Cast iron with magnesium induced spheroidised graphite
Cast iron is a brittle material and it is advantageous to process it in such a way to improve its ductility. The brittleness is partially due to the graphite flakes which act as nucleation sites for cracks. Therefore it is an advantage to have the graphite present as spheres. This can be achieved by a heat treatment regime or by the addition of a small amount of Mg which poisons the graphite growth directions.

A Web-Based Virtual Reality Model for Preliminary Estimates of Hi-Rise Building Projects
Cost estimating of a construction project at its early stage is considered to be very important task since it will be used as a base to commit or otherwise not to commit funds to that project. Preparation of a reliableand realistic preliminary estimate to aid the decision makers to commit funds for a specific project is a complicated assignment. Traditional methods and operations produced unsatisfactory aid due to lack ofaccuracy especially in the pre-design stage of a project. This participates
Artificial Design and Planning Support: Interactive Plan Generation andCoordination in Distributed D
In this paper we discuss some basic issues pertaining to artificial plan design as a paradigm for architectural design and urban planning support. We present a model for artificial design generation based on learning control methodologies. Plan design is seen as a search for "coordinated" solutions (changes) that satisfy distributed domain requirements and views expressed by human or artificial agents. Learning control is used as a method to search for solutions that direct partial descriptionsp
Generative CAD Systems
In the new millennium, Computer Aided Design has emerged as the most potent technological innovation in design. As BIM promises to integrate design tasks vertically and horizontally through graceful data exchange, new frontiers appear to researchers and practitioners as potential watershed events of the next decade. Generative approaches, a venerable engagement of computational design, is emerging as one of these. The proceedings of the Generative CAD Symposium held at Carnegie Mellon University
Networked learning
This topic will assist you in developing online communication and Internet learning skills. It is based on the principles of networked learning where individuals establish an online identity and formulate relationships with other people and information to communicate and develop knowledge.

1.051 Structural Engineering Design (MIT)
This course aims at providing students with a solid background on the principles of structural engineering design. Students will be exposed to the theories and concepts of both concrete and steel design and analysis both at the element and system levels. Hands-on design experience and skills will be gained and learned through problem sets and a comprehensive design project. An understanding of real-world open-ended design issues will be developed. Besides regular lectures, weekly recitations and
Creating a Caring School: Toolkit Introduction
This resource is comprised of two companion components, the guide and the toolkit. The guide is intended to assist school leadership and management to understand why and how a particular strategy, method, or idea is useful, and not to be just a how to manual of tips. Yet the resource as a whole is at the same time intended to be relevant at all times to the context and practice of the school management team. Therefore, included in the toolkit component are realistic exemplars, check lists, and a
