Multiphysics Modeling of Electrochemical Conversion of Potassium Bicarbonate in Porous Electrode Flow Cell

Climate change is a pressing global crisis with far-reaching consequences, demanding the rapid advancement of clean energy technologies and effective carbon capture methods to mitigate Carbon Dioxide (CO₂) emissions. Carbon capture technologies offer a crucial pathway for capturing, storing, and reusing CO₂, thus...

Aeroacoustics of Airborne Wind Energy Systems

Airborne wind energy systems offer a promising approach for renewable energy generation. However, the noise emissions associated with these systems should be understood and minimized as well to promote their integration and (social) acceptance. This research aims to identify the noise sources of airborne wind energy systems, systems with leading...

Energy efficiency and treatment performance of BPM-ED for ammonium recovery from ammonium sulphate and ammonium citrate scrubbing effluents

Excess nitrogen disposal into the environment increased with the discovery of an artificial way of nitrogen gas conversion to ammonia, and its implementation to industrial scale. The excess wasted fixed nitrogen ended up in rivers, lakes, oceans which resulted in degrading air, water and soil due to exceedance of the amount of nitrogen that can...

Non-ohmic resistance of multiple ion-exchange membranes in series

This research aims to analyse the non-ohmic resistance of multiple ion-exchange membranes (IEM) in series, for a better understanding of membrane resistances. These membranes can be found in series in energy storage systems such as acid-base flow batteries (ABFB).<br/>The effect of different current densities on the ohmic and non-ohmic...

Agile software development and IT-architecture interactions in the public sector: A multi-case study approach to identify whether these roles are complementary or counterproductive

Large software projects often overrun costs, development time and do not deliver what has been envisioned by the customer. An important factor contributing to these cost overruns is the mismatch in the approaches of IT-architects and agile software development roles. In literature there are hints that complementary added value could be achieved...

Impact of audio codec and quality on genre classificaton and BPM recognition in Essentia

Music Information Retrieval (MIR) is a field of research that focusses on extracting information from music related data. This includes the genre of music and the beats per minute (BPM) of a song. Pipelines that extract this information from music are called feature extractors. Essentia is a library for such feature extraction. Often, the audio...

Electrodialysis with bipolar membranes for ammonia recovery in wastewater: An innovative concept for the treatment of ammonia residual streams

Municipal and industrial wastewater contains a significant amount of dissolved nitrogen. This is the results of the organic protein degradation and of the large employment of nitrogen (<i>N</i>), usually in the form of ammonia (<i>NH</i>₃), in the industry. Currently, nitrogen is removed in wastewater treatment plant (WWTP) by means...

Conducting CO2 reduction at a bipolar membrane electrode assembly: Combining known technological niches to achieve higher current densities

A comparative study of three different membrane electrode assemblies for electrochemical CO2 reduction is performed in a flowcell setup utilizing gaseous CO2 as a reagent. The membrane electrode assembly consists of a bipolar or exchange membrane, an Ag-mesh catalyst and a gas diffusion layer. The counterreaction occurring on the opposite of the...

Elastic-BPM: the Design, Deployment, and Evaluation of a Cloud-Based Architecture for Enterprise Business-Process-as-a-Service

Business processes are part of every company’s daily business. In the past hundreds of years, almost every aspect in the operation of businesses has seen a two-pronged transformation: first, toward defining and then following processes, and second, toward making the processes efficient through the use of technology.<br/>In this work, we define a...

Design and Noise Study of a Low-Drag Wind Turbine for Airborne Power Applications: A Numerical and Experimental assesment

The Impact of Social Business Process Management on Policy-making in e-Government

The combination of social media and Business Process Management (BPM) has given rise to the emerging field of “social BPM”. The new development of social BPM is expected to provide benefits like flexibility for knowledge-intensive processes, like policy-making. The goal of this paper is to understand the impact of social BPM on policy-making. We...

Evaluating the State-of-the-Art in Business Process Management Tools and Methodologies

Although people have tried to control processes for centuries, with the more recent introduction of larger economies-of-scale and the toughening economic environment organisations are increasingly interested in improving their business processes. This has resulted in the emergence of Business Process Management (BPM), a field that has quickly...

Round-trip Business Process Driven SOA modelling between ARIS and Cordys

Business process modelling is the core activity in Business Process Driven SOA. ARIS is as Business Process Analysis (BPA) tool adequate for analyzing and designing business processes, while the execution and monitoring of these processes is empowered by Cordys as Business Process Management Suite (BPMS). The challenge is to enable iterative...
