Steensgaard's algorithm. In computer science, Steensgaard's algorithm is a scalable, flow-insensitive, algorithm for pointer analysis. It is often used in compilers, due to its speed (for example, an implementation is available in the LLVM compiler framework). In its original formulation, this algorithm was field-, context-, and array-insensitive.

Steensgaard's algorithm is based on equality constraints, as opposed to Andersen's algorithm, which is based on subset constraints. This allows points-to information to be tracked using a union-find data structure. This choice gives the algorithm its characteristic speed; when implemented using a union-find data structure it is linear space and almost linear time in the size of the input program.

Bjarne Steensgaard's formulation of the algorithm was in terms of type inference and type checking. Steensgaard proposed the points-to analysis for a small imperative but generic pointer language which captures the essential properties of other common languages with pointers, like C. The language semantics and typing rules constitute the analysis.

Field-effect tetrode. The tetrode field-effect transistor or field-effect tetrode is a solid-state semiconductor device, constructed by creating two field-effect channels back-to-back, with a junction between. It is a four-terminal device which does not have specific gate terminals because each channel is a gate for the other, the voltage conditions modulating the current carried by the other channel.

Current–voltage relationship
Where the voltage on the first channel is  and the voltage on the second channel is , the current in the first channel, , and the current in the second channel, , are given by:

and

,

where the  are the low-voltage conductance of the channels and  is the pinch-off voltage (assumed to be the same for each channel).

Applications

The field-effect tetrode can be used as a highly linear electronically variable resistor – resistance is not modulated by signal voltage. Signal voltage can exceed bias voltage, pinch-off voltage, and junction breakdown voltage. The limit is dependent on dissipation. Signal current flows in inverse proportion to the channel resistances. The signal does not modulate the depletion layer, so the tetrode can perform at high frequencies. The tuning ratio can be very large – the high resistance limit is in the megohms range for symmetrical pinch-off conditions.

Network documentation. Network documentation is a form of technical documentation, the goal of which is to maintain computer networks. It contains information about how the network is built, how it should perform, and where to troubleshoot problems. The purpose of network documentation is to keep networks running as smoothly as possible while minimizing downtime when repairs are necessary.

Parts 
Essential parts of network documentation include:

Map of the entire network, including hardware locations for servers and network equipment and cabling details
Metadata on the individual servers
Schedules and locations of backups
Metadata on installed software, including version numbers, installation dates, licensing details, and support information
Vendor and contractor information
Service agreements
Detailed record of problems, solutions, procedures, and results

Network documentations could contain charts, tables, diagrams, and even memory aids that help administrators locate information faster.

Documentation tools 
Though network documentation can be done by hand, large organizations must use network documentation software, including diagramming tools, inventory management, and circuit and cable traces. Examples include draw.io, Graphical Networks' netTerrain, Microsoft Visio, Docusnap, Gliffy, Opnet's Netmapper, and XIA Configuration.

WPrime. WPrime is a computer program that calculates a set number of square roots using Newton's method for estimating functions verifying the results by squaring them then comparing them with the original numbers.

Significance 
WPrime is popular in the overclocking community for testing the performance and stability of computer processors, as Super PI is single-threaded. Its popularity stemmed from being able to utilize 100% of a multi-core processor's computing time enabling its use as a multi-threaded benchmark application in competitions, computing reviews, and marketing campaigns.

Criticism 
The use of Newton's method for testing stability is inherently unreliable due to the self-correcting nature of the algorithm with subsequent iterations correcting any potential errors. WPrime would theoretically only detect instability from several consecutive errors. Additionally some have argued that the multi-threading algorithm used is not indicative of real world performance though much of this was due to poor implementations of multi-threading in consumer applications the early days of multi-core processors.

Air France fleet. Air France operates a fleet of 226 aircraft, most of which are manufactured by Airbus. The airline's fleet of narrow-body aircraft comprises all four Airbus A320 family variants. The airline's wide-body fleet, consisting of the Airbus A330, Airbus A350, Boeing 777, and Boeing 787, serve medium to long-haul routes. The airline had also ordered the short-haul Airbus A220-300s to replace their aging Airbus A318s and A319s. In September 2023, Air France-KLM announced an additional order for 50 Airbus A350s to replace their Airbus A330s and their Boeing 777-200ERs.

KLM fleet. The Dutch flag carrier airline KLM operates a fleet of 116 aircraft. The narrow-body fleet is composed of Boeing 737 Next Generation aircraft which will be replaced by the Airbus A320neo family aircraft in 2024. Airbus A330, Boeing 777 and Boeing 787 Dreamliner wide-body aircraft are used on medium and long-haul flights. In September 2023, Air France-KLM announced an order for 50 Airbus A350s. These will replace the group's remaining Airbus A330s and Boeing 777-200ERs, and will be shared between Air France and KLM.

Fleet strategy

KLM's first of eight Boeing 787-10 aircraft was delivered on 28 June 2019; it featured centennial markings.

