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

Documenta??o e Comunica??o Digital do Patrim?nio Arquitet?nico Moderno: Centro T?cnico de Aeron?utic
This paper intends to contribute for the analysis of the digital representation applied for documentation, communication and diffusion of architecture as cultural heritage, more specifically the production and communication of informations about buildings and sites of modern movement, arguing the possibilities and limits of this instrumental for the best understanding, recognition, evaluation and diffusion of the architecture on a historiographical perspective. As studies of cases, were selected
A Tool for Typological Analysis
Any design problem is faced drawing from the architect's knowledge both case knowledge and general knowledge. One type of the latter is abstracted from a multiplicity of cases of which the common features are recognised in such a way as to single out a prototype representing in the best way a class of architectural objects. If applied to a set of residential buildings and to the flats in them the analysis is typological and it is one of the fundamental ways of acquiring general knowledge to be u
Learning Virtually: A Paradigm Shift in Design Education
We still think of architectural design education in terms of a "classroom" paradigm, that is, of an instructor teaching design skills to a class of students in a face-to-face format. However, emerging communication and collaboration technologies have created tremendous new opportunities to distribute students and faculty, while maintaining a close personal contact. This paper discusses and characterizes several aspects of the evolving paradigm of teaching design made possible by the ability to
Transforming Grammars for Goal Driven Style Innovation
Shape grammar transformations have been used for developing new design styles by the systematic modification of grammars that encode existing styles. We make use of a style description scheme to aid grammar transformations for goal driven style change. A rule base was authored for the design of Greek temple facades, and was augmented with a style description scheme. These were tested at a student workshop wherein students were asked to develop grammars based on given style briefs. Results gained

Regularity conditions for Banach function algebras
In June 2009 the Operator Algebras and Applications International Summer School was held in Lisbon. Dr Joel Feinstein taught one of the four courses available on Regularity conditions for Banach function algebras. He delivered four 90 minute lectures on and this learning object contains the slides, handouts, annotated slides and audio podcasts from each session.
Banach function algebras are complete normed algebras of bounded, continuous, complex-valued functions defined on topological spaces.
Mathematical analysis
This is a module framework. It can be viewed online or downloaded as a zip file.
It is as taught in 2009-2010.
This module introduces mathematical analysis building upon the experience of limits of sequences and properties of real numbers and on calculus. It includes limits and continuity of functions between Euclidean spaces, differentiation and integration.
A variety of very important new concepts are introduced by investigating the properties of numerous examples, and developing the assoc
International Classification of Function, Disability and Health
This package was originally designed for undergraduates in Medicine at the University of Nottingham. It will also be useful to students in nursing, allied health professions and pharmacy. Practitioners in these fields, who are new to the ICF, will also find it a useful introduction.
It describes the International Classification of Functioning, Disability and Health (ICF), a classification system published by the World Health Organisation to describe health status.
This system is widely used

2.017J Design of Electromechanical Robotic Systems (MIT)
This course covers the design, construction, and testing of field robotic systems, through team projects with each student responsible for a specific subsystem. Projects focus on electronics, instrumentation, and machine elements. Design for operation in uncertain conditions is a focus point, with ocean waves and marine structures as a central theme. Topics include basic statistics, linear systems, Fourier transforms, random processes, spectra, ethics in engineering practice, and extreme events
Mathematical Modeling Using Real Radioactivity Data
In this lab, you can explore how radioactive radiation changes as a function of distance. This curriculum sets the Radioactivity iLab in the context of mathematics curriculum, asking you to consider:
What type of mathematical function governs the intensity of radiation over distance?
Design of Dredging Equipment
Dredging equipment, mechanical dredgers, hydraulic dredgers, boundary conditions, design criteria, instrumentation and automation. Study Goals: The goal of the lecture is to get insight in the procedure for designing dredging equipment based on the knowledge of the dredging processes. Special aspects during design and use of dredging equipment.
Offshore Moorings
The course treats the design of offshore mooring systems literally from the ground up: Starting with the anchor and its soils mechanics in the sea bed, via the mechanics of a single mooring line and system of lines. The course concludes by touching on other mooring concepts and the dynamic behavior of the moored object as a non-linear mechanical system.
Classroom teaching is augmented by laboratory demonstrations and (when possible) a relevant excursion. Study Goals: The classes are set up to gi
Technology Dynamics for Sustainable Innovation
Conducting innovative research is working on the edge of the known and the unknown. In creating new technology the result is never guaranteed. Society faces a tremendous challenge in order to develop in a more sustainable way. What role is there for technology in this process of change? How could we stimulate innovations in technological systems? Study Goals: At the end of the course the student is able to analyse dynamic processes of technological change within industrial corporations. The stud
Cavitation on Ship Propellers
Summary:
Cavitation is the transition of a fluid into vapour due to local reduction of pressure which is generated by high local flow velocities. The transition of a fluid into vapour also occurs during cooking of water by an increase of the local temperature. The term cavitation is generally reserved for conditions in which the temperature of the bulk fluid is not changed.
Although cavitation can occur in many situations this course focuses on ship hydrodynamics and ship propellers. The course

Stress and Health Disparities A Public Health Seminar delivered by Eric G. Walsh, M.D., M.P.H., Monday, April 12, 2010 In the quest for understanding health disparities many explanations have been offered. One new and telling hypothesis is that certain groups of people carry a greater weight of stress proportional to the amount of protective factors offered them in society. Key attributes of this new model include introducing internalized hatred as a function of discrimination to increase allostatic load. While
