Parametric analysis of a double shaft batch-type paddle mixer: A DEM study

The Discrete Element Method (DEM) in combination with an One Factor At a Time (OFAT) experimental simulation plan were employed to investigate the effect of a selection of factors on the mixing performance of a double shaft, batch-type paddle mixer. Most influential factors on the mixing performance of the paddle mixer are desired for...

An Empirical Estimation on the Impact of Freight Traffic on the Capacity Drop

In recent years, the amount of traffic on the highways has increased continuously and in particular freight traffic. Despite solutions to maximize roadway capacity, the drop of capacity after congestions sets in, remains an active field of study. The influence of freight traffic on traffic flow has received little attention, especially regarding...

Propeller Slipstream Correction for Wind Tunnel Applications: A panel method approach to model propeller induced rotational flow for aircrafts in mid/high thrust condition

In the post processing of acquired wind tunnel force measurements, propeller-driven aircrafts need a preliminary correction of the propeller slipstream. Propeller slipstream effect has two major contributions to the flow field. The first one is the increase in dynamic pressure and the second is the addition of rotation in the flow field. Without...

Determined-Safe Faults Identification: A step towards ISO26262 hardware compliant designs

The development of Integrated Circuits for the Automotive sector imposes on major challenges. ISO26262 compliance, as part of this process, entails complex analysis for the evaluation of potential random hardware faults. This paper proposes a systematic approach to identify faults that do not disrupt safety-critical functionalities and...

Combining Fault Analysis Technologies for ISO26262 Functional Safety Verification

The development of Integrated Circuits for the Automotive sector imposes on complex challenges. ISO26262 Functional Safety requirements entail extensive Fault Injection campaigns and complex analysis for the evaluation of deployed Software Tools. This paper proposes a methodology to improve Fault Analysis Tools Confidence Level (TCL) by...

Validating the effect of the persuasive game design principle simulation on attitude change for multi-actor decision-making

Persuasive games have great properties for facilitating lasting attitude change for complex societal issues, making them a valuable tool for achieving attitude change towards cooperation and information sharing that is often necessary for effective multi-actor decision-making. It is assumed that persuasive game design principles are key drivers...

Storage assignment of (semi-)finished products in an environment with multiple plants, warehouses, and production lines

Manufacturing systems are becoming increasingly complex with the involvement of several plants, dozens of production lines, and thousands of different SKUs. Products have to be stored between the production stages, and the export to the end-users. Within this context, storage assignment decisions are crucial in order to reduce the number of...

Towards an approach integrating various levels of data analytics to exploit product-usage information in product development

By applying data analytics to product usage information (PUI) from combinations of different channels, companies can get a more complete picture of their products' and services' Mid-Of-Life. All data, which is gathered within the usage phase of a product and which relates to a more comprehensive understanding of the usability of the product...

Simulation of shotnoise induced side-wall roughness in electron lithography

We have developed a fast three dimensional Monte-Carlo framework for the investigation of shotnoise induced side-wall roughness (SWR) formation. The calculation outline is demonstrated by an example for an exposure of a 100nm thick layer of negative tone resist (NTR) resist on top of an infinitely thick silicon substrate. We use our home...
