Joint user association and dynamic resource allocation algorithm for LEO-RAN slicing scenarios by Geng CHEN, Zhiwei XING, Fei SHEN, Qingtian ZENG

“…A joint user association and dynamic resource allocation algorithm was proposed for the slicing scenario of ultra dense low earth orbit-radio access network (LEO-RAN) in order to address the efficient utilization of resources of the integrated terrestrial-satellite network for 6G .Considering the constraints of the minimum rate, maximum delay and resource proportion of different slices, a joint optimization problem of user association and resource allocation was established to maximize the weighted sum of the SE and the differentiated SLA of different slices as the optimization objective.A network slicing algorithm based on multi-agent deep deterministic policy gradient (MADDPG) was proposed to determine the proportion of slicing resources, a Lagrange dual based user association algorithm was proposed to determine the optimal user association policy and the resources were allocated to users by using the round-robin scheduling mechanism.The simulation results show that the proposed algorithm can effectively improve SE while satisfying the differentiated SLA of different slices.Compared with MADDPG-RA, MATD3-LG, MATD3-RA, MASAC-LG and MASAC-RA algorithms, the system utility of the proposed algorithm is improved by 2.0%, 2.3%, 5.7%, 8.7% and 9.4%, respectively.…”

‘Appelsinpiken’ and experiential tourism. Andalusia, ‘geography with a thrill’ by Maria del Carmen Puche Ruiz

“…Seville’s enduring mythical image for tourism, a legacy of 19th century romantic travellers and of films coproduced in the nineteen-fifties and sixties, is brought up to the present day and enhanced with the experiential perspective embodied in this barely known film, which, despite having little resonance in Spain, nonetheless was filmed with the support of the Seville Film Office, the regional government’s TV and radio broadcasting service (Canal Sur) and Jaleo Films. …”

IZBORI U HRVATSKOJ 2020: KRAJ DVOPARTIZMA? by Dejan Bursac

“…Predsednički izbori 2019/2020. godine signalizirali su promenu: po prvi put desni izazivač (u ovom slučaju nezavisni kandidat Miroslav Škoro) uspeva da osvoji preko dvadeset procenata glasova, te efektivno podeli glasove desnice i izazove disrupciju u do tada relativno stabilnom dualnom takmičenju. Škoro je rezultat gradio kako na dugotrajnoj potrazi dela hrvatskih glasača za trećom opcijom, tako i na nizu manjih nacionalističkih i populističkih stranaka i pokreta prisutnih u hrvatskoj politici poslednjih godina. …”
