TY - JOUR A1 - Fischer, Markus A1 - Michalk, Wibke A1 - Hardt, Cornelius A1 - Bogenberger, Klaus T1 - Bill It Right: Evaluating Public Charging Station Usage Behavior under the Presence of Different Pricing Policies JF - World Electric Vehicle Journal N2 - This study investigates for the first time how public charging infrastructure usage differs under the presence of diverse pricing models. About 3 million charging events from different European countries were classified according to five different pricing models (cost-free, flat-rate, time-based, energy-based, and mixed) and evaluated using various performance indicators such as connection duration; transferred energy volumes; average power; achievable revenue; and the share of charging and idle time for AC, DC, and HPC charging infrastructure. The study results show that the performance indicators differed for the classified pricing models. In addition to the quantitative comparison of the performance indicators, a Kruskal–Wallis one-way analysis of variance and a pairwise comparison using the Mann–Whitney-U test were used to show that the data distributions of the defined pricing models were statistically significantly different. The results are discussed from various perspectives on the efficient design of public charging infrastructure. The results show that time-based pricing models can improve the availability of public charging infrastructure, as the connection duration per charging event can be roughly halved compared to other pricing models. Flat-rate pricing models and AC charging infrastructure can support the temporal shift of charging events, such as shifting demand peaks, as charging events usually have several hours of idle time per charging process. By quantifying various performance indicators for different charging technologies and pricing models, the study is relevant for stakeholders involved in the development and operation of public charging infrastructure.

This is in some sense rather surprising, because low-discrepancy sequences always have β-Poissonian pair correlations for all 0<β<1/d and are therefore arbitrarily close to having Poissonian pair correlations (which corresponds to the case β=1/d). In this paper, we further elaborate on the closeness of the two notions. We show that d-dimensional Kronecker sequences for badly approximable vectors α→ with an arbitrary small uniformly distributed stochastic error term generically have β=1/d-Poissonian pair correlations.

However, process mining has only half-heartedly pursued this line of development. In particular, the well-founded results of interdisciplinary social network analysis have hardly been taken up. This article shows how the explanation and design of the phenomenon "organization" can benefit from the further development of this network view of business processes. To this end, the basic idea of social process networks is presented and the current state of research is outlined. Furthermore, social networks are presented as a new component of organization design. An interesting, far-reaching new field of research is expected. This paper presents three novel findings that could be the starting point for further research, but can also be used in practice today.

The adhesive tapes under test are implemented as signal return paths in microstrip lines. Changes in the ground plane impedance by adhesive deterioration are analyzed by S-parameter measurements from 1MHz to 3GHz. A circuit model for contact impedance degradation is proposed and applied in simulation of board level shielding. Contact resistance and contact capacitance are found to increase significantly after 2400h, causing a declined magnetic field shielding effectiveness by 30 dB below 500 MHz.

Here, we examined this forward testing effect in children’s spatial memory. Kindergartners (5–6 years) and younger (7–8 years) and older (9–10 years) elementary school children studied four successively presented 3 x 3 arrays, each composed of the same 9 objects. The children were asked to memorize the locations of the objects that differed across the four arrays. Following presentation of each of the first three arrays, memory for the object locations of the respective array was tested (testing condition) or the array was re-presented for additional study (restudy condition). Results revealed that testing Arrays 1 to 3 enhanced children’s object location memory for Array 4 relative to restudying. Moreover, children in the testing condition were less likely to confuse Array 4 locations with previous locations, suggesting that testing reduces the buildup of proactive interference. Both effects were found regardless of age. Thus, the current findings indicate that testing is an effective means to resolve proactive interference and, in this way, to enhance children’s learning and remembering of spatial information even before the time of school entry.

Migratory movements from the territory of the former Ottoman Empire to the Americas, specifically to Brazil, and 2. transregional migration between different regions within China. On the basis of empirical data, we discuss sociological biographical research as an approach to analyzing migration and social mobility as transgenerational processes. In the case of Syrians in Brazil who have fled from the civil war, these processes are reflected in transnational family structures, transgenerational mandates, and knowledge transmission. In the case of domestic migration within China, the “mission” that families give their children is social advancement through education (e.g., Crabb 2010; Fong 2004). In the context of anti-Western discourses in China, it can be demonstrated that postcolonial discourses are functional in the effort to regain former international strength and national prosperity, and that discourses on “becoming a modern citizen” pervade family aspirations. The article is intended as a plea for i) taking a closer look at historical and contemporary South-South relations, and ii) situating current migration movements historically. It ties into global historical and sociological debates on “shared/common histories” and “intertwined histories."

This modulation is accomplished by coherent switching of the short circuit current induced in a third loop. An analytical circuit model supporting the design for future time-modulated IPT systems is derived. We demonstrate an increase in load rms-voltage by 13% (28% gain in power) compared to an unmodulated transfer on an experimental system operating at fundamental frequencies ranging from 40kHz to 500kHz.

First results of the mixed-methods process evaluation T2 - 7. Forschungssymposium Physiotherapie N2 - BACKGROUND Vertigo, dizziness or balance disorders (VDB) affect the mobility and participation of many older people and are also one of the most frequent reasons for visiting the general practitioner's (GP) practice due to multifactorial causes. Physiotherapy (PT) can be crucial for the complex care of people with VDB but is rarely prescribed by GPs. So we developed an evidence-based, multidisciplinary care pathway as a complex intervention following the UK Medical Research Council guideline, which was piloted and is now being evaluated for effectiveness, accompanied by a process evaluation. METHOD The care pathway of the multicentre cluster-RCT (MobilE-PHY2) included decision aids and training for PTs and GPs in the intervention group and optimised standard care in the control group. A mixed-methods process evaluation following Grant’s framework for designing process evaluations examined barriers, facilitating factors and mechanisms of impact in recruiting and reaching participants, implementing the intervention and the response of all participants. Therefore, a logic model was developed illustrating the relationship between the planned work to implement the intervention, the expected mechanism of impact (based on the behaviour change wheel as a change theory), the intended results (output, outcome and impact), and categories of possible influencing factors. The underlying assumption is that a behavioural change in PT and GP is a prerequisite for a change in patient behaviour, which can lead to improved mobility and participation (outcome of MobilE-PHY2). Guided interviews were conducted with patients before the intervention and after six months and with PTs and GPs after six months. Additionally, the training evaluations, completed decision aids and structural questionnaires will be analysed from June 2023. RESULTS AND CONCLUSION At one study site, a total of 37 patients, 17 PTs and nine GPs were included. Interviews were conducted with 16 patients, six PTs and GPs. In the intervention group, 12 PTs and 18 GPs completed decision aids, 13 PTs and two GPs completed evaluation forms, and eight PTs and four GPs completed structural data. The preliminary results of the process evaluation will be reported at the Congress. The results are intended to give indications for a broad implementation of the care pathway, including and promoting physiotherapy and therefore contributing to improved evidence-based healthcare for older people with VDB.

Orthogonally placed switchable short circuit loops are added in order to modulate the wave propagation properties of the MIW structure without changing the resonance frequency. We derive an analytical model based on lumped circuit analysis for the MIW waveguide and successfully evaluate the theoretical findings by circuit modeling and field simulation. We demonstrate switchable, i.e. addressable, guided wireless power transfer along an experimental MIW structure at a resonance frequency of 20.5 MHz.
