Adaptive Planning in Changing Policies and Environments
<p>Being able to adapt to different tasks is a staple of learning, as agents aim to generalize across different situations. Specifically, it is important for agents to adapt to the policies of other agents around them. In swarm settings, multi-agent sports settings, or other team-based …

Adaptive Planning and Prediction in Agent-Supported Distributed Collaboration.
Agents that act as user assistants will become invaluable as the number of information sources continue to proliferate. Such agents can support the work of users by learning to automate time-consuming tasks and filter information to manageable levels. Although considerable advances have been made …

Image-Guided Proton Therapy For Online Dose-Evaluation and Adaptive Planning
… to account for anatomical changes. This range-adaptive method adjusts the proton beam directly to match the new range to anatomy in the treatment-time image. Using this technique, we were able to reduce normal tissue dose but ended up with increased target heterogeneity and reduced target …

From masterplanning to adaptive planning : understanding the contemporary tools and processes for civic urban order
… of the scope of contemporary urban design and planning tools and processes which can act as alternative qualitative methodologies for the renewal of urban conditions at multiple scales through adaptive methods embracing change, stresses and shocks affecting societies and the city as a growing …

Enhancing maritime defence and security through persistently autonomous operations and situation awareness systems
… environment, the vehicle as well as mission planning and execution. Reasoning about the vehicle capabilities and consequently the actions it can execute is continuous and occurs in real time. Vehicle component faults are incorporated into the reasoning process as a means of driving adaptive …

INFORMATION BASED ADAPTIVE PATH PLANNING AND SAMPLING FOR ENVIRONMENT MONITORING
… processes. We first explain the two adaptive planning algorithms for estimating scalar environmental fields with bounds on the mission time. These algorithms adapt the path during the mission based on the recently collected information. We use Sparse Gaussian Processes for field …

Ai-Enabled Online Plan Adaptation For Mr-Guided Stereotactic Ablative Radiotherapy (Sabr) of Head and Neck Cancer
… organ motion. The emergence of MR-guided adaptive radiotherapy (ART) has the potential to further improve the SABR of HNC, by providing superior visualization of soft tissue and enabling real-time plan adaptation based on the daily anatomical changes of patients. This novel technology has …

Urban Design for Resilience to Multiple Uncertain Hazard Scenarios - Robust Strategies for Coastal Resilience in Westport, Washington
… with local and state experts in pre-disaster planning as well as members of the general public inform the strategies and their integration into an upcoming update of Westport’s Comprehensive Plan (documented in Appendices). The urban design strategies consist of: (i) a suite of built …

Preparedness through partnership : integrating climate change and public health in the City of Boston
… setting, vulnerable populations, and current planning efforts, to identify opportunities for expanded and enhanced action. Lessons for Boston are drawn from an in-depth review of nine other U.S. cities and counties' relevant or innovative programs, strategies, and experiences. Grounded in an …

On efficient approaches to the utility problem in adaptive problem solving
… the utility problem--the realization that adaptive strategies that were intended to improve problem solving performance would actually degrade performance under difficult to predict circumstances--has impeded the development of adaptive problem solving techniques. Even systems designed to …

Climate change adaptation planning under uncertainty in Ho Chi Minh City, Vietnam: a case study on institutional vulnerability, adaptive capacity and climate change governance
… systematically as part of their governance and planning processes. While there is a growing literature on the risks and vulnerabilities related to climate change, as yet there is limited research on the development of institutional responses, the dissemination of relevant knowledge and …

Efficient and Intelligent Radiotherapy Planning and Adaptation
Treatment planning--inverse planning on volumetric tomography images--is the foundation of modern radiotherapy. Contouring planning structures and optimizing plan dose distributions are the two most important components of treatment planning. Treatment planning happens in two stages. The initial …

Adaptive Intensity Modulated Radiation Therapy Planning Optimization with Changing Tumor Geometry and Biology Enforcing Both Cumulative and Fraction Size Dose Constraints
… used to test the effectiveness of the proposed adaptive planning approaches. The computed optimal plans both satisfy cumulative and per-session dose constraints while improving the objective (average tumor dose) as compared to non-adaptive treatment. In addition to tracking tumor geometrical …

Building resiliency or holding off the inevitable? climate adaptation on a dense barrier island in New York
… methods in the analysis of climate adaptation planning on the barrier island of Long Beach, NY five years after Hurricane Sandy left the island devastated. Relying on theories of ecological resiliency that call to mind a 'safe-to-fail' approach rather than engineering resiliency's 'fail-safe' …

Incorporating range uncertainty into proton therapy treatment planning
… issue of robustness in proton therapy treatment planning for cancer treatment. Proton therapy is considered to be advantageous in treating most childhood cancers and certain adult cancers, including those of the skull base, spine and head and neck. Protons, unlike X-rays, have a finite range …

Potential implications of climate change for Rooibos (A. linearis) production and distribution in the greater Cederberg region, South Africa
… of wild and cultivated tea has shown an apparent adaptive advantage of wild tea to tolerate increased aridity with greater water economy, and more reliance on biological nitrogen fixation for N nutrition, indicating a potentially less severe scenario of range contraction for wild types than …
