The effects of methanol fuel on combustion in premixed dual fuel engine

Lee, B. (author)

The environmental pollution and depleting fossil fuels have been considered as a critical issue all over the world. Many efforts have been devoted to investigating alternative fuels to tackle these problems. Alcohol fuels are potential candidates to alternative energy as it can mitigate pollutant emission. In addition, alcohol fuels can be...

Feasibility of increasing the pedestal height on the J-class vessel by 10 meters

Lee, M. (author)

In order for Jumbo to stay competitive in the offshore market, it's heavy lift vessels should be able to take on a wide range of lifting purposes. This can range from installation of transition pieces for wind turbines to installing modules of fpso's and platforms. One of the demands from the offshore market requires large lifting heights. It is...

Repeated crack healing in MAX-phase ceramics revealed by 4D in situ synchrotron X-ray tomographic microscopy

Sloof, W.G. (author), Pei, R. (author), McDonald, S.A. (author), Fife, J.L. (author), Shen, L. (author), Boatemaa, L. (author), Farle, A.S. (author), Yan, K. (author), Zhang, X. (author), Van der Zwaag, S. (author), Lee, P.D. (author), Withers, P.J. (author)

MAX phase materials are emerging as attractive engineering materials in applications where the material is exposed to severe thermal and mechanical conditions in an oxidative environment. The Ti2AlC MAX phase possesses attractive thermomechanical properties even beyond a temperature of 1000 K. An attractive feature of this material is its...

Rendering 6-DOF Object-to-Object Interaction with 3-DOF Haptic Interfaces

Lee, T.C. (author)

Three degree-of-freedom (3-DOF) tool-based haptic interfaces are widely used in virtual environment to train operators, and for virtual prototyping and design. In some special cases with higher requirement on haptic fidelity, the tool needs to be modeled as an object with real volume rather than a single point. However, such object -to-object...

A hybrid semiconductor-glass waveguide laser

Fan, Y. (author), Oldenbeuving, R.M. (author), Klein, E.J. (author), Lee, C.J. (author), Song, H. (author), Khan, M.R.H. (author), Offerhaus, H.L. (author), Van der Slot, P.J.M. (author), Boller, K.J. (author)

We report on a novel type of laser in which a semiconductor optical amplifier (SOA) receives frequency-selective feedback from a glass-waveguide circuit. The laser we present here is based on InP for operation in the 1.55 µm wavelength range. The Si3N4/SiO2 glass waveguide circuit comprises two sequential high-Q ring resonators. Adiabatic...

A novel and simple approach to optical wavelength measurement is presented in this paper. The working principle is demonstrated using a tunable waveguide micro ring resonator and single photodiode. The initial calibration is done with a set of known wavelengths and resonator tunings. The combined spectral sensitivity function of the resonator...

Receding Horizon H (infinity) Control for Input-Delayed Systems

Yoo, H.W. (author), Han, S. (author), Lee, Y.S. (author)

We propose the receding horizon H (infinity) control (RHHC) for input-delayed systems. A new cost function for a finite horizon dynamic game problem is first introduced, which includes two terminal weighting terms parameterized by a positive definite matrix, called a terminal weighing matrix. Secondly, the RHHC is obtained from the solution to...

Indirect measurement of pinch and pull forces at the shaft of laparoscopic graspers

Van den Dobbelsteen, J.J. (author), Lee, R.A. (author), Van Noorden, M. (author), Dankelman, J. (author)

The grasping instruments used in minimally invasive surgery reduce the ability of the surgeon to feel the forces applied on the tissue, thereby complicating the handling of the tissue and increasing the risk of tissue damage. Force sensors implemented in the forceps of the instruments enable accurate measurements of applied forces, but also...
