Characterization of Nanomaterials: Selected Papers from 6th Dresden Nanoanalysis Symposiumc

This Special Issue “Characterization of Nanomaterials” collects nine selected papers presented at the 6th Dresden Nanoanalysis Symposium, held at Fraunhofer Institute for Ceramic Technologies and Systems in Dresden, Germany, on 31 August 2018. Following the specific motto of this annual symposium “Materials challenges—Micro- and nanoscale characterization”, it covered various topics of nanoscale materials characterization along the whole value and innovation chain, from fundamental research up to industrial applications. The scope of this Special Issue is to provide an overview of the current status, recent developments and research activities in the field of nanoscale materials characterization, with a particular emphasis on future scenarios. Primarily, analytical techniques for the characterization of thin films and nanostructures are discussed, including modeling and simulation. We anticipate that this Special Issue will be accessible to a wide audience, as it explores not only methodical aspects of nanoscale materials characterization, but also materials synthesis, fabrication of devices and applications

Hardware-in-the-Loop Co-Simulation Based Validation of Power System Control Applications

Renewables are key enablers for the realization of a sustainable energy supply but grid operators and energy utilities have to mange their intermittent behavior and limited storage capabilities by ensuring the security of supply and power quality. Advanced control approaches, automation concepts, and communication technologies have the potential to address these challenges by providing new intelligent solutions and products. However, the validation of certain aspects of such smart grid systems, especially advanced control and automation concepts is still a challenge. The main aim of this work therefore is to introduce a hardware-in-the-loop co-simulation-based validation framework which allows the simulation of large-scale power networks and control solutions together with real-world components. The application of this concept to a selected voltage control example shows its applicability.Comment: 2018 IEEE 27th International Symposium on Industrial Electronics (ISIE

1st Process systems engineering & safety (ProSES) symposium 2019 preface

The special issue of 1st ProSES Symposium is a collection of invited contributions from the presenters of the inaugural Process Systems Engineering & Safety (ProSES) Symposium, organized by Process Systems Engineering & Safety (ProSES) Research Group, Faculty of Chemical and Process Engineering Technology, formally known as the Faculty of Chemical and Natural Resources Engineering, Universiti Malaysia Pahang, on 4th September 2019 in Kuantan, Pahang, Malaysia. The theme for the 1st ProSES Symposium 2019 is The Role of Modelling and Simulation Towards IR 4.0, since the emergence of IR4.0 technology provides the opportunity for dramatically increasing the reliability and efficiency in production operations of many industrial sectors including chemical-based processing. Hence, it is the aim of this conference to provide the platform for intellectual discourse for the application of computer aided tools for modelling and simulation in the area of process systems engineering and safety particularly in the era of IR4.0, and related topics. 1st ProSES Symposium 2019 attracted more than 60 extended abstracts submissions. Two keynote speakers delivered their particularly interesting topics – Professor Ir Dr Haslenda Hashim from Universiti Teknologi Malaysia with a talk on "Process Modelling and Simulation Toward IR4.0"; and Professor Dr Azmi Mohd Shariff from Universiti Teknologi Petronas on "Process Safety in IR4.0"

ptp++: A Precision Time Protocol Simulation Model for OMNeT++ / INET

Precise time synchronization is expected to play a key role in emerging distributed and real-time applications such as the smart grid and Internet of Things (IoT) based applications. The Precision Time Protocol (PTP) is currently viewed as one of the main synchronization solutions over a packet-switched network, which supports microsecond synchronization accuracy. In this paper, we present a PTP simulation model for OMNeT++ INET, which allows to investigate the synchronization accuracy under different network configurations and conditions. To show some illustrative simulation results using the developed module, we investigate on the network load fluctuations and their impacts on the PTP performance by considering a network with class-based quality-of-service (QoS) support. The simulation results show that the network load significantly affects the network delay symmetry, and investigate a new technique called class probing to improve the PTP accuracy and mitigate the load fluctuation effects.Comment: Published in: A.
