    This research had the objective of developing a model which describes the way that a flock of broilers from 17 to 24 days old walked in the region around the feeder, for better understanding their feeding behavior. The model takes into consideration the area occupied by the birds, their age and environmental variables such as ambient temperature, relative humidity and light intensity. Results showed that almost all variables contribute to reducing the movement, except the illuminance, but the ambient temperature is the one that mostly affect the response variable which was the movement of the birds, followed by age, relative humidity and the amount of area occupied by the broilers.335341Aydin, A., Cangar, O., Eren Ozcan, S., Bahr, C., Berckmans, D., Application of a fully automatic analysis tool to assess the activity of broiler chickens with different gait scores (2010) Computers and Electronics in Agriculture, 73, pp. 194-199Bokkers, E.A.M., Koene, P., Rodenburg, T.B., Zimmerman, P.H., Spruijt, B.M., Working for food under conditions of varying motivation in broilers (2004) Animal Behaviour, 68 (1), pp. 105-113Cahaner, A., Pinchasov, Y., Nir, I., Effects of dietary protein under high ambient temperature on body weight, breast meat yield and abdominal fat deposition on broiler stock differing in growth rate and fatness (1995) Poultry Science, 74, pp. 968-975Curto, F.P.F., Nääs, I.A., Pereira, D.F., Salgado, D.D., Estimativa do padrão de preferência térmica de matrizes pesadas (frango de corte) (abstract in English) (2007) Revista Brasileira de Engenharia Agrícola e Ambiental, 11 (2), pp. 211-216FAWC - Farm Animal.

    The turbulent dissipation rate from PIV measurements

    No full text
    The result of a particle-image velocimetry (PIV) measurement is a velocity field averaged over interrogation windows. This severely affects the measurement of small-scale turbulence quantities when the interrogation window size is much larger than the smallest length scale in turbulence. A direct measurement of the dissipation rate demands the measurement of gradients of the velocity field, which are now underestimated because the small-scale motion is not resolved. A popular procedure is to relate the statistical properties of the measured, but underresolved gradients to those of the true ones, invoking a large-eddy argument [3]. We show that the used proportionality constant, the Smagorinsky constant, should depend on the window overlap, on the used elements of the strain tensor, and on the way in which derivatives are approximate

    How the dispersion of a droplet cloud depends on its initial size

    No full text
    A cloud of droplets evolves under the influence of strong turbulence. The droplets are made from a phosphorescent fluid. From this cloud we select at t = 0 a narrow line by exciting the droplets with a UV laser, which causes them to glow for a few milliseconds. The dispersion of this line is followed in time using a fast intensified camera. A large range of droplet sizes (Stokes number St) was measured. It appears that lines with St \approx 1 disperse faster than a line of fluid tracers. Lines of droplets which are narrowest initially, spread fastest

    No full text
    AbstractIn this paper we provide a characterization of second order fully nonlinear CR invariant equations on the Heisenberg group, which is the analogue in the CR setting of the result proved in the Euclidean setting by A. Li and the first author in Li and Li (2003) [21]. We also prove a comparison principle for solutions of second order fully nonlinear CR invariant equations defined on bounded domains of the Heisenberg group and a comparison principle for solutions of a family of second order fully nonlinear equations on a punctured ball

    The Potentials of Recommender Systems Challenges for Student Learning

    No full text
    Increasingly, educators make use of learning-by-doing approaches to teach students of STEM programmes the skills that they need to become successful in careers in research and development. However, we argue that the technical challenges addressed in these programmes are often too limited and therefore do not support the students in gaining the more advanced skill sets required to thrive in our technology-oriented economy. We therefore suggest to incorporate realistic and complex challenges that model real-world problems faced in industrial settings. Focusing on the domain of recommender systems, we see potentials in embedding recommender systems challenges to enhance student learning to teach students the skills required by modern data scientists

    Ulaskom Republike Hrvatske u Europsku Uniju održivo poslovanje postaje sve značajnije, ali i krucijalno za daljnji razvoj gospodarstva i poslovanja poduzeća. Osim regulativnog značaja, posebnu pažnju održivom poslovanju pružaju razni stakeholderi i investitori, odnosno shareholderi. Razlog navedenom očita se u činjenici kako se poslovanje reflektira ne samo kroz različite indikatore performansi koherentnima financijskim pokazateljima, već i u problematici poslovanja svedenih i na nefinancijske pokazatelje nužnima za nastavak nevolatilnog poslovanja (ljudski kapital, proizvodni procesi i tehnologije, organizacijska kultura, briga za okoliš itd.). Koncept održivog poslovanja, iako s bogatom poviješću, konkretnije započinje 1987. godine kada je u izvješću Our Common Future (Brundtland, 1987.) univerzaliziran te doživljava konstantne preinake i modifikacije, posebno u posljednjem desetljeću kada važnost koncepta raste zbog alarmantnih podataka praktički vezanih uz opstanak ljudske vrste, ali i preusmjerava na konkurentsku prednost poduzeća. Stoga, autor ovog rada će stvoriti jedinstveni okvir koji omogućuje analizu održivosti poslovanja poduzeća i analizirati proces adaptacije održivosti poduzeća NEXE d.d. kao predstavnika industrije građevinskog materijala u Republici Hrvatskoj. Rad se primarno bazira na kvalitativnim podacima dobivenim kroz prikupljenu međunarodnu literaturu visokog kredibiliteta, akademskim člancima i drugim komplementarnim izvorima te službenim dokumentima poduzeća NEXE d.d.With the accession of the Republic of Croatia to the European Union, sustainability in business becomes increasingly important, but also crucial for the further development of the economy and business operations. Apropos of regulatory importance, special attention is paid to sustainable business by various stakeholders and investors, i.e. shareholders. The reason for the above can be seen in the fact that business is reflected not only through the lens of various performance indicators coherent with financial indicators, but also in the issue of business reduced to non-financial indicators necessary for the continuation of non-volatile business (human capital, production processes & technologies, organizational culture, care for the environment, etc.). The concept of sustainable business, although with a rich history, more concretely begins in 1987. when it was universalized in the report Our Common Future (Brundtland, 1987.) and it experienced constant changes and modifications, especially in the last decade when the importance of the concept grew due to alarming data practically related to the survival of human species, but it also got redirected as a competitive advantage of the company. Therefore, the author of this study will create a unique framework that enables the analysis of a company's operations sustainability and the analysis of the process of adaptation to the sustainability of the company NEXE d.d. as a representative of the construction material industry in the Republic of Croatia. The study is primarily based on qualitative data obtained through collected international literature of high credibility, academic articles and other complementary sources and official documents of the company NEXE d.d.
