Abstract:
In the context of research and development, it is key to achieve accurate and reliable results. However, often to obtain these results, a large number of experiments must be performed, which can significantly extend the research time and increase computational requirements. The solution to these problems may be efficient experimental planning, which allows for a reduction in the number of trials and optimization of the process. This article provides an insight into Central Composite Design (CCD) and its use in simulation experiments. We introduce various types of CCD designs, such as CCC (Cent

Abstract:
Missing observations in an experimental design may lead to ambiguity in decision making thereby bringing an experiment to disrepute. Robustness, therefore, enables a process, not to break down in the presence of missing observations. This work constructed a modified central composite design (MCCD) from a four-variable central composite design (CCD) augmented with four center points using the leverage of a hat-matrix. The robustness of the CCD and MCCD were assessed when a design point is missing at the factorial, axial, and center points of the experiment, for a non-standard model, using the l

Abstract:
The use of loss function in studying the reduction in determinant of information matrix due to missing observations has effectively produced designs that are robust to missing observations. Modified central composite designs are constructed for non-standard models using principles of the loss function or equivalently first compound of (I ) matrix associated with hat matrix . Although central composite designs (CCDs) are reasonably robust to model mis-specifications, efficient designs with fewer design points are more economical. By classifying the losses due to missing design points in the CCD

This paper aims to examine the effectiveness of deep learning (DL), a burgeoning aspect of machine learning and artificial intelligence, in exploring input-response dependencies from observed data, especially when complex nonlinearities are present. DL has the potential to be at least as effective as, if not better than, traditional statistical techniques such as response surface methodology (RSM). To test this hypothesis, we developed DL models using Tensor flow and compared their predictions against those of well-established statistical models. Our DL models were hyper parameter tuned using

Abstract:
In response surface methodology, the central composite design is the most popular choice for fitting a second order model. The choice of the distance for the axial runs, alpha, in a central composite design is very crucial to the performance of the design. In the literature, there are plenty of discussions and recommendations for the choice of alpha, among which a rotatable alpha and an orthogonal blocking alpha receive the greatest attention. Box and Hunter (1957) discuss and calculate the values for alpha that achieve rotatability, which is a way to stabilize prediction variance of the desig

Abstract:
In many industrial experiments, completely randomized designs (CRDs) are impractical due to restrictions on randomization, or the existence of one or more hard-to-change factors. Under these situations, split-plot experiments are more realistic. The two separate randomizations in split-plot experiments lead to different error structure from in CRDs, and hence this affects not only response modeling but also the choice of design. In this dissertation, two graphical tools, three-dimensional variance dispersion graphs (3-D VDGs) and fractions of design space (FDS) plots are adapted for split-plot

Practical restrictions on randomization are commonplace in industrial experiments due to the presence of hard-to-change or costly-to-change factors. Employing a split-plot design structure minimizes the number of required experimental settings for the hard-to-change factors. In this research, we propose classes of equivalent estimation second-order response surface split-plot designs for which the ordinary least squares estimates of the model are equivalent to the generalized least squares estimates.

The process results in non-uniform distribution of temperature and plastic strain in the ring cross-section, and this in turn significantly affects the deformation behavior, microstructure, and mechanical properties.

Abstract:
Polycrystalline Diamond Compact (PDC) bit has been widely used in natural gas/oil drilling industry for its advantages such as no rotating parts, highly rate of penetration (ROP) and durability. In recent decades, the comprehensive property of PDC bit has been improved rapidly due to the scientists’ efforts. Hydraulic design of PDC bit is very important because the retention of the cuttings may dramatically decrease ROP. Most current researches focus on how blade profile and nozzle parameters affect hydraulic performance of PDC bit, but, the understanding of gauge geometrical parameters (mainl

Abstract:
Textile dyes waste can cause a big problem for the environment. Adsorption is a simple approach in treatment of textile dyes waste. On the other hand, the use of disposable adsorbents also creates production cost problems because they are less economic. Currently, research on adsorbents is forwarded to the use of biopolymers such as chitosan, chitin, and cellulose. This research studied the use of cellulose beads, made from cellulose acetate (CA) blended with polyethylene glycol 200 (PEG200), as adsorbent in removing cationic dye of methylene blue (MB).

An effective method for predicting and optimizing the thermal performance of Parallel-Plain Fin (PPF) heat sinks that satisfy given design constraints has been successfully developed in the study. The thermal and hydrodynamic performance analyses for PPF heat sinks have been conducted. The Response Surface Methodology (RSM) is applied to establish analytical models of the thermal resistance and pressure drop in terms of the design variables with a Central Composite Design (CCD) experimental design. A constrained optimization technique, Sequential Quadratic Programming (SQP), is employed to eff

Abstract This paper addresses the difficulty of the previously developed Adaptive Response Surface Method (ARSM) for high-dimensional design problems. The ARSM was developed to search for the global design optimum for computation-intensive design problems. This method utilized the Central Composite Designs (CCD), which resulted in an exponentially increasing number of required design experiments. In addition, the ARSM generates a complete new set of CCDs in a gradually reduced design space. These two factors greatly undermine the efficiency of the ARSM. In this work, the Latin Hypercube Design

Abstract:
Cold in-place recycling (CIR) involves the recycling of the asphalt portions (including hot-mix asphalt and chip, slurry, and cape seals, as well as others) of a flexible or composite pavement with asphalt emulsion or foamed asphalt as the binding agent. Full-depth reclamation (FDR) includes the recycling of the entire depth of the pavement and, in some cases, a portion of the subgrade with asphalt, cement, or lime products as binding agents. Both processes are extensively utilized in Illinois. This project reviewed CIR and FDR projects identified by the Illinois Department of Transportation (

Abstract:
To address the problems of pavement damage and fatigue cracking of orthotropic steel deck (OSD) in bridges, an innovative composite bridge deck composed of OSD with open ribs and ultra-high performance concrete (UHPC) layer was proposed. Firstly, the stress responses of fatigue-prone details in the composite bridge deck were investigated by refined two-scale finite element analysis. The results show that the rib-to-deck joint can achieve an infinite fatigue life, while the floorbeam detail of rib-tofloorbeam joint indicates finite fatigue life. Then, response surface models of stress ranges of

Full text
Abstract:
The Continuous Strength Method (CSM) is a deformation-based approach to the design of structures that enables a continuous, rational and accurate allowance for material nonlinearity. Central to the method is the application of strain limits to define the resistance of a structural member or system.The method can be applied to structures formed using different materials and manufacturing processes and can be used for steel-concrete composite design and in fire scenarios. The design method enables enhancements in structural efficiency and, unlike traditional approaches, allows the assessment of
