Bridgestone Picnica. The Bridgestone Picnica (Japanese: Burijisuton Pikunika: ブリヂストン 「ピクニカ」) line of collapsible bikes, some models featuring belt-drives, were introduced in the early 1980s and carried in the Bridgestone Cycle USA catalogs from 1985 through 1990. It weighs 29 pounds, and belt-drive models use a tooth-belt drive like auto timing belts and Harley-Davidson drive belts, along with a novel two-part chainring that increases belt tension with increasing load. In April 1987, Popular Mechanics described Bridgestone's Beltrex system as follows: "Unlike the belt-drive motorcycles, which can slide the rear wheel back to keep the belt taut, the Beltrex uses a floating pulley that's cogged to the drive gear. Tension on the pedal cranks drives the floating pulley forward, taking up belt slack and preventing tooth slippage."

The Picnica is a folding bicycle, and part of the appeal of the belt drive is cleanliness. It is a small wheel bicycle, so belt tension may be less than on a bicycle with standard-size wheels. 

The folding mechanism is extremely simple, which accounts for the fact that the Picnica was marketed as the "One-touch Picnica" (Japanese: ワンタッチピクニカ). In a review, the Picnica folding mechanism was described as a "case of the frame collapsing backwards on itself, with the handlebars and seat post falling to the top of the rear wheel. To this end, the main part of the frame is a quadrilateral with a pivot at each corner, and a rear triangle made collapsible by hinged seat stays. It's those seat stays that hold everything in place. In the riding position they're straight and rigid, as on any bike. The upper part of each seat stay is locked in a retaining channel by spring pressure; squeeze the upper seat stays inwards and they pop out of their channels, and the hinge 'unlocks'. The upper and lower seat stays then fold over as the main frame folds – the whole bike collapses under its own weight."

The Picnica was apparently commercially successful, but was offered mainly in Japan, where it sold for around 35 000 Japanese yen. The belt-drive version retailed for 45 000 yen.

Karl Brill. Karl Friedrich Brill was an American football player.  He played at the tackle position for the Harvard Crimson football team in 1904 and 1905 and was selected as a first-team All-American in 1905.  As a sophomore in December 1905, Brill announced that he would not continue playing football.  He said, "I came to Harvard to get a degree as a mining engineer.  For the last two years 'Varsity football has played havoc with my studies.  Already I have been forced to drop work in my freshman and sophomore years.  If I play football again it means that I shall fail to get my degree in four years, and I cannot afford a fifth.  It's either play football and fail to get a degree or abandon the gridiron and get a degree."  In addition to the toll the game had taken on his studies, Bill denounced football on moral grounds, stating that the human body was not meant to withstand the strain that football demands and adding, "I don't believe the game is right.  I dislike it on moral grounds.  It is a mere gladiatorial combat.  It is brutal throughout."

Brill's family lost its wealth in a financial collapse, and Brill thereafter worked his way through school as a waiter, janitor, and steel mill worker. After receiving an A.B. from Harvard in 1908, Brill returned in 1910 to pursue a Bachelor of Science, also developing a system of minimalist dieting that he believed would allow him to live 125 years. The 1918 Harvard Alumni Bulletin reported that Brill was a captain of engineering stationed at Camp Humphreys in Virginia.

Strouse, Adler Company Corset Factory. The Strouse, Adler Company Corset Factory is a historic factory complex at 78-84 Olive Street in New Haven, Connecticut.  Developed between 1876 and 1923, it was the largest and oldest of the city's several corset manufacturers, and remained in continuous operation for that purpose until 1998.  The complex was listed on the National Register of Historic Places in 2002.  It has since been converted into residential use.

Description and history
The former Strouse, Adler factory is located east of downtown New Haven, at the corner of Olive and Court Streets in the city's industrial Wooster Square district.  The factory consists of a large number of interconnected brick buildings, ranging in height from one to four stories.  The oldest buildings in the complex have Italianate styling typical of mill construction of the 1860s and 1870s, while expansions in the early 20th century exhibit more neo-Classical styling.  The overall form is one of a rectangle with several outward projections at the corners, and a central courtyard that has partial infill construction.

The business that became Strouse, Adler was founded in 1861 as J.H. Smith and Company, and was the nation's first manufacturer of corsets.  The business was purchased the following year by Isaac Strouse, who took on Max Adler, a local dry goods retailer, as a partner.  The company adopted the name Strouse, Adler in 1899 and was incorporated in 1927.  The company experienced rapid growth in its early years, moving several times before moving into the older portions of this complex in 1876.  It had previously been occupied by the Winchester Shirt Company.  The company was in the vanguard of the rise in the popularity of corsets, as well as the rise of New Haven as nation's largest producer of the garment by the 1890s.  The company remained financially successful through most of the 20th century, despite a decline in popularity of corsets, by introducing lighter-weight fabrics and materials, and manufacturing other types of foundation garments.  It was acquired in 1998 by Sara Lee, and this plant was shuttered.

