Development of a database and decision support system for performance evaluation of soccer players

In this study, we investigate the general parameters to evaluate the performance of soccer players and develop a database for performance evaluation of soccer players and a relevant decision support system (DSS) to help people such as technical director. In the proposed DSS, the data is collected by Data Collectors by using a proposed database. It helps the technical director to realize the performances of soccer players quickly with real-time during games

Improving Outcomes for Solid-Organ Transplant Recipients At Risk from Cytomegalovirus Infection: Late-Onset Disease and Indirect Consequences

Cytomegalovirus (CMV) is one of the most important pathogens following solid-organ transplantation, and effective prevention of CMV infection is a priority. The long-term control of CMV infection is dependent, in part, on the development of CMV-specific T cells, and controversy exists regarding whether CMV prophylaxis may prevent this. Although preemptive therapy is beneficial for the prevention of CMV disease, monitoring of viral levels in the blood does not always reflect what is occurring in tissues. Persistent low-level CMV infection has been associated with indirect consequences, such as transplant-associated vasculopathy, posttransplantation diabetes, an increased risk of opportunistic infection, and graft rejection. The issues surrounding preventive strategies for CMV disease following solid-organ transplantation are reviewed. We argue that prophylaxis is more effective than preemptive therapy; extending the duration of prophylaxis to the period of less intense immunosuppression could protect patients from late-onset disease, as well as from the indirect effects of CMV infectio

Differential-algebraic equations in primal dual interior point optimization methods: A new approach to the parameterization of the central trajectory.

Interior Point Methods (IPMs) are iterative algorithms for mathematical optimization problems that can be interpreted as path-following procedures. Given a starting solution, the iterative scheme generates a sequence of points that converge to the optimal solution of the problem. The points specified by the iterative scheme lie on the central trajectory. The central trajectory is a smooth analytical curve in the interior of the feasible region of the problem. It starts from an interior point and ends at the optimal solution of the problem. Primal dual IPMs generate points that lie in the neighborhood of the central trajectory. The key ingredient of primal dual IPMs is the parameterization of the central trajectory. The duality gap depends linearly on the barrier parameter for the points in the central trajectory. In this research, a new approach to the parameterization of the central trajectory for primal dual IPMs is proposed. A continuous dynamical system that describes the rate of the change of the barrier parameter at the central trajectory is considered. Instead of parameterizing the central trajectory by the barrier parameter, it is parameterized by the time by describing a continuous dynamical system. Specifically, a new update rule based on the solution of an ordinary differential equation (ODE) for the barrier parameter of the primal dual IPMs is presented. The resulting ordinary differential equation combined with the first order Karush-Kuhn-Tucker conditions, which are algebraic equations, are called differential algebraic equations (DAEs). By solving DAEs, we follow approximately the central trajectory of the primal dual IPMs. By doing so, we find an optimal solution to the given problem.The proposed parameterization of the central trajectory for primal dual IPMs is investigated both for linear and convex quadratic optimization problems and primal dual IPMs are modified by using new parameterization. In addition, convergence, implementation, computational complexity and stability issues of the proposed parameterization of the central trajectory are also investigated. Some computational results for the proposed parameterization of the central trajectory for linear and convex quadratic optimization problems and applications to support vector machines (SVMs) for the classification problem are presented

Integration of Waste Reduction and Battery Production: Method Development and Application This study presents an environmentally integrated manufacturing system analysis for companies looking for the benefits of environmental management in achieving high efficiency levels. The roadmap for such a management system is established and it is shown that the decision making should consider producing more using less and nonhazardous. This approach recognizes the already existing activities while investigating alternative waste management solutions. The methodology consists of data collection, operational analyses of the processes, identification of wastes and evaluation of waste reduction alternatives proposed both technically and economically. The proposed methodology is examined in a car battery manufacturing company and results are reported to the decision makers
