In [3] have been constructed very high order residual distribution schemes for scalar problems. They were using triangle unstructured meshes. However, the construction was quite involved and was not very flexible. Here, following [1], we develop a systematic way of constructing very high order non oscillatory schemes for such meshes. Applications to scalar and systems problems are given.

Substructuring in the finite element method is a technique that reduces computational cost and memory usage for analysis of complex structures. The efficiency of this technique depends on the number of substructures in different problems. Some subdivisions increase computational cost, but require little memory usage and vice versa. In the present study, the cost functions of computations and me...

The performance of a contracting company is closely linked with the quality of the decisions at the strategic level. However, the increasing complexity of organizations’ internal and external environments and the unstructured nature of decisions at the strategic level make the decision making a very complicated task. The number of influential variables is so large and their effects are so varie...

Features of borderline personality disorder (BPD) are associated with the presence and severity of interpersonal problems. At the same time, individuals with BPD are heterogeneous with regard to the types of interpersonal problems they display. BPD is also associated with temporal instability in various domains (e.g., affective lability), and this characteristic raises questions about whether B...

There is an increasing demand for mesh-based PDE simulations to provide reliable solutions for complex problems. A key step in ensuring simulation reliability is the application of unstructured adaptive meshing driven by error estimation procedures. Typically, interfacing of unstructured adaptive procedures with existing analysis components is done through files. File I/O is currently the criti...

A mobile robot navigating in an unstructured environment faces many difficult problems for which vision may potentially offer useful solutions. The XT-1 (eXpectation based Template matching) architecture was developed in an attempt to address many of these problems with similar constructions. The current system handles such diverse problems as landmark and place recognition, the generation of o...

this paper presents a robust fractional order controller for flexible-joint electrically driven robots under imperfect transformation of control space. the proposed approach is free from manipulator dynamics, thus free from problems associated with torque control strategy in the design and implementation. as a result, the proposed controller is simple, fast response and superior to the torque c...

The issue of mesh quality for unstructured triangular and tetrahedral meshes is considered. The theoretical background to finite element methods is used to understand the basis of present-day geometrical mesh quality indicators. Simple tetrahedral mesh quality measures using both geometrical and solution information are described. Some of the issues in mesh quality for unstructured tetrahedral ...

A retrospective method for the performance comparison of queries based on different IR models is introduced. The method is based on the interactive optimisation of queries by a group of test searchers using a query performance analyser. The case experiment focused on comparing the maximum effectiveness of Boolean exact-match queries, and structured and unstructured best-match queries. The exper...
