  • The book before the reader is devoted to an exposition of results of investigations carried out mainly over the last 10-15 years concerning certain questions in the theory of quasiconformal mappings. The principal objects of investigation-mappings with bounded distortion- are a kind of n-space analogue of holomorphic functions. As is known, every holomorphic function is characterized geometrically by the fact that the niapping of a planar domain it implements is conformal. In the n-space case the condition of conformality singles out a very narrow class of mappings.

  • AN ASYMPTOTIC RESULT FOR SOME DELAY DIFFERENCE EQUATIONS WITH CONTINUOUS VARIABLE CH. G. PHILOS AND I. K. PURNARAS Received 14 October 2003 We consider a nonhomogeneous linear delay difference equation with continuous variable and establish an asymptotic result for the solutions. Our result is obtained by the use of a positive root with an appropriate property of the so-called characteristic equation of the corresponding homogeneous linear (autonomous) delay difference equation.

  • The Joomla! team was organized and has built a solid foundation; it has continued developing Joomla! 1.0.0 to version 1.0.12, and now has the largest developmental leap so far to Joomla! 1.5 in sight. The users of the system have had just as exciting a year. Many have upgraded their site to Joomla! and a lot of new users have discovered Joomla!, but there are still a lot who don't know the system. Joomla! is by far the most used open-source Web Content Management System in the world.

  • The birth and infancy of entrepreneurship was turned into a specific area of academic study and empirical research quite early. The field greatly evolved, and at the same time, a constant urge to deal with real problems existed, from firm creation to industrial growth, including firm strategy and economic policy. Economic, sociological, and managerial academics began to devise a detailed and interpretative framework for the study of entrepreneurship.

  • This is the standard textbook for courses on probability and statistics, not substantially updated. While helping students to develop their problem-solving skills, the author motivates students with practical applications from various areas of ECE that demonstrate the relevance of probability theory to engineering practice. Included are chapter overviews, summaries, checklists of important terms, annotated references, and a wide selection of fully worked-out real-world examples.

  • Our main empirical ndings are as follows. We nd that a range of nancial and macroeconomic variables prove helpful in selecting funds that are capable of generating future alphas. In particular, we nd evidence that a number of investment strategies (that use macroeconomic variables to predict fund returns) generate out-of-sample alphas from 7-9%/year (after fund-level trading costs and fees), when measured with a single-factor model, and from 12-13%/year with a four-factor model that controls for fund exposures to size, book-to-market, and momentum. ...

  • The matrices that follow are designed as guidelines to assist readers in setting their own bench- mark requirements for SIEM system testing. While this is a benchmark checklist, readers must remember that benchmarking, itself, is governed by variables specific to each organization. For a real-life example, consider an article in eSecurity Planet, in which Aurora Health in Michigan estimated that they produced 5,000–10,000 EPS, depending upon the time of day. 4 We assume that means during the normal ebb and flow of network traffic.

  • Conditioning of Temperature Sensor Output Signals Temperature is a physical variable characterising the flow of heat energy. A temperature measurement process attaches real numbers to the degree of hotness of bodies . Although it can only be measured by suitable sensors the output of these components needs to be presented to the human observer by indicators, recorders or other instruments . To accomplish this further task it is necessary to transform the temperature signal, which is in the thermal energy domain, into another more convenient energy form.

  • There is a global trend of falling household sizes over time, though an international comparison quickly reveals that this reduction is not uniform across countries. Apart from tradition, economic variables are influential in determining how many people live together in one household. We have tried to capture this relationship with a pooled cross-section of 38 countries and data for different years between 1960 and 2006. The dependent variable is the average household size.

  • If you know the present value of a future cash flow, you can determine what a good purchase price should be for that investment. You would not want to pay more than its present value, and would like to pay less than its present value. If you know the key variables, you can use them in a meaningful risk assessment and in negotiations with other parties (buyers, sellers, lenders, investors, landlords, tenants). However, this is where uncertainty enters the picture. Reasonable people will disagree on the projected income from an asset, the projected expenses required...

  • Real estate investment is about creating and adding value through the effective management of property assets. Real estate is fundamentally no different from other mainstream investments: the analysis of property investments can be easily integrated into the capital market framework. Capital asset pricing theory evolved into the capital asset pricing model (CAPM). The CAPM model, described by Franfurter (1995: 104) as the ‘keystone’ of financial theory, has been tested in financial securites (stock exchange) markets over three decades.

  • The CGAP measure of relative macroeconomic performance is attractive for a number of reasons. First, it is based on changes in real GDP, a fundamental variable that should be highly correlated with changes in underlying welfare. Second, our measure should not be unduly sensitive to the stage of an economy’s business cycle going into the crisis. An economy that was overheating prior to 2008 would tend to have a positive unexplained component at that point in time, but it is only the unexplained component during the crisis itself that is considered in our analysis.
