Detailed design of a space based solar power system

Abstract

Based Solar Power (SBSP), which involved collecting solar power in orbit and then transmitting that power to the surface. However, to this day, despite a lot of discussion about SBSP, there have been no SBSP watts transmitted to the Earth's surface. The International SBSP Initiative (ISI) demonstration is being developed by students at San Jose State University along with members of the NASA Space Portal to beam SBSP watts to the Earth's surface. The ISI demonstration is being developed based on previously designed technologies and concepts to beam power to the surface using a laser. This thesis discusses the detailed design of the ISI, examining the four main system components: the laser system, the instrument bus, the acquisition, tracking and pointing/safety system, and the ground station receiver. It also discusses the design tools that were developed and utilized for this design. From these design tools, the ISI is shown to need a 9.82 m diameter ground receiver for a laser beam generated with 75 cm diameter optics. The thesis also includes preliminary analysis of the ISI system, showing the critical design points for a potential ISI system.

Analytical results for the Sznajd model of opinion formation

“…We should also mention the well studied voter model [3,42,43,44], which is very similar in spirit to the Sznajd model. Indeed, the relation of the two models was studied e. g. in [45] and it seems that Sznajd model reduces to the voter model at least for certain setups (especially using the Ochrombel simplification on a complete graph) while for others the voter model can be generalised so that it includes the rules of Sznajd model as a special case.…”

Occupation measure methods for modelling and analysis of biological hybrid systems

“…In the biological systems modelling literature, it is common to synthesise parameters using a Monte-Carlo sampling of the parameter space, which is validated then by numerous simulations. An important effort to formalize and validate the parameter synthesis of biological models has been made in works such as Donzé (2010); Mobilia (2015); Dreossi (2016); Beneš et al (2016), or Rumschinski et al (2010). Other such as Cardelli et al (2017) or Bartocci et al (2013) design ODE models satisfying sets of temporal constraints.…”
