Expert knowledge acquisition: A methodology for GIS assisted industrial land suitability assessment

Aquestionnaire was designed to acquire expert knowledge concerning land suitability assessment for three industrial land uses. The suitability criteria definition and factor weights collected by the questionnaire were integrated into a GIS framework. The interaction of the expert, questionnaire and GIS modelling environment can benefit the plan making process.     

When hearing clients work with a deaf therapist.

Not being able to hear can present significant challenges for the therapist and for the deaf therapist/hearing client dyad. It can also create opportunities. Although the literature indicates that most culturally Deaf therapists work with Deaf clients due to their mutual use of American Sign Language, I describe (a) the background of an audiologically deaf therapist who relies on speech reading rather than sign language, and (b) this therapist's clinical work with hearing clients. Some of the relational dynamics of these treatments are identified, and I conclude by noting how attention to communication can benefit the work of all psychotherapists.

Calibrating the UHF technique of partial discharge detection usinga PD simulator

The paper describes a technique for simulating the presence of partial discharges in gas-insulated substation (GIS) equipment. The technique employs a pulse generator to inject current pulses through a suitable protrusion. The current pulses have similar temporal characteristics to those produced by an actual discharge event, with the added advantage that their magnitudes can be controlled accurately. Because the pulses are highly reproducible, they are ideally suited for investigating the UHF technique of partial discharge detection. The paper discusses the relationship between the magnitude of the UHF signal received by a coupler and the discharge magnitude. It also shows that the coupler signal is dependent on the protrusion length and on the spatial relationship between the protrusion and the coupler. The implications for practical discharge measurements in GIS also are discussed     

Magnetic resonance imaging of a tissue/implanted device biointerface using in vivo microdialysis sampling

Real-time in vivo images of magnetic resonance contrast agent diffusion from implanted microdialysis probes were obtained by magnetic resonance (MR) microscopy. A gadolinium-containing contrast agent (Gd-DTPA) was infused through microdialysis probes implanted into the subcutaneous space of male Sprague-Dawley rats. The infusion of Gd-DTPA alters the T1 relaxation time for water protons near the microdialysis probe, thus causing an increase in brightness around the probe. Steady state concentration profiles of Gd-DTPA around the microdialysis probe were attained within 10 min. The distance for the diffusion of Gd-DTPA away from the probe was calculated to be approximately 1400 microm on the basis of an image intensity analysis. A 5-cm field of view was used with a 256 x 256 matrix, giving a voxel volume of 0.190 mm3 (195 microm x 195 microm x 5,000 microm). These experiments demonstrate the ability of magnetic resonance microscopy to obtain real-time images of Gd-DTPA diffusion around implanted microdialysis probes. This noninvasive technique may be useful for determining how fibrous encapsulation during long-term implantation may affect localized mass transport at a biointerface.     

Orthogonal planar laser polarization spectroscopy

Planar laser polarization spectroscopy has recently been used to image the hydroxyl radical in combustion for small intersection angles of pump and probe beams. We report an experimental configuration that allows planar laser polarization imaging for perpendicular intersection of pump and probe beams. We demonstrate what to our knowledge is the first planar laser polarization spectroscopy imaging at a 90 degree intersection of pump and probe beams for both linearly and circularly polarized pump beams.     

An adaptive middleware framework for context-aware applications

We describe a middleware framework for the adaptive delivery of context information to context-aware applications. The framework abstracts the applications from the sensors that provide context. Further applications define utility functions on the quality of context attributes that describe the context providers. Then, given multiple alternatives for providing the same type of context, the middleware applies the utility function to each alternative and choose the one with maximum utility. By allowing applications to delegate the selection of context source to the middleware, our middleware can implement autonomic properties, such as self-configuration when new context providers appear and resilience to failures of context providers.

Bulk nanocrystalline aluminum 5083 alloy fabricated by a novel technique: Cryomilling and spark plasma sintering

Dense, bulk nanocrystalline aluminum 5083 alloy was fabricatedvia a combined technique: cryomilling (mechanical milling at cryogenic temperature) to achieve the nanocrystalline Al 5083 powder and spark plasma sintering (SPS) to consolidate the cryomilled powder. The results of X-ray diffraction analysis indicate that the average grain size in the SPS consolidated material is 51 nm, one of the smallest grain sizes ever reported in bulk Al alloys produced by powder metallurgy derived methods. In contrast, transmission electron microscopy (TEM) analysis revealed a bimodal grain size distribution, with an average grain size of 47 nm in the fine-grained regions and approximately 300 nm in the coarse-grained regions. Nanoindentation was used to evaluate the mechanical properties and the uniformity of the consolidated nanocrystalline Al 5083. The hardness of the material is greatly improved over that of the conventional equivalent, due to the fine grain size. The mechanisms for spark plasma sintering and the microstructural evolution are discussed on the basis of the experimental findings.     

Women's working wardrobes: a study using card sorts

Abstract: Picture sorts were used to investigate perceptions of women's office clothes, with a sample of ten male and ten female subjects who normally worked in an office environment. The pictures on the cards were taken from catalogues, and showed women's outfits which might be worn in an office. The subjects sorted the cards repeatedly and generated criteria and categories of their own choice. Some of the criteria and categories had not been previously reported in the clothing research literature. Over half of the male subjects, but none of the female subjects, used ‘married/unmarried woman’ as a sorting criterion, although only one of the images sorted showed a wedding ring. A significantly higher proportion of male than of female subjects used dichotomous categorization (i.e. sorting the cards into two piles for one or more of the criteria). The reasons for this are obscure, but do not appear to be a simple outcome of males not knowing much about female clothing. Previous research into clothing has tended to involve researcher‐centred approaches such as semiotics; the results from this study suggest that there would be advantages in wider use of subject‐centred approaches such as card sorts, both in this domain and elsewhere. It was concluded that card sorts were a useful method and should be more widely used.
