The model-based approach to user interface design relies on developing separate models that are capturing various aspects about users, tasks, application domain, presentation and dialog representations. This paper presents a task modeling approach for user interface design and aims at exploring the mappings between task, domain and presentation models. The basic idea of our approach is to ident...

In immiscible two-phase flows, jumps or kinks are present in the velocity and pressure fields across the interfaces of the two fluids. The extended finite element method (XFEM) is able to reproduce such discontinuities within elements. Robust and accurate interface capturing schemes with no restrictions on the interface topology are thereby enabled. This paper investigates different enrichment ...

The aim of this presentation is to highlight the role that Particle-based simulations and Radial Basis Functions (RBFs) have played in the development of a computationally efficient, level-set, Finite Element method for the simulation of Newtonian and non-Newtonian interface flows [1]. First, we introduce the mathematical formulation and the interface-capturing technique used in the simulation ...

Security is generally a state or feeling of being saved and protected, an assurance that something of value will not be taken. This paper employs two of the emerging artificial intelligence technologies: Facial Recognition and Artificial Neural Networks for developing a secure keyless door where authentication of authorized faces are the only guarantee for entry. This mechanically built door, w...

We present the animation loop station, a near real-time animation production system. It brings the concept of loop stations or loopers commonly used for live music performances to the animation domain. Our system allows a single animator to build an animation layer by layer by capturing his own movement and building up complex motion through several passes or takes. In order not to interfere wi...

We propose and study parallel numerical algorithms for simulation of flows with elastic membranes, such as red blood cells. The challenges of modeling such flows include accurately resolving the interface motion and enforcing the appropriate interface mechanics. We propose a phase field Eulerian method for implicitly capturing the location of the dynamic interface between two fluids. In additio...

Modeling mechanical joints in an accurate and computationally efficient manner is of great importance in the analysis of structural systems, which can be composed of a large number of connected components. This work presents an interface model that can be decomposed into a series-series Iwan model together with an elastic chain, subject to interfacial shear loads. A reduced-order formulation of...

The model-based approach to user interface design relies on developing separate models capturing various aspects about users, tasks, application domain, presentation and dialog structures. This paper presents a task modeling approach for user interface design and aims at exploring mappings between task, domain and presentation models. The basic idea of our approach is to identify typical config...

Designing usable systems is difficult and designers need effective tools that are usable themselves. Effective design tools should be based on proven knowledge of design. Capturing knowledge about the successful design of usable systems is important for both novice and experienced designers and traditionally, this knowledge has largely been described in guidelines. However, guidelines have show...

In this paper, a new fifth-order weighted essentially non-oscillatory scheme is developed. Necessary and sufficient conditions on the weights for fifth-order convergence are derived; one more condition than previously published is found. A detailed analysis reveals that the version of this scheme implemented by Jiang and Shu [G.-S. Jiang, C.-W. Shu, Efficient implementation of weighted ENO sche...
