The pT-differential production cross sections of the prompt charmed mesons D0, Dþ, D þ, and Dþs and center-of-mass energy sNN 1⁄4 5.02 TeV with the ALICE detector at the LHC. The nuclear modification factor RpPb, quantifying the D-meson yield in p-Pb collisions relative to the yield in pp collisions scaled by the number of binary nucleon-nucleon collisions, is compatible within the 15%–20% uncertainties with unity in the transverse momentum interval 1 < pT < 24 GeV=c. No significant difference among the RpPb of the four D-meson species is observed. The results are described within uncertaintie ...Daha fazlası
The transverse momentum ( pT ) distribution of primary charged particles is measured at midrapidity in minimum-bias p–Pb collisions at √sNN = 5.02 TeV with the ALICE detector at the LHC in the range 0.15 < pT < 50 GeV/c. The spectra are compared to the expectation based on binary collision scaling of particle production in pp colli- sions, leading to a nuclear modification factor consistent with unity for pT larger than 2 GeV/c, with a weak indication of a Cronin-like enhancement for pT around 4 GeV/c. The mea- surement is compared to theoretical calculations and to data in Pb–Pb collisions at ...Daha fazlası
Linked data systems are still far from maturity. Hence, the basic principles are still open for discussion. In our study on building a novel linked data search engine, we have surveyed fundamental methods of internet search technologies in the context of linked data crawling, indexing, ranking, and monitoring. The scope of this ranking survey covers linked data related statistical ranking, database ranking, document level ranking, and Web ranking techniques. In order to classify the linked data ranking methods, we identified a number of categories. These categories are ontology ranking, RDF ra ...Daha fazlası
he inclusive J/ψ nuclear modification factor (RAA) in Pb–Pb collisions at √sNN = 2.76 TeV has been measured by ALICE as a function of centrality in the e+e− decay channel at mid-rapidity (|y| < 0.8) and as a function of centrality, transverse momentum and rapidity in the μ+μ− decay channel at forward-rapidity (2.5 < y < 4). The J/ψ yields measured in Pb–Pb are suppressed compared to those in pp collisions scaled by the number of binary collisions. The RAA integrated over a centrality range corresponding to 90% of the inelastic Pb–Pb cross section is 0.72 ± 0.06(stat.) ± 0.10(syst.) at mid-rapi ...Daha fazlası
Inclusive J/ψ production has been studied with the ALICE detector in p-Pb collisions at the nucleon–nucleon center of mass energy √sNN = 5.02TeV at the CERN LHC. The measurement is performed in the center of mass rapidity domains 2.03 < ycms < 3.53 and −4.46 < ycms < −2.96, down to zero transverse momentum, studying the μ+μ− decay mode. In this paper, the J/ψ production cross section and the nuclear modification factor RpPb for the rapidities under study are presented. While at forward rapidity, corresponding to the proton direction, a suppression of the J/ψ yield with respect to binary-scaled ...Daha fazlası
Model-driven approach for web application development is an important topic in software engineering. There are many existing tools to support model-driven engineering for web application development. However, most tools and techniques are complex and not very practical when it comes to real-life usage. Here we present a simple data model-driven approach for web application development that is based on RDF data model, the basic semantic Web data model, and its reasoning capabilities. We introduce a prototype implementation of the data model-driven Web application development framework that util ...Daha fazlası
Correlations induced by quantum statistics are sensitive to the spatiotemporal extent as well as dynamics of particle-emitting sources in heavy-ion collisions. In addition, such correlations can be used to search for the presence of a coherent component of pion production. Two- and three-pion correlations of same and mixed charge are measured at low relative momentum to estimate the coherent fraction of charged pions in Pb-Pb collisions at √sNN = 2.76 TeV at the CERN Large Hadron Collider with ALICE. The genuine three-pion quantum statistics correlation is found to be suppressed relative to th ...Daha fazlası
This research aims to build an on-line system for avoiding collisions and deadlocks between two robot manipulators which are controlled using point-to-point (PTP) commands. Both robots are sharing the same workspace and have no prior knowledge of the commands which will be sent after starting the system. We have proposed a collision map concept for detecting the collisions between the end-effectors of the robots [1]. In this work, an advanced collision map method has been created for detecting the collisions between the whole body of the robots and representing them as collision areas on the m ...Daha fazlası
In this study, we investigate a relay-assisted visible light communication (VLC) system where an intermediate light source cooperates with the main light source. Specifically, we consider two light sources in an office space; one is the information source employed on the ceiling and the other one is a task light mounted on a desk. Our system builds upon DC biased optical orthogonal frequency division multiplexing (DCO-OFDM). The task light performs amplify-and-forward relaying to assist the communication and operates in half-duplex mode. We investigate the error rate performance of the propose ...Daha fazlası

Injection is one of the methods to improve the engineering properties of bases. Various additions as well as cement are used for preparations of injection blends in order to lower costs and reach better results. For this purpose in the preparation of the injection blends, Bentonite (B), Fly Ash (FA) and Silica Fume (SF) were used at the ratios of 0-0.5-1-3%, 10-20-30-40% and 0-5-10-20%, respectively. Taguchi method was applied for the experiment and L16 Orthogonal (OA) with three factors and four levels were chosen. Granular bases having 0.70 relative density was settled into a cylindrical mol ...Daha fazlası
