Efficient process optimization
No full textA computer-based system for modelling and optimizing processes is presented. The Design Structure Matrix (DSM) process representation was used to model the processes due to its compact, generic and easily quantifiable nature. The system is capable of calculating a number of process performance metrics that are focussed towards determining the degree of iteration and concurrency within the process, however, the system is easily extendible to include other process performance measurements. The paper describes the use of a Genetic Algorithm (GA) to optimise the sequence of activities with the focus of reducing the amount of iteration by reducing the number of feedback loops and hence reducing the number of initial guesses that are needed in order to undertake highly dependent tasks. Previous investigations have attempted to define a generic structure for combinatorial optimisation using GAs [Todd, D. (1997). Multiple Criteria Genetic Algorithms in Engineering Design and Operation, Ph.D. Thesis, Engineering Design Centre, University of Newcastle upon Tyne, UK.],however this paper demonstrates that the structure of the GA is intrinsically tied to the domain. The focus of this paper was an investigation to determine the most efficient and timely structure for the GA with respect to process optimisation. Additional criteria are included within the system and it is has been demonstrated that the structure is applicable for these criteria. It is therefore assumed that if the criteria are dependent upon the matrix representation, in particular, the sequence of the activities and dependencies, then the GA structure will remain applicable. This assumption was demonstrated to be correct when the DSM and GA were used with the same GA structure to optimise component modularity using different optimisation criteria [Whitfield R.I., Smith J.S. and Duffy A.H.B. (2002). Identifying Component Modules, Seventh International Conference on Artificial Intelligence in Design AID'02, Cambridge, UK,15-17 July 2002.]. The results indicated that the independent position based crossover and shift mutation operators with 60 and 20% probabilities respectively was the most successful structure for the GA. A relationship between the number of activities and the number of evaluations was determined and may be used to eliminate unnecessary computation in future investigations
Roy Whitfield, Guangzhou, China, 1932
No full textRoy Whitfield, Missionary. P. O. Box 53, Canton, China. Brother Whitfield graduated form Harding College in the Spring of 1932. In December of that year he sailed for Canton, China, where he is now laboring in cooperation with Brother and Sister Benson, Brother and Sister Oldham, and Brother Davis. He is sponsored by the West Side Central Church, Detroit, Mich. Brother Whitfield is an all-around man, assisting in the daily Bible School work. The Christian publication work, and the evangelistic work. His personal support is still only partially arranged for, and contributions are needed for the extension [sic] of the work on the field. Offerings may be sent in the form of paper currency, personal check, post office money order, or New York draft. Money may be safely sent directly to Brother Whitfield, or to Claud F. Witty, Box 44, Grand River Station, Detroit Michigan. Brother Whitfield should be addressed at P. O. Box 53, Canton, China. A portrait of Roy Whitfield, American missionary from Churches of Christ to Guangzhou (formerly Canton), China. Roy Whitfield, along with his wife Ruth, came to China in 1932 after being encouraged by George Benson, the first American missionary from Churches of Christ to China, to join him there. The Whitfields evacuated Guangzhou in 1939 after the city was overrun by the Imperial Japanese Army. By the end of 1941, after the United States entered World War II and declared war on Japan, most of the American missionaries from Churches of Christ had evacuated Hong Kong, including the Whitfields.https://digitalcommons.acu.edu/coc_missions_photos/2143/thumbnail.jp

BEAUDOIN Institute for Research in Construction, Institute for Chemical Process and Environmental Technology, National Research Council Canada, Montreal Road, Ottawa ON K1A 0R6, Canada E-mail: [email protected] The synthesis of nanoparticulate #-Al 2 O 3 at 600 # C using a sucrose-based polymer dispersion technique was reported recently by Das et al. [1]. This is of interest, as # -Al 2 O 3 is frequently an unwanted intermediate phase in the conversion of nanoparticulate amorphous alumina into nanoparticulate #-Al 2 O 3 . # -Al 2 O 3 has a relatively disordered structure, but usually requires temperatures in the order of 1100 # C to transform completely to the stable #-Al 2 O 3 phase [2
Unmasking austerity - lessons for Australia
No full textDescription
Austerity policies have fuelled the fire of recession rather than stimulated growth. As a consequence nearly 5.5 million young people are now out of work in Europe and unemployment has reached crisis levels. This is the first of three papers that will examine austerity strategies in Europe and the US and assess their economic and social effects. Subsequent briefings will examine the importance of alternative policies to reconstruct the economy and the public sector.
