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

Introduction

This course takes one aspect of the debate concerning the new economy – innovation in the form of the introduction of information and communication technologies – and places it in the historical context of industrial revolutions. Is the new economy really new or ‘just another’ industrial revolution?

3.1 Introduction

The binding of features emerges as being a very significant process when displays are brief, because there is so little time in which to unite them. With normal viewing, such as when you examine the letters and words on this page, it is not obvious to introspection that binding is taking place. However, if, as explained above, it is a necessary precursor to conscious awareness, the process must also occur when we examine long-lived visual displays. Researchers have attempted to demonstrate th

1.3 Unravelling the natures of the large satellites

Before the dawn of the space age, relatively little could be discovered about even the large satellites. Their orbits were well known, and from the subtle orbital perturbations caused by neighbouring satellites it was possible to deduce their masses. Measurements of their sizes enabled densities to be calculated to within about 20 per cent of the currently accepted values for the Galilean satellites, and with rather less certainty for the large satellites of the other giant planets. However,

Lecture 14 (of 16) | Introduction to Robotics
Though this is an entry-level university course, there may be high school students who desire to enter into the field of Robotics, and this course may inspire them.

Lecture by Professor Oussama Khatib for Introduction to Robotics (CS223A) in the Stanford Computer Science Department.

In this segment, Professor Khatib shows a short video on A Finger-Shaped Tactile Sensor Using An Optical Waveguide, then lectures on Robot control and the one degree of freedom.

Columns: Experimenting with Paper Cups
Columns, vertical structural elements that are strong in compression, are good at propping things up. In this video segment adapted from ZOOM, the cast uses paper cups to illustrate what makes columns strong and why they sometimes collapse. By filling the cups with sand, they also show that even hollow columns of a weak material like paper can be made surprisingly strong. Closed captioning included.  Run time 03:03.

5.1 Unity and diversity

The development of a new Europe in the early twenty-first century relates to four main themes that were introduced at the beginning of this unit: unity and diversity, conflict and consensus, tradition and transformation, and inclusion and exclusion.

The striking differences that emerged within Europe (cultural, linguistic, political) have long been associated with the existence of a common framework within which the different parts of Europe were able to develop productively and sustai

1.2.6 Stage 4: Extracting the information

When you are absolutely sure that you know what the diagram or table is all about, start to look for patterns, for discrepancies, for peaks and troughs, for anything unusual. Diagrams and tables are highly patterned information, and they often tell a relatively simple story underneath. Don't get bogged down in the relationship between individual numbers, but look to see whether one relationship is like another, or whether one set of numbers stands out significantly from the rest.

1.1 The WTO

The Ministerial Declaration adopted by WTO members at Doha on 14 November 2001 fails to address the most pressing needs either of the poorest countries or of the world's most vulnerable communities. This means that the people who most need a share in global prosperity are still those least likely to obtain it.

2.3 Trojans

The term Trojan comes from the Greek legend about the fall of the city of Troy. The story goes that, during the seige of the city by the Greeks, a huge, hollow wooden horse was left in front of the gates. The inhabitants thought that it was a peace offering from the Greek army and dragged it into the city. Unknown to them, it was being used to conceal Greek soldiers, who were thus able to use this Trojan horse to enter the city and open the gates for the rest of their army.

7.2 Selected to survive: studies of the PNS

Viktor Hamburger carried out a series of classic embryologieal experiments over a period of about 30 years. He investigated the relationship between the size of target tissue in chick embryos and the size of the pool of neurons that innervated it. His technique was to remove or add target tissue to the tissue which would eventually form a limb, usually the hind limb, and is called the limb bud. A few days later he observed the effect of the tissue addition or removal on the pool of neurons de