On 19 June 2013, KLM had ordered seven Airbus A350-900s. In June 2019, Air France–KLM announced that KLM will not take up any of the group's ordered A350s because of fleet rationalization purposes.

CEO Ben Smith has announced at Air France's Investor Day (5 November 2019) in Paris that "in the near future", KLM will only use the Boeing 777 and 787 as their long and medium-haul fleet, respectively, after retiring their thirteen Airbus A330s. This move would have made KLM an all-Boeing carrier, however KLM announced in December 2021 that an order was placed for 100 Airbus A320neo family aircraft which will be shared with Transavia and Transnavia France. This order will replace KLM's short-haul Boeing 737 fleet alongside Transavia's.

There was considerable speculation on the replacement of KLM’s aging 777 and A330 fleet, of which the oldest 777-200ERs date back to 2003. On the 23rd of August 2023, it was reported that contrary to prior speculation that KLM was considering Airbus A350 and Boeing 777X aircraft types, it would likely opt to further increase the number of Boeing 787 Dreamliner aircraft in the existing fleet. This was disproven when Air France–KLM placed an order for 50 Airbus A350s.

Special liveries
KLM has several aircraft painted in special liveries; they include:
 PH-BVA, a Boeing 777-300ER, features an orange forward fuselage that fades into the standard blue to commemorate the Netherlands national team's participation in the 2016 Summer Olympics in Rio de Janeiro.
 PH-KZU, a Fokker F70, has been applied with a special livery featuring Anthony Fokker, the founder of Fokker, commemorating the airline's long-standing history with Fokker aircraft and the phase-out of the Fokker 70 aircraft in October 2017.
 Several aircraft wear the silver SkyTeam alliance livery, including PH-BVD (a 777-300ER) (this one has been repainted to the original KLM colors but with the blue going a little further down at the nose), PH-BXO (a 737-900) and PH-EZX (a KLM Cityhopper ERJ-190).
PH-BKA, a Boeing 787-10, features the standard KLM livery with a 100 wrapped around its lettering on the plane to commemorate the airline's centennial.

As the Japanese government plans to add more slots at Tokyo's Haneda Airport by 2020 (in time for the 2020 Summer Olympics), Japan Airlines intends to order more wide-bodies for growth in 2018 or 2019: it could exercise its 25 options on Airbus A350s on top of its 31 firm orders, due for delivery from 2019, and study others such as the proposed Boeing New Midsize Airplane or the 787-10 to add to its 787-9 with 10 remaining to be delivered. Japan Airlines' Airbus A350 is currently maintained via the MRO subsidiary of Safran, OEMServices.

Japan Airlines operates a mixture of narrow-body and wide-body aircraft. The airline provides economy class service on all routes; business class (J) service with larger seats in the cabin front on most major domestic routes; premium economy on some international routes; business class on all international routes; and first class on some long-haul and domestic routes.

On 5 December 2017, JAL announced it had invested $10 million in the aircraft manufacturer Boom Supersonic, which is currently developing a new supersonic commercial airliner capable of seating up to 55 passengers. In exchange for its funding, JAL will be able to pre-order up to 20 Boom aircraft.

Cargo
JAL Cargo is a freighter airline operating for JAL. It ended dedicated freighter aircraft operations in October 2010 after more than 30 years of service. It operated both propeller and jet aircraft through the years, most recently, Boeing 747-400s (including aircraft converted from passenger to freighter configuration) and Boeing 767-300Fs. However, in 2023, JAL announced that they would bring back dedicated cargo 767 freighters, in a response to changes in labor regulations forcing Japanese truckers to work less hours.

Kongsberg School of Mines. Kongsberg School of Mines () was an academic institution for mining technology in Kongsberg, Norway from 1757 to 1814.

History
At the 1769 Census, Kongsberg was the second largest city in Norway (after Bergen), with more than 8,000 inhabitants, and the number of employees at the Kongsberg Silver Mines exceeded 4,000.

In 1757, after an initiative from mining engineer Michael Heltzen and chemist and physician Johan Heinrich Becker, Det Kongelige Norske Berg-Seminarium was established by an Order in Council from Frederick V of Denmark dated 19 September 1757. The institution combined both practical and theoretical education related to mining. Among the theoretical subjects were mathematics (in particular geometry and trigonometry), mechanics (for construction of buildings and machinery), hydrostatics, hydraulics, physical chemistry, mineralogy, metallurgy and pyrotechnics. The new school building from 1783 has been preserved. The institution had a library of about 900 books on mining, mineralogy, chemistry, physics and mathematics.

The mining curricula were eventually transferred to Christiania, after the Universitas Regia Fredericiana was established (1811–). After the establishment of the Norwegian Institute of Technology in the 1910s, the education of mining engineers was further moved to Trondheim.

Today, the historical building is owned by the Kongsberg Group, which, in collaboration with the University of Southeast Norway (USN), plans to renovate the building into a modern center for knowledge and innovation, thereby helping to shape the technological landscape of the future.
