Computational modeling of immune system of the fish for a more effective vaccination in aquaculture

Motivation: A computational model equipped with the main immunological features of the sea bass (Dicentrarchus labrax L.) immune system was used to predict more effective vaccination in fish. The performance of the model was evaluated by using the results of two in vivo vaccinations trials against…

Effects of collisions against thermal impurities in the dynamics

Wake flow past a plate with spoiler II: Gravity effects

The effects of transverse gravity on steady flow past a split plate are investigated, by adopting the wake model proposed in the preceding paper (I). The existence and uniqueness of the solution as well as the convergence of an iteration process involving the free streamlines are proved for large…

Duality in matrix lattice Boltzmann models

Fluctuations around mean walking behaviors in diluted pedestrian flows

Understanding and modeling the dynamics of pedestrian crowds can help with designing and increasing the safety of civil facilities. A key feature of a crowd is its intrinsic stochasticity, appearing even under very diluted conditions, due to the variability in individual behaviors. Individual…

Viscoelastic Fizhugh-Nagumo models

An extended Fitzhugh-Nagumo model including linear viscoelasticity is derived in general and studied in detail in the one-dimensional case. The equations of the theory are numerically integrated in two situations: (i) a free insulated fiber activated by an initial Gaussian distribution of action…

Inference of gene networks-application to Bifidobacterium

Motivation: The reliable and reproducible identification of gene interaction networks represents one of the grand challenges of both modern molecular biology and computational sciences. Approaches based on careful collection of literature data and network topological analysis, applied to…

Effects of Forcing in Three-Dimensional Turbulent Flows

We present the results of a numerical investigation of three-dimensional homogeneous and isotropic turbulence, stirred by a random forcing with a power-law spectrum, Ef(k)~k3–y. Numerical simulations are performed at different resolutions up to 5123. We show that at varying the spectrum slope y,…

Experimental and numerical investigation of propeller loads in off-design conditions

The understanding of the performance of a propeller in realistic operative conditions is nowadays a key issue for improving design techniques, guaranteeing safety and continuity of operation at sea, and reducing maintenance costs. In this paper, a summary of the recent research carried out at CNR-…

Time-splitting schemes and measure source terms for a quasilinear relaxing system
