The male effect refers to the effect of the introduction of the male on the oestrus cycle of the seasonally anoestrus female. This effect is a neuro-hormonal response that is utilised by flock managers to improve the ovulation rate in females and shorten the breeding season. The introduction of males to the female flock will elicit this response but the use of vasectomised males is a common pra...

In 1965 Knuth [4] showed that from a given finite semifield one can construct further semifields manipulating the corresponding cubical array, and obtain in total six semifields from the given one. In the case of a rank two commutative semifield (the semifields corresponding to a semifield flock) these semifields have been investigated in [1], providing a geometric connection between these six ...

Shepherding in flocking models has been done since Craig Reynolds invented flocking using local interaction rules [4]. Since then most shepherding flocking models came with two agents: a herd-able agent and a shepherd. These agent were made for each other in the sense that they exert nice and realistic behavior when used together. In this thesis a method will be devised that is able to shepherd...

As supervisor of the banks, the Reserve Bank has been likened to the shepherd tending his flock. Keeping the flock intact over the past decade, after the regulatory fences came down, has had its moments. A couple have wandered off, and a couple have lost more than their tails. But no carcasses litter the landscape. Indeed, the flock today is looking stronger and healthier than it has for some t...

Epsilon is an extensible platform of integrated and task-specific languages for model management. With solutions to the 2011 TTC Hello World case, this paper demonstrates some of the key features of the Epsilon Object Language (an extension and reworking of OCL), which is at the core of Epsilon. In addition, the paper introduces several of the task-specific languages provided by Epsilon includi...

aedi-Visna is a viral disease of sheep caused by a lentivirus. It is characterized by progressive interstitial pneumonia or meningoencephalitis. Sometimes arthritis, ill-thrift and indurative mastitis are observed. The disease most often progresses slowly, but irreversibly. The disease occurs in all major sheep producing countries with the exception of Australia, New Zealand, and Finland. The i...

The paper presents contributions to the design of the Flock of Trackers (FoT). The FoT estimates the pose of the tracked object by robustly combining displacement estimates from a subset of local trackers that cover the object and has been. The enhancements of the Flock of Trackers are: (i) new reliability predictors for the local trackers the Neighbourhood consistency predictor and the Markov ...

Five clinically normal chickens from three farms (farm A, farm B, and farm C), for a total of 15 clinically normal chickens, were examined bacteriologically. In a similar manner, five dead chickens with lesions of peritonitis from each of the same three commercial egg-laying operations were selected for bacterial culturing. Escherichia coli were isolated from the cloaca in 14 of 15 healthy chic...
