Influence of the anode material on the breakdown behavior in dry electrical eischarge machining
(2012)Procedia CIRP ~ Fifth CIRP Conference on High Performance Cutting 2012In the last years dry electrical discharge machining (DEDM) has been proposed as an alternative to the traditional EDM. The main reason for these efforts is the absence of a liquid dielectric which results in a simpler and environmentally friendly machine. This paper presents measurements of the material removal rate in function of different tool electrode and work piece material put in relation with the breakdown behavior of the process ...Conference Paper -
Development of a Reliable Packaging for CMOS-based Microelectrode Arrays by Using an Automated Setup
(2014)Procedia Engineering ~ EUROSENSORS 2014, the 28th European Conference on Solid-State TransducersWe present a reliable and versatile microelectrode-array-device-packaging method for use in neurobiological research. The new packaging is simple, user-friendly, durable, and obviates any contamination of the sensitive electrodes (Figure 1). The packaging consists of a custom-designed injection-molded polycarbonate ring that is bonded to the surface of the CMOS chip with a specifically selected biocompatible adhesive. The utilization of ...Conference Paper -
Vibration-based Damage Identification in the UHPFRC Strengthened Buna bridge
(2019)ANCRiSST 2019 Procedia 14th International Workshop on Advanced Smart Materials and Smart Structures TechnologyThe Buna Bridge in Croatia, a steel riveted bridge from 1893, was decommissioned in 2010. As part of a research investigation, the structure was rehabilitated and strengthened by means of a novel method, comprising a lightweight slab made of Ultra High Performance Fiber Reinforced Cementituos-composite (UHPFRC) atop the main girders, acting in composite action with them. An extensive experimental campaign was carried out in the laboratory, ...Conference Paper -

Watersheds and explosive percolation
(2011)Physics ProcediaThe recent work by Achlioptas, D'Souza, and Spencer opened up the possibility of obtaining a discontinuous (explosive) percolation transition by changing the stochastic rule of bond occupation. Despite the active research on this subject, several questions still remain open about the leading mechanism and the properties of the system. We review the largest cluster and the Gaussian models recently introduced. We show that, to obtain a ...Conference Paper -
Temperature Controlled Viscosity and Density Measurements on a Microchip with High Resolution and Low Cost
(2011)Procedia Engineering ~ Eurosensors XXVA chip-based viscosity and density sensor which requires a sample volume of less than 10 colonl is presented. A resistive heater and a temperature sensor are provided for accurate and fast temperature dependent measurements. An inductive readout of the resonance frequency and the damping further facilitates the measurement procedure. Thereby high resolution measurements of fluid properties are easily made in view of their analysis in the ...Conference Paper -
Globally Distributed Engineering Processes: Making the Distinction between Engineer-to-order and Make-to-order
(2014)Procedia CIRP ~ Variety Management in Manufacturing: Proceedings of the 47th CIRP Conference on Manufacturing SystemsThis paper explores how the organizational and technological requirements of globally distributed engineering processes differ for make-to- order (MTO) and engineer-to-order (ETO) production and highlights potential research themes which might contribute to a better understanding of this field. The preliminary results presented in this paper are based on a literature review and an on-going exploratory case study with manufacturers from ...Conference Paper -
The Role of Water in Adsorption-based CO2 Capture Systems
(2013)Energy Procedia ~ GHGT-11 Proceedings of the 11th International Conference on Greenhouse Gas Control TechnologiesCyclic adsorption processes such as Pressure, Temperature, and Vacuum Swing Adsorption have received increased attention as potential techniques for the capture of CO2 from gas mixtures in industrial processes. A key challenge in the design of these processes is to gain a thorough understanding of the interactions between the numerous gas phase components and the sorbent material, as an effective separation requires a selective adsorption ...Conference Paper -
Design of a 100 MWh(th) packed-bed thermal energy storage
(2014)Energy Procedia ~ Proceedings of the SolarPACES 2013 International ConferenceA thermal energy storage (TES) system was designed based on a packed bed of rocks as storing material and air as heat transfer fluid. A pilot-scale 6.5 MWhth TES unit was built and tested. A dynamic numerical heat transfer and fluid flow model was developed and experimentally validated with measurements obtained from the pilot-scale TES unit. The simulation model is applied to design an industrial-scale 100 MWhth TES unit for a solar power ...Conference Paper -
Geothermal energy production at geologic CO2 sequestration sites: Impact of thermal drawdown on reservoir pressure
(2013)Energy Procedia ~ GHGT-11 Proceedings of the 11th International Conference on Greenhouse Gas Control TechnologiesRecent geotechnical research shows that geothermal heat can be efficiently mined by circulating carbon dioxide through naturally permeable rock formations -- a method called CO2 Plume Geothermal -- the same geologic reservoirs that are suitable for deep saline aquifer CO2 sequestration or enhanced oil recovery. This paper describes the effect of thermal drawdown on reservoir pressure buildup during sequestration operations, revealing that ...Conference Paper
