abstract = {Using spatial models as a shared common basis of information about the
environment for different kinds of context- aware systems has been a heavily
researched topic in the last years. Thereby the research focused on how to
create, to update, and to merge spatial models so as to enable highly dynamic,
consistent and coherent spatial models at large scale. In this paper however,
we want to concentrate on how context-aware applications could use this
information so as to adapt their behavior according to the situation they are
in. The main idea is to provide the spatial model infrastructure with a
situation recognition component based on generic situation templates. A
situation template is - as part of a much larger situation template library -
an abstract, machine- readable description of a certain basic situation type,
which could be used by different applications to evaluate their situation. In
this paper, different theoretical and practical issues - technical, ethical and
philosophical ones - are discussed important for understanding and developing
situation dependent systems based on situation templates. A basic system design
is presented which allows for the reasoning with uncertain data using an
improved version of a learning algorithm for the automatic adaption of
situation templates. Finally, for supporting the development of adaptive
applications, we present a new situation-aware adaptation concept based on
workflows.},

common approach to stereovision leads to high deviations from the real
positions when it is not possible to synchronize the cameras for tracking
moving objects. Therefore we introduce an object localization in RoboCup
combining the most accurate position information from each camera system. Our
method for a reliable three-dimensional position estimation can be used to
track a flying ball after being kicked by a robot.},

abstract = {The autonomous robotics community is starting to tackle more and more complex
manipulation activities, such as doing household chores, in more and more
realistic operating environments such as human working and living environments.
One of the biggest challenges in such applications is the open-endedness of the
task domains and the enormous amount of knowledge needed to achieve reliable
task success. Luckily almost every robot has access to the World Wide Web, the
world's largest knowledge and information source. While up to now robots have
only made limited use of the web as an information and knowledge source the
opportunities are obvious and manifold. Robots can use search engines such as
Google images, video, or 3D warehouse. They can also ask for the help from
humans using tools such as the Amazon Mechanical Turk. Or, robots could perhaps
form communities to build up huge common knowledge bases, much in the same
spirit as people work on Wikipedia. Or, robots could reproduce the situations
they cannot handle in web games and observe how the players deal with the
situations and what the consequences might be. This workshop aims at bringing
robotics researchers together that investigate the ways that robots can make
good use of the Internet infrastructure. The workshop will provide a
state-of-the-art overview of the field and will offer ample room for discussion
to jointly identify new challenges and opportunities for future research.},

problem. In this paper we describe these difficulties which result from the
combination of very distinct areas. On the one hand, applications from area of
measurement engineering manage sensors that capture data and annotate the data
with technical meta data. On the other hand, context-aware workflows from the
BPM area place high level requirements for the quality of context data that is
derived from the sensor data. Between those two areas exists a gap that has to
be closed by a context management and mediation system, supporting the handling
of Quality of Context (QoC). To achieve this the paper presents an QoC aware
architecture based on an extension of the existing Nexus Platform and a first
approach for matching the workflow requirements with the sensor annotations.},

abstract = {The study of bifurcations in a piecewise-smooth system is quite different from
those occurring in smooth systems. In piecewise-linear systems, which we are
considering in this paper, mainly border collision bifurcations (BCBs) and
contact bifurcations occur. It is classified as border-collision any contact
between an invariant set of a map with the border of its region of definition,
and this may, or may not, produce a bifurcation. The term border-collision
bifurcation was introduced for the first time by Nusse and Yorke in 1992 and is
now widely used in this context (i.e. for piecewise smooth maps). Recently,
these bifurcations have been studied mainly because of their relevant
applications in engineering (electrical and mechanical), and also in economics
and social sciences. In fact, several publications were motivated by models
describing particular circuits or models for the transmission of signals.
Remarkably also before the work by Nusse and Yorke the bifurcations associated
with piecewise smooth maps were studied in some publications (although the
bifurcations were not called border-collision bifurcations). We recall, for
example, the works by Mira (1978) and others. We may also go further back,
citing the work by Leonov in the end of 50th. In his work, Leonov described
several bifurcations, giving a recurrence relation to find the analytic
expressions of families of bifurcations occurring in a one-dimensional
piecewise linear map with one point of discontinuity, which is still mainly
unknown. The object of this work is to give a new interpretation and
improvements of some of his results.},

constructed in such a way that it shows a similar dynamic behavior like a

positive sign derived from the time continuous model of an impact oscillator.
Since the square root part makes analytical studies complicated, the
constructed map serves us as an easy to investigate test system. The stable
periodic dynamics of this piecewise-linear map was found to be organized by a
heretofore unexplained bifurcation structure in an extended region in parameter
space, which superficially resembles period adding. This work explains the
stable periodic behavior of the truncated tent map and the new bifurcation
structure.},

