earlier studies have shown conclusively that a tuned liquid damper (tld) is effective for controlling vibrations in structures subjected to narrow-banded wind excitations. a recent numerical study has shown that if the design parameters of a tld are properly set, this device could also be very effective for controlling structural vibration to broad-banded earthquake excitations. here the result...

This paper maps out the design space of urban locationrelated mood self-tracking as starting point for individual and urban reflection: What are the benefits for key stakeholders, and what are system design options? Data-driven reflection here means that reflection is based on data; in this instance taking mood related to public spaces as starting point for reflection, but “attaching” to mood a...

The eruption of the volcano in Iceland has proven once again that while we have increasing control over the environment, we are becoming more dependent and painfully aware that we are at its mercy. In fact, we have been making major efforts to address this issue for almost four decades, ever since sustainability was introduced as an environmental concept. Researchers have been constructing the ...

This emergy-based urban economic account provided a historical portrait of the urban economy and its structures to understand the overload of the biosphere`s assimilative capacity. The basic situation of the urban economy, involving the indigenous resources base, emergy consumption patterns, emergy exports and imports, were investigated, accounted and discussed. Using a series of ratios and ind...

The objectives of the paper are to show how the sustainability of urban settlements can be improved by treating as a variable the design of: (a) property rights to realty, corporations and currencies and: (b) their communication and control governance architecture. System science provides the basis for showing that the governance of complexity is improved by increasing the richness and variety ...

in acceptance-sampling plans, the items of an incoming lot are inspected one by one. if the number of nonconforming items in sample is equal zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be applied for the second sample. in this paper, a mathematical model is developed to design sing...

Growing populations of white-tailed deer (Odocoileus virginianus) in urban areas often conflict with local human interests and present challenges to natural resource managers. Netted-cage traps can be an important tool for management of urban deer populations where traditional control methods may not be appropriate or acceptable. We discuss the design of netted-cage traps, trapping techniques, ...
