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 ...

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...

We present particle-based simulations and a continuum theory for steady rotating flocks formed by self-propelling particles (SPPs) in two-dimensional space. Our models include realistic but simple rules for the self-propelling, drag, and interparticle interactions. Among other coherent structures, in particle-based simulations we find steady rotating flocks when the velocity of the particles la...

Granulocytic Ehrlichia infection in sheep is common in Norway in areas with Ixodes ricinus. In this study, 2 sheep flocks that had been grazing on I. ricinus infested pastures the previous season, were blood sampled after being housed indoors for nearly 6 months during wintertime. Thirty animals from each flock were examined for granulocytic Ehrlichia infection in the peripheral blood by blood ...

Early work on natural language database query processing focused on theories of compositional semantics. Recent work concentrates on the translation of NL queries to SQL where semantics is primarily used in an ad hoc manner to guide syntactic translation. Here, we argue that there remains a need for an efficiently-implementable denotational semantics for NL DB queries, and show how this can be ...

(✓ 1 ✓ 2 ) := F ( ̄ ✓)(✓ 1 ✓ 2 ) (17) Since μ̇ > 0 and min (V ) > 0, we have (✓ 1 ✓ 2 ) 0 (G(✓ 1 ) G(✓ 2 )) (✓ 1 ✓ 2 ) 0 (V )(✓ 1 ✓ 2 ) > 0 for any ✓ 1 6= ✓ 2 . Hence, G(✓) is an injection from Rd to Rd, and so G 1 is a well-defined function. Consequently, (15) has a unique solution ˆ ✓ = G (Z). Let us consider an ⌘-neighborhood of ✓⇤, B⌘ := {✓ : k✓ ✓⇤k  ⌘}, where ⌘ > 0 is a constant that will ...

Flock Fibers In article number 2100766 by Jingwei Xie and co-workers, a new technique for electrostatic flocking is used to create anisotropic structures surfaces regenerative medicine applications. Using this method, electrospun nanofiber mats, 3D-printed meshes, tubes are surface-coated with flock fibers. Such materials evaluated in vitro vivo show promise as tissue engineering scaffolds.

The research dealt with the study of productive and economic performance broiler farms in Diyala Governorate - Iraq for 2020 production season, through a questionnaire conducted group breeders, whose number was (35) breeders out total of( 360) products, they were randomly selected order to know status production, costs efficiency Farm management, multivariate productivity function model value u...

We extend some of the theory of flocks of a finite quadratic cone to the infinite case and give some examples. One of the results we prove is that a generalized quadrangle is coming from a flock if and only if all derivations of the flock are well defined.

There has been much research done on single-flock flocking Shaw (1975), Partridge (1984), Partridge (1982), Okubo (1986), Reynolds (1987), Vicsek et al. (1995), Toner & Tu (1998), Shimoyama et al. (1996), Mogilner & Edelstein-Keshet (1999), Helbing et al. (2000), Vicsek (2001), Parrish et al. (2002), Olfati-Saber (2006), but none done on multi-flock flocking Gazi & Fidan (2007). One might ask, ...
