There are a couple of ways to solve this real world word problem.
This task is a modeling problem which ties in to financial decisions faced routinely by businesses, namely the balance between maintaining inventory and raising short-term capital for investment or re-investment in developing the busines

In this undergraduate level seminar series topics vary from year to year. Students present and discuss the subject matter, and are provided with instruction and practice in written and oral communication. Some experience with proofs required. The topic for fall 2008: Computational algebra and algebraic geometry.
Seminar for mathematics majors. Students present and discuss the subject matter, taken from current journals or books. Topics vary from year to year. Topic for Fall 2002: Quantum calculus. Instruction and practice in oral communication provided.
Required for all Earth, Atmospheric, and Planetary Sciences majors in the Environmental Science track, this course is an introduction to current research in the field. Stresses integration of central scientific concepts in environmental policy making and the chemistry, biology, and geology environmental science tracks. Revisits selected core themes for students who have already acquired a basic understanding of environmental science concepts. The topic for this term is geoengineering.
This advanced course in anthropology engages closely with discussions and debates about ethnographic research, ethics, and representation.
Seminar for mathematics majors. Students present and discuss the subject matter, taken from current journals or books and write up exercises. Topic for spring 2003: Elementary topological properties of differentiable manifolds. Topics covered include Sard's theorem, the Thom transversality theorem, vector fields and the Poincare-Hopf theorem, and cohomolgy via differential forms. Prerequisites subject to negotiation with the instructor. Instruction and practice in oral communication provided. In this course, students take turns in giving lectures. For the most part, the lectures are based on Robert Osserman's classic book A Survey of Minimal Surfaces, Dover Phoenix Editions. New York: Dover Publications, May 1, 2002. ISBN: 0486495140.
The main objective of this cross disciplinary course is to understand the historical development and the current status of ideas and models, to present and question the constraints from the different research fields, and to investigate if and how the different views on mantle flow can be reconciled with the currently available data.
Examines different types of historical writing: political, social, cultural, demographic, biographical, and comparative. Includes discussion of historical films, fiction, memoirs, and conventional history. Particular attention given to works which have broken new ground in terms of their methodology and approach. Required writing includes brief weekly response papers and a substantial research paper (including proposal, first draft, and final draft), in conjunction with a formal oral presentation. Weekly discussion of readings include periodic student-led discussion and/or presentations. Open to all students, but required of history majors and minors in junior year. This course is designed to acquaint students with a variety of approaches to the past used by historians writing in the twentieth century. The books we read have all made significant contributions to their respective sub-fields and have been selected to give as wide a coverage in both field and methodology as possible in one semester's worth of reading. We examine how historians conceive of their object of study, how they use primary sources as a basis for their accounts, how they structure the narrative and analytic discussion of their topic, and what are the advantages and drawbacks of their various approaches.
Topics vary from year to year. Typical examples from past years: manufacturing strategy, technology supply chains. This seminar will explore the purposes and development of Technology Roadmaps for systematically mapping out possible development paths for various technological domains and the industries that build on them. Data of importance for such roadmaps include rates of innovation, key bottlenecks, physical limitations, improvement trendlines, corporate intent, and value chain and industry evolutionary paths. The course will build on ongoing work on the MIT Communications Technology Roadmap project, but will explore other domains selected from Nanotechnology, Bio-informatics, Geno/Proteino/Celleomics, Neurotechnology, Imaging and Diagnostics, etc. Thesis and Special Project opportunities will be offered.
This course is a seminar in topology. The main mathematical goal is to learn about the fundamental group, homology and cohomology. The main non-mathematical goal is to obtain experience giving math talks.
Innovation in expression -- as realized in media, tangible objects, and performance, and more -- generates new questions and new potentials for human engagement. When and how does expression engage us deeply? While "deep engagement" seems fundamental to the human psyche, it is hard to define, difficult to reliably design for, and hard to critically measure or assess. Are there principles we can articulate? Are there evaluation metrics we can use to insure quality of experience? Many personal stories confirm the hypothesis that once we experience deep engagement, it is a state we long for, remember, and want to repeat. We need to better understand these principles and innovate methods that can insure higher-quality products (artifacts, experiences, environments, performances, etc.) that appeal to a broad audience and that have lasting value over the long term.
This course provides an introduction to important philosophical questions about the mind, specifically those that are intimately connected with contemporary psychology and neuroscience. Are our concepts innate, or are they acquired by experience? (And what does it even mean to call a concept 'innate'?) Are 'mental images' pictures in the head? Is color in the mind or in the world? Is the mind nothing more than the brain? Can there be a science of consciousness? The course will include guest lectures by Professors.
Students learn about electricity and air pollution while building devices to measure volatile organic compounds (VOC) by attaching VOC sensors to prototyping boards. In the second part of the activity, students evaluate the impact of various indoor air pollutants using the devices they made.
Explores photography as a disciplined way of seeing, investigating landscapes, and expressing ideas. Readings, observations, and photographs form the basis of discussions on landscape, light, detail, place, poetics, and ways of seeing, among other issues. A rudimentary understanding of photography and access to a camera required.
Students consider human senses and the many everyday human-made sensors so common in their lives. They learn about the three components of biosensorsâa special type of sensorâand their functions and importance. With this understanding, students identify various organs in the human body that behave as sensors, such as the pancreas. Using LEGO® MINDSTORMS® NXT robots, provided rbt robot programs and LEGO sensors (light, ultrasonic, sound, touch), students gain first-hand experience with sensors and come to see how engineer-designed sensors play important roles in our daily lives, informing people of their surroundings and ultimately improving our quality of life.
