Stephen Selkowitz. Stephen E. Selkowitz is an American building scientist, and a leading researcher of energy efficiency in building envelopes.  He is currently a senior advisor for building science at the Lawrence Berkeley National Laboratory. In 2014, he received the Award of Excellence from Engineering News-Record (formerly the Man of the Year award).

Life and career
Selkowitz was born March 8, 1948, and grew up in Newton, Massachusetts. His father was a pharmacist.

Selkowitz graduated from Harvard University with a B.A. in physics. While an undergraduate, Selkowitz's interest in the environment was increased through participation in Buckminster Fuller's World Game. He received a Master of Fine Arts in Environmental Design from the California Institute of the Arts (CalArts) in 1972. Before beginning his career at Lawrence Berkeley National Laboratory (Berkeley Lab), Selkowitz taught at CalArts and worked at a consulting engineering firm.

Selkowitz led research at Berkeley Lab to reduce the amount of heat transfer through windows. The low-emissivity (low-E) windows they developed have saved $7.7 billion on energy costs and 1.2 quadrillion BTUs, according to National Academy of Sciences' data. Selkowitz had to convince window manufacturers of the benefits of low-E glass before its use became widespread.

Awards
Selkowitz received the ENR Award of Excellence "for relentlessly working to reduce the carbon footprint of buildings and for moving the nation toward better building performance, as well as for being the master of commercializing energy-efficient building technologies and the mastermind of FLEXLAB," the Facility for Low-Energy eXperiments in Buildings located at Berkeley Lab.

Selkowitz is a recipient of the Berkeley Lab Prize – Lifetime Achievement Award in the area of societal impact. This award honors a career of achievement and Selkowitz was recognized for his work to reduce energy use in buildings.

EVolution. EVolution is a research project funded by the European Commission under the 7th Framework Programme of the Green Cars initiative. It started on 1 October 2012 with a specified duration of 4 years. The objective of the project was to develop new materials that will significantly reduce the weight of the new generation of hybrid and electric vehicles.

Advanced materials were used to enable the development of novel super-lightweight hybrid components complying with safety standards and recycling constraints, and enable the design to incorporate a weight reduction of 40% over that achieved using the current state-of-the-art technologies. The goal of EVolution was to demonstrate the sustainable production of a  weight FEV by the end of 2015. The base for the industrial demonstrator is the NIDO from Pininfarina.

To this end, EVolution addressed the whole vehicle by prototyping, assembling, and disassembling the most representative components. These are made from raw polymers and aluminum alloys commonly used in the automotive industry so as to ensure compliance with the End-of-Life Vehicle directive which imposes stringent requirements on the disposal and recycling of motor vehicles. The project was coordinated by Professor, PhD Jesper deClaville Christiansen, and the technical coordination by Pininfarina.

Kreidler Florett RS. Kreidler Florett RS was a German moped of Kreidler's Metall- und Drahtwerke G.m.b.H. in Kornwestheim near Stuttgart (Germany), of which 125,000 units were built between 1967 and 1981. The Florett RS was the fastest offering in the Kreidler lineup and a competent competitor to such contemporaries as the Hercules K 50 and Zündapp KS 50.

Specifications
Small motorcycles with up to 50 cm3 capacity were exempt from taxes and licence plates and could be driven with a Class 4 driving licence with a minimum age of 16 years. To stop the competitive spiral, the three leading manufacturers Kreidler, Hercules and Zündapp agreed 1970 to a voluntary limitation of the 50-cm3 class to 6,25 PS and a gearbox with a maximum of 5 gears.

BBÖ 378. The BBÖ 378 (later DRB class 93.13, then ÖBB 93) was a class of 167 Austrian 2-8-2 tank locomotives built by all four Austrian locomotive manufacturers in the 1920s and 1930s.

History
In the 1920s, the competition from road transport was already noticeable in rail operations. In particular, branch line traffic needed to be made more attractive. For this reason, the Federal Railways of Austria (Bundesbahn Österreich, BBÖ) commissioned the Floridsdorf locomotive factory with the design of a superheated steam tank locomotive, which was supposed to provide more output than the Gölsdorf 178 series and was intended to replace numerous other older series. In addition, essential components were to be standardized with the 478 series shunting locomotive, which was being developed at the same time. The branch line locomotive was given the axle formula 1′D1′ (2-8-2) and the designation 378. Without building a prototype locomotive, series production began immediately.

The machines were equipped with Lentz valve gear; attempts with other types of valve gear did not bring any advantages. Like the 178 series, they initially received solid cast disc wheels. Later deliveries returned to cast steel spoke wheels on the leading and trailing axles, and in the last series also on the driving axles. The BBÖ put 167 of this series of locomotives into operation by 1931.

From 1938, the Deutsche Reichsbahn classified the locomotives of this series as 93 1301 – 93 1467.

In 1941 the Slovak State Railways (SŽ) ordered 25 copies in a slightly different form, which were given the designation 431.0. After the Second World War these locomotives remained with the Czechoslovak State Railways (ČSD).

