The cell set-up is suitable for using powder electrode materials. Reproducibility of our cell assembly is analyzed by preparing two cells containing hard carbon (HC) powder as working electrode and sodium metal as reference electrode. Electrochemical storage properties of HC powder electrode derived from carbonization of sustainable cellulose are studied by ssNMR. 23Na in-situ ssNMR monitors the sodiation/desodiation of a Na{\\textbar}NaPF6{\\textbar}HC cell (cell 1) over a period of 22?days, showing high cell stability. After the galvanostatic process, the HC powder material is investigated by high resolution 23Na ex-situ MAS NMR. The formation of ionic sodium species in different chemical environments is obtained. Subsequently, a second Na{\\textbar}NaPF6{\\textbar}HC cell (cell 2) is sodiated for 11?days achieving a capacity of 220?mAh/g. 23Na ex-situ MAS NMR measurements of the HC powder material extracted from this cell clearly indicate the presence of quasi-metallic sodium species next to ionic sodium species. This observation of quasi-metallic sodium species is discussed in terms of the achieved capacity of the cell as well as of side reactions of sodium in this electrode material.","lang":"eng"}],"status":"public"},{"title":"Re-Envisioning Industrial Control Systems Security by Considering Human Factors as a Core Element of Defense-in-Depth","publisher":"IEEE","date_created":"2023-08-15T12:21:05Z","year":"2023","quality_controlled":"1","keyword":["Defense-in-Depth","Human Factors","Production Engineering","Product Design","Systems Engineering"],"ddc":["000"],"language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"The security of Industrial Control Systems is relevant both for reliable production system operations and for high-quality throughput in terms of manufactured products.

In contrast, the in situ computed tomography (CT) can provide three-dimensional images of the clinch point under loading conditions. In this paper, the potential of the in situ investigation of a clinching process as validation method is analyzed. For the in situ testing, a tailored test set-up featuring a beryllium cylinder for load-bearing and clinching tools made from ultra-high-strength titanium and Si3N4 are used. In the experiments, the clinching of two aluminum sheets is interrupted at specific process steps in order to perform the CT scans.

This study empirically examines how academics’ citation patterns have changed in response to the rise of an “evaluation environment” in academia. We regard the WURs to be a macro-level trigger for cementing a bibliometric-based evaluation environment in academia. Our analyses of citation patterns in papers published in two higher education journals explicitly considered three distinct periods: the pre-WURs (1990–2003), the period of WURs implementation (2004–2010), and the period of adaption to WURs (2011–2017). We applied the nonparametric Kaplan–Meier method to compare first-citation speeds of papers published across the three periods. We found that not only has first-citation speed become faster, but first-citation probability has also increased following the emergence of the WURs. Applying Cox proportional hazard models to first-citation probabilities, we identified journal impact factors and third-party funding as factors influencing first-citation probability, while other author- and paper-related factors showed limited effects. We also found that the general effects of different factors on first-citation speeds have changed with the emergence of the WURs. The findings expand our understanding of the citation patterns of academics in the rise of WURs and provide practical grounds for research policy as well as higher education policy.</jats:p>","lang":"eng"}],"file":[{"access_level":"closed","file_name":"Lee et al. 2021 Academic Citations.pdf","file_id":"33375","file_size":2407463,"date_created":"2022-09-15T08:36:50Z","creator":"isste","date_updated":"2022-09-15T08:36:50Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"publication":"Sustainability"},{"date_updated":"2023-02-28T08:58:24Z","date_created":"2021-09-16T08:33:04Z","author":[{"first_name":"Oliver","last_name":"Müller","id":"72849","full_name":"Müller, Oliver"},{"first_name":"Matthew","full_name":"Caron, Matthew","id":"60721","last_name":"Caron"},{"last_name":"Döring","full_name":"Döring, Michael","first_name":"Michael"},{"full_name":"Heuwinkel, Tim","last_name":"Heuwinkel","first_name":"Tim"},{"first_name":"Jochen","full_name":"Baumeister, Jochen","id":"46","last_name":"Baumeister","orcid":"0000-0003-2683-5826"}],"title":"PIVOT: A Parsimonious End-to-End Learning Framework for Valuing Player Actions in Handball using Tracking Data","conference":{"start_date":"2021-09-13","name":"European Conference on Machine Learning and Principles and Practice of Knowledge Discovery (ECML PKDD 2021)","location":"Online","end_date":"2021-09-17"},"main_file_link":[{"url":"https://dtai.cs.kuleuven.be/events/MLSA21/papers/MLSA21_paper_muller.pdf"}],"publication_status":"inpress","year":"2021","citation":{"chicago":"Müller, Oliver, Matthew Caron, Michael Döring, Tim Heuwinkel, and Jochen Baumeister. “PIVOT: A Parsimonious End-to-End Learning Framework for Valuing Player Actions in Handball Using Tracking Data.” In <i>8th Workshop on Machine Learning and Data Mining for Sports Analytics (ECML PKDD 2021)</i>, n.d.","ieee":"O.

Accounting for the fast-paced, dynamic nature and relative data scarcity of hand- ball, we propose a parsimonious end-to-end deep learning architecture that relies solely on tracking data. This efficient approach is capable of predicting the probability that a team will score within the near future given the fine-grained spatio-temporal distribution of all players and the ball over the last seconds of the game. Our experiments indicate that PIVOT is able to produce accurate and calibrated probability estimates, even when trained on a relatively small dataset.

