Artificial intelligence (AI) and related technologies have become important components of the digital economy and affect core areas of our increasingly technologically networked lives. Specific AI ...technology can support diverse learners and how AI is used in particular in the context of Adult Education to provide a more inclusive and flexible learning environment. Artificial intelligence has been changing education for a long time now, and it is becoming more pervasive in our lives. The authors analyzed many advantages of using AI as an educational tool, such as increasing student engagement by improving grading accuracy by automatically scoring essays with machine learning algorithms. We present a case on how wireframes can be used in website design. Several existing tools have been examined, and their ability to generate interfaces from sketches has been explored. Creating wireframes, prototypes, design mock-ups, and layouts followed the web development process and is now a significant part of website development in engineering education. The paper aims to give the direct opportunity to observe examples of AI wireframes for engineering education.
This paper reflects on a case study of a user-centred concept development process for a Machine Learning (ML) based design tool, conducted at an industry partner. The resulting concept uses ML to ...match graphical user interface elements in sketches on paper to their digital counterparts to create consistent wireframes. A user study (N=20) with a working prototype shows that this concept is preferred by designers, compared to the previous manual procedure. Reflecting on our process and findings we discuss lessons learned for developing ML tools that respect practitioners’ needs and practices.
In this article, we explore the potential of wireframe design and evaluation for interactive and web-based mapping through a case study on water level visualization. Specifically, our research ...informed design and development of the National Oceanic & Atmospheric Administration's (NOAA) Lake Level Viewer (
http://coast.noaa.gov/llv/
), an interactive and web-based geovisualization application for the Great Lakes region of North America. As part of our overall user-centered design process, we created two sets of wireframes to evaluate two aspects of the user experience: high-fidelity wireframes to illustrate the proposed representation solution using real data and low-fidelity wireframes to provide a rough sketch of the proposed interaction solution. Eighteen target users completed cognitive walkthroughs of the wireframes, with the sessions audio-recorded for subsequent transcription and qualitative data analysis. The wireframe evaluations led to a series of revisions to the functional scope and visual design of the Lake Level Viewer. The process also generated recommendations for designing water level visualizations supporting adaptive management in response to climate change as well as for leveraging wireframes in support of large-scale mapping and GIS projects.
Context: Graphical User Interface (GUI) toolkits currently provide layout managers which lay out widgets in views according to certain constraints that characterise each type of layout manager. In ...some scenarios such as GUI migration and the automated generation of GUIs from wireframes, the layout of views is implicitly expressed through the use of coordinates. In these cases, it is desirable to represent the layout explicitly in terms of layout managers.
Objective: To represent a coordinate-based GUI in terms of a set of layout managers, in order to provide different alternative solutions for a given view and select the best alternative.
Method: The layout inference process consists of two phases. Firstly, the coordinate-based positioning system is changed to a relative positioning system based on directed graphs and Allen relations. Secondly, an exploratory algorithm based on pattern matching and graph rewriting is applied in order to obtain different layout solutions. The algorithm has been evaluated through a case study related to the automatic generation of fluid web interfaces from wireframes, involving 20 IT professionals.
Results: The case study showed that the layout obtained is faithful to the original views in 97% of cases, and maintains its proportions when resized in 84% of views. The majority of the participants were satisfied with the results and found the approach useful.
Conclusions: The layout manager representation obtained from the coordinate-based GUIs can be used to generate fluid layouts. The algorithm has two main features that overcome the limitations of the existing approaches: independence of specific layout managers and ability to generate several alternative solutions.
Self-assembling nucleic acid molecules have shown merit as versatile materials for organizing and constructing nanoscale structures with both 2D and 3D geometries. This chapter focuses on strategies ...in designing DNA gridiron nanostructures based on four-arm junction. This design strategies aims at controlling DNA self-assembly with a higher degree of spatial precision by depicting arbitrary 3D geometries with their wireframe outlines using DNA helices (for edges) and four-arm junctions (for vertices).
Traditional geostatistical modelling of orebodies and estimation of grade–tonnage curves do not account for the uncertainty of the orebody grades and tonnages. Geological interpretations of complex ...shapes are often over-constrained, and therefore do not properly identify the location of the ore. In these situations, tonnage is often under-estimated and grade is over-estimated, resulting in orebody models used for mine planning that lead to costly financial decisions. This paper presents an approach aiming to better assess the uncertainty in an orebody model. The approach is applied to Vale's West Orebody of the Coleman McCreedy Mine, a poly-metallic deposit containing nickel, copper, gold, platinum and palladium. To encapsulate the orebody's variability and uncertainty, the nickel–copper sulphide mineralized zone is simulated using the single normal equation simulation method. The realizations serve as the orebody models from which the grades of multiple elements are jointly simulated using Min/Max Autocorrelation Factors. The final result is a series of equiprobable representations of the mineralization that incorporates both grade and tonnage uncertainty. The case study indicates that had conventional orebody estimations been used, there would have been a 10% over-estimation of orebody volume, along with significant over-estimation of low-grade material and under-estimation of high-grade material.
