AVIC Lucky Bird. The AVIC Lucky Bird (Chinese: Jixiangniao) is a Chinese ultralight trike, under development by Aviation Industry Corporation of China. The aircraft is envisioned for the police, border patrol, traffic and pollution surveillance, reconnaissance, aerial photography, forest fire patrol and touring roles.

Design and development
The aircraft has been noted as unusual due to its national origin and also being the project of a large state-run aviation company that also produces fighters and jet transport aircraft.

Very little technical data has been released about the Lucky Bird to date. It is known that it features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear with wheel pants and a single engine in pusher configuration. A three-seat version is also being developed.

The aircraft resembles most western-designed trikes. It is made from bolted-together aluminium tubing, with its double surface wing covered in Dacron sailcloth. Its wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is an Austrian-made four cylinder, air and liquid-cooled, four-stroke, dual-ignition  Rotax 912 engine.

J. Reid Shelton. Dr. J. Reid Shelton (January 16, 1911 – December 31, 2007) was a professor of chemistry at Case Western University in Cleveland, Ohio.  He is known for his work on oxidation and antioxidants in rubber, and for his application of laser-Raman spectroscopy to the study of sulfur vulcanization. His research on synthetic rubber was particularly important during World War II, when access to natural rubber in Southeast Asia was cut off by the Japanese, and the new SR made from styrene and butadiene displayed stability problems.

With his students, he undertook fundamental studies of the reactions occurring in the oxidation, degradation, and stabilization of rubber and other polymers with support at various times from Firestone, Goodyear, the U.S. Army Ordnance Research and other government agencies, and the Petroleum Research Fund.

In 1983, Shelton received the ACS Rubber Division's Charles Goodyear Medal.  Shelton mentored another
Charles Goodyear Medalist: Jack L. Koenig.  Koenig won the award in 2000.

Shelton retired in 1977 after 41 years of teaching.

He died December 31, 2007 at the age of 96.

Drawdown chart. Drawdown charts are rectangular pieces of non-fluorescent paper which are used to test a variety of coating properties.  These properties include opacity, spreading rate, penetration, and flow & leveling behavior.  This non-fluorescent material has to be especially rugged in order to maintain its structure and give reliable readings, as the coatings tested are often corrosive or abrasive.
These charts are necessary in the testing of any coating as they give reliable and accurate readings for any type of coating before the coating is applied to the intended material.

Drawdown bars

Drawdown bars are used in collaboration with drawdown charts.  The bars are generally made of stainless steel or aluminum and touch the chart at each end, while the center is slightly raised to a desired height in order to obtain the desired film thickness.  As with the charts, the bars have to be especially resistant to corrosion because of the corrosive nature of some coatings.  There are a multiplicity of more complicated designs including some in which the paint is already in the chart apparatus, but the bar method described above is the most commonly used.

Procedure

Initially the desired coating is applied in a puddle on the drawdown chart.  Then the bar is placed at the top of the chart, and drawn down over the paint in order to spread it evenly along the length of the chart.  Once this evenly spread paint dries, it can be tested for a variety of properties.

Endeavour (supercomputer). Endeavour is a shared memory supercomputer at the NASA Advanced Supercomputing (NAS) Division at NASA Ames Research Center. It was named after the Space Shuttle Endeavour, the last orbiter built during NASA's Space Shuttle Program.

Built in February 2013 as a replacement for the Columbia supercomputer, it consists of two nodes across three SGI UV 2000 racks with 1,536 Intel Xeon E5-4650L “Sandy Bridge” processors for a theoretical processing capability of 32 teraflops. Its global shared-memory environment allows for one processor to access the memory of other processors in the cluster as needed, giving users the ability to run jobs larger and more data-intensive than could be achieved on other NASA systems limited by processor memory. At the time it was installed, Endeavour had more processing power than what remained of Columbia at its decommissioning (approximately 30 teraflops across 40 SGI Altix 4700 racks), but in only ten percent of the physical space.

It is currently one of two systems owned and operated by the NASA Advanced Supercomputing Division, along with Pleiades, NASA's flagship supercomputer based on SGI ICE architecture and several generations of Intel Xeon processors.

Hanriot H.110. The Hanriot H.110 was an unusual pusher configuration, twin boom, single seat fighter aircraft built in France in the early 1930s.  It proved to be slower and less manoeuvrable than its contemporaries and failed to reach production, even as the Hanriot H.115 after receiving a more powerful engine and cannon armament.

Design and development

From 1916 until 1933, the only Hanriot fighter aircraft had been tractor biplanes.  The Hanriot H.110, a twin boom pusher cantilever monoplane was therefore a considerable departure from the past. It was designed to compete in the STAé (Service Technique de l'Aéronautique or Technical Section of Aeronautics) 1930/31 C1 (single seat Chasseur of fighter) programme.

The all-metal H.110 had an open cockpit and engine in a short central nacelle.  It was powered by a  Hispano-Suiza 12Xbrs supercharged upright water-cooled V-12 engine behind the pilot, driving a three-blade pusher propeller. The pilot's headrest was smoothly faired into the engine cowling. There was a circular Chausson radiator in the short nose ahead of the open cockpit, with a variable position central cone to control the airflow.

