Profile diagram. In Unified Modeling Language
in the field of software engineering,
a profile diagram
operates at the metamodel level to show stereotypes as classes with the «stereotype» stereotype, and profiles as packages with the «profile» stereotype. The extension relation (solid line with closed, filled arrowhead) indicates what metamodel element a given stereotype is extending.

History
The profile diagram did not exist in UML 1. 
Other diagrams had been used to display this issue.
It was introduced with UML 2 to display the usage of profiles.

Kunstgraben. A Kunstgraben is a type of man-made water channel that was once used by mines to drive the water wheels needed for power, mine drainage and a host of other purposes. The term is German (plural: Kunstgräben). Similar ditches supplying water mills in England are called leats.

Background 
Until the invention of the steam engine, water power was the main source of energy utilised by the various mechanical engines employed in the mining industry, such as water wheels, reversible water wheels, water-column engines or water turbines.

To enable mine workings to be driven ever deeper, more and more power was needed. The water available in the vicinity of the pits was insufficient for that purpose and springs frequently dried up as a result of be diverted for use in the mines. As a result, the water needed for the mine workings sometimes had to be transported over long distances.

Usage 
The aim was to have the greatest possible height difference at the site of the water power engine. This difference is known as the height of impact (Aufschlaghöhe). To achieve this the Kunstgräben were laid with only a very slight gradient, so that they resembled contours in the terrain and followed all the twists and turns of the valleys. In order to overcome natural obstacles Kunstgräben were frequently led along the bottom of tunnels in so-called Röschen or, more rarely, over aqueducts; the best-known Kunstgraben aqueducts being the Altväter Bridge near Halsbrücke and the Sperberhai Dyke in the Harz Mountains.

Typically a Kunstgraben started at a weir or divert (Wasserteiler) and ran along Röschen and via water storage ponds or Kunstteiche to the pit. The water power engine usually had a headrace and a tailrace (Aufschlagrösche and Abzugsrösche). A footpath was laid parallel to the Kunstgraben that acted as an access route for the ditch overseer (Grabensteiger), whenever he went to the weir to adjust the paddles. These paths are frequently used as walking trails today, where they have survived.

The Kunstgräben were often covered by rough boards (Schwarten). These acted, on the one hand, to keep the ditches clear and protect them from becoming overgrown and, on the other hand, to protect the ditches from destruction by cattle. It also helped to defend the owners of the ditches from the claims of neighbouring landowners, who had otherwise to be compensated for the loss of income and land resulting from the construction of Kunstgräben and who often brought claims as a result of allegedly drowned livestock and game.

Oldershaw O-2. The Oldershaw O-2, officially registered as the Oldershaw Jana-Linn O-2, is an American high-wing, single seat, V-tailed glider that was designed and built by Vernon Oldershaw.

Design and development
The O-2 was designed by Oldershaw to compete with Dick Johnson's Ross-Johnson RJ-5.

The O-2 is constructed of wood. Its  span wing employs a NACA 63 (3)-618 airfoil at the wing root, with a NACA 63 (2)-615 at the wing tip. The wing is equipped with dive brakes. The landing gear is a retractable monowheel.

Only one O-2 was built.

Operational history
The O-2 first flew in 1961 and was flown by Oldershaw in the 1962 and 1962 US Nationals. The aircraft has made a number of flights in excess of , including one of . Oldershaw later sold the aircraft to Don Gaede of Torrance, California and it was reportedly still being actively flown in the 1980s. Gaede remodeled the cockpit and introduced a new nose shape. The O-2 was later donated to the US Southwest Soaring Museum, where it is on display.

Blériot 195. The Blériot 195 was a French monoplane mail-carrier designed and built by Blériot Aéronautique, the one aircraft built was modified a number of times but failed to enter production.

Design and development
The Blériot 195 was a large low-wing cantilever monoplane designed for use on mail flights across the North Atlantic. It was powered by four  Hispano-Suiza 6Mb inline piston engines, which were mounted in tandem pairs above the wing on a complex of struts. Designated the 195/2 landplane, it first flew on 9 March 1929. By the end of 1929, it had been re-designated the 195/3 and test flown with twin floats. It was re-designated again as the 195/4 in early 1930, when it was fitted with  Gnome-Rhone Titan engines. It was put forward to meet a requirement for a seaplane to operate a mail service between Marseilles and Algiers, but in the end none of the designs submitted were accepted and the 195 was placed into storage.

In April 1931 it was brought out of storage and modified to be a landplane and designated the 195/6; it was then tested by Air Union as a cargo aircraft. It did not gain a certificate of airworthiness as a cargo carrier and was withdrawn from use.

USCGC Nettle. USCGC Nettle (WAK-169) was a United States Coast Guard Design 381 coastal freighter acquired from the United States Army and was designated as USA FS-396 during World War II army operations. She was transferred to the United States Coast Guard in 1947, and used for servicing aids to navigation and providing logistics support for U.S. Coast Guard manned LORAN stations in the Pacific Ocean.

History

U.S. Army cargo service
FS-396 was constructed by Ingalls Shipbuilding Corp. at their shipyards at Decatur, Alabama for the U.S. Army Transportation Corps and commissioned 18 January 1945. She was manned by the U.S. Coast Guard for a period of one year and was used as a cargo ship to carry supplies to Kwajalein Atoll until being decommissioned on 18 January 1946.

