Inspired by the group activities of natural swarms (e.g., a flock birds, colony ants, etc.), fleet mobile robots can be collaboratively put into work to accomplish complex real-world tasks. Depending on nature and complexity problem, multi-robot system (MRS) may need decomposed several subgroups. This paper proposes unified coordinated control scheme for networked MRSs having multiple targets. ...

Small ruminant lentivirus infections in sheep most commonly present with respiratory signs (maedi) and indurative mastitis, while primary neurological (visna) have rarely been reported Great Britain (GB). Most reports of visna describe referable to myelitis, although central associated encephalitis may feature. In this case, was diagnosed a 4-year-old ewe small pedigree flock, recently imported...

While many methods to simulate flocking behaviors have been proposed, these techniques usually only provide simplistic navigation and planning capabilities because each flock member’s behavior depends only on its local environment. In this work, we investigate how the addition of global information in the form of a roadmap of the environment enables more sophisticated flocking behaviors and sup...

A truly fruitful way to construct finite generalized quadrangles is through the detection of Kantor families in the general 5-dimensional Heisenberg group H2(q) over some finite field Fq . All these examples are so-called “flock quadrangles”. Payne (Geom. Dedic. 32:93–118, 1989) constructed from the Ganley flock quadrangles the new Roman quadrangles, which appeared not to arise from flocks, but...

In this paper, we study how and to what extent a self-organized mobile robot flock can be guided to move in a desired direction by informing some of the individuals within the flock. Specifically, we extend a flocking behavior that was shown to maneuver a swarm of mobile robots as a cohesive group in free space, avoiding obstacles. In its original form, the flock does not have a preferred direc...

Morel's disease caused by Staphylococcus aureus subsp. anaerobius was diagnosed for the first time in Poland in October 2006 in a goat flock. A second infected flock was found two months later. The course of the disease in both flocks was observed for 15-17 months. Clinical manifestation was confined to abscesses located near major superficial lymph nodes, mostly: superficial cervical, subiliac...

Data representing moving objects is rapidly getting more available, especially in the area of wildlife GPS tracking. It is a central belief that information is hidden in large data sets in the form of interesting patterns, where a pattern can be any configuration of some moving objects in a certain area and/or during a certain time period. One of the most common spatio-temporal patterns sought ...

The impact of maternal flock age and incubation on embryo metabolism was studied to understand late incubation overheating and mortality in Ross 308 embryos. Fresh broiler hatching eggs (n = 45) were obtained from commercial breeder flocks at 3 ages: Young (Y): 25 to 34 wk, Peak (P): 35 to 45 wk, Old (O): 46 to 54 wk of age), stored for 2 to 4 d at 18°C and 73% RH, then incubated for 14 d at 37...

Within the multi-disciplinary CARMA (Campylobacter Risk Management and Assessment) project it was decided to focus on evaluation of interventions in the chicken meat chain. To assess the effect of control measures on the farm we developed a model on Campylobacter transmission in Dutch broilers and broiler flocks, resulting in an estimate of the Campylobacter prevalence in broilers for slaughter...