AAI Penetrator. The American Aircraft International Penetrator was a military helicopter prototype conceived in 1990 as a gunship conversion of the Bell UH-1 Iroquois, aimed at ground insertion, close support and counter-insurgency roles.

Design and development
A single prototype was built in 1991 but the manufacturer never won any contracts for production. It was first designed by the American Aircraft Corporation (AAC) and was marketed by a separate company, American Aircraft International (AAI).

The stated goal of the project was to convert existing Vietnam-era UH-1 airframes to upgrade them with modern armor and weapons systems, particularly targeting third-world militaries with aging fleets. This conversion could be performed at a fraction of the cost, much faster than ordering new aircraft.  The Penetrator required a crew of four (pilot, forward weapons officer, and two rear-facing weapons operators) and could carry six to eight additional passengers.

Operational history
The prototype aircraft was overhauled by Robert Laura and flying as of 2004.

Route panorama. Route panorama is a continuous 2D image that includes all the scenes visible from a route, as it first appeared in Zheng and Tsuji's work of panoramic views in 1990.

Overview
Different from a local panorama at a static viewpoint, a digital route panorama is constructed from partial views at consecutive viewpoints along a path. A general approach to obtain such a complete route panorama is to use a line camera or slit camera mounted on a vehicle moving along the path smoothly. The camera scans temporal scenes in the side direction of the path and connect them to the spatial image. This is realized by a program that processes temporal image data or video data in a computer. The route panorama can extend to a long distance for indexing scenes and navigation on the Internet. The long image can further be transmitted to and be scrolled on computer screens or handheld devices as moving panorama for access of geospatial locations, navigation, georeferencing, etc.

Mathematically, the route panorama employs a parallel-and-perspective projection  that is a continuous and extreme case of multi-perspective view to pixel lines. It may have the aspect ratio of an object different from what a normal perspective projection generates. In addition, a video camcorder is used to produce the route panorama by taking only one pixel line in the video frame at a time with the auto-exposure function of the camcorder and shaking removal function using the inter-frame matching.

If the depth of scenes from the path has a dominant layer, a route panorama can also be created on that layer by stitching discrete photos consecutively taken along the path  using Photomontage. Under the same circumstance, a dynamic slit selected in the video frame can generate a route panorama with less shape distortion.

Molybdenum(II) acetate. Molybdenum(II) acetate is a coordination compound with the formula Mo2(O2CCH3)4. It is a yellow, diamagnetic, air-stable solid that is slightly soluble in organic solvents. Molybdenum(II) acetate is an iconic example of a compound with a metal-metal quadruple bond.

Structure
Like several other transition metal carboxylate complexes, Mo2(O2CCH3)4 adopts a Chinese lantern structure. Each Mo(II) center in Mo2(O2CCH3)4 has four d valence electrons. These eight d-electrons form one σ, two π bonds, and one δ bond, creating a bonding electron configuration of σ2π4δ2. Each of these bonds are formed by the overlapping of pairs of d orbitals. The four acetate groups bridge the two metal centers. The Mo-O bond between each Mo(II) center and O atom from acetate has a distance of 2.119 Å, and the Mo-Mo distance between the two metal centers is 2.0934 Å.

Preparation
Mo2(O2CCH3)4 is prepared by treating molybdenum hexacarbonyl (Mo(CO)6) with acetic acid. The process strips CO ligands from the hexacarbonyl and results in the oxidation of Mo(0) to Mo(II).

2 Mo(CO)6 + 4 HO2CCH3   →   Mo2(O2CCH3)4  +  12 CO  +  2 H2
Trinuclear clusters are byproducts.

The reaction of HO2CCH3 and Mo(CO)6 was first investigated by Bannister et al. in 1960. At the time, quadruple metal-metal bonds had not yet been discovered, so these authors proposed that Mo(O2CCH3)2 was tetrahedral. This perspective changed with Mason's characterization.

Applications
Mo2(O2CCH3)4 is generally used as an intermediate compound in a process to form other quadruply bonded molybdenum compounds. The acetate ligands can be replaced to give new compounds such as [Mo2Cl8]4− and Mo2Cl4[P(C4H9)3]4.

Andal Aerotropolis. Sujalaam Skycity, popularly known as Durgapur Aerotropolis is India's first aerotropolis, located at Andal, Durgapur, Andal, in the industrial city of Durgapur in the Paschim Bardhaman district of West Bengal. It is also the first greenfield aerotropolis, developed around the Kazi Nazrul Islam Airport. It has been developed in association with Singapore's Changi Airports International (CAI) and constructed by Bengal Aerotropolis Projects Limited (BAPL). The airport city is constructed around an old airfield RAF Station Andal and used by the RAF in Andal, and also by the USAAF during World War II.

