Solution Space Concept for Trajectory-Based Air Traffic Control: An Ecological Approach

Klomp, R.E. (author)

THE increasing demand in worldwide air travel is foreseen to push the limits of capacity of the current Air TrafficManagement (ATM) system within the coming decade. Therefore, twomajor international programs have been initiated to fundamentally restructure the way in which Air Traffic Control (ATC) is performed. A key pillar in both programs is...

Ramp Metering with Microscopic Gap Detection Algorithm Design and Empirical Acceleration Verification

Klomp, Stefan R. (author), Knoop, V.L. (author), Taale, Henk (author), Hoogendoorn, S.P. (author)

Freeway on-ramp areas are susceptible to traffic congestion during peak hours. To delay or prevent the onset of congestion, ramp metering can be applied. A Ramp Metering Installation (RMI) controls the inflow from the on-ramp to the main line so that the total flow can be kept just below capacity. Current ramp metering algorithms apply...

Validating SuperHuman Automated Driving Performance

Ajanovic, Zlatan (author), Klomp, Matthijs (author), Lacevic, Bakir (author), Shyrokau, B. (author), Pretto, Paolo (author), Islam, Hassaan (author), Stettinger, Georg (author), Horn, Martin (author)

Closed-loop validation of autonomous vehicles is an open problem, significantly influencing development and adoption of this technology. The main contribution of this paper is a novel approach to reproducible, scenario-based validation that decouples the problem into several sub-problems, while avoiding to brake the crucial couplings. First,...

Loss of selective wrist muscle activation in post-stroke patients

van der Krogt, Hanneke (author), Kouwijzer, Ingrid (author), Klomp, A. (author), Meskers, Carel G.M. (author), Arendzen, J. Hans (author), de Groot, Jurriaan H. (author)

Purpose: Loss of selective muscle activation after stroke contributes to impaired arm function, is difficult to quantify and is not systematically assessed yet. The aim of this study was to describe and validate a technique for quantification of selective muscle activation of wrist flexor and extensor muscles in a cohort of post-stroke...

Exploring the potential benefits of multi-aircraft trajectory manipulation in future air traffic control

Nagaraj, R. (author), Klomp, R.E. (author), Borst, C. (author), van Paassen, M.M. (author), Mulder, Max (author)

Future Air Traffic Management is expected to shift towards four dimensional trajectory (4DT) management, requiring new decision support tools for air traffic controllers to meet stringent time and position constraints. In previous work, a prototype human-machine interface has been developed for 4D trajectory manipulations of single aircraft....

Flow-based air traffic control: Human-machine interface for steering a path-planning algorithm

Ten Brink, D. S.A. (author), Klomp, R.E. (author), Borst, C. (author), van Paassen, M.M. (author), Mulder, Max (author)

In the near future, air traffic controllers are expected to adhere to stringent time and position constraints in controlling traffic. For this new task, new decision-support tools are required which include higher levels of automation, whilst letting humans remain to be the ultimate responsible for the safety of operations. In previous...

Solution space concept: Human-machine interface for 4D trajectory management

Klomp, R.E. (author), Riegman, R. (author), Borst, C. (author), Mulder, Max (author), van Paassen, M.M. (author)

The current evolution of the ATM system, led by the SESAR programme in Europe and the NextGen programme in the US, is foreseen to bring a paradigm shift to the work of the air traffic controller. Rather than the current primarily tactical control method, one aims for the introduction of more strategic, 4D (space and time) trajectory...

An approach to develop haptic feedback control reference for steering systems using open-loop driving manoeuvres

Chugh, T. (author), Bruzelius, F. (author), Klomp, M. (author), Shyrokau, B. (author)

In this paper, a methodology to capture the model-based haptic feedback control reference for closed-loop steering systems is demonstrated. The parameterisation is based on the measurements of open-loop driving manoeuvres for the inertia-spring-damper-friction reference model. The steady-state and transient manoeuvres are used to identify the...

Design of haptic feedback control for Steer-by-Wire

Chugh, T. (author), Bruzelius, Fredrik (author), Klomp, Matthijs (author), Shyrokau, B. (author)

This paper illustrates a comparison of different haptic feedback control strategies; primarily focusing on open and closed-loop methods for a Force-Feedback Steer-by-Wire system. Due to shortcomings caused by the feedback motor impedance in the open loop architecture, the tracking performance is deteriorated. Consequently it is shown that the...

Design of an Ecological Flow-based Interface for 4D Trajectory Management in Air Traffic Control

Pinto, J. (author), Klomp, R.E. (author), Borst, C. (author), Van Paassen, M.M. (author), Mulder, M. (author)

The concept of trajectory-based operations as proposed by SESAR and NextGen seeks to increase airspace efficiency and capacity by introducing time as an explicit control variable. Such form of operations lean heavily on the introduction of higher levels of automation to support the human air traffic controller in performing this new task. In...

Linear Identification of Nonlinear Wrist Neuromechanics in Stroke

Klomp, A. (author)

In many stroke patients, a motor cortex lesion alters motor control. Initially, paresis is most prominent, but then over time, joint stiffening and hyperreflexia may occur. How these different disorders develop over time is still unknown due to high system complexity. Secondary changes in the corticospinal tract, peripheral biomechanics and...

Comprehensive neuromechanical assessment in stroke patients: Reliability and responsiveness of a protocol to measure neural and non-neural wrist properties

Background: Understanding movement disorder after stroke and providing targeted treatment for post stroke patients requires valid and reliable identification of biomechanical (passive) and neural (active and reflexive) contributors. Aim of this study was to assess test-retest reliability of passive, active and reflexive parameters and to...

The gap between clinical gaze and systematic assessment of movement disorders after stroke

Van der Krogt, H.J.M. (author), Meskers, C.G.M. (author), De Groot, J.H. (author), Klomp, A. (author), Arendzen, J.H. (author)

Background: Movement disorders after stroke are still captured by clinical gaze and translated to ordinal scores of low resolution. There is a clear need for objective quantification, with outcome measures related to pathophysiological background. Neural and non-neural contributors to joint behavior should be separated using different...

Re-design of an Inbound Planning Interface for Air Traffic Control

Klomp, R.E. (author), Mulder, M. (author), Van Paassen, M.M. (author), Roerdink, M.I. (author)

In the coming decades, the task of an air traffic controller is expected to shift to one of strategic, trajectorybased air traffic management. This form of air traffic control is no longer possible without the help of automated support tools. In previous research, it has been shown that the time-space diagram, combined with a conventional plan...

Chapter 1 is a review on homogeneous transfer hydrogenations. It shows the different reaction mechanisms involved for different types of catalysts. Additionally, the importance of the right choice of hydrogen donors and solvents is discussed. A wide range of compounds can be reduced in this way and the selectivity of these catalysts is very high...
