After comprehensive peer review only 11 out of 35 submitted papers have been accepted for final publication where the authors are from geographically distributed countries (USA, China, UK, Japan, South Africa, Egypt, Romania, Iran, Pakistan, Cameroon, and Saudi Arabia). In applications, the functions usually denote the physical quantities whereas the derivatives denote their rates of alteration, and the differential equation represents a relationship between the two. 1) Differential equations describe various exponential growths and decays. In the paper “A Comparative Study on Evaluation Methods of Fluid Forces on Cartesian Grids,” T. Nonomura and J. Onishi proposed a simple method for evaluating the forces acting on flows around bodies in the immersed boundary scenario. Such models are described by several constitutive relations as opposed to one, and as a result they have found wide range of applications in many areas of engineering and sciences, such as mechanical engineering, for example, in solid mechanics; aerospace engineering, for example, in aerodynamics; geophysical/astrophysical phenomena, for example, in weather-forecasting and space-exploration; and biomedical and health sciences, for example, in infectious disease control. The analysis of the thickness ratio shows difference between the classical K-L theory and N-T model when the ratio is greater than 0.099. Consider the I-V characteristic of capacitors and inductors (derivatives and integrals). We hope that the scientists who are working in the same regime not only will enjoy this special issue but would also appreciate the efforts devoted to it by the entire team. For some dielectric materials the volumetric body force is zero and the deformation due to the pressure forces is obtained using Navier’s equation for the linear elasticity at steady state.

However, recent advances made by the guest editors in the application of differential equations in the simulation and modeling of fluids, and particularly in the rheological characteristics of fluids, have motivated us to consider this special issue. We received a total of 35 submissions for possible publication. Due to vast range of application the investigations on this special issue were still scant. 4) Movement of electricity can also be described with the help of it. This book covers a very broad range of problems, including beams and columns, plates, shells, structural dynamics, catenary … TYPES OF DIFFERENTIAL EQUATION: ODE (ORDINARY DIFFERENTIAL EQUATION): An equation contains only ordinary derivates of one or more dependent variables of a single independent variable. We tried to focus on material that either advances the state-of-the-art of experimental, numerical, and theoretical methodologies or extends the bounds of existing methodologies to new contributions in mechanical sciences. The fully coupled nonlinear systems describing the total mass, momentum, thermal energy, mass diffusion, and microorganisms equations are reduced to a set of ordinary differential equations via a set of new similarity transformations. differential equations. It became an efficient tool for solving nonlinear problems which are formulated in terms of ordinary or partial differential equations. Review articles are excluded from this waiver policy.

Roles of melting parameter , CuO–H2O volume fraction , Hartmann number (Ha), and Rayleigh (Ra) number are depicted in outputs. Several verifications have been applied. Registered in England & Wales No. The applied electric field can be obtained by calculating these shifts. It should be noted that this difficulty is caused by the immersed boundary methods themselves and the present idea using the staircase integration does not have difficulty. This reflects the high impact of the proposed topic, the academic standings of guest editors, and well organization of journal’s Editorial Board of this special issue. Recently, the Lie symmetry analysis has been widely applied in different areas of mathematics, mechanics, physics, and applied sciences. The Laplace transform is denoted byL{f(t) }has it function f(t) with t (t> 0) that transforms it to a function f(s) with a real argument s.

This second of two comprehensive reference texts on differential equations continues coverage of the essential material students they are likely to encounter in solving engineering and mechanics problems across the field - alongside a preliminary volume on theory. For nonlinear problems, it is mostly difficult to obtain closed-form solutions. Even a little increment of the ratio may cause higher variance between considering and not considering the rotary mass moment of inertia, especially for the high natural frequency. Differential equations have wide applications in various engineering and science disciplines. We present examples where differential equations are widely applied to model natural phenomena, engineering systems and many other situations. Level-of-Service Based Hierarchical Feedback Control Method was applied to control the crowd of a hall and the comparison of the simulation results in the controlled and uncontrolled scenarios shows that the proposed HFCM has the capability to suggest the optimal link inflows and walking speeds in real time to meet the LOS requirement. 1.I NTRODUCTION The Differential equations have wide applications in various engineering … Recent Advances in the Application of Differential Equations in Mechanical Engineering Problems, Department of Mathematics & Statistics, IIUI, Islamabad, Pakistan, University of California, Riverside, CA, USA, Academy of Romanian Scientists, 050094 Bucuresti, Romania, Department of Mechanical Engineering, Babol Noshirvani University of Technology, Babol, Iran. In order to fill this gap, researchers were invited to contribute original research and review articles. A survey is presented on the applications of differential equations in some important electrical engineering problems. The error sources in the proposed implementation are sourced from (1) the surface area vector of the staircase body shape and (2) the approximated shear stress. Differential equations arising in mechanics, physics, engineering, biological sciences, economics, and other fields of sciences are classified as either linear or nonlinear and formulated as initial and/or boundary value problems. As a result, the accuracy of the proposed mesh-based scheme has been proven to be comparable to that of the polygon-based scheme, which is commonly adopted in straightforward implementation. An introduction to the Mathieu equation is presented in general terms and examples have boon worked out for a number of electrical analogues and in this process the transformation of the Mathieu equation into Hill's equation is also discussed, The mechanism of generation of sub-harmonics is discussed by solving the Mathieu equation in non-linear form. It is observed that adding magnetic field makes the temperature gradient reduce due to domination of conduction mechanism in high Hartmann number.
