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

Context. A method of efficient computation of DFT using cyclic convolutions for sizes of integer power of two has been considered.The further development of Winograd Fourier transform algorithm based on a hashing array has been proposed. The research obje... see more

Actuality. Ensuring the efficiency and versatility of modern media for processing visual information requires the development ofvarious methods for the effective implementation of the discrete cosine transform. In accordance with the requirements of moder... 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

The development of 5G technology is expected to result in high data rate communication, low power consumption and larger network capacity. Microstrip antenna is an antenna that can support 5G technology because it can work at high frequencies but has the ... see more

Technological developments in the field of telecommunications are experiencing rapid progress, especially the presence of 5G technology as a fifth generation cellular communication system that has many advantages at the World Radiocommunication Conference... see more

Hybrid system is one way in saving the use of petroleum fuels with solar power generating systems apply settlement in Semujur island where it is currently available diesel generator in operation for 3 hours/day with an  average power in each house of... see more

The use of resistivity meters to model subsurface conditions is widespread. However, commercial instruments are mostly limited to conventional configurations, such as Wenner, Schlumberger, and dipole-dipole. Moreover, we cannot modify the program on the i... see more

The hierarchical CuCo2O4-Ni(OH)2 core-shell nanowire arrays on Ni foam were fabricated using facile and cost-effective two-step hydrothermal synthesis. The growth of CuCo2O4 nanowires was developed on Ni foam as the apposite basis of the conductive scaffo... see more
