The reuse distance, D is calculated as where R is the cell radius and N is the number of cells per cluster. Cells may vary in radius from 1 to 30 km. The boundaries of the cells can also overlap between adjacent cells and large cells can be divided into smaller cells. The frequency reuse factor is the rate at which the same frequency can be used in the network. It is 1/K (or K according to some books) where K is the number of cells which cannot use the same frequencies for transmission. Common values for the frequency reuse factor are 1/3, 1/4, 1/7, 1/9 and 1/12 (or 3, 4, 7, 9 and 12 depending on notation).

In this manner, both along-line and cross-line gradients can be calculated. In traditional mineral exploration and archaeological work, grid pegs placed by theodolite and tape measure were used to define the survey area. Some UXO surveys used ropes to define the lanes. Airborne surveys used radio triangulation beacons, such as Siledus. Non-magnetic electronic hipchain triggers were developed to trigger magnetometers. They used rotary shaft encoders to measure distance along disposable cotton reels. Modern explorers use a range of low-magnetic signature GPS units, including Real-Time Kinematic GPS. Magnetic surveys can suffer from noise coming from a range of sources.
Kickstarter.comkick starterKickstarter campaign
On August 30, 2014, the "Coolest Cooler", an icebox created by Ryan Grepper, became the most funded Kickstarter project in history, with US$13.28 million in funding, breaking the record previously held by the Pebble smart watch. From 2012 to 2013, Wharton professor Ethan Mollick and Jeanne Pi conducted research into what contributes to a project's success or failure on Kickstarter.
Motoactv (styled MOTOACTV) was a smartwatch sold by Motorola which contains a number of hardware features and software applications tailored to fitness training. The watch contains apps for monitoring athletic activity using a built-in accelerometer to measure strides and GPS to measure distance. It can also be synced with a Speed/Cadence Bike Sensor or foot pod via ANT+ technology. The watch can communicate with external devices over Bluetooth 4.0 such as pulse sensor and Bluetooth stereo headphones for music. In addition, there is a DJ mode that will custom tailor the music dynamically to the workout. It was announced on October 18, 2011, and released to the US market on November 6, 2011.
On March 31, 1854, Commodore Matthew Perry and the "Black Ships" of the United States Navy forced the opening of Japan to the outside world with the Convention of Kanagawa. Subsequent similar treaties with Western countries in the Bakumatsu period brought economic and political crises. The resignation of the shōgun led to the Boshin War and the establishment of a centralized state nominally unified under the Emperor (the Meiji Restoration).
cadenceCycling cadencepedalling cadence
In cycling, cadence (or pedalling rate) is the number of revolutions of the crank per minute; this is the rate at which a cyclist is pedalling/turning the pedals. Cadence is directly proportional to wheel speed, but is a distinct measurement and changes with gearing—which determines the ratio of crank rpm to wheel rpm.

The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as cycles per one second. It is named after Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (10 3 Hz, kHz), megahertz (10 6 Hz, MHz), gigahertz (10 9 Hz, GHz), terahertz (10 12 Hz, THz), petahertz (10 15 Hz, PHz), exahertz (10 18 Hz, EHz), and zettahertz (10 21 Hz, ZHz).
triathletetriathlonsOlympic Distance Triathlon
This program shocked many that watched and was the introduction of the sport to the general public. Some fans of traditional sports strongly criticised this new practice as seven of the entrants were hospitalised due to the swim, as the temperature of the Mediterranean was only 14°C. Despite this criticism IMG's plan succeeded and throughout the 1980s. The Nice triathlon was, alongside Hawaii, one of the two important Long Distance races each year for both prize money and media attention.
Sony CorporationSony ElectronicsSony Corp.
In April 2012, Sony announced that it would reduce its workforce by 10,000 (6% of its employee base) as part of CEO Hirai's effort to get the company back into the black. This came after a loss of 520 billion yen (roughly US$6.36 billion) for fiscal 2012, the worst since the company was founded. Accumulation loss for the past four years was 919.32 billion-yen. Sony planned to increase its marketing expenses by 30% in 2012. 1,000 of the jobs cut come from the company's mobile phone unit's workforce. 700 jobs will be cut in the 2012–2013 fiscal year and the remaining 300 in the following fiscal year.
Address generation unit (AGU), sometimes also called address computation unit (ACU), is an execution unit inside the CPU that calculates addresses used by the CPU to access main memory. By having address calculations handled by separate circuitry that operates in parallel with the rest of the CPU, the number of CPU cycles required for executing various machine instructions can be reduced, bringing performance improvements. While performing various operations, CPUs need to calculate memory addresses required for fetching data from the memory; for example, in-memory positions of array elements must be calculated before the CPU can fetch the data from actual memory locations.
RAMmemoryrandom access memory
Toshiba's Toscal BC-1411 electronic calculator, which was introduced in 1965, used a form of capacitive bipolar DRAM, storing 180-bit data on discrete memory cells, consisting of germanium bipolar transistors and capacitors. While it offered improved performance over magnetic-core memory, bipolar DRAM could not compete with the lower price of the then dominant magnetic-core memory. MOS technology is the basis for modern DRAM. In 1966, Dr. Robert H. Dennard at the IBM Thomas J. Watson Research Center was working on MOS memory.
Garmin registered the name "Forerunner" with the United States Patent and Trademark Office in August 2001 but released the first watches — the 101, 201, and 301 — in 2003. In 2006, the improved 205 and 305 appeared. These models are smaller than the first generation and feature a more sensitive SiRFstarIII GPS receiver chip. In late 2007, the Forerunner 50 was introduced. As opposed to GPS, this model paired with a foot pod to measure displacement. The Forerunner 50 also came packaged with a USB stick that allowed training data to be transferred wirelessly to one's pc. This feature has since become a staple of Garmin's more full-featured sport watches.

