The Effect of Sterilization on Size and Shape of Fat Globules in Model Processed Cheese Samples
(University of Veterinary and Pharmaceutical Sciences in Brno, 2006-05-11)Model cheese samples from 4 independent productions were heat sterilized (117 C, 20 minutes), after the melting process and packing with an aim to prolong their durability. The objective of the, study was to assess changes ... -
Postnatal Development of the Urine Cortisol/Creatinine Ratio in the Dog
(University of Veterinary and Pharmaceutical Sciences in Brno, 2008-12-19)The objective of this study was to determine the cortisol to creatinine ratio in urine of growing puppies between birth and the age of 8 weeks. Beagle puppies (n = 14) of three litters were used. The puppies of litters 1 ... -
Stability and asymptotic properties of a linear fractional difference equation
(Springer Nature, 2012-07-23)This paper discusses qualitative properties of the two-term linear fractional difference equation with respect to its stability and asymptotics. Some consequences to the theory of Volterra difference equations are presented ... -
Meshfree methods for computational fluid dynamics
(EDP Sciences, 2012-11-20)The paper deals with the convergence problem of the SPH (Smoothed Particle Hydrodynamics) meshfree method for the solution of fluid dynamics tasks. In the introductory part, fundamental aspects of meshfree methods, their ... -
Topological structuring of the digital plane
(DMTCS, 2013-08-01)We discuss an Alexandroff topology on the digital plane having the property that its quotient topologies include the Khalimsky and Marcus-Wyse topologies. We introduce a further quotient topology of the topology discussed and ... -
Solvability of a nonlocal boundary value problem for linear functional differential equations
(Springer, 2013-08-14)In the paper, the problem on the existence and uniqueness of a solution to the nonlocal problem u'(t)=l(u)(t)+q(t), u(a)=h(u)+c is studied. They are found conditions guaranteeing the unique solvability of considered problem. -
Power functions and essentials of fractional calculus on isolated time scales
(Springer, 2013-08-23)This paper concerns with a recently suggested axiomatic definition of power functions on a general time scale and its consequences to fractional calculus. Besides a discussion of existence and uniqueness of such functions, ... -
On stochastic inlet boundary condition for unsteady simulations
(EDP Sciences, 2013-11-19)The paper deals with the stochastic generation of synthesized turbulence, which may be used for a generating of an inlet boundary condition for unsteady simulations, e.g. Direct Numerical Simulation (DNS) or Large Eddy ... -
Komprimované snímání perfúzního zobrazování v MRI
(Společnost elektrotechnického inženýrství, 2013-11-20)Perfúzní zobrazování v MRI je lékařská diagnostická metoda, kdy pacientovi podáme kontrastní látku a poté průběžně sledujeme průběh její koncentrace v postižené oblasti. Tuto závislost můžeme přibližně matematicky popsat ... -
Fredholm alternative for the second-order singular Dirichlet problem
(Springer, 2014-01-13)It is found condition guarantees the validity of the Fredholm alternative for the second-order singular Dirichlet problem. -
Fredholm's third theorem for second order singular Dirichlet problem
(Springer, 2014-03-18)There are found conditions guarantee the validity of the third Fredholm's theorem for the second-order singular Dirichlet problem. -
On the stability of some properties of partial algebras under powers
(SAV, 2014-04-01)In the paper, we study eight properties of partial algebras most of which are related to diagonality. For each of the properties, we give sufficient conditions under which this property is preserved by powers of partial algebras. -
Dual Numbers Approach in Multiaxis Machines Error Modeling
(Hindawi, 2014-06-01)Multiaxis machines error modeling is set in the context of modern differential geometry and linear algebra. We apply special classes of matrices over dual numbers and propose a generalization of such concept by means of ... -
