Numerical analysis is the study of algorithms that use numerical approximation for the problems of mathematical analysis . Numerical analysis naturally finds application in all fields of engineering and has adopted elements of scientific computations in physical sciences . The growth in computing power has revolutionized the use of realistic mathematical models in science and engineering , and subtle numerical analysis is required to implement these detailed models of the world . In recent years , fractional calculus by replacing the derivatives of classical models with fractional order derivatives is found to be a convenient and useful tool
World trends for Industry 4.0 holds tremendous potential in numerous industries to enable product customization , provide flexibility to meet new demands in real time , and produce more efficient operations . However , most routines in assessment of food quality remain highly reliant on laboratory-based examination . In remote areas , where resources are insufficient , sending specimens to analytical laboratories is challenging . In addition , the equipment used in the laboratory is expensive and bulky . Hence , there is a need for a simple , compact but robust method for identification of food quality . to describe such problems in complex dynamics .
In this research , the Lattice Boltzmann Method ( LBM ) is used to numerically simulate the natural convection heat transfer of Cu-water nanofluid in a L-shaped enclosure with curved boundaries . Three different models of curved L-shape cavity using staircase approach are simulated to perform a comparative investigation for the effects of curved boundary on fluid flow and heat transfer , which is the novel contribution of this study . The results show that the top curved boundary in curved L-shape models causes a notable increase in the Nusselt number values .
In this study , we aim to introduce a new analytical way in transition laboratory-based chemical examination to mobile platforms by merging the laser induced fluorescence ( LIF ) and CMOS camera of a smartphone . The key elements for LIF CMOS imaging involve the LED acting as illumination sources , external lenses for optical imaging , and fluorescence emission filters for light routing . The main objective of this study is to determine honey purity in comparison with the conventional method .
