Starfire video prototype. Starfire was a Sun Microsystems promotional video filmed in 1994, demonstrating Bruce Tognazzini's ideas for a 21st-century computer user interface. Inspired in part by Apple Computer's Knowledge Navigator film from 1987, Tognazzini and his team at SunSoft sought to create a more realistic look at how computer technology and interfaces would improve. The project drew together the talents of more than 100 engineers, designers, futurists, and filmmakers in an effort to both predict and guide the future of computing.

The film is set in the year 2004 and features a protagonist interacting by voice, mouse, and stylus with a  . The story concerns an executive at an auto-maker who must make a compelling presentation for her design.

In the video's boardroom scene, it predicts the rise of a new technology similar to what is now known as the World Wide Web.

Popular Science Magazine reported, in March 2009, that Microsoft had just produced a new video showing life in the year 2019: "The 2019 Microsoft details with this video is almost identical to the 2004 predicted in this video produced by Sun Microsystems in 1992."

In addition to the film, the project also produced:
 Tog on Software Design, which not only covers the film in intimate detail, but lays out several more equally thought-provoking scenarios, even if they were not enshrined in celluloid.
 Starfire, the Paper, published in the CHI Proceedings, outlining the rules followed in attempting to build a scientifically legitimate video prototype, as opposed to simply confabulating a fanciful, but non-implementable, vision.

The film was released as the Starfire video, in NTSC format, and later made available as part of a collection of human-computer interaction videos.

Glaser-Dirks DG-200. The Glaser-Dirks DG-200 is a 15 metre class glider built by Glaser-Dirks, now DG Aviation GmbH

Design started in 1976, and it first flew in 1977. 

Wingtip extensions to 17 metres were offered in 1978. Later enhancements included a single-piece canopy, a carbon-fibre wing spar and a change in the wing profile. A total of 192 DG-200 were built.

The glider design includes:

 a two-piece conventional elevator, with a fixed forward stabilizer and aft-mounted movable elevator
 a control stick with a parallelogram linkage to reduce pilot-induced oscillations
 Schempp-Hirth airbrakes on top surface only
 a 5"x5" main wheel (drum brake) and a 200x50 tail wheel
 l'Hottelier connection for the ailerons, airbrakes and elevator (elevator connection is automatic on the DG-202). Flaps connection is automatic.

According to Dick Johnson in his Flight Test Evaluation of the DG-200 published in the Soaring Magazine in July 1980:

"The sailplane is a real beauty to behold with its excellent finish and sleek pointed nose. The canopy is exceptionally good, and it provides outstanding forward visibility for the pilot. The cockpit is outstandingly good for moderately sized pilots; I have never flown a sailplane that was more comfortable. I flew several 5 and 6-hour flights in the DG-200 with no discomfort whatsoever."

The DG-400 motor glider was derived from the DG-202/17C.

It belongs to the same generation as the Rolladen-Schneider LS3, Alexander Schleicher ASW 20, Schempp-Hirth Mini-Nimbus, Eiri-Avion PIK-20 and Glasflügel Mosquito.

Equilibrium thermodynamics. Equilibrium Thermodynamics is the systematic study of transformations of matter and energy in systems in terms of a concept called thermodynamic equilibrium.  The word equilibrium implies a state of balance.  Equilibrium thermodynamics, in origins, derives from analysis of the Carnot cycle.  Here, typically a system, as cylinder of gas, initially in its own state of internal thermodynamic equilibrium, is set out of balance via heat input from a combustion reaction.  Then, through a series of steps, as the system settles into its final equilibrium state, work is extracted.    

In an equilibrium state the potentials, or driving forces, within the system, are in exact balance. A central aim in equilibrium thermodynamics is: given a system in a well-defined initial state of thermodynamic equilibrium, subject to accurately specified constraints, to calculate, when the constraints are changed by an externally imposed intervention, what the state of the system will be once it has reached a new equilibrium.  An equilibrium state is mathematically ascertained by seeking the extrema of a thermodynamic potential function, whose nature depends on the constraints imposed on the system. For example, a chemical reaction at constant temperature and pressure will reach equilibrium at a minimum of its components' Gibbs free energy and a maximum of their entropy.

Equilibrium thermodynamics differs from non-equilibrium thermodynamics, in that, with the latter, the state of the system under investigation will typically not be uniform but will vary locally in those as energy, entropy, and temperature distributions as gradients are imposed by dissipative thermodynamic fluxes.  In equilibrium thermodynamics, by contrast, the state of the system will be considered uniform throughout, defined macroscopically by such quantities as temperature, pressure, or volume.  Systems are studied in terms of change from one equilibrium state to another; such a change is called a thermodynamic process.

