Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Geospatial Technologies.The past decade web has seen a major transformations in development and
design to facilitate a user interactive environment commonly referred as Web
2.0. Web 2.0 services include web-based communities, hosted services,
social-networking sites, media-sharing sites, wikis, bogs and mashups.
Member contributions feed these online communities and are the force
behind the increased volume of multimedia resources that are available on
the web. In 2006 Time Magazine selected users of Web 2.0 for ‘esteemed
person of the year’ award for their active involvement in generating web
resources and shaping these resources into collective intelligence
\u27Delivering\u27 Education; Maintaining Inequality. The case of children with disabilities in Afghanistan
Education for children with disabilities in Afghanistan, particularly disabled girls, continues to lag behind despite laudable efforts of the Ministry of Education to promote universal access for all. The opportunity for education constitutes not just a means of achieving learning outcomes but also a space for social interaction, individual development and psychosocial support, which are paramount in Conflict Affected Fragile States (CAFS). However, many persisting barriers still need to be overcome in Afghanistan to allow education for all and change negative attitudes towards education of children with disabilities. In this paper we argue that viewing education as a basic commodity, which is the widespread practice in CAFS, is not conducive to expanding human freedoms and capabilities. More specifically, through analyses of a national survey, we demonstrate that despite considerable resources, increasing access to education in Afghanistan has maintained processes of marginalization of the already excluded
DIII-D research advancing the physics basis for optimizing the tokamak approach to fusion energy
Funding Information: This material is based upon work supported by the US Department of Energy, Office of Science, Office of Fusion Energy Sciences, using the DIII-D National Fusion Facility, a DOE Office of Science user facility, under Awards DE-FC02-04ER54698 and DE-AC52-07NA27344. Publisher Copyright: © 2022 IAEA, Vienna.DIII-D physics research addresses critical challenges for the operation of ITER and the next generation of fusion energy devices. This is done through a focus on innovations to provide solutions for high performance long pulse operation, coupled with fundamental plasma physics understanding and model validation, to drive scenario development by integrating high performance core and boundary plasmas. Substantial increases in off-axis current drive efficiency from an innovative top launch system for EC power, and in pressure broadening for Alfven eigenmode control from a co-/counter-I p steerable off-axis neutral beam, all improve the prospects for optimization of future long pulse/steady state high performance tokamak operation. Fundamental studies into the modes that drive the evolution of the pedestal pressure profile and electron vs ion heat flux validate predictive models of pedestal recovery after ELMs. Understanding the physics mechanisms of ELM control and density pumpout by 3D magnetic perturbation fields leads to confident predictions for ITER and future devices. Validated modeling of high-Z shattered pellet injection for disruption mitigation, runaway electron dissipation, and techniques for disruption prediction and avoidance including machine learning, give confidence in handling disruptivity for future devices. For the non-nuclear phase of ITER, two actuators are identified to lower the L-H threshold power in hydrogen plasmas. With this physics understanding and suite of capabilities, a high poloidal beta optimized-core scenario with an internal transport barrier that projects nearly to Q = 10 in ITER at ∼8 MA was coupled to a detached divertor, and a near super H-mode optimized-pedestal scenario with co-I p beam injection was coupled to a radiative divertor. The hybrid core scenario was achieved directly, without the need for anomalous current diffusion, using off-axis current drive actuators. Also, a controller to assess proximity to stability limits and regulate β N in the ITER baseline scenario, based on plasma response to probing 3D fields, was demonstrated. Finally, innovative tokamak operation using a negative triangularity shape showed many attractive features for future pilot plant operation.Peer reviewe
