Evaluation of Inverse Modeling Techniques for Pinpointing Water Leakages at Building Constructions

Determination of Hygrothermal Properties for Building Materials using Inverse Modeling Techniques

The paper presents the development of a method that determines building material and surface properties using relative simple and low-budget experiments, with the following conditions: (I) Constrained: the material is located in building constructions and only non destructive measurements are allowed. (II) Unconstrained: the material if is freely available for optimal testing. The latter compre...

An Evaluation of Computational Imaging Techniques for Heterogeneous Inverse Scattering

Inferring internal scattering parameters for general, heterogeneous materials, remains a challenging inverse problem. Its difficulty arises from the complex way in which scattering materials interact with light, as well as the very high dimensionality of the material space implied by heterogeneity. The recent emergence of diverse computational imaging techniques, together with the widespread av...

Monitoring of Water Leakages from Pipes through Geophysical Imaging Methods

conditional copula-garch methods for value at risk of portfolio: the case of tehran stock exchange market

ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...

Constructions for Modeling Product Structure

This paper identifies constructions needed for modeling product structure, shows which ones can be represented in OWL2 and suggests extensions for those that do not have OWL2 representations. A simplified mobile robot specification is formalized as a Knowledge Base (KB) in an extended logic. A KB is constructed from a signature of types (classes), typed properties, and typed variables and opera...
