Blast Load Simulation of Floating Barricade System to Protect Anchored Vessels
Simulation created using the CFD code named CEBAM (Computational Explosion And Blast Assessment Model). CEBAM is capable of simulating blast loads from high explosive, vapor clouds, and bursting vessels. Floating barricade system used to increase standoff and hence reduce blast loading on anchored vessels. Research performed by Risknology, Inc.
Solar System Scavenger Hunt
This OLogy activity gives kids a grounded way to understand the scale of the planets in our solar system. The activity begins with a brief overview that tell them why all planets are round and introduces them to the concept that the planets vary widely in size. Kids are then asked to create a model of the solar system using found objects that match the provided scale in inches for the planets. The activity ends with a series of challenges, which include arranging the planets according to size an
Multi System Degeneration - Cranial Nerves Exam - Trigeminal (CN V) Nerve Sub-exam - Patient 6
Patient's speech is difficult to understand; loss of balance (fell off a truck); occasional choking spells, especially if he eats fast; bladder urgency; and slight impairment of memory. The patient returns for a follow-up with his wife. Since the last visit, he reports no significant changes. His speech is unchanged. Balance is the same with occasional falling. He has occasional choking spells, especially if he eats fast. He continues to have bladder urgency and an occasional accident, but he a
Basic overview of the nervous system and how it functions. Describes a single neuron and how each part functions to help the neuron. Color animation with narration. 1:34 min.
How the Body Works : Units of the Limbic System
The limbic system is a composite structure which lies in the temporal lobes of the brain and in the region of the thalamus. It is concerned with emotions and memory. The amygdaloid bodies are believed to be concerned with aggression. The hippocampus, lying above the parahippocampal gyrus, is concerned with memory. The septum pelucidum is thought to be associated with pleasure reactions. The cingulate gyrus, the fornix and the anterior commissure carry nerve fibers to and from other structures in
How the Body Works : The Limbic System
(This is a 14-second video.) The limbic system, a paired structure, is concerned with memory and emotions. The striped area shows the position of those parts of the limbic system which are hidden by other parts of the brain.
Afta Thoughts On Nafta
Brad DeLong "Afta Thoughts On Nafta" "I was a true believer in NAFTA--the North American Free Trade Agreement. Now my faith is not gone but shaken." So states Brad DeLong, economist and creator of one of the net's most popular weblogs on economics, at www.j-bradford-delong.net. J. Bradford DeLong is Professor of Economics and Chair of the Political Economy major at the University of California at Berkeley. He also serves as a Research Associate at the National Bureau of Economic Research and w
Earth System: El Niño's Influence on Hurricane Formation
This video segment adapted from NASA's Goddard Space Flight Center explains how hurricanes develop and why there are fewer hurricanes in the Atlantic Ocean in strong El Niño years.
Earth System: Drought and Air Quality
This video segment adapted from NASA's Goddard Space Flight Center discusses how a drought can have negative effects locally, for example by increasing the number of forest fires, and also globally, for example by impacting air quality thousands of miles away.
The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our body can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when trying to eat in outer space.
Earth System Science in a Nutshell
This Starting Point module describes what Earth System Science is and why it is useful to employ the Earth System Science perspective in teaching the geosciences. There is information about the different spheres in the system and how they interact. The module also provides links to relevant learning resources and example classes that employ the ESS approach.
Designing an Earth System Course
This Starting Point module describes the process of putting together a course in Earth System Science course. Users will find information on what an ESS course is, why this approach is useful and how to actually create the class. This module supports faculty efforts to structure Earth system science education not only to the needs of geoscience majors, but a variety of different audiences, from non-science majors to pre-service teachers.
Classtalk: A Classroom Communication System for Active Learning
This pdf file is an article describing the advantages of using Classtalk technology in the classroom to enhance classroom communication. Classtalk technology cab facilitate the presentation of questions for small group work, collec the student answers and then display histograms showing how the class answered. This new communication technology can help instructors create a more interactive, student centered classroom, especially when teaching large courses. The article describes Classtalk as a v
Chronos: a network for Earth system history
CHRONOS (Greek: time) aims to create a dynamic, interactive and time-calibrated framework for Earth history. CHRONOS's main objective is to develop a network of databases and visualization and analytical methodologies that broadly deal with chronostratigraphy - that is, with developing a better tool (the time scale) for understanding fundamental Earth processes through time. The CHRONOS platform will provide a new investigative environment for interdisciplinary Earth history research that includ

Methods and Algorithmics for system design
System design is the central topic of this course. We move beyond the methods developed in circuit design (although we shall have interest in those) and consider situations in which the functional behavior of a system is the first object under consideration. There will be an introduction to modeling methods that can be used in the context of system design, followed by a discussion of the main issues that are to be considered when one want to design a system that satisfies a number of relevant pe
System Identification and Parameter Estimation
This course is about non-parametric system identification based on estimators of spectral densities and its application to open-loop and closed-loop systems. Furthermore parameter estimation for linear and non-linear systems playes an important role. At the end of the course, a choice can be made out of three final assignments, for which recorded signals are available. The available demonstration programs have to be adapted in order to estimate proper transfer functions and model parameters. St
How to Make Sentence Fragments Into Complete Thoughts
A musical clip about sentence fragments. Scrolling text on the screen shows examples of sentence fragments and asks the viewer if they are complete sentences. Segment fragments is defined and the examples are edited to make them complete thoughts.
Medicine Games: Immune System Defender
Play a game and find out about a Nobel Prize awarded discovery or work! Ilya Mechnikov, one of the pioneers of immune system research, inserted a thorn into a larva and noticed strange cells gathering around the thorn. The cells were eating any foreign substances entering the ruptured skin. He called these cells phagocytes meaning "devouring cells." He later shared the 1908 Nobel Prize in Physiology or Medicine with another pioneer in the same field, Paul Ehrlich.
Geospatial System Analysis and Design
The course provides the geospatial information system professional an overview of systems analysis and design with emphasis the concepts behind the design process including: business use case modeling, business object modeling, requirements definition, analysis and preliminary design, and, finally, detailed design and deployment. The concepts of the geospatial software and database development process are introduced and the limitations of current modeling techniques are addressed within the spat
