  • Telecommunications is now the fastest changing part of the IT industry, encompassing vast disciplines from distributed systems to real-time applications. I have had the pleasure of being involved in what I believe is the most exciting time in its history. It wasn’t always this way, as telecommunications started out as a novelty: ‘‘An amazing invention, but who would want to use one?’’ – US President Rutherford B. Hayes after making a telephone call from Washington D.C. to Philadelphia. Interestingly however, in 1879, the first telephone was installed in the White House.

  • PRIOR to this, no complete, authentic, and authorized record of the work of Mr. Edison, during an active life, has been given to the world. That life, if there is anything in heredity, is very far from finished; and while it continues there will be new achievement. An insistently expressed desire on the part of the public for a definitive biography of Edison was the reason for the following pages. The present authors deem themselves happy in the confidence reposed in them, and in the constant assistance they have enjoyed from Mr.

  • Discovery, learning, and societal engagement are mutually supportive core missions of the research university. Transfer of knowledge to those in society who can make use of it for the general good contributes to each of these missions. These transfers occur through publications, training and education of students, employment of graduates, conferences, consultations, and collaboration as well as by obtaining rights to inventions and discoveries that qualify for patent protection (intellectual property, or IP) and licensing them to private enterprises.

  • When my grandfather left his uncle’s rural Canadian farm to go to college, he had no idea what the future held. He thought he wanted to become a minister, but what was uppermost in his mind was that, whatever he did, he wanted to fi nd a way to help people. He had no idea he was going to invent the game of basketball. He had no idea even that he was going to go into physical education. He certainly had no idea that the game—intended merely as an activity to fi ll the winter months between the sports of football and baseball for a rowdy class of 18...

  • ABSTRACT This paper is a review of recent trends in United States expenditures on research and development (R&D). Real expenditures by both the government and the private sector increased rapidly between the mid-1970s and the mid-1980s, and have since leveled off. This is true of both overall expenditures and expenditures on basic research, as well as funding of academic research. Preliminary estimates indicate that about $170 billion was spent on R&D in the United States in 1995, with ≈60% of that funding coming from the private sector and about 35% from the federal government.

  • A combinatorial bijection between k-edge colored trees and colored Pr¨ufer codes for labelled trees is established. This bijection gives a simple combinatorial proof for the number k(n − 2)!nk−n n−2 of k-edge colored trees with n vertices.A k-edge colored tree is a labelled tree whose edges are colored from a set of k colors such that any two edges with a common vertex have different colors

  • It is shown that if a d-regular graph contains s vertices so that the distance between any pair is at least 4k, then its adjacency matrix has at least s eigenvalues which are at least 2pd − 1 cos(  2k ). A similar result has been proved by Friedman using more sophisticated tools.More generally, Serre has shown (see [3], [4] ) that for any fixed r and for any infinite family of d-regular graphs Gi, lim inf r(Gi) 2pd − 1. The same result has been proved by Friedman already in [5].

  • Arithmetic is certainly the oldest mathematical activity. The use of the concept of a whole number, numeral systems and the operations of addition, multiplication and division can be found in all civilizations. The invention of zero appears to have come from India. Traces of arithmetical operations have been identified on bones dating back to the Paleolithic Era, on Mesopotamian clay tablets, on Chinese turtle shells and on Egyptian papyrus; the Incas, who did not—so it seems—have writing, did develop an evolved numeral system based on knots in strings, called quipus....

  • Twenty-five years ago, Georges Köhler and César Milstein invented a means of cloning individual antibodies, thus opening up the way for tremendous advances in the fields of cell biology and clinical diagnostics (1). However, in spite of their early promise, monoclonal antibodies (MAbs) were largely unsuccessful as therapeutic reagents resulting from insufficient activation of human effector functions and immune reactions against proteins of murine origin.

  • IF YOU ARE an avid basketball fan, you are certainly aware of my passion for the game that has served me so well. I have been so lucky to have been involved in this game, which was started over a century ago by Mr. Naismith. Interestingly, I bet many of you did not know that Mr. Naismith was a philosopher and a Presbyterian minister as well as a man who was active in many ways in the great game he invented. My journey has taken me through every level involving the roundball game. I’ve had the golden opportunity to coach on the scholastic, collegiate, and professional levels. Also,...

  • Innumerable writers at the end of the nineteenth century have reviewed the changes which in the last fifty years have come over the civilised world. The record indeed is admitted on all hands to be marvellous. Steam, electricity, machinery, and all the practical inventions of applied science have added enormously to the material wealth, comfort, and luxury of mankind. Intellectually, the bounds of pure science have been vastly enlarged; and the blessings of education have been extended to the poorest members of the community.

  • What, So What and Now what. Maybe you’ve heard this before, I certainly didn’t invent it. I learned the technique twenty years ago while training to facilitate team building sessions. We used metaphors to train, activities such as sitting back to back in pairs and describing geometric shapes for partners to draw, or team exercises in Lego construction. The lessons were always about communication and understanding team strengths and weaknesses and we used What, So What, Now What in the debrief to make lessons apparent.

  • The invention of the wheel revolutionized activities as disparate as transportation, war, and the production of pottery (for which it may have been first used). It did not take long to discover that wheeled wagons could be used to carry heavy loads and fast (rotary) potters' wheels enabled early mass production of pottery. But it was the use of the wheel as a transformer of energy (through water wheels, windmills, and even treadmills) that revolutionized the application of nonhuman power sources....
