Consider the small area estimation when positive area-level data like income, revenue, harvests or production are available. Although a conventional method is the logtransformed Fay-Herriot model, the log-transformation is not necessarily appropriate. Another popular method is the Box-Cox transformation, but it has drawbacks that the maximum likelihood estimator (ML) of the transformation param...

Within the past a few years, transformation optics has emerged as a new research area, since it provides a general methodology and design tool for manipulating electromagnetic waves in a prescribed manner. Using transformation optics, researchers have demonstrated a host of striking phenomena and devices; many of which were only thought possible in science fiction. In this paper, we review the ...

INTRODUCTION The semantic interoperability of electronic healthcare records (EHRs) systems is a major challenge in the medical informatics area. International initiatives pursue the use of semantically interoperable clinical models, and ontologies have frequently been used in semantic interoperability efforts. The objective of this paper is to propose a generic, ontology-based, flexible approac...

Social networks and other web 2.0 platforms use huge amounts of data to offer new services to customers. Often this data can be expressed as huge graphs and thus could be seen as a potential new application field for model transformations. However, this application area requires that model transformation tools scale to models with millions of objects. This transformation case targets this appli...

Recently, a novel transformation technique for Datalog programs , called the branching transformation, was introduced by the authors. In this paper we propose a signiicant extension of the branching transformation which we believe opens-up a promising new direction of research in the area of value-propagating Datalog optimizations. One of the novel characteristics of the proposed approach is th...

Not least due to the widespread use of meta modeling concepts, model transformation techniques have reached a certain level of maturity (Czarnecki and Helsen, 2006). Nevertheless, defining transformations in some application areas in our case business process modeling is still a challenge because current transformation languages provide general solutions but do not support issues specific to a ...

The prevention and correct management of natural disaster event sequences play a key role in saving human lives. The availability of embedded and mobile smart computing systems opens new roads for the management of land and infrastructures by civil protection operators. To date, research has explored the use of social networks for the management of disasters connected to meteorological/hydrogeo...

Accurate registration of airborne images is challenging because complex local geometric distortions are often involved in image acquisition. In this paper, we propose a solution to this registration problem in two parts. First, we present an area-based method to extract sufficient numbers of well-located control points, and second, we use the extracted control points with local transformation m...

bainitic transformation at low transformation temperatures leads to a microstructure involving fine plates of bainitic ferrite and thin films of retained austenite. this microstructure has shown ultimate tensile strength of about 2.2 gpa, noticeable uniform elongation in the range of 5 to 30%, hardness values of about 600 to 670 hv and impact toughness in the range of 30 to 40 mpa m1/2. with ca...
