The Effect of Sr Modification and Holding Time on Si Morphology and Mechanical Properties of ETIAL 195 Alloy

ULUDAĞ, Muhammet | GEMİ, Lokman | ERYILMAZ, Muhammed Raşit | DIŞPINAR, Derya

Hypereutectic Al-Si alloys are typically used in applications where wear resistance is required. The primary factor that determines the wear properties is the morphology of Si in these types of alloys. Pouring temperature is one of the ways to control Si size and shape. On the other hand, bifilm defects that may be present in the liquid can significantly alter the morphology of Si acting as a heterogeneous nucleant. Therefore in this work, castings were made at 800 degrees C with varying holding time and the effects of bifilm on the Si morphology was studied. Bifilm content was measured by Red ...Daha fazlası

Forward-backward multiplicity correlations in pp collisions at √s = 0.9, 2.76 and 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The strength of forward-backward (FB) multiplicity correlations is measured √ s = 0.9, 2.76 and 7TeV. The measurement is performed in the central pseudorapidity region (|η| < 0.8) for the transverse momentum pT > 0.3GeV/c. Two separate pseudorapidity windows of width (δη) ranging from 0.2 to 0.8 are chosen symmetrically around η = 0. The multiplicity correlation strength (bcorr) is studied as a function of the pseudorapidity gap (ηgap) between the two windows as well as the width of these windows. The correlation strength is found to decrease with increasing ηgap and shows a non-linear increas ...Daha fazlası

Centrality dependence of inclusive J/ψ production in p-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present a measurement of inclusive J/ψ production in p-Pb collisions at √sNN = 5.02TeV as a function of the centrality of the collision, as estimated from the energy deposited in the Zero Degree Calorimeters. The measurement is performed with the ALICE detector down to zero transverse momentum, pT, in the backward (−4.46 < ycms < −2.96) and forward (2.03 < ycms < 3.53) rapidity intervals in the dimuon decay channel and in the mid-rapidity region (−1.37 < ycms < 0.43) in the dielectron decay channel. The backward and forward rapidity intervals correspond to the Pb-going and p-going direction ...Daha fazlası

Measurement of electrons from semileptonic heavy-flavor hadron decays in p p collisions at √ s = 2.76     TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The pT-differential production cross section of electrons from semileptonic decays of heavy-flavor hadrons has been measured at midrapidity in proton-proton collisions at s 1⁄4 2.76 TeV in the transverse momentum range 0.5 < pT < 12 GeV=c with the ALICE detector at the LHC. The analysis was performed using minimum bias events and events triggered by the electromagnetic calorimeter. Predictions from perturbative QCD calculations agree with the data within the theoretical and experimental uncertainties.

Measurement of pion, kaon and proton production in proton–proton collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The measurement of primary π ± , K ± , p and p production at mid-rapidity (|y| < 0.5) in proton–proton col- lisions at √s = 7 TeV performed with a large ion collider experiment at the large hadron collider (LHC) is reported. Particle identification is performed using the specific ioni- sation energy-loss and time-of-flight information, the ring- imaging Cherenkov technique and the kink-topology identifi- cation of weak decays of charged kaons. Transverse momen- tum spectra are measured from 0.1 up to 3 GeV/c for pions, from 0.2 up to 6 GeV/c for kaons and from 0.3 up to 6 GeV/c for protons. Th ...Daha fazlası

Measurement of jet quenching with semi-inclusive hadron-jet distributions in central Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report the measurement of a new observable of jet quenching in central Pb-Pb collisions at √sNN = 2.76 TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high-pT) charged hadron trigger. Jets are measured using collinear-safe jet reconstruction with infrared cutoff for jet constituents of 0.15 GeV, for jet resolution parameters R = 0.2, 0.4 and 0.5. Underlying event background is corrected at the event-ensemble level, without imposing bias on the jet population. Recoil jet spectra are reported in the range 20 < pch < 100 GeV.

Unsupervised Satellite Change Detection Using Particle Swarm Optimisation in Spherical Coordinates

UŞAKLI, Ali Bülent | YAVARIABDI, Amir | KUSETOĞULLARI, Hüseyin

This paper proposes a new unsupervised satellite change de- tection method, which is invariant to shadow and shading e ects. To achieve this, rstly, the RGB satellite images are transformed into spher- ical colour space to remove illumination artifacts. Then, a new unsuper- vised change detection is used. The resultant optimal binary change mask is obtained by minimisation a mean square error based cost function us- ing Binary Particle Swarm Optimisation (BPSO). The proposed method is compared with three other satellite change detection methods and the results demonstrate that our method provi ...Daha fazlası

Multiplicity dependence of charged pion, kaon, and (anti)proton production at large transverse momentum in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of charged pions, kaons and (anti)protons has been measured at mid-rapidity (−0.5 < y < 0) in p–Pb collisions at √sNN = 5.02 TeV using the ALICE detector at the LHC. Exploiting particle identification capabilities at high transverse momentum (pT), the previously published pT spectra have been extended to include measurements up to 20 GeV/c for seven event multiplicity classes. The pT spectra for pp collisions at √s = 7 TeV, needed to interpolate a pp reference spectrum, have also been extended up to 20 GeV/c to measure the nuclear modification factor (RpPb) in non-single diffrac ...Daha fazlası

The effect of simulator-education on students receiving education at the department of elderly care

SAYGILI, Ülkü | ÖZKALP, Birol

Usage and development of new learning tools increased along with the developing technology in health education. The changing expectations in the health services drew attention to clinical skill trainings. Patient safety, which is among the rising values, the struggle to increase the patient rights and student competency, enabled the simulation usage getting more and more widespread in the health education. These developments rising from the technology and education paved the way for the applications and tools of simulation, which is used widespread in enhancing the technical and non-technical ...Daha fazlası

The effectiveness of similitor usage in the paramedic education

ÖZKALP, Birol | SAYGILI, Ülkü

Turkey, the educational simulation has an important place in terms of this changing sense in medical education. The universities, which review the training they provide, involve the simulation in their curriculum in order to enable the students-to-graduate to acquire the need of convenient knowledge and some skills during the faculty education. The team that is employed in 112 emergency health services primarily aims to perform interventions for saving the human life in cases of any danger, try to prevent the possible secondary damages while performing these interventions and thus, enable the ...Daha fazlası