attractors emerge at the boundary between the periodic and the chaotic domain,

abstract = {Symbiotic robotics is a discipline within collective robotics that is concerned
with artificial multi-cellular robot-organisms that define their morphological
structure by aggregation through self-assembling and they are also able to
disaggregate afterwards. This contribution is concerned to the description of
evolutionary and cognitive principles that governs such a symbiotic cycle to
build artificial organisms of different forms and operate with them. The
evolutionary approach starts with a artificial genome, will be continued by the
insertion of different types of regulative cycles, and ends up in an
embryogenetic formed body. Hereby there is differentiation between the genetic
based learning and the fitness based learning. Further there are dominant
differences between multi-cellular organism and structured cooperative
aggregations of swarm members. The cognitive approach is focused on cognitive
maps, on cognitive sensor data fusion and finally to the definition of
information that governs the the process of organism formation and body
survival in a given environment. This more engineering oriented approach is
used to build all HW-components and all kinds of embedded {\^a}operating systems{\^a}
to control and to operate symbiotic robot organisms.},

the hypothesis regarding the self-similarity of the bandcount adding structure.},

abstract = {Situation Recognition based on audio signals can be used to determine
situations in a meeting room while protecting the privacy by recording and
analyzing only the noise level instead of the complete audio signal.
A reliable situation recognition is normally obtained using Bayesian networks
which do not only rely on context information itself but additionally on
corresponding probabilities. Especially when the situation recognition itself
should output a quality rating to the determined situation it is necessary that
each analyzed information about all preconditions is rated with qualities or
probabilities. This leads to the need of a conversion from uncertainty to
probabilities when using sensor data to observe the environment to recognize
situations.
In this paper we compare different methods for situation recognition based on
noise level measurements. We implemented a Multilayer Perceptron Neural
Network, a simple empiric method and we describe the advantages of our method
based on multinomial logistic regression which we adapted to a reliable and
easily configurable situation recognition based on sensor data. To evaluate the
methods we distinguished between the situations {\^a}€œmeeting{\^a}€, {\^a}€œwork{\^a}€ and
{\^a}€œsilence{\^a}€ and recorded thousands of noise levels to calibrate and compare
the different methods against each other.
Our approach using logistic regression can be used as situation recognition
based on sensor data. It is not necessary that the input information contains
quality ratings but the system has to be calibrated with sensor data that can
be assigned to all the situations that have to be distinguished. Since the
result of this method contains probabilities to all situations it can also be
used to analyze sensor data related to single preconditions of complex
situation recognition algorithms based on Bayesian networks and different types
of context information.},

abstract = {Agents acting in physical space use perception in combination with their own
world models and shared context models to orient. The shared context models
have to be adapted permanently to the conditions of the real world. If a
measurement of an agent{\^a}€™s sensor does not fit to the corresponding data in
the shared context model the system contains an inconsistency. In this case it
is necessary to decide whether the reason for the discrepancy is a change in
the real world or a measurement error. If there is a change in the real world
the shared context model has to be corrected. A single agent can hardly answer
this question using its local world model. This work describes the scenario of
a context model that is shared with and updated by many agents that possess one
or more sensors. In occurrence of an inconsistency it is possible to call other
agents to validate a measurement. The functions to call the other agents are
provided by the Nexus platform, a federation of systems that manages users and
objects in shared dynamic context models. The study reported in this paper
evaluates procedures that combine a multitude of measurements to a single
result that can be integrated in the shared context model. The statistically
optimized procedure based on ratings of the participating agents is enhanced
using scaled weighted arithmetic means which prevents the system from running

attention since the beginning of this decade in both, the military and civil
domain. Although various conceptions exist of which capabilities are required
for a system to be considered network-centric or autonomous, there can hardly
be found proposals or prototypes that describe concrete transformations for
both capabilities into software. The presented paper reviews work accomplished
at EADS Military Air Systems driven by the need to develop an infrastructure
that supports the realisation of both concepts in software with respect to
traditional and modern software engineering principles, e.g., re-use and
service-oriented development. This infrastructure is provided in form of a
prototypical framework, accompanied by configuration and monitoring tools.
Tests in a complex scenario requiring network-centricity and autonomy have
shown that a significant technical readiness level can be reached by using the
framework for mission software development.},

abstract = {In this work we consider two families of piecewise-linear maps with a
discontinuity, which is motivated by modeling of several power electronic
circuits (DC/DC converters, Sigma-Delta modulators) and which is already
investigated by many authors. However, the focus of these works lie on the
investigation of the dynamics by variation of one or at most two system
parameters. In many of these publications a great variety of bifurcation
phenomena is revealed but unfortunately, a profound explanation of the
complicated and often self-similar bifurcation structures and the systematics
behind is missing. In contrast to that, we investigate the full 3D parameter
space of these families of systems and detect a number of discontinuity induced
codimension-3 bifurcations. Some of them belong to an already known generic
type [1,2], while others represent some new types not investigated so far.
Unfolding these bifurcations we are able to explain the systematics for a large
number of the above mentioned bifurcation phenomena. In particular, several
bifurcation scenarios observed under variation of one or two parameters
represent an intersection of the extended bifurcation structures induced by
codimension-3 bifurcation with the corresponding 1D or 2D parameter subspace.
The codimension-3 bifurcations reported here are characterized by two manifolds
in the 3D parameter space, a 1D and a 2D one. The 1D manifold represents a
codimension-2 bifurcation curve, whereas in the 2D manifold an infinite number
of codimension-2 bifurcation curves are located. At the codimension-3
bifurcation point all these curves intersect. The reported bifurcations serve
as organizing centers of periodic and aperiodic dynamics in the overall
parameter space. [1] V. Avrutin and M. Schanz, Nonlinearity 19, 531 (2006). [2]

