The discrete structures are of great importance in the application fields of mechanical, aeronautical and civil engineering. They are composed of truss, beam or lattice elements assembled together by welding or riveting in two or three dimension. Such str... see more

The topological models for longitudinal and torsional oscillations of rod structures with various concentrated inclusions in distributed mass, stiffness of elastic medium and rod stiffness are done. The high efficiency of application of theory of graphs a... see more

The behavior of reinforced concrete elements is complex due to the nature of the concrete that is weak in tension. Among these complex issues are the initial cracking and crack propagation of concrete, and the bond-slip phenomenon between the concrete and... see more

The present paper seeks to enhance the potential damage detention and location of the discrete wavelet transform (DWT) in a thin laminated composite damaged by a signal derived from vibration modes. The DWT-1D is used to spatially identify (x-y plane) the... see more

For graphs there exists a strong connection between spectral and combinatorial expansion properties. This is expressed, e.g., by the discrete Cheeger inequality, the lower bound of which states that ?(G)=h(G), where ?(G) is the second smallest eigenvalue ... see more

From the perspective of modern cognitive science the conceptual metaphor reflects the mental aspect of cognition and creation of a new conception of the world. Therefore, numerous researchers in the area of conceptual metaphor explored it as the understan... see more

Context. The matrix notation is used to formalize the subject area within the framework of the algebraic approach. Effective computation of the discrete cosine transforms uses the reduction of a harmoni? basis to a block-cyclic matrix structure with the s... see more

Actuality. Discrete cosine transforms provide high efficiency of applications in modern information processing facilities. After all, the computation of forward and reverse transforms in the real field is especially important for the effective solution of... see more
