Multivalued Maps

AbstractSome results are presented which establish connections between shape theory and the theory of multivalued maps. It is shown how to associate an upper-semi-continuous multivalued map F: X → Y to every approximative map f = {fk, X → Y} in the sense of K. Borsuk and it is proved that, in certain circumstances, if F is ‘small’ and admits a selection, then the shape morphism S(f) is generated by a map, and if F admits a coselection then S(f) is a shape domination.

This study aims to determine the form of presentation of operas Batak, to describe a way of presenting opera Batak, to describe the form of presentation tortor, and to know the role tortor in staging opera Batak. The theoretical foundation of this research rests on several theories studied, namely the theory of presenting opera Batak, tortor presentation shape theory and theory of the role, with the conceptual framework as a translation problem contained therein. This research was conducted in the street Bah Bolon Kiri (Lorong IV) No. 96 Siantar, in December 2015 to February 2016. The method in this research use descriptive qualitative research methods. The population in this study were 1 informants who are knowledgeable about dance (tortor) in staging opera Batak, 1 director, 1 music player, and the first person who joins the cast in the opera Batak, the number of samples to be studied amounted to 4 people. Data collected through observation, interviews, documentation, and literature study. The results of this study indicate that the form of presentation of opera Batak has important elements, namely: a play (drama), dialog, music (gondang), song (ende) and dance (tortor). Tortor the form of presentation of operas Batak presented three times, at the beginning, middle and end of the scene. Tortor role in staging opera Batak serve to embellish what is dictated by the script becomes symbolic, ensuring variation in the opera  aesthetics, strengthening the scene / act story, become entertainment and become transition between scenes

Uav Swarm

Due to their high mobility, unmanned aerial vehicles (UAVs) can offer better connectivity by complement or replace with the existing terrestrial base stations (BSs) in the mobile cellular networks. In particular, introducing UAV and millimeter wave (mmWave) technologies can better support the future wireless networks with requirements of high data rate, low latency, and seamless connectivity. However, it is widely known that mmWave signals are susceptible to blockages because of their poor diffraction. In this context, we consider macro-diversity achieved by the multiple UAV BSs, which are randomly distributed in a spherical swarm. Using the widely used channel model incorporated with the distance-based random blockage effects, which is proposed based on stochastic geometry and random shape theory, we investigate the outage performance of the mmWave UAV swarm network. Further, based on our analysis, we show how to minimize the outage rate by adjusting various system parameters such as the size of the UAV swarm relative to the distance to the receiver.
