Jiro Tanaka. was a Japanese aircraft and automotive engineer.

Career

 Tanaka graduated from the Tokyo Institute of Technology in March 1939 and joined the Tachikawa Aircraft Company in April 1939. In October of the same year, he enlisted in the Army and evaluated new engines for army aircraft. In 1944, the Japanese Army sent him to his home company of Tachikawa to complete the design of the Tachikawa Ki-74. Tanaka's contribution was to add a pressurized cabin to Ki-74.

After the end of World War II, Tanaka repaired existing Tachikawa Ki-77 and Ki-74 aircraft for submission to the GHQ. 
On 30 June 1947, Tanaka joined the Tokyo Electric Car Company after it became independent from the Tachikawa Aircraft; it later changed its name to "Tama Electric Car Company" on 30 November 1949.

 After the Korean War broke out, the price of batteries rose significantly, while the price of gasoline fell. For this reason, Tama Electric Car started building gasoline-engine vehicles. As the company was essentially still an aircraft body manufacturer, they had to acquire automobile engines from outside. They bought engines from Fuji Precision Industries (one of the successors of the disbanded Nakajima Aircraft Company). Tama Electric Car changed its name to "Tama Motor Company" on November 26, 1951. In 1952, a new sedan was launched that was named "Prince," so on November 27, 1952, the company again changed its name, this time to the "Prince Motor Company."

Tanaka, as Design Department Manager, supervised the development of all Prince vehicles such as the Skyline, Gloria, and others under the supervision of his boss Ryoichi Nakagawa, a former Nakajima Aircraft engineer. Tanaka was promoted to executive director after Prince Motor Company mergered with Nissan. He retired from Nissan in 1983, and was appointed the Vice President of Nissan Diesel. In 1985, Tanaka retired from Nissan Diesel but remained an adviser to the company. He was inducted into the Japan Automotive Hall of Fame in 2008 along with Yutaka Katayama, also known as "Mr. K".

Death
Jiro Tanaka died in 2017, at the age of 100.

ObjecTime Developer. ObjecTime Developer (or ObjecTime or OTD, for short) is a software automation tool designed to meet the development needs of real-time software development teams. The tool was created by ObjecTime Limited of Kanata, Ontario, and was aimed at aiding software developers in building applications using Real-Time Object-Oriented Modeling (ROOM) for real-time, graphical design models. ObjecTime, using the design models, will then generate production-quality applications for real-time operating systems, using the C and C++ programming languages. An important aspect of the development process using OTD was the capability to visually see the execution of the generated software as animation of the design models. This was true both for the software running both on the development or target platform.

The concepts behind the modeling language described in ROOM (actors and structure/state) was gradually incorporated into UML, first as a profile for real-time (capsules and structure/state) and then as an integral part of UML 2 (composite classes).

When Rational Software acquired ObjecTime Limited in 2000  their respective products — Rational Rose and ObjecTime Developer — were then merged into a product that was rechristened Rational Rose RealTime. This major changes resulted in the loss of a commercial implementation of ROOM. Today only the recently started Eclipse open source project eTrice is implementing ROOM.

Schütte-Lanz D.VI. The Schütte-Lanz D.VI was a single engine, parasol wing fighter aircraft designed and built in Germany towards the end of World War I.  It had a very short career, crashing on its first flight.

Design

The wing of the D.VI was of constant chord, with straight edges and square tips.  It was mounted with slight sweep over the fuselage, parasol fashion, primarily braced by a pair of long parallel struts on each side from the lower fuselage to points well out along the wings. It was supported centrally on two outward leaning pairs of short parallel cabane struts from the upper fuselage. Unusually the space between each main strut pair was faired-in with a lift-providing aerofoil, supplementing the wing.  These surfaces extended from the lower fuselage strut junction to the level of the cockpit and upper fuselage, the rest of the struts being normally exposed.

The D.VI was powered by a  Mercedes D.III water cooled six cylinder inline engine.  The fuselage behind was rectangular in cross section and flat sided, with the single cockpit under the wing trailing edge where there was a small cut-out to aid the pilot's vision.  The tailplane was placed on top of the fuselage and like the vertical tail was essentially straight edged.  The rudder was balanced and extended down to the keel, moving in a cut-out between the elevators. The fixed conventional undercarriage had a single axle mounted on a pair of V-struts, aided by a sprung tailskid.