abstract = {An aperiodic and especially a chaotic attractor may consist of some number K $>$=
1 of bands (also denoted as connected components). Multi-band chaotic
attractors (MBCAs) defined by the bandcount K $>$ 1, represent a well-known
phenomenon on the field of nonlinear dynamics and are often involved in several
bifurcations. It is for instance well-known, that the period doubling cascade
is typically followed by an inverse band merging cascade, which represents a
sequence of MBCAs with p0 2^n bands, whereby n decreases from infinity to zero.
We report a novel bifurcation scenario (bandcount adding scenario), which
involves an infinite number of MBCAs organized not sequentially, but according
to an infinite adding scheme. This adding scheme which is similar to the
well-known Farey-trees, implies that between two MBCAs with bandcounts K1 and
K2 there is an MBCA with K1 + K2 - K0 bands (with some constant offset K0).
This scenario continues ad infinitum and resembles the period adding scenario
known from many applications, but in contrast to this is formed by chaotic and
not by periodic attractors. We study this scenario using a discontinuous map,
which is actually considered by many authors as some kind of normal form of the
discrete-time representation of many non-smooth systems of practical interest
in the neighborhood of the point of discontinuity. By investigation of the
structure of the 2D parameter space, we find out, that the bandcount adding
scenario is related with discontinuityinduced codimension-1 bifurcations of
unstable periodic orbits and with some specific discontinuity-induced
codimension-2 bifurcations. Consequently, we describe the self-similarity of
the chaotic area in parameter space and show, that in this area there are much
more non-robust chaotic attractors than typically assumed.},

Dynamic conflicts between the robots are solved by the heuristic adjustment of
priority values. By a continuous enhancement of all plans the algorithm is very

abstract = {A software package for the simulation and investigation of dynamical systems
called AnT 4.669 will be presented in this paper. Due to its flexible
architecture, the AnT 4.669 software package is able to cope with dynamical
systems belonging to various classes, such as ordinary and recurrent maps,
ordinary, delayed, functional and partial differential equations currently with
only one spatial component. Further supported classes are: coupled maps,
coupled ordinary and delayed differential equations lattices as well as hybrid
systems, stochastic systems and external data. Many investigation methods are
implemented in the AnT 4.669 software package, like for instance general
trajectory evaluations, basic statistics, period and region analysis,
calculation of bifurcation diagrams, spectral analysis, principal component
decomposition, symbolic sequence evaluation and the calculation of Lyapunov
exponents using two different algorithms. Additionally a generalized
implementation of Poincar{\'e} sections and Poincar{\'e} return maps exists, with
several pre-implemented conditions and an additional possibility with a user
defined condition. Furthermore, the box-counting based calculation of the
invariant measure, the entropy and several fractal dimensions are available.
Additionally, a collection of investigation methods based on the calculation of
the symbolic image of a dynamical system is implemented. Using these methods,
one is able to determine stable and unstable invariant sets, stable and
unstable manifolds of fixed points and periodic orbits, as well as basins of
attraction. For dynamical systems discrete in time, the calculation of backward
orbits is implemented.
Another important feature of the AnT 4.669 software package, is the capability
to perform so-called scan runs, that is the ability to investigate a dynamical
system by varying one, two or even more relevant influence quantities, such as
the control parameters, initial values, or even some parameters of the
investigation methods, which is interesting in the context of optimizing the
results obtained by an investigation method. When dealing with scans in
high-dimensional parameter and/or state spaces, a significant advantage of the
AnT 4.669 software package is the distributed computing capability. This
capability is based on a client/server architecture and allows the calculation
of time consuming scan runs on an arbitrary number of computing nodes (both, in
homogeneous clusters as well as in heterogeneous networks).
The AnT 4.669 software package possesses also an interactive visualization
module, based on the OpenGL standard, which supports animations of trajectories
and an intuitive graphical user front-end, that guides a user of the system
through the complex initialization phase of a simulation run.
Finally there exists a web front-end to the AnT computation engine, which
allows the remote execution of simulation runs.
AnT 4.669 is free software (published under the GPL) and is available for
several UNIX as well as Windows platforms. More information about the
AnT-project can be found on the website: www.AnT4669.de.},

