Kobler Field. Kobler Field is a former a World War II airfield on Saipan in the Mariana Islands, part of Naval Advance Base Saipan.  It was closed in 1977 and redeveloped as a residential housing area.

History

World War II
Kobler Field was constructed between August and October 1944 near Aslito on the southern end of Saipan as a base for Twentieth Air Force B-29 Superfortresses carrying out the strategic bombing campaign against the Japanese Home Islands. The facility had a  runway, repair and maintenance facilities, and hardstanding for 120 aircraft. The airfield was named after Lt. Wayne F. Kobler, a 19th Fighter Squadron pilot who was killed on 27 June 1944 while flying his P-47 on a low-level attack mission on Tinian.

As Isely Field, North Field, and West Field on Tinian became operational, Kobler Field was increasingly used by the Twentieth Air Force as an auxiliary field for storage and basing of miscellaneous aircraft.

A LORAN navigation station was established at the end of Kobler Field in November 1944, which the United States Coast Guard continued to operate until January 1978.

The 819th Bombardment Squadron flying B-24 Liberators deployed to Kobler Field in August 1944 to undertake attacks on Japanese islands and shipping.

On 22 June 1945, following a raid on Kure Naval Arsenal, a B-29 crashed at Kobler Field while attempting to land on two engines.

Postwar
In the postwar era, Kobler Field was transferred to US Navy administration and remained under US Navy control until placed out of service in the early 1960s. VF-13A flying F4U-4s operated from Kobler Field from 1946 into 1947. VA-12 was shore-based at NAB Kobler Field from 21 August–19 September and November–December 1946.VA-1A was shore-based at NAB Kobler Field from 28 December 1946 until 9 January 1947. Carrier Aircraft Service Unit (CASU) 47 was also based at NAB Kobler Field.

On 16 May 1968, Continental Micronesia's first commercial flight, a Boeing 727-100 jet known as Ju Ju, took off from Kobler Field to Honolulu International Airport. Kobler Field operated as the main airfield on Saipan until 25 July 1976, when operations were moved to Saipan International Airport.

Current status
Following its closure, Kobler Field was redeveloped as Koblerville, a residential housing area. One runway is now Beach Road/Koblerville Road. Saipan Southern High School and Koblerville Elementary School are located in the path of the second runway.

Pierre Geneves. Pierre Genevès is a French computer scientist born in 1980. He is a research scientist at CNRS and recipient of the 2013 CNRS Bronze medal.

Biography 
Born in Cahors in 1980, Pierre Genevès founded in 2001 a software company developing a graphic software, later marketed under the name of AceDesign Pro by the Canadian software company Visicom Media.

He worked at IBM Research in New York City in 2003 and 2004 where he studied the design of scalable architectures for querying and transforming flows of structured data.

He graduated from the university of Grenoble from which he received a PhD in computer science in 2006. His thesis, concerning computational logic for reasoning on tree-shaped data, was awarded the EADS prize for the best PhD thesis in 2007, and the prize for the best PhD thesis from the INPG university in 2008.

After a post-doctorate at the Swiss Federal Institute of Technology in Lausanne (EPFL) 2007, he joined CNRS where he studied and contributed to the field of modal logics, like the modal mu-calculus, that he used for modeling query languages, and allow for the automated reasoning about programs that manipulate structured data. Pioneer of the static analysis of cascading style sheets for web pages, his results in logic also apply to the fields of programming languages, software engineering and artificial intelligence.

Drucker stability. Drucker stability (also called the Drucker stability postulates) refers to a set of mathematical criteria that restrict the possible nonlinear stress-strain relations that can be satisfied by a solid material.  The postulates are named after Daniel C. Drucker. A material that does not satisfy these criteria is often found to be unstable in the sense that application of a load to a material point can lead to arbitrary deformations at that material point unless an additional length or time scale is specified in the constitutive relations.

The Drucker stability postulates are often invoked in nonlinear finite element analysis.  Materials that satisfy these criteria are generally well-suited for numerical analysis, while materials that fail to satisfy this criterion are likely to present difficulties (i.e. non-uniqueness or singularity) during the solution process.

