Abstract null null In the process in which high-density passengers need to be evacuated from a multi-exit subway station, not all the exits can be effectively utilized, and the bottlenecks near the exits are often crowded. Therefore, the utilization of different exits and the optimization of congestion at bottlenecks were investigated in this study. To alleviate the congestion of the evacuation in a large-scale and multifunctional subway station, the first underground floor of the station was di...

Abstract null null Shot peening (SP) parameters are optimized and their effects on fatigue life are investigated using a response surface methodology (RSM) for AA7B50-T7751. Three parameters (SP velocity, nozzle distance (hereafter called distance), and coverage) are optimized using the finite element method (FEM) to obtain the appropriate residual stress, average surface roughness (SR), grain-refinement, and micro-strain. The grain-refinement and induced micro-strain are calculated based on the...

Abstract null null A session-based software system provides various services to its end users through graphical user interfaces. A novice user of a service's user interface takes more think time—the average time to comprehend the content and its layout on the interface—in comparison to expert users. The think time gradually decreases as she repeatedly comprehends the same interface over time. This decrease in think time is the user learning phenomenon. Owing to this learning behavior, the propor...

Abstract null null The System Biology Markup Language (SBML) has been used to build numerous models of biological processes. Here we introduce a new method to translate SBML specifications of cellular models into formal specifications for analysis and simulation. To do so we define a generic biological model architecture that can be instantiated with different parameters for different types of cells and at different levels of detail using the information available in SBML models. We discuss said...

Abstract null null Flexible job shop scheduling problem (FJSSP) is a critical operational planning step in manufacturing that ensures on-time delivery of goods leading to customer satisfaction. The process of assigning jobs to machines has a larger solution space and consumes a huge amount of time and effort. This research focuses on solving FJSSP using the discrete event simulation (DES) model and integrates it with Composite Dispatching Rules (CDRs) and multi-criteria decision making (MCDMs) b...

Abstract null null Martensitic stainless steel is widely used where there is a need for strength, hardness, and corrosion resistance. But the machinability of this steel is difficult because of its poor thermal conductivity, as it leads to high tool wear. Application of coating on the cutting tool is one of the sustainable techniques utilized in improving the machinability of work material. But the problem in the application of the coated tool is the determination of different coating materials ...

Abstract null null In this paper, 1 null we describe LUNES-Blockchain, an agent-based simulator of blockchains that relies on Parallel and Distributed Simulation (PADS) techniques to obtain high scalability. The software is organized as a multi-level simulator that permits to simulate a virtual environment, made of many nodes running the protocol of a specific Distributed Ledger Technology (DLT), such as the Bitcoin or the Ethereum blockchains. This virtual environment is executed on top of a lo...

Abstract null null This paper presents a comparative assessment of two-dimensional convolutional neural networks (2DCNN) and boosting methods for regression-based textile whiteness estimation, applied to high resolution images of textiles of an industrial cotton textiles producer, labelled with whiteness values, thus enabling supervised learning. The images were taken under various lighting conditions. Concerning the machine learning methods, Random Forest and XGBoost were the selected and teste...

Abstract null null The Feed-Forward and Backpropagation Artificial Neural Networks (FFBP-ANN) are generally employed for cut surfaces quality characteristics predictions. However, the determination of the neurons on the hidden layer and the training parameters’ values are tasks requiring many trials according to the Full-Factorial Approach (FFA). Therefore, in this work, a methodology is presented for the optimization of an FFBP-NN and the application of the Taguchi Design of Experiments (TDE). ...
