RG-6. RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications.  An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, RG-6, is generic and is applied to a wide variety of cable designs, which differ from one another in shielding characteristics, center conductor composition, dielectric type and jacket type.  RG was originally a unit indicator  for bulk radio frequency (RF) cable in the U.S. military's Joint Electronics Type Designation System. The suffix /U means for general utility use. The number was assigned sequentially. The RG unit indicator is no longer part of the JETDS system (MIL-STD-196E) and cable sold today under the RG-6 label is unlikely to meet military specifications. In practice, the term RG-6 is generally used to refer to coaxial cables with an 18AWG (1.024mm) center conductor and 75ohm characteristic impedance.

Applications 
A common type of 75 ohm coaxial cable is cable television (CATV) distribution coax, used to route cable television signals to and within homes.  CATV distribution coax typically has a copper-clad steel (CCS) center conductor and a combination aluminum foil/aluminum braid shield, typically with low coverage (about 60%). 75 ohm  cables are also used in professional video applications, carrying either base band analog video signals or serial digital interface (SDI) signals; in these applications, the center conductor is ordinarily solid copper, the shielding is much heavier (typically aluminum foil, and 95% copper braid), and tolerances are more tightly controlled, to improve impedance stability.

Cables typically have connectors at each end.

Types 
Like most cables, RG-6-style cables are available in several different types designed for various applications, including:

Plain or house wire is designed for indoor or external house wiring.

"Flooded" cable is infused with water blocking gel for use in underground conduit or direct burial.

Messenger or aerial may contain some waterproofing but is distinguished by the addition of a steel messenger wire along its length to carry the tension involved in an aerial drop from a utility pole.

Plenum wire comes with a Low Smoke Zero Halogen (LSZH) jacket that burns but does not produce toxic smoke. LSZH is typically irradiated PVC. Heating drives off volatiles that leaves the resulting product more heat resistant.

Attenuation/signal loss 
Cables attenuate a signal in direct proportion to length.  Attenuation increases with frequency due to skin effect.

Mark Pauline. Mark Pauline (born December 14, 1953) is an American performance artist, new media artist, and machine inventor. He is known as founder and director of Survival Research Laboratories.

Early life and education 
After high school he had a job at Eglin Air Force Base in Florida, as a sub-contractor maintaining target robots. He is a 1977 graduate of Eckerd College in St. Petersburg, Florida.

Career 
Pauline founded SRL in 1978 and it is considered the premier practitioner of "industrial performing arts", and the forerunner of large scale machine performance.  Although acknowledged as a major influence on popular competitions pitting remote-controlled robots and machines against each other, such as BattleBots and Robot Wars, Pauline shies away from rules-bound competition preferring a more anarchic approach.  Machines are liberated and re-configured away from the functions they were originally meant to perform.  

Pauline has written of SRL, "Since its inception SRL has operated as an organization of creative technicians dedicated to re-directing the techniques, tools, and tenets of industry, science, and the military away from their typical manifestations in practicality, product or warfare." Since its beginning through the end of 2006, SRL has conducted about 48 shows, with long titles such as "A Cruel and Relentless Plot to Pervert the Flesh of Beasts to Unholy Uses".  

In the summer of 1982, Pauline severely damaged his right hand while experimenting with solid rocket fuel.  In August 1990, ArtPark, a state-sponsored arts festival in Lewiston, New York, cancelled a Pauline performance when it turned out he intended "to cover a sputtering Rube Goldberg spaceship with numerous Bibles" that would "serve as thermal protective shields" and be burned to ashes in the course of the performance.

According to Pauline "I like to make machines that can just do their own shows... machines that can do all that machines in the science fiction novels can do. I want to be there to make those dreams real."

Wave-piercing hull. A wave-piercing boat hull has a very fine bow, with reduced buoyancy in the forward portions. When a wave is encountered, the lack of buoyancy means the hull pierces through the water rather than riding over the top, resulting in a smoother ride than traditional designs, and in diminished mechanical stress on the vessel.  It also reduces a boat's wave-making resistance.

Design theory calls for very long thin hulls, so in practice most are multi-hulls such as catamarans and trimarans. 

The main current usage areas are passenger ferries and naval ships.

Technological Institute of Textile & Sciences. The Technological Institute of Textile and Sciences (TITS) is an Indian technical college. It offers engineering and postgraduate programs. 

The institute provides lectures by in-house and visiting faculty, discussions, seminars, project assignments and visits to industrial and project sites. The institute is attached to a textile factory where students train under actual mill conditions and working environments. Students undergo extensive practical and theoretical training. They learn to handle mechanical and administrative issues independently. TITS graduates are readily accepted by the textile industry.

