Advanced-Collision-Map-Based On-line Collision and Deadloack Avoidance between Two Robot Manipulators with PTP Commands

AFAGHANI, Ahmad Yasser

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

Suppression of Υ (1S) at forward rapidity in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on the measurement of the inclusive Υ (1S) production in Pb–Pb collisions at √sNN = 2.76 TeV carried out at forward rapidity (2.5 < y < 4) and down to zero transverse momentum using its μ+μ− decay channel with the ALICE detector at the Large Hadron Collider. A strong suppression of the inclusive Υ(1S) yield is observed with respect to pp collisions scaled by the number of independent nucleon– nucleon collisions. The nuclear modification factor, for events in the 0–90% centrality range, amounts to 0.30 ± 0.05(stat) ± 0.04(syst). The observed Υ (1S) suppression tends to increase with t ...Daha fazlası

Multiplicity dependence of jet-like two-particle correlation structures in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Two-particle angular correlations between unidentified charged trigger and associated particles are measured by the ALICE detector in p–Pb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV. The transverse-momentum range 0.7 < pT,assoc < pT,trig < 5.0 GeV/c is examined, to include correlations induced by jets originating from low momentum-transfer scatterings (minijets). The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range |η| < 0.9. The near-side long-range pseudorapidity correlations observed in high-multiplicity p–Pb col ...Daha fazlası

Purpose: To examine functional mobility status on discharge day after total knee and hip replacement surgery in post-acute care hospital setting. Methods: Eighty patients following total knee and hip replacement surgery were assessed with the de Morton Mobility Index (DEMMI), the Timed-Up-and-Go (TUG) and Five Times Sit to Stand Test, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) measurements of mobility-related activity on discharge day. Demographic information comprised age, body mass index, gender, type of surgery,length of hospital stay. Since the normality of ...Daha fazlası

Multiparticle azimuthal correlations in p-Pb and Pb-Pb collisions at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

Measurements of multiparticle azimuthal correlations (cumulants) for charged particles in p-Pb at √sNN = 5.02 TeV and Pb-Pb at √sNN = 2.76 TeV collisions are presented. They help address the question of whether there is evidence for global, flowlike, azimuthal correlations in the p-Pb system. Comparisons are made to measurements from the larger Pb-Pb system, where such evidence is established. In particular, the second harmonic two-particle cumulants are found to decrease with multiplicity, characteristic of a dominance of few-particle correlations in p-Pb collisions. However, when a |η| gap i ...Daha fazlası

Suppression of ψ(2S) production in p-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The ALICE Collaboration has studied the inclusive production of the char- monium state ψ(2S) in proton-lead (p-Pb) collisions at the nucleon-nucleon centre of mass energy √sNN = 5.02 TeV at the CERN LHC. The measurement was performed at forward (2.03 < ycms < 3.53) and backward (−4.46 < ycms < −2.96) centre of mass rapidities, studying the decays into muon pairs. In this paper, we present the inclusive production cross sections σψ(2S), both integrated and as a function of the transverse momentum pT, for the two ycms domains. The results are compared to those obtained for the 1S vector state (J ...Daha fazlası

Azimuthal anisotropy of D-meson production in Pb-Pb collisions at √sN N = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of the prompt charmed mesons D0, D+, and D∗+ relative to the reaction plane was measured in Pb-Pbcollisionsatacenter-of-massenergypernucleon-nucleoncollisionof√sNN =2.76TeVwiththeALICE detector at the CERN Large Hadron Collider. D mesons were reconstructed via their hadronic decays at central rapidity in the transverse-momentum (pT ) interval 2–16 GeV/c. The azimuthal anisotropy is quantified in terms of the second coefficient v2 in a Fourier expansion of the D-meson azimuthal distribution and in terms of the nuclear modification factor RAA, measured in the direction of the reac ...Daha fazlası

Freeze-out radii extracted from three-pion cumulants in pp, p–Pb and Pb–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose–Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. In low-multiplicity collisions, unlike in high-multiplicity collisions, two-pion correlations are substantially altered by background correlations, e.g. mini-jets. Such correlations can be suppressed using three-pion cumulant correlations. We present the f ...Daha fazlası

A Novel Underlay Cognitive Radio Based on Direct Sequence Complementary Coded CDMA

KIZILIRMAK, Refik Çağlar

In this study, we propose a spectrum sharing scheme where secondary-users (SUs) can co-exist at the same frequency band with the primary-users simultaneously. Both primary (PN) and secondary networks (SN) are considered as CDMA based networks with the same set of orthogonal complementary codes. An orthogonal complementary code set possesses both ideal auto-correlation function (ACF) of any code and ideal cross-correlation function for any two codes in the same set. In the proposed scheme, a delay is applied to the transmission of the SN which exploits ideal ACF properties of complementary code ...Daha fazlası

A 3D face animation system for mobile devices

MENDİ, Engin

In this paper, we present a 3D face animation system rendered on mobile devices. The system automatically creates realistic facial animation from text input with emotion tags. First, an input string is converted into synthetic voice and phonetic information. Then, 3D head model performs facial movements synchronized to the speech. The proposed system offers an affordable quick solution for applications that require virtual actors speaking text in which human-machine interfaces on mobile devices can profit.

Event-by-event mean pT fluctuations in pp and Pb–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Event-by-event fluctuations of the mean trans- verse momentum of charged particles produced in pp colli- sions at √s = 0.9, 2.76 and 7 TeV, and Pb–Pb collisions at √sNN = 2.76 TeV are studied as a function of the charged- particle multiplicity using the ALICE detector at the LHC. Dynamical fluctuations indicative of correlated particle emis- sion are observed in all systems. The results in pp collisions show little dependence on collision energy. The Monte Carlo event generators PYTHIA and PHOJET are in qualitative agreement with the data. Peripheral Pb–Pb data exhibit a sim- ilar multiplicity ...Daha fazlası
