DuPont Aerospace DP-1. 

The DuPont Aerospace DP-1 was a subscale prototype for a fixed-wing VSTOL transport aircraft, intended to take off and land like a helicopter and fly like an airplane. The fullscale aircraft, named DP-2, was designed to travel at high subsonic speeds with a greater range than its rotary-wing equivalent, and to allow troops to rappel from the aft cargo ramp. The development of the 53% scale DP-1 aircraft was originally funded in the early 1990s as a backup to the V-22 Osprey program, which was undergoing significant technical and political challenges.  During the construction of the test aircraft, program management changed the requirements, and mandated that the vehicle be tested as a UAV.  This change added significant cost and time to the project, but in September 2007, the DP-1 autonomous prototype achieved sustained, controlled tethered hovers of 45 seconds at the Gillespie Field test site.

On June 13, 2007, the U.S. House Committee on Science and Technology held a hearing about the fate of the DP-2. In August 2007, funding was finally cut, after a total of $63 million spent over nearly two decades.

Spatiotemporal Epidemiological Modeler. The Spatiotemporal Epidemiological Modeler (STEM) is free software available through the Eclipse Foundation. Originally developed by IBM Research, STEM is a framework and development tool designed to help scientists create and use spatial and temporal models of infectious disease. STEM uses a component software architecture based on the OSGi standard. The Eclipse Equinox  platform is a reference implementation of that standard. By using a component software architecture, all of the components or elements required for a disease model, including the code and the data are available as software building blocks that can be independently exchanged, extended, reused, or replaced. These building blocks or plug-ins  are called eclipse "plug-ins" or "extensions". STEM plug-ins contain denominator data for administrative regions of interest. The regions are indexed by standard (ISO3166) codes.

STEM currently includes a large number of plug-ins for the 244 countries and dependent areas defined by the Geographic Coding Standard maintained by the International Organization for Standardization.  These plug-ins contain global data including geographic data, population data, demographics, and basic models of disease. The disease models distributed with STEM include epidemiological compartment models. Other plug-ins describe relationships between regions including nearest-neighbor or adjacency relationships as well as information about transportation, such as connections by roads and a model of air transportation.

Relationships between regions can then be included in models of how a disease spreads from place to place. To accomplish this, STEM represents the world as a "graph". The nodes in the graph correspond to places or regions, and the edges in the graph describe relationships or connections between regions. Both the nodes and the edges can be labeled or "decorated" with a variety of denominator data and models. This graphical representation is implemented using the Eclipse Modeling Framework (EMF). Since a model can be built up using separate subgraphs, STEM enables model composition. Predefined subgraphs defining different countries can be assembled with a drag and drop interface.  New disease vectors can simply be added to existing models by augmenting the model with a new set of edges. The architecture also supports collaboration as users can not only create new models and compose new scenarios but also exchange these models and scenarios as reusable components and thereby build on each other's work. As an open source project, users are encouraged to create their own plug-ins (both data and models) and, if appropriate, to contribute their work back to the project.

Lake Olomega. Lake Olomega is a large lake in the southeastern part of El Salvador.

In the past few years Lake Olomega has suffered from an infestation of Water hyacinth which has caused problems for wildlife, fishing, and tourism.

Lake Olomega is located next to the town of Olomega (population 4000).  The community relies heavily on fishing and ecotourism.  The canton Los Riitos has geothermal water and can most easily be reached by boat (as long as the nimfa does not prevent boat travel).

For years this natural resource has received the black waters of the settlements to their round, pollution by livestock and fisheries hasn't been unregulated. With Ramsar status, the Government can make sustainable development in the area, thanks to international support.

Olomega is the eastern region of El Salvador's, largest freshwater body. The site also includes the surrounding vegetation, such as herbaceous swamps and a patch of forest seasonally saturated, known as the Chiriqui and one of the last relics of this type of community in El Salvador

The hydrological features of the site include flood control, water purification, and the replenishment of groundwater, serving for more than 9,000 inhabitants of the area.

Rich biodiversity

An electronic report of the Ramsar Convention details show that the lagoon is home to several endangered species, such as the royal duck, dark ibis, the snail and the tree frog.

This wetland, which measures 7,557 hectares, serves as the resting and feeding ground for many migratory birds.

