Conventionally, stippling is an effective technique for representing surfaces in pen-and-ink. We present new efficient methods for stipple drawings by computer. In contrast to already existing techniques, arbitrary shapes can be used in place of dots. An extension of Lloyd’s Method enables us to position small objects on a plane in a visually pleasing form. This allows us to generate new illust...

We contend that current and future advances in Internet scale multimedia analytics, global inference, and linking can circumvent traditional security and privacy barriers. We therefore are in dire need of a new research field to address this issue and come up with new solutions. We present the privacy risks, attack vectors, details for a preliminary experiment on account linking, and describe m...

Innovation is among the key factors driving a country’s economic and social growth. But what are the factors that make a country innovative? How do they differ across different parts of the world and different stages of development? In this work done in collaboration with the World Economic Forum (WEF), we analyze the scores obtained through executive opinion surveys that constitute the WEF’s G...

This paper established strict image-object relationship model of ZY-3,and analyzed orbital data and attitude data statistically. It did camera geometric calibration using high-precision artificial target. Internal geometric correction of the original satellite images, eliminating the interior orientation parameters such as non-uniform transition, transition of the integration time and attitude ...

In this paper we introduce a new continuous dynamic controller for a class of nonlinear systems which includes mechanical system models with a bristle model for nonlinear friction eeects. We obtain suucient conditions for global stabilization using an estimate for bristle defec-tion and present experimental results illustrating the beneets of our dynamic controller in the regulation of a high s...

This paper explores how dimensions of new product, specifically, originality and usefulness, influence word-of-mouth (WOM). In four studies, using lab and field setups, we find that originality and usefulness have different effects on WOM. We show that consumers spread more WOM about original products, but the valence of what they say depends on product usefulness. Thus, originality enhances th...

Networked global learning communities build partnership programs between higher education institutions and high schools which allow students, teachers and professors to attend and work in college preparation programs located in countries outside of their native lands. These educational programs help to promote development of transnational policies and procedure reforms to provide access to univ...

The paper presents a size-adapted assembly system for the automated precision assembly of active microsystems. The part sizes of the microsystems can reach centimeter range, but they must be assembled with an assembly accuracy of about a few micrometers. The results of a sensor guided assembly process using a 3D vision sensor are shown. This process reaches a positioning uncertainty of 1.2 μm a...
