Entomovector. An entomovector is a pollinating insect used as a vector to spread a substance used in the biocontrol of plant pests and diseases. The insect is typically a honey bee, bumblebee, or mason bee, but may be any variety of insect that spreads pollen among plants. The choice of vector species is decided by a combination of native species in the area to be pollinated, the plant species to be treated, and the ease of care of the vector species.

The substance is typically a powdered substance containing a virus, bacterium, or fungus to be used to protect the host plant from a given disease or pest. The insect, or vector, is typically exposed to this material by placing a tray containing the powder at a hive exit or by using fans to blow it into the hive.

Addis Ababa City Hall. The Addis Ababa City Hall ()  is a governmental department that houses the offices of the Municipality of Addis Ababa, Ethiopia.

History
Along with Africa Hall, the UNECA headquarters, the Addis Ababa city hall was one of the two projects designed to demonstrate, in the words of Emperor Haile Selassie, “that it is possible to construct grand buildings here too [in Ethiopia], by erecting a couple of high-profile structures. It is not their complexity or size that matter, but the maximum possible use of home-produced materials, in order to shake our wealthy middle class (which keeps its money under the mattress) from the inactivity that also binds it in the field of construction, and stimulate it to invest its assets also in building to make this ‘great village’ a city and a true great capital”.  Construction commenced in 1961 and was completed in 1964. Queen Elizabeth II received the freedom of the city on 4 February 1965 in a ceremony here, and attended a banquet in her honour that day.

Features
The structure is situated at the northern end of Churchill Avenue, and is a direct consequence of the avenue's re-routing, sitting on top of a hill overlooking the thoroughfare. The structure features various spaces – the hall, boardroom, reception room, cinema-theatre, restaurant, 4 bars, library, and panoramic terrace – making it a social as well as an administrative centre.

James Thorneloe Smith. James Thorneloe Smith M.Inst C.E., (20 August 1825 –  14 March 1902) was an engineer and  politician in colonial Queensland, a member of the Queensland Legislative Council.

Early life 
Smith was the son of the Rev. William Smith, Wesleyan minister, was born in Chester and educated at Woodhouse Grove School, near Leeds.

Engineering career 
Smith arrived in Victoria (Australia) in 1852, and entered the Civil Service of that colony as a railway surveyor in the same year. Upon a reduction being made in the staff, he went to Queensland in November 1862, and after twelve months' exploration in the interior, entered the Queensland Civil Service and surveyed the upper portion of the main range above Murphys Creek. In 1865 Mr. Smith constructed the railway from Toowoomba to Warwick, Queensland and afterwards became chief engineering surveyor of the Railway Surveys Department, and surveyed Cooktown and the interior with a view to possible railway construction. In 1873 he was appointed by the Arthur Macalister Administration Chief Engineer of the South and West Railway system, and was Acting Chief Engineer for twelve months, during the absence of Mr. Stanley, who then held that post. He then acted as Deputy Engineer-in-chief of the South and West Railways until the abolition of the office by the Samuel Griffith Ministry in July 1884.

Politics 
Smith was appointed to the  Queensland Legislative Council on 23 August 1888 and remained a member until his death.

Personal life 
Smith married Pauline Eliza  Marks in Melbourne on 31 October 1852.

He died in Brisbane on 14 March 1902 following several months of poor health. As he had requested, he was buried at Helidon alongside his brother William Smith, following a graveside funeral service. His coffin was carried by train from Brisbane, where he was farewelled by railway officials to Helidon, where gangers who had worked under him on the Toowoomba railway carried his coffin to the cemetery.

Émile Jaboulay. Émile Jaboulay (14 February 1879 – 28 January 1961) was a French chemist and metallurgist.

Émile Jaboulay was born in Rive-de-Gier on 14 February 1879, son of an engineer. His higher education led to his becoming a chemist.
He became a chemical engineer at the marine steel works in Lorette, and then set up and directed the first laboratory for the Société d'Electro-Chimie, d'Electro-Métallurgie et des Aciéries Electriques d'Ugine (SECEMAEU), a factory founded by the industrialist Paul Girod and better known by the name of Ugitech.
In 1909 he founded his own company, the Jaboulay steelworks at Terrenoire (now part of Saint-Étienne).
He directed this company until 1947.

Émile Jaboulay specialized in research into alloys, and conducted more than 10,000 tests between 1910 and 1923.
Based on these results his business in Terrenoire produced and marketed high-carbon steel that had great value in high-speed steel tools. 
High-carbon steel was requisitioned during World War II to make German tanks and airplanes.