abstract = {Dynamical systems with a discontinuous system function represent a central
topic of many scientific works published in the recent years. This research
area is motivated by several practical applications, ranging from power
electronic circuits (for instance DC/DC converters) to mechanical systems with
impact or stick-slip phenomena, as well as hybrid and relay controlled systems.
In the field of nonlinear dynamics 1D maps with a piecewise-smooth system
function are well-known as return maps, obtained by the investigation of
Poincar$\backslash$'e sections of dynamical systems continuous in time. The discontinuity
of these return maps is caused by the stretching, squeezing and folding
phenomena, which are inherent for chaotic attractors. This discontinuity
represents a border in the state space, which leads to the basic property of
piecewise-smooth dynamical systems, namely their ability to undergo
border-collision bifurcations.
Multi-parametric bifurcations (also known as co-dimension-\$n\$ bifurcations with
\$n$>$1\$) are bifurcations, which can be adequately described only in an
\$n\$-dimensional parameter space. The characteristic property of these
bifurcations is, that at these points a number \$m$>$1\$ of \$(n-1)\$-dimensional
bifurcation hyper-surfaces (for instance, curves for \$n=2\$) intersect each
other. The fundamental consequence of this property is, that a single
bifurcation point of this type can dominate the dynamic behavior of the
investigated system in a large area of the \$n\$-dimensional parameter space.
Until now these phenomena were mostly investigated for smooth dynamical
systems. Several types of these bifurcations are known, like cusps,
double-Hopf, Shilnikov-Hopf, etc., which are induced by simple local
bifurcations (saddle-node, Hopf). In piecewise-smooth dynamical systems,
multi-parametric bifurcations can be induced by border-collision bifurcations
as well. In this work, we investigate an important special case of such a
bifurcation, where the aforementioned number \$m\$ is infinite.
Therefore, a 1D dynamical system, discrete in time, with a single point of
discontinuity is considered. This map has \$3\$ parameters and represents some
kind of normal form for maps with discontinuous system function. The part of
the 3D parameter space, where this map shows periodic dynamics, is investigated
in detail. It is demonstrated, that the behavior of the investigated map is
determined by border collision bifurcations, whereby the areas in the parameter
space leading to specific limit cycles can be obtained analytically. The main
result of the presented work is a detailed description of the multi-parametric
bifurcations in the investigated piecewise-linear map. The complete structure
of the 3D parameter space is described, and it is shown, that the investigated
map shows not only the usual one-parametric bifurcations, but also an infinite
number of two-parametric bifurcations. Additionally, it is shown, that in the
investigated system a three-parametric bifurcation occurs. It turns out, that
the complete structure of the 3D parameter space is reflected in the structure
of an infinite small vicinity of this bifurcation point. In other words: the
complete structure of the 3D parameter space can be explained and described by
the investigation of the single point, where this three-parametric bifurcation
occurs.},

abstract = {In dynamic and complex multi-robot scenarios, the task assignment is a
challenging and crucial topic, because it has to be very exible and robust or
in some sense fault-tolerant to achieve a certain degree of redundancy which is
often required in these scenarios. To cope with these requirements, a dynamic
task assignment approach based on selforganization principles adopted from
nature is presented. In this work, a team of soccer playing robots is used to
validate the suggested selforganized dynamic task assignment in dynamic domains
with real-time constraints.},

abstract = {The fundamental vision of modern nano-robotics is a swarm of micro-robots,
which is capable of performing tasks that are not possible with either a single
micro-robot, or even with a small group of micro-robots. Using principles of
artificial physics and self-organization for the control algorithms of such a
swarm of micro-robots, it is expected, that the swarm controlled in such a way
shows self-organized behavior similar to the self-organization phenomena
occurring in many biological or ecological systems like ant tribes, bee
colonies and other insect aggregations or flocking birds and shoals. There are
many potential benefits of such a system including greater flexibility and
adaptability to the environment, robustness to failures, compensation of
breakdowns from one or several units, etc.
In this work we describe a basic mathematical approach for modeling of the
swarm behavior and for developing the control software of individual
micro-robots. The approach is based on laws of artificial physics and coupled
hybrid automata. Designing the interaction patterns between robots, we are able
to achieve the desired self-organized behavior. For the modeling of these
interactions we use so-called virtual power functions (also known as social
powers). Depending on the complexity of the considered swarm scenarios,
specific classes of hybrid automata, namely degenerated, standard or
hierarchical ones, are used. In the last case complex swarm scenarios are
implemented using the concept of hierarchical self-organization. According to
this concept, the whole system consists of a hierarchy of subsystems. The most
simple subsystems (atomic entities, robots) build simple formations via a usual
self-organization process. In the presented approach these simple formations
are chains of robots with a pre-defined or variable length. Then the simple
formations operate as entities (non-atomic self-organized entities) and build
more complex formations via a self-organization process on the next hierarchy
level. Theoretically, the number of the self-organization levels in a
hierarchical self-organization process is not restricted, however in our
approach we restrict it firstly to two levels. This restriction is sufficient
in order to demonstrate the applicability of the presented concept and can be
extended in future work.
The application of the presented approach is demonstrated by example scenarios
with several complexity levels. Additionally, some techniques for the
investigation of the self-organization phenomena, applied from the fields of
coupled map lattices and hybrid systems, are discussed.},

