Comparing the Active, Functional, and Passive Range of Motion of Finger Joints Using Dynamic Measurement

Yuan, Tianyun (author), Song, Yu (author), Goossens, R.H.M. (author), Kraan, G.A. (author)

Studies on finger kinematics, especially the range of motion (RoM) measurements, are essential to understand the use of finger joints and the pathology of related disease. Limited literatures compared the active RoM (A-RoM) of finger joints with either their functional RoM (F-RoM) or passive RoM (p-RoM) using different measuring protocols and...

Identify Finger Rotation Angles With ArUco Markers and Action Cameras

Yuan, T. (author), Song, Y. (author), Kraan, G.A. (author), Goossens, R.H.M. (author)

Measuring the motions of human hand joints is often a challenge due to the high number of degrees-of-freedom. In this study, we proposed a hand tracking system utilizing action cameras and ArUco markers to continuously measure the rotation angles of hand joints during motion. Three methods were developed to estimate the joint rotation angles....

Jumping to a better world: An agent-based exploration of criticality in low-carbon energy transitions

Kraan, O.D.E. (author), Dalderop, Steven (author), Kramer, G.J. (author), Nikolic, I. (author)

Understanding the possible transition pathways of the energy system requires the integration of human behaviour in energy system models. In order to model the influence of actor behaviour we have developed ACT (Agent-Based Model of Critical Transitions), an agent-based model inspired by an existing conceptualisation of critical transitions....

Why fully liberalised electricity markets will fail to meet deep decarbonisation targets even with strong carbon pricing

Kraan, Oscar (author), Kramer, Gert Jan (author), Nikolic, I. (author), Chappin, E.J.L. (author), Koning, Vinzenz (author)

Full decarbonisation of the electricity system is one of the key elements to limit global warming. As this transition takes place, the electricity system must maintain system adequacy and remain affordable to consumers. In liberalised electricity markets investors are seen as key actors driving this transition. Due to the intermittent...

Algorithm of the Computer Modelling and a SESANS Setup with Adiabatic RF-Flippers

Kraan, W.H. (author), Zabenkin, V.N. (author), Axelrod, LA (author), Chetverikov, Yu.O. (author), Grigoriev, SV (author), Yashina, E.G. (author), Sumbatyan, A.A. (author)

We made software to simulate Larmor precession in a setup for SESANS with adiabatic/RF flippers in magnets, existing at PNPI. The final polarisation of a divergent “ribbon beam” of height 2 cm is calculated as a function of λ. For λ= 6 A, flippers 56 cm apart and RF frequency 1 MHz we find spin-echo length δ= 0.9 μm. We show numerically, how λ...

The emergence of climate change mitigation action by society: An agent-based scenario discovery study

Greeven, Sebastiaan (author), Kraan, O.D.E. (author), Chappin, E.J.L. (author), Kwakkel, J.H. (author)

Developing model-based narratives of society’s response to climate change is challenged by two factors. First, society’s response to possible future climate change is subject to many uncertainties. Second, we argue that society’s mitigation action emerge out of the actions and interactions of the many actors in society. Together, these two...

Effect and behaviour of different substrates in relation to the formation of aerobic granular sludge

Pronk, M. (author), Abbas, B. (author), Al-zuhairy, S.H.K. (author), Kraan, R. (author), Kleerebezem, R. (author), Van Loosdrecht, M.C.M. (author)

When aerobic granular sludge is applied for industrial wastewater treatment, different soluble substrates can be present. For stable granular sludge formation on volatile fatty acids (e.g. acetate), production of storage polymers under anaerobic feeding conditions has been shown to be important. This prevents direct aerobic growth on readily...

The Goos-Hänchen effect is a spatial shift along an interface resulting from an interference effect that occurs for total internal reflection. This phenomenon was suggested by Sir Isaac Newton, but it was not until 1947 that the effect was experimentally observed by Goos and Hänchen. We provide the first direct, absolute, experimental...
