Application of quantum technology in radars
In this paper, the use of quantum technology in the radar system and the advantages of these radars as compared to classical radars have been analyzed. In the beginning, briefly, we present the basic structure of the theory of quantum electrodynamics, and then the role of photon in this theory and photon interactions is presented. In the next step, the most general form of the quantum radar cr...
متن کاملHuge opportunities for industry of nanofibrous concrete technology
In spite of the fact that cementitious and concrete materials are mainly used on a large scale and in huge quantities for roads, dams, bridges and building constructions, the mechanical behavior of these materials depends to a great extend on structural elements and phenomena which are effective on a micro and nanoscale. Although this is well known by researchers, material producers and enginee...
متن کاملNovel sensor technology for NDE of concrete
This paper describes the application of a novel actuator/sensor technology for the generation and detection of stress waves in structural materials like concrete. The technology is aimed at developing an innovative NDE scheme based on the generation of highly nonlinear solitary waves (HNSWs). HNSWs are stress waves that can form and travel in highly nonlinear systems (i.e. granular, layered, fi...
متن کاملTowards concrete application of electronic signature
Even though the theory behind digital signatures is fully understood and the related cryptographic methods have proved the efficiency in deploying security services, concrete application of digital signature to real electronic documents is still hindered by the lack of standards. In particular, we lack standards for the format of the data to be signed, the format of the signature itself and the...
متن کاملApplication of Nanotechnology in Self-Compacting Concrete Design
In this study, first, different mix design of four types of Self-Compacting Concrete (SCC), 1. SCC consisted of only nanosilica, 2. SCC included only microsilica, 3. SCC consisted of both microsilica and nanosilica and 4. SCC without microsilica and nanosilica called as control mix, were casted and tested to find out the values of the Slump Flow, L-Box and 7 and 28 days compressive strength. Th...