singularities, which we denote as big bang bifurcation points. These
bifurcations can be observed only if two parameters are varied simultaneously
and cause an infinite number of different periodic dynamics. The investigated

complex self-similar structure of the 2D parameter space.},

recurrent network improves the robustness of a kinematic controller and
generates linear and angular velocities, necessary to track a reference
trajectory. In the second level, another network converts the desired
velocities, provided by the first level, into a torque control. The advantage
of the control approach is that, no knowledge about the dynamic model is
required, and no synaptic weight changing is needed in presence of parameters
variation. This capability is acquired through prior meta-learning. Simulation
results are demonstrated to validate the robustness of the proposed approach.},

beneficial to have special-purpose servers that are optimized for managing a

kinematic model is used, assuming that there is a dynamic controller that can
produce perfect velocity tracking. However, when the dynamic model of the robot
is considered, exact knowledge about its parameters is almost unattainable in
practical situations. In this paper, a novel recurrent neural network called
Echo-State Network is used to develop a dynamic-level controller, without
knowledge about the robot parameters. The control approach has been
experimentally tested on an omnidirectional mobile robot available at the
Robotics Lab of the University of Stuttgart.},

step of our research. For that, we examine some formal definitions and metrics
of scalability which fit the purpose of system description. The analysis of our
data integration solution, a change propagation system called Champagne,
identifies the system components having the most influence on the scalability

highway scenario. They rely on white lane markings with known geometric
appearance. Our method is an extension which also works when lane markings are
in bad conditions or are missing completely. We use re- ection posts as a means
of estimating the course of the road. In addition we are furthermore able to
measure the horizontal and vertical slope of the road surface.},

abstract = {Simulation has become an essential part in the development process of
autonomous robotic systems. In the domain of robotics, developers often are
confronted with problems like noisy sensor data, hardware malfunctions and
scarce or temporarily inoperable hardware resources. A solution to most of the
problems can be given by tools which allow the simulation of the application
scenario in varying degrees of abstraction and the suppression of unwanted
features of the domain (like e.g. sensor noise). The RoboCup scenario of
autonomous mobile robots playing soccer is one such domain where the above
mentioned problems typically arise.
In this work we will present a flexible simulation platform for the RoboCup
F2000 league developed as a joint open source project by the universities of
Freiburg and Stuttgart which achieves a maximum degree of modularity by a
plugin based architecture and allows teams to easily develop and share software
modules for the simulation of different sensors, kinematics and even complete
player behaviors.
Moreover we show how plugins can be utilized to implement benchmark tasks for
multi robot learning and give an example that demonstrates how the generic
plugin approach can be extended towards the implementation of hardware
independent algorithms for robot localization.},

abstract = {Sensor data evaluation and environment modeling represent a central part in the
design of robotic systems. The environment modeling process usually is done by
several data processing modules by means of sensor data fusion, combination of
a priori knowledge with currently sensed data, etc. Depending on the
application scenario there is usually a trade-off between accuracy and time
consumption of the environment modeling process. Some domains require a quite
accurate environment model and processing time plays a secondary role. More
reactive domains, however, demand for rather short cycle times, even if this
results in a less accurate model. For some applications the required degree of
accuracy may vary depending on the current situation or task to perform and
some parts of the sensed information may be more important than others. Several
architectures were proposed to address this problem by special mechanisms which
schedule the available resources according to the needs of the current tasks
which is usually denominated by the term ``selective'' or ``focused''
attention. In our work we will show how these concepts can be put into practice
by a flexible and open software design which is applied for our CoPs RoboCup
midsize team.},

paradox represents an example in which adding a new route to a specific
congested transportation network makes all the travelers worse off in terms of
their individual travel time. In the particular case in which the modeled
network corresponds to a binary choice situation, the map is defined on two
partitions and its dynamics has already been described. In the general case
corresponding to a ternary choice, a third partition appears leading to
significantly more complex bifurcation structures formed by border collision
bifurcations of stable cycles with points located in all three partitions.
Considering a map taking a constant value on one of the partitions, we provide
a first systematic description of possible dynamics for this case.},

period-adding scenario on the other hand, we denoted the new bifurcation
scenario as nested period-incrementing bifurcation scenario. The new
bifurcation scenario occurs in several physical and electronical systems but
usually not isolated, which makes the description complicated. By isolating the
scenario and using a suitable symbolic description for the asymptotically
stable periodic orbits, we derive a set of rules in the space of symbolic
sequences that explain the structure of the stable periodic domain in the
parameter space entirely. Hence, the presented work is a necessary step for the
understanding of the more complicated bifurcation scenarios mentioned above.},

