    Title: High $p_{\rm T}$ spectra and anisotropy of light and heavy hadrons
    Author: Christiansen, Peter
    Subject: High Energy Physics - Phenomenology ; Nuclear Experiment
    Description: Data driven studies of heavy-ion results has played a big role in highlighting interesting features of these complex systems. In this proceeding, a simple QGP-brick interpretation of the $R_{\rm AA}$ and $v_{2}$ at high $p_{\rm T}$ ($p_{\rm T} \approx 10$ GeV/c) is presented. This interpretation draws attention to two fundamental questions: is there an effect of the asymmetric QGP expansion on the $v_{2}$ at high $p_{\rm T}$? is there an energy loss difference between quarks and gluons? Finally, it is discussed how these studies can be extended using Event-Shape Engineering and how they can be applied to compare the energy loss of light and heavy quarks. Comment: 5 pages, 2 figures, proceeding for Hard Probes 2016

    Title: What Quark-Gluon Plasma in small systems might tell us about nucleons
    Author: Christiansen, Peter
    Contributor: Christiansen, Peter (pacrepositoryorg)
    Subject: Gluons ; Quarks ; Quarks ; Collisions ; Hadrons ; Protons ; Quark-Gluon Plasma ; Nucleons
    Description: The origin of flow-like effects in small systems, such as those produced in ultra-relativistic proton-proton and proton-lead collisions, is still widely debated. In this paper the goal is to look at possible consequences if indeed a mini-Quark-Gluon Plasma is formed in these collisions. It is argued that this could indicate a duality between the QGP phase and the color fields in hadrons. A qualitative dense field picture is presented for this duality and discussed.

    Description: Data driven studies of heavy-ion results has played a big role in highlighting interesting features of these complex systems. In this proceeding, a simple QGP-brick interpretation of the \(R_{\rm AA}\) and \(v_{2}\) at high \(p_{\rm T}\) (\(p_{\rm T} \approx 10\) GeV/c) is presented. This interpretation draws attention to two fundamental questions: is there an effect of the asymmetric QGP expansion on the \(v_{2}\) at high \(p_{\rm T}\)? is there an energy loss difference between quarks and gluons? Finally, it is discussed how these studies can be extended using Event-Shape Engineering and how they can be applied to compare the energy loss of light and heavy quarks.

    Title: Claudian’s Art
    Author: Christiansen, Peter G; Christiansen, David
    Subject: History & Archaeology
    Description: Connu principalement aujourd’hui pour ses activités de propagandiste à la cour d’Honorius, Claudius Claudianus avait acquis une certaine renommée comme poète au début de sa carrière. Une lecture attentive de ses Carmina minora révèle sa connaissance intime de la poésie latine classique et son adhésion au républicanisme romain tout en suggérant des détails sur son évolution qui le conduisit de poète épique au panégyriste impérial. Il en résulte une appréciation plus profonde de sa carrière et de son héritage littéraire. Claudius Claudianus is commonly remembered for his activities as a propagandist in the court of Honorius, but earlier in his career he had established a reputation as a celebrated poet. A close reading of the Carmina Minora reveals his familiarity with classical Latin poetry and his identification with historic Roman Republicanism, while suggesting details about his transition from epic poetry to imperial panegyric. As a result, modern readers...

    Title: Towards a DSL for Perception-Based Safety Systems
    Author: Hansen, Mikkel; Christiansen, Peter; Schultz, Ulrik
    Contributor: Schultz, Ulrik (pacrepositoryorg)
    Subject: Programming Languages ; Domain Specific Languages ; Robotics ; Programming Languages
    Description: This paper is an extension to an early presented programming language, called a domain specific language. This paper extends the proposed concept with new sensors and behaviours to address real-life situations. The functionality was tested in lab experiments, and an extension to the earlier concepts is proposed.
