Velarde" Date: Thu, 21 Mar 2002 17:08:03 +0100 (CET) NONLINEAR DYNAMICS OF SURFACE-TENSION-DRIVEN INSTABILITIES authors: P. COLINET, J. C. LEGROS & M. G. VELARDE WILEY-VCH, 2001 (ISBN 3-527-40291-8) 512 pp. A century after Henri Benard discovered cellular convective structures, thermal convection in fluid layers still remains a central subject in nonlinear physics. This book provides readers with a progressive and complete insight into this vast field, describing as it does a number of "first principle" analyses of realistic set-ups, including several physicochemical processes at interfaces. Nonetheless, much emphasis is placed on the generality of the results and methods used, by way of the detailed derivation and analysis of a number of generic nonlinear equations known to hold in many physical systems, even outside the realm of fluid mechanics. INTERFACIAL PHENOMENA AND CONVECTION authors: A. A. NEPOMNYASHCHY, M. G. VELARDE & P. COLINET CHAPMAN AND HALL/CRC/PITMAN SERIES #124, 2002 (ISBN 1-58488-256-5) 365 pp. It is only in the past two or three decades that researchers have performed suitable, clear-cut experiments involving interfacial phanomena, and the stage is now set for a virtual explosion of the field. This book is a timely one as it is a selfcontained monograph that examines a rich variety of phenomena in which interfaces play a crucial role. From a unified perspective that embraces physical chemistry, fluid mechanics, and applied mathematics, the authors study recent developments related to the Marangoni effect, hence phenomena involving surface tension gradients as driving forces, including patterned and disordered convection, oscillatory/wavy phenomena and dissipative solitons, falling films, drop migration, and liquid spreading. SYNERGETIC PHENOMENA IN ACTIVE LATTICES (PATTERNS, WAVES, SOLITONS, CHAOS) authors: V.I. NEKORKIN & M.G. VELARDE SPRINGER-VERLAG, SYNERGETIC SERIES, 2002 (ISBN 3-540-42715-5) 357 pp. Within nonlinear spatio-temporal dynamics, active lattice systems are of relevance to the study of multidimensional dynamical systems and the theory of nonlinear waves and dissipative structures of extended systems. In this book, the authors deal with basic concepts and models, with methodologies for studying the existence and stability of motions, understanding the mechanisms of formation of patterns and waves, their propagation and interactions in active lattice systems. Detailed analyses are provided, from a unifying perspective, of the evolution and interactions of dissipative solitons. This is done using a dissipation modified Boussinesq-Korteweg-de Vries equation, a perturbed sine-Gordon equation and evolution equations with Chua's circuits. Treated also with great details are (amplitude, frequency, phase) clustering and synchronization phenomena, control and replication of forms and waves using oscillatory, bistable and excitable units and coupled map lattices, etc. The book emphasizes how much cooperation or competition between order and chaos is crucial for synergetic behavior and evolution. The results described in the book have both inter- and trans-disciplinary features and a fundamental character. It is a textbook for graduate courses in nonlinear sciences, including physics, biopphysics, biomathematics, bioengineering, neurodynamics, electrical and electrocnic engineering, mathematical economics, and computer sciences. ------ Subject: Post-Doctoral Positions in Geomechanics From: Gary Couples Date: Fri, 22 Mar 2002 15:05:40 -0000 The Department of Petroleum Engineering at Heriot-Watt University has obtained industrial funding to support two research positions in the area of geomechanics. The projects are directed by Dr Gary D. Couples. One post (Ref. 63/02/) is focused on the application of simulation tools to address the processes of fault-rock formation, and the evolution of these materials as faulting continues. We will use both continuum and dis-continuum methods, and the goal is to predict the associated changes of porosity, permeability, and capillary entry pressures so as to enable fluid-flow simulations to be performed. Programming skills and topic-related experience are highly desirable. The appointee will interact with other researchers working on this project, including staff at other universities. The second post (Ref. 64/02/) is focused on the deformation of mudrocks, and especially how deformation impacts the capacity of mudrocks to act as hydrocarbon seals. The work will entail both laboratory deformation of mudrocks and analysis of the resulting damage, and may be extended to include geomechanical simulations. The research will interface with (or could be extended to include) flow-simulation tasks at Heriot-Watt, and the appointee will interact with associated research staff at other universities. Further particulars concerning these posts can be obtained at the URL: http://www.pet.hw.ac.uk/jobs/index.html Overviews of the projects that these posts are related to can be found at http://www.pet.hw.ac.uk/staff/pages/couples_g.html To apply, please request an application form at the address below. In addition to returning the application form, and the related information that it requests, you will need to supply a covering letter that explains why you think that you qualify for one of the posts, and a statement of your research interests. If you wish to apply for both posts, it is not necessary to fill out two copies of the application form - but please indicate both reference numbers on the form. For application details, please contact: Personnel Office, Heriot-Watt University Edinburgh EH14 4AS Scotland.

The MARS-3D code simulates the oceanic circulation from shoreline to few hundreds of kilometres offshore. The primitive Navier-Stokes equations are solved under both hydrostatic and Boussinesq asumptions. Based on finite difference discretisation, this code is written in Fortran (norm 77). It presently runs on several platforms (SUN, Linux PC, Compaq cluster, NEC SX5), with shared memory parallelisation using OpenMP library. This post-doctoral position will focus on enhancing the performance of the MARS-3D code on shared and/or distributed memory computers. The work will be divided into two tasks. Task 1 consists in analysing the behaviour of the OpenMP parallel version on a Compaq cluster (a local facility) and on an IBM cluster (Power 4 large nodes, at the remote IDRIS computing center). Enhancement of the performance is expected. This task should make familiar with algorithmic details in computational intensive parts of the code. Task 2 designs and implements a parallel version for distributed and mixed memory architectures, based on the MPI communication library. The high potential of this study for an original scientific achievement lies in the algorithmic processing of the specific physical, hence computational, constraints imposed by coastal hydrodynamics. This position is offered at IFREMER premises in Brest, for a one year duration with a possible 6 month extension. Skills in scientific computing are expected: both a basic knowledge in numerical analysis and an experience of parallel computing with the use of communication libraries MPI and/or OpenMP and the comprehensive knowledge of today's computer architectures. Obviously, notions of oceanography are a bonus.
