Optimal Design of RC Frames using a Modified Hybrid PSOGSA Algorithm

open access: yesArchives of Civil Engineering, 2017
The present study has been taken up to emphasize the role of the hybridization process for optimizing a given reinforced concrete (RC) frame. Although various primary techniques have been hybrid in the past with varying degree of success, the effect of ...

Predicting the Future Burden of Renal Replacement Therapy in Türkiye Using National Registry Data and Comparative Modeling Approaches

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...

Multi-objective optimization in plastic injection molding with injection and packing time

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Plastic injection molding (PIM) is one of the most important manufacturing processes for producing plastic products. The process parameters in the PIM, such as mold temperature, melt temperature, and injection pressure affect the product quality and the ...

Some Optimum Weighing Designs

open access: yesThe Annals of Mathematical Statistics, 1959
Suppose we are given $N$ objects to be weighed in $N$ weighings with a chemical balance having no bias. Let $x_{ij} = 1$ if the $j$th object is placed in the left pan in the $i$th weighing, $= -1$ if the $j$th object is placed in the right pan in the $i$th weighing, $= 0$ if the $j$th object is not weighed in the $i$th weighing. The $N$th order matrix $

Optimum Design of Penstock for Hydro Projects

open access: yes, 2015
Penstock, a closed conduit, is an important component of hydropower projects. Various methods are available for optimum design of penstock. These methods are either based on empirical relations or derived analytically by optimizing the friction loss in ...

ON OPTIMUM DESIGN OF FRAME STRUCTURES

open access: yesActa Polytechnica CTU Proceedings, 2020
Optimization of frame structures is formulated as a non-convex optimization problem, which is currently solved to local optimality. In this contribution, we investigate four optimization approaches: (i) general non-linear optimization, (ii) optimality ...

Optimum design for more effective tuned mass damper system and its application to base‐isolated buildings

open access: yes, 2014
Base‐isolated structures are vulnerable to long‐period ground motions due to resonances. The hybrid control strategy combining traditional tuned mass dampers (TMDs) with base‐isolation systems has been proved by some researchers to be effective in ...
