Glossary of systems theory A glossary of terms as relating to systems theory. A B C Cascading failure: failure in a system of interconnected parts, where the service provided depends on the operation of a preceding part, and the failure of a preceding part can trigger the failure of successive parts.Closed system: a system which can exchange energy (as heat or work), but not matter, with its surroundings.Complexity: A systemic characteristic that stands for a large number of densely connected parts and multiple levels of embeddedness and entanglement. D Development: The process of liberating a system from its previous set of limiting conditions. E F H I Isolated system: A system in which the total energy-mass is conserved without any external exchange happening. L Lowerarchy: A specific type of hierarchy involving a ‘bottom up’ arrangement of entities such that the few are influenced by the many. M O Open System Model (basics) P R S W
3D printing, laser cutting – design, make & build your own products with Ponoko Sculpteo Summary | Learning Political Economy This is an experimental set of eight Resource blogs, that together with a dialogical and collaborative Service platform, are part of the infrastructure of the Learning Change Project to support and empower a community of change agents on Systemic Change. The Project is the product of a collective action-learning research agenda on society, culture, critical thinking, creativity, innovation, self-organization, rhizomes, networks, systems, complexity, sustainability and futures. The blogs reflect our interest for bottom-up sustainable self-organized communities and systems. The learning about changes is oriented to support social initiatives for inclusive, just, participative, self-reliant, social responsible, creative and innovative sustainable communities, with a system view of learning institutions, embedded within complex socio-cultural environment, facilitating development processes by critical and creative citizens. The Dance of Discovery and Learning Change (Henri Matisse, 1910)
SystemsWiki Home Generation FAB by Matthew Gardiner on Prezi RepRapWiki RepRap is humanity's first general-purpose self-replicating manufacturing machine. RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. RepRap was voted the most significant 3D-printed object in 2017.