Its first flight was on 29 May 1918.  It crashed and was seriously damaged, but never rebuilt.

Energiekontor. Energiekontor is a German company specialized in the development and management of wind farms and solar parks. The main activities are concentrated in Germany, Portugal and in the United Kingdom. The company sells developed facilities or takes the ownership. Energiekontor manages external wind farms for clients as well.

Achievements and market presence 
Until May 2018, Energiekontor had built 118 wind farms with a total rated power of nearly 940 MW. The electricity generated by this facilities amounts to ca. 2 billion kWh per year which comes up to the demand of more than 600,000 households. The capital invested totals more than €1.6 billion.

Energiekontor itself owns and operates 34 wind farms and one solar park with a total rated power of nearly 259 MW in Germany, Portugal and in the UK (end of 2017). In addition to its headquarters in Bremen, the company has five offices in West, North and East Germany. Branch offices were established in Leeds (England), Glasgow (Scotland), Lisbon (Portugal), Nijmegen (Netherlands), Austin/Texas (US) and Toulouse (France).

Innovation 

Energiekontor also develops new technologies and methods to improve efficiency and reliability of wind power facilities. Particular importance has been the Rotor Blade Extension (RBE), presented in 2009 together with the university of Bremerhaven. By increasing the rotor diameter with an additional modular segment that is applied over the blade tip, yield grows significantly. The extension modules for two AN Bonus turbines (1.0 and 1.3 MW) are specified with an Annual Energy Production (AEP) increase of 5 to 7%. Energiekontor indicates a payback period of three years and recommends the solution as an alternative to repowering especially in countries with limited grid access. In December 2016, the company announced a new prototype for GE 1.5sl turbines (1.5 MW) with an expected AEP increase of around 9.5%.

History 

Energiekontor was founded in 1990 by Bodo Wilkens and Günter Lammers on the basis of the German Electricity Feed-in Act, a precursor of the Renewable Energy Sources Act (EEG). The first two wind farms, located in Lower Saxony, were built in 1994. In 2000, Energiekontor had a track record of around 200 MW and went public. In 2005, the first wind farm in UK was taken into operation.

Beginning in the late 1990s, Energiekontor also developed two offshore wind farms in the German North Sea. Borkum Riffgrund West was approved in 2004, Nordergründe in 2007. The rights for these projects were sold between 2011 and 2014 to DONG Energy and . Thereby, the company carried out its pull back from all offshore activities.

In 2010, Energiekontor started to develop solar parks with photovoltaic panels. In 2016, the company entered the Dutch market. In 2017, further market entries followed in France and in the US.

Environmental Criminology Research. Environmental Criminology Research Inc. (ECRI) is a crime analysis software company based in Vancouver, British Columbia, Canada.  The company develops tools for police, military and security use. ECRI pioneered the use of geographic profiling software for serial crime analysis.

Rigel Software 

ECRI’s Rigel software was first introduced in 1997
and is based on the doctoral dissertation of Dr. Kim Rossmo, who co-founded ECRI. Rossmo’s criminal geographic targeting (CGT) model, which produces a “probability surface” that shows the relative likelihood of the offender’s base of operations, is patented. Users of the Rigel software include the national police agencies of Canada, the United States, and several European nations, as well as many smaller regional and local police forces.

The software utilizes data such as crime locations, suspect information, case details and investigator details to analyze a series of linked crimes and determine the most probable locations of the offender's residence.  This allows investigators to prioritize suspects and focus on areas they may have otherwise overlooked.  This process has proven successful in helping to solve many crime series around the globe.

Notable Uses 
Rigel was used as a tool during the Beltway sniper attacks case that took place in October 2002 in Washington, D.C., Maryland, and Virginia.  Rigel was also directly involved in helping the Irvine Police Department apprehend Raymond Lopez, who is known as the "Chair Burglar". In hundreds of burglaries, Lopez had the same routine of placing a chair or potted plant next to a home's fence for a quick, easy escape.  Rigel identified Lopez as a suspect of interest and he was put on surveillance eventually leading to his arrest. For their work on this case the Irvine Police Department won The International Association of Chiefs of Police (IACP) Choicepoint Award for Excellence in Criminal Investigation.

