Fluidstructure interaction (FSI) problems play an important role in many technical applications, for instance, wind turbines, aircrafts, injection systems, or pumps. Thus, the optimization of such kind of problems is of high practical importance. Optimization algorithms aim to find the best values for a system's parameters under various conditions. In this paper an approach for multi-objective opt...Show More
Collaboration is complex. To solve a problem occurring in collaboration, using computers, we must first define and specify the problem. This paper presents a challenging problem in collaboration, called group role assignment with cooperation and conflict factors (GRACCFs). This problem's solution aims at creating a high-performance group by role assignment with consideration of cooperation and con...Show More

Two formulations of the role assignment problem within the framework of the role-based access control policy are considered. As part of the task, it is required to assign a set of roles to the user in such a way that his authority needs are met, while the damage to the information system would be minimal. In the first task, the damage arising due to the possible compromise of the roles of this use...Show More
Adaptive collaboration (AC) is essential for group performance optimization in collaborative systems. This paper begins by introducing AC within the context of solving a real-world problem. Next, AC problems are formalized based on the environment-class, agent, role, group, and object (E-CARGO) model. Three algorithms are proposed for solving AC problems. They are based on three different scenario...Show More
In many organizations, there are projects of the same kind continually being created to work on. When role-based access control (RABC) is applied to resources' access control in these organizations, a problem arises, that is, the coming projects make a series of similar roles that are with same functions be created continually, and this makes roles administration hard. The similar roles are differ...Show More
The problem-based learning model utilizes cooperative group work to approach ill-structured, real-world problems. Proponents of the problem-based learning model argue that by providing authentic, real-world problems in a peer-supported group setting, learners are better able to apply their knowledge after graduation. Studies have shown that problem-based learning affords students advantages such a...Show More
Traveling Salesman Problem (TSP), despite its simple appearance, is one of the classic and complex problems in Combinatorial Optimization and it is difficult to find an accurate answer for large samples. This problem is so important that many real-world problems can be turned into a TSP and solved. Optimization methods for solving difficult problems, such as TSP, mainly involve a large number of v...Show More
Role-based collaboration (RBC) theory is a promising paradigm for problem-solving in complex systems. Multigroup role assignment (MGRA) specifically tackles the task of assigning roles for multigroup collaboration. However, due to the constraint that an agent can only play a role in one group, the current MGRA models are incapable of handling when required agents outnumber the available supply. Gr...Show More
In this paper, we present a new multimodal optimization algorithm, role based particle swarm optimization (RPSO), for finding and maintaining multiple optima in objective function landscape. Instead of generating all trial vectors randomly, the swarm population is divided into three kinds of roles, each part of swarms generating offsprings with different strategy. A species conservation procedure ...Show More

Year: 2021 | Volume: 86, Issue: 1 | Journal Article |
Recently in Charalambopoulos et al. (2020), we presented a methodology aiming at reconstructing bounded total variation ($TV$) conductivities via a technique simulating the so-called half-quadratic minimization approach, encountered in Aubert & Kornprobst (2002, Mathematical Problems in Image Processing. New York, NY: Springer). The method belongs to a duality framework, in which the auxiliary fun...Show More

River Formation Dynamics (RFD) is an heuristic optimization algorithm based on copying how water forms rivers by eroding the ground and depositing sediments. After drops transform the landscape by increasing/decreasing the altitude of places, solutions are given in the form of paths of decreasing altitudes. Decreasing gradients are constructed, and these gradients are followed by subsequent drops ...Show More
Online learning played an increasingly important role in education. While the COVID-19 pandemic made institutions shift classroom learning to online learning. Online learning caused various problems that affect the physical and mental health problems of students. They needed to be confined indoors and sitting in front of electronic devices resulting in stress, depression, or fatigue. Certainly, CO...Show More
Computational thinking (CT) has received increasing attention from educational researchers as a higher-order thinking skill. CT is a key factor that influences the learning process and facilitates the acquisition of knowledge and the improvement of students’ academic performance. However, the mechanisms of how CT affects students’ academic performance have yet to be explored in depth. Based on thi...Show More

In this paper we consider the relation between beliefs and goals in agent theory. Beliefs play three roles in reasoning about goals: they play a role in the generation of unconditional desires from conditional ones, they play a role in adoption of desires as goals, and they play a role in the selection of plans to achieve goals. In this paper we consider the role of goals in reasoning about belief...Show More
