Supporting teamwork in hybrid multi-team systems

Multi-level human-autonomy teaming in a distributed mission context consists of multiple manned and unmanned systems that require flexible decision making authority. We introduce the notion of ‘hybrid multi-team systems’ to refer to multiple teams consisting of n-number of humans and n-number of semi-autonomous agents having interdependence...

On the graphical stability of hybrid solutions with non-matching jump times

We investigate stability of a solution of a hybrid system in the sense that the graphs of solutions from nearby initial conditions remain close and tend towards the graph of the given solution. In this manner, a small continuous-time mismatch is allowed between the jump times of neighbouring solutions and the ‘peaking phenomenon’ is avoided. We...

Hybrid systems with state-triggered jumps: sensitivity-based stability analysis with application to trajectory tracking

Magnetic field resilient superconducting coplanar waveguide resonators for hybrid cQED experiments

Superconducting coplanar-waveguide resonators that can operate in strong magnetic fields are important tools for a variety of high-frequency superconducting devices. Magnetic fields degrade resonator performance by creating Abrikosov vortices that cause resistive losses and frequency fluctuations or suppress the superconductivity entirely. To...

Functions of the CCCH type zinc finger protein OsGZF1 in regulation of the seed storage protein GluB-1 from rice

Glutelins are the most abundant storage proteins in rice grain and can make up to 80 % of total protein content. The promoter region of GluB-1, one of the glutelin genes in rice, has been intensively used as a model to understand regulation of seed-storage protein accumulation. In this study, we describe a zinc finger gene of the Cys3His1 (CCCH...

Hybrid-impulsive second order sliding mode control: Lyapunov approach

A perturbed nonlinear system of relative degree two controlled by discontinuous-impulsive feedbacks is studied. The hybrid-impulsive terms serve to drive instantaneously the system trajectories to the origin or to its small vicinity. In particular, impulsive-twisting control exhibits an uniform exact finite time convergence to the second order...

System design for distributed adaptive observation systems

Currently, there is no clear-cut approach or design methodology available for designing distributed adaptive observation systems, partly due to the necessity to combine elements and approaches from several technological and scientific communities. Recently, an effort was made addressing this issue in an integrated manner, resulting in the...

Adjoint analysis of mixed continuous/discrete systems in simulink

The adjoint simulation method is a well established and efficient tool for gaining insight and understanding of key parameters affecting the behaviour and performance of a guided missile homing system. Traditionally, the method has been employed by various missile companies during the preliminary and conceptual stages of new missile programs. A...

Organizing smart networks and humans into augmented teams

This paper discusses the challenge of turning networks of sensors, computers, agents and humans into hybrid teams that are capable, effective and adaptive. We propose a functional model and illustrate how such a model can be put into practice, and augment the capabilities of the human organization. We specifically focus on the interaction...

On event based state estimation

To reduce the amount of data transfer in networked control systems and wireless sensor networks, measurements are usually taken only when an event occurs, rather than at each synchronous sampling instant. However, this complicates estimation and control problems considerably. The goal of this paper is to develop a state estimation algorithm that...

Augmented Teams -- Assembling Smart Sensors, Intelligent Networks and Humans into Agile Task Groups

Safety and security environments are full of networked devices. Despite ample research on sensor networks and network technology, there is little practical comprehensive work on how to incorporate such technologies effectively into human-centered teams. This paper discusses the challenge of assembling networks of smart sensors, systems and...

Designing Networked Adaptive Interactive Hybrid Systems

Advances in network technologies enable distributed systems, operating in complex physical environments, to coordinate their activities over larger areas within shorter time intervals. In these systems humans and intelligent machines will, in close interaction, be able to reach their goals under changing situations. To moderate the design of...

Algebraic software analysis and embedded simulation of a driving robot

At TNO Automotive the Generic Driving Actuator (GDA) is developed. The GDA is a device capable of driving a vehicle fully automatically using the same interface as a human driverdoes. In this paper, the design of the GDA is discussed. The software and hardware of the GDA and its effect on vehicle behaviour are analyzed from a safety point of...
