Cameras are often mounted on platforms that can move like rovers, booms, gantries and aircraft. People operate such platforms to capture desired views of scene or target. To avoid collisions with the environment and occlusions, such platforms often possess redundant degrees-of-freedom. As a result, manipulating such platforms demands much skill. Visual-servoing some degreesof-freedom may reduce...

This article pursues two tasks. The first is to clarify the value and productivity of Williams’s Keywords: a vocabulary culture society (first edition 1976, second expanded 1983a) for project Cultural Studies. clarification helped, I argue, by reading it alongside Vološinov’s Marxism philosophy language (published in Russian 1929, translated into English 1973). related task speculative developm...

We discuss quantum dynamics in multi-dimensional non-linear systems. It is well-known that wave function is localized in a single kicked rotor. However, coupling with other degrees of freedom breaks the localization. In order to clarify the difference in the quantum dynamics, we use rigid quantum trajectories, which is accompanied with the de BroglieBohm interpretation of the quantum mechanics....

We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

In this study, we focus on the intelligent behavior of an octopus and describe the development of a flexible manipulator. By using the developed manipulator, we show that grasping behaviors similar to those of an octopus can be realized by the dynamics of the body without computation in its brain. Keywords-flexible manipulator; octopus; many degrees of freedom; grasping.

Diversity is often thought to create conflict and harm economic institutions. We hypothesize, however, that the impact of diversity is conditional on political institutions, and may be negative in some settings but positive in others, due to differences in the nature of rent seeking in different regimes. To test this hypothesis, we estimate the impact of diversity on economic freedom, condition...
