**Free flow turbines and
their efficiency**** **

Research and Industry Workshop

(**May 06, 2011**, University of Leicester, Leicester, UK).

University Campus, Michael Atiyah Building, MAB119 from
09:30

Participation is Free, Everybody is
Welcome

**Most of
hydraulic turbines** that are presently
used for hydropower generation have been developed for installation in water
dams across streams. However, dams damage the environment and interfere with
fish migration. They also cannot be used for power systems extracting energy
from such huge potential sources as ocean currents or lowgrade rivers. Thus, new
hydraulic turbines are needed that can operate efficiently in free flow without
dams. The principal difference between exploiting high-head and free flow
turbines is that the latter need large flow openings to capture as much water
masses as possible with low velocities and pressure. It was demonstrated that
the efficiency of a free flow turbine is maximal when the resistance is of a
free flow turbine rather small and a large part of the flow (~61 percent) goes
through.

**During this workshop we plan to discuss**
recent development of free flow turbines theory and practice, to compare
various constructions of turbines and to analyse possible efficiency of them.
The talks about related topics from gas and fluid dynamics, energy systems
engineering and mathematical modelling are also welcome

Research
Workshop: **The Enigma of Enceladus:
Observation and Modeling**

**University of Leicester,
UK, June 19-20 2009**

**Organizers:**

**Purpose:**

Purpose of the workshop is to bring together leading experts to present and
discuss recent results from observations and modelling efforts. Topics include Enceladus' history and evolution, surface properties and
processes, heat sources, heat flow, internal structure, chances for liquid
subsurface water, perspectives for formation of life, the gas and dust plume,
as well as the interaction with the Saturnian
environment.

**Research Workshop: Coping with Complexity: Model Reduction and Data Analysis, ****Ambleside, Lake District, UK August 31 – September 4, 2009.**

The theme of the
workshop is deliberately broad in scope and aims at promoting an informal
exchange of new ideas and fresh methodological perspectives in the increasingly
important, inherently interdisciplinary areas of model reduction, data
analysis, approximation and visualization in the presence of complexity. The goal of this initiative is to assemble a group of
people with a wide variety of expertise reflecting the thematically
interdisciplinary nature of the workshop, to organize a series of presentations
and to encourage fruitful discussions in an informal and casual format, thus
circumventing some of the “language barriers” often unnecessarily experienced
by researchers representing different disciplines.

**The
broad thematic structure** of the workshop is organized around the following list of
topics:

1) **Theoretical Approaches**
(deterministic and stochastic): Invariant manifolds, inertial manifolds,
perturbation theory, approximation theory, normal form theory

2) **Computational and Algorithmic Approaches**: Legacy codes and timesteppers,
numerical computation of invariant manifolds, invariant grids, coarse-graining approaches

3) **Data analysis and approximation techniques: **Principal manifolds, dimension reduction
methods, data visualization approaches and their applications.

4) **Fields of Applications**:
Non-equilibrium statistical mechanics, kinetic theory, hydrodynamics and
mechanics of continuous media, (bio)chemical kinetics,
bioinformatics, particulate systems, nonlinear dynamics, nonlinear control.

Research
workshop: **Mathematics of Model
Reduction**, University of Leicester, Leicester, UK August 28 to August 30,
2007.

The workshop is designed in a
manner that aims at the development of a fruitful dialogue amongst the
participants, as well as an informal exchange of new ideas, fresh
methodological perspectives and novel approaches to the increasingly important
problem of Model Reduction that transcends the traditional boundaries of the
main fields in contemporary science and engineering.

Research Workshop: **Lattice Boltzmann at all-scales: from turbulence to DNA translocation**,
Centre for Mathematical Modelling, 15 November 2006, 10:00-16:30, University of
Leicester, Leicester, UK

The lattice Boltzmann (LB)
method was developed nearly two decades ago as an alternative strategy for the
numerical solution of the Navier-Stokes equations of
fluid dynamics. By and large, this task has met with significant success, to
the point that, as of today, LB is routinely used for the numerical
investigation of a wide range of macroscopic flows, from multiphase flows in
porous media, to fully-developed turbulent flows in complex geometries.

Distinguished Lecture: **Lattice Boltzmann at all-scales: from
turbulence to DNA translocation**; Sauro Succi. 15 November 2006, 17:00,
Lecture Theatre 1,

In this Lecture, after a
brief review of the basic ideas behind the LB theory, we shall discuss these
ongoing developments, and present some very recent applications to micro and nanofluidics, such as drag reduction via superhydrophobicity and hydrodynamic effects on DNA
translocation.

The problems of ** Large
Data Sets analysis and visualisation, model reduction and the struggle with
complexity of data sets** are important for many areas of human activity.
There exist many scientific and engineering communities that attack these
problems from their own sides, and now special efforts are needed to organize
communication between these groups, to support exchange of ideas and technology
transfer among them. Heuristic algorithms and seminal ideas come from all
application fields and from mathematics also, and mathematics has a special
responsibility to find a solid basis for heuristics, to transform ideas into
exact knowledge, and to transfer the resulting ideal technology to all the
participants of the struggle with complexity.

The workshop ** “Principal
manifolds for data cartography and dimension reduction,”** was focused on
modern theory and methodology of geometric data analysis and model reduction.
Mathematicians, engineers, software developers and advanced users form
different areas of applications will attend this workshop. The Proceeding volume is
temporarily available online.

Research
workshop: **Geometry
of Genome: **Visualization of Structures Hidden in Genomic Sequences.

The post-genomic era is characterized
by the knowledge of hundreds of completed genomic sequences. Analysis of these
sequences shows that there are common principles of organization of sequence
information. Some of the most powerful methods available for
understanding these principles are based on the geometric representation of genome features. That is, one can study properties of
genomic sequences by representing them in multidimensional spaces defined by
their local properties. In most cases these representations appear to be structured
and organized in a complex hierarchical way. Methods from a variety of scientific
disciplines, such as dimensional reduction and
data visualization, as well as methods dealing with the geometry of
multidimensional spaces help to detect and analyze the structures. The geometric representation is also an important tool for data mining.
