abstract = {Location-based services (LBS) have to cope with increasing query loads at their
data tier. Yet, the data access patterns of LBS typically possess spatial
locality. Therefore, a dedicated spatial cache which provides efficient access
to the data currently needed may considerably reduce this load. To ensure high
throughput throughout the entire execution, previous work introduced an elastic
load-balancing mechanism for multiple cache nodes that collaborate in a
distributed spatial cache overlay. However, calibrating such a load-balancing
mechanism is a non-trivial task, as several parameters influence such a system.
We demonstrate a simulation platform (SimPl) for elastic load-balancing. SimPl
enables a network administrator to set up several overlay topologies and
calibrate their system parameters using different spatial data access patterns.
A live visualization of the simulated overlay enables intuitive comparison of
overlay topologies and their load-balancing abilities.},

abstract = {Location-based services (LBS) have gained enormous popularity, which imposes
increasing query loads at the data tier of an LBS. Yet, the data access
patterns of LBS typically possess high temporal and spatial locality.
Therefore, a dedicated spatial cache which provides efficient access to the
data currently needed may considerably reduce this load. To ensure high
throughput, multiple cache nodes can collaborate in a distributed spatial cache
overlay, which balances load among the nodes. However, load-balancing is a
non-trivial task in this context, as load spreads unevenly in space and varies
notably over time. This requires constant readjustment to shifting hot spots.
We present an elastic load-balancing mechanism between cache nodes that is
based on the physical model of a particle-spring system. Using spring
contraction, nodes instantly form processing clusters in regions with high load
and thus can easily work off accumulating queries. Our evaluation shows that
our approach quickly adapts to rapidly changing hot spots and thereby ensures
high throughput throughout the entire execution.},

increasingly leading to a highly connected environment equipped with sensors
producing a continuous flow of context data. The steadily growing number of
sensory context data available enables new application scenarios and drives new
processing techniques. The growing pervasion of everyday life with social media
and the possibility of interconnecting them with moving objects{\^a}€™ traces,
leads to a growing importance of access control for this kind of data since it
concerns privacy issues. The challenge in twofold: First mechanisms to control
data access and data usage must be established and second efficient and
flexible processing of sensible data must be supported. In this paper we
present a flexible and extensible security framework which provides mechanisms
to enforce requirements for context data access and beyond that support safe
processing of sensible context data according to predefined processing rules.
In addition and in contrast to previous concepts, our security framework
especially supports fine-grained control to contextual data.},

Product Lifecycle Management Technology (PLM) the growing heterogeneous IT
landscapes lack of a continuous support for business processes and get quickly

developed which will be presented in detail. The architecture describes how the

abstract = {The number of pervasive games is growing. In a pervasive game players have to
interact with their environment in order to control their avatar. While in the
past such a game required immense hardware equipment, nowadays, Smartphones
have all required functionality built-in already. In addition, there is an
upcoming trend towards software, supported with new content and knowledge by an
active community. By combining these two trends, a new genre for computer games
arises, targeting not only established gamers but also a new audience. In this
paper we present a framework for pervasive games that support various
customization techniques. Therefore, we divided the techniques into four
classes depending on the player’s technical knowledge and scale of adaption
potential. Further, we present two customizable pervasive games we have
implemented using the framework. Concluding, we show the potential of these
games as well as the potential of our framework. We also report on early
experiences in exploiting the customization approach of our framework.},

Service Oriented Architecture (SOA) is a prevalent solution to efficiently
integrate legacy applications and systems into business processes. Its
possibility for loose coupling of services enables the replacement of

maintaining the IT infrastructure. This article introduces a SOA-based solution
to the integration of all PLM phases. We employ an Enterprise Service Bus (ESB)
as service-based integration and communication infrastructure and introduce
three exemplary scenarios to illustrate the benefits of using an ESB as
compared to alternative PLM infrastructures. Furthermore, we describe a service
hierarchy that extends PLM functionality with value-added services by mapping
