Football transformation into an industry with extraordinary financial flow has made this popular sport an attractive field for sports analysts. The development of the computer science and data science has led to the emergence of a concept called football match analysis. The goalkeepers, as a unique member of football teams and regrading their unique features and characteristics, play a crucial role in the outcome of competitions and the success of the teams. Therefore, analysis of various aspects of their performance is one of the essential issues in the application of data science in football. In this research, three separate parts have been studied. In the first part, by using pre-match... 

The global rise in the elderly population, coupled with shortages in medical equipment and healthcare professionals, along with the profound impact of epidemic outbreaks like COVID-19, has underscored the critical significance of home healthcare on a global scale. Currently in Iran, some hospitals and private companies provide home healthcare services to patients. This research focuses on optimizing the scheduling and routing of nurses providing home care services to patients. In the face of daily planning challenges, which include both anticipated and uncertain emergency demands, we propose a method to efficiently allocate nursing resources. To address the unpredictability of emergency... 

Efficient utilization of runways, as major bottlenecks at airports, not only minimizes flight delays but also plays a vital role in reducing fuel emissions and mitigating environmental impacts. Aircraft scheduling problem studied in this paper seeks to improve this efficiency through optimally scheduling departure/arrival aircraft on multiple runways. The primary innovation of this study lies in accounting for aircraft taxi times between runways and gates, as well as the landing delay patterns, which have not been simultaneously addressed in the literature. To solve the problem, an enhanced branch-and-price method has been developed, improving upon existing approaches in the literature. It... 

The material handling cost is a significant portion of the operational costs in a production system. Designing an efficient material transport network helps reduce these costs. In most unequal-area facility layout models, the total loaded trip distances are minimized, and the empty flows are overlooked. In these models, it is assumed that the transportation of load is possible through bidirectional rectilinear paths connecting pairs of departments, and the optimal location of departments is determined based on the rectilinear centroid-to-centroid distances. These assumptions lead to a complex network with a large number of edges, which is impractical to implement in reality. In this study, a... 

Efficient location of health centers is an essential decesion in healthcare strategic planning. Nowadays constructing multi-service health centers is highly paid attention because of multiple nature of most diseases. Concentrating patients' medical services in one center prevents them from traveling to different parts of cities, especially in mega cities. In this research we have developed a mathematical model for the location of multi-service health centers assuming probabilistic demand and service time. Medical services are divided in three groups: normal, emergency and preventive. Since patients may be referred to another service after recieving a service by doctors' order, health system... 

In this thesis, a decomposition approach is developed to solve Set Covering Problems (SCPs) through exploiting special structures of their coefficient matrices. The coefficient matrix of an SCP is so large in practical problems, but due to its low density, most of its entries are zero. Based on this observation, some methods can be developed to aggregate the 1's of the coefficient matrix in order to create special structures involving smaller dense subproblems. In this theisis, four structures called "block-angular", "semi-block angular", "partitioned" and "nested block-angular" structures are proposed and examined. For this purpose, First, some heuristic methods based on constraint... 

Nowadays, advanced and inexpensive pre-clinical methods for investigating the effects of anti-cancer drugs are expanding. One of the latest three-dimensional laboratory modeling for evaluating the effects of drugs is the use of tumor-on-chip technology, which actually models the physiological system of the body through three-dimensional scaffolds, multicellular cultures, and shaped vascular systems. In this study, three-dimensional culture of cancer cells was performed in the form of spheroids. A chip of U-shaped microstructures with and without gaps was used to trap cells and form cancer spheroids. We simulated the simultaneous effect of drug and oxygen concentration distribution inside the... 

Modeling and performance evaluation of the real time distributed systems is a significant problem. Stochastic activity network is one of the high level models used for this purpose. This network is an extension of generalized stochastic Petri net which is more powerful and flexible than other Petri net extensions. Checking the satisfiability of properties such as performance, dependability and user's expected properties is considerable in these models. Thus, using the approaches and generating modeling and model checking tools with the mentioned purpose is attractive. A model checker automatically checks the correctness of the system behaviors as properties against the model by getting the... 

This study has focused on the important problem of landing on a planet as an important current and future space mission. In this regard, dynamics modeling and integrated state estimation and control problems have been investigated in different views. To this aim, first a novel concurrent representation for translational and rotational kinematics has been developed based on the extension of modified Rodrigues parameters to dual space. This parameter set, called dual modified Rodrigues parameters (DMRP), is then utilized to establish an integrated roto-translational dynamic. The proposed DMRP-based kinematics and dynamics have been verified via comparison to traditional methods of... 

Prevalent deployment of Distributed Energy Resources(DERs) in the demand side of electrical energy grids has several advantages such as greenhouse gases emission reduction, mitigation of power losses in the distribution grids and abatement of the dependency on the wholesale generation companies. At the same time, it paves the way for the advent of local interactive energy trading frameworks. In the following thesis, a distributed data-driven algorithm is developed for market-clearing in a community-based local energy market. The social welfare maximization is considered as the objective of the energy trading. The production and demand of electricity are the decision variables of sellers and... 

Understanding biological systems requires extensive knowledge of individual parameters, and to study the processes of cell differentiation and cell behavior, a suitable environment must be created with the physiological conditions of the human body. For this purpose, with the knowledge of microfluidics, a microenvironment can be provided to study the behavior of cells on a small scale. The use of bone tissue model microfluidic chips is an alternative and new method in which it is possible to study the behavior of cells to differentiate into bone and to examine the toxicity of drugs, which in itself can help in the effective and successful treatment of these cases show. Therefore, in this... 

The main topic of this research is the navigation and control of a free-flying satellite with a robot manipulator while transferring and placing cargo on a space station. After connecting the cargo module, astronauts and robots need to deliver the available loads to the desired modules in a space station. Capturing an object or cargo is a critical issue studied extensively so far. However, delivery and placing of the cargo at the target point have not been investigated yet, to the best of the author’s knowledge; hence, this is a primary motivation for conducting the proposed research. After capturing the payload, the position and attitude of the manipulator with respect to the station’s... 

Cardiovascular disease (CVD) currently remains a considerable challenge for clinical treatments. CVDs account for N17.5 million deaths per year and will predictably increase to 23.6 million by 2030. The main purpose is to create human model systems to study the effect of disease mutations or drug treatment on the heart. In addition, engineered cardiac tissues are considered promising candidates to be transplanted to improve the function of diseased hearts. For engineered active tissues/organs, 3D bioprinting can fabricate complex tissue architecture with a spatiotemporal distribution of bioactive substances (cells, growth factors, and others) to better guide tissue regeneration. However,...
