Toward Science-Based and Knowledge-Based Targets for Global Sustainable Resource Use
(2019-08-06)
The article discusses key aspects to be considered for the orientation of sustainable resource policies. Resource management at the local scale needs to be supplemented by governmental action in order to adjust production and consumption toward acceptable levels of global resource use. What is acceptable is being informed by scientific findings on environmental degradation and relevant cause–effect relationships. However, the desired state of the environment, the tolerable level of uncertainties about environmental ...

Control of Jump Markov Uncertain Linear Systems With General Probability Distributions
(2022-02-25)
This paper introduces a method to control a class of jump Markov linear systems with uncertain initialization of the continuous state and affected by disturbances. Both types of uncertainties are modeled as stochastic processes with arbitrarily chosen probability distributions, for which however, the expected values and (co-)variances are known. The paper elaborates on the control task of steering the uncertain system into a target set by use of continuous controls, while chance constraints have to be satisfied for ...

An engineering perspective on the numerics of quasi-periodic oscillations
(2022-04-29)
The phenomenon of quasi-periodicity in deterministic dynamical systems describes stationary solutions, which neither exhibit a finite period length nor are chaotic. Recently, an increasing demand for robust numerical methods is driven by applied dynamics and industrial applications. In this context, direct time integration proves to be impractical due to extensive integration intervals. Therefore, in a first step, this contribution aims on giving an application oriented survey of the basic theory as well as alternative ...

Design based on availability: Generative design and robotic fabrication workflow for non-standardized sheet metal with variable properties
(2022-03-07)
This paper presents the use of a computational design algorithm in combination with robotic fabrication and sensing to augment the design and construction process for non-standardized material. Although reusing reclaimed material can significantly reduce the environmental impact in building construction, current design processes are not set up for this shift in thinking. Contrary to conventional practices, designing within the constraints of available material means that geometry and topology cannot be fully ...

The Role of Just World Beliefs in Responding to the COVID-19 Pandemic
(2022-02-17)
This study investigated whether people’s personal belief in a just world (BJW) is linked to their willingness to physically distance themselves from others during the COVID-19 pandemic. Past research found personal BJW to be positively related to prosocial behavior, justice striving, and lower risk perceptions. If social distancing reflects a concern for others, high personal BJW should predict increased interest in social distancing. If social distancing reflects a concern for one’s personal risk, high personal BJW ...

The confidence-accuracy relation – A comparison of metacognition measures in lie detection
(2022-04-26)
Previous research has produced mixed results on the question of whether confidence in ad hoc veracity judgments can be used as an indicator of judgment accuracy. These studies have used a variety of measures to analyze the confidence-accuracy relationship; however, they have rarely explicitly addressed why a particular measure was chosen and what its properties are. We theoretically and empirically examined previously used measures of metacognition in lie detection and report the results these measures yielded in ...

Are open-book tests still as effective as closed-book tests even after a delay of 2 weeks?
(2022-04-06)
The present work was conducted to re-examine the findings of Agarwal et al. (Applied Cognitive Psychology, 22(7), 861–876, 2008), which showed that both closed-book tests (with feedback) and open-book tests increased learning outcomes after 1 week compared to simple re-study of the same materials. However, contrary to often found benefits of retrieval practice—which should be more pronounced in closed-book tests—both test conditions proved to be similarly effective. As retrieval practice benefits increase with retention ...

Body scan meditation enhances the autonomous sensory meridian response to auditory stimuli
(2022-05-03)
Autonomous sensory meridian response (ASMR) is a pleasant, tingling sensation on the skin that can be elicited by certain auditory and visual stimuli, with the intertwining of sensory modalities and emotional reactions observable in this phenomenon resembling that of synesthesia. The current study shows that the perception of ASMR-associated tingles can be enhanced by means of a prior mindfulness exercise in which attention is drawn to the body. This finding contributes to a better understanding of the crossmodal ...

3DWoodWind: robotic winding processes for material-efficient lightweight veneer components
(2022-03-25)
Winding processes are known from fiber composite technology for highly resistance lightweight components for aviation. These fiber-based processes work predominantly with synthetic composites made of carbon or glass fibers. For the construction industry, these additive processes are very promising and resource-efficient building processes, but they are still hardly used in timber construction despite the very high level of digitalization and technical development. The 3DWoodWind research project uses a continuous ...

Stream-based active learning for sliding windows under the influence of verification latency
(2021-11-18)
Stream-based active learning (AL) strategies minimize the labeling effort by querying labels that improve the classifier’s performance the most. So far, these strategies neglect the fact that an oracle or expert requires time to provide a queried label. We show that existing AL methods deteriorate or even fail under the influence of such verification latency. The problem with these methods is that they estimate a label’s utility on the currently available labeled data. However, when this label would arrive, some of ...
