Advanced Aeromarine Sierra. The Advanced Aeromarine Sierra was an American high-wing, strut-braced, single-seat, glider that was designed and produced by Advanced Aeromarine, as a kit for amateur construction.

Design and development
The Sierra was intended as a lightweight and affordable glider with modest performance that could be launched by ultralight aircraft aerotow, auto-tow, winch-launch or bungee launch. It first flew in March 1991.

The aircraft was made from aluminium tube, fabric and composites. Its  span wing was supported by a lift strut and jury struts. The glide ratio was 25:1 and had a landing roll of . The landing gear was tandem wheels, plus a tail caster. The completion time from the factory kit was rated as 150 hours.

Although very light, with a standard empty weight of , the Sierra did not qualify under the US FAR 103 Ultralight Vehicles regulations as a hang glider, neither was it foot-launchable. Only one prototype had been reported as completed by December 1998.

Operational history
In September 2011 there were no Sierras registered with the US Federal Aviation Administration and it is likely that none exist anymore.

Advanced Aviation Cobra. The Advanced Aviation Cobra was a U.S. ultralight aircraft of extremely minimalist design marketed for homebuilding, developed from the Advanced Aviation Husky. The pilot is seated in an open framework suspended beneath a fabric-covered wing on which the engine (adapted from a snowmobile) and pusher propeller are also mounted. Early Cobras (Model A) had spoilers for roll control, while the Model B had traditional full three-axis control using ailerons. A two-seat training version, known as the King Cobra was also available.

Coping (architecture). Coping (from cope, Latin capa) is the capping or covering of a wall. A splayed or wedge coping is one that slopes in a single direction; a saddle coping slopes to either side of a central high point.

Coping may be made of stone (capstone), brick, clay or terracotta, concrete or cast stone, tile, slate, wood, thatch, or various metals, including aluminum, copper, stainless steel, steel, and zinc. In all cases it should be weathered (have a slanted or curved top surface) to throw off the water.

In Romanesque work, copings appeared plain and flat, and projected over the wall with a throating to form a drip. In later work a steep slope was given to the weathering (mainly on the outer side), and began at the top with an astragal; in the Decorated Gothic style there were two or three sets off; and in the later Perpendicular Gothic these assumed a wavy section, and the coping mouldings continued round the sides, as well as at top and bottom, mitring at the angles, as in many of the colleges at the University of Oxford.

Reflex locomotion. Reflex locomotion, usually referred to as the Vojta method, is a technique for the treatment of physical and mental impairment in humans. It was discovered by Václav Vojta.

Based on studies of treatments for spastic children for muscular disorders in the 1950s, a number of reflex points were identified which can be used to stimulate the human body to crawl and turn. By applying pressure to the appropriate reflex points the major muscle groups in the body are activated, breathing becomes regulated and mental activity increases.

The Vojta method is classified as alternative medicine.

CINT. CINT is a command line C/C++ interpreter that was originally included in the object oriented data analysis package ROOT. Although intended for use with the other faculties of ROOT, CINT can also be used as a standalone addition to another program that requires such an interpreter. In 2013, CERN switched to the Cling C++ interpreter, so CINT is now distributed standalone by the author.

CINT is an interpreted version of C/C++, much in the way BeanShell is an interpreted version of Java. In addition to being a language interpreter, it offers certain Bash-like shell features such as history and tab-completion. To accomplish the latter, it relies heavily on the reflection support built into ROOT.  User classes that follow these interfaces may also take advantage of these features.

The language originally interpreted by CINT was actually something of a hybrid between C and C++, covering about 95% of ANSI C and 85% of C++. The syntax, however, is a bit more forgiving than either language.  For example, the operator -> can be replaced by . with only an optional warning.  In addition, statements on the command line do not need to end with a semi-colon, although this is necessary for statements in macros.

As an alternative to CINT, ROOT also provides Cling which is an REPL application using LLVM's Clang as a C++ JIT compilation environment.

Advanced Aviation Explorer. The Advanced Aviation Explorer is a two-seat ultralight marketed in kit form, for amateur construction. It is a high-wing taildragger aircraft of pusher configuration with tandem seating.

Design and development
The aircraft is a development of the Talon XP which in turn traces its lineage to the Maxair Drifter. The Explorer has been produced by a number of companies and under a variety of names.

The main advance over the Drifter is the Explorer's use of main wing struts and jury struts in place of cable bracing. Like all aircraft in this family they feature excellent visibility, especially from the front seat when the optional fibreglass cockpit pod is removed. As a result, the design is often employed as a camera platform. It can be flown on floats and has been used for banner towing.