Administration 
Its administration vests in the TIT&S College Managing Committee. The committee is constituted according to the constitution prescribed by the All India Council for Technical Education.

The institute is attached to a textile mill to train students under actual working conditions and for conducting research. The college's focus on textile technology is unique in India and uncommon elsewhere. It is among the few (others being the National Institutes of Technology and Indian Institutes of Technology) in India that offers degrees in technology (BTech with Honours) at the undergraduate level as opposed to a B.E. (Bachelor of Engineering).

The Institute is NAAC accredited with B++ Grade and is approved under Section 2(f) and 12 (B) of UGC Act 1956.

History 
The college was founded in 1943 by Padma Vibhushan, Dr. Ghanshyam Das Birla and Pushkar D Makharia under the auspices of the Birla Education Trust.

The college was initially affiliated with the Department of Industrial Training, Punjab, for a 3-year diploma course in spinning and weaving technology. TIT&S remained part of the Birla Education Trust until 31 March 1985. Thereafter, it separated from the trust as an independent society. It was registered under the West Bengal Societies Registration Act of 1961 known as "The Technological Institute of Textiles," which was formed to manage it. To reflect the expanded instructional facilities and new courses, it was renamed "The Technological Institute of Textile & Sciences".

Neocognitron. 

The neocognitron is a hierarchical, multilayered artificial neural network proposed by Kunihiko Fukushima in 1979. It has been used for Japanese handwritten character recognition and other pattern recognition tasks, and served as the inspiration for convolutional neural networks.

Previously in 1969, he published a similar architecture, but with hand-designed kernels inspired by convolutions in mammalian vision. In 1975 he improved it to the Cognitron, and in 1979 he improved it to the neocognitron, which learns all convolutional kernels by unsupervised learning (in his terminology, "self-organized by 'learning without a teacher'").

The neocognitron was inspired by the model proposed by Hubel & Wiesel in 1959. They found two types of cells in the visual primary cortex called simple cell and complex cell, and also proposed a cascading model of these two types of cells for use in pattern recognition tasks.

The neocognitron is a natural extension of these cascading models. The neocognitron consists of multiple types of cells, the most important of which are called S-cells and C-cells. The local features are extracted by S-cells, and these features' deformation, such as local shifts, are tolerated by C-cells. Local features in the input are integrated gradually and classified in the higher layers. The idea of local feature integration is found in several other models, such as the Convolutional Neural Network model, the SIFT method, and the HoG method.

There are various kinds of neocognitron. For example, some types of neocognitron can detect multiple patterns in the same input by using backward signals to achieve selective attention.

Passaic-class monitor. The Passaic-class ironclad monitors of the U.S. Navy saw service in the U.S. Civil War and the Spanish–American War. The class was an improved version of  equipped with a 15-inch Dahlgren gun in place of one of the 11-inch guns.

Design

Naval architect and engineer John Ericsson designed the Passaic-class warships, drawing upon lessons learned from the first , which he also designed. The Passaic monitors were larger than the original Monitor and had their pilothouses atop the turret, rather than near the bow. This allowed a wider field of view and easier communications between captain, pilot and crew. The shape of the hull was an improvement; a fuller and rounder lower hull, far more boat-like than that of the Monitor, and with a less pronounced overhang. The Passaic class featured an  funnel and improved ventilation. In combination, the significant hydrodynamic refinements and improved draught to the boilers resulted in a one-knot speed increase over the prototype monitor, despite the Passaic having a lower specific power than Monitor (Passaic being almost 400 tons heavier and yet with the same 320ihp-rated machinery). 

Having observed the new 15-inch Rodman cannon in fortifications and disappointed with the performance of the 11-inch Dahlgren versus , Assistant Secretary of the Navy Gustavus Fox required the new monitors to be equipped with at least one gun of 15-inch caliber, resulting in rush production of a new 15-inch Dahlgren. The turret was  in diameter inside with the  gun mounted flush because the muzzle diameter was too large for the turret opening. The large volume of propellant gases released inside the turret required the addition of a "smoke box" at the muzzle in the interior of the turret. As a result, the 15 in gunners could not see their targets and had to aim with the  or  guns. Lehigh had her 11-inch smoothbore replaced with an 8-inch Parrott rifle. Passaic also had this modification by July 1863, and, eventually, all surviving members of this class had an additional 15-inch smoothbore added.
Later improvements included an additional 50 tons of deck plating over the magazines and machinery spaces as well as rings fitted around the turret and pilot houses to prevent their pivoting machinery from being jammed by shot.

