Aligarh Airport. Aligarh Airport  is an domestic airport situated at Aligarh - Sikandra Rao Road in outskirts of Aligarh city in the Indian state of Uttar Pradesh. It is being developed by upgrading the existing government airstrip.

First phase
Aligarh Airport in Dhanipur, Aligarh is going to be completed in the March 2024. The license for flying has been issued on the very first day of the New Year. Preparations are on to start operating a 19 seater aircraft from here.

19-seater aircraft started in the second phase on 11 March 2024 from Lucknow to Aligarh 

 
While starting air travel between Aligarh and Lucknow, there were indications of starting travel from Aligarh to Kanpur, Aligarh to Azamgarh and other places. The aviation company which is operating flights from Aligarh is making preparations to start travel from Aligarh to Azamgarh first at the level of the same company.

Second phase
In the second phase, flight services to other cities are to be started from here through 90-seater aircraft. Even the biggest aircraft like Airbus-320 and Boeing-737 will be able to land here. This airport is being prepared for international standards. A 3.3 km long runway is also being prepared. The Airport Authority has demanded 675 acres of land for the runway. Out of this, about 300 acres of land has been acquired, while 376 acres of land is being acquired further.

Jhansi Airstrip. Jhansi Airstrip  is a military airstrip situated in Jhansi city in the Bundelkhand region of Indian state of Uttar Pradesh, which is run by the Army Aviation Corps and owned by Uttar Pradesh Government. The airstrip covers an area of 198 acres. Establishment of an airport was proposed by government by upgrading the existing government airstrip, which is now replaced by a new greenfield airport project.

History 
Jhansi airport was handed over by the DGCA to the National Airports Authority in 1986. The airport was then handed over for maintenance to the UP Government. In 1990, the State Government handed over the air field to the Indian Army.

Extension plan
The Uttar Pradesh government has prepared a blueprint to expand and develop Jhansi airport to open up the backward Bundelkhand region for tourism. Its development as a civil airport would facilitate easy access to Khajuraho (150 km away in Madhya Pradesh) and boost to tourism in and around Jhansi, which is the nerve centre of Bundelkhand. The airstrip has existed from the British days and is largely used for military purposes. The clearances for development of the airstrip into a full-fledged airport has been given by highest level in the state. Through Regional connectivity scheme soon a Jhansi-Lucknow flight will start.

Lucknow-Jhansi route was selected under UDAN 2, but flight operations have not commenced yet. Jhansi-Agra and Jhansi-Khajuraho routes have been suggested for UDAN 3 by the government.

New Airport
In December 2021, Amar Ujala newspaper reported that extension plans are replaced by a new Greenfield Airport proposal.

Datia Airport

In 2023, Airport Authority of India started to upgrade the Datia Airstrip into Datia Airport which is near Jhansi city but in Madhya Pradesh state. Proposed Datia Airport is 29 kilometres away from Jhansi City and will serve both cities of Datia and Jhansi.

Logan (automobile). The Logan Construction Company was founded in 1903 in Chillicothe, Ohio. They were manufacturers of the Logan automobile until 1908.

History 
Benjamin A. Gramm was the designer of the Buckeye and Gramm automobiles before entering production with the Logan in 1904. Logan's were 2-cylinder air-cooled and water-cooled touring cars before standardizing with a 4-cylinder air-cooled car in 1906.

In 1907 a runabout model called the Blue Streak semi-racer was introduced with a 24-hp engine. This sold for $1,750, ().  A truck producer along with automobiles, a new company was formed to concentrate on truck manufacturing in 1908. Gramm trucks built up to 1940.

Advertisements
In 1907 Benjamin Gramm sued Premier Motor Manufacturing Company for infringement on the Logan slogan of "That Car of Quality". He was awarded priority of claim.

Tankeng Dam. The Tankeng Dam is a concrete-face rock-fill embankment dam on the Ou River located  west of Qingtian, Zhejiang Province, China. The main purpose of the dam is hydroelectric power generation but it also provides for flood control, irrigation, and tourism. The  tall dam creates a reservoir with a maximum capacity of . The power station contains 3 x 200 MW Francis turbine-generators for a total installed capacity of 600 MW. The dam was planned beginning in the early 1980s and approved in May 2003. Construction on the dam began that same year and in April 2008, the dam began to impound the river. On 15 August 2008, the first generator became operational, the second on 12 January 2009 and the third on 10 July 2009.

During construction, ten towns and eighty villages were submerged and over fifty thousand people were relocated.

Hamble River H.L.1 Seaplane. 

The Hamble River H.L.1 Seaplane was a British pusher biplane seaplane designed by Frank Murphy and built by Hamble River, Luke & Co Limited at Southampton.

The H.L.1 was exhibited uncompleted at the exhibition at Olympia in February 1914 fitted with a  NAG C.II engine. It was ordered by the British Admiralty to be fitted with a  Gnome engine and issued with serial number 105. The H.B.1 was launched in May 1914 but partly sank and was damaged due to being unbalanced.  It was repaired and fitted with pontoon-floats and tested by Eric Gordon England without much success. It was not accepted by the Navy and was sold at auction in May 1915 for £30.

Asymptotic decider. In scientific visualization the asymptotic decider is an algorithm developed by Nielson and Hamann in 1991 that creates isosurfaces from a given scalar field. It was proposed as an improvement to the marching cubes algorithm, which can produce some "bad" topology, but can also be considered an algorithm in its own right.

