IBM PC Network. The IBM PC Network was IBM PC's first LAN system. It consisted of network cards, cables, and a small device driver known as NetBIOS (Network Basic Input/Output System). It used a data rate of 2 Mbit/s and carrier-sense multiple access with collision detection.

NetBIOS was developed by Sytek Inc as an API for software communication over this IBM PC Network LAN technology; with Sytek networking protocols being used for communication over the wire. IBM's later Token Ring network emulated the NetBIOS application programming interface, and it lived on in many later systems.

Broadband
The original broadband version in 1984 communicated over 75 Ω cable television compatible co-axial cable with each card connecting via a single F connector. Separate transmit and receive frequencies were used. Cards could be ordered that used different frequencies so multiple cards could transmit simultaneously, at 2 Mbit/s each. A Sytek head-end device was required to translate from each card's transmit frequency to the destination card's receive frequency. Frequency-division multiplexing allowed the cable to be shared with other voice, video, and data traffic.

Baseband
Later, in 1987 a much cheaper "baseband" version, also running at 2 Mbit/s connected computers in daisy-chain style using twisted-pair cables with 6P2C modular telephone connectors (often mistermed "RJ11"). Interface cards had two 6P2C sockets for connecting to left and right neighbor nodes. The unused sockets at the ends of the network segment had to be fitted with a terminator on one end of the chain and a wrap plug on the other. A hybrid star topology was possible using a hub.

Jerry S. Rawls. Jerry S. Rawls is an American businessman and philanthropist. He is the co-founder and chairman of Finisar.

Biography

Early life
Jerry Rawls was born in Houston, Texas, and graduated from Bellaire High School in Houston in 1962. He earned his Bachelor of Science Degree in Mechanical Engineering from Texas Tech University in 1967. While at Texas Tech, he played freshman basketball, was an officer of Phi Gamma Delta fraternity, and was a member of several other student organizations. He went on to earn a Master of Science Degree in Industrial Administration from the Krannert School of Management at Purdue University in 1968.

Career
He joined Raychem Corporation, a materials science and engineering company in Menlo Park, California and began a twenty-year career with them. He served in various capacities including National Sales Manager and Manager of Product Marketing. During his last six years there, he was General Manager of two divisions.

In 1988,he co-founded Finisar Corporation, a fiber optics company, with Frank H. Levinson. The goal for Finisar was to build cost effective gigabit optical transceivers to provide the optical input and output for high-speed computer networks. In 1992, Finisar proposed using multi-mode optics to dramatically lower the cost of gigabit optical links in data centers. Finisar’s proposal for gigabit multimode optics was adopted by the ANSI committee as the basis for today’s Fibre Channel Standard and later by the IEEE as the Gigabit Ethernet Standard.

In 1999 the company went public and raised $149.3 million. By the close of trading on the first day Finisar stock rose 373%, making Finisar the seventh largest first day gainer in the history of Wall Street at that time. The company now employs 9,000 people and has facilities and operations in California as well as in Dallas, Philadelphia, Boston, Champaign-Urbana, Malaysia, Singapore, Shanghai, Shenzhen, Sydney, Tel Aviv, Sweden, Denmark, India and Korea.

Forbes included Jerry in one of its lists of Corporate America’s 500 Most Powerful People.

University donations
The Rawls College of Business and The Rawls Course at Texas Tech University are named for him. On October 2, 2003, Rawls Hall at Purdue University was also named in honor of Rawls.

Object graph. In computer science, in an object-oriented program, groups of objects form a network through their relationships with each other, either through a direct reference to another object or through a chain of intermediate references. These groups of objects are referred to as object graphs, after the mathematical objects called graphs studied in graph theory.

An object graph is a view of an object system at a particular point in time. Unlike a normal data model such as a Unified Modeling Language (UML) class diagram, which details the relationships between classes, the object graph relates their instances. Object diagrams are subsets of the overall object graph.

Object-oriented applications contain complex webs of interrelated objects. Objects are linked to each other by one object either owning or containing another object or holding a reference to another object. This web of objects is called an object graph and it is the more abstract structure that can be used in discussing an application's state.

Physical representation
An object graph is a directed graph, which might be cyclic. When stored in RAM, objects occupy different segments of the memory with their attributes and function table, while relationships are represented by pointers or a different type of global handler in higher-level languages.

Examples
For instance, a Car class can compose a Wheel one. In the object graph a Car instance will have up to four links to its wheels, which can be named frontLeft, frontRight, back Left and back Right.
An example of an adjacency list representation might be something as follows: 

  c:Car → {front Left:Wheel, front Right:Wheel, back Left:Wheel, back Right:Wheel}.

Thomas Chang. Thomas Ming Swi Chang,  (born 8 April 1933) is a Chinese-born Canadian inventor, physician, and physiologist. 

