Simulation and realization of a focus shifting unit using a tunable lens for 3D laser material processing
(2013)Physics Procedia ~ Lasers in Manufacturing (LiM 2013)3D laser microprocessing using current market available technologies reveals itself to be a cost intensive and complex undertaking which is mostly due to the control architecture and use of moving components. Recent market appearance of electronically tunable lenses exhibiting NIR transmission, large aperture, high damage threshold and fast response times are available for laser based applications. Hence, enabling usage in the field of ...Conference Paper -

Super-finished Surfaces using meso-micro EDM
(2013)Procedia CIRP ~ Proceedings of the Seventeenth CIRP Conference on Electro Physical and Chemical Machining (ISEM)A novel stochastic orbiting strategy combined with extremely low stray capacitance sinking EDM machine offers the capability to achieve super-finished surfaces (Ra <0.1 μm) without pre-polishing of the copper tool electrodes. Surface defects such as inhomogeneity, cracks, arc spots and black spots have been analysed and reduced, while improving material removal rate with lower tool wear. Super-finished surfaces thus generated have uniform ...Conference Paper -
Influence of Workpiece Circumferential Speed in Wire Electrical Discharge Machining
(2013)Procedia CIRP ~ Proceedings of the Seventeenth CIRP Conference on Electro Physical and Chemical Machining (ISEM)In Wire Electrical Discharge Machining (WEDM) a specific wire run-off speed is applied to compensate wear and avoid wire breakage. Since the workpiece generally stays stationary and short discharge durations are applied, the relative displacement between wire and workpiece during one single discharge is very small. In Wire Electrical Discharge Dressing (WEDD), however, the workpiece rotates at very high circumferential speeds, since ...Conference Paper -
Mapping behavioral specifications to model parameters in synthetic biology
(2013)BMC BioinformaticsWith recent improvements of protocols for the assembly of transcriptional parts, synthetic biological devices can now more reliably be assembled according to a given design. The standardization of parts open up the way for in silico design tools that improve the construct and optimize devices with respect to given formal design specifications. The simplest such optimization is the selection of kinetic parameters and protein abundances ...Conference Paper -

Robust Routing in Urban Public Transportation: How to Find Reliable Journeys Based on Past Observations
(2013)OpenAccess Series in Informatics (OASIcs) ~ 13th Workshop on Algorithmic Approaches for Transportation Modelling, Optimization, and Systems (ATMOS 2013)We study the problem of robust routing in urban public transportation networks. In order to propose solutions that are robust for typical delays, we assume that we have past observations of real traffic situations available. In particular, we assume that we have "daily records" containing the observed travel times in the whole network for a few past days. We introduce a new concept to express a solution that is feasible in any record of ...Conference Paper -
Identified hadron spectra in p+p interactions at 20, 31, 40, 80 and 158 GeV/c from NA61/SHINE at the CERN SPS
(2013)PoS: Proceedings of Science ~ 8th International Workshop on Critical Point and Onset of Deconfinement (CPOD 2013)The NA61/SHINE experiment aims to discover the critical point of strongly interacting matter and study the properties of the onset of deconfinement. These goals are achieved by measurements of hadron production properties in nucleus-nucleus, proton-proton and proton-nucleus interactions as a function of collision energy and size of the colliding nuclei. In this contribution, inclusive spectra of identified hadrons in p+p interactions at ...Conference Paper -
Scripting Cultures, Parametric Urbanism and Adaptive Ecologies
(2013)Workshop Proceedings of the 9th International Conference on Intelligent EnvironmentsThis paper aims to examine how the role of the architect has changed as we shifted to the process of design that Kostas Terzidis calls “Algorithmic Architecture”. The relationships between subjects and objects have changed and thanks to Computer-Assisted Conception and Fabrication (CFAO) systems we are able to manufacture different shapes of each object in the same series. In order to address the problem of global ecological crisis we ...Conference Paper -
