Kanjoya. Kanjoya was an enterprise software-as-a-service (SaaS) company that developed natural language processing (NLP) based artificial intelligence to understand, measure, and improve customer and employee experience. Founded in 2006 by Armen Berjikly, the company was acquired by Ultimate Software in 2016.

History 
Headquartered in San Francisco, Kanjoya's vision was to deliver "empathy through technology." The company's core intellectual property was a significant advance in sentiment analysis enabling real-time recognition of over 100 human emotions in written text, with greater accuracy than could be expected of human analysts.

In its development phase, preliminary applications of Kanjoya's technology included measuring the emotional reaction of audiences during political debates, understanding how advertisements made consumers feel, and analyzing consumer sentiment to successfully predict future actions of the Federal Reserve Board.

Eventually, Kanjoya focused product development on understanding employee sentiment in the workplace, through inputs including open-ended survey questions and performance reviews.

Berjikly noted: "The area that we thought we could make the most impact, where people were the least understood, but yet affected the biggest part of their lives was [the] employee world."

Products 
At the time of its acquisition, Kanjoya marketed three software-as-a-service offerings:

 Perception to conduct employee surveys, analyze the results, and distribute results to managers
 Perception for Performance to evaluate, develop, and motivate employees
 Perception for Diversity and Inclusion to diagnose conscious and unconscious bias in the workplace

All solutions focussed on understanding employee's qualitative feedback in addition to more traditional quantitative insights.

Recognitions 
Kanjoya was awarded Awesome New Startup at the 2015 HR Technology Conference; and named Gartner's “Cool Vendor in Human Capital Management, 2016.” In a research partnership with the Federal Reserve Board, it was shown that Kanjoya's technology "outperforms the University of Michigan index of consumer sentiment for predicting macroeconomic series such as output and unemployment."

Haskell organ pipe construction. The Haskell organ pipe construction, sometimes known as "Haskelling" is a method of organ construction used when space does not permit the builder to build a full-length pipe. It consists of a shorter (compared to the full-length pipe) tube nested within another shorter tube. This construction, however, subtly alters the tone of the pipe, causing it to adopt a slightly string-like tone.  The minimum height of a 16-foot pipe using this technique is around 10 feet.

History
This technique was developed and patented by the William E. Haskell in 1910 for Estey, in a series of patents Haskell took out on techniques intended to reduce the length of organ pipes while maintaining their pitch. Haskell created several variations on this design.   This technique was especially used in the Estey Minuette organs, which had 2MP pipe organs in what resembled rather large grand or upright piano cases.

Uses
This technique is far more commonly used on flue pipes than reed pipes.

33DD destroyer. The 33DD (also known as DDR or Destroyer Revolution) was a Japanese destroyer proposed for the Japan Maritime Self-Defense Force. The tentative name of the class, 33 DD, is derived from an estimate that it would be budgeted in the Japanese era of Heisei 33 (2021). However, the fiscal 2021 budget, which was released in 2020, does not include 33 DD, and the plan for the destroyer is not concrete.

Development 
The first concept model of the destroyer was shown in Defense Technology Symposium 2010 by Kawasaki Heavy Industries. The project was also mentioned in the FY2011 defense budget request, only mentioning that research on new integrated antenna system and sonar system for next generation destroyers is to be carried out around 2018. Later a second model was shown in Defense Technology Symposium 2012.

Design 
The destroyer will feature an integrated mast, a Carbon fiber reinforced plastic (CFRP) hull and will have a slightly higher displacement than the Asahi-class destroyer. The CFRP hull reduces the ship's electromagnetic signature and its structural elasticity provides protection against torpedoes and mines. The hull will also be made of high strength stainless steel due to its superior protection from air and underwater explosion compared to high tensile steel. The first model unveiled is described to displace 5400 tons and is very similar in design to the Asahi-class destroyers. The second concept model displaces 5100 tons and features a stealthier design than first. The FCS-3 system and integrated radio wave systems is used to enhance the ship's communication, radar, and electronic warfare capabilities.

Sukhoi T-49. The Sukhoi T-49 was a prototype Soviet fighter aircraft.

Development
The Sukhoi T-49 was a modernized version of the Sukhoi Su-11 with new radar and modified armament. The project was officially launched on August 6, 1957. The maiden flight of the T-49 prototype took place in January 1960, after various rolling tests in October 1959. 

