WORKING WITH SPATIO-TEMPORAL DATA TYPE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Several aspects of spatiotemporal databases have been explored in past decades, ranging from basic data structure to query processing and indexing. But today, operational temporal GIS does not exist.

A Software Development Model for the Automatic Generation of Classes
CLEI Electronic Journal, 2018 In this paper it is presented a software development model based on transformations that allows to derive, in an automatic way, classes in object-oriented programming languages (Ada 95, C++, Eiffel and Java) starting from formal specifications.

Evidence-Based Dentistry, 2007 In most, if not all, studies we collect data to obtain information about an area of research in which we have an interest. For example, we might want to know the level of dental caries in our area. In order to discover this we might need to observe a number of different variables, which could include, age, sex, number of teeth, cavities, fillings ...

Iteratively regularized Newton-type methods for general data misfit functionals and applications to Poisson data [PDF]
, 2012 We study Newton type methods for inverse problems described by nonlinear operator equations $F(u)=g$ in Banach spaces where the Newton equations $F'(u_n;u_{n+1}-u_n) = g-F(u_n)$ are regularized variationally using a general data misfit functional and a ...
