Pioneers in Engineering. Pioneers in Engineering (PiE) is a student-run organization that promotes the study of science, technology, engineering, and mathematics, collectively known as STEM fields. The organization was established in 2008 as a non-profit corporation by University of California, Berkeley student, Xiao-Yu Fu. The University provides training and mentorship opportunities for local high school students to improve their technological skills, by participating in a robotics competition, during which each student team designs, builds, and programs functional robots. Since 2008, over 20 schools have participated in the program.

Background
Pioneers in Engineering was founded in 2008 by University of California, Berkeley student and Tau Beta Pi member, Xiao-Yu Fu. The organization's office is in UC Berkeley's O'Brien Hall. Staff members, including University of California undergraduates and graduates, design and assemble robotics starter kits for the competition, develop mentors for the program, plan and manufacture the annual competition field, and oversee public relations and internal communications. , the organization has expanded to include 107 staff members.

In preparation for the annual competition, robotic kits are distributed to groups of high schools students, who are paired with undergraduate mentors who assist the teams during the competition. A final tournament is held at the end of the season, allowing the student teams to reveal their work, for which awards are presented.

John Patterson (meteorologist). John Patterson OBE, (January 3, 1872 – February 22, 1956) was a Canadian physicist and meteorologist.

Born on a farm in Oxford County, Ontario, he was one of thirteen children of Francis Patterson and Annie (Telfer). He matriculated to the University of Toronto, graduating in 1900 with a B.A. in engineering, and was awarded a 1851 Exhibition Science Research Scholarship to study physics for his M.A. at the Cavendish Laboratory, University of Cambridge. There he performed studies of thin metallic films and their electrical properties, ionization of the air, and the variation of electrical resistance of metals when exposed to magnetic fields.

Patterson traveled to India in 1903 where he served as professor of physics at the University of Allahabad, until in January 1905 he was named imperial meteorologist to the Government of India at Simla. On January 1, 1906, he was married to Margaret Norris, a medical practitioner and professor of obstetrics working in India. The couple had two children, one of whom died in India. With John suffering from ill health, the couple left for Toronto with their son Arthur in 1910.

He became a physicist for the Canadian Meteorological Service, where he was responsible for organizing a pilot program for performing upper air observations using balloons. In 1912 he was placed in charge of the newly formed department of physics at the Central Office in Toronto. During the First World War, he worked for the British Admiralty to perform an experiment in extracting helium from natural gas. Following the war, he was involved in designing a new barometer and was responsible for developing the 3-cup anemometer now in widespread use. In 1925 he became assistant director of the Meteorological service, then in 1929 he was named director (controller), succeeding the retiring Sir Frederic Stupart. Patterson held this post until his retirement in 1946. He was elected to serve as president of the American Meteorological Society during 1930–31 and president of the Royal Canadian Institute in 1932–33.

In 1954, the Patterson Distinguished Service Medal was created in his honnor and attributed to him.

Aluminium powder. Aluminium powder is powdered aluminium.

This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s. The resulting powder might then be processed further in a ball mill to flatten it into flakes for use as a coating or pigment. Aluminium powder features low density with high conductivity.

Characteristics

Powdered aluminium shares many of the physical characteristics of bulk aluminium such as its molecular weight of 26.981538 g mol−1, melting point of 660 °C, and a boiling point of 2460 °C.

Usage 
 autoclave aerated concrete
 cosmetic colourant
 fingerprint powder
 metallic paint
 pyrotechnics (including the M-80 firecracker)
 refractory
 rocket and missile fuel such as the solid rocket boosters of the Space Shuttle
 thermite
 Electrically conductive filler material for EMI shielding applications.

Depending on the usage, the powder is either coated or uncoated.

Safety
Aluminium is insoluble.  Although aluminium is unlikely to be adsorbed into the blood stream, its inhalation can cause severe irritation and hinder the ventilation mechanism.  High levels of exposure over many years may result in aluminosis which causes pulmonary fibrosis.

Aluminium powder and dust is highly flammable and creates a significant risk of fire or explosion.  There have been many incidents in industries which produce such dusts and powders.

Metal powder. Metal powder is a metal that has been broken down into a powder form. Metals that can be found in powder form include aluminium powder, nickel powder, iron powder and many more. There are four different ways metals can be broken down into this powder form:
 Direct reduction
 Gas atomization
 Liquid atomization
 Centrifugal atomization

Processes 
The following processes can be used to produce metal powder:
 Direct reduction is the result of blending carbon with iron oxide ore, heating the mixture, removing the sponge iron from the carbon, grinding it, annealing it, and regrinding to make the powder form usable for manufacturing.
 Gas atomization occurs when a molten metal is passed through a passageway to a gas-filled chamber that cools the metal.  As it falls, it is collected and annealed into a powder.
 Liquid atomization is similar to gas atomization, but instead the metal is sprayed with high-pressure liquid which solidifies the droplets more rapidly. This results in the powder being more porous, smaller, and cleaner.
 Centrifugal atomization occurs when a metal is put into a chamber as a rod and electrically melted, at the end of the rod, to produce melted droplets that fall into another chamber and then solidify.

