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

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
No More Fear or Doubt: Electronic Architecture in Architectural Education
Operating electronic and Internet worked tools for Architectural education is an important, and merely a prerequisite step toward creating powerful tele-collabortion and tele-research in our Architectural studios. The design studio, as physical place and pedagogical method, is the core of architectural education. The Carnegie Endowment report on architectural education, published in 1996, identified a comparably central role for studios in schools today. Advances in CAD and visualization, combin
Future Space Cities@Universe (Digi-City Vision)
A template for the future city has been carved into the heavens. Ever since the beginning of humankind, we have looked to the sky for the opportunity to make a new start in our imperfect world. Between the stars and the darkness we have imagined utopias beyond the reach of our travel technologies, colonizing space with our fantasies. Now we are in the first stages of an electronic revolution, but in the future 50 years later we will be in a mega-digital era which we have to predict, work and sea
Application of fuzzy time series to population forecasting
The potential of fuzzy logic application in simulating of demographic processes by the example of population forecasting task hasbeen investigated. The particularities of population as dynamical system functioning under the condition of uncertainty have beenexamined and fuzzy statement problem has been suggested. The strategy of population forecasting using the method of fuzzy timeseries model has been proposed. The simulations on retrospective evaluation of population are carried out and on the
Plate Tectonics: Earthquake Epicenter
This lesson provides an overview of destructive earthquakes and their connection to tectonic movements of the Earth's crust. It includes a discussion of some especially destructive historic earthquakes, and a brief introduction to continental drift.

1784 Mifflin Not Washington President - China Trade
The history of trade with China. President Obama does the introduction. In 1784, our founding father, George Washington, commissioned the Empress of China, a ship that set sail for these shores so that it could pursue trade with the Qing Dynasty. Washington wanted to see the ship carry the flag around the globe, and to forge new ties with nations like China. This is a long video with many names that are probably unknown to most students. It has good visuals, but the fast paced video covers too
