Climate projections for the fourth assessment report1 (AR4) of the Intergovernmental Panel on Climate Change (IPCC) were based on scenarios from the Special Report on Emissions Scenarios2 (SRES) and simulations of the third phase of the Coupled Model Intercomparison Project3 (CMIP3). Since then, a new set of four scenarios (the representative concentration pathways or RCPs) was designed4. Clima...

We analyse the structure and chemical enrichment of a Milky Way-like galaxy with a stellar mass of 2 × 1010 M�, formed in a cosmological hydrodynamical simulation. It is disc dominated with a flat rotation curve, and has a disc scalelength similar to the Milky Way’s, but a velocity dispersion that is ̃50 per cent higher. Examining stars in narrow [Fe/H] and [�/Fe] abundance ranges, we find rema...

IMPLEMENTATION ISSUES OF REAL-TIME TRAJECTORY GENERATION ON SMALL UAVS Derek Bastian Kingston Department of Electrical and Computer Engineering Master of Science The transition from a mathematical algorithm to a physical hardware implementation is non-trivial. This thesis discusses the issues involved in the transition from the theory of real-time trajectory generation all the way through a har...

We investigated the feasibilities of 2.0∘C and 1.5∘C climate targets by considering the abatement potentials of a full suite of greenhouse gases, pollutants, and aerosols. We revised the inter-temporal dynamic optimization model DICE-2013R by introducing three features as follows. First, we applied a new marginal abatement cost curve derived under moderate assumptions regarding future socioecon...

To serve as a platform for multi-agent research, the BYU MAGICC Lab has created a version of the game of capturethe-flag played in a maze environment that can be configured to model a variety of indoor and urban settings. Each competing team has mobile robots on the ground, a simulated UAV flying overhead, and a remote human commander. Since simultaneous low-level control of all robots is not p...

An intercomparison of eight climate simulations, each driven with estimated natural and anthropogenic forcings for the last millennium, indicates that the so-called ‘‘Erik’’ simulation of the ECHO-G coupled ocean-atmosphere climate model exhibits atypical behaviour. The ECHO-G simulation has a much stronger cooling trend from 1000 to 1700 and a higher rate of warming since 1800 than the other s...

This study explores the integration of ecosystem services and climate change adaptation in development plans for coastal wetlands in Bangladesh. A new response framework for adaptation is proposed, based on an empirical analysis and consultations with stakeholders, using a modified version of the DPSIR (Driver-Pressure-State-ImpactResponse) framework. The framework is tested in the Narail distr...

We introduce a version of the DICE-2007 model designed for uncertainty analysis. DICE is a wide-spread deterministic integrated assessment model of climate change. Climate change, long-term economic development, and their interactions are highly uncertain. The quantitative analysis of optimal mitigation policy under uncertainty requires a recursive dynamic programming implementation of integrat...
