power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
Abstract The transverse vibrations of an extended cylindrical underground structure under the action concentrated forces changing according to a harmonic law are considered. problem rod interacting with elastic homogeneous medium was solved by Fourier method. Approximate solutions obtained using method compensating loads. influence soil conditions and geometrical dimensions structure, location ...
Carothers and Flory established the fundamental principles of homogeneous two-component polycondensation reactions by which a variety of commonly used polymers such as polyesters and polyamides (nylons) are synthesized even now. One of the most critical factors to achieve a high degree of polymerization is a strict adherence of stoichiometric balance of the two components. An imbalanced ratio o...
