Single Facility Goal Location Problems with Symmetric and Asymmetric Penalty Functions

Aria ‎Soleimani ‎Koorandeh; Jafar Fathali; Ahmad ‎Nezakati; Morteza Nazari

Volume 4, Issue 1 , July 2019, Pages 1-14

https://doi.org/10.30473/coam.2020.51447.1136

Abstract
  Location theory is an interstice field of optimization and operations research‎. ‎In the classic location models‎, ‎the goal is finding the location of one or more facilities such that some criteria such as transportation cost‎, ‎the sum of distances passed by clients‎, ‎total ...  Read More

Finding the Optimal Place of Sensors for a 3-D Damped Wave Equation by using Measure Approach

Hajar Alimorad; Alireza Fakharzadeh Jahromi

Volume 4, Issue 1 , July 2019, Pages 15-36

https://doi.org/10.30473/coam.2020.48871.1126

Abstract
  In this paper‎, ‎we model and solve the problem of optimal shaping and placing to put sensors for a 3-D wave equation with constant damping in a bounded open connected subset‎ ‎of 3-dimensional space‎. ‎The place of sensor is modeled by a subdomain‎ ‎of this region ...  Read More

Solution of Fractional Optimal Control Problems with Noise Function Using the Bernstein Functions

Ali Nemati; Ali Alizadeh; Fahime Soltanian

Volume 4, Issue 1 , July 2019, Pages 37-51

https://doi.org/10.30473/coam.2020.33909.1078

Abstract
  This paper presents a numerical solution of a class of fractional optimal control problems (FOCPs) in a bounded domain having a noise function by the spectral Ritz method‎. ‎The Bernstein polynomials with the fractional operational matrix are applied to approximate the unknown functions‎. ...  Read More

Global Forcing Number for Maximal Matchings under Graph Operations

Mostafa Tavakolli

Volume 4, Issue 1 , July 2019, Pages 53-63

https://doi.org/10.30473/coam.2020.51754.1138

Abstract
  Let $S= \{e_1,\,e_2‎, ‎\ldots,\,e_m\}$ be an ordered subset of edges of a connected graph $G$‎. ‎The edge $S$-representation of an edge set $M\subseteq E(G)$ with respect to $S$ is the‎ ‎vector $r_e(M|S) = (d_1,\,d_2,\ldots,\,d_m)$‎, ‎where $d_i=1$ if $e_i\in M$ and $d_i=0$‎ ...  Read More

Development of RMPC Algorithm for Compensation of Uncertain Time-Delay and Disturbance in NCS

Farshid Pouralizadeh Moghaddam; Hossein Gholizade Narm

Volume 4, Issue 1 , July 2019, Pages 65-81

https://doi.org/10.30473/coam.2020.51398.1135

Abstract
  In this paper‎, ‎a synthesis method based on robust model predictive control is developed for compensation of uncertain time-delays in networked control systems with bounded disturbance‎. ‎The proposed method uses linear matrix inequalities and uncertainty polytope to model uncertain ...  Read More

Stable Rough Extreme Learning Machines for the Identification of Uncertain Continuous-Time Nonlinear Systems

Ghasem Ahmadi

Volume 4, Issue 1 , July 2019, Pages 83-101

https://doi.org/10.30473/coam.2020.51511.1137

Abstract
  ‎Rough extreme learning machines (RELMs) are rough-neural networks with one hidden layer where the parameters between the inputs and hidden neurons are arbitrarily chosen and never updated‎. ‎In this paper‎, ‎we propose RELMs with a stable online learning algorithm for the identification ...  Read More