In the development of the T-49, the delta wing, the tail and the cigar-shaped fuselage were taken from the Su-11. The entire fuselage in front of the cockpit has been redesigned to accommodate a more powerful radar. This extended the nose of the aircraft. Since this also gave the plane a larger diameter than the Su-11, it was no longer possible to accommodate the radar antenna in the shock cone of the air inlet. Therefore, lateral air inlets were constructed on both sides of the nose. This also simplified the operation of the radar, since its antenna was now firmly installed in the aircraft nose and the forward and backward movements of the engine shock cone no longer had to be compensated for.

The flight tests with the T-49 were promising but showed that the twin-engined project T-58 had a greater potential. Particularly in relation to the wishes of the PWO regarding the reliability of the engines, the single-engine T-49 did not meet these requirements as well as the T-58. However, the T-49 proved to be a valuable precursor to the T-58, especially in terms of radar and the development of the air intakes. In the air intakes, this helped the T-58 gain a development advantage over the competing design of the Yak-28-64. The T-58 finally developed into a production version under the designation Su-15.

The only prototype of the Sukhoi T-49 was damaged in April 1960. Although repairs were carried out, the aircraft was never flown again and was scrapped.

Horten H.I. The Horten H.I was a German flying wing research glider built by Walter and Reimar Horten in 1933.

Design and development
The first aircraft of the Horten brothers was created with considerable effort in 1933 in their parents' apartment in Bonn. Reimar Horten designed and built the machine and learned to fly it. Flight testing started in July 1933 at the Bonn-Hangelar airport, and Walter Horten, only 20 years old, made the first cautious hops in the aircraft on the end of a bungee cord, resulting in glides of 150 to 300 feet at altitudes of six feet or less. After a few small changes, the H.I had overcome the biggest teething troubles, and the brothers took it to the Wasserkuppe competition the following year.

H.Ib

In 1951, members of the Club de Planeadores Otto Ballod and Reimar Horten built a new version, called the H.Ib, using a more modern section and the control accomplished by elevons located on the outer wings, omitting the inner elevators/flaps. For use as rudders, Schempp-Hirth flaps were installed on the wingtips, also serving as a landing aid when both flaps were activated together.

Operational history

Horten H.I
The H.I was first flown in July 1933 at Bonn-Hangelar airport, initially using bungee cord, then auto-tow, leading to winch launches to . Aero-tow launches were then carried out using a BFW M.23 as tug, to .

Problems with control and stability were discovered, due to the operation of the elevators and ailerons and centre of gravity too far aft. With the flying qualities of the aircraft satisfactory, Walter Horten set off under aero-tow to the 1934 Rhön meeting at the Wasserkuppe, towed by a Klemm L.25. Delayed en route by bad weather, Walter arrived late and also damaged the aircraft on landing. Although unable to participate in the flying contest the H.I was awarded a "Construction" prize of DM600.

Walter remained at the Wasserkuppe with the H.I until the Gliding school Director ordered him to leave and take the H.I with him. A telephone request to Alexander Lippisch for a tug to fly the H.I back to Bonn was unsuccessful, so Walter flew the H.I for one more time, landed successfully, broke up the aircraft and burned the remains.

Horten H.Ib
The H.Ib had good handling characteristics and was flown far into the 1970s by the Club de Planeadores Otto Ballod. At the turn of the millennium, the members of the club restored their long-serving flying-wing to "better than new" condition.

The H.Ib was the only Horten flying wing still airworthy, until the first flight in Germany in 2016 of the newly built H.IV.

Variants

Alphonse Couvreux. Alphonse Couvreux (1820 – July 1890) was a French public works contractor, known for inventing the bucket chain excavator for which he filed a patent in May 1860.

The bucket chain excavator was used to remove great amounts of earth for the construction of railroads and the Suez Canal. The first documented use of the machine on land was in 1859. Couvreux used some of his machines to excavate material for the Ardennes Railroad. About 8 million cubic yards of material was excavated from the Suez Canal by seven of his machines during a portion of its construction from 1863 to 1868. Some of Couvreux's machines were used in the early failed French attempt to build the Panama Canal. The bucket chain excavator is still used in open pit mines and quarries. A scale model of one of his 1859 machines is located in the Museum of Arts and Trades in Paris.
