Die (integrated circuit)

A die in the context of integrated circuits is a small block of semiconducting material, on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die.

There are three commonly used plural forms: dice, dies, and die.

Die (manufacturing)

A die is a specialized tool used in manufacturing industries to cut or shape material mostly using a press. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology.

Die forming

Forming dies are typically made by tool and die makers and put into production after mounting into a press. The die is a metal block that is used for forming materials like sheet metal and plastic. For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers (called blister packs) for merchandise. Vacuum forming is considered a simple molding thermoforming process but uses the same principles as die forming. For the forming of sheet metal, such as automobile body parts, two parts may be used: one, called the punch, performs the stretching, bending, and/or blanking operation, while another part, called the die block, securely clamps the workpiece and provides similar stretching, bending, and/or blanking operation. The workpiece may pass through several stages using different tools or operations to obtain the final form. In the case of an automotive component there will usually be a shearing operation after the main forming is done and then additional crimping or rolling operations to ensure that all sharp edges are hidden and to add rigidity to the panel.

Aspö

Aspö is a small village on the Aspö Island in Väståboland, Finland. Until 2009 it belonged to the municipality of Korpo. Its Finnish-language name is Haapasaari, although this name is seldom used. The village is known for its white limestone church that has a red brick roof. The current church was built in 1955–1956; however, a church has existed in the place since the Middle Ages. The old church was destroyed in a storm in 1949.

History

The commercially seafaring Vikings landed on Aspö during the Viking period, 800 - 1050 AD. In the 13th century it also served as a harbour for traders. The trade route was laid between Tallinn, Estonia and Denmark. In the beginning of the 20th century only about 30 people lived on Aspö. Now there are only about 10 people.

During World War I until 1917, Aspö served as Russian naval military watchpost. In 1944 it served as the German navy base as the Germans were not allowed to anchor on Åland proper.

In the 1910s the Russians had a patrol station on the island. In the 1940s it was used as a harbour for submarines. On the contrary to the year of 1941, on 1944 the Finns allowed instead of Aland proper, the German navy to use only Aspö and Nötö as the naval base Rotbuche as there was a suspicion of the Tanne West operation which would have led to the German occupation of Aland Islands. The question became actual from 20 June to 27 June, when the president of the republic of Finland, mr. Risto Ryti and the foreign minister Joachim von Ribbentrop negotiated the terms continuing the war after the German arms export embargo in since April, 1944 due to the negotiations of peace with the Soviet union. A heavy naval detachment was sent via Utö towards Aspö.

Asp (fish)

The asp (Aspius aspius) is a European freshwater fish of the Cyprinid family. It is protected by the Bern Convention of endangered species and habitats (Appendix III). Asps are also on the IUCN Red List of endangered species.

Normally, asps are between 10 and 80 cm in length, with some reaching 120 cm, and weighing up to 12 kg. They inhabit lakes and lower reaches of rivers and estuaries. In spring, in April–June, asps migrate from lakes to streams for spawning. Spawning is triggered by the rise in temperature and usually starts at 6°C. The eggs attach to rocks, gravel, and water plants. After around two weeks, they hatch and the fry drift downstream to calmer waters.

Asps can be found in Estonia, Germany, Norway, Sweden, Finland, the Czech Republic, Poland, Ukraine, Romania, Russia, Switzerland, Slovenia, the Netherlands, and Belgium. In Switzerland, asps have migrated through the Rhine-Main-Danube Canal, as in Croatia, Austria, Hungary and Slovakia. In the eastern regions of Europe, it is a common species in flowing waters, and popular for fly and other types of fishing.

Archive file

An archive file is a file that is composed of one or more computer files along with metadata. Archive files are used to collect multiple data files together into a single file for easier portability and storage, or simply to compress files to use less storage space. Archive files often store directory structures, error detection and correction information, arbitrary comments, and sometimes use built-in encryption.

Applications

Archive files are particularly useful in that they store file system data and metadata within the contents of a particular file, and thus can be stored on systems or sent over channels that do not support the file system in question, only file contents – examples include sending a directory structure over email.

Beyond archival purposes, archive files are frequently used for packaging software for distribution, as software contents are often naturally spread across several files; the archive is then known as a package. While the archival file format is the same, there are additional conventions about contents, such as requiring a manifest file, and the resulting format is known as a package format. Examples include deb for Debian, JAR for Java, and APK for Android.
