Dreaming of Metaheuristics One of the scientist key policy is always to refer to people who did the first work (as it is pointed out by the "hard blogging scientists" manifest). It is due to the fact that researchers want to share free science with everybody (at least at little cost), and that recognition is a form of remuneration (in a similar way, Eric S. Raymond explain such mechanism for hackers, in his essay "The Cathedral and the Bazaar"). Recently is increasing a (rather small, but interesting) controversy about the authorship of the Ant Colony Optimization (ACO) idea. The "orthodox" seminal paper about ACO is a technical report, written by Dorigo, Maniezzo and Colorni, submitted in 1991. As technical report are not a rigourous publication, perhaps a more pertinent citation would be the corresponding paper published in the proceedings of the First European Conference on Artificial Life, in 1992, or the Dorigo's PhD thesis, completed in 1991.
Body force implementation without lattice effects Hello Tim Thank you for helping me once more :) You say that my indexes are mistaken and that instead of k it should be j. For me the indexes that you said make more sense than those I wrote however, reporting to Guo's article, the way to find a proper expression for F(i) is based on a power series expansion of the kind : F(i)=w(i)*[A+B(j)*e(i,j)/cs^2+C(j,k)*e(i,j)*e(i,k)/(2*cs^4)-C(j,k)/(2*cs^2)] Create a mysql database, tables and insert data How do I create a MySQL database, tables, and insert (store) data into newly created tables? MySQL is a free and open source database management system. You need to use sql commands to create database. You also need to login as mysql root user account.
Invisible Web: What it is, Why it exists, How to find it, and Its inherent ambiguity What is the "Invisible Web", a.k.a. the "Deep Web"? The "visible web" is what you can find using general web search engines. It's also what you see in almost all subject directories. The "invisible web" is what you cannot find using these types of tools. The first version of this web page was written in 2000, when this topic was new and baffling to many web searchers.
Nancy White Sep 11 2007 Communications, planning, and connected solutions for a changing world Telephone: (206) 517-4754 Location: Seattle, Washington, USA Full Circle Associates is me, Nancy White, plus my network of professionals who provide services individually and collectively for clients in the community, non-profit and business sectors. Dreaming of Metaheuristics Note that descriptions are picked up from the web sites of the projects. As one can see, most of these softwares are designed for evolutionnary algorithms, but I recommend you to try out some of the generic frameworks, because "genetic" algorithms are not always the best choice for solving an optimization problem, despite their wide spread. Here are the frameworks I would recommend. These frameworks are free softwares, you can use, look at the code, modify it and redistribute it (precious qualities for frameworks). I would also recommend C or C++, which permits to implement fast programs, while using object oriented programming. C++ compilers are also available for a large choice of plateforms (with a special distinction for GCC, which is free software).
technical papers on lattice Bolzmann, vehicle design, wind noise sourcing and aeroacoustic analysis, engine top tank temperature and cooling airflow thermal simulations and more Exa provides software products and services for simulation-driven design. Leading manufacturers use Exa’s fluid flow, heat transfer, and acoustic simulation solutions to optimize the performance of their products, reduce product development costs, and improve the efficiency of their design and engineering processes. Simulation-driven design enables engineers to predict product performance early in the design process, reducing late-stage design changes and reducing or eliminating expensive physical prototypes and tests.
Tools:Memory Imaging The physical memory of computers can be imaged and analyzed using a variety of tools. Because the procedure for accessing physical memory varies between operating systems, these tools are listed by operating system. Once memory has been imaged, it is subjected to memory analysis to ascertain the state of the system, extract artifacts, and so on. One of the most vexing problems for memory imaging is verifying that the image has been created correctly.
Visualizing citations in research literature From Autodesk Research, Citeology is an interactive that visualizes connections in academic research via paper citations: The names of each of the 3,502 papers published at the CHI and UIST Human Computer Interaction (HCI) conferences between 1982 and 2010 are listed by year and sorted with the most cited papers in the middle. In total, 11,699 citations were made from one article to another within this collection. Connectivism & Connective Knowledge Week 9 is a conference week, focusing on Net Pedagogy. This will be a great opportunity to reflect on how social networks and networked technology impact how we teach and learn. We’ve lined up five excellent speakers for the week:
Neuroevolution of augmenting topologies NeuroEvolution of Augmenting Topologies (NEAT) is a genetic algorithm for the generation of evolving artificial neural networks (a neuroevolution technique) developed by Ken Stanley in 2002 while at The University of Texas at Austin. It alters both the weighting parameters and structures of networks, attempting to find a balance between the fitness of evolved solutions and their diversity. It is based on applying three key techniques: tracking genes with history markers to allow crossover among topologies, applying speciation (the evolution of species) to preserve innovations, and developing topologies incrementally from simple initial structures ("complexifying"). Performance On simple control tasks, the NEAT algorithm often arrives at effective networks more quickly than other contemporary neuro-evolutionary techniques and reinforcement learning methods.

Cambridge many-core.group - Lattice Boltzmann demo Graham Pullan Vortex shedding behind a "cylinder". Top CPU (C), bottom GPU (CUDA) Introduction The lattice Boltzmann method is a simple way of calculating fluid flow (particularly if the flow is incompressible and the problem of interest is at a low Reynolds number). More details of the method can be found at lbmethod.org.
To create a MySQL database and set privileges to a user MySQL is a widely spread SQL database management system mainly used on LAMP (Linux/Apache/MySQL/PHP) projects. In order to be able to use a database, one needs to create: a new database, give access permission to the database server to a database user and finally grant all right to that specific database to this user. This tutorial will explain how to create a new database and give a user the appropriate grant permissions. For the purpose of this tutorial, I will explain how to create a database and user for the music player Amarok. In order to index its music collection, Amarok quand use a mysql backend. The requirement for this set up is to have access to a database.
