Trimodal interpretation of constraints for planning

Constraints are used in the CAMPS knowledge based planning system to represent those propositions that must be true for a plan to be acceptable. CAMPS introduces the make-mode for interpreting a constraint. Given an unsatisfied constraint, make evaluation mode suggests planning actions which, if taken, would result in a modified plan in which the constraint in question may be satisfied. These suggested planning actions, termed delta-tuples, are the raw material of intelligent plan repair. They are used both in debugging an almost-right plan and in replanning due to changing situations. Given a defective plan in which some set of constraints are violated, a problem solving strategy selects one or more constraints as a focus of attention. These selected constraints are evaluated in the make-mode to produce delta-tuples. The problem solving strategy then reviews the delta-tuples according to its application and problem-specific criteria to find the most acceptable change in terms of success likelihood and plan disruption. Finally, the problem solving strategy makes the suggested alteration to the plan and then rechecks constraints to find any unexpected consequences

Inclusive Ecocentric Education

Global Eco-Trails (GET) is an ecocentric education school based in BC, Canada offering short cross-cultural environmental wilderness expedition programs in Thailand, Ecuador and Spain, and a full time K-9 alternative ecocentric school program in Canada. The organization has decided to take a deep look at the culture and progeny of its programs as it seeks to address the problem of practice of how to redesign their ecocentric education programs to more fully realize the goal of being fully inclusive in access and approach in terms of gender, the environment, non-Euro/Euro-North American cultures, and marginalized identities. The ultimate goal is to bring the programs to the forefront of contemporary education by providing a scalable model that can be adapted around the world providing a fully inclusive education system based on ecocentric and social learning principles and values. GET believes that the earth and society needs a new education model for the Anthropocene/Capitalicene. A multicultural/multi-demographic laboratory in the real-world (LRW) series of programs is proposed as the first step in a process to build a foundation from which to create curriculum and methodologies. These GET programs will practice Indigenous/nonindigenous co-teaching/management and through a critical pedagogy process seek inclusivity for all demographics. LRW programs will be led by students and faculty at partner universities\u27 transdisciplinary environmental humanities, and teacher education departments who will conduct the research projects at each session under the direction of GET staff. Community partners will be drawn from environmental education and sustainable living and local community organizations at each program location. GET will build on its 20-year relationship with four communities, in Spain, Canada, Ecuador, and Thailand for whom the Laboratory ecocentric programs will take place each year in Spain and Canada. The K-9 school program being developed will mirror Environmental Humanities university department transdisciplinary areas of study combined with an evolutionary-based education subject model built on hunter-gatherer and horticultural society sustainable living skills and Indigenous pedagogy. Lab programs will take the form of a living prototype sustainable village where students can learn through experience and build within themselves a future vision, aptitude, and practice for positive sustainable change

System Concepts for Bi- and Multi-Static SAR Missions

The performance and capabilities of bi- and multistatic spaceborne synthetic aperture radar (SAR) are analyzed. Such systems can be optimized for a broad range of applications like frequent monitoring, wide swath imaging, single-pass cross-track interferometry, along-track interferometry, resolution enhancement or radar tomography. Further potentials arises from digital beamforming on receive, which allows to gather additional information about the direction of the scattered radar echoes. This directional information can be used to suppress interferences, to improve geometric and radiometric resolution, or to increase the unambiguous swath width. Furthermore, a coherent combination of multiple receiver signals will allow for a suppression of azimuth ambiguities. For this, a reconstruction algorithm is derived, which enables a recovery of the unambiguous Doppler spectrum also in case of non-optimum receiver aperture displacements leading to a non-uniform sampling of the SAR signal. This algorithm has also a great potential for systems relying on the displaced phase center (DPC) technique, like the high resolution wide swath (HRWS) SAR or the split antenna approach in the TerraSAR-X and Radarsat II satellites
