Diretrizez Geom?tricas de Aux?lio ao Processo de Projeto de Edif?cios Residenciais [Geometrical Guid
This paper discusses the basic principles of a geometric method to aid the design process of residential buildings. It makes part of the initial phases of a research whose aim is to develop a computer system to aid the sketching and evaluation of floor plant design of multi-storied residential buildings. The fundamental idea of the research is the existence of some basic patterns of floor plants that reflect the designer?s mental models in this category of building. The models are regarding the

The Life of General George Thomas: Civil War Leader
This video is about the biography of perhaps the most successful general of the Civil War, George H. Thomas, who never lost a battle, and who is little known today is discussed. Explained is the fact, unlike General Lee, he decided that nation was above state and Thomas worked for the Union.  This could be a good research project for students and, perhaps, a debate between Lee and Thomas and which one really did the most for the nation.

Design and Sustainability
Are you aware of the environmental impacts of the stuff you buy? Is that chair you bought made from wood from a sustainable forest, or was it illegally logged ? Or perhaps your TV set's inner parts are too difficult to recycle or cause pollution when it’s dismantled at the end of its life. All this adds up to a huge amount of damage to the planet. This album looks at how designers must respond to the increasingly urgent need for sustainability in product design. Designers now need to come up

11.3 Frequency selectivity

In preceding sections we examined two ways in which the auditory system may code frequency information: the place theory and phase locking. In this section we will look at the psychophysical evidence for place coding on the basilar membrane by examining the ability of the auditory system to resolve the components of sinusoidal waves in a complex sound – a phenomenon known as frequency selectivity.

The perception of a sound depends not only on its own frequency and intensity but also o

2.3 Pressure waves and cycles

In this section we shall be looking at the behaviour and properties of pressure waves in the atmosphere.

Sound originates from the motion or vibration of an object. Let's look at an example of a sound wave generated by a vibrating tuning fork. The prongs of the tuning fork move backwards and forwards cyclically. A cycle is a complete series of movements up to the point where the movement starts to repeat itself. As the prongs of the fork vibrate back and forth they push on neighbouring

6.637 Optical Signals, Devices, and Systems (MIT)
6.637 covers the fundamentals of optical signals and modern optical devices and systems from a practical point of view. Its goal is to help students develop a thorough understanding of the underlying physical principles such that device and system design and performance can be predicted, analyzed, and understood. Most optical systems involve the use of one or more of the following: sources (e.g., lasers and light-emitting diodes), light modulation components (e.g., liquid-crystal light modulato

2.7 Fluorine (F)

Fluoride ions (F) are rare in foods, though some are found in tea and in seafood. However, fluoride does occur naturally in some water supplies, derived from the rocks through which the water flows. Its only role in the body appears to be to help to protect teeth from decay.

The stages of tooth decay are as follows:

  • bacteria live in saliva on teeth (form plaque)

  • produce lactic acid → dissolves calcium salts in tooth

Introduction

This unit explores origins of the Universe by looking in detail at events immediately following the Big Bang. Starting with looking at the cooling of the very early Universe, the unit then moves on to the inflation era, the quark-lepton and the hadron era. Then the unit looks at how fundamental particles began to synthesise to form nuclei, and from here it discusses the development of larger structures like stars and galaxies. By examining closely the forces in play and the interactions of fu

Emperors of the Antarctic – Emperor Penguins
Emperor Penguins are the largest species of penguin
and they live exclusively in Antarctica. These birds stand about 4 feet
tall and are all black with a white patch on their chest which usually
also has hints of yellow. The most amazing thing about these birds is
the commitment they have towards their eggs and their offspring.
Every year, a pair of penguins come together, mate, and once the
female lays the egg; she passes it on to the male. The male peng
