The Use of Words in Context

The Speech Situation is a term worn with age in the teaching of public speaking in America. That it is comprised of occasion, speaker, and topic is a gross oversimplification. It also includes challenge, anxiety, emotion, fear, responsibility, faults of memory, and instants of pride. Out of the circumstances arise an increase in heart rate, a change in blood pressure, an abnormal pattern of breathing, a noticeable build up in perspiration, and an ongoing evaluation. For students this may be merely a grade or perhaps a series of evaluative remarks, possibly addressed both to the speaker and the other participants, the audience. It may entail a replaying of a record of the speech, indeed a videotape. Most important is the lasting impression that remains with all of the participants. What of the vocabulary of the speaker under the circumstances of the speech situation? This speaker - in the major portions of this work we may say, "this young man" - has spent time seeking an appropriate topic. He has outlined a composition around a central idea or thesis. He has marshaled evidence, details. He has framed an opening paragraph. He has been admonished not to give an essay, but to strive for audience contact, interpersonal communication. He makes his audible approach through his vocabulary and accompanying phonology. Under the tension, the speaker repeats; he adds meaningless vocalizations in periods that might logically be pauses. There are slips of the tongue. At worst, failing, he withdraws to await another day.

Analytical Performance Modeling for Computer Systems, Third Edition

This book is an introduction to analytical performance modeling for computer systems, i.e., writing equations to describe their performance behavior. It is accessible to readers who have taken college-level courses in calculus and probability, networking, and operating systems. This is not a training manual for becoming an expert performance analyst. Rather, the objective is to help the reader construct simple models for analyzing and understanding the systems that they are interested in. Describing a complicated system abstractly with mathematical equations requires a careful choice of assumptions and approximations. They make the model tractable, but they must not remove essential characteristics of the system, nor introduce spurious properties. To help the reader understand the choices and their implications, this book discusses the analytical models for 40 research papers. These papers cover a broad range of topics: GPUs and disks, routers and crawling, databases and multimedia, worms and wireless, multicore and cloud, security and energy, etc. An appendix provides many questions for readers to exercise their understanding of the models in these papers.
