The Dose Makes the Poison -- Or Does It?
News reports frequently include stories about toxic chemicals in our food, water, and environment. But what does it mean to label a substance either "toxic" or "nontoxic"?
Toxicity indicates the degree to which a substance is poisonous to biological organisms, including humans. The traditional way to test toxicity is to count how many laboratory organisms die or suffer impaired health when exposed to various concentrations of a substance. However, in recent years this method of estimating the d
Normal Abdominal CT
Set of normal abdominal CT images with various important anatomic structures outlined, for cine viewing to gain a 3D view of the structure and its relationship to adjacent organs.
PhD Forum for Finance and Economics on China 2010
The main theme of this forum is Chinese Financial Reform and 'Sustainable Economic Development Under the Global Crisis'. New perspectives on what we can learn from China and what China might learn from the global financial crisis will be discussed.
An Alternative to Statecraft: should diplomacy adapt to a new world environment?
The European Union is designing a new external action service as part of the changes to foreign policy proposed under the Lisbon Treaty. This lecture examines the contemporary demands on diplomatic missions. Pilar Saborio is the ambassador of Costa Rica to the UK. Georg Boomgaarden is the ambassador of Germany to the UK. Nick Mabey is chief executive of E3G Third Generation Environmentalism. Mary Martin is a research fellow at LSE's Centre for the Study of Global Governance.
Persons unknown
Here, the eponymous ones are everyday folk. Frozen in stasis, and caught in seemingly private moments, they are strangely familiar to us despite the emphasis to the contrary suggested by the title. These images have an immediacy which resonates with our universal experience -e.g. discernible feelings of isolation, of insignificance; anxieties and desires.
Often these subjects are pictured by a window. As evidenced by Friedrich's fascination with window-as-motif (which later influenced Rothko)
Conducting Historical Research: The Case of "Oriental Cairo"
This course guides you through a variety of virtual research projects centered on Douglas Sladen's "Oriental Cairo: City of the 'Arabian Nights'" (1911). It is an introduction to some standard research techniques used by historians as well to using library resources.
Signals and Systems
This course deals with signals, systems, and transforms, from their theoretical mathematical foundations to practical implementation in circuits and computer algorithms. At the conclusion of ELEC 301, you should have a deep understanding of the mathematics and practical issues of signals in continuous and discrete time, linear time invariant systems, convolution, and Fourier transforms.
Naive Room Response Deconvolution
ELEC 301 project by William Howison, Chris Lamontagne, Bryce Luna, and David Newell. Given the output of a system and the system characteristics we can determine the input. We will determine the system characteristics of two rooms by playing an (approximate) impulse and recording the impulse response, and then we will play music into the same rooms and record the output. Using MATLAB we will deconvolve the output with the system response to determine a rough approximation of the input.
Microcontroller and Embedded Systems Laboratory
Basic introduction to microcontroller-based embedded systems development. Includes structured laboratory exercises in the following areas: assembly programming, C language programming, peripheral interfacing, interrupt management, structured programming, task scheduling, simple digital signal processing (DSP), and other related topics. This course assumes no prerequisites and is primarily intended for first and second year engineering students.

Effet d'un dispositif de communication médiatisée synchrone dans une tâche de résolution de prob
Cette étude examine l'incidence d'un dispositif de communication médiatisée synchrone (messagerie instantanée) sur les interactions d'enfants de CM1 dans une tâche de co-résolution d'un problème. Les enfants réalisent une tâche de sélection de phrases importantes d'un récit d'abord individuellement puis avec un camarade de classe. Certains enfants collaborent dans une situation de face à face (7 dyades) et d'autres utilisent un dispositif de communication médiatisée synchrone (8 dy
Modèles de soutien à l'élaboration de scénarios
Les enseignants participant aux nombreux dispositifs d'enseignement à distance sont confrontés à la difficulté d'élaborer leurs activités d'apprentissage, sur support numérique, sous forme de scénarios pédagogiques. Dans cet article, nous proposons un dispositif de soutien à la tâche de conception de scénarios pédagogiques « analyse de documents » basé sur différents niveaux de modèles.,Preprint
La transposition informatique, un nouveau problème pour la didactique
We outline the main features of the computational transposition, a process likely to deeply transform the knowledge to be taught in the course of design and implementation of computer-based learning environments.
Contact and Conquest 1 from the course World Regions, Peoples, and States
This course will provide a framework for recognizing and analyzing the major distinctive regions of the world in comparative context. The most important interrelations between environment, economy, ethnicity, and the national identity and viability of states will be explored.
Introduction de nouvelles représentations dans le micromonde Aplusix
Représentations sous forme mi
Dans le cadre du projet Européen ReMath, nous avons entrepris d’introduire deux nouvelles représentations des expressions algébriques dans le micromonde Aplusix : une représentation mixte Naturelle & Arbre mêlant la représentation naturelle en deux dimensions des expressions algébriques avec une représentation en arbre, et une représentation graphique dans le plan des fonctions et sur la droite des ensembles de solutions des équations. Notre travail emprunte une démarche traditionnel
