Business & Information Systems Engineering. Business & Information Systems Engineering is a bimonthly peer-reviewed academic journal covering research on the design and utilization of information systems.

History
The journal is the English language successor of wirtschaftsinformatik, which was the flagship journal of the German-language information systems community for more than 50 years. The German journal Elektronische Datenverarbeitung, published since 1959, was renamed Angewandte Informatik in 1971 and again in Wirtschaftsinformatik in 1989, with the first issue published in 1990. To expand its reach in Europe and internationally, and to better reach its international scientific community, Wirtschaftsinformatik was published in a cover-to-cover English translation under the title Business & Information Systems Engineering since issue 1/2009. The strategic decision to better address the international community led to the termination of the German version with issue 6/2014; from issue 1/2015 onwards only the English journal remains.

Laser cutting bridge. In textile manufacturing, a laser cutting bridge system is an industrial machine for cutting and engraving textile materials (i.e. fabrics). It is formed by a galvanometric laser head and carbon-dioxide laser ( laser) source that runs along an horizontal beam (the bridge) supported by two lateral columns and sometimes by central columns. This system is placed over one or more embroidery machines, more frequently multi-head rather than single-head machines, cutting tables and roller devices to cut out and/or engrave embroidered fabrics.

History
The first laser bridge for embroidery machines was invented and realized in 1998 by GMI srl an Italian company based in Vittorio Veneto (TV), Italy. The Laser cutting bridge was first presented to the public at the IMB exhibition of Cologne, Germany, in 2000. GMI srl continues manufacturing laser bridges and since 1998 has largely improved the quality of its cutting systems.

Before the advent of the laser bridge, fabrics were first die-cut and then appliqués were sewed or embroidered on the base fabric. Usually used as an 8 mm thick steel die with heights ranging from 50 to 100 mm depending on how many pieces were to be cut at once. This process proved to present numerous difficulties.

Technology
A cut piece of cloth (the appliqué) is placed above the base material that is in the embroidery machine (having a first seam reference), is fixed and finally embroidered. More recently, the manual method of cutting has been replaced by the laser cutting technology, laser plotters first, and then by laser bridges. The laser ensures better accuracy compared to manual cutting. It allows users to imitate a jagged or irregular cut as if done by hand, with the advantage that the laser solders the borders of synthetic fiber, avoiding unpleasant unthreading which is called "the clean edge". The combination "laser plus embroidery machine" offered by the laser bridge also avoids double work: no longer is it necessary to cut by hand after embroidering appliqués.

The process also guarantees more accurate results, because the laser works on the same frame where the embroidery machine works avoiding positioning errors. The technology uses software that guides the cutting laser head along the bridge and the reflecting mirrors (moved by electromagnetic motors). This method provides a degree of accuracy and speed of cut much greater than traditional systems (1/100 mm instead of 1/10 mm).

Waco 9. The Waco 9 is an American-built three-seat biplane design that first flew in 1925.

Development
The Waco 9 was the first of the steel-tubed fuselage aircraft designs to be built by the Advance Aircraft Company, which became the Waco Aircraft Company circa 1929. The Model 9 was a three-seat open cockpit biplane with the ailerons on the upper wings extending outboard of the main wing surfaces.

About 270 Model 9 aircraft were built during 1925 and 1926.

Operational history
The Model 9 was of rugged construction to meet the barnstorming requirements of the period. The cost when new was between $2,025 and $2,500. A Waco 9 was flown in the 1926 Ford National Reliability Air Tour.

The Model 9 was the first aircraft type to be fitted with aluminum floats (by the EDO Corporation in 1928). By 2007, a few examples remained airworthy in the US and five aircraft were held by museums.

Variants
Model 9s were fitted with a variety of engines including the  Curtiss OX-5, the  Curtiss OXX-6,  Curtiss C-6 and the  Hisso A. Fitment of the various engines did not change the model number.

Aircraft on display
A Waco 9, C116, "Miss McKeesport" is a part of the Ohio History Connection permanent collection. The airplane is currently on loan to the WACO Air Museum in Troy, Ohio. The airplane was constructed in 1927 and restored in 1985. It still retains its original Curtiss OX-5 engine.

A Waco 9, C218, is on display at the Western Antique Aeroplane & Automobile Museum located in Hood River, Oregon. It is displayed in the Pacific Air Transport Air Mail livery.

Shading coefficient. Shading coefficient (SC) is a measure of thermal performance of a glass unit (panel or window) in a building.

It is the ratio of solar gain (due to direct sunlight) passing through a glass unit to the solar energy which passes through 3mm Clear Float Glass. It is an indicator of how well the glass is thermally insulating (shading) the interior when there is direct sunlight on the panel or window.

The shading coefficient depends on the color of glass and degree of reflectivity. It also depends on the type of reflective metal oxides for the case of reflective glass. Sputter-coated reflective and/or sputter-coated low-emissivity glasses tend to have lower SC compared to the same pyrolitically-coated reflective and/or low-emissivity glass.

The value ranges between 1.00 to 0.00, but experiments show that the value of the SC is typically between 0.98~0.10. The lower the rating, the less solar heat is transmitted through the glass, and the greater its shading ability.

Solar properties play a significant role in the selection of glass, especially in regions or cardinal directions with high solar exposure. It becomes less significant in situations where direct sunlight is not a major factor (e.g., windows completely shaded by overhangs).

