Principles of heat and mass transfer. Steady and transient conduction and diffusion. Radiative heat transfer. Convective transport of heat and mass in both laminar and turbulent flows. Emphasis on the development of a physical understanding of the underlying phenomena and upon the ability to solve real heat and mass transfer problems of engineering significance.

This class serves as an introduction to mass transport in environmental flows, with emphasis given to river and lake systems. The class will cover the derivation and solutions to the differential form of mass conservation equations. Class topics to be covered will include: molecular and turbulent diffusion, boundary layers, dissolution, bed-water exchange, air-water exchange and particle transport.

Design, operation, and management of traffic flows over complex transportation networks are the foci of this course. It covers two major topics: traffic flow modeling and traffic flow operations. Sub-topics include deterministic and probabilistic models, elements of queuing theory, and traffic assignment. Concepts are illustrated through various applications and case studies. This is a half-term subject offered during the second half of the semester.

Through a combination of lectures, cases, and class discussions this subject examines the economic and political conflict between transportation and the environment. It investigates the role of government regulation, green business and transportation policy as facilitators of economic development and environmental sustainability. It analyzes a variety of international policy problems including government-business relations; the role of interest groups, non-governmental organizations, and the public and media in the regulation of the automobile; sustainable development; global warming; the politics of risk and siting of transport facilities; environmental justice; equity; and transportation and public health in the urban metropolis. It provides students with an opportunity to apply transportation and planning methods to developing policy alternatives in the context of environmental politics.

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, strategic planning (e.g., use of SWOT analysis and scenario development), stakeholder valuation and analysis, government-based regulation and cooperation within the transportation enterprise, disaster communications, systems safety, change management, and the impact of globalization.

Approaching transportation as a complex, large-scale, integrated, open system (CLIOS), this course strives to be an interdisciplinary systems subject in the "open" sense. It introduces qualitative modeling ideas and various techniques and philosophies of modeling complex transportation enterprises. It also introduces conceptual frameworks for qualitative analysis, such as frameworks for regional strategic planning, institutional change analysis, and new technology development and deployment. And it covers transportation as a large-scale, integrated system that interacts directly with the social, political, and economic aspects of contemporary society. Fundamental elements and issues shaping traveler and freight transportation systems are covered, along with underlying principles governing transportation planning, investment, operations, and maintenance.

The main objective of this course is to give broad insight into the different facets of transportation systems, while providing a solid introduction to transportation demand and cost analyses. As part of the core in the Master of Science in Transportation program, the course will not focus on a specific transportation mode but will use the various modes to apply the theoretical and analytical concepts presented in the lectures and readings.

Introduces transportation systems analysis, stressing demand and economic aspects. Covers the key principles governing transportation planning, investment, operations and maintenance. Introduces the microeconomic concepts central to transportation systems. Topics covered include economic theories of the firm, the consumer, and the market, demand models, discrete choice analysis, cost models and production functions, and pricing theory. Application to transportation systems include congestion pricing, technological change, resource allocation, market structure and regulation, revenue forecasting, public and private transportation finance, and project evaluation; covering urban passenger transportation, freight, aviation and intelligent transportation systems.

Este curso se imparte en español con subtítulos en inglés, y tanto el material adicional como los ejercicios del curso se ofrecerán en español e inglés. / This course will be taught in Spanish with English subtitles; the required readings as well as the quizzes and other evaluation materials will be provided in both languages.

Desde que en 1954 se realizara el primer trasplante exitoso de un órgano, la cirugía de trasplantes se ha desarrollado espectacularmente brindando esperanza y calidad de vida a muchos enfermos. Mientras esas técnicas y posibilidades terapéuticas avanzan, persisten sin embargo muchos interrogantes sobre el modo en el que los órganos pueden obtenerse lícitamente. Algunos de esos dilemas nos acompañan desde siempre, otros son suscitados por la aparición de fenómenos novedosos como el turismo de trasplantes, las posibilidades que ofrece la donación tras la muerte cardiocirculatoria o los descubrimientos sobre las funciones fisiológicas remanentes en los pacientes diagnosticados en muerte cerebral. En la inmensa mayoría de los países no se pueden comprar y vender órganos. ¿Por qué? A pesar de que muchas personas siguen muriendo a la espera de recibir un órgano, en ningún país se confiscan los órganos de las personas fallecidas. ¿Por qué? ¿Pueden donar los menores? ¿Debemos prescindir de la conocida como “regla del donante cadáver” y permitir la eutanasia para la donación? ¿Con qué límites? ¿De qué manera influye la potencial condición de donante de un órgano en los cuidados que se proporcionan al final de la vida? ¿Cómo evitar el conflicto de intereses entre quienes velan por la vida de los futuros receptores de un órgano y quienes aún se afanan por cuidar a quien va a fallecer de manera irremisible e inminente?

En este curso nos adentraremos en el análisis de ésas y otras cuestiones, pero también introduciremos los nuevos desafíos que para la ética y el Derecho plantean trasplantes novedosos así como la discusión en torno a los criterios de justa distribución de los órganos
 
The first successful organ transplantation was performed in 1954. Since then, the technique has evolved tremendously, giving hope and increased quality of life to many patients around the world. While the technology and drugs advance, several controversies persist regarding the way in which organs may be obtained. Some of these dilemmas arose on the very first day in which organs’ transplantation originated; others have emerged as a result of new phenomena such as transplantation tourism, the new possibilities brought by donation after cardio-circulatory death, or increasing knowledge about the remaining physiological functions detected in patients pronounced as brain dead. Almost all countries in the world forbid the selling of organs. Why? Although many people die while on the waiting lists, in no country does the Government confiscate cadaveric organs. Why? May minors be organ donors? Should we abandon the so-called “dead donor rule” and allow “organ-donation euthanasia”? How does the potential condition of becoming a donor influence the administration of end-of-life care? How should we avoid the eventual conflict of interests between those who care for the life of future recipients of organs and those who are in charge of the dying patient-eventual-donor? In this course we will explore the answers to these questions, and we will also engage in the assessment of the more recent challenges posed by novel transplantation techniques, and, albeit briefly, in the discussion regarding the fair distribution of organs.

In the western world, approximately 10–15% of couples suffer from subfertility. Consequently, over 5 million babies have been born thanks to assisted reproductive technologies, and more than half of those have been born in the past six years alone. This class will cover the basic biology behind fertility and explore the etiology of infertility. We will highlight open questions in reproductive biology, familiarize students with both tried-and-true and emerging reproductive technologies, and explore the advantages and pitfalls of each.
