A complete understanding of solar radio bursts requires developing numerical techniques which can connect large-scale activities with kinetic plasma processes. As a starting point, this study presents scheme combining three different techniques: (1) extrapolation magnetic field overlying specific active region in order to derive the background field, (2) guiding-center simulation dynamics milli...

multiple traveling salesman problem (mtsp) is one of the most popular operation research problem and is known as combinatorial optimization problems. mtsp is an extension version of the famous and widely used problem named traveling salesman problem (tsp). because of its benefices in various domains, many researchers have tried to solve that, and many methods have proposed so far. mtsp is a np-...

Both the topics of Computer Aided Process Planning and Production Planning in the context of sheet metal air bending have been presented as standalone topics previously. This paper will focus on the interaction between both modules. Choices made by the CAPP-module seem to influence the possible gains that can be obtained in production planning and vice versa. The used procedures for both the CA...

In this paper, we introduce a new approach for solving the traveling salesman problems (TSP) and provide a solution algorithm for a variant of this problem. The concept of the proposed method is based on the Hungarian algorithm, which has been used to solve an assignment problem for reaching an optimal solution. We introduced a new fittest criterion for crossing over such problems, and illu...

Urban agriculture (UA) is practiced inside (intraurban) or on the outskirts (periurban) of a town or a city. While it focuses on raising food and animal crops, it includes recycling household waste and wastewater for agricultural purposes, the processing and distribution of different food and non-food products using human and material resources, products, and services that are found in the same...

The extended homogeneous balance method is used to construct exact traveling wave solutions of the Maccari system, in which the homogeneous balance method is applied to solve the Riccati equation and the reduced nonlinear ordinary differential equation. Many exact traveling wave solutions of the Maccari system equation are successfully obtained.

In this paper we study for small positive the slow motion of the solution for evolution equations of Burgers’ type with small diffusion, ut = uxx + f(u)ux , u(x, 0) = u0(x), u(±1, t) = ±1, (?) on the bounded spatial domain [−1, 1]; f is a smooth function satisfying f(1) > 0, f(−1) < 0 and ∫ 1 −1 f(t)dt = 0. The initial and boundary value problem (?) has a unique asymptotically stable equilibriu...

this article proposes a new algorithm for finding a good approximate set of non-dominated solutions for solving generalized traveling salesman problem. Random gravitational emulation search algorithm (RGES (is presented for solving traveling salesman problem. The algorithm based on random search concepts, and uses two parameters, speed and force of gravity in physics. The proposed algorithm is ...