Jaboulay was made a knight of the Legion of Honor in 1959.
Émile Jaboulay died in Saint-Étienne on 28 January 1961.
A street in Saint-Étienne is named after him.

Chaplygin sleigh. The Chaplygin sleigh is a simple pedagogical example of a nonholonomic system in mechanics, described by Sergey Chaplygin. It consists of a body that slides frictionlessly on a horizontal plane, with a knife edge that constrains its motion so that the knife slides only longitudinally. Because this constraint is nonholonomic, Liouville's theorem does not apply, and although energy is conserved, the motion is dissipative in the sense that phase-space volume is not conserved. The motion is attracted to an equilibrium, in which the sleigh moves without rotation, with the knife edge trailing the center of mass.

There are several ways of seeing that the system is nonholonomic. The dimension of the phase space is 5, which is odd. The constraint on the velocity is not derivable from a constraint on the coordinates.

The motion of the system can be characterized simply. Let v be the velocity, with positive values indicating that the knife edge trails. Let ω be the angular velocity. Then the equations of motion are

where a is the distance between the center of mass and contact point which is frequently the front of the sleigh, I is the moment of inertia, and m is the mass. The solutions are ellipses in the v–ω plane. The equations of motion are symmetric under time reversal, but asymmetric under inversion of the body-fixed axis aligned with the knife edge.

In geometric mechanics, the Chaplygin sleigh lives in the special Euclidean group  since the position and direction are accounted for.

The analogue of the Chaplygin sleigh is the torpedo. Now, the body glides frictionlessly through space rather than the plane. The system is constrained to slide only longitudinally and cannot twist around the direction of motion similar to how a torpedo moves through water. The dimension of the phase space is 9 since there are 6 positions and 6 velocities coupled with 3 constraints. This system is the natural analogue to the Chaplygin sleigh since it lives in .

Open Infrastructure Architecture method. The Open Infrastructure Architecture method, or OIAm, is an open standard for the application of architecture to infrastructure.

OIAm and the community
The development of the method has from its early inception been published on the Internet under a Creative Commons license, using a Semantic MediaWiki based wiki for publication of standard content - originally the "DYA|Infrastructure Repository" (DIR),
currently the "Open Infrastructure Architecture repository" (OIAr). As a result of this, a community evolved consisting of architects and other people working with, or being interested in, the method. This community mainly revolves around the aforementioned OIAr, a LinkedIn group named Open Infrastructure Architecture, and a semi-annual community meeting.

Neural Engineering Object. Neural Engineering Object (Nengo) is a graphical and scripting software for simulating large-scale neural systems. As the neural network software Nengo is a tool for modelling neural networks with applications in cognitive science, psychology, artificial intelligence and neuroscience.

History 
Some form of Nengo has existed since 2003. Originally developed as a Matlab script under the name NESim (Neural Engineering Simulator), it was later moved to a Java implementation under the name NEO, and then eventually Nengo. The first three generations of Nengo developed with a focus on developing a powerful modelling tool with a simple interface, and scripting system. As the tool became increasingly useful the limitations of the system in terms of speed led to development of a back-end agnostic API. This most recent iteration of Nengo defines a specific Python-based scripting API with back-ends targeting Numpy, OpenCL and Neuromorphic hardware such as Spinnaker. This newest iteration also comes with an interactive GUI to help with the quick prototyping of neural models.

Nengo uses a custom license which allows free personal and research use, but a paid license is required for commercial purposes.

Theoretical Background 

Nengo is built upon two theoretic underpinnings, the Neural Engineering Framework (NEF) and the Semantic Pointer Architecture (SPA).

Neural Engineering Framework 

Nengo differs primarily from other modelling software in the way it models connections between neurons and their strengths. Using the NEF, Nengo allows defining connection weights between populations of spiking neurons by specifying the function to be computed, instead of forcing the weights to be set manually, or use a learning rule to configure them from a random start. That being said, these aforementioned traditional modelling methods are still available in Nengo.

Semantic Pointer Architecture 

To represent symbols in Nengo, SPA is used. Many aspects of human cognition are easier to model using symbols. In Nengo, these are presented as vectors with a set of operations associated to them. These vectors and their operations are called SPA. SPA has been used to model human linguistic search and task planning.

Applications 

Notable developments accomplished using the Nengo software have occurred in many fields, and Nengo has been used and cited in over 100 publications. An important development to note is Spaun, a network of 6.6 million artificial spiking neurons (a small number compared to the number in the human brain), which uses groups of these neurons to complete cognitive tasks via flexible coordination. Spaun is the world's largest functional brain model, and can be used to test hypotheses in neuroscience.