Types and Uses 

Back in the early 1900's, metal powder was the currency used in the United States of America. Depending on the market, metal powder can be more valuable than gold. The following are the types and uses of metal powder:
 Aluminum powder: Fireworks, metallic paints, manufacturing in solar cells in the green energy sector
 Bismuth powder: Production of batteries, welding rods, creating alloys
 Cadmium powder: Glazed used on ceramics, transparent conductors, nickel-cadmium batteries
 Iron powder: Magnetic products, printing, brake pads, certain types of dyes and stains
 Nickel powder: used for corrosion resistance, such as in the marine industry
 Raney nickel: used as a catalyst
 Platinum black: used as a catalyst
 Titanium powder: used in aerospace applications,  medical implants and sporting goods.

IPT-16 Surubim. The IPT-16 Surubim was a Brazilian single-seat, single engined experimental light aircraft. A single example was built and flown in 1959.

Design and development

In 1949, Joseph Kovács, a Hungarian-born aircraft engineer working at the Instituto de Pesquisas Tecnologicas (IPT - Institute of Technical Research) of the University of São Paulo proposed to design and build an experimental high performance light aircraft powered by a surplus Hirth HM 506 engine that had been imported into Brazil before the Second World War for use in an unbuilt aircraft design. The IPT, however, was busy on other projects, and so did not back Kovács' proposed design. Kovács, with fellow IPT engineer Sylvio de Oliveira, started construction of the design, named "Surubim" (little devil), in a rented workshop.

The Surubim was a low-winged monoplane with a retractable tailwheel undercarriage of all wooden construction with plywood skinning, using Brazilian Pine and Freijo, two indigenous woods. The wings were fitted with trailing edge flaps and fixed leading edge slots. The pilot sat in an enclosed cockpit.
  
When Kovács left IPT in 1951, de Oliveira continued work on the prototype, which was acquired by the IPT in 1953 for use as a flying test bed, gaining the designation IPT-16. Construction of the prototype continued at a slow pace, with the prototype being shown at an exhibition in São Paulo in 1956, but remained unflown for several more years.

Operational history
The IPT-16 finally made its maiden flight on 17 September 1959. Despite being underpowered and using a fixed pitch wooden propeller, performance was good, reaching a level speed of  and  in a dive. It was used by the IPT for three years, after which it was transferred to the Rio Claro City Aero Club for use as an aerobatic aircraft, where it remained in use until at least 1977.

It was presented to the Museu Aeroespacial at Rio de Janeiro in 1988, where, after restoration, it was put on display.

American Electric Piranha. The American Electric Piranha (also named Blair-American USA or American USA) was a prototype American counter-insurgency aircraft. Designed by Milt Blair and Dick Ennis in the early 1960s, it was built by the American Electric Corporation.

Developed for use by the  United States Air Force under Project Little Brother, initial flight testing of the Piranha took place at Mojave Airport in California; following delivery for evaluation, it was tested at Eglin Air Force Base in Florida. The design armament of the Piranha was two pods each carrying four Zuni unguided rockets, mounted on the aircraft's wingtips, and a single  bomb on a belly hardpoint.

Evaluation of the Piranha ceased following the death of Milt Blair in an unrelated aircraft accident. The prototype, N1518, is flown by a private owner in Kansas.

Leonardo S. Sarao. Leonardo Salvador Sarao (13 April 1921 – 31 July 2001) was the founder and owner of the Sarao Motors, a company known for designing, manufacturing and selling the jeepney, the most popular mode of transportation in the Philippines.  He is not the first person to alter the surplus jeeps left behind by the United States Army from World War II, but he saw them as a business opportunity for mass transportation. He redesigned the surplus jeeps to increase its functionality by extending the body to accommodate at least twice the number of passengers and by putting some railings at the back and top for extra passengers to cling to, and for cargoes.  He revolutionized a burgeoning industry and changed the life of generations of Filipinos.

Leonardo Sarao was awarded The Outstanding Filipino Award (TOFIL) in 1991 for Entrepreneurship.  He started Sarao Motors from a borrowed PHP700.  Though he only attained Grade 6 level of education because of poverty, he was able to make the company grow into a multimillion peso conglomerate.

Czerwinski-Shenstone UTG-1 Loudon. The UTG-1 Loudon was an intermediate glider designed and built at the University of Toronto in Canada during the late 1940s.