square-root singularity. For particular choice of the parameters, this map
represents the normal form of discrete-time representation of impact oscillator
near grazing bifurcation. Owing to the nonlinearity, the map exhibits smooth
and nonsmooth bifurcations very closely related to each other. Our main aim is
to study how the nonlinearity influences the known results of nonsmooth
bifurcations and the interaction between smooth and nonsmooth bifurcations
considering the whole parameter space. We also explain the organizing source of
several atypical bifurcation phenomena using the concept of multi-parametric
bifurcation.},

abstract = {Agents acting in physical space use perception in combination with their own
world models and shared context models to orient. The shared context models
have to be adapted permanently to the conditions of the real world in dynamic
environments. If a measurement of an agent's sensor does not fit to the
corresponding data in the shared context model we get an inconsistency. In this
case it is necessary to decide whether the reason for the discrepancy is a
change in the real world or a measurement error. If there is a change in the
real world the shared context model has to be corrected. If the measurement is
erroneous it could be necessary to check the sensor. A single agent can hardly
answer this question using it's local world model. Extensive knowledge about
the represented world and the utilized sensors would be necessary. In this work
we examine the scenario of a context model that is shared with and updated by
many agents. In occurrence of an inconsistency it is possible to call other
agents to validate a measurement. The functions to call the other agents are
provided by the Nexus platform, a federation of systems that manages users and
objects in shared dynamic context models, integrates web technologies and
interfaces to the world wide web. We describe and evaluate procedures that
combine a multitude of measurements to a single result that can be integrated
in the shared context model. We enhanced the statistically optimized procedure
based on ratings of the participating agents. The procedure is altered so that
the system can recover from running into singularities caused by the feedback
from the ratings. In addition we describe a preprocessing based on fuzzy
clustering that detects aberrant measurements which are excluded from further
processing.},

abstract = {The assignment of distributed mobile autonomous robots to targets, which occurs
for instance as an important task in flexible manufacturing environments, is
solved by using a self-organization approach motivated by pattern formation
principles in biological, chemical and physical systems. Similar to
observerations in many natural systems, like ant tribes, pattern formation of
coloured shells or convection patterns in the Rayleigh-B{\'e}nard problem of fluid
dynamics, the selforganization principles lead to a robust and fault tolerant
behaviour where the patterns or structures recover from disturbances. The
considered problem is the dynamic assignment of a number of robots to given
targets where the mobile robots have to move to the targets in order to perform
some tasks there. Hereby, each robot uses only local information, i.e., no
world coordinate system is necessary. The underlying mathematical problem of
the robot-target assignment is the so-called two-index assignment problem from
combinatorial optimization. The used approach guarantees always feasible
solutions in the assignment of robotic units to targets. As a consequence, for
scenarios with only convex obstacles with large enough distances to each other,
no spurious states cause the assignment process to fail. The error resistant
control method for distributed autonomous robotic systems is demonstrated by
several experiments with mobile robots. These results are compared and
supplemented with computer simulations.},

abstract = {Using a one-dimensional dynamical system, representing a Poincare return map
for dynamical systems of the Lorenz type, we investigate the border-collision
period-doubling bifurcation scenario. In contrast to the classical
period-doubling scenario, this scenario is formed by a sequence of pairs of
bifurcations, whereby each pair consists of a border-collision bifurcation and
a pitchfork bifurcation. The characteristic properties of this scenario, like
symmetry-breaking and symmetry-recovering as well as emergence of coexisting
attractors and noninvariant attractive sets, are investigated.},

distributed planning, multi-agent systems (MAS) represent a promising approach
to achieve fault-tolerant selforganizing manufacturing systems. In this
article, a basic component of a manufacturingoriented MAS is presented. The
negotiation strategies are formulated in such a way that they, on the one hand,
guarantee considerable flexibility of the basic component itself, and, on the
other hand, enable the construction of more complex systems built up from
several components. On the basis of this single component, it is shown that the
dynamics of such systems without appropriate control mechanisms can be chaotic.
Such behaviour is, however, unwanted in practice and must therefore be
stabilized or avoided. In order to develop appropriate tools for this task, the
dynamic behaviour of the system is investigated using concepts and methods of
synergetics and the theory of nonlinear dynamical systems.},

abstract = {This work is based on the concept of order parameters of synergetics. The order
parameter equations describe the behavior of a system in the vicinity of an
instability and are used here not only for the analysis but also for the
control of nonlinear time discrete dynamical systems. Usually, the
dimensionality of the evolution equations of the order parameters is less than
the dimensionality of the original evolution equations. It is, therefore,
convenient to introduce control mechanisms, first in the order parameter
equations, and then to use the obtained results for the control of the original
system. The aim of the control in this case is to avoid chaotic behavior of the
system. This is achieved by shifting appropriate bifurcation points of a
perioddoubling cascade. In this work we concentrate on the shifting of only the
first bifurcation point. The used control mechanisms are delayed feedback
schemes. As an example the well-known Henon map is investigated. The order
parameter equation is calculated using both the adiabatic elimination procedure
and the center manifold theory. Using the order parameter concept two types of
control mechanisms are constructed, analyzed and compared.},

