Nano Technology


Nanotechnology is a pasture of applied science and technology covering a wide range of topics. The main unifying premise is the control of matter on a scale smaller than 1 micrometer, normally between 1-100 nanometers, as well as the manufacture of devices on this same length scale. It is a highly multidisciplinary field, drawing from fields such as colloidal science, device physics, and supramolecular chemistry. Much hypothesis exists as to what new science and technology might result from these lines of research. Some view nanotechnology as a marketing term that describes pre-existing lines of research applied to the sub-micron size scale.

In spite of the apparent ease of this definition, nanotechnology actually encompasses diverse lines of inquiry. Nanotechnology cuts across many disciplines, together with colloidal science, chemistry, applied physics, materials science, and even mechanical and electrical engineering. It could variously be seen as an extension of existing sciences into the nanoscale, or as a recasting of existing sciences using a newer, more recent term. Two major approaches are used in nanotechnology: one is a "bottom-up" approach where materials and devices are built from molecular components which gather themselves chemically using principles of molecular gratitude; the other being a "top-down" approach where nano-objects are constructed from larger entities without atomic-level control.

Transportation

Transportation is the movement of people and goods from one place to another. The term is derived from the portare ("to carry") and Latin trans ("across") . Industries which have the business of providing equipment, actual transport, transport of people or goods and services used in transport of goods or people make up a huge broad and important segment of most national economies, and are collectively referred to as transport industries.
The field of transport has several aspects: loosely they can be divided into a triad of infrastructure, vehicles, and operations. Infrastructure includes the transport networks (roads, railways, airways, waterways, canals, pipelines, etc.) that are used, as well as the nodes or terminals (such as airports, railway stations, bus stations and seaports). The vehicles generally traverse on the networks, such as automobiles, bicycles, buses, trains, aircrafts

Audio MIDI Interfaces

The Musical Instrument Digital Interface consents music to be recorded or produced by utilizing a data file containing multiple serially listed program status messages and matching note on and note off messages. In contrast, digital audio is usually compressed merely, exploiting a suitable data compression technique, and recorded. The audio content of such a digital recording may then be restored by decompressing the recorded data and converting that data by a digital-to-analog converter. The method and apparatus of the present invention selectively and alternatively couples portions of a compressed digital audio file and a MIDI file to a single digital signal processor which alternately decompresses the digital audio file and implements a MIDI synthesizer. Decompressed audio and MIDI synthesized music are then alternately attached to two separate buffers. The stuffing of these buffers are then additively mixed and coupled through a digital-to-analog converter to an audio output device to create an output having concurrent digital audio and MIDI synthesized music. A technique and equipment are unveiled for concurrently outputting digital audio and MIDI synthesized music utilizing a single digital signal processor.