U.S. Coast Guard service

FS-396 was transferred to the U.S. Coast Guard and on 1 October 1947 was recommissioned as USCGC Nettle (WAK-169) after being refitted for use as an aids to navigation tender. From 1947 to 1952, Nettle hauled supplies and equipment to Kwajalein in the Marshall Islands. Nettle was home-ported at Guam in 1952 and provided logistical support for LORAN stations at Ulithi, Saipan, Cocos, Kwajelein, and Kwadak Island as well as servicing aids to navigation at Tinian and Rota in the Mariana Islands.

The home port for Nettle was changed to Naval Station Sangley Point, Cavite, Philippines in August 1953 and she provided logistical support for LORAN stations at Bataan, Batanes, Naulo Point, Zambales, Talumpulan, Busuanga, Tarumpitao Point, Palawan, and Panay.

While underway from Bataan on 1 September 1958, Nettle spotted and assisted the capsized junk Low Kow Wong How and rescued two of the crew. She was able to right the junk with her deck crane and pump it out, then continued her mission to deliver supplies to Naulo Point. During another search and rescue case on 2 August 1962, she searched the waters in the vicinity of Caballo Island for 29 hours looking for the missing crew of a downed U.S. Navy P5M seaplane with 13 persons aboard; there were no survivors found. During May 1966, Nettle delivered construction materials from Bangkok for a new LORAN station to be located at Con Son Island. Nettle was transferred to Philippine Coast Guard, 9 January 1968 as BRP Limasawa (AE-79).

European Space Weather portal. The European Space Weather Portal (ESWeP) results from the COST (European Cooperation in Science and Technology) action 724 (Developing the basis for monitoring, modelling and predicting Space Weather).  ESWeP is a website providing a centralized access point to the space weather community to share their knowledge and results.  The website is hosted and maintained at the Belgian Institute for Space Aeronomy.  Its development will be continued in the framework of the COST ES0803 action (Developing space weather products and services in Europe).

On ESWeP, a section is devoted to education and outreach.  Children as young as five years old are invited to get involved in some of these activities.  For example, artworks illustrating space weather made by primary school children from several countries are presented on the website.

Models
The portal provides a platform to run local and remote models and access their results both in graphical and numerical forms.  Models hosted at ESWeP:
 Geomagnetic cutoff calculations (K. Kudela (IEP/SAV) & M. Storini (IFSI/CNR), COST724)
 SOLPENCO (A. Aran, B. Sanahuja and D. Lario, University of Barcelona, COST724)
 Exospheric solar wind model (H. Lamy and V. Pierrard, BISA, COST724)
 Plasmapause location (V. Pierrard, BISA, COST724)
 Magnetocosmics cutoffs (L. Desorgher, University of Bern, COST724)
 Magnetocosmics trajectories (L. Desorgher, University of Bern, COST724)

Space weather document repository
Space weather research and services can only be organized efficiently with reference documentation.  The FP7 SOTERIA project identified the need to have a repository where space weather professionals can upload and share their technical documents, reference documents, standards, or research papers.

The "Space Weather Document Repository", which is an online tool to disseminate reference documents (papers, reports, etc.) that are space weather-related, was developed by ESWeP in collaboration with SOTERIA.

PFM Group. PFM Group is an Italian multinational company in the packaging and weighing machinery industry, producing Flow Wrap and Form Fill Seal machines, automatic packaging lines and Multihead weighers employed in the food and non-food industries.

Arrangement of the company 
PFM Group is made up of nine companies: the Italian parent company, PFM Packaging Machinery, which works alongside the UK PFM LTD, North American PFM Corporation, and German PFM Germany companies. BG Pack SPA, which is based in Bergamo, specialising in the manufacture of special packaging machines for recloseable packs. MBP, based in Mantua, specialise in the production of multi-head weighers and vertical packaging machines thereby completing the range offered by PFM. Last in order of acquisition is SPS Italiana Pack Systems, which has come back into the hands of those who founded the company after exchanging ownership a number of times; this company from Novara manufacture automatic handling and packaging machines for baked goods and biscuits, chocolate bars and wafers. In 2006 PFmeccanica was founded to form a new production centre for mechanical components. In November 2007 PFM Russia was founded, the new commercial and logistic base for the Eastern European markets.

History 
In 1964 Italianapack, which produces horizontal flow packaging machines, is founded by Fioravanti Pietro in Vicenza. Italiana pack is then sold, in 1972, to the American FMC Corporation. After a crisis, the industry starts the production of forced hot air rotary ovens for many years, until 1982 when PFM starts reducing the production of ovens while the flow pack catches on. 1984 sees the arrival of PFM in the United States, thanks to a foreign sales increase for the Europe area in the preceding year.In 2001 PFM acquires the majority share of the company BG Pack, with the aim to complete its range of vertical and horizontal flow-pack machines for ergonomic and easy-opening packaging, with a particular focus in cheese packaging. The next year PFM obtains the UNI EN ISO 9001-2000 (Vision 2000) certification for the Central Italian headquarters and also acquires the majority share of the company MBP, producers of multi-head and vertical packaging machines, entering the weighing market.
In 2003 PFM buy 100% of SPS Packaging System, which is the formerly named Italianapack, sold in 1972 and now rejoining the group.

Products 
PFM designs, builds and markets around 40 models of flow-wrapping and vertical form-fill-seal machines together with various automatic feed systems and multihead weighers. Machines are produced for various sectors of the food industry from dairy, which is its most significant sector, to meat, confectionery, bakery goods, fruit and vegetables as well as non-food industries such as pharmaceuticals and cosmetics.
