Grulich S.1. The Grulich S.1 was a German parasol monoplane with a cantilever wing, built in the mid 1920s. It seated two and offered a choice between two engines.

Design and development

The Grulich S.1 was designed by Dr. Ing. Karl Grulich, an engineer associated with Gothaer Waggonfabrik, the company which had produced the Gotha series of bombers in World War I. Before the war he had designed and flown the Harlan monoplane and post-war was also associated with Deutsche Aero-Lloyd, a German airline that by January 1926 had merged with Junkers Luftverkehr into  Deutsche Luft Hansa.

Its cantilever wing was straight-tapered, with no sweep on the leading edges, and with long, curved tips. It was built around two spars and was very thick centrally but thinned outwards; there was no dihedral on the upper surface but the thinning produced significant overall dihedral.  Tapered ailerons filled about half the span. The wing was mounted over the fuselage on a cabane of four sloping metal struts to the front spar and another six to the rear.

The S.1 was designed to be powered by one of two Siemens-Halske radial engines, a seven-cylinder  Sh 5 or a nine-cylinder  Sh 6, mounted in the nose under a cowling which left the cylinders exposed for cooling. Its fuel tank was in the wing.

Behind the engine the fuselage had a tapering, rectangular section. There were two open cockpits in tandem, fitted with dual controls. Both were under the wing, though there was a small cut-out in the trailing edge over the rear position. The empennage was conventional, with a slightly rounded fin and deep rectangular rudder. A large area tailplane was mounted on top of the fuselage, with split elevators to allow rudder movement.

The S.1 had conventional, fixed landing gear. Metal V-form landing legs from each side of the lower fuselage, strut-reinforced laterally, carried a single axle attached via rubber chord shock absorbers.  The mainwheels were well outboard of the V-struts, giving a track of .

The exact date of the S.1's first flight is not known; it was complete by mid-1925 but may have flown earlier. It was registered as D-584 in that year, given the name Hessen and owned initially by Deutsche Aero-Lloyd. Later used by Hessiche Flugbetriebs from Darmstadt, its registration was cancelled in 1932.

Savines Bridge. The Savines Bridge (Pont de Savines) is a 924m concrete viaduct (box girder bridge) in Savines-le-Lac, in the Provence Alps and Prealps of south-east France, built in 1960. It crosses a reservoir of the Durance river.

History

Design
The bridge was designed by Jean Courbon, a famous bridge engineer with the Société d'Études et d'Équipements d'Entreprise, or SEEE of Rue Salvador Allende in Nanterre. It was one of the first post-tensioned prestressed concrete (béton précontraint) bridges built in France.

The concrete piers are 16 foot 5 inches square with 16 inch thick concrete walls.

Construction
It was built by Entreprise GTM, with construction starting in 1958. It was built with the balanced cantilever, or free cantilever, method, and mobile cantilever scaffolding. The reservoir (retenue du barrage) began construction in 1955 and was finished in June 1960.

The bridge was built before the valley had been flooded, and the concrete piers are much higher than they may look.

Structure
It is situated in the Hautes-Alpes department in the Provence-Alpes-Côte d'Azur region in the far east of southern France. It crosses the Lac de Serre-Ponçon, an artificial lake or reservoir. The creation of the lake prompted the 1958 film, Girl and the River. It carries the N94 (Route Nationale RN 94) road.

Charles Henry Parr. Charles Henry Parr (March 18, 1868 – June 10, 1941) was an American mechanical engineer, inventor, and pioneer in developing the gasoline-powered agricultural tractor and cofounder of the Hart-Parr Company.

Early life and education
Parr was born March 18, 1868, in Wisconsin, the son of Martha and John Parr. He had five siblings. He attended high school in Dodgeville, Wisconsin, before attaining a degree in mechanical engineering from the University of Wisconsin–Madison, where he met his future partner, Charles Walter Hart. Both men graduated with honors.

Career

After graduation, while still in Madison, Parr and Harr established a small engine company. They then moved to Charles City, Iowa, where Hart was born, and started the Hart-Parr Company. In 1902, they developed a gasoline engine for tractors and one year later invented the first known kerosene-run engine, which needed just 50% of the fuel  that ran the gasoline engine. Also 1903, they built the country's first internal combustion engine. For a time, Hart-Parr tractors were a leading type, sold in the US and other countries. During World War I, the company also made shells for the army.

Parr left the company in 1923 to work for the Street Sweeper Company in Elgin, Illinois, but returned and stayed with Hart-Parr and the successor Oliver Farm Equipment Company until he died in 1941.

Personal life
He married Gertrude Gates of Beloit, Wisconsin, in August 1898. They had a son and five daughters. He served on the library and school boards and was a leader of the First Congregationalist Church. He was also an active member of the Freemasons, including high priest of the Royal Arch Masons and commander of the Knights Templar. During a family vacation to Los Angeles, California, Parr died on June 10, 1941. Gertrude died months earlier, February 17, 1941. They are buried at Riverside Cemetery, Charles City, Iowa.

