The existence and uniqueness of pseudo-almost periodic functions (PAP) solutions was analyzed. The usefulness of the analysis is discussed. The notion of almost periodicity and pseudo-almost periodicity was also discussed ...

We consider positive invertible Lamperti operators Tf(x)=h(x)Φf(x) such that Φ has no periodic part. Let An,T be the sequence of averages of T and MT the ergodic maximal operator. It is obvious that if MT is bounded on some Lp, 1

Polymerization was an early focus for periodic operation. Ray (1968) and Laurence and Vasudevan (1968) observed that the molecular weight distribution of a polymer may be modified by periodically varying the concentrations ...

This paper is devoted to the study of the class of continuous and bounded functions f : [0, infinity] -> X for which exists omega > 0 such that lim(t ->infinity) (f (t + omega) - f (t)) = 0 (in the sequel called S-asymptotically ...

Temporal variations of the liquid holdup in a mini-pilot scale trickle bed reactor cold-mockup, induced by an ON-OFF liquid flow modulation strategy of operation, are explored at different axial positions. The reactor is ...

Small non-autonomous perturbations around an equilibrium of a nonlinear delayed system are studied. Under appropriate assumptions, it is shown that the number of T-periodic solutions lying inside a bounded domain Ω ⊂ R N ...

Periodic operation was investigated for the hydrogenation of aplpha-methylsyrene to cumene over 0.5% Pd on alumina spheres. The effect of several variables such as gas flow rate, gas and liquid composition, and liquid feed ...

In this work we study the existence and uniqueness of pseudo-almost periodic solutions for a first-order abstract functional differential equation with a linear part dominated by a Hille-Yosida type operator with a non-dense ...
