Flocking Regimes in a Simple Lattice Model [PDF]

, 2005
We study a one-dimensional lattice flocking model incorporating all three of the flocking criteria proposed by Reynolds [Computer Graphics vol.21 4 (1987)]: alignment, centring and separation. The model generalises that introduced by O. J. O' Loan and M.

Effects of oxygen concentration during incubation and broiler breeder age on embryonic heat production, chicken development, and 7-day performance

Animal, 2021
Older breeder flocks produce eggs with a relatively larger yolk and thereby a higher nutrient availability than young breeder flocks. To optimise nutrient utilisation and embryonic development throughout incubation and posthatch period, embryos ...

Linear response to leadership, effective temperature and decision making in flocks [PDF]

, 2016
Large collections of autonomously moving agents, such as animals or micro-organisms, are able to 'flock' coherently in space even in the absence of a central control mechanism.

Grouping strategies and lead factors for ration formulation in milking ewes of the Chios breed [PDF]

, 2008
The aim of this study was to develop an efficient strategy for ration formulation for milking ewes of the Chios breed in Greece. The strategy involved two and three groupings according to production level and challenge feeding using lead factors.

Profitability of dairy and goat production system: A multivariate typology of farm households

Indian Journal of Animal Sciences, 2020
Using households' data from four different agro-climatic zones of Maharashtra, a typology was developed with an aim to identify factors influencing the profitability of dairy and goat production system. Multivariate statistical techniques, i.e.

Living on the edge: forest edge effects on microclimate and terrestrial mammal activity in disturbed lowland forest in Sumatra, Indonesia

Oryx
Species–environment relationships are often studied at large spatial scales, but effective conservation requires an understanding of local-scale environmental drivers and pressures.

Elation generalised quadrangles of order (s,p), where p is prime

, 2007
We show that an elation generalised quadrangle which has p+1 lines on each point, for some prime p, is classical or arises from a flock of a quadratic cone (i.e., is a flock quadrangle).Comment: 14 ...

Emergent velocity agreement in robot networks [PDF]

, 2011
In this paper we propose and prove correct a new self-stabilizing velocity agreement (flocking) algorithm for oblivious and asynchronous robot networks. Our algorithm allows a flock of uniform robots to follow a flock head emergent during the computation