We regard timing in two dimensions, namely the time of announcement in relation to the time of investment and the time of announcement in relation to the time of a fundamental security incident. The financial value of information security investments is assessed by examining the relationship between the investment announcements and their stock market reaction focusing on the two time dimensions. Using an event study methodology, we found that both dimensions influence the stock market return of the investing organization. Our results indicate that (1) after fundamental security incidents in a given industry, the stock price will react more positively to a firm’s announcement of actual information security investments than to announcements of the intention to invest; (2) the stock price will react more positively to a firm’s announcements of the intention to invest after the fundamental security incident compared to before; and (3) the stock price will react more positively to a firm’s announcements of actual information security investments after the fundamental security incident compared to before. Overall, the lowest abnormal return can be expected when the intention to invest is announced before a fundamental information security incident and the highest return when actual investing after a fundamental information security incident in the respective industry."}],"file":[{"relation":"main_file","content_type":"application/pdf","file_size":478056,"file_id":"16250","access_level":"open_access","file_name":"Timing in Information Security - JISSEC format PREPUBLICATION.pdf","date_updated":"2020-03-05T10:35:49Z","date_created":"2020-03-05T10:26:11Z","creator":"hsiemes"}],"keyword":["Event Study","Information Security","Investment Announcements","Stock Price Reaction","Value of Information Security Investments"],"ddc":["000"],"language":[{"iso":"eng"}]},{"intvolume":"        42","page":"1234-1257","citation":{"apa":"Hoellger, C., Sommer, S., Albert, I., &#38; Buhl, H.

Regarding relationship quality, verbal intimacy was not related to value similarity. Parental satisfaction was associated with value similarity in the father–child dyads. Satisfaction, as perceived by adult children, was linked to value similarity in mother–child and father–son dyads.

A well-defined manipulation of atomization may be achieved by variation of nozzle geometry, injection parameter or fluid properties. However, change of fluid properties, e.g. varying solvents or increasing the precursor concentration, also influences the final particle properties. In this work, the influence of precursor concentration on fluid properties, spray and particle formation in Flame Spray Pyrolysis is experimentally investigated. High-speed shadowgraphy and Phase-Doppler measurements are conducted in a semi-closed combustion chamber with a well-defined burner geometry (SpraySyn burner) that is based on a coaxial atomization principle. By adding precursor to the flammable solvent, resulting spray characteristics, flame shape and appearance are changed in color, shape and mean droplet size distribution. Compared to resulting mean droplet sizes of pure solvent mixtures (D32, 22 μm), mean droplet sizes in the center of the precursor flame at 30 mm above the burner are generally smaller (D32, 18 μm). Persisting high share of small droplets in the droplet size distribution are presented, that presumably origin from an accumulation of metal organic precursor at the droplet surface during combustion, that acts as a diffusive barrier for high volatility solvent and thus reduces droplet evaporation. Sufficiently high above the nozzle exit, increasing the precursor concentration does not affect the radial distribution of mean droplet sizes but leads to increased mean particle sizes. More precursor presumably leads to higher concentrations of prime particles in the flame, thus probability of particle collusion and agglomeration. High-speed imaging at nozzle exit revealed random fluctuations of initial jet diameter, paired with jet axis shifting around 1000 Hz. These superposed fluctuations determine the initial conditions for atomization, induce pulsations in the flame and thus initiate the entire chain of the particle synthesis process.","lang":"eng"}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":2807339,"file_name":"Influence of precursor concentration on spray and particle.pdf","access_level":"closed","file_id":"25056","date_updated":"2021-09-28T08:39:12Z","creator":"ricardo","date_created":"2021-09-28T08:39:12Z"}],"status":"public","_id":"24502","user_id":"67002","ddc":["620"],"keyword":["FSP","nanoparticle synthesis","in situ measurements"],"file_date_updated":"2021-09-28T08:39:12Z","language":[{"iso":"eng"}],"publication_status":"published","has_accepted_license":"1","year":"2019","citation":{"apa":"Bieber, M., Tischendorf, R., Reddemann, M., Schmid, H.-J., &#38; Kneer, R.

Of particular importance in practical scenarios is the need to consider collaboration of rescue units. This task has hardly been addressed in the literature. We contribute to both modeling and solving this problem by (1) conceptualizing the situation as a type of scheduling problem, (2) modeling it as a binary linear minimization problem, (3) suggesting a branch-and-price algorithm, which can serve as both an exact and heuristic solution procedure, and (4) conducting computational experiments - including a sensitivity analysis of the effects of exogenous model parameters on execution times and objective value improvements over a heuristic suggested in the literature - for different practical disaster scenarios. The results of our computational experiments show that most problem instances of practically feasible size can be solved to optimality within ten minutes. Furthermore, even when our algorithm is terminated once the first feasible solution has been found, this solution is in almost all cases competitive to the optimal solution and substantially better than the solution obtained by the best known algorithm from the literature. This performance of our branch-and-price algorithm enables rescue organizations to apply our procedure in practice, even when the time for decision making is limited to a few minutes. By addressing a very general type of scheduling problem, our approach applies to various scheduling situations.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_name":"JOURNAL VERSION.pdf","access_level":"open_access","file_id":"6019","file_size":1470310,"date_created":"2018-12-07T11:13:12Z","creator":"hsiemes","date_updated":"2018-12-13T15:16:37Z"}],"publication":"European Journal of Operational Research","title":"An Exact Branch-and-Price Algorithm for Scheduling Rescue Units during Disaster Response","publisher":"Elsevier","date_created":"2018-11-14T15:35:27Z","year":"2019","issue":"1"},{"year":"2019","page":"65","citation":{"ieee":"J.
