We aim to provide satellite operators and researchers with an efficient means for evaluating mitigating collision risk during the design process of mega-constellations. first establish a baseline various techniques close-encounter prediction collision-probability calculation (Hoots et al. 1984, Gronchi 2005, JeongAhn Malhotra 2015) by carrying out brute-force numerical simulations using sequenc...

"Tanjim" means "belief in the effect of state constellations and movement stars human life terrestrial events" is one topics that have long been interest to humans, including Muslims. The existence some narrations, for or against this issue, has caused jurists Islamic religions disagree about its permission sanctity. As far as it mentioned Shiite jurisprudential books forbidden achievements. is...

In this paper, we examined an effective business model for the ecosystem of Islamic FinTech for Resalat Islamic Bank. The article discussed three phases of Resalat Bank development as a Platform in formulating social business models that require new value propositions, value constellations, and profit equations, and as such, resembles business model innovation. The result of the qualitative met...

We discuss the use of radar satellite constellations, or clusters, for wide-area, high-resolution SAR. These systems are composed of multiple, formation-flying satellites with each satellite having its own, coherent receiver. Increased swathwidth compared to that of traditional SAR is attained by processing the data obtained from multiple satellites. The multi-channel system can also be scanned...

In this paper, we focus on the design of a reliable communication scheme for generic 5-node wireless butterfly networks (WBN). Since the WBN represents a natural extension of the basic two-way relay communication channel, we follow the paradigm ofWireless Physical Layer Network Coding and we show that the design of novel adaptive constellations is desirable to exploit the promising performance ...

We obtain a very simple formula for the generating function of bipartite (resp. quasi-bipartite) planar maps with boundaries (holes) of prescribed lengths, which generalizes certain expressions obtained by Eynard in a book to appear. The formula is derived from a bijection due to Bouttier, Di Francesco and Guitter combined with a process (reminiscent of a construction of Pitman) of aggregating ...