This decrease in pressure was further demonstrated by carrying a half-full balloon up a mountain and watching it gradually expand, then contract upon descent. In 1650, German scientist Otto von Guericke constructed the first vacuum pump: a device that would further refute the principle of horror vacui. He correctly noted that the atmosphere of the Earth surrounds the planet like a shell, with the density gradually declining with altitude. He concluded that there must be a vacuum between the Earth and the Moon. Back in the 15th century, German theologian Nicolaus Cusanus speculated that the Universe lacked a center and a circumference.
A pressure of 1 atm can also be stated as: The ata unit is used in place of atm to indicate that the pressure shown is the total ambient pressure, compared to vacuum, of the system being calculated or measured. For example, for underwater pressures, a pressure of 3.1 ata would mean that the 1 atm of the air above water is included in this value and the pressure due to water would total 2.1 atm. ≡ 101325 pascals (Pa). ≡ 1.01325 bar. ≈ 1.033 kgf/cm². ≈ 1.033 technical atmosphere. ≈ 10.33 m H 2 O, 4 °C. ≈ 760 mmHg, 0 °C, subject to revision as more precise measurements of mercury’s density become available. ≡ 760 torr (Torr).

Three categories of peripheral devices exist based on their relationship with the computer: Many modern electronic devices, such as internet capable digital watches, keyboards, and tablet computers, have interfaces that allow them to be used as computer peripheral devices. 1) an input device sends data or instructions to the computer, such as a mouse, keyboard, graphics tablet, image scanner, barcode reader, game controller, light pen, light gun, microphone, digital camera, webcam, dance pad, and read-only memory). 2) an output device provides output from the computer, such as a computer monitor, projector, printer, headphones and computer speaker); and. 3) an input/output device performs both
Accessories that are worn may include jackets, boots and shoes, cravats, ties, hats, bonnets, belts and suspenders, gloves, muffs, necklaces, bracelets, watches, sashes, shawls, scarves, lanyards, socks, pins, piercings, rings, and stockings. The type of accessory that an individual chooses to wear or carry to complement their outfit can be determined by several factors including the specific context of where the individual is going. For example, if an individual is going to work their choice of accessory would differ to one who is going out to drinks or dinner thus depending on work or play different accessories would be chosen.
Backlights are used in small displays to increase readability in low light conditions such as in wristwatches, and are used in smart phones, computer displays and LCD televisions to produce light in a manner similar to a CRT display. A review of some early backlighting schemes for LCDs is given in a report Engineering and Technology History by Peter J. Wild. Simple types of LCDs such as in pocket calculators are built without an internal light source, requiring external light sources to convey the display image to the user. Most LCD screens, however, are built with an internal light source. Such screens consist of several layers. The backlight is usually the first layer from the back.
TimexTimex CorporationWaterbury Clock Company
The company continued to focus on high-priced watch models and eventually fell into receivership, discontinuing business in July 1912. Robert H. Ingersoll & Bro. bought the Waterbury plant and began manufacturing Ingersoll Watches there in 1914. World War I brought new demands for timepiece design; artillery gunners, for example, needed an easy way to calculate and read time while still being able to work the guns. The Waterbury Clock Company met this need by modifying their small Ingersoll ladies' Midget pocket watch.