abstract = {Piecewise-smooth dynamical systems with discontinuous system function were
intensively investigated in the last years, motivated among other reasons by
many practical applications as well as by Poincar{\'e} return maps of dynamical
systems showing chaotic dynamics. However, bifurcations with co-dimension n$>$1
occurring in piecewise-smooth systems are still far away from being understood
completely.
In this work we investigate the properties of a special type of co-dimension
three bifurcation, which we have detected in several maps with discontinuous
system function. In the systems we consider, bifurcations with co-dimension one
are caused by simple border collisions. Looking at the 2D parameter spaces, we
detect some co-dimension two bifurcations points, where an infinite number of
co-dimension one bifurcation curves intersect. As a next step, we consider 3D
parameter spaces, and identify here the points, where an infinite number of
co-dimension two bifurcation curves intersect. These co-dimension three
bifurcations, reported by first time in, serve as organizing centers for
periodic and quasi-periodic dynamics. Unfolding these bifurcations, we are able
to explain several strange looking bifurcation structures, which are often
observed in 1D and 2D parameter subspaces and which are really difficult to
understand otherwise.
Further we investigate the boundaries of the influence areas of the detected
co-dimension three bifurcations. Such an influence area is defined as the union
of the stability areas of all periodic and quasi-periodic dynamics emerging at
the co-dimension three bifurcation point. Based on the structure of this
boundary we are able to explain and to classify transitions to chaos, which
occur at this boundary. Until now these transitions were reported in many
publications, but not explained systematically. \% Finally, tracking the paths
of the co-dimension three bifurcations in the 4D parameter space for one of the
investigated models, we demonstrate, that the overall structure of this 4D
parameter space is dominated by a single discontinuity induced co-dimension
four bifurcation.
The theoretical part of the work is illustrated by several applications
examples from the field of electronic circuits. Especially, some models of
DC/DC converters and \$$\backslash$Sigma/$\backslash$Delta\$ modulators are investigated in detail.},

abstract = {The occurrence of multi-band chaotic attractors (MBCA) represents a well-known
phenomenon on the field of nonlinear dynamics. For instance, the period
doubling cascade occurring in several dynamical systems is typically followed
by an inverse band merging cascade. Whereas the first one is formed by a
sequence of periodic attractors with periods \$p\_0 $\backslash$cdot 2^n\$ with increasing n,
the second one represents a sequence of MBCAs with \$p\_0 $\backslash$cdot 2^n\$ bands,
whereby n decreases from infinity to one. This bifurcation scenario is
well-known and investigated in detail. However, the question, which other types
of bifurcation scenarios can be caused by multi-band chaotic attractors and
their interactions with each other and with unstable orbits, is still
insufficiently investigated. When dealing with this question, it turns out,
that efficient algorithms for investigation of MBCAs are missing. The seemingly
simple question, how to determine the number of bands of a MBCA represents in
fact a hard task from the numerical point of view.
In this work two methods for the detection of the number of bands of a MBCA are
presented. The first one is developed for dynamical systems with a continuous
system function. It can be shown, that in this case the bands of a MBCA are
visited by an orbit in the same order for all times. This fact combined with
the mixing property of chaotic attractors allows us to solve the given task
efficiently, with low requirements with respect to computation time and memory
consumption. The second method does not use any assumptions concerning the
properties of the system function and hence can be applied to dynamical systems
with discontinuous system function as well. The price for this is the lower
convergence rate and the higher memory consumption.
For both methods we present the results of the performance tests, as well as
some techniques for ajustment of the parameters. Both methods are validated by
the investigation of scenarios in several well-known dynamical systems.
Using our second method we investigate some models of electronic cirquits of
practical interest (DC/DC converters and \$$\backslash$Sigma/$\backslash$Delta\$ modulators). These
models are intensively investigated in the last few years, especially due to
the increasing interest on dynamical systems with a discontinuous system
function. Hereby we present and explain a number of complex bifurcation
scenarios formed by MBCAs, not reported yet.
The developed methods are implemented within the AnT 4.669 package for
simulation and investigation of dynamical systems, which is free software and
can be downloaded from the website: www.AnT4669.de.},

