Modeling of Active Infrared Thermography for Defect Detection in Concrete Structures

S. Carcangiu[1], B. Cannas[1], G. Concu[2], N. Trulli[3]
[1]Department of Electric and Electronic Engineering, University of Cagliari, Cagliari, Italy
[2]Department of Civil Engineering, Environmental and Architecture, University of Cagliari, Cagliari, Italy
[3]Department of Architecture and Planning, University of Sassari, Alghero, Italy

An experimental program has been developed, with the purpose of evaluating the reliability in building diagnosis and characterization of an integrated analysis of several parameters related to heat transfer process through the building material. The Infrared Thermography Technique (IRT) ... En savoir plus

A Coupled Analysis of Heat and Moisture Transfer in Soils

E. Evgin, J. Infante Sedano, and Z. Fu
University of Ottawa
Ottawa, ON
Canada

This paper is a part of a study on energy piles for heating and cooling of buildings. Energy piles are used for two reasons: (1) to transfer structural loads to foundation soils, and (2) to transfer heat from foundation soils to the building for space heating in winter time and for ...

Light Scattering by Subwavelength Arrays of Silicon Nanowires

M.l. Urbaneja Torres, A. Manolescu
School of Science and Engineering, Reykjavík University, Reykjavík, Iceland

The study of light scattering by optically resonant nanostructures is a field of growing interest as a result of the rapid progress in nanophotonics in the last decade. Contrary to their plasmonic counterparts, high-index dielectric structures exhibit low optical losses and different ... En savoir plus

Heat and Moisture Transport in Wooden Bearings of Monumental Buildings

H. Schellen [1], M. Spierings [2], J. van Schijndel [3],
[1] Eindhoven University of Technology, The Netherlands
[2] DPA Cauberg-Huygen, The Netherlands
[3] ASML, The Netherlands

Currently insulation has been and will in future be applied to many buildings. This proves to be a challenge for monumental or old buildings. Mostly insulation has to be applied at the interior side of a building. That is why hygro-thermal bridges are inevitable. A wooden beam end beared ... En savoir plus

The Use of Finite Element Analysis in the Design of Oil-Water Separators

M. E. Wanas [1], Y. M. Elshazly [1], D. A. ElGayar [1],
[1] Chemical Engineering Department, Faculty of Engineering, University of Alexandria, Alexandria, Egypt

Oil-water separators play an important role in several industries as well as in waste water treatment. However, no basic principles have been set to guarantee the designed separators would work according to the desired efficiency due to the effect various factors. Both time and money ...

Optimization of Dynamic Embedded, Water Based Surface Heat (and Cold) Emitting System for Buildings

S. Thomas[1], P.Y. Franck[1], and P. André[1]
[1]Department of Sciences and Environmental Management, University of Liège, Arlon, Belgium

This paper presents the heat flow model and the experimental test bench developed to optimize a new kind of heating floor. In the first part of the text is described the new kind of high reactivity emitting device for building heating and cooling. The second part illustrates the ... En savoir plus

Calculation of Inductance of Sparsely Wound Toroidal Coils

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corporation, Hauppauge, NY, USA

Analytical methods used for inductance calculation of toroidal coils yield large errors in the case of coils sparsely wound on low permeability cores. Numerical field calculations can provide “exact” figures. We have outlined several simulation methods. Simplifications, assumptions, and ... En savoir plus

Magnetic Prospecting Modeling of Seamount with COMSOL Multiphysics

G. Ha, S.-S. Kim [1]
[1] Chungnam National University, Daejon, Korea

In general, seamount magnetic modeling assumes uniform magnetization for the entire construct. The following geologic obervations are often not considered: 1. The internal structure composed of multiple volcanic layers, and 2. Remanent magnetization gained during the magnetic polarity ... En savoir plus

The SoftPad: a soft layer for adding compliance to the environment in robotic manipulation tasks

Maria Pozzi¹, Chiara Gaudeni¹, Zubair Iqbal¹, Domenico Prattichizzo¹, Monica Malvezzi¹
¹University of Siene, Department of Information Engineering and Mathematics, Siene, Italy

Soft robotics is an emerging research field that is rapidly expanding as soft robots are adaptable, reliable, and intrinsically safe. While the behavior of robots composed of rigid links, joints, and actuators can be easily described with classical mechanics modeling methods, modeling ... En savoir plus

Safe Cracking: Monte Carlo Nonlinear Coupled Analysis of Nuclear Reactor Bricks

M. Pogson[1], A. Bond[1], P. Robinson[1]
[1]Quintessa, United Kingdom

Advanced Gas Cooled Reactors (AGRs), owned and operated by EDF Energy, generate around 15% of electrical power in the UK. As AGRs approach their end of life, cracking is liable to occur in the graphite bricks which make up a major part of the reactor core. Safety cases to justify ... En savoir plus
