Saint-Alban generating station-2. The Saint-Alban-2 power station is an old hydroelectric power station located on the Sainte-Anne River at the level of the Sainte-Anne River Gorges in Saint-Alban in province of Quebec (Canada). It was built between 1925 and 1927 to replace the Saint-Alban-2 power station, which was destroyed by a flood in 1924. It was in use until 1984. It was built at the start of the 2000s to be included in the Portneuf Regional Natural Park.
The power station, the balance chimney, the penstock as well as the dam were cited as heritage building in 2002 by the municipality of Saint-Alban.

History 

The Saint-Alban-1 power station was built between 1911 and 1917 by the Portneuf Hydraulic Company. In 1924, a flood destroyed the powerhouse, causing the bankruptcy of the company. A new power plant was built by the Portneuf Power Company, a subsidiary of the Shawinigan Water & Power Company between 1915 and 1927. The new power plant incorporates elements of the old power plant, including the arch dam . She built new structures, including a power plant further from the falls, a penstock and a balance chimney.

In 1963, following the nationalization of electricity, the power plant passed into the hands of Hydro-Québec. It was closed in 1984. A new powerhouse was built at the new dam in 1996 by Algonquin Power Fund. In the early 2000s, the site of the power station was set up to accommodate one of the sectors of the Portneuf Regional Natural Park. The Saint-Alban-2 generating station was cited as a heritage building by the municipality of Saint-Alban on April 2, 2002.

National Motor Vehicle Title Information System. The National Motor Vehicle Title Information System (NMVTIS) is an electronic system that gives valuable information about a vehicle's condition and history. NMVTIS allows consumers to find vehicle information such as title data, most recent odometer reading, history of make and model, and theft records, but not maintenance or repair history or information about manufacturer recalls. It is a software tool maintained by American Association of Motor Vehicle Administrators. It uses databases from state titling agencies, car recyclers, junk and salvage yards, and insurance carriers to produce its reports.

NMVTIS has the participation of at least 48 states. The purpose of NMVTIS is to help in efforts to prevent consumers from fraud, reduce the use of stolen vehicles and protect consumers from unsafe vehicles.

Raad-500. Raad-500 missile (Persian: موشک رعد ۵۰۰) is an Iranian SRBM/Tactical ballistic missile which is equipped with a progressive composite engine that is dubbed as "Zohair (Persian: زهیر)". Raad-500 means "Thunder 500", and it was designed by halving the weight of the previous Iranian missile (Fateh-110) whose body was made from metal; whereas the range of this new Iranian ballistic missile increased two hundred kilometers more than Fateh-110), and its final range is 500 kilometers.

The Raad-500, is significantly shorter than its predecessor (7.61m compared to 8.86m) yet can reportedly reach 500 km. Its warhead is smaller but still powerful, and designed to separate in the early midcourse phase, making it more difficult to detect, track, and intercept than unibody missiles like the Fateh-110, or those with warheads that separate in the terminal phase.

Engine 

This ballistic missile possesses an engine which has been made of carbon fiber composites, and makes the engine shield able to bear pressures up to one hundred bars.

Unveiling 
Raad-500 missile was unveiled on 9 February 2020 in Tehran by the attendance of IRGC's Chief Commander Major General Hossein Salami, and likewise Brigadier General Amir-Ali Hajizadeh, commander of Aerospace Force of the Islamic Revolutionary Guard Corps.

Essential systems analysis. Essential systems analysis was a new methodology for software specification published in 1984 by Stephen M. McMenamin and John F. Palmer for performing structured systems analysis based on the concept of event partitioning.

The essence of a system is "its required behavior independent of the technology used to implement the system". It is an abstract model of what the system must do without describing how it will do it.

The methodology proposed that finding the true requirements for an information system entails the development of an essential model for the system, based on the concepts of a perfect internal technology, composed of:

 a perfect memory, that is infinitely fast and big, and
 a perfect processor, that is infinitely potent and fast.

Edward Yourdon later adapted it to develop modern structured analysis.

The main result was a new and more systematic way to develop the data-flow diagrams, which are the most characteristic tool of structured analysis.

Essential analysis, as adopted in Yourdon's modern structured analysis, was the main software development methodology until object-oriented analysis became mainstream.

SEDSAT-1. SEDSAT-1 (also known as SEDSAT-OSCAR 33) is a U.S. amateur radio satellite built by students and developed at the University of Alabama in Huntsville (UAH). 

The microsatellite bears the name of one of its sponsoring organizations, the Students for the Exploration and Development of Space (SEDS). It was launched into a low Earth orbit on October 24, 1998 as a Secondary payload with the Deep Space 1 spacecraft using a Delta II rocket at Cape Canaveral Air Force Station, Florida, USA.

History 
The satellite was to be built by the partnership between NASA's Marshall Space Flight Center and UAH with the primary objective of testing a newly developed small expendable deployer system developed for NASA's Space Shuttle, while allowing the students to add instrumentation to complete secondary missions after the primary data regarding the deployer's tether system had been captured. After the Tethered Satellite System (TSS-1R) experienced a failure resulting in the ignition of a strong electrical discharge shortly after being deployed from the Space Shuttle Columbia in 1996, the small expendable deployer system was subject to a Space Shuttle safety review that resulted in extensive design and requirements changes. As a result, SEDSAT-1 became a free-flying secondary payload on the Delta II, after securing sponsorship from other governmental and commercial partners.

