Type-2 Fuzzy Rule-Based Expert System for Diagnosis of Spinal Cord Disorders
(Sharif University of Technology, 2019-01)The majority of people have experienced pain in their low back or neck in their lives. In this paper, a type-2 fuzzy rule-based expert system is presented for diagnosing the spinal cord disorders. The interval type-2 fuzzy ... -
A Comparison of Different Multi-Criteria Analyses for Electric Vehicle Charging Station Deployment
(RGN Publications, 2019)Scarcity in near future, and the price fluctuation of fossil fuels lead to many industries change their products that use these resources into more eco-friendly versions. One of the most recent and noticeable example of ... -
Deterministic stability and random behavior of a Hepatitis C model
(Public Library Science, 2017-07)The deterministic stability of a model of Hepatitis C which includes a term defining the effect of immune system is studied on both local and global scales. Random effect is added to the model to investigate the random ... -
Sistem Geliştirme Projelerinde Kullanılan Olgunluk Değerlendirme Araçları Üzerine Bir Literatür Araştırması
(Millî Savunma Üniversitesi Alparslan Savunma Bilimleri Enstitüsü, 2014)The system development projects in the defense industry differ from the ones in other sectors with their big budgets, complexity, and provision of important capability. The organizations taking part in the acquisition ... -
Radiation Dose Reduction in Thorax CT
(Çukurova Üniversitesi, 2014)Computerized Tomography is a method of working with X-rays and is increasing in application day by day. Scientists continue to conduct studies by reducing the dose of X-ray that patients are exposed to in order to reduce ... -
The location-allocation problem of drone base stations
(Elsevier Ltd, 2019)In this study, we consider the 3D location problem of multiple Drone Base Stations (DBSs) together with the allocation of the resources to serve the users in a wireless communication network. The problem is formulated as ... -
An Adaptive Tabu Search Algorithm for Market Clearing Problem in Turkish Day-Ahead Market
(IEEE Computer Society, 2018)In this study, we focus on the market clearing problem of Turkish day-ahead electricity market. We propose a mathematical model by extending the variety of bid types for different price regions. The commercial solvers may ... -
Inventory model of type (s, S) under heavy tailed demand with infinite variance
(Brazilian Statistical Association, 2019)In this study, a stochastic process X(t), which describes an inventory model of type (s, S) is considered in the presence of heavy tailed demands with infinite variance. The aim of this study is observing the impact of ... -
A fix-and-optimize heuristic for the integrated fleet sizing and replenishment planning problem with predetermined delivery frequencies
(Elsevier Ltd, 2019)In this study, we tackle an integrated fleet sizing and replenishment planning problem in a vendor managed inventory system. There is a set of customers whose inventory must be replenished using a given set of predetermined ... -
Thorax CT Dose Reduction Based on Patient Features: Effect of Patient Characteristics on Image Quality and Effective Dose
(Lippincott Williams and Wilkins, 2019)Computed tomography (CT) radiation dose reduction is vital without compromising image quality. The aim was to determine the effects of patient characteristics on the received radiation dose and image quality in ... -
Statistical distributions and reliability functions with type-2 fuzzy parameters
(Polish Academy of Sciences Branch Lublin, 2019)Type-2 fuzzy sets were initially given by Zadeh as an extension of type-1 fuzzy sets. There is a gnawing interest in type-2 fuzzy set and its memberships (named secondary memberships) to handle the uncertainty in type-1 ... -
Limit theorem for a semi - Markovian stochastic model of type (s,S)
(Hacettepe University, 2019)In this study, a semi-Markovian inventory model of type (s,S) is considered and the model is expressed by means of renewal-reward process (X(t)) with an asymmetric triangular distributed interference of chance and delay. ... -
An integrated production scheduling and workforce capacity planning model for the maintenance and repair operations in airline industry
(Elsevier Ltd, 2019)Maintenance, repair, and overhaul (MRO) activities for the airline sector are generally subject to some regulations to ensure the safety and the continuity of flights. The critical equipment on aircraft must go through MRO ... -
Optimization of the regional allocation of wind power capacity
With the growing impact of global warming and depletion of fossil fuels, the necessity of renewable energy resources is becoming more and more obvious. However, investing in intermittent renewable resources, such as wind ... -
Cyclic scheduling of parts and robot moves in m-machine robotic cells
(Elsevier Ltd, 2018)We consider a flow shop type manufacturing cell consisting of m machines and a material handling robot producing multiple parts. The robot transfers the parts between the machines and loads/unloads the machines. We consider ... -
Approximation formulas for the moments of the boundary functional of a Gaussian random walk with positive drift by using Siegmund's formula
(Taylor and Francis Inc., 2019)In this study, a boundary functional () are mathematically constructed for a Gaussian random walk (GRW) with positive drift beta and first four moments of the functional are expressed in terms of ladder variables based on ... -
Improving post-disaster road network accessibility by strengthening links against failures
(Elsevier B.V., 2018)We study a network improvement problem to increase the resilience of a transportation network against disasters. This involves optimizing pre-disaster investment decisions to strengthen the links of the network structurally. ... -
Energy conscious scheduling of a material handling robot in a manufacturing cell
(Elsevier Ltd, 2019)In cyclic scheduling of material handling robots in manufacturing cells, a common approach is to minimize the cycle time objective, which is a measure of the throughput of the cell. In a typical robot move cycle, robot ...
