Building blocks are a ubiquitous feature at all levels of human understanding, from perception through science and innovation. Genetic algorithms are designed to exploit this prevalence. A new, more robust class of genetic algorithms, cohort genetic algorithms (cGA’s), provides substantial advantages in exploring search spaces for building blocks while exploiting building blocks already found. ...

This paper presents concepts for dealing with topological information in building information models. On the one hand, it shows how to derive topological relationships from ``traditional'' building models consisting of unconnected B-Rep bodies by means of geometric processing algorithms. On the other hand, it discusses the capabilities of topological building modeling based on relational comple...

As the driving forces of technological change continue to increase exponentially as predicted by Moores’ law, we have been witnessing in the last years major breakthroughs in the fields of wireless and mobile communications as well as unprecedented proliferation of multimedia enabled devices and networks. These devices can consume remote multimedia contents by connecting wirelessly through diff...

The Software Defined Radio (SDR) is a class of reprogrammable and reconfigurable radios which can be switched from one air-interface to another. It is generally employed in software, which can be easily realized on base station side. On terminal side, the configurability of the radio has to be maintained in a hybrid architecture consist of both software as well as hardware, due to computational...

The first neutron spectrometer of ASDEX Upgrade (AUG) was installed in November 2008. It is a compact neutron spectrometer (CNS) based on a BC501A liquid scintillating detector, which can simultaneously measure 2.45-MeV and 14-MeV neutrons emitted from deuterium (D) plasmas and γ radiation. The scintillating detector is coupled to a digital pulse shape discrimination data acquisition (DPSD) sys...

With the advent of the new wireless technologies allowing for higher data rates, the provision of high quality multimedia services over the upcoming wireless and mobile networks is gaining momentum. These future mobile networks are witnessed to consist of a variety of heterogeneous wireless access technologies connected to a high-speed IP datagram-based core network. The heterogeneity of these ...

Since broadband network connections are becoming ubiquitous, people expect access to multimedia content anywhere anytime. This new demand results in a need to create and develop new, powerful devices for multimedia consumption. The new devices, each having their set of network and terminal capabilities, allow transparent access to multimedia and therefore open the path to transparent mobility o...

Heterogeneous sharing in synchronous collaboration is important with the proliferation of diverse computing environments, such as wearable computers and handheld devices. We present here a data-centric design for synchronous collaboration of users with heterogeneous computing platforms. Our approach allows clients with different capabilities to share different subsets of data in order to conser...

Estimating flood risks and managing disasters combines knowledge in climatology, meteorology, hydrology, hydraulic engineering, statistics, planning and geography – thus a complex multi-faceted problem. This study focuses on the capabilities of multi-source remote sensing data to support decision-making before, during and after a flood event. With our focus on urbanized areas, sample methods an...

In this paper we report a case study on how firms realize the business value of CRM by developing CRM-enabled ambidexterity to simultaneously pursue stability and develop adaptability. Results show that as the focal firm used CRM as a platform for standardizing operations and building routines, the top management team (TMT) and the operation team worked together to reflexively monitor the statu...
