Dual Spin-Cast Thermally Interdiffused Polymeric Photovoltaic Devices
… properties. Bilayer films of sequentially spin-cast donor and acceptor materials are exposed to various heat treatments in order to induce the interdiffusion. The depth profiles show concentration gradients in the donor and acceptor as a result of interdiffusion and these devices show an …

Towards Autonomy: Leveraging Nonlinearity In Predictive And Convex Optimization For Space Vehicle Guidance And Control
… work is further expanded to the formulation of a dual-objective SCP method for far-range spacecraft rendezvous, which enables fuel-optimal solutions that account for disturbances and nonlinear relative motion, offering significant improvements in solve time relative to nonlinear programming …

Development of pulse sequences for hyperpolarized 13C magnetic resonance spectroscopic imaging of tumour metabolism
… sequence acquires a stack-of-spirals at two spin echoes after a single excitation pulse and encodes the kz-dimension in an interleaved manner to enhance robustness to B0 inhomogeneity. Spectral-spatial pulses are used to acquire dynamic 3D images from selected hyperpolarized 13C-labeled …

Equilibria of a Gyrostat with a Discrete Damper
… damper to gain new insights into the dynamics of spin-stabilized satellites. The equations of motion are developed using a Newton-Euler approach, resulting in equations in terms of system momenta and damper variables. Linear and nonlinear stability methods produce stability conditions for simple …
