Circa Reproductions Nieuport. The Circa Reproductions Nieuports are a family of Canadian 7/8 scale World War I sesquiplane aircraft replicas designed by Graham Lee of Lamont, Alberta for amateur construction from plans sold by Lee's company Circa Reproductions. Leading Edge Air Foils of Peyton, Colorado at one time also made construction kits available. Lee's Nieuports were among the earliest First World War replicas available and paved the way for later companies to produce plans and kits for a great variety of warbirds.

The aircraft's design was attributed to "the result of many years of affection for WWI type aircraft and a "too limited" flying budget."

Design and development
The Nieuport 11 was the first design in the family and is a 7/8 (87%) scale version of the original French Nieuport 11 Bebe fighter. The prototype, registered as a Canadian basic ultralight as C-IRCA, first flew in July 1984.

The Nieuport 11 is constructed from 6061-T6 aluminum tubing, supported with 2024-T3 aluminum gussets, held together with blind rivets. At one point welded steel tube fuselages were also available. The wings, tail and fuselage are then covered with doped aircraft fabric. Landing gear is conventional, with  spoked mainwheels with bungee suspension. The original design calls for a tailskid, the same as the World War One original aircraft, but since the skid is impractical on hard surfaced runways, a tailwheel is optional. The engine cowling is a horseshoe shaped semi-circular design.

Recommended engines for the aircraft include the  Rotax 447, the  Rotax 503, Volkswagen air-cooled engines and various Hirth engines. The designer estimated that the Nieuport 11 would take 400 hours to construct.

The aircraft have been described as being "very easy to fly, even by novice pilots."

By 2015 over 1200 sets of plans had been sold.

Operational history
The Nieuport 11 won Grand Champion Light Plane at Oshkosh in 1989 and the Nieuport 12 won Reserve Grand Champion at Oshkosh in 1990.

Variants
Nieuport 11
Single seat 7/8 scale reproduction of the Nieuport 11 fighter of 1916. First flown in July 1984. Kits were available in ultralight and experimental versions to meet United States FAR 103 Ultralight Vehicles and Experimental amateur-built regulations respectively. The ultralight version uses lighter tubing, engine and wheels to save weight.
Nieuport 12
Two seat 7/8 scale reproduction of the Nieuport 12 WWI observation aircraft, first flown in 1989. The designer estimates construction time at 1400 hours. Aircraft has  gross weight. Recommended engines include the  Rotax 582,  Continental A65,  Lycoming O-145 or  Volkswagen air-cooled engine.
Nieuport 17
Single seat 7/8 scale reproduction of the Nieuport 17 WWI fighter aircraft. This variant is similar to the Nieuport 11, but with a  greater wingspan and a completely circular engine cowling. The designer estimates construction time at 400 hours.

Assault boat. An assault boat is a boat used for landing in combat, specifically for inland waters. Their lightweight construction allows for them to be carried by multiple men on foot. They can either be paddled or fitted with an outboard motor for high-speed operation. Some assault boats can be fitted with small firearms such as automatic rifles. Larger assault boats are used in riverine and littoral water where the boat can easily berth in tight spaces and shallow waters. The length of assault boats is usually 5 to 20 meters and they are constructed from rubber, fiberglass, aluminum, or steel.

WWII

U.S. military

Assault boats in the U.S. military during World War II were typically used by Combat Engineer Battalions, whose combat engineers deployed and crewed them.

The Americans deployed two types of assault boats, the "Storm Boat" and the "M2." The "Storm Boat" was an 8-man (6+2 crew) high-speed assault boat with a 55-horsepower outboard motor designed to breach at speed thus allowing the soldiers on board to "storm the shore". The "M2" was a ten-man boat (8+2 crew) that was paddled.

British
The British used two types of assault boat: a "storm boat" and a lower performance canvas boat known as "The Goatley boat".

Overview of the differences between British and American Storm and Assault Boats

Assault Boats

Storm Boats

a. British Storm Boat.
(1) Heavier to carry across the country.
(2) Would carry the heavier load (6-pounders or jeep though the latter a top-heavy load).
(3) Carried ten men but at a lower speed.

b. American Storm Boat.
(1) Carried by 6 men (plus 2 for motor).
(2) Would carry up to 1500 lbs with very little reduction in speed.
(3) Carried 7 men (above crew) at maximum speed.
(4) Was the faster boat; would beach at full speed.

c. Conclusions:
(1) For assault crossing of personnel the U.S. boat carried fewer men but got them across the river and in action much faster.
(2) For cargo carrying, the British boat carried a greater load but at a slower speed.

Thrust1. Thrust1 was a British-designed and built jet-propelled car. The car was designed and built by its driver Richard Noble, who later achieved the land speed record with his car Thrust2.

Thrust1 itself was never intended to be a contender for the record. Noble's plan was for three cars: Thrust1 "to learn the ropes", a second demonstration car to raise interest and the essential large-scale sponsorship, then Thrust3 for an attempt on the record.

