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...

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...

In a flock of artificially reared turkeys originally consisting of 85 birds and reduced during the summer and fall by deaths and withdrawals for experimental purposes to 42 birds, five cases of blackhead occurred. These appeared during the months of July, September, and October. In four, Heterakis was searched for and found. In 38 birds from this flock killed for food during November and Decemb...

BACKGROUND Most previous analyses of scrapie outbreaks have focused on flocks run by research institutes, which may not reflect the field situation. Within this study, we attempt to rectify this deficit by describing the epidemiological characteristics of 30 sheep flocks naturally-infected with classical scrapie, and by exploring possible underlying causes of variation in the characteristics be...

Group foragers may assess patch quality more efficiently by paying attention to the sampling behavior of group members foraging in the same patch (i.e., using ‘‘public information’’). To determine whether red crossbills (Loxia curvirostra) use public information to aid their patch departure decisions, we conducted experiments that compared the sampling behavior of crossbills foraging on a two-p...

Many regulatory and diagnostic programs for the detection of Salmonella enterica serotype Enteritidis infection in commercial poultry flocks have relied on rapid Pullorum agglutination tests to screen birds because of the shared antigens of S. enterica Enteritidis and S. enterica Pullorum and Gallinarum; however, the use of the enzyme-linked immunosorbent assay (ELISA) format affords better ana...

Feed intake is the major factor that influences both the body weight gain and feed efficiency in meat-type poultry. Because so many factors can influence feed intake, it is often difficult to correct a problem of poor feed intake unless a complete review of feed and management practices is made. Management and flock health issues are usually more likely to reduce feed intake than dietary factor...
