Kellner-Béchereau. Avions Kellner-Béchereau, known as Kellner-Béchereau, was a French aircraft manufacturer of the early 20th century.

History
The company was founded in 1931 by Louis Béchereau together with the French automobile carriage-builder Georges Kellner. The factory, located at Boulogne-Billancourt, began building light monoplanes. In 1936–37 Avions Kellner-Béchereau built a short series of small monoplanes exploiting one of Louis Béchereau's patents, a full span lateral division of the wing into two sections forming a "double wing".

The wing was first tested on the single-seat Kellner-Béchereau E.1 on 1936, which was followed by two larger and more powerful two-seaters, the Kellner-Béchereau EC.4 and ED.5.  Both of these were designed to meet the French Air Ministry's requirement for a pre-military trainer aircraft to be used by the clubs set up in the "Aviation Populaire" programme. The Kellner-Béchereau designs, however, were not ordered for the Aviation Populaire programme, the Air Ministry opting in favour of the Caudron C.270 and the Salmson Cri-Cri which were both bought in large numbers. Instead, Kellner-Béchereau, along with other manufacturers, built the Cri-Cri under licence.

On the eve of the Second World War, Louis Béchereau conceived a monoplane, the Kellner-Béchereau E.60, also known as K.B.E 60, an embarked monoplane for the aircraft carriers of the French Navy, but its development was frustrated by events.

In 1939 Georges Paulin, who in 1934 had designed the Peugeot 601 Éclipse convertible automobile, joined the aerodynamical department of the Kellner-Béchereau factory. A member of the French Resistance, he was arrested in 1941 and executed the following year. The Kellner-Béchereau factory was destroyed by bombing in 1942 and the Avions Kellner-Béchereau company was subsequently merged with Morane-Saulnier. Louis Béchereau was given a post as a director at Morane-Saulnier until his retirement in 1950.

Grinder-mixer. A grinder-mixer is a type of agricultural machine used to process livestock feed from grain. It is a portable mill that combines the mixing and grinding operations.

Grinding of ingredients generally improves feed digestibility, acceptability, mixing properties and pelletability.

Grain is typically pulverized in a grinder-mixer either by hammer mills or roller mills.

Hammermills are impact grinders with swinging or stationary steel bars forcing ingredients against a circular screen or solid serrated section designated as a striking plate. Material is held in the grinding chamber until it is reduced to the size of the openings in the screen. The number of hammers on a rotating shaft, their size, arrangement, sharpness, the speed of rotation, wear patterns, and clearance at the tip relative to the screen or striking plate are important variables in grinding capacity and the appearance of ground feed.

A combination of cutting, attrition, and crushing occurs in roller mills. These are smooth or corrugated rolls rotating at the same speed set at a pre-determined distance apart with material passing between the two. A tearing action may be added by operating the rolls at different speeds and by different for each roll.

The objective of feed mixing is to start with a certain assortment of ingredients called a "formula", totaling some definite weight. This is processed so that each small unit of the whole, either a mouthful or a day's feeding, is the same proportion as the original formula. The mixing process is done in the vertical tank. It determines the balanced nutritional quality of the feed.

After the feed is ground and mixed, it passes through a system of particulate screens. From there, only suitable granules pass on to the delivery process, and waste is sent to the charging chute.

Μ(I) rheology. {{DISPLAYTITLE:μ(I) rheology}}
In granular mechanics, the μ(I) rheology is one model of the rheology of a granular flow.

Details

The inertial number of a granular flow is a dimensionless quantity defined as

where  is the shear rate tensor,  is its magnitude, d is the average particle diameter, P is the isotropic pressure and ρ is the density. It is a local quantity and may take different values at different locations in the flow. 

The μ(I) rheology asserts a constitutive relationship between the stress tensor of the flow and the rate of strain tensor:

where the eponymous μ(I) is a dimensionless function of I. As with Newtonian fluids, the first term -Pδij represents the effect of pressure. The second term represents a shear stress: it acts in the direction of the shear, and its magnitude is equal to the pressure multiplied by a coefficient of friction μ(I). This is therefore a generalisation of the standard Coulomb friction model. The multiplicative term  can be interpreted as the effective viscosity of the granular material, which tends to infinity in the limit of vanishing shear flow, ensuring the existence of a yield criterion.

One deficiency of the μ(I) rheology is that it does not capture the hysteretic properties of a granular material.

Development

The μ(I) rheology was developed by Pierre Jop et al. in 2006. Since its initial introduction, many works has been carried out to modify and improve this rheology model. This model provides an alternative approach to the Discrete Element Method (DEM), offering a lower computational cost for simulating granular flows within mixers.

Cray Urika-XA. The Cray Urika-XA extreme analytics platform, manufactured by supercomputer maker Cray Inc., was an appliance that analyzes the massive amounts of data—usually called big data—that supercomputers collect. It was introduced in 2015 and discontinued in 2017. Organizations that use supercomputers have traditionally used multiple smaller off-the-shelf systems for data analysis. But as organizations see a dramatic increase in the amount of data they collect—everything from research data to retail transactions—they need data analytics systems that can make sense of it and help them use it strategically. In a nod to organizations that lean toward open-source software, the Urika-XA comes pre-installed with Cloudera Enterprise Hadoop and Apache Spark.

USS Hopi. USS Hopi (AT-71) was a  constructed for the United States Navy during World War II. Her purpose was to aid ships, usually by towing, on the high seas or in combat or post-combat areas, plus "other duties as assigned." During World War II she was assigned to the Europe-Africa-Middle East Theater where she participated in four campaigns earning four battle stars.

Description

Hopi was laid down 5 May 1942 by Charleston Shipbuilding and Drydock Co., Charleston, South Carolina and launched on 7 September 1942. She was commissioned 31 March 1943.

World War II service
After shakedown training in Key West the Hopi left for New York and then was deployed with a convoy for North Africa on 10 June 1943 to join the Europe-Africa-Middle East Theater.

Sicilian occupation
Upon arrival she was tasked with performing towing services for several days before steaming to Bizerte to join Vice Admiral Hewitt's Western Naval Task Force for the assault on Sicily. Departing Bizerte 8 July with pontoons in tow, Hopi landed them 2 days later and immediately set to work clearing the beaches of damaged landing craft and fighting fires on vessels in the transport areas.

Salerno landings
She returned to Bizerte 10 August to prepare for the Salerno operation. She sailed early in September and again performed salvage work. On 11 September, , while lying-to in the support area awaiting calls for support, received a direct hit on No. 3 turret which left her dead in the water. Hopi and salvage tug  immediately came alongside. Work by these two tugs allowed  to return to Malta that under her own power. On 16 September,  took multiple hits from guided bombs. Hopi and Moreno were able to tow her to Malta without further incident.
