This paper presents a method that automatically detects the location of the title block in scanned technical drawings. Numerous applications could benefit from such a tool. For example, it is useful to locate and zoom on the drawing title block, which can help in indexing technical drawings. As the title block is normally on the right-bottom corner of the drawing, it can also permit turning the...

Human-like robots combine the optimized biological morphology and functionality of the real human with the mechanical constraints and limitations in the creation as well as possible. This will be a trade-off at all times. The best biological solution of a detail is often simple in the function but too complex for the technical analogue. The technical materials are often missing what make a one-...

This paper presents a new approach to classify, index and retrieve technical drawings by content. Our work uses spatial relationships, visual elements and high-dimensional indexing mechanisms to retrieve complex drawings from CAD databases. This contrasts with conventional approaches which use mostly textual metadata for the same purpose. Creative designers and draftspeople often re–use data fr...

Technological and scientific images, and other images with epistemic uses, have varied appearances and functions. They seem to be analog or symbolic representations available to researchers for a variety of epistemic purposes such as summarizing data, or presenting, discussing and verifying hypothetic propositions about the world. This article studies the perception and understanding of scienti...

Extremist organizations are heavily utilizing Internet technologies to increase their abilities to influence the world. Studying those global extremist organizations’ Internet presence would allow us to better understand extremist organizations’ technical sophistication and their propaganda plans. In this work, we explore an integrated approach for collecting and analyzing extremist Internet pr...

We investigate predictability of asset returns by developing an approach that combines technical analysis and conventional time series forecasts. While exploiting predictable components as functions of past prices or returns, technical trading rules and time series forecasts capture different aspects of market predictability: the former tends to identify periods to be in the market when returns...

A new curriculum, Scientific Visualization, is being taught by high school technical graphics and science teachers for the first time in the Fall of 1997. This curriculum reflects a broadening application of computer graphics techniques in the workplace and represents a rich area for technical graphics teachers at all levels of education to be involved in. The goal of the two-course sequence at...

An (encoded) decision problem over Σ is a pair (E,F ) where E=words that encode instances of the problem, F=words to be accepted. We use strings in a technical sense, borrowed from Computability. With any NP problem (E,F ) we associate a set of strings |LogE(F )| called the reduced logogram of F relative to E, which conveys structural information on E, F , and how F is embedded in E. We define ...
