Humphrey cycle. The Humphrey cycle is the thermodynamic cycle occurring detonation engines such as rotating detonation engines,  the pulse detonation engines, and pulse compression detonation systems. It may be considered to be a modification of the Brayton cycle in which the constant-pressure heat addition process of the Brayton cycle is replaced by a constant-volume (isochoric process) heat addition process.
It is a form of pressure gain combustion.

Hence, the ideal Humphrey cycle consists of 4 processes:

Reversible, adiabatic (isentropic) compression of the incoming gas. During this step incoming gas is compressed, usually by turbomachinery. Stagnation pressure and temperature increase because of the work done on the gas by the compressor. Entropy is unchanged. Static pressure and density of the gas increase.
Constant-volume heat addition. In this step, heat is added while the gas is kept at constant volume. In most cases, Humphrey-cycle engines are considered open cycles (meaning that air flows through continuously) which makes it difficult to have a "constant volume" during the addition of heat. Hence, instead of the flame front moving subsonically (deflagration, which is what takes place in Brayton cycle (constant pressure heat addition) engines), the combustion mode is detonative (meaning the flame travels faster than the local speed of sound). In being detonative, the heat addition happens only for a small sector volume of premixture (in a combustor annulus) at a constant volume, while the remaining sections refill the chamber with fresh incoming premixture. This method allows for continuous flow in the system while at the same time achieving the pseudo constant volume requirement for the heat addition process. 
Reversible, adiabatic (isentropic) expansion of the gas. During this step incoming gas is expanded, usually by turbomachinery. Stagnation pressure and temperature decrease because of the work extracted from the gas by the turbine. Entropy is unchanged. Static pressure and density of the gas decrease.
Constant-pressure heat rejection. In this step, heat is removed from the working fluid while the fluid remains at constant pressure. In open-cycle engines this process usually represents expulsion of the gas from the engine, where it quickly equalizes to ambient pressure and slowly loses heat to the atmosphere, which is considered to be an infinitely large reservoir for heat storage, with constant pressure and temperature.

Craftsmanship Museum. The Miniature Engineering Craftsmanship Museum (MECM), also known as the Craftmanship Museum, is an American museum in Carlsbad, California, that collects and displays unique carefully crafted objects of metal and wood. It is sponsored by The Joe Martin Foundation for Exceptional Craftsmanship.

Collection 
The collection includes approximately 500 working miniature engines as well as models of aircraft, automobiles, and other objects.  Especially notable are a 1/6 scale model of a 1932 Duesenberg and several aluminum cutaway World War II fighter models.  A Norden bombsight is displayed in the museum's collection.

1932 SJ Duesenberg 
Louse Chenot constructed a 1/6-scale model of a 1932 SJ Duesenberg. Construction required about 15,000 hours. The engine runs on gasoline. Doors close with two clicks, outside and inside handles operate independently. The model is fully operational, an automobile in miniature.

Machine shop
The museum houses a precision machine shop staffed by volunteer master toolmakers.  The museum's toolmakers work collaboratively with craftsmen throughout the world building miniature projects.  They clean, restore, repair and maintain the objects donated or loaned to the museum.

Exhibits

History
The Craftsmanship Museum first opened in 1996 as an online museum by Joe Martin, owner of the Sherline Company. In 2006, Joe opened a physical museum at the Sherline factory in Vista, California. Within 4 years, the museum outgrew their factory home and Joe decided to create the Joe Martin foundation to purchase a 16,000 square foot building in the Raceway industrial park as a permanent home for the Museum in Carlsbad, just a couple miles from the Sherline factory. Over the years the Museum has expanded its collection of exhibits to include hundreds of working models of all types of miniature machines, engines, architecture, automobiles, and airplanes as well as one-off unique articles of miniature engineering craftsmanship such as a 0.010” diameter bolt with matching nut.

VM/386. VM/386 is a multitasking Multi-user environment or 'control program' that took early advantage of the capabilities of Intel's 386 processor. By utilizing Virtual 8086 mode, users were able to run their existing text-based and graphical DOS software in safely separate environments. The system offered a high degree of control, with the ability to set memory limits, CPU usage and scheduling parameters, device assignments, and interrupt priorities through a virtual machine manager menu. Unique CONFIG.SYS and AUTOEXEC.BAT files could be configured for each application, and even different DOS versions. In 1991 the vendor announced intentions to support DPMI 1.0 in VM/386.

Overview
VM/386 had initially been developed by Softguard Systems, a producer of copy-protection software, with plans to include features like non-DOS system support, but financial constraints forced its sale to Intelligent Graphics Corporation (IGC), which launched the product in 1987. It won a PC Magazine award for technical excellence in 1988. The company also introduced a multi-user version, which allowed a number of serial terminals and even graphical systems to be connected to a single 386 computer. Current versions of the software have built on the multi-user support, and can handle tens of users in a networked environment with Windows 3.11 support, access controls, virtual memory and device sharing, among other features.