Walter Mellor. Walter Mellor (1880–1940) was an American architect.

Biography

Early life
He was born on April 25, 1880, in Philadelphia, Pennsylvania. His father was Alfred Mellor and his mother, Isabella (Latham) Mellor. He graduated from The Haverford School in Haverford, Pennsylvania in 1897 and received a Bachelor of Science in Mechanical Engineering from Haverford College in 1901. He then earned a Bachelor of Science in architecture from the University of Pennsylvania in 1904. He was a member of the Phi Gamma Delta fraternity.

Career
Shortly after graduation, he worked for Theophilus P. Chandler Jr. (1845-1928), where he met Arthur Ingersoll Meigs (1882-1956). In 1906, they started their own architectural firm, with offices in the Lafayette Building. They worked on alterations of the Pickering Hunt Club in Phoenixville, Pennsylvania in 1911 and the Princeton Charter Club in Princeton, New Jersey in 1913. They also designed fraternity houses for Phi Gamma Delta and Haverford College.

In 1916, George Howe (1886–1955) joined their practice, which became Mellor Meigs & Howe. Together, they designed a branch office building for the Philadelphia Savings Fund Society. They also designed Phi Gamma Delta fraternity house at the University of Washington located at 5404 17th Avenue NE University District in Seattle, Washington. In 1922, the firm won an award from the Philadelphia chapter of the American Institute of Architects for the McCracken residence in Germantown, Philadelphia, and in 1925, the Gold Medal of the Architectural League of New York for the Newbold Estate development. In 1928, Howe left the practice.

Blaisdell Slow Sand Filter Washing Machine. The Blaisdell Slow Sand Filter Washing Machine at Yuma, Arizona is a device invented by Hiram W. Blaisdell to wash sand filters used in the treatment of drinking water. The machine was built in 1902 at Blaisdell's privately operated waterworks, which treated the muddy water of the Colorado River for local consumption. Blaisdell patented the device and marketed it throughout the United States. The Yuma filter is now on City of Yuma property, and has been preserved as the first of its kind.

Description
The Blaisdell machine traveled along steel tracks laid on top of the walls of rectangular filter basins, bridging the walls with its structure. The washing chamber was lowered from the moving bridge frame into the basin. The chamber measures about wide,  deep and  long, and contains a  diameter circular washing unit. The washing unit stirred the surface of the sand bed, dislodging sediment and flushing it away through two suction pumps at the top of the box, avoiding contamination of the surrounding water. The mechanism was controlled by an operator in a corrugated metal enclosure.

The Blaisdell machine was placed on the National Register of Historic Places on January 18, 1979.

Curb mining. Curb mining is the act of salvaging appliances, electronics, furniture and art discarded on the street ("curbside"). In cities around the world, people often dispose of furniture and other unwanted items by leaving them on the sidewalk for others to take.

Description 
Curb mining is the act of salvaging appliances, electronics, furniture and art discarded on the street ("curbside"). In cities around the world, people often dispose of furniture and other unwanted items by leaving them on the sidewalk for others to take.

Terminology 
Terms similar to curb mining include "dumpster diving" and "freeganism". In June 2007, The New York Times wrote:

Re-use and recycling 
In many jurisdictions, ownership of domestic waste changes once it is placed into a container for collection. It is thus illegal (although rarely enforced) to skip dive. Curb mining gets round this because the items offered are not yet placed (in a legal sense) into the "waste" stream, thus their ownership has not yet been transferred. It is often legal to curb mine, but illegal to skip dive.

Some countries—notably Germany, Japan, and much of Western mainland Europe—have a long tradition that items placed outside are intended specifically for re-use by others. There may be a designated day of the week or month, distinct from normal refuse collections, to encourage this.

Marketing 
The urban phenomenon of curb mining has been used by various companies for experimental marketing. The strategy is to create awareness of a product by handing it out for free. In 2009, advertising agency Mono and modern furniture designer Blu Dot created an experiment to see what would happen if they left 25 Blu Dot chairs on the street for "curb miners" to find. They attached GPS devices to the chairs, which were activated once the chairs were picked up and taken.  The chairs were then tracked back to the new owners' homes where a handful of them were interviewed for a documentary.
