Low-momentum pion enhancement from schematic hadronization of a gluon-saturated initial state

We study the particle production in the early stage of the ultrarelativistic heavy-ion collisions. To this end the Boltzmann kinetic equations for gluons and pions with elastic rescattering are considered together with a simple model for the parton-hadron conversion process (hadronisation). It is shown that the overpopulation of the gluon phase space in the initial state leads to an intermediate stage of Bose enhancement in the low-momentum gluon sector which due to the gluon-pion conversion process is then reflected in the final distribution function of pions. This pattern is very similar to the experimental finding of a low-momentum pion enhancement in the ALICE experiment at CERN LHC. Relations to the thermal statistical model of hadron production and the phenomenon of thermal and chemical freeze-out are discussed in this context

Implementation of Cluster expansion for hot QCD matter

We present a cluster expansion EoS model for strongly-interacting matter based on the generalized Beth-Uhlenbeck formalism to describe hadrons as bound clusters of quarks. This formalism can describe both confined and deconfined phases. Our emphasis is on the region of vanishing baryon densities, where numerical solutions available from Lattice QCD predict a smooth crossover transition from hadron to quark matter. Medium effects are taken into account as self energies, which are motivated from both perturbative QCD calculations and phenomenological models. Parameters are tuned to Lattice QCD data and result in a good agreement of the thermodynamics

A New Strategic Marketing Plan for a Hotel

The aim of the bachelor’s thesis was to analyse the current situation in the small seacoast Italian hotel “Acquasanta” and to create a new strategic marketing plan which is able to solve current problems, fill out gaps and lead to more successful competitive business. Having had a varied experience of working in the hotel field, the newly devised marketing plan is based on personal experiences, theoretical framework and research results. The theoretical framework of the thesis contains information relating to marketing and marketing analyses in general and specifically in the hospitality industry. Especially experiences of working at the Hotel “Acquasanta” during the summer season 2013 have been taken into consideration. The current marketing situation was analyzed precisely. SWOT and PESTEL analyses were undertaken as well as target group and competitor analyses. The hotel was evaluated by taking two internal categories such as strengths and weaknesses and relating them against two external categories - opportunities and threats. To get a multifaceted view of the current situation, a customer satisfaction questionnaire was devised and circulated among hotel guests. The results of the questionnaire research were analysed by using a software program and the data were graphically formulated and generated. In addition to these measures, the hotel management interview was conducted to help further to clarify any vagueness or unique issues. Based on this marketing research a new marketing strategy was developed. Both marketing and additional communication strategy mixes were updated taking into consideration known existing and subsequent shortcomings. Focus was not paid on the budgeting of the marketing plan at the request of hotel management during this process. Seemingly the hotel management envisaged that the creative proposals would result in a fresh thinking and innovative marketing plan. The resulting marketing proposals are scheduled for implementation during the next touristic season 2014. Implementation of the new strategy is a mix of dynamic and long term processes. During the implementation of the roll out process it will be very important to keep an eye on any changing external and specific market factors such as economic trend shifting, fashion shifts in tourism generally and regionally and even global and regional political events

Anisotropic flow fluctuations in Pb+Pb collisions at LHC

Fluctuations of anisotropic flow in lead-lead collisions at LHC energies arising in HYDJET++model are studied. It is shown that intrinsic fluctuations of the flow which appear mainly because of the fluctuations of particle multiplicity, momenta and coordinates are insufficient to match the measured experimental data, provided the eccentricity of the freeze-out hypersurface is fixed at any given impact parameter b. However, when the variations of the eccentricity in HYDJET++ are taken into account, the agreement between the model results and the data is drastically improved. Both model calculations and the data are filtered through the unfolding procedure. This procedure eliminates the non-flow fluctuations to a higher degree, thus indicating a dynamical origin of the flow fluctuations in HYDJET++ event generator

HYDJET++ model for the ultra-relativistic heavy-ion collisions: new results and developments

HYDJET++ model combines the description of soft processes with the treatment of hard partons propagating medium. The model is employed for the analysis of PbPb collisions at LHC energies, particularly, the azimuthal anisotropy phenomena, flow, femtoscopy, hard probes. The influence of geometric and dynamical anisotropies on the development of flow harmonics and, simultaneously, on the second- and third-order oscillations of femtoscopy radii were studied. The interplay of soft hydro-like processes and jets is able to describe the violation of the mass hierarchy of meson and baryon elliptic and triangular flows at transverse momentum pT>2 GeV/c, the fall-off of the anisotropic flow harmonics at intermediate transverse momenta, and the worsening of the number-of-constituent-quark (NCQ) scaling of elliptic/triangular flow at LHC compared to RHIC energies. The cross-talk of elliptic and triangular flows leads to emergence of higher order harmonics in the model and to appearance of ridge structure in dihadron angular correlations in a broad pseudorapidity range. Recently, the model was further extended to describe quantitatively the event-by-event fluctuations of the anisotropic flow. The model calculations agree well with the experimental data