Transportation
Olomega can be reached either by taking a bus directly to the town, although the bus to Olomega does not run often, or by getting off at El Carmen (the pueblo, just off the highway) and waiting for a truck to go to Olomega.  tambien puedes entrar por el lado de puerto viejo

Bede BD-7. 

The Bede BD-7 was a light aircraft constructed in the United States in 1976.  It shared the Bede BD-5's pusher propeller configuration but was considerably larger.  The fuselage was all-metal, and the wings used the unique "panel-rib" wing construction pioneered on the Bede BD-4.  Some sources state that the prototype (registration N7BD) flew in December 1976, but most suggest that it was never actually completed, much less flown.

The Mutant Virus: Crisis in a Computer World. The Mutant Virus: Crisis in a Computer World is an NES video game produced by ASC Games. It was made in April 1992.

Gameplay

The plot centers around protagonist, Ron, and his fight to eliminate a virus out of a global A.I. that is responsible for every aspect of technology in the game's present day. If Ron is unable to extinguish the virus, humanity will be thrown back to the Stone Age. The player controls a miniature "space ship" which shoots anti-virus and other variations of the weapon to try to contain the virus in that room.

The virus in the game is a cellular automaton following the rules of Conway's Game of Life, with the exception that each cell is either a virus cell (green) or a clean cell (light blue). As new cells are made, they either become virus cells or clean cells depending on which type makes up the majority of their neighbors.

Scattering from rough surfaces. Surface roughness scattering or interface roughness scattering is the elastic scattering of particles against a rough solid surface or imperfect interface between two different materials.  This effect has been observed in classical systems, such as microparticle scattering, as well as quantum systems, where it arises electronic devices, such as field effect transistors and quantum cascade lasers.

Classical description
In the classical mechanics framework, a rough surface, such as a machined metal surface, randomizes the probability distribution function governing the incoming particles, leading to net momentum loss of the particle flux.

Quantum description

In the quantum mechanical framework, this scattering is most noticeable in confined systems, in which the energies for charge carriers are determined by the locations of interfaces.  An example of such a system is a quantum well, which may be constructed from a sandwich of different layers of semiconductor.  Variations in the thickness of these layers therefore causes the energy of particles to be dependent on their in-plane location in the layer.  Classification of the roughness at a given position, , is complex, but as in the classical models, it has been modeled as a Gaussian distribution by some researchers  
This assumption may be formulated in terms of the ensemble average for some given characteristic height, , and correlation length, , such that

Types of Scattering 
Selective Scattering : In selective Scattering scattering depends upon the wavelength of light.

Mie scattering : Mie theory can describe how electromagnetic waves interact with homogeneously spherical particles. However, a theory for homogeneous spheres will completely fail to predict polarization effects. When the size of the molecules is greater than the wavelength of light, the result is a non-uniform scattering of light.

Lambertian Scattering: This type of scattering occurs when a surface has microscopic irregularities that scatter light perfectly uniformly in all directions, causing it to appear equally bright from all viewing angles.

Subsurface Scattering: This type of scattering occurs when light scatters within a material before exiting the surface at a different point.

Isotropic crystal scattering (aka powder diffraction): This type of scattering occurs when every crystalline orientation is represented equally in a powdered sample. Powder X-ray diffraction (PXRD) operates under the assumption that the sample is randomly arranged such that each plane will be represented in the signal.

Dialyte lens. A dialyte lens (sometimes called a dialyt) is a compound lens design that corrects optical aberrations where the lens elements are widely air-spaced. The design is used to save on the amount of glass used for specific elements or where elements can not be cemented because they have dissimilar curvatures. The word dialyte means "parted", "loose" or "separated" in Greek.

Design
In its simplest form, a dialyte can be formed by separating the elements in a cemented achromatic doublet of positive and negative lenses, although the powers of the individual elements must be increased to compensate.

Applications

Telescopes
The idea of widely separating the color correcting elements of a lens dates back to W. F. Hamilton's  1814 catadioptric Hamiltonian telescope and Alexander Rogers' 1828 proposals for a dialytic refractor. The goal was to combine a large crown glass objective with a much smaller flint glass downstream to make an achromatic lens since flint glass at that time was very expensive. Dialyte designs were also used in the Schupmann medial telescope designed by in German optician Ludwig Schupmann near the end of the 19th century, in John Wall's 1999 "Zerochromat" retrofocally corrected dialytic refractor and the Russian made "TAL Apolar125" telescope which uses 6 elements arranged in three widely separated groups.

