Research shows that people handle the complexity of environments by cognitively simplifying them using spatial schemas and heuristics. Such simplification strategies can be seen in route planning situations, such as the Travelling Salesperson Problem (TSP) and tour planning. The present study extends this work by examining a situation where memory demands must be considered during route plannin...

Rendering massive 3D models in real-time has long been recognized as a very challenging problem because of the limited computational power and memory space available in a workstation. Most existing rendering techniques, especially level of detail (LOD) processing, have suffered from their sequential execution natures, and does not scale well with the size of the models. We present a GPUbased pr...

Numerical simulations of tubulent flows produce both vector and tensor fields that exhibit complex structural behavior. The topological study of these datasets dramatically reduces the amount of information required for analysis. However, the presence of many features of small scale creates a cluttered depiction that confuses interpretation. In this paper, we extend previous work dealing with v...

We give a new simplification method, called E-cycle Simplification, for Basic Completion inference systems. We prove the completeness of Basic Completion with E-cycle Simplification. We prove that E-cycle Simplification is strictly stronger than the only previously known complete simplification method for Basic Completion, Basic Simplification, in the sense that every derivation involving Basic...

This work addresses an autonomous underwater vehicle (AUV) for applying nonlinear control which is capable of disturbance rejection via intelligent estimation of uncertainties. Adaptive radial basis function neural network (RBF NN) controller is proposed to approximate unknown nonlinear dynamics. The problem of designing an adaptive RBF NN controller was augmented with sliding mode robust term ...

A very fast mesh simplification algorithm based on halfedge collapse is proposed in this work with a focus on progressive graphic transmission applications. We generalize the Quadric Error Metric (QEM) method to accommodate new topological operations. A flatness criterion is combined with the defined metric to preserve the visual quality of simplified meshes. We further adopt the vertex-based p...

We present a language technology service for web editors’ work on making texts easier to understand, including tools for text complexity analysis, text simplification and text summarization. We also present a text analysis service focusing on measures of text complexity.

We describe a simplification of Donaldson’s arguments for the construction of symplectic hypersurfaces [4] or Lefschetz pencils [5] that makes it possible to avoid any reference to Yomdin’s work on the complexity of real algebraic sets.

The article at hand aggregates the work of our group in automatic processing simplified German. We present four parallel (standard/simplified German) corpora compiled and curated by group. report on creation a gold standard sentence alignments from sources for evaluating alignment methods this standard. show that one performs best majority data sources. used two as basis first sentence-based ne...

Level of detail was one of the fundamental solutions of simplification 3D scene. But some issues with this solution are present. For example the topology of the mesh is not kept. In this paper we introduce the Reeb graph in level of detail. Reeb graph is a topological extractor for graph. We extract the most important point of a mesh and use them as LOD. These points are representing by a skele...