Construction is of bolted aluminium tube, with the flying surfaces covered in pre-sewn Dacron envelopes. The kit takes about 150–250 hours to assemble.

The standard engine is the Rotax 582 of , with the four-stroke  Rotax 912 optional.

Specific weight. The specific weight, also known as the unit weight   (symbol , the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material:

Equivalently, it may also be formulated as the product of density, , and gravity acceleration, : 

Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m3), with base units of kgm−2s−2.
A commonly used value is the specific weight of water on Earth at , which is .

Discussion
The density of a material is defined as mass divided by volume, typically expressed in units of kg/m3. 
Unlike density, specific weight is not a fixed property of a material, as it depends on the value of the gravitational acceleration, which varies with location (e.g., Earth's gravity). 
For simplicity, the standard gravity (a constant) is often assumed, usually taken as .

Pressure may also affect values, depending upon the bulk modulus of the material, but generally, at moderate pressures, has a less significant effect than the other factors.

Applications

Fluid mechanics
In fluid mechanics, specific weight represents the force exerted by gravity on a unit volume of a fluid.  For this reason, units are expressed as force per unit volume (e.g., N/m3 or lbf/ft3).  Specific weight can be used as a characteristic property of a fluid.

Soil mechanics
Specific weight is often used as a property of soil to solve earthwork problems.

In soil mechanics, specific weight may refer to:

Civil and mechanical engineering
Specific weight can be used in civil engineering and mechanical engineering to determine the weight of a structure designed to carry certain loads while remaining intact and remaining within limits regarding deformation.

List of Ford factories. The following is a list of current, former, and confirmed future facilities of Ford Motor Company for manufacturing automobiles and other components.  Per regulations, the factory is encoded into each vehicle's VIN as character 11 for North American models, and character 8 for European models.
 
The River Rouge Complex manufactured most of the components of Ford vehicles, starting with the Model T. Much of the production was devoted to compiling "knock-down kits" that were then shipped in wooden crates to Branch Assembly locations across the United States by railroad and assembled locally, using local supplies as necessary. A few of the original Branch Assembly locations still remain while most have been repurposed or have been demolished and the land reused. Knock-down kits were also shipped internationally until the River Rouge approach was duplicated in Europe and Asia.

General Electric LM6000. The General Electric LM6000 is a turboshaft aeroderivative gas turbine engine. The LM6000 is derived from the CF6-80C2 aircraft turbofan. It has additions and modifications designed to make it more suitable for marine propulsion, industrial power generation, and marine power generation use. These include an expanded turbine section to convert thrust into shaft power, supports and struts for mounting on a steel or concrete deck, and reworked controls packages for power generation. It has found wide use including peaking power plants, fast ferries and high speed cargo ship applications.

Design and development

The LM6000 provides  from either end of the low-pressure rotor system, which rotates at 3,600 rpm. This twin spool design with the low pressure turbine operating at 60 Hz, the dominant electrical frequency in North America, eliminates the need for a conventional power turbine. Its high efficiency and installation flexibility make it ideal also for a wide variety of utility power generation and industrial applications, especially peaker and cogeneration plants. 

GE has several option packages for industrial LM6000s, including SPRINT (Spray Inter-Cooled Turbine), water injection (widely known as "NOx water"), STIG (Steam Injected Gas Turbine) technology and DLE (Dry Low Emissions) which utilizes a combustor with premixers to maximize combustion efficiency.   The  SPRINT option is designed to increase efficiency and power of the turbine, while the water injection, STIG and DLE are for reducing emissions. An alternative form of power augmentation is Evaporative Cooling, which is a water fogging system that sprays a fine mist of water into the inlet air before the air filters.   This system is high maintenance and may be replaced by chillers in newer units.  The SPRINT system injects demineralized water into the engine either upstream of the low pressure compressor or between the low pressure and high pressure compressors.  The water injection system injects water into the primary or secondary fuel nozzle inputs, usually on natural gas fired engines.  

The GE LM6000 PC is rated to provide more than 43 MW with a thermal efficiency of around 42% LHV at ISO conditions.  With options, this can be increased to around 50 MW rated power.

Applications
Over 1000 LM6000 gas turbines shipped and over 21 million hours of operation. Applications include power generation for combined cycle or peak power. Other applications include combined heat and power for industrial and independent power producers.
