Investigation of Design Criteria for the Type of Gabion Walls

URAY, Esra | TAN, Özcan

In civil engineering, connecting two different levels each other to provide the essential safety is a common problem and in solving this problem retaining structures are widely used. In this study, the design criteria of gabion retaining wall which is a kind of retaining wall was investigated by using Taguchi Method. Parameters which affect the design of gabion retaining wall are height, length of base, wall angle and angle of internal friction and slope of backfill and 16 different Taguchi design tables were formed by these using parameters. These design tables were modelled by using computer ...Daha fazlası

Harmoni Arama Algoritması İle Betonarme Konsol Dayanma Duvarlarının Optimum Tasarımı

URAY, Esra | ÇARBAŞ, Serdar | ERKAN, İbrahim Hakkı | TAN, Özcan

Günümüzde, karşılaşılan bazı karmaşık mühendislik problemlerinin çözümünde matematik tabanlı deterministik yöntemler yetersiz kalabilmektedir. Bu tür durumlarda daha kısa sürede güvenilir sonuçlara ulaşmak için sezgisel optimizasyon yöntemleri kullanılmaktadır. Harmoni arama algoritması, son zamanlarda geliştirilen bir sezgisel optimizasyon yöntemidir. Bu algoritma, müzik icrası sırasında en iyi harmoniyi bulma prensibine dayanmaktadır. Harmoni arama algoritması, gradyan arama yerine rastgele aramayı kullanır. Yöntemde tasarım değişkenleri için herhangi bir başlangıç değerine ihtiyaç duyulmaz. ...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

Measurement of charged jet production cross sections and nuclear modification in p–Pb collisions at √ sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Charged jet production cross sections in p-Pb collisions at root s(NN) = 5.02 TeV measured with the ALICE detector at the LHC are presented. Using the anti-k(T) algorithm, jets have been reconstructed in the central rapidity region from charged particles with resolution parameters R = 0.2 and R = 0.4. The reconstructed jets have been corrected for detector effects and the underlying event background. To calculate the nuclear modification factor, R-pPb, of charged jets in p-Pb collisions, a pp reference was constructed by scaling previously measured charged jet spectra at root s = 7 TeV. In the ...Daha fazlası

Decode-and-forward relaying based on orthogonal complementary codes

KIZILIRMAK, Refik Çağlar

In this note, we propose a full-duplex decode-and-forward cooperative diversity scheme based on code division with orthogonal complementary codes. We consider a simple case in which a single user is assisted by a single relay to achieve cooperative diversity. When the cooperation is full-duplex, the operational delay of the relay makes the channel asynchronous and this may cause multiple-access interference (MAI) between the user and relay. The orthogonal complementary codes have perfect autocorrelation and cross-correlation properties that provide MAI-free operation in asynchronous channels. ...Daha fazlası
