This paper presents a project involving a percussionist playing on a virtual percussion. Both artistic and technical aspects of the project are developed. Especially, a method for strike recognition using the Flock of Birds is presented, as well as its use for artistic purpose.

This paper presents a parallel spatial clustering algorithm based on the use of new Swarm Intelligence (SI) techniques. SI is an emerging new area of research into Artificial Life, where a problem can be solved using a set of biologically inspired (unintelligent) agents exhibiting a collective intelligent behaviour. The algorithm, called SPARROW, combines a smart exploratory strategy based on a...

BACKGROUND Resistance against benzimidazoles (BZ) has recently been detected in Norwegian sheep flocks through a large scale prevalence survey based on the faecal egg count reduction test (FECRT). The use of this test in combination with bulk larval culture only gives an indication of which gastrointestinal nematodes genera that are involved and these results have to be confirmed by a controlle...

The size and species composition of bird flocks in a mixed-conifer forest of the western Sierra Nevada was nearly identical over three winters. Golden-crowned Kinglets (Regulus satrapa), Chestnut-backed Chickadees (Parus rufescens), and Red-breasted Nuthatches (Sitta canadensis) had the highest number of individuals/flock. Kindets and nuthatches were the most frequent flockmembers, although the...

Many solutions have been proposed where energy awareness is essential consideration for stable routing. In this proposed work, hybrid of reactive flock-cluster and proactive-cluster routing algorithm based on the residual energy, fitness function and Euclidean distance of nodes in heterogeneous wireless sensor network. The algorithm consists of both reactive and proactive setup phase. In a reac...

We present a quantitative continuum theory of " flocking " : the collective coherent motion of large numbers of self-propelled organisms. In agreement with everyday experience, our model predicts the existence of an " ordered phase " of flocks, in which all members of even an arbitrarily large flock move together with the same mean velocity v = 0. This coherent motion of the flock is an example...

The two classes of semifield spreads of Cossidente et al. arising from their Hermitian ovoids are completely determined as a set of Kantor-Knuth flock semifield spreads and a set of Hughes-Kleinfeld semifield spreads.

We sampled 1,091 Icelandic broiler flocks at slaughter from May 2001 to December 2003 to determine the prevalence of, and investigate risk factors for the presence of, Campylobacter spp. at the flock level. Approximately 15% of the flocks were positive for Campylobacter spp.; most (95%) of the infected flocks being raised during the months of April-September. Based on the data from the latter m...
