Introduction
The term ?Intelligenz Vuilding? is not any longer a mere slogan used by smart salesmen of commercial and / or office buildings. During recent years it has come to describe a broad engineering concept for building design, construcions and operation, the realization of which challenges architects and engineers involved in the various aspects of building industry. The concept empasizes a multidisciplinary effort to integrate and potimize the building strctures, systems , services and management in
Cavity formation in a tensile loaded alumina particulate composite
Horizontal stringers of fine oxide particles can be seen, parallel to the extrusion direction (horizontal). Under the tensile load, voids have nucleated at the interface between the matrix and the reinforcement particles, and some particle fracture has also occurred. Most voids form on planar faces normal to the tensile load (horizontal), and particularly where stringers of fine oxide particles also intersect the interface. These stringers provide interfacial flaws which may then be preferent
The grain structure of extruded aluminium
The extrusion process leads to the elongation of grains. This micrograph shows a longitudinal section with the extrusion direction lying horizontal. Some large subgrains (or groups of subgrains) are apparent, and some high angle boundary migration has occurred normal to the extrusion direction. Grains near the extrudate centre have a lower aspect ratio.
Experiments as Modus Operandi
Architecture has for too long focused on the presentation of pristine objects and the presentation in drawing form. A critical understanding of the field, however, necessitates a reevaluation of the roles of the process involved in the production of building. Rather than emphasizing surface appearances, an architecture rooted in process aims ultimately at revealing the fundamental and deep structures inherent within the making of architecture. One of the primary tasks of the process is to provok
Interface boundary between h-BN and Si3N4 grains
The micrograph shows a regularly stepped interface boundary between h-BN (precipitate) and Si3N4 grains (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and

Delamination cracks in h-BN particles.
h-BN particles were subjected to compressive stress in the (0001) planes (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Su

Applying object-oriented analysis to the integration of design and construction
This paper implements an Object Oriented Analysis technique to model information related to design and construction. In a previous study, an approach to integrate design and construction processes based upon information analysis and modelling has been proposed. By breaking down the project's vast information into groups of related information, construction related problems have been identified and then traced back too their relevant design processes. This paper models this process using a relati
The Changing Image of the City
The image and structure of a town are constantly subject to a dynamic process of change and continuity. Visual material, such as photographs, historical maps, town plans, drawings and prints, show us the impact of these changes on the image of a town. The main point of departure of this study stems from the question of how this process of change and continuity is visually detectable in a town or city. The fact that the ideas about the appearance of a city (gradually) change, can be read from the
Creativity and Collaboration in Architecture Education in the UAE
A review of national government literature indicates that today?s knowledge-driven economy demands a workforce equipped with complex skills and attitudes. Examples of these skills and attitudes are general problems solving, meta-cognitive skills, critical thinking and lifelong learning. Reviews of the Architecture, Engineering and Construction industry indicates a gap between architecture practice and education. The Egan report states that there is a need for a change of style, culture and p
Fe, C 0.8 (wt%) steel, eutectoid transformation, spheroidised
This steel is of the eutectoid composition. Once the temperature is lowered below the eutectoid temperature, the austenite phase tends to undergo a eutectoid transformation (γ to α + Fe3C). The resultant microstructure, known as pearlite, comprises alternate lamellae of cementite and ferrite. Subsequent to casting, the alloy was normalised (annealed) just below the eutectoid temperature, in order to induce the carbides to take a spherical appearance, which results in the steel becoming softer
Fe, C 0.3 (wt%) steel, spheroidised carbide
A hypoeutectoid alloy (composition less than eutectoid). The first phase formed upon cooling from the austenite phase field is proeutectoid ferrite. Due to the lower solubility of carbon in ferrite, carbon is partitioned into the remaining austenite. At the eutectic point the remaining carbon-enriched austenite transforms to pearlite (a mixture of ferrite and cementite), which is the darker region of the micrograph. The proportion of pearlite is dependent upon the overall composition.Subsequent

Diffusion Across a Sheep Red Blood Cell Membrane
This cell membrane physiology laboratory uses sheep red blood cells to determine: (1) the isotonic and hemolytic molar concentrations of electrolytes and nonelectrolytes, and degree of electrolyte dissociation; (2) the diffusion rate of penetrating molecules of varying size and lipid solubility; and (3) the relationship of molecular size, number of hydroxyl groups, and partition coefficient to diffusion rate. Student research teams then design an experiment using the acquired techniques to deter
Developing a New Approach of Computer Use ?KISS Modeling? for Design-Ideas Alternatives of Form Mass
This research aims at developing a new approach called ?KISS Modeling?. KISS is generally a rule of ?Keep It Simple, Stupid? that will be applied in modeling process investigated and presented by the research. The new approach is implemented in a computer program ?KISS Modeling? that generates three dimensional forms based on simplifying the concept of shape recognition in design. The research, however, does not employ totally concepts of shape recognition or shape understanding in Artificial In