Photography

There are many types of dialyte camera lenses. One popular design is perfectly symmetric, which provides good correction for many aberrations. This consists of two air-spaced achromatic doublets arranged back-to-back around a central stop, or four air spaced lens elements in total: the outer pair is biconvex and the inner pair is biconcave; one example is the Celor. The Swiss mathematician Emil von Höegh, who had designed the popular Dagor anastigmat lens for Goerz in 1892, continued to refine that design, resulting in the Goerz Dagor Type B lens of 1899, later renamed to Celor and Syntor.

The Aviar lens (Taylor Hobson) designed by Arthur Warmisham (1917) is similar but is considered to have a different origin, from the splitting of the central biconcave element of the Cooke triplet. The resulting two biconcave elements are closer together than in the Dialyte/Celor design.

Enlarging
Since the aberrations remain constant over a wide range of object distances, and is favourable for fairly wide apertures, this design proved useful for enlarging lenses.

Bede BD-8. 

The Bede BD-8 was an aerobatics aircraft developed in the United States in the mid-1970s.  It was a low-wing, single-seat monoplane of conventional configuration, albeit very short-coupled, and of all-metal construction.  The single prototype was under construction by Jim Bede when his company, Bede Aircraft, faced bankruptcy in 1977.  The incomplete BD-8 was purchased by Mike Huffman, who completed its construction in 1980. It first flew on May 14, 1980.

The Beets Special was a single-seat recreational aircraft built in the United States in the mid-1970s with the intention of marketing it for homebuilding. It was a parasol-wing monoplane of conventional configuration with fixed tailwheel undercarriage.

The single prototype (registration N711GB) was constructed by Glen Beets who was working as a welder for Lou Stolp at the time.  He based his general design on the Stolp Starduster biplane, which was being offered to the homebuilt aircraft market at the time.  Plans for the Beets Special were marketed by Stolp's company at one time.

MPM (automobile). The M.P.M. was an automobile built in Mount Pleasant, Michigan by the Mount Pleasant Motor Company from 1914 to 1915.

History 
The M.P.M. was a medium-sized conventional car equipped with either a four-cylinder or eight-cylinder engine.  After building 10 cars, financing could not be raised to continue production.

The company had plans to move its manufacturing plant to either Alma or Saginaw at the end of 1915, but the company closed before that happened.

Plaxton Expressliner. The name Plaxton Expressliner or National Expressliner can refer to one of three designs of coach built by Plaxton for National Express use:

 The original Expressliner was a Plaxton Paramount III 3500 to National Express specification, easily recognisable from the standard Paramount by having a windowless rear end incorporating the National Express logo.
 The Expressliner II was a continuation of the same concept using the Plaxton Premiere 350 body, which replaced the Paramount.
 The Paragon Expressliner is based on the Paragon and replaced the Expressliner II in 2000.

Intel P35. The P35 Express (codenamed Bearlake) is a mainstream desktop computer chipset from Intel released in June 2007, although motherboards featuring the chipset were available a month earlier.
The P35 Express chipset supports Intel's LGA 775 socket and Core 2 Duo and Quad processors, and is also known to support 45 nm Wolfdale/Yorkfield dual and quad core CPUs. Theoretically, Intel also dropped support for Intel's Pentium 4 and Pentium D processors with this chipset although late Pentium 4 processors, including both the 32-bit-only (5x0) and the 32-bit/64-bit (5x1), and a few others, were fully supported.

It is notable for providing the first commodity support of DDR3 SDRAM. It also supports DDR2 SDRAM; the choice is made by the motherboard manufacturer, and some manufacturers supported both DDR3 and DDR2 on the same motherboard, but only one memory type at a time, often 4× DDR2 or 2× DDR3, as in the Gigabyte GA-EP35C-DS3L/R; but DDR3-only models, such as the Gigabyte GA-EP35T-DS3L/R and the DDR2-only models, such as the Gigabyte GA-EP35-DS3L/R were also made, concurrently. Another notable point is that it does not provide Parallel ATA support; most 2007 motherboards added PATA support via a JMicron JMB361 or JMB363 chip.
