DECT operates in the 1880-1900 MHz band and defines ten channels from 1881.792 MHz to 1897.344 MHz with a band gap of 1728 kHz. Each base station frame provides 12 duplex speech channel with each time slot occupying any of channel. DECT operates in multicarrier/TDMA/TDD structure. DECT also provides Frequency-hopping spread spectrum over TDMA/TDD structure. If frequency hopping is avoided then each base station can provide up to 120 channels in the DECT spectrum before frequency reuse. Each time slot can be assigned to a different channel in order to take advantage of frequency hopping and avoid interference from other users in asynchronous fashion.

Epcot
Epcot (Experimental Prototype Community of Tomorrow) is part of Disney World in Orlando, Florida. It is split into two parts: Future World and the World Showcase. Future World has many rides and shows about technology, including space travel and how people interact with nature. The World Showcase is split into sections representing eleven countries, sharing the culture of each country there. The symbol of the park is Spaceship Earth, a huge building that looks like a golf ball and has a ride inside.
Walt Disney's original plan for Epcot was for it to be a neighborhood for people to live in with many modern machines aiding their lives. It was going to be called the Experimental Prototype Community of Tomorrow, which is where the name EPCOT comes from. Disney died before he could start his plan, and later the new owners of the Walt Disney Company changed the plans into a theme park.
Future World is in the front of the park. Its theme is technology. Spaceship Earth is near the entrance. The ride inside of it is a journey through human methods of communication, from ancient cave paintings up to the Internet and beyond.
Past Spaceship Earth are many rides and attractions about technology. Innovations is two buildings full of games and shows that use new inventions for making life easier.
There are also two buildings with similar themes: Living with the Land and the Living Seas. Living with the Land has a boat ride inside about the history of farming. It also has a food court that serves food made from the plants grown there. The Living Seas is an aquarium with a ride featuring characters from the movie "Finding Nemo". In the aquarium are many kinds of sea creatures, including dolphins, sharks and manatees.
Other rides in Future Word include Test Track, which is about how cars are tested for safety before being sold, and Mission: Space, which is a pretend trip to the planet Mars. Ellen's Energy Adventure stars Ellen DeGeneres and Bill Nye the Science Guy and is about the history of energy, from the time of the dinosaurs up to today's solar power and wind power. Imagination! is about the human imagination.
The World Showcase is split into areas, called pavilions, representing eleven countries. They are in a circle around a big lake called the World Showcase Lagoon. In clockwise order, the pavilions are:
Each pavilion is built to look like the country it represents. They all have restaurants that serve food from their home country. Many of the people working there were born in the country their pavilion represents.
The Mexico pavilion has a ride. The Norway pavilion does not have a ride yet, but they are planning to add one soon. The China, France and Canada pavilions have movies about their countries. The America pavilion has a stage show with audio-animatronic figures about the history of the United States.
The Imagination! Pavilion has the Following Attractions:
Aleph null
Aleph null (also aleph naught or aleph 0) is the smallest infinite number. It is the cardinality (size) of the set of natural numbers (there are aleph null natural numbers). Georg Cantor invented and named the concept. The symbol for aleph null is formula_1
It is the first infinite number in a series of infinite cardinal numbers. In fact, it is the size of any set which can be matched with the natural numbers. The set of algebraic numbers, for example, has cardinality formula_1.
Aleph null is followed by aleph one, an infinite number represented by the symbol formula_3.

Eyjafjallajökull
Eyjafjallajökull (pronounce: "Ei-ya-fyat-LA-yer-kitle) is a volcano in Iceland. The name means "island-mountains glacier".
The south end of the mountain was once part of the coastline of the Atlantic ocean. The sea gradually moved about 5km south. Now there are beautiful steep cliffs and waterfalls.
The volcano erupted several times in 1821 and 1822. Some cattle and sheep died, presumably because of fluoride poisoning.
At Christmas 2009 the volcano started to show signs of being active again. On 27 March 2010 it started to erupt. On 14 April 2010 Eyjafjallajökull started to erupt heavily from the top crater in the bottom left of the glacier. This made meltwater floods to rush down the nearby rivers. Many people had to be evacuated. Volcanic ash was thrown several kilometres into the atmosphere. The dust blow over northwest Europe on the 15th and 16th April 2010. It became very dangerous for aeroplanes to fly and so all commercial flights were stopped in most parts of northern Europe. This caused chaos for travellers, many of whom were trying to return home after their Easter vacation. The chaos continued for many days.
The volcano was featured in 2013's The Secret Life of Walter Mitty in a scene where Walter had to run from an eruption after pursuing Sean O' Connell to Iceland.
Anonymous function
In computer science and mathematics, an anonymous function is a function with no name. Usually, a function is written like: formula_1. It can be written anonymously as formula_2. Anonymous functions exist in most functional programming languages and most other programming languages where functions are values.
Each of these examples show a nameless function that multiplies two numbers.

The function can also be written in point-free (tacit) style:

Italian conquest of British Somali Coast Protectorate
The Italian conquest of the British Somali Coast Protectorate was an Italian campaign during World War II against the British Empire. It was the only Italian victory against the Allies that was won without help from Germany.
When Italy declared war in May 1940, the Italian troops were not prepared for a prolonged war in Eastern Africa. As a consequence, Mussolini ordered only some limited aggressive actions to capture territory along the borders of Kenya, Egypt and Sudan. Some skirmishes happened even in French Somalia, with an invasion of the western half of Djibouti.