Mission 
The satellite was intended to have a novel link to the internet that would allow amateur radio operators from around the globe to request and receive imagery from the satellite anytime it flew overhead. To this end, the satellite carries two cameras as part of the SEASIS (SEDS, earth, atmosphere, and space imaging system) instrument. SEDSAT-1 also includes instruments which monitor battery performance management and control. After launch, telemetry data was received at the satellite's university led mission control center at the University of Arizona in Tucson, AZ. However, an uplink could never be established and no photographic data could be received from the SEASIS instrument. The telemetry data received from the satellite did allow for some of the battery control experiments to be received, and as of 2013 the satellite is still active.

Frequency
 Downlink: 437.91 MHz
 Mode: 9600 bps FSK

USCGC Edgar Culbertson. USCGC Edgar Culbertson (WPC-1137) is the United States Coast Guard's 37th  cutter, and the second of three to be homeported in Galveston, Texas.

Design

Like her sister ships, Edgar Culbertson is designed to perform search and rescue missions, port security, and the interception of smugglers.  She is armed with a remotely-controlled, gyro-stabilized 25 mm autocannon, four crew served M2 Browning machine guns, and light arms. She is equipped with a stern launching ramp, that allows her to launch or retrieve a water-jet propelled high-speed auxiliary boat, without first coming to a stop.  Her high-speed boat has over-the-horizon capability, and is useful for inspecting other vessels, and deploying boarding parties.

The crew's drinking water needs are met through a desalination unit.  The crew mess is equipped with a television with satellite reception.

Operational career

Edgar Culbertson was delivered to the Coast Guard, for her acceptance trials, in Key West, on February 6, 2020. She arrived at her homeport of Galveston, Texas on March 23, 2020. Edgar Culbertson was commissioned in Galveston on June 11, 2020.

Namesake

In 2010, Charles "Skip" W. Bowen, who was then the United States Coast Guard's most senior non-commissioned officer, proposed that all 58 cutters in the Sentinel class should be named after enlisted sailors in the Coast Guard, or one of its precursor services, who were recognized for their heroism.  The Coast Guard chose Edgar Culbertson as the namesake of the 37th cutter.  Culbertson and two other Coast Guard sailors saw three teenage boys at the end of a long pier, on Lake Superior, when a storm had whipped up  waves.  They saw a wave wash one boy off the pier, and saw the other boys pinned by the extremity of the weather.  Culbertson and his comrades ventured out onto the pier to rescue the boys, and Culbertson himself was washed away.

L-W-F Model H Owl. The L-W-F Model H Owl was a large American twin-boom trimotor biplane designed and built by LWF Engineering as a mail plane in 1920, but after being rejected for that role, the single prototype was sold to the United States Army Air Service for evaluation as a bomber but failed to secure any orders.

Design and development
It had a center nacelle with room for three crew members suspended on struts between the wings and flanked on either side by similarly braced tail booms. All three fuselages had a Liberty L-12  engine in the nose, and were fabricated from laminated wood in the same manner as had been used in prior LWF fuselage designs, with three thin layers of wood laid at an angle to each other and separated with fabric. 
The four bay biplane wings were fitted with ailerons on both upper and lower wings.
It had a biplane horizontal stabilizer with three rudders, and ailerons on all four wings. No fin was provided for the center rudder. All controls were given generous aerodynamic counterbalances to reduce control forces. The initial six-wheel undercarriage was later modified to four-wheels, and the radiator for the center engine was moved from in front of the pilot to between the engine and the propeller.

Operational history

The Owl was first flown by Ernest Harmon from Mitchel Field, on Long Island, New York, on 22 May 1920. 

Although built for night air mail service (hence being named Owl), it failed to interest the Post Office.

Between 1921 and 1922, the United States Army Air Service evaluated it as a bomber at Langley Field in Virginia when it was allocated Army Air Service serial number 64012, however its performance was described as “adequate but not impressive.”
General Billy Mitchell planned to evaluate the design during the bombing tests to sink the   and the  in September 1923, but it does not appear that this actually occurred. The sole prototype was scrapped in 1923. Two prototypes of the XNBS-2, a scaled-down twin-engine derivative of the Owl, were ordered in 1923, but this order was cancelled before construction began.

Variants
Model H Owl biplane mailplane/bomber, one built.
NBS-2 Scaled down twin-engined version. Order for two cancelled and none built.

Bengbu Rail Transit. Bengbu Rail Transit () is a rapid transit monorail system and a tram system under construction and planned in Bengbu, Anhui, China. It will connect the urban area of Bengbu with Huaiyuan and Fengyang counties, which are under Bengbu and Chuzhou's administration, respectively. According to the plan, it will be constructed in three phases. Once completed it will have a total length of  on 6 lines. In 2020, the draft of the standard of the tram was published.

History
In March 2014, the Bengbu City Planning and Design Institute began to compile the “Bengbu City Rail Transit Network Plan”. After surveying households and major hub areas, the general direction of the rail transit road network was determined. In August 2015, the plan passed the technical review of the expert group. In March 2016, the executive meeting of the Bengbu City Government formally reviewed and approved the plan. According to the plan, Bengbu Rail Transit will be constructed in three phases. In the initial stage, the construction of Line 1 and Line 2 will form a "Z" -shaped main development axis. In the development stage, a radial track network was formed by constructing extensions of Line 1 and Lines 3 and 4. In the improvement stage, a more complete rail transit network of "grid + radiation" will be formed by constructing extension lines 1, 4 and 5 and 6. Construction begun on an starter section of Line 2 in 2018. In 2020, Bengbu add the plan of the tram.
