An adaptive method called constant false alarm rate (CFAR) detection is used in radar systems to pick out target echoes from the general noise. It is the job of the constant false alarm rate circuit to establish the level of confidence with which each reflected signal or echo is assumed to have come from the intended target. Most radar systems have a threshold that must be adjusted to meet a target false alarm rate (or likelihood of false alarm). In the CFAR detection method known as cell-averaging CFAR (CA - CFAR), the threshold is determined by scanning a block of cells around a cell-under-t
The main objective in this paper is to determine the fatigue life of light rail transit in urban network through bulk specimens. It has involve regards the fatigue failure analysis in simulation to estimate the fatigue life of UIC60 rail profile as steel with using specimen of bulk in accordance standard of ASTM E466-15. The type of tensile strength machine was performed below 250 kN in order to identify the value of ultimate tensile strength (UTS). It have based on stress levels of 20%, 30%, 40%, 50%, 60%, 70% and 80% in considering normal temperature room of 37.5°C as below values on UTS.
Precast, prestressed double tee beams are used and designed similarly to other prestressed elements. However, there are some circumstances that are specific to double tee beams, either because of how the beams or slab are made or because of how they are used. For special situations, double tee beam producers have developed design criteria and conducted in-house testing to verify that their approaches are valid. In fact, there is consistency between the many types of double tee beams available. The fundamental design requirements for double tee floor and roof systems are covered in this researc
Green chemistry is new leading approach used for bio-synthesis of metal nanoparticles that ultimately produce an eco-friendly, less-toxic, and non-hazardous nanoparticles. Plants are among available organisms (biological systems) that have been widely investigated by recent researchers for the production of nanoparticle, due to their ability to produce more stable nanoparticles with faster synthesis rate. Zinc oxide (ZnO) nanoparticles possess stable physical and chemical properties along with being non-toxic and cheaper material and hence, it is good candidate to be bio-synthesized and applie
A new electronic gas detection system is presented in this paper. It is particularly important to pay attention to electronic noses that employ several resistive sensors. Due to new materials (TiO2) or low-cost fabrication processes, new resistive sensors may be extremely valuable, and if these sensors are combined with traditional ones (SnO2), a novel instrument will be needed to manage high-value resistive sensors ranging from kilohms to ginghams. Modular hardware is proposed that uses an improved resistance-to-period converter, where sensors are powered by DC. Under the assumption of commer