Details
The car was powered by a military-surplus Rolls-Royce Derwent engine, as the simplest jet engine available. The particular engine used was a Mk 8 from a Gloster Meteor of around 3,500 pounds thrust. The ladder chassis was also acquired as surplus, from Noble's employers GKN Sankey. The extremely tight project budget was initially funded by Noble selling his own car, a Triumph TR6. The direct costs of the project, estimated afterwards, were at around £1,500, including £1,100 for the TR6 Sponsorship was acquired from a variety of small agreements, including sponsorship-in-kind from the tool manufacturer Black & Decker. Construction began in the garage of Noble's flat in Thames Ditton. By 1975, the car was completed in a lock-up garage at Turnham Green.

The first test run was at RAF St Athan in South Wales. This was little more than a shakedown at low power, and no more than 80 mph. A demonstration run for filming was also made around the circuit at Brands Hatch. Runs were also conducted at RNAY Wroughton near Swindon. By 1977 the team were ready for a high-speed run, planned for the long 10,000 foot runway of RAF Fairford

The first high-speed run was planned for 7 March 1977, the day after Noble's thirty-first birthday. A successful first run was made from a standing start at idle thrust and gradual acceleration, reaching an estimated top speed of 180 mph. The second run was planned to be a drag start, with thrust built up against the brakes and then released. At around 140 mph though, a rear-wheel bearing seized and the car went sideways, then rolled. The triple roll was mostly airborne and the car landed on its side, with relatively little damage. Noble was unhurt. The Derwent engine, and its protruding combustion chambers, took much of the damage. The jetpipe broke loose and at least one combustion chamber was crumpled.

The car never ran again, and the wreckage was sold to a scrap dealer for £175, after parts had been removed to ensure that it could never be run again. Despite the crash, Noble was not disheartened and saw this as the conclusion of the first step of his original plan.

Successor

By October of the same year, an engine had already been acquired for the next project, Thrust2 and this Rolls-Royce Avon was displayed at the London Motorfair to raise interest and sponsorship.

Digital do MaiN. is a Japanese audio engineering company headquartered in Chiyoda, Tokyo, Japan. The company name emphasises symbiosis of analog and digital technologies (implemented, for example, in a volume control subsystem); the logo symbolizes an input pin jack (left square), output pin jack (right square) and an innovative signal processing unit in between.

Technology
Digital do MaiN's power amplifiers use V-FET technology transistors. Initially developed by Nippon Gakki Seizo K.K. in the 1970s (US Patent 4,216,038), the technology was improved, and the 2SK77B transistor was released. As V-FET devices are no longer manufactured, Digital do MaiN builds them itself. Original design and usage of the 2SK77B V-FET transistor give amplifiers characteristics similar to vacuum tube devices and Triode class A amplifiers which feature very high quality of output sound and cancellation of most of the even distortion harmonics, and allow noise distortion to be less than 0.005% and no loss of original harmonics. Digital do MaiN also uses technologies and complementary products from its partners: MSB Technology's (USA) DACs, Cabasse (France) loudspeakers, Denon (Japan) waveform reproduction technology.

Awards
Japanese Audio Excellence Award 2009, Separate Digital Players category (D-1a D/A converter) and Main Amplifiers category (B-1a power amplifier)

Relative growth rate. Relative growth rate (RGR) is growth rate relative to size - that is, a rate of growth per unit time, as a proportion of its size at that moment in time. It is also called the exponential growth rate, or the continuous growth rate.

Rationale
RGR is a concept relevant in cases where the increase in a state variable over time is proportional to the value of that state variable at the beginning of a time period. In terms of differential equations, if  is the current size, and  its growth rate, then relative growth rate is
.
If the RGR is constant, i.e.,
,
a solution to this equation is

Where:
S(t) is the final size at time (t).
S0 is the initial size.
k is the relative growth rate.
A closely related concept is doubling time.

Calculations

In the simplest case of observations at two time points, RGR is calculated using the following equation:

,

where:

 = natural logarithm

 = time one (e.g. in days)

 = time two (e.g. in days)

 = size at time one

 = size at time two

When calculating or discussing relative growth rate, it is important to pay attention to the units of time being considered.

For example, if an initial population of S0 bacteria doubles every twenty minutes, then at time interval  it is given by solving the equation:

where  is the number of twenty-minute intervals that have passed. However, we usually prefer to measure time in hours or minutes, and it is not difficult to change the units of time.  For example, since 1 hour is 3 twenty-minute intervals, the population in one hour is . The hourly growth factor is 8, which means that for every 1 at the beginning of the hour, there are 8 by the end.  Indeed,

where  is measured in hours, and the relative growth rate may be expressed as  or approximately 69% per twenty minutes, and as  or approximately 208% per hour.

RGR of plants
In plant physiology, RGR is widely used to quantify the speed of plant growth. It is part of a set of equations and conceptual models that are commonly referred to as Plant growth analysis, and is further discussed in that section.
