities, it also directly impacts govern-ment tax policies. Knowledge factors that contribute illicit trade the existence smug-gling routes is strongly hampered by lack reliable data on bilateral flows tobacco. Therefore, recon-str...

This chapter presents a methodology for diagnosis of pigmented skin lesions using convolutional neural networks. The architecture is based on convolu-tional networks and it evaluated new CNN models as well re-trained modification pre-existing were used. experi-mental results showed that pre-trained big datasets gen-eral purpose image classification when in order to identify le-sion types offer ...

The CAVE project (CAller VEri cation in Banking and Telecommunications) was a 2 year project supported by the Language Engineering Sector of the Telematics Applications Programme of the European Union, and for the Swiss partners, by the O ce F ed eral de l'Education et de la Science (Bundesamt f ur Bildung und Wissenschaft). The partners were Dutch PTT Telecom, KUN, KTH, ENST, UBILAB, IDIAP, V...

This paper addresses the dynamics and control of di rect drive robots with positive joint torque feedback We analytically derive the system dynamics in closed form Even though it is coupled and nonlinear in gen eral it is substantially simpler than the robot link dy namics We also derive conditions on the robot con g uration which result in linear dynamics Motion con trol laws for both cases ar...
