The advent of hypertext has opened up new possibilities in computer-based training. The design of courseware without any predetermined structure could make the designer’s task easier, and allow greater flexibility for the trainee to structure the learning environment to suit their own learning style. This investigation was concerned with the exploration of performance differences in structured ...

Although the quantity of structured information on the Web and within organizations is increasing, the majority of information remains available only in unstructured form. While different in form, both unstructured and structured information sources provide information about entities in the world and their properties and relations; still, frameworks for their seamless integration have not been ...

Open source information on the internet can contribute significantly to intelligence assessments. Unfortunately, this information is mostly unstructured text, and varies widely in accuracy, focus, and level of impartiality. Though such unstructured information may be organized for convenient review in information portals, it is difficult to visualize, link, consolidate, summarize, compare, fuse...

One of the most difficult problems in reverse engineering is the processing of unstructured data. NURBS (Non-uniform Rational B-splines) surfaces are a popular tool for surface modeling. However, they cannot be directly created from unstructured data, as they are defined on a four-sided domain with explicit parametric directions. Therefore, in reverse engineering, it is necessary to process uns...

In this paper a computational method is presented for predicting the unsteady hydrodynamic forces acting on partial immersed propeller (SPP). In order to simulate the unsteady viscous flow around a SPP, a Reynolds-Averaged Navier–Stokes (RANS) solver is used. The time-accurate calculations are made by applying the sliding mesh method. Structured and unstructured mesh techniques are used. ...

The Radial Basis Function (RBF) technique is an interpolation method that produces high-quality unstructured adaptive meshes. However, the RBF-based boundary problem necessitates solving a large dense linear system with cubic arithmetic complexity computationally expensive and prohibitive in terms of memory footprint. In this article, we accelerate computations 3D mesh deformation based on RBF ...

Developing computationally efficient semantic segmentation models that are suitable for resource-constrained mobile devices is an open challenge in computer vision research. To address this challenge, we propose a novel real-time scene model called Multi-encoder Context Aggregation Network (MCANet), which offers the best combination of low complexity and state-of-the-art (SOTA) performance on b...
