Robotic Skill Mutation in Robot-to-Robot Propagation During a Physically Collaborative Sawing Task

Maessen, Rosa E.S. (author), Prendergast, J.M. (author), Peternel, L. (author)

Skill propagation among robots without human involvement can be crucial in quickly spreading new physical skills to many robots. In this respect, it is a good alternative to pure reinforcement learning, which can be time-consuming, or learning from human demonstration, which requires human involvement. In the latter case, there may not be...

The role of prototyping and co-creation in circular economy-oriented innovation: A longitudinal case study in the kitchen industry

Dokter, Giliam (author), Boks, Casper (author), Rahe, Ulrike (author), Jansen, B. (author), Hagejärd, Sofie (author), Thuvander, Liane (author)

To bridge the gap between the conceptualisation and implementation of circular value propositions, recent research efforts have focused on linking design-driven approaches with circular-oriented innovation. Such approaches can facilitate iterative processes that emphasise co-creation, prototyping, and real-life experimentation, ultimately...

Mean Field Behavior of Collaborative Multiagent Foragers

Jarne Ornia, D. (author), Zufiria, Pedro J. (author), Mazo, M. (author)

Collaborative multiagent robotic systems, where agents coordinate by modifying a shared environment often result in undesired dynamical couplings that complicate the analysis and experiments when solving a specific problem or task. Simultaneously, biologically inspired robotics rely on simplifying agents and increasing their number to obtain...

The ground handler dock capacitated pickup and delivery problem with time windows: A collaborative framework for air cargo operations

Bombelli, A. (author), Fazi, S. (author)

We study a typical problem within the air cargo supply chain, concerning the transportation of standard Unit Load Devices (ULDs) from freight forwarders’ to ground handlers’ warehouses. First, ULDs are picked up by a set of available trucks at the freight forwarders’ premises within a time window. Next, they are delivered to the ground handlers,...

Social-aware Federated Learning: Challenges and Opportunities in Collaborative Data Training

Ottun, Abdul Rasheed (author), Mane, Pramod C. (author), Yin, Zhigang (author), Paul, Souvik (author), Liyanage, Mohan (author), Pridmore, Jason (author), Ding, Aaron Yi (author), Sharma, Rajesh (author), Nurmi, Petteri (author), Flores, Huber (author)

Federated learning (FL) is a promising privacy-preserving solution to build powerful AI models. In many FL scenarios, such as healthcare or smart city monitoring, the user's devices may lack the required capabilities to collect suitable data, which limits their contributions to the global model. We contribute social-aware federated learning...

MPC-based Haptic Shared Steering System: A Driver Modeling Approach for Symbiotic Driving

Rios Lazcano, A.M. (author), Niu, Tenghao (author), Carrera Akutain, Xabier (author), Cole, David (author), Shyrokau, B. (author)

Advanced Driver Assistance Systems (ADAS) aim to increase safety and reduce mental workload. However, the gap in the understanding of the closed-loop driver-vehicle interaction often leads to reduced user acceptance. In this study, an optimal torque control law is calculated online in the Model Predictive Control (MPC) framework to guarantee...

Economies of scale and sustainability in local government: A complex issue

Blank, J.L.T. (author), Niaounakis, T.K. (author)

Local governments may seek efficient public service delivery through scaling up production, and the quest for the optimal local government size has attracted extensive attention of scholars and policy makers. Indeed, if scale matters for local government efficiency, increasing size may be a key factor in achieving more value for money for...

Towards automatic collaboration analytics for group speech data using learning analytics

Praharaj, S. (author), Scheffel, Maren (author), Schmitz, Marcel (author), Specht, M.M. (author), Drachsler, Hendrik (author)

Collaboration is an important 21st Century skill. Co-located (or face-to-face) collaboration (CC) analytics gained momentum with the advent of sensor technology. Most of these works have used the audio modality to detect the quality of CC. The CC quality can be detected from simple indicators of collaboration such as total speaking time or...

A process model for collaboration in circular oriented innovation

Brown, P.D. (author), Von Daniels, C. (author), Bocken, N.M.P. (author), Balkenende, R. (author)

Circular oriented innovation commonly requires collaboration. Yet, to date, circular research lacks empirical investigation into collaborative processes. Collaborative processes are, however, highly researched within strategic management literature, thus offering valuable insights. The purpose of this paper is to investigate, identify and...
