Learning to Recommend from Positive Evidence
In recent years, many systems and approaches for recommending information, products or other objects have been developed. In these systems, often machine learning methods that need training input to acquire a user interest profile are used. Such methods typically need positive and negative evidence of the user's interests. To obtain both kinds of evidence, many systems make users rate relevant objects explicitly. Others merely observe the user's behavior, which fairly obviously yields positive e
Interactive learning of nanophysics phenomena
This paper describes a new method of teaching and experimenting nanophysics effects using a nanomnipulator. This nano-manipulator is formed by a multi-sensory platform connected to an AFM and/or to virtual nano-scenes produced by a real-time simulator. The first objective of this work is the evaluation of a custom-made nanomanipulator compared to the use of a classical Atomic Force Microscope (AFM) interface. These instruments are used to teach one-dimensional nano-physical phenomenon, the appro
Clustering Students to help Evaluate Learning
In this paper we show how clustering techniques can be applied to student answers generated from a web-based tutoring tool. In particular we are interested in extracting clusters of students based on the mistakes they made using the tool, with the aim of obtaining pedagogically relevant information and providing this feedback to the teacher. The data we used comes from the Logic-ITA, a web-based tutoring tool to practice formal proofs currently in use in the School of Information Technologies at
Size and Scale
Another good lesson plan from DiscoverySchool.com, the Size and Scale Web site gives teachers a well conceived and thorough activity on the physics of size and scale. Objectives of the lesson include: understanding the relative sizes of bodies in our solar system and the problem of making a scale model of the entire solar system (because the distances in space are so great that even a very small scale model would be too large to be practical). The site contains all the information needed to comp
Liquid Chromatography Books
This site provides a list of books related to liquid chromatography and its applications. While not immediately pedagogically useful, it may be useful to those seeking texts about LC for their own research interests or to provide as references to students.
Basics of Fluid Mechanics
This book describes the fundamentals fluid mechanics phenomena for engineers and others. This book is designed to replace all introductory textbook(s) or instructor's notes for the fluid mechanics in undergraduate classes for engineering/science students but also for technical peoples. It is hoped that the book could be used as a reference book for people who have at least some basics knowledge of science areas such as calculus, physics, etc.

Digital Photogrammetric Restitution of the Pelourinho?s Fa?ades, in Salvador - Bahia, Brazil [Restit
Brazil has so many historical cities with important architectural heritage. Some of them are remains of the colonial times and aggregate beautiful buildings such as, palaces, public buildings and churches in baroque style, legacy of the Portuguese colonization. Despite of its cultural value, most of these building sets are under several kinds of threats. This paper discusses about the experience on digital photogrammetric restitution of the building fa?ades of Pelourinho, a neighborhood in the
Internet Scout Project
The American Institute of Physics (AIP) Scitation website "is the online home of more than 100 journals from AIP, APS, ASCE, ASME, SPIE, and a host of other prestigious science and engineering societies." Everyone can browse the materials by an alphabetical list, publisher, and subject. After completing a quick and free registration form, users have access to a more advanced search engine. While users need to be subscribed to Scitation journals in order to access the full-text articles, they can
Internet Scout Project
Developed by online museum educators, Pieces of Science is described as "an online gallery of sixteen educational resources related to a collection of historical science objects." The sixteen subjects are organized by grade level and include such topics as lighting rods, Apollo 8, a lunar module, Priestleyï¿½s physics project, and penicillin. Each page contains a variety of resources, but the lighting rod page, for example, explains the history of how Benjamin Franklin used lighting rods to s
Internet Scout Project
At this website, the Ames Laboratory describes its research in condensed matter physics, which "is the field of physics that deals with the macroscopic physical properties of matter." Visitors can explore the highlights of the Group's research and current news as well as a calendar of events. The website briefly presents the program director, scientists, visiting scientists, and postdoctoral researchers involved with the Group. Researchers can find information on the Neutron Scattering Society o
Internet Scout Project
The Israel Science and Technology Homepage is the national database and directory of science and technology related sites in Israel. Within this site is the Satellite Images of Israel and the Middle East page. Visitors will find a list of stunning images (acquired from the NASA Johnson Space Center) of the area during the day, at night, its physical features, a topographical view, specific country images, and links to a map of Israel and its cities. Other areas of the site provide lists of organ
Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
What simple idea links together all of chemistry and physics? How can a close study of the macroscopic differences among solids, liquids, and gases support a microscopic model of tiny, discrete, and constantly moving particles? In this session, participants learn how the "particle model" can be turned into a powerful tool for generating predictions about the behavior of matter under a wide range of conditions.,The segment provides examples of probing questions to find out if the student recogniz
AP Physics C
This curriculum covers all of the material outlined by the College Board as necessary to prepare students to pass the AP Physics C exam. This course is designed to acquaint you with topics in mechanics and classical electricity and magnetism. The course covers two semesters. The first semester is devoted to Newtonian mechanics including: kinematics, laws of motion, work and energy, systems of particles, momentum, circular motion, oscillations, and gravitation. The second semester discusses the t
The current online Andes Physics course is intended to be used with most physics textbooks. It supplements the textbook by providing problems for students to solve with the aid of Andes, an intelligent tutoring system developed at the University of Pittsburgh and the United States Naval Academy with funding from the Cognitive Science program of the Office of Naval Research. Students solve typical textbook problems just as they would with pencil and paper, by entering vectors, coordinate systems,
The Chemical Detective
This site is aimed at high school students interested in forensic science. it introduces the visitor to a spectrum of forensic science disciplines that includes DNA, fire and arson, firearms, fingerprints, document examination, and forensic medicine. Each subject is linked to established web sites to provide the user with detailed insights into each forensic discipline. The site also provides actual cases to exemplify forensic applictions in criminal investigations and explores the role of the
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
