This paper describes a pattern language that is used to define a multimedia authoring environment capable of producing and utilising multimedia components. We believe that the effective construction of multimedia material should refrain from the common practice of building new documents and presentations entirely from scratch. Hence, the proposed pattern language emphasises the process of makin...

Smart environments established by the development of mobile technology have brought vast benefits to human being. However, authentication mechanisms on portable smart devices, particularly conventional biometric based approaches, still remain security and privacy concerns. These traditional systems are mostly based on pattern recognition and machine learning algorithms, wherein original biometr...

MOTIVATION A graphical representation of the exon-intron structure of various genes, such as that presented by the National Center for Biotechnology Information Map Viewer, suggests a digital waveform or pattern that varies either in amplitude or frequency. This observation suggests that different genes may have portions of their total exon-intron structure in common. The existence of common st...

Methods for detecting item score patterns that are unlikely (aberrant) given that a parametric item response theory (IRT) model gives an adequate description of the data or given the responses of the other persons in the group are discussed. The emphasis here is on the latter group of statistics. These statistics can be applied when a nonparametric model is used to fit the data or when the data...

A range of methodologies has been proposed to derive generalised forms of buildings at coarser scales. In this paper, we explore the use of simple pattern matching algorithms in order to select from a set of templates, a building outline that best characterises a more detailed form. This template matching process is used to simplify the form of rural buildings (farmsteads) in Danish mapping, an...

The need to handle increasingly complex application models and to efficiently interpret large volumes of data with adequate user support tools provides the main motivation for distributed virtual environments. Among the existing proposals, there is still a lack of support for the customization of the environment to specific application needs, and the possibility of its dynamic reconfiguration. ...

Consumption of business processes provided in form of Web sites have become a part of our daily life for attending our personal and business needs. In order to obtain the best solution for a particular task, users often combine several Web sites. However, currently the composition of Web sites, coordination of the execution of such Web sites compositions is done completely manually. In this pap...

Step and flash imprint lithography ~SFIL! is an alternative approach for printing sub-100 nm features that relies on chemical and mechanical techniques to transfer patterns. The imprint process requires no projection optics and is performed at room temperature with low imprint pressures to reduce thermal and mechanical template distortions. Because imprint lithographies are 13 pattern transfer ...

Directed self-assembly of block copolymers has been used for fabricating various nanoscale patterns, ranging from periodic lines to simple bends. However, assemblies of dense bends, junctions, and line segments in a single pattern have not been achieved by using sparse templates, because no systematic template-design methods for achieving such complex patterns existed. To direct a complex patte...

Computer assistance in synthesis design has existed for over 40 years, yet retrosynthesis planning software has struggled to achieve widespread adoption. One critical challenge in developing high-quality pathway suggestions is that proposed reaction steps often fail when attempted in the laboratory, despite initially seeming viable. The true measure of success for any synthesis program is wheth...
