The propagation of planetary-scale waves into the upper atmosphere
An equation governing the propagation of planetary scale waves in the earth's atmosphere is derived by scaling a generalized form of Laplace's tidal equation. Quasi-analytic solutions to the propagation equation are obtained for certain model atmospheres in terms of approximate Hough functions and …

Towards Fast and Adaptive Byzantine State Machine Replication for Planetary-Scale Systems
… of distributed ledger technologies (DLT), planetary-scale BFT SMR ist becoming practical and necessary as it can serve as a consensus primitive to keep the ledger consistent. In our view, the alignment of BFT SMR to DLT brings new challenges, for instance the scalability aspect, where …

The Evolution of the Galapagos Mantle Plume: From Large Igneous Province to Ocean Island Basalt
… plume-derived lavas can clarify important planetary-scale questions relating to the accretion of the Earth, primordial geochemical reservoirs, the fate of subducted materials, planetary differentiation, and convective mixing.

The production of rurality : social and spatial transformations in the Tamil countryside 1915-65
This dissertation advances a critique of the "planetary urbanization" thesis inspired by Henri Lefebvre's writings on capitalist urbanization. Theoretically, it argues that Lefebvrian scholars tend to conflate two distinct meanings of urbanization: a) urbanization understood simply as the …

Interaction between water vapor, radiation and convection in the tropics
… organization simultaneously spans the cloud scale (~ 10km) and the planetary scale (~ 10, 000km). Spatiotemporal variability of tropical water vapor may result from internal instabilities of the atmosphere, arising from the interaction between water vapor, radiation and convection. The …

A Diagnostic and Dynamical Study of the Midwinter Minimum of the Pacific Storm Track
… of MWMIN and the structural features in the planetary-scale flow associated with MWMIN. The results suggest a hypothesis that a significant enhancement of the barotropic damping relative to the baroclinic growth from early to midwinter is an important contributing factor for MWMIN. This …

Scale and stability analysis of selected atmospheric blocking events
… the period 1999-2004, is presented based on the scale and stability analysis, using the NCEP/NCAR re-analysis data. A total of 278 blocking events over the Northern as well as the Southern Hemispheres are analyzed. It is pointed out that globally, over the six year period, 83% of the blocking …

The people in the city of the nation : re-viewing Islamabad's fifth function
… expert. Endowed with a propensity for large-scale planning, both operated with a hubris-laden confidence in developing rational solutions to urban and national dilemmas, technocratic strategies employed as a means to realize grand visions. In this way, Islamabad was conceived by both as part …

Stratosphere - troposphere interaction during stratospheric sudden warming events
… variability. While the upward coupling by planetary-scale Rossby waves in the Northern Hemisphere is well understood, the Southern Hemisphere exhibits traveling wave patterns with a weaker impact on the stratospheric ow. However the tropospheric generation mechanism of these waves is not …

Tropical transport and the seasonal variability of the subtropical "edges" in the stratosphere
… isolated from extratropical air over timescales that are long compared to typical midlatitude mixing timescales. However, there are significant questions regarding the extent to which the tropics may be considered isolated, the mechanisms and variability of this isolation, and the …

Using light underwater : devices, algorithms and systems for maritime persistent surveillance
… collection is a key component for understanding planetary scale physical processes and for studying and understanding marine life. Marine monitoring is an important activity for border protection, port security and offshore oil field operations. However, monitoring is not easy because salt water …

Influence of the Quasi-biennial Oscillation on Interannual Variability in the Northern Hemisphere Winter Stratosphere
… of the QBO on the propagation and dissipation of planetary-scale waves. This behaviour is shown to depend on the seasonal cycle, which argues for the usefulness of considering tropical-extratropical interactions in a GCM context. QBO influence on the interannual variability of the extratropical …

‘Undergoing' as posthuman literacy research in an in/formal settlement primary school in South Africa
… education. ‘Undergoing' refers to what we (on a planetary scale) are becoming, that continuously (re)shapes and (re)orients pre-arranged educational ‘doings'. Research as ‘undergoing' is not about producing knowledge to fill in gaps on a given (transcendently known) plane. ‘Undergoing' troubles …

The response of moist convection and the atmospheric general circulation to climate warming
… surface temperature is investigated. Both cloud-scale and planetary-scale circulations are considered, and a number of different theoretical and numerical tools are employed. First, mechanisms maintaining the thermal stratification of a convecting atmosphere are examined based on simulations of …