His home, the Charles Henry Parr House, in Charles City, Iowa is listed on the National Register of Historic Places.

Dot Stool - Models 3170 and M3170. The Dot stool (Model 3170) is an example Danish Mid-century modern seating design. It was designed and developed by Fritz Hansen in the early 1950s and refined for production in 1954 through a collaboration with Arne Jacobsen. The Dot stool design was modified (Model M3170) in the 1960s by Jacobsen and was produced in 1969.
	 
The Model 3170 stools were constructed of chrome plated tubular steel, plastic, and a bent wood veneer seat. The design of the stool allowed for groups to be neatly and easily stacked. The stools produced from 1954 to 1970 had three legs, and after 1970, the design changed to feature 4 legs. The 3170 stool is still being offered by retailer Republic of Fritz Hansen. It measures 17.3 inches high.

The Model M3170 were constructed of chrome plated tubular steel, plastic, and a bent wood veneer seat. It measures 24 inches high, taller than the Model 3170, and featured a steel foot rail along the bottom legs, creating a triangular shape. This model was only produced for one year in 1969.

ARM Cortex-A75. The ARM Cortex-A75 is a central processing unit implementing the ARMv8.2-A 64-bit instruction set designed by ARM Holdings's Sophia design centre. The Cortex-A75 is a 3-wide decode out-of-order superscalar pipeline. The Cortex-A75 serves as the successor of the Cortex-A73, designed to improve performance by 20% over the A73 in mobile applications while maintaining the same efficiency.

Design
According to ARM, the A75 is expected to offer 16–48% better performance than an A73 and is targeted beyond mobile workloads. The A75 also features an increased TDP envelope of 2 W, enabling increased performance.

The Cortex-A75 and Cortex-A55 cores are the first products to support ARM's DynamIQ technology. The successor to big.LITTLE, this technology is designed to be more flexible and scalable when designing multi-core products.

Licensing
The Cortex-A75 is available as SIP core to licensees, and its design makes it suitable for integration with other SIP cores (e.g. GPU, display controller, DSP, image processor, etc.) into one die constituting a system on a chip (SoC).

ARM has also collaborated with Qualcomm for a semi-custom version of the Cortex-A75, used within the Kryo 385 CPU. This semi-custom core is also used in some Qualcomm's mid-range SoCs as Kryo 360 Gold.

MARMOK-A-5. MARMOK-A-5 is an offshore electrical power generator that uses wave energy to create electricity. This device is a spar buoy installed in the maritime testing site BiMEP, in the Bay of Biscay. It is the first grid-connected maritime generator in Spain, and one of the first in the world.

Developed by the Basque company Oceantec Energias Marinas inside the European project OPERA, it is delivering electrical energy to the grid since December 2016. The buoy is located in the ocean, 4 km from the coastline and is connected to the sea with a submarine electrical cable. With a nominal power of 30 kW, the principal aim of the MARMOK-A-5 device is obtaining results in the way of designing a new generation cost effective high power marine energy generator.

Principle 
The operation principle of MARMOK-A-5 is a point absorber OWC (Oscillating Water Column). The device is 5m in diameter and a length of 42m, 6m above the water. It has a weight of more than 80 tons. The buoy is floating in a 90m depth and is tied to the sea bed with a mooring system based on anchors. This wave energy converter has demonstrated its robustness surviving difficult environmental conditions with waves as big as 12m.

History 
As noted above, the concept was initially developed by Oceantec within the European OPERA project.

Further development in EuropeWave programme 
IDOM were one of seven companies awarded pre-commercial procurement funding in December 2021 for Stage 1 of the EuropeWave programme, to further develop the device concept. In September 2022, they progressed to Stage 2 with additional funding for a Front-End Engineering and Design study of a scale-prototype to be tested at sea. IDOM were one of three concepts that progressed to Stage 3, with a share of the €13.4m budget to develop and test a device at BiMEP for a year.

EnDrain. EnDrain is software for the calculation of a subsurface drainage system in agricultural land. The EnDrain program computes the water flow discharged by drains, the hydraulic head losses and the distance between drains, also obtaining the curve described by water-table level. Such calculations are necessary to design a drainage system in the framework of an irrigation system for water table and soil salinity control.

Particulars

EnDrain is a model for a drainage equation. It offers the possibility to calculate drain spacing given the elevation of the water table or, alternatively, the elevation given the spacing. It can also calculate the hydraulic conductivity, given spacing and elevation.

The program allows the utilization of three different soil layers, each of them with their own permeability and hydraulic conductivity (vertical and horizontal, anisotropy), one layer being above and two layers below drain level.

The calculation of distances between drains and other parameters is based on the concept of the energy balance of groundwater flow and the hydraulic equivalent of Joule's law. For comparison, the classical concepts based on theories of Darcy and Dupuit are also used.