While an undergraduate at McGill University in 1957, Chang invented the world's first artificial cell. Working with improvised materials like perfume atomizers inside his dorm room turned laboratory, Chang managed to create a permeable plastic sack that would effectively carry haemoglobin almost as effectively as a natural blood cell. He went on to complete his B.Sc. (1957), M.D., C.M. (1961), and Ph.D (1965) degrees at McGill. Chang's career continued as founder and Director of the Artificial Cells and Organs Research Centre and Professor of Physiology, Medicine & Biomedical Engineering in the Faculty of Medicine at McGill University.

In the late 1960s he discovered enzymes carried by artificial cells could correct some metabolic disorders and also developed charcoal-filled cells to treat drug poisoning. His work on finding a safe blood substitute brought him to prominence in the 1980s and 1990s, earning him an Order of Canada. The Canadian Academy of Health Sciences states, "Dr. Chang’s original ideas were years ahead of the modern era of nanotechnology, regenerative medicine, gene therapy, stem cell/cell therapy and blood substitutes. He was nominated twice for the Nobel Prize".

In 2011, Dr. Chang was voted the winner of the Greatest McGillian contest organized by the McGill Alumni Association for McGill's 190th anniversary.

Honda CR250M. The Honda CR250M is a two-stroke single-cylinder motorcycle manufactured by Honda from March 1973 until 1976, when it was replaced by the Honda CR250R.

Background
Honda had developed its global motorcycle brand through track racing, with Soichiro Honda collecting the world's best engineers together to create winning road motorcycles such as the Honda RC116. However, Honda pulled out of motorcycle racing in 1967, leaving it with a world class development team with nothing to do. Up until this point, motocross had been dominated by four-stroke-powered machines, and had no official national championship in Japan. Further, Soichiro Honda had publicly announced that Honda would never build two-stroke-powered motorcycles.

The Japan Motorcycle Association introduced a domestic motocross championship from 1967, to which the group of Honda engineers - like their development counterparts at Suzuki and Yamaha - developed lighter weight two-stroke-powered machine. Suzuki's development programme had started in 1965, which by 1970 had produced the Suzuki RH70, which ridden by Belgium's Joel Robert won Japan its first FIM Motocross World Championship.

In August 1971, the Honda development team took a two-stroke prototype to a National Championship motocross race to Mine, Yamaguchi, where it was recognised as a Honda. As a result, Soichiro Honda gave his reluctant backing to producing not only a works competitive motocross racer, but also an out of the box version as well.

Development
The Honda CR250M had a two-stroke 29 horsepower engine, and weighed in at . Designed by Soichiro Miyakoshi, the prototype production machine began testing in Japan in 1971, and on California motocross tracks in 1972. The CR250M was Honda's first two-stroke production race bike, the first competition dirt bike that Honda built from scratch instead of adapting a street bike, and the first production motocrosser.  A chrome-moly frame, aluminum bodywork and plastic fenders contributed to its light weight, even after restyling when initial tests showed the frame to be too fragile, potentially bending after less than an hour of riding.

Production
Named the CR250M globally, it was subtitled the Elsinore in North America, after the offroad race in Lake Elsinore, California, the best-known off-road race of the late 1960s and early 1970s. The popularity of the CR250M and its derivatives soared after Gary Jones rode a stock machine to win the 1973 AMA 250 national motocross series.

In 1974 the CR250M was followed by its smaller version, the Honda CR125M, and the first US Honda factory that opened in 1979 in Marysville, Ohio built CR250Ms.

Model codes
The 357 was released as a Honda CR250M in the years 1973 and 1974, and the 381 was released as a CR250M1 in 1975 and as a CR250M'76 in 1976.

SteadyShot. SteadyShot is the trademarked name of the integrated image stabilisation technologies used in Sony video camcorders, DSLR cameras, mirrorless cameras and on Sony Xperia smartphones and tablets. Different versions of these technologies are known as Super SteadyShot (SSS) in Sony's Cyber-shot product line, in addition to SteadyShot INSIDE (SSI) and Optical SteadyShot (OSS) in the Sony α family.

Design
When a camera is operated hand-held, the operator's shaky hands can cause instabilities in the captured image stream. SteadyShot technology works inside the body of the camera. It uses motion sensors to detect the user's movements. SteadyShot then compensates for some of these movements, in some versions by moving the optics (OSS) and in some versions by moving the image sensor (also called IBIS: In Body Image Stabilisation) in an opposite direction to the movement. 

This approach is contrasted to digital image stabilization in which the physical image is allowed to "track" the scene on the CCD by software to produce a stable image. The digital technique requires the pixel count to be increased to allow the image to move on the sensor while keeping reference points within the boundaries of the capture chip.

