Dancer [3] found a necessary and sufficient condition for the existence of periodic solutions to the equation ẍ+ g1(ẋ) + g0(x) = f(t) . His condition is based on a functional that depends on the solution to the above equation with g0 = 0. However, that solution is not always explicitly known which makes the condition unverifiable in practical situations. As an alternative, we find computable bo...

The plant considered in this paper is an unwinding winding system with pendulum dancer mechanism for elastic webs. First, a non linear mathematical model of the web process line is presented. A state space model is deduced which helps in the synthesis of the H∞ controllers around the set points given by the reference signals. Industrials systems typically use decentralized PI controllers. In th...

The construction of new hyperkähler manifolds by taking the infinite monopole mass limit of certain BPS monopole moduli spaces is considered. The one-parameter family of hyperkähler manifolds due to Dancer is shown to be an example of such manifolds. A new family of fixed monopole spaces is constructed. They are the moduli spaces of four SU4 monopoles, in the infinite mass limit of two of the m...

<p style='text-indent:20px;'>We discuss some recent results (mostly from the last decade) on stable and finite Morse index solutions of semilinear elliptic equations, where Norman Dancer has made many important contributions. Some open questions in this direction are also discussed.</p>

This study investigated the longitudinal process of practice by an expert dancer in breakdance. We examined the ability of the concept of “deliberate practice” (Ericsson, Krampe, & Tesch-Römer, 1993) to provide a full account of the practice process of an expert dancer. We conducted a fieldwork study to observe the practice of expert dancers under natural conditions, and analyzed data gathered ...

What we see is a function not only of incoming stimulation, but of unconscious inferences in visual processing. Among the most powerful demonstrations of this are bistable events, but what causes the percepts of such events to switch? Beyond voluntary effort and stochastic processing, we explore the ways in which ongoing dynamic percepts may switch as a function of the content of brief, unconsc...

This is intended to introduce the system, which combines BodySuit, especially Powered Suit, and Second Life, as well as its possibilities and its uses in a musical performance application. The system which we propose contains both a gesture controller and robots at the same time. In this system, the Data Suit, BodySuit controls the avatar in Second Life and Second Life controls the exoskeleton,...

BACKGROUND Dance is essentially an artistic discipline, with the dancer being exposed, as in any other occupation, to occupational risk factors. This document aims at identifying the characteristics about Professional Dance and its impact on the dancer's health. METHODS Bibliographical review of all the material indexed at: Medline, Embase, Cochrane Library, Lilacs, Cinhal and IME. Using the ...

Recent research revealed that emotional content can be successfully decoded from human dance movement. Most previous studies made use of videos of actors or dancers portraying emotions through choreography. The current study applies emotion induction techniques and free movement in order to examine the recognition of emotional content from dance. Observers (N = 30) watched a set of silent video...

Though associative recognition memory is thought to rely primarily on recollection, recent research indicates that familiarity might also make a substantial contribution when to-be-learned items are integrated into a coherent structure by means of an existing semantic relation. It remains unclear how different types of semantic relations, such as categorical (e.g., dancer-singer) and thematic (...
