Abstract An emerging trend in smart manufacturing of the future is robotic additive manufacturing or 3D printing which introduces numerous advantages towards fast and efficient printing of high-quality customized products. In the case of the construction industry, and specifically in large-scale settings, multi-robotic additive manufacturing (i.e., adopting a team of 3D printer robots) has been found to be a promising solution in order to overcome the existing size limitations. Consequently, several research efforts regarding the development and control of such robotic additive manufacturing solutions have been reported in the literature. However, given the increasing environmental concerns, establishing novel methodologies for energy-efficient processing and planning of these systems towards higher sustainability is necessary. This paper presents a novel framework towards energy-efficient multi-robotic additive manufacturing and describes the overall challenges with respect to the energy efficiency. The energy module of the proposed framework is implemented in a simulation environment. In addition, a systematic approach for energy-aware robot positioning is introduced based on the novel concept of reciprocal energy map. The reciprocal energy map is established based on the original energy map calculated by the energy module and can be used for identifying the low energy zones for positioning and relocation of robots during the printing process.

AbstractIn the wake of the COVID-19 pandemic, physical distancing behavior turned out to be key to mitigating the virus spread. Therefore, it is crucial that we understand how we can successfully alter our behavior and promote physical distancing. We present a framework to systematically assess the effectiveness of behavioral interventions to stimulate physical distancing. In addition, we demonstrate the feasibility of this framework in a large-scale natural experiment (N = 639) conducted during an art fair. In an experimental design, we varied interventions to evaluate the effect of face masks, walking directions, and immediate feedback on visitors’ contacts. We represent visitors as nodes, and their contacts as links in a contact network. Subsequently, we used network modelling to test for differences in these contact networks. We find no evidence that face masks influence physical distancing, while unidirectional walking directions and buzzer feedback do positively impact physical distancing. This study offers a feasible way to optimize physical distancing interventions through scientific research. As such, the presented framework provides society with the means to directly evaluate interventions, so that policy can be based on evidence rather than conjecture.

Abstract The present paper offers a first systematic approach to the expression of impersonal human reference in French Sign Language (LSF). It extends and deepens a prior study carried out by the authors on the basis of a large scale discourse corpus. The description proposed here is based primarily on data elicited through a specialised questionnaire on impersonal human reference (Barberà & Cabredo Hofherr, this volume), initially developed for spoken languages and adapted for sign languages. The strategies revealed are compared with those discussed in our prior study. We begin with a brief review of the literature on impersonal human reference in spoken and sign languages, and a presentation of our theoretical framework for the analysis of LSF. We then elaborate on our methodology and the issues raised by the elicitation protocol adopted, from initial stages of its preparation to the representation of our data. We finally present and discuss the main strategies we highlighted for the expression of impersonal reference in LSF.

Causes Of Failure

When a researcher tests an educational program, product, or policy in a randomized controlled trial and detects a significant effect on an outcome, the intervention is usually classified as something that “works.” When expected effects are not found, there is seldom an orderly and transparent analysis of plausible reasons why. Accumulating and learning from possible failure mechanisms is not standard practice in education research, and it is not common to design interventions with causes of failure in mind. This chapter develops Boruch and Ruby’s proposition that the education sciences would benefit from a systematic approach to the study of failure. We review and taxonomize recent reports of large-scale randomized controlled trials in K–12 schooling that yielded at least one null or negative major outcome, including the nature of the event and reasons (if provided) for why it occurred. Our purpose is to introduce a broad framework for thinking about educational interventions that do not produce expected effects and seed a cumulative knowledge base on when, how, and why interventions do not reach expectations. The reasons why an individual intervention fails to elicit an outcome are not straightforward, but themes emerge when researchers’ reports are synthesized.

Effective Design

The sense of touch enables us to safely interact and control our contacts with our surroundings. Many technical systems and applications could profit from a similar type of sense. Yet, despite the emergence of e-skin systems covering more extensive areas, large-area realizations of e-skin effectively boosting applications are still rare. Recent advancements have improved the deployability and robustness of e-skin systems laying the basis for their scalability. However, the upscaling of e-skin systems introduces yet another challenge—the challenge of handling a large amount of heterogeneous tactile information with complex spatial relations between sensing points. We targeted this challenge and proposed an event-driven approach for large-area skin systems. While our previous works focused on the implementation and the experimental validation of the approach, this work now provides the consolidated foundations for realizing, designing, and understanding large-area event-driven e-skin systems for effective applications. This work homogenizes the different perspectives on event-driven systems and assesses the applicability of existing event-driven implementations in large-area skin systems. Additionally, we provide novel guidelines for tuning the novelty-threshold of event generators. Overall, this work develops a systematic approach towards realizing a flexible event-driven information handling system on standard computer systems for large-scale e-skin with detailed descriptions on the effective design of event generators and decoders. All designs and guidelines are validated by outlining their impacts on our implementations, and by consolidating various experimental results. The resulting system design for e-skin systems is scalable, efficient, flexible, and capable of handling large amounts of information without customized hardware. The system provides the feasibility of complex large-area tactile applications, for instance in robotics.
