Discrete Mechanics and Optimal Control for Space Trajectory Design [PDF]
, 2011 Space trajectory design is often achieved through a combination of dynamical systems theory and optimal control. The union of trajectory design techniques utilizing invariant manifolds of the planar circular restricted three-body problem and the optimal ...

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.Abstract Online adaptive radiotherapy (OART) modifies treatment plans using anatomy‐of‐the‐day imaging, but successful clinical implementation depends on automated planning strategies that can generate high‐quality plans within the constraints of an online workflow. This narrative review compares the automated planning architectures of the Varian Ethos

On the benefit of ∈-efficient solutions in multi objective space mission design [PDF]
, 2008 In this work we consider multi-objective space mission design problems. We will show that it makes sense from the practical point of view to consider in addition to the (Pareto) optimal solutions also nearly optimal ones since this increases ...

Applied Psychology: Health and Well-Being, Volume 18, Issue 3, June 2026.Abstract Emergency management has become a widely discussed topic in recent years, particularly in relation to different types of emergencies such as climate change, natural disasters, public health, and armed conflicts. The Covid‐19 pandemic has triggered unprecedented uncertainty, sparking a global emergency that raised concerns not only about health

Medical Physics, Volume 53, Issue 5, May 2026.Abstract Background Treatment planning in radiotherapy is inherently a multi‐criteria optimization (MCO) problem, as it requires balancing competing clinical goals. Traditionally, the treatment's robustness is not formulated as a part of this decision making problem, but dealt with separately through margins or robust optimization.

Solving for Blameless and Optimal Control Under Prioritized Safety Constraints
Optimal Control Applications and Methods, Volume 47, Issue 3, Page 748-762, May/June 2026.Summary of the proposed method for solving for blameless and optimal control sequences. ABSTRACT In many safety‐critical optimal control problems, users may request multiple safety constraints that are jointly infeasible due to external factors such as subsystem failures, unexpected disturbances, or fuel limitations.

On Parallel and Serial (Dis‐)Aggregation in System Dynamics Models
System Dynamics Review, Volume 42, Issue 2, April/June 2026.ABSTRACT Compartment models are widely used in system dynamics to analyze complex systems. However, determining an appropriate level of aggregation remains a methodological challenge. This paper explores how parallel and serial (dis‐)aggregation affect a model's ability to reproduce dynamics of interest, using the beer distribution game (BDG) as a case

Large Language Models as Calibration Agents in Hydrological Modeling: Feasibility and Limitations
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Large language models (LLMs) represent the forefront of artificial intelligence, exhibiting substantial potential for advancing understanding and reasoning in complex Earth system sciences. Hydrological modeling, essential for water resource management and Earth system knowledge, predominantly relies on traditional calibration paradigms and ...

Approximate solutions in space mission design [PDF]
, 2008 In this paper, we address multi-objective space mission design problems. From a practical point of view, it is often the case that,during the preliminary phase of the design of a space mission, the solutions that are actually considered are not 'optimal'
