Performance Evaluation of Wet Paving Concrete Incorporating Ternary Blends of Alluvial Tuff and Limestone Aggregates Using Simplex Centroid Mixture Method Open
Incorporating the blends of aggregates from local quarries is inevitable for sustainable construction of concrete structures. In the present study, the performance of wet paving concrete (WPC) made with ternary blends of alluvial tuff (AF.…
Kaolin-based stable colloidal nano-silica: Peptization factors and stability assessments via designed experiments Open
This study aims to synthesize stable colloidal silica via the peptization method as a green and low-cost route. It is crucial to adopt a proper synthesis procedure and choose an appropriate raw material. To achieve this purpose, kaolin was…
Application of Cellular Automata in Bi-Objective Operation of Multi Reservoir Systems Open
Optimal operation of multi-reservoir systems is one the most challenging problems in water resource management due to their multi-objective nature and time-consuming solving process. In this paper, Multi-Reservoir Parallel Cellular Automat…
Optimal hydropower operation of multi-reservoir systems: hybrid cellular automata-simulated annealing approach Open
Hydropower operation of multi-reservoir systems is very difficult to solve mostly due to their nonlinear, nonconvex and large-scale nature. While conventional methods are long known to be incapable of solving these types of problems, evolu…
Extension of the Hybrid Ant Colony Optimization Algorithm for Layout and Size Optimization of Sewer Networks Open
In this paper, the incremental solution building capability of Ant Colony Optimization Algorithm (ACOA) is exploited using a Tree Growing Algorithm (TGA) augmented with the efficiency of Nonlinear Programming (NLP) methods leading to a hyb…
The Psychosocial Impact of Prison Culture on Black Women Employees Open
This article discusses the effect of organisational culture on black women Prison Service employees’ psychosocial experience, and examines how the specificities of prison culture(s) affects this employee group.\nThe author examines how bla…
Collocated Mixed Discrete Least Squares Meshless (CMDLSM) method for solving quadratic partial differential equations Open
In this paper, a Collocated Mixed Discrete Least Squares Meshfree (MDLSM) method is proposed and used for efficient solution of engineering problems. Background mesh is not required in the MDLSM method; hence the method is a truly meshfree…
An Adaptive Relaxed Cellular Automata Method for Reliability-Based Hydropower Operation of Reservoirs Open
This paper presents a novel Cellular Automata approach for solution of reliability-based reservoir hydropower operation problems. The method is based on the observation that a low value of the penalty parameter would lead to partial enforc…
Mixed discrete least squares meshless method for solving the linear and non-linear propagation problems Open
A Mixed formulation of Discrete Least Squares Meshless (MDLSM) as a truly meshfree method is presented in this paper for solving both linear and non-linear propagation problems. In DLSM method, the irreducible formulation was deployed whic…
RPIM and RPIM-MLS based MDLSM method for the solution of elasticity problems Open
One of the main difficulties in the development of meshless methods using the Moving Least Squares approximation, such as Mixed Discrete Least SquaresMeshless (MDLSM) method, is the imposition of the essential boundary conditions. In this …
Arc Based Ant Colony Optimization Algorithm for optimal design of gravitational sewer networks Open
In this paper, constrained and unconstrained versions of a new formulation of Ant Colony Optimization Algorithm (ACOA) named Arc Based Ant Colony Optimization Algorithm (ABACOA) are augmented with the Tree Growing Algorithm (TGA) and used …
Improving the Efficiency of Cellular Automata for Sewer Network Design Optimization Problems Using Adaptive Refinement Open
This paper introduces an adaptive procedure to improve the efficiency of a two phase simulation-optimization cellular automata algorithm recently proposed by the authors for the optimal design of household sewer networks. In the proposed m…
Fuzzy linear system of the form $\tilde{A}_{1} X\Theta_{gH}\tilde{A}_{2} X=\tilde{b}$ Open
In this paper, we shall propose a new method to obtain solutions of a fully fuzzy linear system (FFLS) based on concept of generalized Hakuhara difference. FFLS of the form $\tilde{A}_{1} X=\tilde{A}_{2} X+\tilde{b}$ is converted to $\tild…