abstract = {A software package for the simulation and investigation of dynamical systems
called AnT 4.669 will be presented in this paper. Due to its flexible
architecture, the AnT 4.669 software package is able to cope with dynamical
systems belonging to various classes, such as ordinary and recurrent maps,
ordinary, delayed, functional and partial differential equations currently with
only one spatial component. Further supported classes are: coupled maps,
coupled ordinary and delayed differential equations lattices as well as hybrid
systems, stochastic systems and external data. Many investigation methods are
implemented in the AnT 4.669 software package, like for instance general
trajectory evaluations, basic statistics, period and region analysis,
calculation of bifurcation diagrams, spectral analysis, principal component
decomposition, symbolic sequence evaluation and the calculation of Lyapunov
exponents using two different algorithms. Additionally a generalized
implementation of Poincare sections and Poincare return maps exists, with
several pre-implemented conditions and an additional possibility with a user
defined condition. Furthermore, the box-counting based calculation of the
invariant measure, the entropy and several fractal dimensions are available.
Additionally, a collection of investigation methods based on the calculation of
the symbolic image of a dynamical system is implemented. Using these methods,
one is able to determine stable and unstable invariant sets, stable and
unstable manifolds of fixed points and periodic orbits, as well as basins of
attraction. For dynamical systems discrete in time, the calculation of backward
orbits is implemented.
Another important feature of the AnT 4.669 software package, is the capability
to perform so-called scan runs, that is the ability to investigate a dynamical
system by varying one, two or even more relevant influence quantities, such as
the control parameters, initial values, or even some parameters of the
investigation methods, which is interesting in the context of optimizing the
results obtained by an investigation method. When dealing with scans in
high-dimensional parameter and/or state spaces, a significant advantage of the
AnT 4.669 software package is the distributed computing capability. This
capability is based on a client/server architecture and allows the calculation
of time consuming scan runs on an arbitrary number of computing nodes (both, in
homogeneous clusters as well as in heterogeneous networks). The AnT 4.669
software package possesses also an interactive visualization module, based on
the OpenGL standard, which supports animations of trajectories and an intuitive
graphical user front-end, that guides a user of the system through the complex
initialization phase of a simulation run. Finally there exists a web front-end
to the AnT 4.669 computation engine, which allows the remote execution of
simulation runs.
AnT 4.669 is free software (published under the GPL) and is available for
several UNIX as well as Windows platforms. More information about the AnT
4.669-project can be found on the website: www.AnT4669.de.},

abstract = {Dynamical systems with a discontinuous system function represent a central
topic of many scientific works published in the recent years. This research
area is motivated by several practical applications, ranging from power
electronic circuits (for instance DC/DC converters) to mechanical systems with
impact or stick-slip phenomena, as well as hybrid and relay controlled systems.
In the field of nonlinear dynamics 1D maps with a piecewise-smooth system
function are well-known as return maps, obtained by the investigation of
Poincar{\'e} sections of dynamical systems continuous in time. The discontinuity of
these return maps is caused by the stretching, squeezing and folding phenomena,
which are inherent for chaotic attractors. This discontinuity represents a
border in the state space, which leads to the basic property of
piecewise-smooth dynamical systems, namely their ability to undergo
border-collision bifurcations.
Multi-parametric bifurcations (also known as co-dimension-n bifurcations with
n$>$1) are bifurcations, which can be adequately described only in an
n-dimensional parameter space. The characteristic property of these
bifurcations is, that at these points a number m$>$1 of (n-1)-dimensional
bifurcation hyper-surfaces (for instance, curves for n=2) intersect each other.
The fundamental consequence of this property is, that a single bifurcation
point of this type can dominate the dynamic behavior of the investigated system
in a large area of the n-dimensional parameter space. Until now these phenomena
were mostly investigated for smooth dynamical systems. Several types of these
bifurcations are known, like cusps, double-Hopf, Shilnikov-Hopf, etc., which
are induced by simple local bifurcations (saddle-node, Hopf). In
piecewise-smooth dynamical systems, multi-parametric bifurcations can be
induced by border-collision bifurcations as well. In this work, we investigate
an important special case of such a bifurcation, where the aforementioned
number m is infinite.
Therefore, a 1D dynamical system, discrete in time, with a single point of
discontinuity is considered. This map has 3 parameters and represents some kind
of normal form for maps with discontinuous system function. The part of the 3D
parameter space, where this map shows periodic dynamics, is investigated in
detail. It is demonstrated, that the behavior of the investigated map is
determined by border collision bifurcations, whereby the areas in the parameter
space leading to specific limit cycles can be obtained analytically. The main
result of the presented work is a detailed description of the multi-parametric
bifurcations in the investigated piecewise-linear map. The complete structure
of the 3D parameter space is described, and it is shown, that the investigated
map shows not only the usual one-parametric bifurcations, but also an infinite
number of two-parametric bifurcations. Additionally, it is shown, that in the
investigated system a three-parametric bifurcation occurs. It turns out, that
the complete structure of the 3D parameter space is reflected in the structure
of an infinite small vicinity of this bifurcation point. In other words: the
complete structure of the 3D parameter space can be explained and described by
the investigation of the single point, where this three-parametric bifurcation
occurs.},
