2.8 Attenuation and distortion As a signal travels from one device to another it has two problems to overcome. The first is that it gets weaker the further it travels, because some of its energy is absorbed by the transmission medium. This effect is known as attenuation. The extent of attenuation depends on the distance it has to travel and on the type of medium it is travelling through. An amplifier can be used to boost the signal power at the transmitter and receiver, and if necessary at various points in the tran

Consider the following measurements: times to run a marathon temperatures recorded at intervals during a day weight of each bunch of grapes sold at a supermarket yesterday. Time, temperature and weight are all examples of numerical data, but there is not a restricted set of values that they can take.

Sometimes as one quantity increases the other decreases instead of increasing. This is called indirect proportion. Team tasks are often an example of this. The tim 3.4 The equations of uniform motion It has already been said that the straight-line graph of any uniform motion can be represented by an equation of the general form where A and B are constants. Different cases of uniform motion simply correspond to different values f 10.5 Desire to help others This is a less common motivation but it shows not everyone is driven by money. In 1991 the inventor Trevor Baylis saw a BBC documentary about the spread of HIV/AIDS in Africa. What was needed was a way of broadcasting the safe-sex message to people in areas without electricity and where batteries for a radio could cost a month's wages. Solar power wouldn't necessarily help as most people who could get to a radio listened in the evening after work. While absorbing this information he ima 2.2.3 Ecological economics Ecological economics, which formally came to prominence in the mid-1980s, represents a departure from reliance on the use of mainstream economic modelling. Instead, it branches out to actively engage with and incorporate the ethical, social and behavioural dimensions of environmental issues. In short, ecological economics attempts to provide an interdisciplinary approach to environmental issues, whereas environmental economics maintains the primacy of economic modelling. Mark Sag 5.10 Contextualising any particular systems approach The capacity to put any systems approach into context is based on the ability of a practitioner to appreciate their own traditions of understanding and to make connections with the history of particular systems methods or methodologies, or to formulate their own. Above all, there is a need to learn from using them and to achieve outcomes that are agreed by those involved as worthwhile. This is a level of systems practice to which you can aspire.

Although exponentials describe anything that continually doubles or halves, the specific assumption of 'exponential increase' and 'exponential decay' are that these happen during a constant time interval. If the time taken for doubling or halving remains constant, then an exponential increase looks like the thick blue line in Author(s): Learning outcomes After studying this course, you should be able to: describe and use safely eBay and Amazon describe some of the technologies that underpin online shopping and auctions approach new tasks involving online shopping and auctions with more confidence. Great War Centenary 4.3 How effective are antidepressants in general? Despite the rapidly expanding use of antidepressants, to date there is very little evidence that they are effective for the treatment of bereavement or in mild to moderate types of depression. Recent meta-analyses (a technique for combining the results of a number of studies) reported by Joanna Moncrieff and Irving Kirsh, a British psychiatrist and psychologist respectively, show that selective serotonin re-uptake inhibitors (SSRIs), such as paroxetine (Seroxat) and fluoxetine (Prozac), have
Activity 5
This is a course in the construction and application of effective field theories, which are the modern tool of choice in making predictions based on the Standard Model. Concepts such as matching, renormalization, the operator product expansion, power counting, and running with the renormalization group will be discussed. Topics will be taken from factorization in hard processes relevant for the LHC, heavy quark decays and CP violation, chiral perturbation theory, non-relativistic bound states in
This half-semester course provides an introduction to microeconomic theory designed to meet the needs of students in the economics Ph.D. program. Some parts of the course are designed to teach material that all graduate students should know. Others are used to introduce methodologies. Topics include consumer and producer theory, markets and competition, general equilibrium, and tools of comparative statics and their application to price theory. Some topics of recent interest may also be covered.
Connecting customers deeply with a brand is more important than ever before. Hear from Tina Alexander, AVP Digital & Web Marketing, how Celebrity Cruises is reinforcing its “modern luxury” brand promise through a dynamic customer communications app that not only showcases its sailings around the globe, but lets prospects experience them too.
This course provides a graduate-level introduction to stellar astrophysics. It covers a variety of topics, ranging from stellar structure and evolution to galactic dynamics and dark matter.
This course is an introduction to labor economics with an emphasis on applied microeconomic theory and empirical analysis. We are especially interested in the link between research and public policy. Topics to be covered include: labor supply and demand, taxes and transfers, minimum wages, immigration, human capital, education production, inequality, discrimination, unions and strikes, and unemployment.

This class covers quantitative analysis of uncertainty and risk for engineering applications. Fundamentals of probability, random processes, statistics, and decision analysis are covered, along with random variables and vectors, uncertainty propagation, conditional distributions, and second-moment analysis. System reliability is introduced. Other topics covered include Bayesian analysis and risk-based decision, estimation of distribution parameters, hypothesis testing, simple and multiple linear
