Dynamic mechanical analysis of (Ca,Sr)AlSiN3: Eu2+ phosphor/silicone composites aged under the temperature–humidity–sulfur coupled condition

As a core packaging material of light color conversion, phosphor/silicone composite plays an indispensable role in light emitting diode (LED) packaging. At present, commercial LED packages mainly use blue LED chips to stimulate Yttrium Aluminum Garnet (YAG) yellow phosphor to reach a white color. However, (Ca,Sr)AlSiN 3 :Eu 2+ (CSASN) red...

Model Predictive Control for Helicopter Flight Control: Evaluating Linear and Nonlinear Model Predictive Control for Reducing Cross-coupling Effects in Helicopter Flight

Model predictive control is an optimal, model-based control method that has the powerful capability of directly including input and output constraints. Next to this, it is known that helicopters are hard to fly with its complex, unstable and highly coupled dynamics. With the introduction of the concept of handling qualities, guidelines for...

Analysis of Coupling Effect in Human-Commanded Stiffness During Bilateral Tele-Impedance

Tele-impedance augments classic teleoperation by enabling the human operator to actively command remote robot stiffness in real-time, which is an essential ability to successfully interact with the unstructured and unpredictable environment. However, the literature is missing a study on benefits and drawbacks of different types of stiffness...

The coupling effect in bilateral tele-impedance: Beneficial or detrimental for unstructured environment interaction?

Tele-impedance augments classical teleoperation by enabling the human operator to actively command remote robot stiffness. Hereby, an essential strategy used by humans to successfully interact with the unstructured environment complements remote robot-environment interaction. However, literature lacks awareness of benefits and disbenefits of...

Analytical Modelling of Fluid-Structure Interaction: On Developing Equations to Understanding Rizos' Experiment (2016)

The activities of humans in the marine environment are on a steady rise; this trend follows the exposure of offshore structures and vessels to harsh environmental conditions. On the other hand, there is continuous demand for lighter, faster and more efficient vessels. Technological advancement in composite materials and better design methods...

Surface temperature excess in heterogeneous catalysis

In this dissertation we study the surface temperature excess in heterogeneous catalysis. For heterogeneous reactions, such as gas-solid catalytic reactions, the reactions take place at the interfaces between the two phases: the gas and the solid catalyst. Large amount of reaction heats are released at the interface for strong exothermic...
