Industrial process as architectural landscape : a small brewery
An exploration into whether the processes and artifacts of an industrial process can be integrated with the enclosing architecture into a mutually-enriching landscape. The particular vehicle for this exploration is the design of a moderately small brewery in Lowell, Massachusetts. To expand the …

An evaluation of task analysis techniques for industrial process control
… they do not act as tools to aid the design process or the designer. The present thesis examines the use of task analysis in a process control context, and in particular the use of task analysis to specify operator information and display requirements in such systems. The first part of the …

The development of an industrial process to produce AC γ-linolenic acid using Choanephora cucurbitarum
… capable of yielding a high level of γLA in an industrial fermentation. Thirty-nine fungal strains were screened under shake flask conditions. The major criteria used in evaluating these strains were, the yield of γLA per unit volume (g/l) and γLA as a percentage of fatty acids, which is …

Towards the separation of linear α-olefins from industrial process streams using transition metal stationary phases
The use of silver modified stationary phases for the separation of olefins from hydrocarbon mixtures was investigated. Gas solid chromatography (GSC) was found to be a quick and efficient technique for screening ion exchange resins and zeolites as potential support materials in olefin separation. …

Development of new late transition metal catalysts for the oligomerisation of ethene
… of ethene to linear l-alkenes is an important industrial process. The recent discovery of iron and cobalt bisiminopyridyl and nickel and palladium a-diimine catalysts for the polymerisation and oligomerisation of l-alkenes has stimulated interest in the use of late transition metals as …

The production of clinical dextran using membrane processes
… controlled. Dextran is presently fractionated industrially using ethanol precipitation. The aim of this work was to develop an ultrafiltration system which could replace the present industrial process. Initially these molecular weight (MW) bands were removed using batch ultrafiltration. A large …

Pseudo-concurrent programming for real-time process control applications
… use in online system maintenance of real-time, industrial process control systems is presented. The monitor is written in PLM86 for use in an Intel 8086 based system in which system software is organized into a set of foreground interrupts and an infinite background loop. The monitor, which …

Acid catalysed alkylation of diphenyl ether with methanol over shape-selective zeolites
… (typically 300°C and more). To date, only one industrial process is known which is selective to p-cresol but has the disadvantage of co-formaiton of inorganic salt, which is costly to dispose of.

Development of a test protocol for industry to predict and optimise flow behaviour of blended powders utilising particle to bulk scale models
… the blends which show good flow behaviour in the industrial process lines and define the desirable standards for blends with poor flow behaviour. However, the current process of reformulation is basically a trial and error procedure based on the prior experience of the formulator with other blends …
