Abstract:

Managing complex Cyber-Physical Energy Systems (CPES) requires solving various optimization problems with multiple objectives and constraints. As distributed control architectures are becoming more popular in CPES for certain tasks due to their flexibility, robustness, and privacy protection, multi-objective optimization must also be distributed. For this purpose, we present MO-COHDA, a fully distributed, agent-based algorithm, for solving multi-objective optimization problems of CPES. MO-COHDA allows an easy and flexible adaptation to different use cases and integration of custom functionalit

We present physical/mathematical models base on partial differential equations (PDEs) and efficient numerical simulation schemes based on the Finite Element (FE) method for multi-field problems, where the acoustic field is the field of main interest. Acoustics, the theory of sound, is an emerging scientific field including disciplines from physics over engineering to medical science. We concentrate on the following three topics: vibro-acoustics, aero-acoustics and high intensity focused ultrasound. For each topic, we discuss the physical/mathematical modeling, efficient numerical schemes and p

Abstract:

Artificial physical optimizer (APO), as a new heuristic stochastic algorithm, is difficult to balance convergence and diversity when dealing with complex multi-objective problems.

A hybrid strategy guided multi-objective artificial physical optimizer algorithm (HSGMOAPO) is proposed.

Illustrative examples are provided to demonstrate the efficiency and simplicity of the proposed method in solving this type of multi- point boundary value problems.

Many implicit representations like local extreme machine or Siren are proposed but they are still too compact to suffer from limited accuracy in handling local details and a long time of convergence.

In addition, this algorithm is a multi-dimensional advection algorithm, and it can decrease the error encountered in the direction-split advection algorithm.

Our objective is to identify links between physical health and community participation among individuals with schizophrenia or a psychosis mental illness. Semi-structured qualitative and quantitative interviews and community tours were conducted over 10 months ( N = 30). Interviews were transcribed and analyzed using a grounded theory coding strategy. Physical health played an important role in community participation both as a cause and consequence. Key processes included mobility issues impeding physical community involvement; a multi-directional relationship between social relationships, co

Abstract:

The modelling of an efficient CPS is emphasis with the origin of novel functionality over the applications with various design elements. These elements are generally uncertain where these elements include sensors, scheduling, resources, and optimization process. Here, an extensive analysis is carried out with the modelling of CPS element-driven problem formulation. The formulated problems are resolved using a multi-objective evolutionary (MOEA) algorithm to show the intelligence of the optimization approach in the CPS design level. The proposed MOEA shows the viability of the CPS element-drive

Abstract:

In today's global climate crisis, energy-efficient building design is crucial for achieving energy efficiency, environmental sustainability, and resident well-being. However, traditional architectural design is difficult to solve complex multi-objective and multivariate optimization problems. To overcome these challenges, this study proposes a solution: a strategy that combines decomposed multi-objective and agent assisted modeling. The proposed method decomposes complex architectural design problems into multiple manageable sub problems, with each sub problem optimized for a specific design o

Abstract:

Hip fracture in the elderly is a major health problem. Multi-professional rehabilitation approaches were recommended; however, there were various multi-professional rehabilitation models; therefore, identifying the multi-professional rehabilitation model, especially for older persons after hip fracture surgery, is needed. The aim of this review study is to identify a multi-professional rehabilitation model among the elderly with hip fracture surgery. A literature search for relevant articles in PubMed, Scopus, Embase, and CINAHL was used. Studies that met the following criteria were included:

Abstract:

In this paper, a grid-free deep learning method based on a physics-informed neural network is proposed for solving coupled Stokes–Darcy equations with Bever–Joseph–Saffman interface conditions. This method has the advantage of avoiding grid generation and can greatly reduce the amount of computation when solving complex problems. Although original physical neural network algorithms have been used to solve many differential equations, we find that the direct use of physical neural networks to solve coupled Stokes–Darcy equations does not provide accurate solutions in some cases, such as rigid t

Abstract:

Optimal layout problems consist in positioning a given number of components in order to minimize an objective function while satisfying geometrical or functional constraints. Such kinds of problems appear in the design process of aerospace systems such as satellite or spacecraft design. These problems are NP-hard, highly constrained and dimensional. This paper describes a two-stage algorithm combining a genetic algorithm and a quasi-physical approach based on a virtual-force system in order to solve multi-container optimal layout problems such as satellite modules.

Abstract:

In a recent paper, Cohl and Costas-Santos derived a number of interesting multi-derivative and multi-integral relations for the associated Legendre and Ferrers functions in which the orders of those functions are changed in integral steps. These are of potential use in a number of physical problems. We show here how their results can be derived simply from more general relations involving non-integer changes in the order obtained using the fractional group operator methods developed earlier for SO(2,1), E(2,1) and its conformal extension, and SO(3). We also present general integral relations f

Abstract:

In this paper, we propose a numerical scheme to solve multi-dimensional Black-Scholes equation using the global radial basis functions-based dierential quadrature (RBFs-DQ) method. Before applying the method, it is needed to remove mixed derivatives from the Black-Scholes equation by making an appropriate change of variables . Then, any spatial derivatives are approximated by a linear weighted sum of all the function values in the whole physical domain. In the RBFs-DQ method the weighting coecients are computed by RBFs. The method is very easy to implement and the non-singularity is ensured. T

Abstract:

The analysis of complex systems tends to be approached through a separation and a simplification of the main macro phenomena and, thus, addressed through dedicated techniques, tools, and algorithms. A smart and interesting possibility, instead, is represented by the so-called model-based design analysis, which allows one to interface phenomena coming from interactions of different physical natures. This paper aims to propose a multi-physics Matlab/Simulink®-based architecture that allows one to integrate general and strongly non-linear coupling phenomena, taking efforts from two novel implemen

Abstract:

A multidimensional analysis code for reactive shocks (MARS), which is developed to solve various problems in the physical hazard analysis of high energetic materials, has been applied to such complex problems as multi-material problem and sympathetic problem because it can employ various types of equations of state and a materials database. However, it was difficult to meet a growing demand for large-scale analysis and fluid-structure interaction (FSI) analysis. To address these issues, this study reports a parallelization of the code and an implementation of the functional capability of FSI a