STUDI KOMPARASI KONSEP PENDIDIKAN AKHLAK MENURUT KH AHMAD DAHLAN DAN ABDUL MUNIR MULKHAN

MUSTHOFA ANGGA PRASETYO. Studi Komparasi Konsep Pendidikan Akhlak Menurut KH Ahmad Dahlan dan Abdul Munir Mulkhan. Skripsi. Yogyakarta: Jurusan Pendidikan Agama Islam. Fakultas Imlu Tarbiyah dan Keguruan UIN Sunan Kalijaga, 2017. Latar belakang penelitian ini adalah tingkah laku remaja yang menyimpang akhlak sering menimbulkan kegelisahan dan permasalahan masyarakat. Penyimpangan akhlak tersebut biasanya diwujudkan dalam bentuk kenakalan atau kejahatan seperti yang belakangan ini sering terjadi yaitu seks bebas, tawuran remaja atau kampung, pergaulan bebas, penyalahgunaan narkotika, mabuk-mabukan, membolos sekolah, membully teman dan lain sebagainya. Hal tersebut dikarenakan lingkungan pergaulan yang buruk bagi remaja atau peserta didik. Selain itu juga dikarenakan rendahnya atau kurang maksimalnya pendidikan agama khususnya pendidikan akhlak dikalangan remaja atau peserta didik, sehingga nilai-nilai akhlak tidak terinternalisasi secara sempurna. Oleh karena itu, perlu adanya revitalisasi pelaksanaan pendidikan akhlak di sekolah. Pokok permasalahan dalam penelitian ini ialah bagaimana implikasi konsep pendidikan akhlak KH Ahmad Dahlan dan Abdul Munir Mulkhan daapat diterapkan dalam pembelajaran di sekolah. Penelitian ini bertujuan untuk mengetahui persamaan dan perbedaan konsep pendidikan akhlak menurut KH Ahmad Dahlan dan Abdul Munir Mulkhan serta bagaimana implikasinya terhadap pendidikan akhlak saat ini. Penelitian ini merupakan penelitian kepustakaan (library research) karena keseluruhan proses penelitian memanfaatkan berbagai macam pustaka yang relevan terhadap masalah yang diteliti. Adapun pendekatan yang digunakan dalam penelitian ini adalah pendekatan filosofis. Metode pengumpulan data yang digunakan yaitu metode dokumentasi dan wawancara. Studi dokumentasi dilakukan terhadap sumber primer dan skunder, berupa karya-karya tokoh tersebut dan juga tulisan terkait pemikiran tokoh yang relevan dengan penelitian. Penelitian ini menggunakan analisis deskriptif, yaitu analisis yang ditujukan untuk mendeskripsikaan atau menggambarkan pemikiran tokoh tersebut. Hasil penelitian menunjukkan bahwa pemikiran KH Ahmad Dahlan bersifat religious sedangkan pemikiran Abdul Munir Mulkhan bersifat rasionalis. Konsep pendidikan akhlak KH Ahmad Dahlan dan Abdul Munir Mulkhan mempunyai persamaan dan perbedaan. Persamaan tersebut meliputi 1) Pendidik 2) Metode Pendidikan Akhlak. Adapun perbedaan pemikiran keduanya terkait pendidikan akhlak meliputi 1) Pendidikan Akhlak 2) Peserta Didik 3) Materi Pendidikan Akhlak. KH Ahmad Dahlan yang membentuk perilaku keagamaan melalui ilmu dan amal, nilai-nilai akhlak diajarkan kepada peserta didik untuk kemudian dapat diamalkan dalam kehidupan sehaari-hari. Begitu juga Abdul Munir Mulkhan yang berpendapat bahwa pendidikan akhlak itu membentuk perilaku keagamaan peserta didik melalui metodologi keteladanan, pengenalan nilai, stimulai kognitif dan pengembangan empati (peran). Meskipun pendekatan yang dilakukan berbeda, akan tetapi tujuan pendidikan akhlak keduanya sama, yaitu untuk membentuk peserta didik yang berakhlakul karimah