Design and development
By 1947 Canadian glider pilots urgently needed a new intermediate performance glider for club use and cross-country flying. Concurrently the Loudon Professor of Civil Engineering at the University of Toronto proposed that his 4th year students gain experience by building a glider. Waclaw Czerwinski and Beverley S. Shenstone designed a small glider for the students to build, which was completed within two years and flown for the first time on 5 November 1949.

Construction of the Loudon was primarily of wood with fabric and plywood skinning, following contemporary standard practice of a shoulder set two piece wing immediately aft of the enclosed cockpit. The fuselage was built up from spruce frames and stringers with plywood covering incorporating the integral fin. The wing consisted of a single cantilever spar with a ply sandwich leading edge torque tube. Made up ribs forming the wing section aft of the spar and all control surface, were fabric covered.

Controls were entirely conventional with ailerons near the wing-tips, tailplane with elevators at the base of the fin and a rudder hinged from the rear of the fin.

Support on the ground consisted of a large nose skid under the nose extending from the nose back to a semi-recessed mainwheel, aft of the centre of gravity a steel sprung tailskid at the base of the fin and re-inforced wingtips.

Flight testing of the Loudon was successful and an experimental type certificate was issued by the Canadian Department of Transport in November 1952, receiving the registration CF-ZBN-X.

Operational history
The Loudon was used for several years before an accident wrote the aircraft off.

Design-Oriented Programming. Design-oriented programming is a way to author computer applications using a combination of text, graphics, and style elements in a unified code-space. The goal is to improve the experience of program writing for software developers, boost accessibility, and reduce eye-strain. Good design helps computer programmers to quickly locate sections of code using visual cues typically found in documents and web page authoring.

User interface design and graphical user interface builder research are the conceptual precursors to design-oriented programming languages. The former focus on the software experience for end users of the software application and separate editing of the user interface from the code-space. The important distinction is that design-oriented programming involves user experience of programmers themselves and fully merges all elements into a single unified code-space.

Geoffrey Drake-Brockman (engineer). Brigadier Geoffrey Drake-Brockman MC (1885–1977) was a Western Australian civil engineer, and an Australian Army officer in both World Wars.

In 1908 he was involved in mapping the route for the railway-line from Kalgoorlie, Western Australia to Port Augusta, South Australia. In 1921 he was appointed commissioner of the Department of the North-West (of Western Australia) based in Broome; as commissioner he recommended a survey of agricultural land at the Ord River, the planting of cotton and the development of the Kimberley region. In 1946 he was appointed assistant-director of public works, and in 1949 chairman of the Western Australian Transport Board, retiring in 1952.

As a soldier, in World War I he was awarded the Military Cross, and commanded the 9th Field Company in 1917–18. In World War II he was posted to Army Headquarters, Melbourne; as colonel, then brigadier, he occupied senior engineering staff posts.

In retirement, he wrote an autobiography, The Turning Wheel (1960).

Family

His parents were Frederick Slade Drake-Brockman and Grace Bussell. He had four sisters and two brothers, including Major General Edmund Drake-Brockman (1884-1949) and Lady Deborah Vernon Hackett (1887-1965).

In 1917 he married Alice Annie Wardlaw Milne in Hertfordshire, England. She died in 1918.

In 1921 he married Henrietta Frances York Jull (1901-1968) in Guildford, Western Australia. She became a prolific author and also wrote several plays. They had two children, a girl and a boy. A grandson, Geoffrey was named after him.

GP5 chip. The GP5 is a co-processor accelerator built to accelerate discrete belief propagation on factor graphs and other large-scale tensor product operations for machine learning.  It is related to, and anticipated by a number of years, the Google Tensor Processing Unit

It is designed to run as a co-processor with another controller (such as a CPU (x86) or an ARM/MIPS/Tensilica core).  It was developed as the culmination of DARPA's Analog Logic program 

The GP5 has a fairly exotic architecture, resembling neither a GPU nor a DSP, and leverages massive fine-grained and coarse-grained parallelism.  It is deeply pipelined. The different algorithmic tasks involved in performing belief propagation updates are performed by independent, heterogeneous compute units. The performance of the chip is governed by the structure of the machine learning workload being evaluated.  In typical cases, the GP5 is roughly 100 times faster and 100 times more energy efficient than a single core of a modern core i7 performing a comparable task.  It is roughly 10 times faster and 1000 times more energy efficient than a state-of-the art GPU.  It is roughly 1000 times faster and 10 times more energy efficient than a state-of-the-art ARM processor.  It was benchmarked on typical machine learning and inference workloads that included protein side-chain folding, turbo error correction decoding, stereo vision, signal noise reduction, and others.

Analog Devices, Inc. acquired the intellectual property for the GP5 when it acquired Lyric Semiconductor, Inc. in 2011.