A version of the software designed to cooperate with Unix was bundled with Everex Systems workstations. The system now sees use mainly in vertical applications like point-of-sale systems, where its ability to run reliably on cheap, reliable hardware outweigh any gains from newer operating systems that are more complex and less reliable.

Early competition included DESQview 386, Sunny Hill Software's Omniview, StarPath Systems' Vmos/3, and Windows/386 2.01. As the target market shifted away from single-user systems to multiple-user setups with many serial terminals it began to compete more directly with the likes of Multiuser DOS and PC-MOS/386.

Oldershaw O-3. The Oldershaw O-3 is an American high-wing, single seat, V-tailed glider that was designed by Vernon Oldershaw. Two examples were constructed as gliders and then both were later converted to motor gliders.

Design and development
The O-3 was designed by Oldershaw as an improved version of the O-2 to complete in the FAI Open Class. As such it had longer and higher aspect ratio wings of  span.

The O-3 first flew in June 1967.  It is constructed of wood, with the nose made from fibreglass. Its wing employs a Wortmann 61-184 airfoil at the wing root, with a Wortmann 60-126 at the wing tip. The wing is equipped with trailing edge dive brakes. The landing gear is a retractable monowheel.

Both aircraft were constructed as pure gliders and then later motorized with the addition of a twin-cylinder, in-line Yamaha snowmobile engine. The engine is mounted behind the wing spar on a pylon that retracts forward into a bay closed by two doors. The power is transmitted through a belt-drive to a two-bladed propeller. The pylon can be deployed in eight seconds and uses the electric motor from a Ford Thunderbird window winder. The Yamaha powerplant gives a take-off roll of  at an elevation of  and produces a climb rate of .

Operational history
The first O-3 was flown by Oldershaw in several US National contests and Oldershaw completed his distance diamond in the aircraft with a flight of .

Oldershaw's O-3 was listed by the Federal Aviation Administration as destroyed and removed from the register in July 1999. The US Southwest Soaring Museum lists it as being part of their collection.

O-3 serial number 2 was built by Carlton Kibler of Porterville, California and officially registered as a Fry-Kibler O3A Renigade in 1979. In May 2011 the aircraft was still on the FAA registry.

Ecopark (Vietnam). Ecopark is an urban township development on the outskirts of Hanoi, in Hung Yen Province, Vietnam. The township spans 500 hectares with an estimated investment capital of over US$8.2 billion. The entire development, divided into nine construction phases, was expected to complete in an 18-year period.

Development 

Ecopark was developed by Viet Hung Urban Development and Investment J.S.C (VIHAJICO), a joint venture of the following Vietnamese companies:
 AA Construction Architecture Joint Stock Company (AA Corporation)
 ATA Architects Co., Ltd
 Nam Thanh Do Construction Consultants J.S.C
 Thanh Nam Construction and Investment J.S.C
 Duy Nghia Co., Ltd
 Phung Thien Trading Co., Ltd
 Nam Thanh Tourism and Commerce J.S.C
 Bao Tin Trading Co., Ltd.
Construction was completed in 2020.

Opposition from local farmers 
The project has met resistance from about 2000 farmers whose land was repossessed, as in Vietnam all land belongs to the state. There were protests in 2006 and 2006 during construction.  

On April 24, 2012, the project became one of the biggest land confrontations in Vietnam, with police troops facing farmers armed with sticks, rocks and Molotov cocktails. Police fired teargas into the crowds, arrested several protesters, and some villagers were beaten by the police with clubs.

A farmer said "she was initially offered the equivalent of $2.63 per square meter, with the price rising three times to $7.18", while "apartments to be built at Ecopark were offered at a minimum $886 per square meter in a promotion for early buyers in May last year"

Aichi AC-1. 

The Aichi AC-1 was an experimental  nine-cylinder air-cooled radial engine. In 1929, it was used to power the newly designed Aichi AB-2, a catapult-launched reconnaissance seaplane.

The AB-2 with its AC-1 engine is noted for being the first shipboard reconnaissance seaplane and engine combination designed and manufactured entirely in Japan, without foreign assistance. This was a major turning point, not only for Aichi, but for all of the other Japanese aircraft and engine manufacturers, as they no longer need rely on foreign designs.

The engine proved to be a disappointment by not performing as expected. On one test flight, an exhaust fire spread to the airframe and the aircraft was lost, and, soon after, the project ended.

None of these engines survive today, and little is known about them.

Antonov An-50. The Antonov An-50 was a planned Soviet airliner with four turbojets. It was planned by Antonov in the first part of the 1970s. The aircraft was never built.

Antonov made the plans based on the An-24R, but it would have had four turbojets with 14.7 kN thrust each, instead of the two turbojets used earlier. The turbojets were planned to be built together with the undercarriage, under the inner wings. There were no other major changes planned. The plans were complete in 1972, however no aircraft were built.

It was planned to weigh 24600 kg gross, and it would have had a 490 km/h speed at 9400 m altitude.
