TALAT Lecture 1501: Properties, Characteristics and Alloys of Aluminium

Description

This lecture provides a survey of the aluminium alloys available to the user; it describes their various properties; it gives an insight into the choice of aluminium for a proposed application. In the context of this lecture not every individual alloy and its properties have been treated in detail, but rather divided into alloy types with reference to the most commonly used alloys. For further details on alloy properties the reader is referred to available databanks like ALUSELECT of the European Aluminium Association (EAA) or to the European and national materials standards. Good engineering background in materials, design and manufacturing processes is assumed.

IV (MIT) IV (MIT)

Description

Includes audio/video content: AV selected lectures, AV faculty introductions, AV special element video. The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S). In choosing to teach these subjects in a unified manner, the instructors seek to explain the common intellectual threads in these disciplines, as well as their combined application to solve engineering Systems Problems (SP). Throughout the year, the instructors emphasize the connections among the disciplines. Includes audio/video content: AV selected lectures, AV faculty introductions, AV special element video. The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S).

4.411 Building Technology Laboratory (MIT) 4.411 Building Technology Laboratory (MIT)

Description

In this class, concepts of building technology and experimental methods are studied, in class and in lab assignments. Projects vary yearly and have included design and testing of strategies for daylighting, passive heating and cooling, and improved indoor air quality via natural ventilation. Experimental methods focus on measurement and analysis of thermally driven and wind-driven airflows, lighting intensity and glare, and heat flow and thermal storage. Experiments are conducted at model and full scale and are often motivated by ongoing field work in developing countries.

8.251 String Theory for Undergraduates (MIT) 8.251 String Theory for Undergraduates (MIT)

Description

Introduction to the main concepts of string theory to undergraduates. Since string theory is quantum mechanics of a relativistic string, the foundations of the subject can be explained to students exposed to both special relativity (8.033) and basic quantum mechanics (8.05). Subject develops the aspects of string theory and makes it accessible to students familiar with basic electromagnetism (8.02) and statistical mechanics (8.044). This includes the study of D-branes and string thermodynamics. Introduction to the main concepts of string theory to undergraduates.

This course uses the theory and application of atomistic computer simulations to model, understand, and predict the properties of real materials. Specific topics include: energy models from classical potentials to first-principles approaches; density functional theory and the total-energy pseudopotential method; errors and accuracy of quantitative predictions: thermodynamic ensembles, Monte Carlo sampling and molecular dynamics simulations; free energy and phase transitions; fluctuations and transport properties; and coarse-graining approaches and mesoscale models. The course employs case studies from industrial applications of advanced materials to nanotechnology. Several laboratories will give students direct experience with simulations of classical force fields, electronic-structure app This course uses the theory and application of atomistic computer simulations to model, understand, and predict the properties of real materials.