Window design methods have moved away from Shading Coefficient to Solar Heat Gain Coefficient (SHGC), which is defined as the fraction of incident solar radiation that actually enters a building through the entire window assembly as heat gain (not just the glass portion). Though shading coefficient is still mentioned in manufacturer product literature and some industry computer software, it is no longer mentioned as an option in the handbook widely used by building energy engineers or model building codes. Industry technical experts recognized the limitations of SC and pushed towards SHGC before the early 1990s.

A conversion from SC to SHGC is not necessarily straightforward, as they each take into account different heat transfer mechanisms and paths (window assembly vs. glass-only). To perform an approximate conversion from SC to SHGC, multiply the SC value by 0.87.

Subsurface dyke. A subsurface dyke is a structure that is built in an aquifer with the intention of obstructing the natural flow of ground water, thereby raising the ground water level and increasing the amount of water stored in the aquifer. Acting as an underground barrier impermeable to water, it controls the groundwater flow in an aquifer and raises the water table.

Introduction
Although the total amount of water on Earth is generally assumed to have remained virtually constant, the rapid growth in population, together with the extension of irrigated agriculture and industrial development, are putting stress on the quality and quantity aspects of natural system. Several institutions have experimented with the use of subsurface dykes to conserve water in water-scarce areas. The ideal location for a dyke is a well defined, wide, greatly sloping valley with a narrow outlet having limited thickness of loose soil or porous rock on the top with massive or impervious rock below. A subsurface dyke has many advantages. It does not require additional surface reservoir, there is no loss of agricultural land, there is minimum evaporation loss since the storage is subsurface, there is no siltation and loss of reservoir capacity, the cost of maintenance is negligible, and it is relatively environment-friendly.

One such example was a recent sub-surface dyke constructed in India. For more information about this project, see Krishi Vigyan Kendra Kannur.

Other water harvesting technologies
Other rainwater harvesting technologies include stone pitched contour bunds, dry rubble check dams, protection of seasonal spring by afforestation, moisture conservation pits, sprinkler and drip irrigation and roof water harvesting system.

Database-as-IPC. In computer programming, Database-as-IPC may be considered an anti-pattern where a disk persisted table in a database is used as the message queue store for routine inter-process communication (IPC) or subscribed data processing. If database performance is of concern, alternatives include sockets, network socket, or message queue.

British computer scientist, Junade Ali, defined the Database-as-IPC Anti-Pattern as using a database to "schedule jobs or queue up tasks to be completed", noting that this anti-pattern centres around using a database for temporary messages instead of persistent data.

Controversy

The issue arises if there is a performance issue, and if additional systems (and servers) can be justified. In terms of performance, recent advancements in database systems provide more efficient mechanisms for signaling and messaging, and database systems also support memory (non-persisted) tables.

There are databases with built-in notification mechanisms, such as PostgreSQL, SQL Server, and Oracle. These mechanisms and future improvements of database systems can make queuing much more efficient and avoid the need to set up a separate signaling or messaging queue system along with the server and management overhead.

While MySQL doesn't have direct support for notifications, some workarounds are possible. However, they would be seen as non-standard and therefore more difficult to maintain.

Waco Mailplanes. The Waco Mailplanes are US-built open-cockpit biplane mailplanes from the late 1920s derived from the Waco 10 sports biplanes.

Development
In order to meet the demand for mailplanes, Waco aircraft developed two models during 1929, the JYM and the JWM.

The JYM was a taperwing model based on the earlier ATO design but with a 14-inch fuselage stretch to provide further cargo capacity compared with the earlier design. It was powered by a  Wright J-6-9 engine and had a single seat cockpit for the pilot.

The JWM was a straight-wing model based on the ASO, also with a 14-inch longer fuselage and was fitted with a  Wright R-975 powerplant.

Operational history
Four Waco JYM aircraft were delivered to Northwest Airways (later Northwest Airlines) in 1929 and were operated on the  CAM-9 airmail route from Chicago to Minneapolis via Milwaukee, Madison and La Crosse. All four Waco JYM's still exist, with the third JYM NC631N on display at the Historic Aircraft Restoration Museum (HARM) at Dauster Field near St Louis, Missouri, wearing its 1929 NWAL CAM-9 route markings.  

One Waco JWM aircraft was built. The sole survivor NX8550 is also preserved at HARM, wearing the markings of the "Art Davis Air Circus".

Croxley Green Windmill. Croxley Green Windmill is a Grade II listed tower mill at Croxley Green, Hertfordshire, England which has been converted to residential accommodation.

History

Croxley Green Windmill was built c1860. Isaac Watts was the miller in 1861. He was living at Warden Hill near Luton, Bedfordshire in 1859. The mill was working by wind until the sails were blown off in the 1880s and from 1886 is recorded as having worked by steam engine only. The mill was last used to grind wheat in 1899 and after that it was used as a saw mill and turnery. By the 1930s the mill was used as a chicken house and pigeon loft. During the Second World War it was used as an Air Raid Precautions observation post, with an air raid siren mounted on the tower. The mill was converted to residential accommodation in the 1960s.

Description

Croxley Green Mill is a five-storey tower mill with a stage at second floor level. The tower has an internal diameter of  at ground level. It had a boat shaped cap winded by a fantail. The four Patent sails drove three pairs of millstones.
