Between consultation and collaboration: Self-reported objectives for 25 web-based geoparticipation projects in urban planning

Web-based participatory mapping technologies are being increasingly harnessed by local governments to crowdsource local knowledge and engage the public in urban planning policies as a means of increasing the transparency and legitimacy of planning processes and decisions. We refer to these technologies as “geoparticipation”. Current...

Ethnic Residential Segregation: A Multilevel, Multigroup, Multiscale Approach Exemplified by London in 2011

We develop and apply a multilevel modeling approach that is simultaneously capable of assessing multigroup and multiscale segregation in the presence of substantial stochastic variation that accompanies ethnicity rates based on small absolute counts. Bayesian MCMC estimation of a log-normal Poisson model allows the calculation of the variance...

Probabilistic VHM Failure Envelopes for Skirted Foundations in Spatially Variable, Normally Consolidated Clay

Skirted foundations are used in offshore applications to resist the large horizontal and moment loads that are characteristic of the ocean environment. The ultimate capacity of a skirted foundation subjected to vertical-horizontal-moment (VHM) loading combinations can be described using failure envelopes in VHM load space. This represents a far...

Delivery of Interactive 3D Content via the World Wide Web to Aid in Public Participation in Planning Proposals

Public participation has become an important task for urban planning projects, but due to a lack of interactivity, immersion and feedback on the tools that has been utilized so far for this purpose, the current practice is limited. In providing a web-based virtual solution the current limitations can be reduced and transparency in the planning...

Engine health monitoring using neural networks

Meandering of small streams in Alluvium

Investigations were made at the Hydraulics Research Station of channels which achieved a meander pattern in alluvium through natural processes at discharges between 0.2 and 3.2 cusecs. These followed an earlier programme in which the behaviour of straight channels was studied. Discharge, sediment load, hydraulic gradient and channel geometry...

The calibration of the Canadian 100.000 pound standard of force

A deadweight machine having a capacity range of 4000 to 100.000 pounds has been installed in the structures laboratory. The machine is described with particular reference to the methods used for the calibration of the weights and to a specially constructed equi- arm balance of 2000-pound capacity.