Ruppeiner geometry is a type of information geometry used to study thermodynamics. It claims that thermodynamic systems can be represented by Riemannian geometry, and that statistical properties can be derived from the model. This geometrical model is based on the idea that there exist equilibrium states which can be represented by points on two-dimensional surface and the distance between these equilibrium states is related to the fluctuation between them.

Northwest Territories Power Corporation. The Northwest Territories Power Corporation (NTPC) is an electric utility in the Northwest Territories of Canada. NTPC was formed in 1988 to acquire and operate the former assets of the Northern Canada Power Commission in the Northwest Territories, including what is now Nunavut. Since 2007, NTPC is organized as a subsidiary of the Northwest Territories Hydro Corporation.

76% of NTPC's electrical generation is in the form of Hydro electricity. Hydro production has increased approximately 15% since 1990/91, reducing demand on diesel production and lower GHG emissions by 58% of 1990/91 levels.  This has led NTPC to be recognized as a Gold Champion Level Reporter by the Canadian voluntary Challenge and Registry for seven consecutive years, including a leadership award and an honourable mention.
 
NTPC sells electricity wholesale to Northland Utilities, a private company majority-owned by ATCO, which provides electricity in Yellowknife and Hay River. Liquid natural gas and diesel are used to generate electricity in Inuvik. All other communities served by NTPC generate power using diesel.

Synergetics (Haken). Synergetics is an interdisciplinary science explaining the formation and self-organization of patterns and structures in open systems far from thermodynamic equilibrium. It is founded by Hermann Haken, inspired by the laser theory. Haken's interpretation of the laser principles as self-organization of non-equilibrium systems paved the way at the end of the 1960s to the development of synergetics. One of his successful popular books is Erfolgsgeheimnisse der Natur, translated into English as The Science of Structure: Synergetics.

Self-organization requires a 'macroscopic' system, consisting of many nonlinearly interacting subsystems. Depending on the external control parameters (environment, energy fluxes) self-organization takes place.

Order-parameter concept
Essential in synergetics is the order-parameter concept which was originally introduced in the Ginzburg–Landau theory in order to describe phase transitions in thermodynamics. The order parameter concept is generalized by Haken to the "enslaving-principle" saying that the dynamics of fast-relaxing (stable) modes is completely determined by the 'slow' dynamics of, as a rule, only a few 'order-parameters' (unstable modes). The order parameters can be interpreted as the amplitudes of the unstable modes determining the macroscopic pattern.

As a consequence, self-organization means an enormous reduction of degrees of freedom (entropy) of the system which macroscopically reveals an increase of 'order' (pattern-formation). This far-reaching macroscopic order is independent of the details of the microscopic interactions of the subsystems. This supposedly explains the self-organization of patterns in so many different systems in physics, chemistry and biology.

Slope mining. Slope mining is a method of accessing valuable geological material, such as coal or ore.  A sloping access shaft travels downwards towards the desired material. Slope mines differ from shaft and drift mines, which access resources by tunneling straight down or horizontally, respectively.  In slope mining, the primary access to the mine is on an incline.  Mine hoists may still be used to raise and lower loads on the incline if it is steep, but on shallower slopes, conveyor belts, locomotives or trucks may do the work.  Drainage and ventilation of slope mines may be done using the primary slope, or it may be done using auxiliary shafts or bore-holes.

Dielectric complex reluctance. Dielectric complex reluctance is a scalar measurement of a passive dielectric circuit (or element within that circuit) dependent on sinusoidal voltage and sinusoidal electric induction flux, and this is determined by deriving the ratio of their complex effective amplitudes. The units of dielectric complex reluctance are  (inverse Farads - see Daraf) [Ref. 1-3].

   

As seen above, dielectric complex reluctance is a phasor represented as uppercase Z epsilon where:
  and  represent the voltage (complex effective amplitude)
  and  represent the electric induction flux (complex effective amplitude)
 , lowercase z epsilon, is the real part of dielectric reluctance

The "lossless" dielectric reluctance, lowercase z epsilon, is equal to the absolute value (modulus) of the dielectric complex reluctance. The argument distinguishing the "lossy" dielectric complex reluctance from the "lossless" dielectric reluctance is equal to the natural number  raised to a power equal to:

 

Where:
 is the imaginary unit
 is the phase of voltage
 is the phase of electric induction flux
 is the phase difference

The "lossy" dielectric complex reluctance represents a dielectric circuit element's resistance to not only electric induction flux but also to changes in electric induction flux.  When applied to harmonic regimes, this formality is similar to Ohm's Law in ideal AC circuits. In dielectric circuits, a dielectric material has a dielectric complex reluctance equal to:

Where:
 is the length of the circuit element
 is the cross-section of the circuit element
 is the complex dielectric permeability
