Detection of the Electronic Attributes of the Nanostructured Materials with Fuzzy Logic

ALLAHVERDİ, Novruz | GENCER, Muhammet Çağrı | VARDAR, Necati

This is a study, in which a trial was done to estimate the energy band gap (Eg) of single-walled carbon nanotubes (SWCNTs) by using a fuzzy logic algorithm that uses five inputs (strain value, fermi energy level, average energy, repulsive potential and electronic band structure energy).

Measuring K0S K± interactions using pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present the first measurements of femtoscopic correlations between the K0 and K± particles in pp √S collisions at s = 7 TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding solely via the a0(980) resonance. The extracted kaon source radius and correlation strength parameters for K0SK− are found to be equal within the experimental uncertainties to those for K0K+. Results of the present study are compared with those S√ from identical-kaon femtoscopic studies also performed with pp collisions at s = 7 TeV by ALICE a ...Daha fazlası

Gabion Structures and Design Criteria

URAY, Esra | TAN, Özcan | URAY, Kemal

Nowadays, railway is a kind of transportation due to cheap and safe. In railway construction route, many problems like supporting of lateral soil pressure, slope stability and rock fall have been experienced. Gabion basket and mesh wire have been used commonly for solution of these problems. The gabion basket is a rectangular basket which is obtained from hexagonal-double twisted galvanized mesh wire and is filled with small rock particles or stone. Gabion structures have been constructed with placing these baskets in a certain order. In railway construction, the gabion structures have been us ...Daha fazlası

Deep Learning for COPD Analysis Using Lung Sounds

ALLAHVERDİ, Novruz | ALTAN, Gökhan | KUTLU, Yakup

Deep Learning(DL) algotithms have become popular with the detailed analyzing capabilities with many hidden layers in recent years. The size of hidden layer in the classifier models is complately correlated with the analyzing capability of the proposed mode. Multiple hidden layers and neuron size in the hidden layers enhance the analyzing capability of the models,whereas increasing the training time.

J/ψ production as a function of charged-particle pseudorapidity density in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report measurements of the inclusive J/ψ yield and average transverse momentum as a function of charged-particle pseudorapidity density dNch/dη in p–Pb collisions at √sNN = 5.02 TeV with ALICE at the LHC. The observables are normalised to their corresponding averages in non-single diffractive events. An increase of the normalised J/ψ yield with normalised dNch/dη, measured at mid-rapidity, is observed at mid-rapidity and backward rapidity. At forward rapidity, a saturation of the relative yield is observed for high charged-particle multiplicities. The normalised average transverse momentum ...Daha fazlası

Methyl methacrylate in external fixation of supracondylar humerus fractures: An experimental study

GÜLEÇ, Ali | ACAR, Mehmet Ali | AYDIN, Bahattin Kerem | DEMİR, Teyfik | ÖZKAYA, Mustafa

Supracondylar humerus fractures are common fractures around the elbow. Open fractures, comminuted metaphyseal fractures and also fractures with bone loss may need to be treated with external fixators. The aim of this study is to compare two different external fixators, tubular external fixators and polymethyl methacrylate with K wires external fixators, with regard to stiffness and stability for metaphyseal-diaphyseal osteotomies of distal humerus close to the joint. Six matched pairs (24 specimens) of second-generation sawbone humerus were prepared in a standard fashion to create a metaphysea ...Daha fazlası

Flood Modeling of Samsun/Atakum Region by GIS Tools

BEDEN, Neslihan | DEMİR, Vahdettin | ÜLKE KESKİN, Aslı

Study area Samsun/Atakum province is almost under threat of flooding in each year. In this region, the main reason of devastating flood is the influence of the Degirmen stream especially during March, April, and July and due to seasonal rainfall, which eventually makes the district vulnerable to flooding. In addition, the human-based constructions and the collapse of water retaining structures are among the main causes of flooding. In this study flood risks of Samsun Degirmen stream determinate by MIKE 11 and GIS. Numerical model selection for studies provides advantages in developing and chan ...Daha fazlası

Transverse momentum spectra and nuclear modification factors of charged particles in Xe–Xe collisions at √sNN = 5.44 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Transverse momentum (pT) spectra of charged particles at mid-pseudorapidity in Xe–Xe collisions at √sNN = 5.44 TeV measured with the ALICE apparatus at the Large Hadron Collider are reported. The kinematic range 0.15 < pT < 50 GeV/c and |η| < 0.8 is covered. Results are presented in nine classes of collision centrality in the 0–80% range. For comparison, a pp reference at the collision energy of √s = 5.44 TeV is obtained by interpolating between existing pp measurements at √s = 5.02 and 7 TeV. The nuclear modification factors in central Xe–Xe collisions and Pb–Pb collisions at a similar center ...Daha fazlası

Analysis of Annual, Seasonal, and Monhtly Trends of Climatic Data: A Case Study of Samsun

ÜLKE KESKİN, Aslı | BEDEN, Neslihan | DEMİR, Vahdettin

Climate change impacts are perceived today as being very noticeable; determination of precipitation, wind, flow, evaporation and temperature trends has become essential for water resources and engineering projects in management and planning. Nowadays there is a lot of studies have been made in progress on global and regional climate changes in literature. In this study, monthly, annual and seasonal trends in average temperature, total precipitation, and average wind speed data calculated by Mann-Kendall, linear trend and Sen’s trend tests. The gauge station is located in Samsun, which is the l ...Daha fazlası

Unsupervised Change Detection in Landsat Images with Atmospheric Artifacts: A Fuzzy Multiobjective Approach

YAVARIABDI, Amir | KUSETOĞULLARI, Hüseyin

A new unsupervised approach based on a hybrid wavelet transform and Fuzzy Clustering Method (FCM) with Multiobjective PMakale Swarm Optimization (MO-PSO) is proposed to obtain a binary change mask in Landsat images acquired with different atmospheric conditions. The proposed method uses the following steps: preprocessing, classification of preprocessed image, and binary masks fusion. Firstly, a photometric invariant technique is used to transform the Landsat images from RGB to HSV colour space. A hybrid wavelet transform based on Stationary (SWT) and Discrete Wavelet (DWT) Transforms is applie ...Daha fazlası

Sliding Mode Control of a Two-link Robot Manipulator Using Adams & Matlab Software

İLGEN, Sinan | DURDU, Akif | GÜLBAHÇE, Erdi | ÇAKAN, Abdullah

This paper presents the design of a sliding mode controller (SMC) for trajectory tracking problem for a two-link planar robot manipulator. A virtual prototype of the manipulator has been built by using Adams software. Also, the controller works is achieved in Matlab/Simulink software. The system is simulated in both Matlab and Adams software together which is called co-simulation. The manipulator system has two inputs (torques of actuators) and four outputs (angle of 1st joint, angle of 2nd joint and x-y components of end effector position). The sliding mode controller (SMC) is designed with t ...Daha fazlası