Drucker's first stability criterion 
Drucker's first stability criterion (first proposed by Rodney Hill and also called Hill's stability criterion) is a strong condition on the incremental internal energy of a material which states that the incremental internal energy can only increase.  The criterion may be written as follows:
,
where dσ is the stress increment tensor associated with the strain increment tensor dε through the constitutive relation.

Drucker's stability postulate 
Drucker's postulate is applicable to elastic-plastic materials and states that in a cycle of plastic deformation the second degree plastic work is always positive.  This postulate can be expressed in incremental form as
,
where dεp is the incremental plastic strain tensor.

Voerster's Independent Company of Sappers and Miners. The Voerster's Independent Company of Sappers and Miners was an independent company of military engineers that served in the Union Army during the American Civil War.

The Company was organized in St. Louis, Missouri under the authority of Major General John C. Frémont. The company was intended to provide engineering and pioneer support to the Army of the West operating at that time in the state of Missouri. While the company was subsequently consolidated with other organizations, it appears to have continued to carry out specialized engineering functions, at least thought the end of 1862 and possibly later.

Service
Attached to Army of the West and Unattached District of Southwest Missouri, Dept. of Missouri. Engaged in road repair and construction between Rolla and Springfield, Missouri.

On March 18, 1862, Special Orders No. 43 of the Adjutant General of Missouri ordered Voerster's Independent Company of Sappers and Miners consolidated with other units to form the 5th Missouri Volunteer Infantry. The company appears to have continues to be considered to be a specialized company of engineering specialists.

On December 3, 1862, the company (commanded by Captain J. E. Hensler), and by then known as Company "I (Sappers and Miners)", 5th Missouri Volunteer Infantry, was reassigned, becoming Company "I",  35th Missouri Volunteer Infantry. The history of the "Company of Sappers and Miners" merges with the 35th Missouri from this point.

At least some of the members of Company "I" were subsequently transferred to the 1st Regiment Missouri Volunteer Engineers.

Warpalizer. Warpalizer is a professional warp and blend software application made by Univisual Technologies AB in Sweden, for use in simulators.

Warpalizer can be used for projection on to surfaces that need image geometry correction (warping) to improve the image from the projector, on a cylindrical screen for example. When used with multiple projectors Warpalizer uses edge blending to display the images from the different projectors without seams.

In 2013 Warpalizer was used in a 24 channel (projectors) excavator simulator, based on 1 server and 24 clients.

Disc cutter. A disc cutter (also known as a power cutter or a concrete saw) is a specialised, often hand-held, power tool used for cutting hard materials, ceramic tile, metal, concrete, and stone for example. This tool is very similar to an angle grinder, chop saw, or even a die grinder, with the main difference being the cutting disc itself (a circular diamond blade, or resin-bonded abrasive cutting wheel for a disc cutter vs. an abrasive grinding wheel for an angle grinder). This tool is highly efficient at cutting very hard materials, especially when compared to hand tools.

Discs 
Often cutting discs, also known as cut-off wheels, are made from a solid abrasive disc. These discs are often used for cutting metal; they are composed of an abrasive mix of grit and adhesive that is formed into a thin, rigid disc with fiber webbing running through it for strength. Some discs used for cutting ceramic tile or stone are made from a solid disc with an edge coated with diamond grit. The most common size for these cutting wheels is  inches in diameter; however they can range from 2 to 16 inches in diameter with a thickness range from .045 in. to .125 in. Type 1 discs are flat, and type 27 discs have a raised hub. These wheels are strong but are not immune to breaking. If a cutting wheel breaks while in use, fragments could injure the operator or nearby co-workers. To avoid breaking cutting discs, never exceed the maximum speed (RPM) specified on the disc, and do not overload the disc by cutting with excess force or jamming the wheel into your workpiece.

