Urban design analysis by computer

In recent years we have seen a widespread concern among the general public about the architectural qualities of our cities. To urban designers, this means that a greater part of their work will be dedicated to the problems of urban architectural quality. The urban designer already uses the computer to manage all sorts of information such as drawings, word processing, land use data, statistics etc; this raises the possibility of using computers for other types of work. The analysis and evaluation of urban design are to a very large extent based on visual data. Powerful computers are needed to manipulate visual data; the new and more powerful machines which are now being manufactured make it possible to handle such data quickly and efficiently.

The interpretation of complex chromatograms by computer analysis

A computer system is described which has been developed to handle a large volume of data derived from gas chromatographic (GC) and mass spectrometric (MS) analysis of environmental water samples. GC profiles have been quantified to provide a concise presentation of data and MS results, from a limited number of samples, have been used to ascribe probable identification to the components of GC profiles for which no MS analysis was performed. The statistical analysis of analytical performance characteristics provides the basis for the method adopted for cross referencing MS and GC data.

Improved facility management at landfills and waste disposal sites by cover system design analysis

The cover system is a key factor in the management of waste disposal sites. Traditional methods of cover design based on empirical and semi-quantitative analysis have been improved upon by the effective use of models to assess the evapotranspiration, runoff, and infiltration volumes associated with different cover configurations. The Hydrologic Evaluation of Landfill Performance (HELP) model developed for the United States Environmental Protection Agency allows cover performance prediction with a sound technical basis. The HELP model was used to assess four alternative cover designs ranging from simple, two-layer systems to more complex systems incorporating multiple drainage layers and synthetic membrane barriers. A sensitivity study was performed to determine the relative imcorporating cover design parameters such as clay barrier thickness and hydraulic conductivity, synthetic membrane leakage factor, and the length and slope of drainage layers. The results of the study can be used to identify cover designs that reduce infiltration, increase evapotranspiration, and provide manageable volumes of surface runoff within the site vicinity. The modelling indicated that more complex cover systems are not necessarily superior to simpler ones. Efficient cover systems can be achieved by concentrating the engineering design effort on several critical parameters such as the hydraulic conductivity of clay barriers and the leakage factor of synthetic membranes. Other factors, commonly considered important, such as clay barrier thickness and drainage layer design, appear to be less significant.
