Ultrasound for Data Transfers from Deep Implants: an Experimental Comparison Between Binary-Frequency-Shift-Keying and On-Off-Keying with Backscatter Modulation

Implantable devices need to communicate information to the outside world. For deep-seated miniaturized implants ultrasound communication can be favourable. However, implants need to operate during movement, and the selected communication scheme should be assessed accordingly. In this work, we implemented a simple protocol to transfer data...

FedKNOW: Federated Continual Learning with Signature Task Knowledge Integration at Edge

Deep Neural Networks (DNNs) have been ubiquitously adopted in internet of things and are becoming an integral of our daily life. When tackling the evolving learning tasks in real world, such as classifying different types of objects, DNNs face the challenge to continually retrain themselves according to the tasks on different edge devices....

Two for the price of one: communication efficient and privacy-preserving distributed average consensus using quantization

Both communication overhead and privacy are main concerns in designing distributed computing algorithms. It is very challenging to address them simultaneously as encryption methods required for privacy-preservation often incur high communication costs. In this paper, we argue that there is a fundamental link between communication efficiency...

Signs and symbols of the domestic façade in the city: Changes, confusion or decline?

In a time in which 50% of the world inhabitants live in an urban context, a percentage that will definitely even grow, it is important to ask whether the residential building within daily public and anonymous city life still has the quality of privacy and identity of a ‘home’. The on-going PhD research “The façade as an intermediary element...

Does sketching stand alone as a communication tool during concept generation in design teams?

The present study investigates the relation between sketching and communication in teams during the idea generation process in early concept generation. A quasi-experiment study has been conducted with Masters students of Industrial Design Engineering at Delft University of Technology, Netherlands. Six groups consisting of three students had to...

Multi-disciplinary design optimisation via dashboard portals

This paper will present the opportunities a dashboard-based system provides to gather information on alternatives and display this in such a way that it will help the user making decisions by making use of multi-disciplinary optimisation (MDO) technology. The multi-disciplinary set up of the program will enable the user to understand the...

Postboard: Free-form tangible messaging for people with aphasia (and other people)

In this paper we report the design of a communication system for people with aphasia. It consists of pairs of physical whiteboards that are connected over the internet. This allows users to combine any personal language skills with visuals and already existing materials at hand. The design has been based on feedback and evaluation sessions with...

Characterizing Network Architecture for Inter-satellite Communication and Relative Navigation in Precise Formation Flying

Precise formation flying (PFF) missions require formation acquisition and maintenance through interactions among spacecraft by inter-satellite communication and relative navigation. That requires the network architecture to satisfy dedicated system constraints of time-criticality for updating navigation measurements and flexibility for...

The effects of a Task facilitating Working Environment on office space use, communication, concentration, collaboration, privacy and distraction
