Efficient mode shape extraction of fluid-structure systems is of particular interest in engineering. An efficient modified version of unsymmetric Lanczos method is proposed in this paper. The original unsymmetric Lanczos method was applied to general form of unsymmetric matrices, while the proposed method is developed particularly for the fluid-structure matrices. The method provides us with si...

ABSTRACT Stellar bars and spiral arms coexist co-evolve in most disc galaxies the local Universe. However, physical nature of this interaction remains a matter debate. In work, we present set numerical simulations based on isolated galactic models aimed to explore how bar properties affect induced structure. We cover large combination properties, including length, axial ratio, mass, rotation ra...

Soot aggregation with simultaneous surface growth was modeled using a dynamic Monte-Carlo method. Simulations were performed in the environment of a 10 bar laminar premixed flame of ethylene. The Monte-Carlo algorithm begins in the particle inception zone and constructs soot particles via ensemble-averaged collisions between small spheres and deposition of gaseous species on the sphere surfaces...

Clathrin-mediated endocytosis is an essential process that forms vesicles from the plasma membrane. Although most of the protein components of the endocytic protein machinery have been thoroughly characterized, their organization at the endocytic site is poorly understood. We developed a fluorescence microscopy method to track the average positions of yeast endocytic proteins in relation to eac...

Spurious eigensolutions in the boundary integral equation (BIE) or boundary element method (BEM) for doublyconnected domain problems, the eccentric and annular membranes, are studied analytically and numerically in this paper. For the mathematical analysis, we employ the null-field integral equation, the degenerate kernels and the Fourier series to prove the existence of spurious eigensolutions...

Objectives: Research examining how emotional intelligence (EI) relates to the performance of athletes has been conducted using various EI measures including the Bar-On Emotional Quotient Inventory (EQ-i; Bar-On, 1997), but no one has investigated the factor structure of the EQ-i in the area of sport psychology. The current study explored the dimensional structure and factorial validity of the E...
