Why not Artificial Consciousness or Thought?

The purpose of this article is to show why consciousness and thought are not manifested in digital computers. Analyzing the rationale for claiming that the formal manipulation of physical symbols in Turing machines would emulate human thought, the article attempts to show why this proved false. This is because the reinterpretation of designation and meaning to accommodate physical symbol manipulation eliminated their crucial functions in human discourse. Words have denotations and intensional meanings because the brain transforms the physical stimuli received from the microworld into a qualitative, macroscopic representation for consciousness. Lacking this capacity as programmed machines, computers have no representations for their symbols to designate and mean. Unlike human beings in which consciousness and thought, with their inherent content, have emerged because of their organic natures, serial processing computers or parallel distributed processing systems, as programmed electrical machines, lack these causal capacities.     

The Privatisation of Public Property: the Development of a Shopping Mall in Sydney and its Implications for Governance through Spatial Practices

This article examines the planning application and current operation of a new shopping mall in Sydney. I use this analysis to argue that the owners of the mall, Westfield, govern, through spatial practices, the physical space in the mall and the shopping practices of the people who enter the mall. By the term govern I mean the spatial practices by which Westfield controls the shopping area of the mall. I follow the idea of governance inspired by the governmentality literature to show that those connected with the mall are shaped by spatial practices which envisages subjects which are morally free and yet are shaped by shopping mall practices (Foucault, 1975, 1980).

By these spatial practices, I argue, Westfield creates a certain ambience in the mall, which conveys the message that the mall is an attractive and safe location, which welcomes certain customers and excludes others. This collective impression of mall atmosphere, I argue acts as a spatial practice, which in effect governs the mall.

One of the features of shopping malls is that public or civic space is replaced with 'semi-public space' owned by developers. In this context the protection of private property has coalesced with the preservation of public order (Gray and Gray, 2000, p. 23). In shopping malls people considered disruptive to shopping are excluded and shops found in the high street such as pawnshops and second-hand bookshops are not granted a tenancy. Other unwelcome folk include the homeless and groups of teenagers.

n this article I plan to analyse the spatial practices which restrict full public access to such places as the Hornsby shopping mall. Accordingly, I firstly show that the concept of property should rightly be seen as containing social ideas, secondly I discuss the nature of spatial practices, which materially and discursively lead to the exclusion of certain people and thirdly, describe notions of community which help define who are proper mall entrants.     

An optimization strategy for nonlinear simulated moving bed chromatography: Multi-level optimization procedure (MLOP)

This paper presents a multi-level optimization strategy to obtain optimum operating conditions (four flow-rates and cycle time) of nonlinear simulated moving bed chromatography. The multi-level optimization procedure (MLOP) approaches systematically from initialization to optimization with two objective functions (productivity and desorbent consumption), employing the standing wave analysis, the true moving bed (TMB) model and the simulated moving bed (SMB) model. The procedure is constructed on a non-worse solution property advancing level by level and its solution does not mean a global optimum. That is, the lower desorbent consumption under the higher productivity is successively obtained on the basis of the SMB model, as the two SMB-model optimizations are repeated by using a standard SQP (successive quadratic programming) algorithm. This approach takes advantage of the TMB model as well as surmounts shortcomings of the TMB model in the general case of any nonlinear adsorption isotherm using the SMB model. The MLOP is evaluated on two nonlinear SMB cases characterized by i) quasi-linear/non-equilibrium and ii) nonlinear/nonequilibrium model. For the two cases, the MLOP yields a satisfactory solution for high productivity and low desorbent consumption within required purities.

Energy consumption criteria and labeling program of wet cooling towers in Iran

Increasing concerns about the lack of energy resources, global warming and environmental pollution have pushed the relevant organizations to develop energy saving strategies such as energy labeling programs. In this research, a new energy labeling program is developed and evaluated for the wet cooling towers in Iran. The cooling tower parameters, including its cooling capacity and the fan power consumption, are measured using an experimental setup. The experimental data are standardized to compensate the effect of the ambient wet bulb temperature on the cooling tower performance which cannot be controlled during the experiments. The results show that the cooling tower capacity and the fan power consumption may be correlated properly using a linear function which conducts the authors to present a linear energy index (EI). Based on the statistical analysis of a comprehensive range of products, the energy rating limits are extracted for the main types of cooling towers, including induced draft and forced draft ones. The economical and environmental impression of the program authorization is also discussed in detail. Administration of such program may lead to considerable energy saving in the cooling systems which have major economical and environmental benefits, especially in the large industries.     

Energy optimized-ventilation constrained variable air volume system control

The analytical energy performance of an advanced energy optimized-ventilation constrained control approach to variable air volume systems was compared to four other controls. The other controls are either currently used or have been proposed in the literature. The advanced control demonstrated its potential to meet the ventilation requirements of ASHRAE Standard 62–1989 for every zone of the building with minimal energy consumption.

The analytical work was carried out in a single story prototypical commercial building. The building was analyzed in five US cities to provide insight into the impact of climate on the performance of the advanced control. The advanced control consumed less total energy, considerably less in some cities, than the other four controls. The advanced control provides an excellent opportunity to apply to buildings new automation equipment and software never attempted before.