In 1944 the Wiener Lokalbahnen also acquired a copy of this series with a steel firebox, but it was too powerful for the tasks it was intended for, so that it was exchanged for the ÖBB 92.2256 in 1951. The ÖBB initially referred to the former WLB machine as 93.1468, but later as 93.1500.

During the Second World War, eleven locomotives were lost and a total of 28 locomotives were brought to the Yugoslav Railways (JDŽ) in Yugoslavia (partly as reparations), the remaining 128 locomotives passed to the ÖBB. In 1958, 72 units were equipped with a Giesl ejector and front-end throttle – six of them also with micro-spark arresters – which increased their performance by around 30%. The JDŽ also equipped one of its machines with a flat ejector in 1960.

The 93s were in use in the entire secondary line network of the ÖBB. It was the last standard-gauge series of steam locomotives in the ÖBB's inventory. After the official end of steam traction in Austria, some copies remained as “strategic reserves” until 1982.

Preservation
There are nineteen examples preserved at various locations including Das Heizhaus, Strasshof.

Ligier JS9. The Ligier JS9 was a Formula One racing car manufactured and raced by Ligier during the 1978 Formula One season. Driven by Frenchman Jacques Laffite, its best finish was third (twice).

Development
The JS9 was designed by Gérard Ducarouge and Michel Beaujon, with Robert Choulet working on aerodynamics. The JS9 had a large rear wing, but did not use the ground effects aerodynamics that was being developed by Lotus and other teams. The Hewland TL200 gearbox of the previous year was upgraded to the more lightweight Hewland FGA 6-speed and it continued to use the Matra MS76 V12 engine. However development of the V12 ceased during the year which may have affected the results achieved by the car.  A total of two JS9 chassis were built, with the second of these having revised suspension.

The JS9 was the last Ligier car that used a Matra V12 with the 1979 car being designed around a Cosworth engine.

Racing history
For the 1978 season, Ligier continued to run a single entry for Jacques Laffite, the team's regular driver. After completing the first six races of the season with the JS7 and JS7/9 (a hybrid car), the JS9 made its debut at the Monaco Grand Prix. Laffite qualified it fifteenth on the grid and in the race itself retired with gearbox issues. At the next race in which the JS9 ran, the Spanish Grand Prix, he finished on the podium in third, having qualified tenth. After finishing out of the points for the next three races, he finished third again in Germany, this time from seventh on the grid.

With Laffite now driving the second of the two JS9 chassis that had been built, two further points finishes were achieved, a fifth in Austria (having qualified fifth, the best starting position Lafitte achieved with the JS9) and fourth in Italy. Laffite enjoyed good reliability, retiring from just two races, Monaco and the season ending Canadian Grand Prix.

Umeå Energi. Umeå Energi is an energy company based in the town of Umeå in Sweden. It is responsible for the supply of electricity, along with providing district cooling, district heating as well as broadband services through a subsidiary by the name of UmeNet.

History 
The company was founded in 1887, reportedly due to a conversation between an engineer from London and a Swedish mayor at a wedding. Mayor Rothoff attended the wedding of steam engineer John Frederick Luth and Euphrosyne Selma Helena Grafström from Umeå. Rothoff was so impressed that he left the money to buy a Luth & Rosén steam engine. This power plant was operational in 1892 when 36 arc lights became the first electric lighting in Umeå.

In 1899 power production became more ecological when a hydro electric power unit was installed at the Ume River rapids at Baggböle. A hydro plant was built at the rapids in 1916 that supplied electricity at 40,000 volts to be used over 20 miles away. This plant was not demolished until 1958 when the plant at Stornorrfors was opened.

In 1992 Umeå Energi celebrated the centenary of electric power in Umeå by donating two restored arc lights for display at Umeå Town Hall.

Operations 

Umeå Energi has a power plant at Ålidhem that generates energy in the form of heat from various sources including household, industrial wastes and biomass. The heat generated is used to drive turbines. The company operates a second set of power plants at Dava that runs on cogeneration, or combined heat and power, thus generating power from wastes and biomass. There are two plants at Dava. The first Dava plant's main power source is burning waste which it can do at 20 tonnes per hour creating 65 MW of power. Most of this energy is used for district heating with only 10 MW create electricity. The plant also burns waste from the logging industry. Air pollution is kept to a minimum due to filtration systems on the exhaust gases. The second Dava plant creates 105 MW of power from a similar fuel mix as the other older plant, but with the addition of peat. In this case only 30MW is used for electricity. Apart from these two power stations, the company also operates a hydroelectric power plant, a wind farm, and also generates power using sewerage wastes.

The site is also home to an abandoned 100m long steel gutter that has become an iconic skateboard spot.

Phototherapy initiative 
Umeå witnesses sunrise at 9a.m. and sunset at 2p.m. during some months, thus leaving it dark for most of the day. In order to overcome this problem, in 2012 the company installed lamps in multiple bus shelters as part of a light therapy (phototherapy) initiative to minimise the effects of SAD (seasonal affective disorder). The company stated in a press release that these lamps are safe, with ultraviolet rays being filtered out, and the light is generated using power from renewable sources.