The wings were built around two spars. The central 25% of their span, between the booms, had constant chord.  Immediately outboard they had a wider chord and beyond were double straight tapered to rounded tips. They carried  almost full-span, narrow-chord Frise ailerons. Forward, the slim, square section and untapered tail booms blended into the wings at about mid-chord, the aft ends carrying a constant-chord tailplane slightly above them. This had rounded tips and a central elevator with a trim tab. A central, single, tall, round-tipped, wire-braced vertical tail was mounted on in it. The H.110 had a fixed, split, conventional undercarriage with each spatted mainwheel on a faired, near vertical shock absorber and a rearward leaning strut together forming a V, laterally braced with an inverted V-strut attached near the under-fuselage centre line.  There was a central tailwheel on a long leg under the fin.

The H.110 began flight testing in April 1933. Tested against its smaller and lighter competitors, it proved slower and less manoeuvrable and was returned to Hanriot for modification. It flew in April 1934 as the H.115, with its HS 12Xbrs engine uprated to , a new four-blade propeller with variable-pitch and a revised nacelle, shortened forward of the cockpit by . A  APX cannon was now housed in a fairing below the nacelle as an alternative to the earlier pair of Chatellerault  machine guns. With its new engine and propeller the H.115 was quicker than the earlier version, with a top speed of . After more modifications over the winter of 1934-5 it returned to Villacoublay in June 1935 and was officially flight tested until mid August, but failed to attract a contract.

Function block diagram. The function block diagram  (FBD) is a graphical language for programmable logic controller design, that can describe the function between input variables and output variables. A function is described as a set of elementary blocks. Input and output variables are connected to blocks by connection lines.

Design
Inputs and outputs of the blocks are wired together with connection lines or links. Single lines may be used to connect two logical points of the diagram:

 An input variable and an input of a block
 An output of a block and an input of another block
 An output of a block and an output variable

The connection is oriented, meaning that the line carries associated data from the left end to the right end.  The left and right ends of the connection line must be of the same type.

Multiple right connection, also called divergence, can be used to broadcast information from its left end to each of its right ends.  All ends of the connection must be of the same type.

Language
Function Block Diagram is one of five languages for logic or control configuration supported by standard IEC 61131-3 for a control system such as a programmable logic controller (PLC) or a Distributed Control System (DCS).  The other supported languages are ladder logic, sequential function chart, structured text, and instruction list.

USA-243. USA-243, also known as WGS-5, is a United States military communications satellite. It was the fifth satellite to be launched as part of the Wideband Global SATCOM program and the second Block II satellite.

Overview 
The WGS system is a system of military communications satellites that use cost-effective methods and technological advances in the communications satellite industry. The WGS system is composed of three principal segments: Space Segment (satellites), Control Segment (operators), and Terminal Segment (users). Each WGS satellite provides service in multiple frequency bands, with the ability to cross-band between the two frequencies on board the satellite. WGS augments other satellites.

In early 2001, a satellite communications industry team led by Boeing Satellite Systems was selected to develop the Wideband Gapfiller Satellite (WGS) system as a successor to the Defense Satellite Communications System (DSCS) series of communications satellites. It is intended to support the U.S. Armed Forces with greater capabilities than those provided by other systems. In March 2007, the acronym WGS was changed to Wideband Global SATCOM.

A major part of the U.S. military's global satellite communications, the Wideband Global SATCOM Satellite (WGS) system helps the U.S. Military through the operation of the control systems and provides long haul communications for the Department of Defense.

Satellite description 
WGS-5 is based on the BSS-702HP satellite bus. It has a mass of  and a design life of fourteen years. Its two solar panels generate upwards of 11 kW of power. The satellite is equipped with X-band and Ka-band transponders. A R-4D bi-propellant rocket motor and four XIPS-25 ion engines provide propulsion for maneuvering.

Launch 
WGS-5 was launched by the United Launch Alliance on a Delta IV M+ (5,4) launch vehicle, named Delta 362, from the Space Launch Complex (SLC-37B) at the Cape Canaveral Air Force Station (CCAFS) at 00:27 UTC on 25 May 2013. The satellite was placed into a supersynchronous transfer orbit. From there, the satellite was maneuvered into geostationary orbit. 

A launch attempt 24 hours before was aborted due to a problem with a helium pressurization line. The launch was successful.

Wrist brace. A  wrist brace  is a supportive garment worn around the wrist to reinforce and protect it against strains and sprains during strong use, or as a splint to help healing. Wrist braces are common accessories in injury rehabilitation processes involving the wrist. They immobilize the joint and provide heat and compression to the wrist bones and ligaments. Currently, they are made with a rigid tissue nylon fabrics or neoprene that allows limited mobility of the hand and wrist and  are usually fixed with Velcro, some times with extensions to ensure they cover part of the hand adhering around thumb. In severe cases, they incorporate metal "spines" to better immobilize the joint.

Uses

They are indicated for wrist trauma with and without fracture, immobilization of the joint, postoperative synovitis, recurrent degenerative sprains or articulation inflammations, among many other cases.

In rehabilitation to immobilize the wrist into a neutral position, which "theoretically  minimizes stress at the repair site".

Use in sports
The wrist braces have a protective role in activities where wrists require extraordinary effort like weight lifting or bodybuilding. In these cases, using pressure around the wrist may prevent sprains and strains.

Finally, are used in sports which force the wrist play, as those played with a paddle or racket (tennis, paddle, badminton) or hockey. Some times they have a double purpose: protect the wrist from injuries and wipe the sweat from the forehead. For this purpose they are made in absorbent materials such as cotton or plush.

In artistic gymnastics, gymnasts will sometimes wear wrist guards to absorb the impact on the skills they perform. The guards are commonly worn for Vaulting and Floor exercises. The design is modified between women and men.