Principle 
The algorithm first divides the scalar field into uniform cubes. It draws topologically correct contours on the sides (interface) of the cubes. These contours can then be connected to polygons and triangulated. The triangles of all cubes form the isosurfaces and are thus the output of the algorithm. Sometimes there is more than one way to connect adjacent constructs. This algorithm describes a method for resolving these ambiguous configurations in a consistent manner.

Ambiguous cases often occur if diagonally opposing points are found on the same side of the isoline, but on a different side to the other points in the square (for 2D systems) or cube (for 3D systems). In a 2D case this means that there are two possibilities. If we suppose that we mark the corners as positive if their value is greater than that of the isoline, or negative if it is less, then either the positive corners are separated by two isolines, or the positive corners are in the main section of the square and the negative corners are separated by two isolines. The correct situation depends on the value at the asymptote of the isolines. Isolines are hyperbolae which can be described using the following formula:

where  is the normalised distance in the square from the left-hand side, and  is the normalised distance in the square from the bottom. The values  and  are therefore the coordinates of the asymptotes, and  is the value at the position . This point ought to belong to the section which contains two corners. Therefore, if  is greater than the value of the isoline the positive corners are in the main section of the square and the negative corners are separated by two isolines, and if  is less than the value of isoline the negative corners are in the main section of the square and the positive corners are separated by two isolines. A similar solution is used the 3D version.

Burgess Gunbus. 

The Burgess Type O Gunbus was an American pusher biplane fighter designed and built by the Burgess Company at Marblehead, Massachusetts.

A total of 36 Type Os (also known as the Burgess Gunbus), powered by a single 140 hp (104 kW) Sturtevant engine, was ordered by the British Admiralty in 1915 for use by the Royal Naval Air Service (RNAS). Built in the United States they were shipped to Hendon Aerodrome for erection. The first aircraft flew from Hendon on 26 August 1915 and some of first aircraft were used for training at Hendon and Eastchurch but most went into storage, the last six were not even unpacked. All were removed from the inventory in 1916.

Short S.81. 

The Short S.81 was an experimental British gun-carrying pusher biplane seaplane, ordered from Short Brothers by the British Admiralty in 1913 for use by the Royal Naval Air Service.

The seaplane, manufacturers serial number S.81, was built at Eastchurch and allocated the military serial number 126. S.81 was delivered to Calshot on 25 May 1914 and accepted by the Navy on 2 June 1914. It had three-bay wings with overhanging upper wings, and was powered by a 160 hp (119 kW) Gnome rotary engine. It was first fitted with a 1½ pounder (37 mm) semi-automatic Vickers quick-firing gun in July 1914. Tests with this gun showed that recoil was severe, with claims that firing the gun would induce a stall. It was fitted with a number of different guns for trials, testing a six-pounder (57 mm) Davis gun (an early recoilless gun) in 1915. In 1915 it had a dynamo and searchlight fitted. No longer needed for trials, it was deleted from the inventory in October 1915.

Bitubale. A Bitubale is baled asphalt, in cold form, wrapped in white plastic or in asphalt-based film. Invented by Singapore-based Eastern Petroleum Group, Bitubale is a green technology innovation for the global bitumen (asphalt) transport supply chain. Bitubales are produced in specially designed plants for cooling, dispensing, encapsulation, and packing of bitumen at its supply source. The technologies support cold-form transport of bitumen with zero waste at the end of its supply chain.

Primary benefits of the Bitubale, over hot-form transported asphalt, are halving of the  emissions across the bitumen transport supply chain, large increases in workplace safety for bitumen/asphalt transport workers, elimination of long-term health risks from bitumen/asphalt fumes for transportation workers, elimination of accidental pollution of environmental assets during asphalt transport, and elimination of polluting bitumen-residue waste in millions of discarded drums in landfills.

Programming the Z80. Programming the Z80 is a seminal computer programming text, written by Rodnay Zaks and first published in 1979 by Sybex. It is designed as both an educational text to teach programming techniques of elementary to intermediate level using assembly language, and as a self-contained reference book. It covers more general concepts, such as information representation and data structures, and describes in detail topics specific to the Zilog Z80 microprocessor, such as its internal hardware organisation and instruction set. The book is considered an indispensable reference guide by many Z80 programmers. It was also published by RadioShack with the title How To Program The Z80. In 1983, Sybex published a companion volume, Z80 Applications written by James W. Coffron.

Electrothermal feedback. In electronics, electrothermal feedback is the interaction of the electric current and the temperature in a device with a temperature-dependent electrical resistance. This interaction arises from Joule heating. 

The temperature-dependence of the electrical resistance is described by the derivative of the resistance with respect to temperature dR/dT. Semiconductors typically exhibit a negative dR/dT. Superconductors exhibit a large positive dR/dT on the superconducting phase transition. Normal (non-superconducting) metals typically exhibit a positive dR/dT that decreases to zero at very low temperatures. 

If a device has a positive dR/dT, an increase in temperature (for example, due to thermal fluctuations or the absorption of a photon) will increase the electrical resistance R. If the device is biased with a constant voltage V, this increase in resistance will decrease the Joule power P = V2/R. The decrease in Joule heating will cause the device to return to its equilibrium temperature. This is known as negative electrothermal feedback, as the change in Joule heating opposes the change in temperature. If the device is instead biased with a constant current I, the Joule power P = I2R will increase if the temperature increases. Thus the Joule heating amplifies a change in temperature, an effect known as positive electrothermal feedback. The situation is reversed for the case of a negative dR/dT.

Electrothermal feedback is important for describing the performance of several types of photodetectors such as the bolometer, the transition edge sensor, and the superconducting nanowire single-photon detector.
