Subsurface Characterization Using Geophysical and Geohydrological Data Fusion

Metin Ozbek, James Ross, George Pinder & Metin Ozbek
We are introducing a novel technology applicable to the robust interpretation of the spatial distribution of hydraulic conductivity in heterogenous formations. The evidence theory approach is based on a combination of directly measured hydrogeological and geophysical data together with expert opinion. The approach first utilizes fuzzy-set based approximate reasoning to quantify subjective expert opinion, especially when data are scarce, to create a fuzzy prior characterization of the hydraulic conductivity field. Subjective information includes, but is...

Effective anisotropy tensor for the numerical solution of heterogenous porous media flow problems

Gian Paolo Leonardi, Fabio Paronetto, Mario Putti & Gian Paolo Leonardi
The numerical solution of strongly heterogeneous and anisotropic porous media flow equations often requires the definition of discrete interfacial average fluxes. Standard methods, such as Integrated Finite Differences (IFD) or Finite Volumes (FV), start from the definition of an average solution gradient and calculate the interface fluxes by means of appropriate averages of the conductivity tensor K. For a scalar K, the harmonic average is correct in the sense that it returns the same flux...

Work related musculoskeletal disorders among nurses

Deepak SHARAN, Mathankumar MOHANDOSS, Rameshkumar RANGANATHAN, Jerrish JOSE & Joshua Samuel RAJKUMAR
A systematic review was conducted to study the current literature related to work related musculoskeletal disorders in nurses. A review was done using MEDLINE by the keywords “nurses”, “risk factors”, and “musculoskeletal disorders”. All the articles were reviewed by three reviewers based on the EPOC criteria and studies which were not adequate and inappropriate were excluded. Study design, type of data collection, assessment tools and outcomes obtained in the respective study were noted. Nurses were...

Linear Wind Power Plant

Mark Roenberg Hansen, Sine Smed W. Sørensen & Edmond Müller
Wind energy is converted into electric power via wing sails moving on rails. A linear generator/motor is split between the rail and carriage, where the linear stator is integrated in the rail track. Each carriage contains a part of the linear rotor. The acceleration/deceleration of each carriage is controlled by adjusting the electrical power input/output of the converters related to the carriage.

ReaxFF modelling of enzyme catalysis

Peter Bjerre Jensen, Peter Fristup & Hans J. Aa. Jensen
Modelling of chemical systems has many advantages compared to what people normally think chemistry is (that is synthesis). Computers can model complicated chemical reactions much faster, than the time an ordinary experiment would take. In this project the so-called reactive force field, ReaxFF, which is capable describing chemical reactivity orders of magnitude faster than the current state-of-the-art methods, is developed. The method could be used to study chemical reactions and improve them thereby lowering the...

Developing Open Source System Expertise in Europe

Mads Nyborg, Finn Gustafsson & Jørgen Christensen
Developing Open Source System Expertise in Europe is an Erasmus intensive programme (IP). The aim of this IP is to exchange knowledge of and experience in local methods and techniques in the field of open source software knowledge in ICT by engaging a group of European students and lecturers in a joint, explorative investigation of contemporary methods of open source software systems. In this paper we describe our experience in setting up a design-build project...

Student engineering teams develop a 3 m scale model inspired after the NASA-Boeing X48-B blended wing body to use as a test bed for advanced technical studies. The design concept implements a novel hybrid gas/biodiesel-electric power train as a green aircraft technology. The Hyperion aircraft will serve as a test-bed for research and development in the following focus areas: aerodynamics, structures and materials, weights and mass properties, handling and control, flight mechanics, and efficiency improvements...

Making technology for production of bioethanol from lignocellulose economically feasible: plant wide simulations

Dalia Cepulyte, Sin, Asst. Prof. Gürkan, Morales Rodrigues, Postdoc Dr. Ricardo, Meyer, Prof. Anne & V Gernaey, Assoc. Prof. Krist
The development of an optimal process technology for second generation bioethanol production (biological route) is still one of the major challenges facing the green production of biofuels. It is a huge technology and engineering challenge from the process design and operation point of view. This course takes on this challenge and will search for the optimization of one conventional bioethanol process flowsheet. The course will use dynamic plant model simulations to generate innovative solutions. The...

Pore-scale simulation of dispersion and reaction along a transverse mixing zone in two-dimensional heterogeneous porous medium composed of randomly- sized, shaped and distributed circular and elliptical cylinders

Ram Acharya, Albert Valocchi, Thomas Willingham, Charles Werth & Ram Acharya
Several studies have demonstrated the important role played by transverse dispersion along the lateral fringe of chemical plumes in porous media. For example, the success of natural and engineered in-situ remediation relies on the transverse mixing of reactive chemicals or nutrients. Field, laboratory, and theoretical studies have also demonstrated that the length scale of transverse mixing zones can be very small, often on the order of millimeters or centimeters. In order to study dispersion, mixing...

Taking into account air pressure variations in subsoil air-water

Jerome Jaffre, Estelle Marchand, François Clement, Jean Roberts & Jerome Jaffre
The Richards equation is widely used in hydrogeology for modelling flow in an unsaturated porous media. It is a simplified version of the general two-phase model, which assumes that air pressure is invariant. To fully take into account the presence of air which may be trapped in the subsoil, it will be necessary to consider the non simplified two-phase flow. The aim of this work is to examine different numerical methods for trading these two...
