This class surveys the current concepts, theories, and issues in strategic management of transportation organizations. It provides transportation logistics and engineering systems students with an overview of the operating context, leadership challenges, strategies, and management tools that are used in today's public and private transportation organizations. The following concepts, tools, and issues are presented in both public and private sector cases: alternative models of decision-making, st
Ecological Footprint Calculator
This lesson introduces students to the concept of ecological footprint, the overall impact of an individual on the environment. Topics include how ecological footprints are calculated, how individual footprints translate to entire nations or to the Earth.
Rights and justice in international relations
Can the concept of human rights be applied across borders or are rights culturally specific? Is it realistic, or even desirable, to aim at an international system based on universal principles of justice? This unit takes a critical view of the assumption that ‘rights are a good thing’ and looks at the problems that arise when they are applied in the international arena.

TALAT Lecture 3205: The Fluidity of Molten Metals
This lecture introduces the concept of fluidity of molten metal and its influence on the production of castings. The students will understand the relevance of fluidity, the means by which this is measured and the effect of alloy type. Basic understanding of foundry processes, phase diagrams, basic physics and mathematics background is assumed
TALAT Lecture 2403: Applied Fracture Mechanics
This lecture demonstrates how to teach the principles and concepts of fracture mechanics as well as provide recommendations for practical applications; it provides necessary information for fatigue life estimations on the basis of fracture mechanics as a complementary method to the S-N concept. Background in engineering, materials and fatigue is required.
TALAT Lecture 2402: Design Recommendations for fatigue loaded structures
This lecture presents calculation of design stresses for variable stress ratios in practice, explanation on the background of design recommendations; it demonstrates the concept of partial safety factors and supply appropriate background information for aluminium; it enables the designer to evaluate service behavior of structural details on a more sophisticated level applying the same principles as in current design recommendations; it provides understanding of the fatigue design procedure accor
Science in Focus: Energy: Workshop 6. Energy and Systems
Physicists use the concept of a system to trace and quantify the flow of energy. In this session, take a close look at a number of energy systems and see how this concept is closely linked to the Law of Conservation of Energy.,This segment explores the question "What are some practical applications of energy systems?" by visiting classrooms as well as interviewing students and scientists.

The paper discusses mathematical form generation as an academic methodology to develop new approaches to architectural design. The academic design studio ?Math objects? investigates the relationship between complex 3d-surfaces and mathematics in order to expand the formal repertoire of architecture. It claims that the process of form generation can be seen as an autonomous entity, which is independent from an overall strategy or any a priori meaning. Architecture has always originated from a co
TALAT Lecture 2110.01: Automobile brake rotor - LCA in product design
This lecture imparts knowledge about ?production and casting of SiC-particle reinforced aluminium metal matrix composite - PMMC (SiCAl7SiMg); use of Life Cycle Analysis. It provides insight to how to redesign a product using life cycle thinking and LCA to minimize the ecological side effects; the importance of having a thoroughly knowledge about the product's life and its environmental impact. Some knowledge of the concept of the product information structure - "the chromosomes" and f
Semi-manual design support for increasing railwaystation catchment & sustainable traffic routing
The shape ('configuration'), location and direction of the pattern of potential trips by foot or bicycle can help decision makers and designers:- the shape of such a pattern informs about the potential size of a traffic calming area(such as 30Km-zoning),- the location of such a pattern refers to the user-groups and specific destinations that a urban network should bring in safe reach for dictated groups,- the direction of such a pattern, together with shape and location, points to the best routi
XNET2 - Methodical Design of Local Area Networks in Buildings - An Application of the A4 Intelligent
XNET2 is a prototype program, that helps network planners to design Ethernet-conform data-networks for sites and buildings. It is implemented as an example application of the ARMILLA4 Intelligent Design Tool under Knowledge Craft. It is based on a knowledge acquisition phase with experts from DECsite, the network-branch of DEC. The ARMILLA Design Tool is developed on the basis of Fritz Haller's ARMILLA ' a set of geometrical and operational rules for the integration of technical ductwork into a
Physics-based generative design
We present a physics-based generative design approach to interactive form-finding. While form as a product of dynamic simulation has been explored previously, individual projects have been developed as singleton solutions. By identifying categories of computational characteristics, we present a novel unified model that generalizes existing simulations through a constraint-based approach. The potential of interactive form finding simulation is explored through exemplary studies: a conceptual appr
TALAT Lecture 1102: Environmental Factors
This lecture reviews the environmental factors affecting the aluminium industry and the remedial practices followed; it describes the concept of a product life cycle and the importance of recycling; it also describes the secondary aluminium industry, its history, processes, products and structure; it outlines the methodology used to calculate recycling rates and summarizes the scope and size of the European aluminium industry.
ArchiDATA: A Hypermedia Tool for Architecture
Design is a cooperative activity at several levels. At one level, clients, architects, financiers, and construction engineers and contractors, all play important roles in creating the design for the building. At another level, the design team may contain architects, interior and landscape designers, lighting experts, heating, ventilation, and air-conditioning experts, etc. At a third level, individual architects cooperate with computer-based design tools in creating portions of a complex design.
Historical Analysis of Building - (Re)Construction in Olivette Park, USA
From 1959 to 1990, East St. Louis, Illinois deteriorated from an ?All-American City? to a national symbol of urban blight. Located on the Mississippi River, the East St. Louis of today faces severe economic, social, and environmental problems. Nearly onequarter of the city?s work force is unemployed and about 40 percent of families are living below the poverty level. But East St. Louis was not always a distressed community. With strong ties to St. Louis and the surrounding region, East St. Louis
