In the ListFish directory, "frequency" denotes --in number of days per week or month-- how often a publication is distributed. This number cannot always be precise, especially with discussion lists, but it should give you a good idea of what to expect in your in-box. Very often, discussion lists are listed with a frequency of "7 days" due to the spontaneous nature of the list: in other words, a post could be distributed to the list at any time. Additionally, and again in the case of discussion lists, "7 days" may mean that multiple posts may be distributed on any given day; some particularly active lists, for example, might receive 50 or more posts a day (look for the word "active" in the list's description). If you find that you are receiving more email from a list than you can keep up with, you may prefer to subscribe to the digest version (if available), rather than post-by-post.

When talking about domes, frequency refers to the number of pieces that each edge of the base figure is divided into in the process of triangulating its sides. For instance, we might start with a base figure of an icosahedron and divide each edge of each triangular face into 3 equal lengths. Those new points are connected to divide the original triangle into 9 smaller triangles. Since the original edges were divided into 3 parts, we call this a 3-frequency dome. The frequency is commonly abbreviated as "f", so a 2-frequency dome is called 2f, 3-frequency is 3f, and so forth. You can find more about frequency at the Synergetics Home Page section on geodesic dome geometry.

Repeating occurrence.

the number of sound vibrations per second; frequency determines pitch which is the highness or lowness or a sound; the faster an object vibrates, the sound it emits will have a higher pitch, the slower an object vibrates, the sound it emits will have a lower pitch. Therefore, whatever causes an object to vibrate faster or slower, will change the pitch of the sound it makes. For example, a guitar string which is thicker, vibrates slower and will have a lower pitch. A guitar string which is thin will vibrate faster and have a higher pitch. The other way to make a guitar string vibrate slower or faster is by 'shortening' or 'lengthening' it. This is easily done by pressing your finger onto the string which is, in effect, shortening it. A shorter string vibrates faster and will have a higher pitch. Letting go of the string is, in effect, 'lengthening' the string. A 'longer' string will vibrate slower and have a lower pitch.

the frequent need to pass urine, often just small amounts. Gleason score scale that shows how aggressive a cancer is by analysing the type of cells present in a sample. It is important to know this because the score affects the treatment choices. The scale goes from 2-10, with 2-6 being termed non-aggressive, 7 moderately aggressive and 8-10 aggressive. hesitancy the need to wait a moment or two before the flow of urine starts, even when the bladder is full.

Annually since 1951 (except 1954); reported data are for activity taking place over the prior calendar year. Data collection begins in January following the end of the survey year. New samples are chosen approximately every 5 years and are updated quarterly. Use of the latest sample began in the 1999 survey year.

Number of coupon installments paid annually. Zero-coupon bonds, which pay no coupons, have frequencies of zero. Corporate bonds typically pay interest twice a year (semi-annually). CMOs pay interest either monthly or quarterly, while mortgage pools pay once a month. Eurobonds often pay annually.

In a car audio context, this can refer to two things. The first is the most common usage: radio frequency. Radio stations are each accessed via tuning into their frequency band. The second meaning is sound frequency. High sounds are high frequency (which are ideally played via power-efficient tweeters), with lower sound sent via lower frequencies, which take more power to play and are if at all possible played through woofers. Equalisation (EQ) involves balancing the volumes of these different frequency bands to get the required playback.

all radio control gear works on frequencies. Best explained here.

(see "Band")

The band on which a unit is to operate its radio communications.

In Windows Media Player, the number, such as 88.5 or 101.7, used to locate a radio station. genre In Windows Media Technologies, the type of music, such as rock or classical, played by a radio station. header A part of the file structure that contains information required by an application to decompress and render the content. The header in a protected file also contains information required to get a license.

The assigned channel in which a TV or radio station can transmit a singal.

Refers to the type of wireless band that a wireless network device operates in. All devices that emit radio waves (i.e. microwaves, telephones, wireless networking products) work in certain frequency bands. In the wireless networking world, the most commonly used frequencies are 2.4GHz and 5GHz. 802.11g and 802.11b wireless network devices operate in the 2.4GHz band, 802.11a devices work in the 5GHz band.

Used by Fuller to specify length and size in general. The intention is to employ a more precisely descriptive term for both geometric systems and events in nature, than is provided by specific units of measurement. Fuller points out that frequency never relates to the quantity "one," for it necessarily involves a plurality of experiences.
