One of the modern science challenges is finding a bridge between the real world outside the observer and the observer's inner world. In “Soft Logic” we suggested a constructive model of bridging the two worlds by defining, on the base of the zero axis, a new kind of numbers, which we called ‘Soft Numbers’.</p> <p>Inspired by the investigation and visualization of fractals by Mandelbrot, within the investigation of the dynamics of some special function of a complex variable on the complex plane, we investigate in this paper the dynamics of soft functions on the plane strip with a special coordinate system. The recursive process that creates this soft dynamics allows us to discover new dynamics sets in a plane.</p> Moshe Klein, Oded Maimon Copyright (c) 2020 Moshe Klein, Oded Maimon http://creativecommons.org/licenses/by/4.0 https://rajpub.com/index.php/jam/article/view/8531 Sat, 04 Jan 2020 10:49:05 +0000 An Application of Computational Fluid Dynamics to Optimize Municipal Sewage Networks; A Case of Tororo Municipality, Eastern Uganda. https://rajpub.com/index.php/jam/article/view/8345 <p>Two-phase pipe flow is a common occurrence in many industrial applications such as sewage, water, oil, and gas transportation. Accurate prediction of liquid velocity, holdup and pressure drop is of vast importance to ensure effective design and operation of fluid transport systems. This paper aimed at the simulation of a two-phase flow of air and sewage (water) using an open source software OpenFOAM. Numerical Simulations have been performed using varying dimensions of pipes as well as their inclinations. Specifically, a Standard k-&nbsp;turbulence model and the Volume of Fluid (VOF) free water surface model is used to solve the turbulent mixture flow of air and sewage (water). A two dimensional, 0.5m diameter pipe of 20m length is used for the CFD approach based on the Navier-Stokes equations. Results showed that the flow pattern behaviour is influenced by the pipe diameters as well as their inclination. It is concluded that the most effective way to optimize a sewer network system for Tororo Municipality conditions and other similar situations, is by adjusting sewer diameters and slope gradients and expanding the number of sewer network connections of household and industries from 535 (i.e., 31.2% of total) to at least 1,200 (70% of total).</p> Twaibu Semwogerere, R.

Then, we present various results related to different types of measurements, domains and boundary conditions for distributed parameter systems (DPS<sub>S</sub>) in parabolic systems problem.&nbsp; The considered approach of this work is derived from Luenberger observer theory which is enable to estimate asymptotically the state gradient of the original system on a sub-region of the domain boundary &nbsp;in order that the RBAGFO-observability notion to be achieved. We also show that there exists a dynamical system for the considered system is not BAGFO-observer in the usual sense, but it may be regional RBAGFO-observer.</p> Raheam Al-Saphory, Zinah A.

We are interested in how the costs affect them and if a customer has a travel card.</p> <p>Credit card customers are shown to be 6 times more likely to use it regardless of the cost they make.<br>It is also shown that a customer is more likely to use a travel card when costs increase Through logistic regression, which gives the probability that a result is an exponential function of the independent variables, we will see how through our data we will come to very important conclusions.</p> Elmira Elmira Kushta, Gladiola Trushaj Copyright (c) 2020 Elmira Elmira Kushta, Gladiola Trushaj http://creativecommons.org/licenses/by/4.0 https://rajpub.com/index.php/jam/article/view/8557 Sat, 18 Jan 2020 10:07:30 +0000 Approximating Fixed Points of The General Asymptotic Set Valued Mappings https://rajpub.com/index.php/jam/article/view/8549 <p>&nbsp; The purpose of this paper is to introduce a new generalization of asymptotically non-expansive set-valued mapping &nbsp;and to discuss its demi-closeness principle.

In this work, an algebra is constructed, called Δ - ordered Banach algebra, we define convergent in this new space, Topological structure on&nbsp; Δ ordered Banach Algebra and prove this as Hausdorff space. Also, we define new conditions as Δ- <em>lipshtiz,, Δ-&nbsp;contraction&nbsp;&nbsp;contraction</em> , in this algebra construct, we prove this condition is the existence and uniqueness results of the fixed point. In this paper,&nbsp; we prove a common fixed point if the self-functions satisfy the new condition which is called <em>Ф-contraction.</em></p> <p>&nbsp;</p> Boushra Hussein Copyright (c) 2020 Boushra Hussein http://creativecommons.org/licenses/by/4.0 https://rajpub.com/index.php/jam/article/view/8370 Fri, 07 Feb 2020 11:00:41 +0000 New Schrödinger wave mathematics changes experiments from saying there is, to denying there is quantum weirdness https://rajpub.com/index.php/jam/article/view/8656 <div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p>With a clever new interpretation of the Schrödinger equation, those quantum experiments that allegedly prove that the quantum world is weird, no longer do so. When we approach the math from an unexpected angle, experiments that appeared to prove that time can go backwards in the quantum world, no longer say that. Experiments that appeared to demonstrate that a particle can be in two places at the same time, no longer say that. This requires that we take a counter-intuitive approach to the math, rather than a counter-intuitive approach to the quantum world. QM makes sensible assumptions and discovers that the quantum world is weird. Our math from the Theory of Elementary Waves (TEW) makes weird assumptions and discovers that the quantum world is sensible. We pay the weirdness tax up front. QM does not pay the weirdness tax and is penalized with a permanent misperception of the quantum world. This article is paired with a lively YouTube video that explains the same thing in 18 minutes: “New Schrödinger wave mathematics changes experiments from saying there is, to denying there is quantum weirdness.” That video can be found at the website ElementaryWave.com.</p> </div> </div> </div> Jeffrey Boyd Copyright (c) 2020 Jeffrey Boyd http://creativecommons.org/licenses/by/4.0 https://rajpub.com/index.php/jam/article/view/8656 Fri, 21 Feb 2020 09:53:00 +0000