Balanced Optical SteadyShot
Instead of moving only the sensor or only one of the lenses, Balanced Optical SteadyShot (BOSS) moves the whole lens block to compensate for camera shake. Sony claims this is 13 times more effective than previous versions of SteadyShot. This feature is unique to Sony camcorders and action cams. It was introduced in the beginning of 2012.

SteadyShot is entirely internal to the camcorder unlike external stabilisation systems such as the Steadicam.

Strained silicon. Strained silicon is a layer of silicon in which the silicon atoms are stretched beyond their normal interatomic distance. This can be accomplished by putting the layer of silicon over a substrate of silicon–germanium (). As the atoms in the silicon layer align with the atoms of the underlying silicon germanium layer (which are arranged a little further apart, with respect to those of a bulk silicon crystal), the links between the silicon atoms become stretched, thereby leading to strained silicon. Moving these silicon atoms further apart reduces the atomic forces that interfere with the movement of electrons through the transistors and thus improved mobility, resulting in better chip performance and lower energy consumption. These electrons can move 70% faster allowing strained silicon transistors to switch 35% faster.

More recent advances include deposition of strained silicon using metalorganic vapor-phase epitaxy (MOVPE) with metalorganics as starting sources, e.g. silicon sources (silane and dichlorosilane) and germanium sources (germane, germanium tetrachloride, and isobutylgermane).

More recent methods of inducing strain include doping the source and drain with lattice mismatched atoms such as germanium and carbon. Germanium doping of up to 20% in the P-channel MOSFET source and drain causes uniaxial compressive strain in the channel, increasing hole mobility. Carbon doping as low as 0.25% in the N-channel MOSFET source and drain causes uniaxial tensile strain in the channel, increasing electron mobility. Covering the NMOS transistor with a highly stressed silicon nitride layer is another way to create uniaxial tensile strain. As opposed to wafer-level methods of inducing strain on the channel layer prior to MOSFET fabrication, the aforementioned methods use strain induced during the MOSFET fabrication itself to alter the carrier mobility in the transistor channel.

History
The idea of using germanium to strain silicon for the purpose of improving field-effect transistors appears to go back at least as far as 1991.

In 2000, an MIT report investigated theoretical and experimental hole mobility in SiGe heterostructure-based PMOS devices.

In 2003, IBM was reported to be among primary proponents of the technology. 

In 2002, Intel had featured strained silicon technology in its 90nm X86 Pentium microprocessors series in early 2000. In 2005, Intel was sued by AmberWave company for alleged patent infringement related to strained silicon technology.

Isaac Babbitt. Isaac Babbitt (July 26, 1799 – May 26, 1862) was an American inventor. In 1839, he invented a bearing made of a low-friction tin-based metal alloy, Babbitt metal, that is used extensively in engine bearings today.

Biography 
Babbitt was born on July 26, 1799, in Taunton, Massachusetts. He was a goldsmith by trade, who experimented with metal alloys. In 1824, he made the first Britannia metal manufactured in the United States, from which he sold table wares as Babbitt, Crossman & Company. As this proved financially unsuccessful, he withdrew, and in 1834 moved to Boston. There he engaged as superintendent for the South Boston Iron Company, better known as Alger's foundries, where he produced the first brass cannon in the United States. Also while there, in 1839, he invented the widely used metal now known as Babbitt metal, an alloy of four parts copper, eight of antimony, and twenty-four of Banca tin, used for reducing the friction of axles in heavy machinery. For this invention he received in 1841 a gold medal from the Massachusetts Charitable Mechanic Association, and afterward the United States Congress granted him $20,000. He subsequently patented this material in England (1844) and in Russia (1847). For some time, he devoted his attention to the production of the metal, and he was also engaged in the manufacture of soap.

He died in Somerville, Massachusetts, May 26, 1862, aged 62.

Undertank heater. Under Tank Heater (UTH), also called heating mat or heating pad, is a heating device created by the pet industry for husbandry of reptiles and amphibians.  It is a  flat piece of metal and plastic that provides a convenient and easy way to heat your reptiles, amphibian and even aquariums fish tanks. They provide constant heat, allowing you to create the optimal temperature gradient within the nursery

Use
The heater is usually placed at one end of the base, covering 1/3 of the base of the terrarium but alternately it may also be placed on a wall. The temperature emitted will pass through the terrarium walls and substrate, creating a temperature gradient throughout the enclosure. The hot zone is just above the heater; the opposite zone, the cold zone, is where the live food and the water bowl would be placed. A substrate between the pad and the tank is necessary, as is a thermostat or rheostat to prevent it from overheating and burning the animals. Malfunction in an under tank heater could result in higher temperatures which might harm animals or even start a fire.

Aquarium can also be heated by the use of heating mats which are placed beneath the aquarium. Glass is, however, a poor conductor of heat and thus reduces the efficiency of this method of heating.
