Here the absent sitter makes a `` date '' with a communicator ( someone close to him who is deceased ), asking him to `` come in '' at a certain hour, when a channel will be open for him.

These are used where the vessel is permanently or semi-permanently sited, for example in the case of lightvessels or channel marker buoys.

When a vessel is in a narrow channel or on a lee shore so that there is no room to tack the vessel in a conventional manner an anchor attached to the lee quarter may be dropped from the lee bow.

Although the hardware is limited to four separate sound channels, software such as OctaMED uses software mixing to allow eight or more virtual channels, and it was possible for software to mix two hardware channels to achieve a single 14-bit resolution channel by playing with the volumes of the channels in such a way that one of the source channels contributes the most significant bits and the other the least.

Each channel is spaced from the adjacent ones by 8. 33 kHz in Europe, 25 kHz elsewhere.

In a 2D image element, which stores a color for each pixel, additional data is stored in the alpha channel with a value between 0 and 1.

If an alpha channel is used in an image, it is common to also multiply the color by the alpha value, to save on additional multiplications during compositing.

With the existence of an alpha channel, it is possible to express compositing image operations, using a compositing algebra.

and resulting alpha channel value is

For some applications, a single alpha channel is not sufficient: a stained-glass window, for instance, requires a separate transparency channel for each RGB channel to model the red transparency, green transparency, and blue transparency.

Flupirtine is a centrally acting K + channel opener with weak NMDA antagonist properties.

Some Anglicans accept that anointing of the sick has a sacramental character and is therefore a channel of God's grace, seeing it as an " outward and visible sign of an inward and spiritual grace " which is the definition of a sacrament.

The Accelerated Graphics Port ( often shortened to AGP ) is a high-speed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics.

A channel actually consists of two signals: the picture information is transmitted using amplitude modulation on one frequency, and the sound is transmitted with frequency modulation at a frequency at a fixed offset ( typically 4. 5 to 6 MHz ) from the picture signal.

In practice a technique called vestigial sideband is used to reduce the channel spacing, which would be at least twice the video bandwidth if pure AM was used.

Signal reception is invariably done via a superheterodyne receiver: the first stage is a tuner which selects a television channel and frequency-shifts it to a fixed intermediate frequency ( IF ).

Cytochrome c is also released from mitochondria due to formation of a channel, the mitochondrial apoptosis-induced channel ( MAC ), in the outer mitochondrial membrane, and serves a regulatory function as it precedes morphological change associated with apoptosis.

Lundy is the largest island in the Bristol Channel, lying off the coast of Devon, England, approximately one third of the distance across the channel between England and Wales.

The channel is approximately across at its narrowest point between Angoche, Mozambique, and Tambohorano, Madagascar.

Part of the Atlantic Intracoastal Waterway, the canal is approximately 7 miles, or 11. 3 km long of which most follow tidal rivers that are widened and deepened into a ship channel.

The current required to form the conductive channel is around 100µA / 100nm2 and the breakdown occurs in approximately 100µs or less.

The channel is 5. 6 kilometers across and approximately 106. 7 meters deep.

By 2001, Disney Channel was available to approximately 70 million cable and satellite subscribers, largely consisting of those who already received the channel via a basic tier as well at the remnants of its pay subscriber base.

Here, the narrow channel of Carnley Harbour ( the Adams Straits on some maps ) separates the main island from the roughly triangular Adams Island ( area approximately ), which is even more mountainous, reaching a height of at Mount Dick.

He showed that speech features are usually spread over a wide frequency range, and developed the articulation index to approximately quantify the quality of a speech channel.

Rate – distortion theory is a major branch of information theory which provides the theoretical foundations for lossy data compression ; it addresses the problem of determining the minimal number of bits per symbol, as measured by the rate R, that should be communicated over a channel, so that the source ( input signal ) can be approximately reconstructed at the receiver ( output signal ) without exceeding a given distortion D.

* In 1999, the Film4 channel, frustrated by the lack of any extended version of the film available in the UK ( only the low quality 1981 censored version was still in print ), released their own cut of Caligula, running approximately 143 minutes ( the missing 13 minutes can be mostly attributed to the PAL overspeeding and time compression ).

* On August 2, 1957, the world record for high-band ( channels 7 – 13 ) sporadic E television DX was extended to approximately with the reception of the YVLV channel 9 relay from Maracaibo, Venezuela, by Bobby Grimes in Little Rock, Arkansas.

This mudflow flowed down the valley of the Lagunillas River for approximately, spilling out of the river channel and killing much of the local population.

It is a long thin channel approximately 27 kilometres long and averaging 3 kilometers wide ( 1 km at its narrowest ).

Early decoders seemingly support only 700 channels approximately in their channel listing, as Sky has announced it is halting SD channels ' launch applications, with over 100 awaiting launch, over 600 existing channels, and an average closure rate of 1 per week.

At approximately the same time, Granada run archive channel Granada Plus closed to make way for ITV3.

The channel of the Hudson as it passes through the harbor is called the Anchorage Channel and is approximately 50 feet deep in the midpoint of the harbor.

Therefore, people's maximum performance on one-dimensional absolute judgement can be characterized as an information channel capacity with approximately 2 to 3 bits of information, which corresponds to the ability to distinguish between 4 and 8 alternatives.

The maximum capacity of Ardnacrusha is approximately 400 m < sup > 3 </ sup >/ s, 40 times that which is required to flow down the natural channel ( although the power station does not necessarily run at this capacity at all times ).

The entrance of the bay is approximately wide, with a narrow navigable channel.

Portage la Prairie is located approximately west of Winnipeg, along the Trans Canada Highway ( located exactly between the provincial borders of Saskatchewan and Ontario ), and sits on the Assiniboine River, which flooded the town persistently until a diversion channel north to Lake Manitoba ( the Assiniboine River Floodway ) was built to divert the flood waters.

Most of the Bay is shallow ; however, there is a deep water channel approximately in mid bay, which allows access to Sacramento, Stockton, Benicia, Martinez, and other smaller Delta ports.

* sodium ion channel: Na < sup >+</ sup > is approximately + 55mV

* potassium channel: K < sup >+</ sup > is approximately − 95mV

* chloride channel: Cl < sup >−</ sup > is approximately − 90mV
