Directions of simulation modeling

This paper describes an investigation of fluid flow through two tandem circular cylinders using Lattice-Boltzmann Method in direct numerical simulation. The diameter ratio of two circular cylinders, D1/D2 varies from 0.5 to 1.5, and spacing ratio (L/D2) varies from 1.5 to 10, whereas the Reynolds number of 100 is considered. The numerical model is well validated by comparing the results with those obtained in the literature.

The thesis is structured as follows: In Chapter 1, the scientific literature is summarized within the scope of this study. Chapter 2 provides a comprehensive overview of the principles of the applied computational approaches in this study. Chapter 3 identifies the important residues of the LsIA/α7 nAChR complex that affect the interactions between the toxin and the membrane protein due to C-terminal carboxylation of LsIA. The effects of C-terminal modification of LsIA on interactions with α3β2 nAChR, involved in cardiovascular diseases, were also investigated in Chapter 4.

The paper proposes an approach of directly adaptive control for manipulators, which is applicable to control the robotics perturbed by time varying uncertain parameters. This approach is established based on combining the well known conventional feedback linearization method and the here in this article proposed model based online observation of uncertainties.

In recent years, cognitive relay networks (CRNs) have emerged as a fantastic trend in research. It supports the establishment of a new communication network by spectrumsharing technique. However, most papers focus on studying the performance of the dual-hop scheme. This paper evaluates the proposed multi-hop model by giving the closed-form multihop network outage (OP). Simulation verifies our derivation and discovers the impact of several related factors on the secondary outage probability.

Although the research direction on NSFD schemes for differential equations have achieved a lot ofresults shown by both quantity and quality of existing research works, real-world situations have always posednew complex problems in both qualitative study and numerical simulation aspects. On the other hand, there aremany differential models that have been established completely in the qualitative aspect but their correspondingdynamically consistent discrete models have not yet been proposed and studied

In these systems, a source node can communicate with a destination node directly or via the selected relay nodes, while relay nodes harvest energy from radio frequency for forwarding the received signal. In addition, the decode and forward (DF) protocol is applied to relay nodes, and selection combination technique is employed at the destination in order to select the best relay node. The system performance is presented by outage probability expressions over independent and identically distributed (i.i.d) Nakagami-m channel model.