Applications 
Many manual cutting tasks require a hand-held grinder using a cutting wheel. Metal fabrication is one of the most common uses for cutting wheels. Cutting sheet metal, sizing metal stock for welding, cutting a weld to re-weld it, and cutting and notching steel pipe are just a few examples. Die grinders and chop saws are other common tools used with cutting discs.

Smaller projects and smaller or more precise cuts may require a die grinder equipped with a cutting wheel. These cutting wheels or discs are extremely thin and often less than 2 inches in diameter. Because they are so thin, they are commonly made of metal and have a diamond-coated edge as the abrasive. This type of disc cutter is good for sheet metal and for lightweight or thin materials. Thicker or heavier materials will need a larger disc cutter.

For long straight cuts on sheet metal or for light cut-off work, a standard circular saw is used with a -inch cutting wheel. These cutting discs are made just like the smaller wheels of an angle grinder, with resin bonded abrasive material, or are of metal with a diamond-coated edge.

A cutoff saw is used for cutting larger items, like heavy metal stock, metal studs, and for cutting large metal pipe. The cutting discs for this tool are usually 10 or 12 inches in diameter, with a composition like that of the smaller wheels mentioned above. When cutting heavy materials the cutting discs may require lubrication or coolant to prevent overheating. The cutoff saw is for making clean straight 90 degree cuts through the material.

Borate glass. Borate glasses have a more complex action of alkali ions than silicate glasses. Borate glasses also have major differences in their optical properties.

The single largest use of boron compounds in the world (accounting for half of total global use) is the production of certain types of boron-treated glass fiber for insulating and structural fiberglass. In these uses the boron may be present as borax or boron oxide, and adds to the structural strength of the glass as borosilicate, or is added as a fluxing agent to decrease the melting temperature of pure silica, which is difficult to extrude as fibers and work with in pure form, due to the high temperatures involved.

Cupping tester. Cupping testers are employed in the testing of the elongation and deformability of lacquers and protective coatings applied to metal substrates. This sort of test is essential because it allows one to test the durability of a lacquer or protective coating before the coating is applied to a product.

Operation
The cupping tester operates by using a punch to push upon the unpainted side of a coated panel until the painted side shows signs of deformation (cracks) in the coating.  It is when cracks start to appear that the lacquer or coating's durability can be recorded, this durability is known as the coating's flexibility rating.

The test can also be performed according to a predetermined depth.  For example, if a coating needed a certain flexibility rating, then the tester would be set to a depth in accordance with that rating, without the need to deform the coating until it fails.

Appearance
There are a variety of cupping testers, ranging from the manual to the fully automated, and from single substrate to multiple substrate testers.  However, generally they consist of a solid metal base which forms a circle over which the coating is tested.  There is a punch that will go up to and through this metal hole in order to apply pressure to the coating and substrate.  In addition to these core components, there is usually an included magnifier which helps to determine the point of major deformation.  These components can be arranged in a variety of ways, but these components remain consistent in all designs.

Eidgenoessische Konstruktionswerkstaette. Eidgenössische Konstruktionswerkstätte English: "Federal Constructions Works", short K+W, was a Swiss state-owned enterprise, with the aim of making the Swiss military independent of foreign sources for its equipment needs. It was established in 1867 in Thun and produced artillery, vehicles and other typical military equipment. In 1914 Switzerland put in an effort to make itself independent of foreign suppliers of military aircraft and started the production of the DH-1 in Thun. Long-standing connections to the ETH Zurich ensured the necessary know-how. 1940 the aviation department moved from Thun to Emmen (LU) and in 1943 it became a separate unit of the Swiss Armed Forces independent under the name of Eidgenössisches Flugzeugwerk (F+W) (Federal Aviation Works). The Eidgenoessische Konstruktionswerkstaette focused now on the production of armoured fighting vehicles for the Swiss Army, both of its own designs and licensed production of M113 armored personnel carriers and Leopard 2 tanks and other land systems for the Swiss Army. Since 1995 it changed its name several times, started exporting and is now part of RUAG Defence.

There is a museum of the company tanks in Thun, Bern, Switzerland.
