The Electronic Journal Of Combinatorics


Today, electronic devices are universally used in Computers, telecommunications and signal processing employing Integrated circuits with sometimes millions of transistors on a single chip. The early 1980s saw the rise of bass synthesizers, the most influential being the Roland TB-303, a bass synthesizer and sequencer released in late 1981 that later became a fixture in electronic dance music, particularly acid house. One of the first to use it was Charanjit Singh in 1982, though it wouldn't be popularized until Phuture's "Acid Tracks" in 1987. Music sequencers began being used around the mid 20th century, and Tomita's albums in mid-1970s being later examples. In 1978, Yellow Magic Orchestra were using computer-based technology in conjunction with a synthesiser to produce popular music, making their early use of the microprocessor-based Roland MC-8 Microcomposer sequencer.

Ambient dub was pioneered by King Tubby and other Jamaican sound artists, using DJ-inspired ambient electronics, complete with drop-outs, echo, equalization and psychedelic electronic effects. It featured layering techniques and incorporated elements of world music, deep basslines and harmonic sounds. Other notable artists within the genre include Dreadzone, Higher Intelligence Agency, The Orb, Ott, Loop Guru, Woob and Transglobal Underground. Laurie Spiegel developed the algorithmic musical composition software "Music Mouse" for Macintosh, Amiga, and Atari computers. Musical melodies were first generated by the computer CSIRAC in Australia in 1950. There were newspaper reports from America and England that computers may have played music earlier, but thorough research has debunked these stories as there is no evidence to support the newspaper reports .

Its broad and interdisciplinary scope covers the latest developments in all electronic engineering related fields including communication, biomedical, optical and device technologies. Electronics Letters also provides further insight into some of the latest developments through special features and interviews. In 1957, Kid Baltan and Tom Dissevelt released their debut album, Song Of The Second Moon, recorded at the Philips studio in the Netherlands. The public remained interested in the new sounds being created around the world, as can be deduced by the inclusion of Varèse's Poème électronique, which was played over four hundred loudspeakers at the Philips Pavilion of the 1958 Brussels World Fair. That same year, Mauricio Kagel, an Argentine composer, composed Transición II. The work was realized at the WDR studio in Cologne.

The subject covers a broad spectrum, from the design and development of an electronic system to assuring its proper function, service life and disposal. Electronic systems design is therefore the process of defining and developing complex electronic devices to satisfy specified requirements of the user. The first working point-contact transistor was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947. In April 1955, the IBM 608 was the first IBM product to use transistor circuits without any vacuum tubes and is believed to be the first all-transistorized calculator to be manufactured for the commercial market. Thomas J. Watson Jr. ordered all future IBM products to use transistors in their design. From that time on transistors were almost exclusively used for computer logic and peripherals.

Electroencephalogram signals are one such source to capture and study human emotions. In this Letter, a novel time-order representation based on the S-transform and convolutional neural network is proposed for the identification of human emotions. EEG signals are transformed into time-order representation based on the S-transform. This TOR is given as an input to CNN to automatically extract and classify the deep features. Emotional states of happiness, fear, sadness, and relax are classified with an accuracy of 94.58%. The superiority of the method is judged by evaluating four performance parameters and comparing it with existing state-of-the-art on the same dataset.

It replaces the current Eurosystem oversight approach for payment instruments and complements the Eurosystem’s oversight of payment systems. The Eurosystem will use the new framework to oversee companies enabling or supporting the use of payment cards, credit transfers, direct debits, e-money transfers and digital payment tokens, including electronic wallets. The PISA framework will also cover crypto-asset-related services, such as the acceptance of crypto-assets by merchants within a card payment scheme and the option to send, receive or pay with crypto-assets via an electronic wallet.

Resulted by suspended particles scattering and wavelength-dependent light attenuation, underwater images are always hazy and color-distorted. This paper is focused on a design of a high-voltage generator, which is proposed for a high-frequency irreversible electroporation (H-FIRE). Most HV sources used for cell electroporation are based on a controlled discharge of [...] Read more.

We caught up with them to find out more about the forthcoming show and why London has such a far-reaching influence in electronic music. They harness the energy and urgency of electronic music while largely doing away with emotion and invention. Operating, produced, or done by the action of electrons or other carriers in semiconductors, vacuum tubes, etc. Device has transistors or silicon chips which control and change the electric current passing through the device.

Cathode-ray tube, originally developed for displaying electrical waveforms on a screen for engineering measurements, evolved into the television picture tube. Such tubes operate by forming the electrons emitted from the cathode into a thin beam that impinges on a fluorescent screen at the end of the tube. Deflecting the electron beam causes patterns of light to be produced on the screen, creating the desired optical images.

Fire safety officials warned against using the wrong chargers for electronic equipment. They also want studies into the possible dangers from using electronic nicotine devices. A digitizing tablet is an electronic device that transmits the relative position of a stylus to software running on a host computer. Furthermore, electronic disease reporting from emergency departments was not in place at the time of this outbreak. It is one of a new class of electronic products variously called 'personal communicators' or 'personal digital assistants'. More examples You can use the device to scan the image and reproduce it on-screen in an electronic format.
