Using standard samples is a simple yet very effective method to control data quality. In the field of Quaternary science, it is a commonly applied approach for isotope and geochemical analyses, greatly increasing the general level of confidence in these analytical methods. Microfossil analysis, by contrast, does not normally have any such system to secure data precision and accuracy objectively...

This paper provides an effective method to create an abstract simplicial complex homotopy equivalent to a given set S described by non-linear inequalities (polynomial or not). To our knowledge, no other numerical algorithm is able to deal with this type of problem. The proposed approach divides S into subsets that have been proven to be contractible using interval arithmetic. The method is clos...

In this paper, we propose an efficient and effective method to find arbitrarily oriented subspace clusters by mapping the data space to a parameter space defining the set of possible arbitrarily oriented subspaces. The objective of a clustering algorithm based on this principle is to find those among all the possible subspaces, that accommodate many database objects. In contrast to existing app...

The lattice E of c.e. sets is a popular object of study in Computability Theory [So87]. A principal fact about this lattice is the undecidability of its first-order theory Th(E). Moreover, Th(E) is known [HN98] to be m-equivalent to the first-order arithmetic Th(N) where N := (ω; +,×). The lattice E may be considered as the lattice of effectively open subsets of the discrete topological space ω...

Author Co-citation Analysis (ACA) has long been used as an effective method for identifying the intellectual structure of a research domain, but it relies on simple co-citation counting, which does not take the citation content into consideration. The present study proposes a new method for measuring the similarity between co-cited authors by considering author's citation content. We collected ...

This paper describes a new and cost effective method of analyzing hard rock discontinuities from oriented core bore hole data. This algorithm uses multivariate cluster analysis to group discontinuities (joints) into sets based on orientation and spatial position (spacing) along the bore hole, and to display the data in a three dimensional stereonet. Although drift or surface exposure mapping da...

As the size and cost of sensors decrease, sensor networks are increasingly becoming an attractive method to collect information in a given area. However, one single sensor is not capable of providing all the required information, either because of their design or because of observational constraints. One possible solution to get all the required information about a particular scene or subject i...

Remote rendering and visualization for large geometrical models or complex scenes calls for efficient transmission. One effective method for the transmission is to stream the model data based on region-of-interest (ROO strategies and partial updating of consecutive 6ames. In this paper, we propose such an interactive streaming transmission scheme for point-based models. The technique of view-de...

This paper describes a content-based analysis of Web-based travellers’ social media Websites. The proposed methodology is based on three levels of computer-mediated analysis, namely the lexical analysis, statistical analysis and semantic analysis. It is found that the use of systematic analysis of naturally occurring discussions in social media sites can lead to much stronger information about ...

How do we balance risks? This paper assesses hypotheses derived from instrumental rationality and risk society theories about the reasoning strategies that people will use to develop views supportive or oppositional to the use of herbicides to manage cheatgrass (Bromus tectorum), an invasive weed. Cheatgrass is well-known in the population of the American West to increase wildfire risks substan...