Nakajima D3N. The Nakajima D3N (also designated Experimental 11-Shi Carrier Bomber and Nakajima DB) was a Japanese carrier-based dive bomber of the 1930s. Three prototypes were built for the Imperial Japanese Navy, but no production followed, with the Aichi D3A being selected instead.

Design and development
In 1936, the Imperial Japanese Navy Air Service issued a specification for a carrier based dive bomber to replace the Aichi D1A, a two-seat biplane developed from the German Heinkel He 66. The new dive bomber was to be a low-wing monoplane, with proposals submitted by Aichi, Mitsubishi and Nakajima. Orders were placed with Aichi and Nakajima for prototypes in 1934.  Nakajima's design was based on its C3N  and B5N that had been designed to meet 1935 requirements for a reconnaissance aircraft and torpedo bomber respectively, and like these aircraft, was a single-engined monoplane of all-metal construction with folding wings for storage aboard ship. It was powered by a single Nakajima Hikari nine-cylinder radial engine, rated at , and driving a two-bladed variable-pitch propeller. It had a retractable tailwheel undercarriage, in which the mainwheels were designed to be lowered for use as dive brakes, although more conventional dive brakes were added as a result of a change in the specification.

The first prototype made its maiden flight in 1937, with the second and third prototypes flying in 1939. Aichi's AM-17 proved superior however, and was ordered into production as the Aichi D3A in December 1939.

The second prototype was retained by Nakajima and used as a testbed, helping in the development of the Nakajima Sakae and Homare engines, and remaining in use until 1945.

LCDR M2 class. The LCDR M2 class was a class of 4-4-0 steam locomotives of the London, Chatham and Dover Railway. The class was designed by William Kirtley and introduced in 1884.

History
The class were a development of Kirtley's earlier M and M1 classes intended for the London-Dover boat trains. They proved to be moderately successful for these tasks but soon needed to superseded on the heaviest trains by the larger  M3 class The locomotives passed to the South Eastern and Chatham Railway in 1899 and were considered to be sufficiently useful to be worth re-boilering between 1898 and 1903. The class began to be withdrawn and scrapped from 1912. Only one example survived into Southern Railway ownership in 1923, but was withdrawn almost immediately thereafter.

Aggregative Contingent Estimation Program. Aggregative Contingent Estimation (ACE) was a program of the Office of Incisive Analysis (OIA) at the Intelligence Advanced Research Projects Activity (IARPA).  The program ran from June 2010 until June 2015.

History

The broad program announcement for ACE was published on June 30, 2010. ACE funded the Aggregative Contingent Estimation System (ACES) website and interface on July 15, 2011. They funded The Good Judgment Project some time around July 2011. ACE has been covered in The Washington Post'''' and Wired Magazine''.  The program was concluded by late 2015. The program manager was future IARPA director Jason Gaverick Matheny.

Goals and methods

The official website says that the goals of ACE are "to dramatically enhance the accuracy, precision, and timeliness of intelligence forecasts for a broad range of event types, through the development of advanced techniques that elicit, weight, and combine the judgments of many intelligence analysts." The website claims that ACE seeks technical innovations in the following areas:

 efficient elicitation of probabilistic judgments, including conditional probabilities for contingent events
 mathematical aggregation of judgments by many individuals, based on factors that may include: past performance, expertise, cognitive style, metaknowledge, and other attributes predictive of accuracy
 effective representation of aggregated probabilistic forecasts and their distributions.

There is a fair amount of research funded by grants made by the IARPA ACE program.

Partners

The ACE has collaborated with partners who compete in its forecasting tournaments. Their most notable partner is The Good Judgment Project from Philip E. Tetlock et al. (winner of a 2013 ACE tournament) ACE also partnered with the ARA to create the Aggregative Contingent Estimation System (ACES).

Data from ACE is fed into another program, called Forecasting Science and Technology (ForeST), which partners with SciCast from George Mason University.

SciCast. SciCast is a collaborative platform for science and technology forecasting created by George Mason University with the help of a grant from the Intelligence Advanced Research Projects Activity (IARPA) as part of its ForeST (Forecasting in Science and Technology) program.  SciCast is currently (January 2016) on hiatus, after losing its main IARPA funding.  It was expected to re-open in the fall of 2015 with the support of a major Science & Technology sponsor, but this had not occurred by January 2016.

History

SciCast was an outgrowth of an earlier project called DAGGRE (Decomposition-Based Elicitation and Aggregation), also an IARPA project that implemented GMU economist Robin Hanson's idea of combinatorial prediction tech markets, and was a participant in the IARPA Aggregative Contingent Estimation tournament.

The launch of SciCast itself was announced by Robin Hanson on January 3, 2014, and the official announcements were made on January 10, 2014. The launch received some news coverage in March 2014.

Reception

SciCast has been covered in The Chicago Tribune repeatedly.

The launch of SciCast was picked up by many blogs and websites of data analysis and technology trends.
SciCast's crowdsourced search for the missing Malaysia Airlines Flight 370 airliner attracted the attention of some analysts.
