  Optimization of medical waste routing problem: The case of TRB1 region in Turkey

  Mete, Suleyman; Serin, Faruk

  A fundamental problem concerning medical waste disposal is the evaluation of the real and potential risks arising from waste with the focus on the risk of infection. Therefore, the optimization of medical waste routing from collection to disposal center can minimize the risk of infection. The routing of medical waste considers significant to determine potential routes and select the route with minimum distance. The management of the medical waste is important decision for environmental sustainability and includes the collection, transportation and disposal of these materials. In this paper, a geographic information system (GIS) solution approach is proposed to determine the best location of disposal center. Proposed approach is applied to medical waste transportation between 167 health institutions (collection centers) and predetermined 5 disposal centers through TRB1 region in Turkey, which consist of Malatya, Elazığ, Bingöl and Tunceli provinces. The results of case study are examined and suggestions for future research are provided.

  Heartbeat type classification with optimized feature vectors

  Yıldırım, Özal; Baloglu, Ulas Baran

  In this study, a feature vector optimization based method has been proposed for classification of the heartbeat types. Electrocardiogram (ECG) signals of five different heartbeat type were used for this aim. Firstly, wavelet transform (WT) method were applied on these ECG signals to generate all feature vectors. Optimizing these feature vectors is provided by performing particle swarm optimization (PSO), genetic search, best first, greedy stepwise and multi objective evoluationary algorithms on these vectors. These optimized feature vectors are later applied to the classifier inputs for performance evaluation. A comprehensive assessment was presented for the determination of optimized feature vectors for ECG signals and best-performing classifier for these optimized feature vectors was determined.

  A stochastic location and allocation model for critical items to response large-scale emergencies: A case of Turkey

  Celik, Erkan; Aydin, Nezir; Gumus, Alev Taskin

  This paper aims to decide on the number of facilities and their locations, procurement for pre and post-disaster, and allocation to mitigate the effects of large-scale emergencies. A two-stage stochastic mixed integer programming model is proposed that combines facility location-prepositioning, decisions on pre-stocking levels for emergency supplies, and allocation of located distribution centers (DCs) to affected locations and distribution of those supplies to several demand locations after large-scale emergencies with uncertainty in demand. Also,theuseofthemodelisdemonstratedthroughacasestudyfor prepositioning of supplies in probable large-scale emergencies in the eastern and southeastern Anatolian sides of Turkey. The results provide a framework for relief organizations to determine the location and number of DCs in different settings, by using the proposed model considering the main parameters, as; capacity of facilities, probability of being affected for each demand points, severity of events, maximum distance between a demand point and distribution center.

  New soliton properties to the ill-posed Boussinesq equation arising in nonlinear physical science

  Duran, Serbay; Sulaiman, Tukur Abdulkadir B; Aşkın, Muzaffer

  In manuscript, with the help of the Wolfram Mathematica 9, we employ themodified exponential function method in obtaining some new soliton solutions tothe ill-posed Boussinesq equation arising in nonlinear media. Results obtainedwith use of technique, and also, surfaces for soliton solutions are given. We alsoplot the 3D and 2D of each solution obtained in this study by using the sameprogram in the Wolfram Mathematica 9.

  New complex exact travelling wave solutions for the generalized- Zakharov equation with complex structures

  Bulut, Hasan; Baskonus, Haci Mehmet

  In this paper, we apply the sine-Gordon expansion method which is one of the powerful methods to the generalized-Zakharov equation with complex structure. This algorithm yields new complex hyperbolic function solutions to the generalized-Zakharov equation with complex structure. Wolfram Mathematica 9 has been used throughout the paper for plotting two- and three-dimensional surface of travelling wave solutions obtained.