Ships in class
Warships of Passaic class included:

 Passaic
 Montauk
 Nahant
 Patapsco
 Weehawken
 Sangamon
 Catskill
 Nantucket

 Camanche

The first ship of the class was named for the city of Passaic, New Jersey.

Maintenance Trophy. The Maintenance Trophy is awarded by Lockheed Martin and was introduced in 1996 at the Fincastle competition.

Origins
The Lockheed Martin Fincastle Maintenance Trophy was first introduced during Fincastle 1996, which was held in New Zealand. It was felt the competition would strengthen relations between the competing countries, allowing them to learn from each other as well as involving the maintenance teams in the competitive spirit of Fincastle . It is designed to foster relations among the four competing nations (RAF, RCAF, RNZAF and RAAF) and encourage learning and sharing skills in a competitive atmosphere.

The competition runs in parallel to and is intrinsically linked to the Fincastle Competition, which the aircrew compete for. The competition is judged by a team of Senior Non-Commissioned Officers SNCOs, one from each nation, led by an Engineering Officer from the host country. Teams are examined on their flight line operations, the quality of their support elements, engineering skills and a team interview.

Midland Air Museum. The Midland Air Museum (MAM) is situated just outside the village of Baginton in Warwickshire, England, and is adjacent to Coventry Airport. The museum includes the Sir Frank Whittle Jet Heritage Centre (named after the local aviation pioneer and inventor of the jet engine), where many exhibits are on display in a large hangar. It also has a small hangar, and a fenced-off green area where many aircraft are on display in the open.

Aircraft on display

The museum's two largest aircraft are an Avro Vulcan B.2 and an Armstrong Whitworth Argosy AW.650 (series 101).  The restored Avro Vulcan is a delta-winged aircraft that was originally part of the V bomber force and could be equipped with nuclear missiles as part of Britain's role in NATO's nuclear deterrent force during the Cold War. It is on display near the museum's car park, together with an Avro Blue Steel missile, an early design format of such a nuclear missile, and a Boulton Paul BP.111A, an experimental delta-winged aircraft of the 1950s.

The museum also has an English Electric Canberra PR.3, two English Electric Lightnings (the RAF's fastest ever interceptor), two Gloster Meteors (one on loan from the Royal Air Force Museum), an Armstrong Whitworth Sea Hawk FGA.6, a Mil Mi-24 helicopter, and many others.

Common Building Block. Common Building Block (CBB) was a set of technical standards for laptop components introduced by Intel in 2005, and adopted by some manufacturers, including Asus, Compal, and Quanta.

Creation
In 2004, the Common Building Block program promoted the use of industry-accepted mechanical and electrical specifications for three notebook components: 14.1-inch, 15-inch, and 15.4-inch liquid crystal displays (LCDs); 9.5mm and 12.7mm optical disc drives (ODDs); and 2.5-inch hard disk drives (HDDs). The program consisted of:
A Web site to provide a centralized repository of information about the program, participants, and platform and ingredient specifications
A continually updated list of CBB-compliant ingredients (submitted by suppliers)
A testing and verification service for candidate products

The defunct repository site mobileformfactors.org was established to standardize components, and included:
Hard disk drives
Optical disc drives
Liquid crystal display panels
Battery packs
AC/DC power adapters
Keyboards
Customizable notebook panels

LAMMPS. Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is a molecular dynamics program from Sandia National Laboratories. LAMMPS makes use of Message Passing Interface (MPI) for parallel communication and is free and open-source software, distributed under the terms of the GNU General Public License.

LAMMPS was originally developed under a Cooperative Research and Development Agreement between two laboratories from United States Department of Energy and three other laboratories from private sector firms. , it is maintained and distributed by researchers at the Sandia National Laboratories and Temple University.

Features 

For computing efficiency, LAMMPS uses neighbor lists (Verlet lists) to keep track of nearby particles. The lists are optimized for systems with particles that repel at short distances, so that the local density of particles never grows too large.

On parallel computers, LAMMPS uses spatial-decomposition techniques to partition the simulation domain into small 3D sub-domains, one of which is assigned to each processor. Processors communicate and store ghost atom information for atoms that border their subdomain. LAMMPS is most efficient (in a parallel computing sense) for systems whose particles fill a 3D rectangular box with approximately uniform density. Lots of accelerators are supported by LAMMPS, including GPU (CUDA, OpenCL, HIP, SYCL), Intel Xeon Phi, and OpenMP, due to its integration with Trilinos.

LAMMPS also allows for coupled spin and molecular dynamics in an accelerated fashion.

LAMMPS is coupled to many analysis tools and engines as well. LAMMPS also can be coupled with free energy calculators, such as PLUMED and Colvar.
