Conventional non-reinforced concrete is a brittle material with a low tensile strength and low strain capacity. To improve these mechanical properties of concrete, fibers have been used in the last decades in structural engineering applications in Colombi... see more

The promising development of magnetic sensors in biomedical field demands an appropriate level of understanding of the magnetic properties of the materials used in their fabrication. To date only few of the types of magnetic materials are encountered wher... see more

This paper describes the design, evaluation, and implementation of a compensation scheme for a measurement voltage transformer (VT) using the hysteresis characteristics of the core. The error of a VT is caused by the primary winding voltage and secondary ... see more

This paper reports the results of experimental studies into determining mechanical properties (elastic and dissipative) at the shear of the material of a pressure fire hose of the "T" type with the internal diameter of 77 mm using torsion tests. Duri... see more

Experimental research into determining the mechanical properties (elastic and dissipative) of the pressure fire hose of type «T» with an inner diameter of 66 mm under conditions of static load were presented. The experiment was conducted on the experiment... see more

In the present work, thin films of Cr/NiO/Ni are deposited on glass substrates using RF magnetron sputtering technique. The uniformity and homogeneity of the prepared films were controlled by varying the power of the source, the target-substrate distance ... see more

Mesoporous pure TiO2 (M-TiO2) and mesoporous-vanadium-doped TiO2 (M-V-doped TiO2) were successfully synthesized via a facile and simple reflux technique. The purpose of this research was to study the effect of vanadium dopant on the physicochemical proper... see more

Three tests using photometrical analysis were completed for crack closure estimation and covered at present paper. Constant and variable amplitude loading cases are both analyzed. Inadequacy of contemporary crack closure estimation models to explain resul... see more