Formation
On 7 September 2007, the Union Civil Aviation Ministry and the West Bengal government announced plans to set up a new airport – along with a township, IT and logistics hub – at Durgapur. Marking the start of the Aerotropolis Project in Andal, the Andal Aerotropolis Project is spread over approximately  in the Asansol Durgapur Planning Area (ADPA) of Paschim Bardhaman district in West Bengal. Bestowed with premium facilities and unparalleled opportunities in the fields of power-intensive industries, mining, iron and steel, metalwork, engineering, petrochemicals, Information Technology (IT) and telecommunications, ADPA had proved to be an ideal destination for investors. BAPL completed most of its legal procedures, receiving the In-Principal Clearance from the Ministry of Civil Aviation as well as getting the Land Use Development Control Plan (LUDCP) approved by Asansol Durgapur Development Authority (ADDA). It entered into a Technical Services Agreement with Changi Airports India Pte Ltd, Singapore. In Paschim Bardhaman district both Asansol and Durgapur have airstrips for the landing of small planes at Burnpur and Bijra respectively. Also, there is a military airfield at Panagarh in Durgapur subdivision is under Indian Air Force.

The city
Andal Aerotropolis has 493 acre of integrated Township, 472 acres of IT Park, logistics hub and industrial area and 258 acres of institutional area. Narayana Schools have an operating school on the premises. Moreover, a logistics hub of Spectrum Logistics has been set up and is operational (used by Asian Paints). Another company Ardex Endura, which is a ceramic factory, have their operations in the aerotropolis. Keventer Agro has one of its operational unit in the Sujalaam Skycity. Fortune group of hotels has announced its intention to start a four-star hotel like the one in City Centre. Mission hospital is also set to construct its unit there. Lemon tree Hotels have agreed to set up an 80 roomed mid priced luxury hotel in the Sujalaam Skycity.

Aircraft Research BT-11. The Aircraft Research XBT-11 was to have been a basic trainer constructed by the Aircraft Research Corporation (formerly the Vidal Research Corporation) of Bendix, New Jersey, by molding "Weldwood", a "plastic" plywood composite material made of heat and pressure-processed phenol phenol-formaldehyde resins and wood similar to the Duramold process. The Duramold and Haskelite processes were first developed in 1937, followed by Eugene L. Vidal's Weldwood in 1938. A production contract, proposed in 1940, was cancelled before any were built.

Stochastic roadmap simulation. For robot control, Stochastic roadmap simulation is inspired by probabilistic roadmap methods (PRM) developed for robot motion planning. 

The main idea of these methods is to capture the connectivity of a geometrically complex high-dimensional space by constructing a graph of local paths connecting points randomly sampled from that space. A roadmap G = (V,E) is a directed graph. Each vertex v is a randomly sampled conformation in C. Each (directed) edge from vertex vi to vertex vj carries a weight Pij , which represents the probability that the molecule will move to conformation vj , given that it is currently at vi. The probability Pij is 0 if there is no edge from vi to vj. Otherwise, it depends on the energy difference between conformations. 

Stochastic roadmap simulation is used to explore the kinetics of molecular motion by simultaneously examining multiple pathways in the roadmap. Ensemble properties of molecular motion (e.g., probability of folding (PFold), escape time in ligand-protein binding) is computed efficiently and accurately with stochastic roadmap simulation. PFold values are computed using the first step analysis of Markov chain theory.

Richard Harbert Smith. Richard Harbert Smith (15 January 1894, Dillsboro, Indiana – 6 July 1957, Alexandria, Virginia) was a professor and researcher of aeronautical engineering at the Massachusetts Institute of Technology (MIT), from 1929 to 1945.

His academic education was developed at the Moores Hill College (BS, 1915), Indiana (today, University of Evansville); the Massachusetts Institute of Technology (SB, 1918), Cambridge (Greater Boston), Massachusetts; and the Johns Hopkins University (MA, 1928; PhD, 1929), Baltimore, Maryland.

After World War I, Prof. Smith worked as an assistant at the United States Naval Research Laboratory.  In 1929, he was an associate physicist at the Navy's laboratory when he was hired by the Massachusetts Institute of Technology as an associate professor of aeronautical engineering, being promoted to full professor in 1931.

For many years, he was Dr. Jerome Clarke Hunsaker's assistant administrator for aeronautical engineering at MIT.

During the World War II period, Prof. Smith coordinated the MIT Civilian Pilot Training Program and was also instructor for several classes of female engineering trainees for the Curtiss company.

In 1945, he left MIT to go to Brazil, hired by the Brazilian government, in a venture led by Casimiro Montenegro Filho, then lieutenant-colonel of the Brazilian Air Force, to establish an institute of aeronautics, the Instituto Tecnológico de Aeronáutica (Aeronautical Technology Institute), of which he became the first rector. This was an outstanding contribution to the scientific and technological education in Brazil.
