We consider the problem of morphing between two planar drawings of the same triangulated graph, maintaining straight-line planarity. A paper in SODA 2013 gave a morph that consists of O(n) steps where each step is a linear morph that moves each of the n vertices in a straight line at uniform speed [1]. However, their method imitates edge contractions so the grid size of the intermediate drawing...

Drawing on the work of Scheler, Heidegger, Merleau-Ponty, Husserl and Sartre, this article presents an overview of some of the diverse approaches to intersubjectivity that can be found in the phenomenological tradition. Starting with a brief description of Scheler’s criticism of the argument from analogy, the article continues by showing that the phenomenological analyses of intersubjectivity i...

The availability of a variety of sophisticated data acquisition instruments has resulted in large repositories of imagery data in different applications like non-destructive testing, technical drawing, medicine, museums and so one. Effective extraction of visual features and contents is needed to provide meaningful index of and access to visual data. In this paper, we propose an image database ...

• Throughout the developing world women die during pregnancy and in childbirth from hemorrhage (20-35%), unsafe abortion (10-15%), eclampsia or hypertension (10-15%), infection (10-15%), and obstructed labor (10-15%) (see Technical Note 1). Those that survive spend their reproductive years suffering from chronic anemia and the debilitating consequences of complications associated with reproduct...

The field of ethnomathematics is the study of mathematics in the works of art of various cultures [2, 3, 9, 13]. The concepts in this paper are inspired by the visual art of sand drawings that has developed independently in different forms in diverse cultures. Generally speaking, the artist draws a set of dots on some flat surface (usually in the sand or in powder on the floor) and then draws o...

The choice of a commercial Optical Character Recognition (OCR) engine is important for the process of automatically indexing technical drawings from their title blocks. We would like to benchmark commercial OCR engines with respect to their inclusion in the global digitalisation chain from scanning to understanding the text information contained in a technical drawing document. The crucial (cos...

Drawing on the familiar material from NASA’s lunar explorations and a serendipitous encounter with a memento from the Apollo 11 mission, I am working on an animated film featuring a single, looping orbit around the moon. Rendered from a computer model where planetary positions and orbits are plotted to correspond as far as possible to actuality, the lunar surface itself is based on data collect...

This paper outlines the conversion of a psychometric test to a web-based study. The test measures understanding of three-dimensional (3D) concepts as it applies to technical drawing. We describe the instrument in terms of its subtests and examine implementation and data collection issues. Comments are provided about technical, experimental design, participation and recruitment matters. We repor...

This paper proposes a new research perspective on resistance to information systems (IS) change. Drawing upon a power lens and complementing it with the organizational literature on resistance, we develop an integrative framework that conceptualizes resistance at three levels: 1) the non-compliance behaviors, 2) the meanings and norms that resisters contest and enact, and 3) the technical artif...

This paper proposes a holistic approach to enhance human knowledge in distributed and strictly linked contexts. Current semantic web technologies focus their attention only on the machine side of the interaction process. Our approach considers both the human and the machine working together to accomplish a task, stressing the importance of adapting data, tools and interactions to the different ...
