A Robot in Kindergarten
These thought are the result of work in progress, started in 1999, within the scope of the Trás-os-Montes Digital/SCETAD, project (sub-project: ICEI – Computers in Early Childhood Education Contexts). The work took place in Portuguese kindergarten rooms, with children aged 3, 4, 5 and 6. The ICEI sub-project aims to promote the use of ICT in a playful but pedagogical way, be it free or directed. This use is intended to occur within the scope of activities developed for the micro-spaces of the

Floodplain Modeling
Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in an aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.

Fascinating Friction!
In this activity, students use wood, wax paper and oil to investigate the importance of lubrication between materials and to understand the concept of friction. Using wax paper and oil placed between pieces of wood, the function of lubricants between materials is illustrated. Students extend their understanding of friction to bones and joints in the skeletal system and become aware of what engineers can do to help reduce friction in the human body as well as in machines.

Alternative Strategies to the Use of Vertebrates in Undergraduate Physiology Labs
There are many reasons to seek alternatives to the use of vertebrates, including cost and concerns with use of vertebrates in undergraduate laboratories. This major workshop explores examples of alternatives, including: a) an exploration of thermoregulation without using animals at all, b) an investigation of actomyosin function and membrane excitation using giant alga, and c) using insects to investigate taste receptors and digestion. This workshop explores the importance of providing good back

Absolute coverage measurements of ultrathin alkali-metal films on reconstructed silicon
Metal/semiconductor interfaces, particularly those involving Si, are of great technological and scientific interest. In atomically abrupt interfaces, many properties are determined by interatomic interactions over a few layers, i.e., over ~1 nanometer. The initial stages of growth of an atomic layer related to structural and electronic properties are thus important to thin film behavior. Surface science studies on metal-semiconductor systems often lead to contradictory conclusions regarding bond

Fundamentals of Compressible Flow Mechanics
This book deals with an introduction to the flow of compressible substances (gases). The main difference between compressible flow and almost incompressible flow is not the fact that compressibility has to be considered. Rather, the difference is in two phenomena that do not exist in incompressible flow. The first phenomenon is the very sharp discontinuity (jump) in the flow in properties. The second phenomenon is the choking of the flow. Choking is when downstream variations don't effect the fl

Photoelectric Effect Virtual Lab
The Photoelectric Effect Virtual Lab was designed with the intent that students and teachers might explore one of the most important, non-classical, behaviors of light - the photoelectric effect. The ability of light, under the right conditions, to liberate electrons from the surface of metals, was one of the most profound mysteries of the late 19th and early 20th centuries. In this Virtual Lab, students will graphically explore the behavior of light with metals.

Biblindex
BIBLindex is an online resource supported by the French Institute of Christian Sources. Ultimately, it aims to permit users to identify biblical quotations in all Jewish and Christian literature of Late Antiquity and the Middle Ages (from the beginning of the Common Era until 1400). It is already possible to search a database of around 400,000 biblical references in works from a wide range of authors, including Clement of Alexandria, Origen, Gregory Nazianzen, Gregory of Nyssa, and many others.

Quantum Transport: Atom to Transistor
The development of "nanotechnology" has made it possible to engineer materials and devices on a length scale as small as several nanometers (atomic distances are ~ 0.1 nm). The properties of such "nanostructures" cannot be described in terms of macroscopic parameters like mobility and diffusion coefficient and a microscopic or atomistic viewpoint is called for. The purpose of this course is to convey the conceptual framework that underlies this microscopic theory of matter which developed in cou

Algorithms
The design of algorithms is studied, according to methodology and application. Methodologies include: divide and conquer, dynamic programming, and greedy strategies. Applications involve: sorting, ordering and searching, graph algorithms, geometric algorithms, mathematical (number theory, algebra and linear algebra) algorithms, and string matching algorithms. Analysis of algorithms is studied - worst case, average case, and amortized - with an emphasis on the close connection between the time co
