Smoking pipe

A smoking pipe is a device made to allow the user to inhale or taste smoke or vapor derived from the burning or vaporization of some substance. The most common form of these is the tobacco pipe, which is designed for use with tobacco, although the device itself may be used with many other substances. The pipes are manufactured with a variety of materials, the most common (as the popularity of its use): Briar, Heather, corn, meerschaum, clay, cherry, glass, porcelain, ebonite, acrylic and other more unusual materials. Other kinds of smoking pipes include:

Pipeline (Unix)

In Unix-like computer operating systems (and, to some extent, Microsoft Windows), a pipeline is a set of processes chained by their standard streams, so that the output of each process (stdout) feeds directly as input (stdin) to the next one. Filter programs are often used in this configuration.

The concept of pipelines was invented by Douglas McIlroy at Unix's ancestral home of Bell Labs, prior to the actual invention of the operating system, and implemented in Unix at his insistence, shaping its toolbox philosophy. It is named by analogy to a physical pipeline. The standard shell syntax for pipelines is to list multiple programs to invoke in one command, separated by vertical bars:

Each program is assumed to take input and give output on its standard streams. Each "|" tells the shell to connect the standard output of the left program to the standard input of the right program by an inter-process communication mechanism called an (anonymous) pipe, implemented in the operating system. Since pipes are unidirectional, data flows through the pipeline from left to right.

Engineering

Engineering is the application of mathematics, empirical evidence and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, and processes.

The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.

The term Engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise".

Definition

The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as:

History

Engineering has existed since ancient times as humans devised fundamental inventions such as the wedge, lever, wheel, and pulley. Each of these inventions is essentially consistent with the modern definition of engineering.

Audio engineer

An audio engineer works on the recording, manipulation, mixing, reproduction, and reinforcement of sound. Audio engineers work on the "...technical aspect of recording—the placing of microphones, the turning of pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer ... the nuts and bolts." Many audio engineers creatively use technologies to produce sound for film, radio, television, music, electronic products and computer games. Audio engineers also set up and operate sound reinforcement systems for concert, corporate, theatre, sporting and other events.

Alternatively, the term audio engineer can refer to a scientist or professional engineer who holds a B.Sc. or M.Sc. who designs, develops and builds new audio technologies working within the field of acoustical engineering.

Audio engineering concerns the creative and practical aspects of sounds including speech and music, as well as the development of new audio technologies and advancing scientific understanding of audible sound.

Cal Poly Pomona College of Engineering

The Cal Poly Pomona College of Engineering is the engineering college at California State Polytechnic University, Pomona (Cal Poly Pomona) located in Pomona, California, United States. With over 5,600 undergraduate students (as of fall 2015), it is the largest engineering college in Southern California, the second largest college of engineering in the California State University system, and the seventeenth largest engineering college in the United States. In 2013 U.S. News & World Report ranks Cal Poly Pomona's undergraduate program 14th in the nation (for Master's-granting universities), and mentions that Cal Poly Pomona "has one of the top ranked engineering programs, and graduates roughly 1 of every 14 engineers in the state of California."

Because of the hands-on approach to academics and undergraduate focus, the college of engineering at Cal Poly Pomona is among the most selective engineering colleges in the nation and most of its departments are currently declared impacted (hold stringent standards for admissions). For fall 2015, the college admitted 45.3 percent of its total freshmen applicants who held an average unweighted GPA of 3.72 (out of 4.00) and SATs of 1178 (out of 1600), making the college admissions process statistically comparable to the University of California campuses at Davis, Irvine, and Santa Barbara.
