Grif H2000. The Grif H2000 is an Italian high-wing, single and two-place family of hang gliders, designed and produced by Grif Italia, of Castel Sant'Elia.

Design and development
The H2000 was designed for beginners and for flight training and has been progressively improved since its introduction in 1995 under the name Hobby. The H2000 is built in four sizes, with the single place versions designated by their approximate wing area in square meters.

The aircraft is made from aluminum tubing, with the wing covered in Dacron sailcloth. Its wing is cable braced from a single kingpost and has a nose angle of 120°. Unlike many training and beginner gliders the H2000 is not a single surface wing, but has about 50% double surface that encloses the crossbar.

The manufacturer provides a long list of options for the glider, including Hall wheels, ergonomic speed bar, rubber covered upright tubes and a Trilam wing leading edge.

Steve Kordek. Steve Francis Kordek (December 26, 1911 – February 19, 2012) was an American businessman of Polish descent who was best known for the design of the pinball machines.

Kordek is credited with designing over 100 pinball machines.  The last game Kordek helped design was 2003's Vacation America. Among the companies that Kordek designed for are Genco, Williams and Bally.

Kordek was credited with many innovations to pinball machines.  He revised the pin game machines of the 1930s by putting two inward-facing flippers at the bottom of the playing field that were controlled by two buttons on the side of the machine. Other innovations still used today are drop targets and multi-ball mode.

Kordek died on February 19, 2012, at age 100.

Kordek can be seen at the age of 81 when the television show Wild Chicago toured the Williams factory in 1993

National Warplane Museum. The National Warplane Museum is a warbird and military history museum currently located on the grounds of the Geneseo Airport in Geneseo, New York. Founded in 1994, the museum restores, flies, and displays vintage military aircraft from the Second World War and Korean War eras.  In 1998, after a split developed in the membership with two thirds of the group wanting to move to a modern airport and grow, the National Warplane Museum moved to the Elmira-Corning Regional Airport near Horseheads, New York.  In 2010, the Horseheads museum reinvented itself as the Wings of Eagles Discovery Center.  In 2013, the National Warplane Museum name was reacquired by the 1941 Historical Aircraft Group which remained in Geneseo.   The museum hosts the annual Geneseo Airshow, billed as the "Greatest Show On Turf."

Communications Capabilities Development Programme. The Communications Capabilities Development Programme (CCDP) is a UK government initiative to extend the government's capabilities for lawful interception and storage of communications data. It would involve the logging of every telephone call, email and text message between every inhabitant of the UK, (but would not record the actual content of these emails)  and is intended to extend beyond the realms of conventional telecommunications media to log communications within social networking platforms such as Twitter and Facebook.

It is an initiative of the Office for Security and Counter-Terrorism at the Home Office, whose Director is Tom Hurd. The office pursued a very similar initiative under the last Labour government, called the Interception Modernisation Programme, which after apparently being cancelled, was revived by the Liberal-Conservative coalition government in their 2010 Strategic Defence and Security Review.

The effort to develop it will be led by a new government organisation, the Communications Capabilities Directorate. In March 2010, it was reported that the Communications Capabilities Directorate had spent over £14m in a single month on set-up costs.

Placzek transient. The Placzek transient is a phenomenon studied in nuclear engineering. The Placzek transient occurs when a population of monoenergetic neutrons of energy E elastically scatter within a homogeneous medium. In each collision the neutrons impart a fraction of their energy to the nuclei in the medium, losing up to a maximum of

where A is the atomic number of the medium. In nuclear engineering, neutrons that have not yet undergone a collision are called the 1st generation, those that have undergone a single collision are the 2nd generation, those that have undergone two collisions are the 3rd generation, and so on. The neutrons from each generation collectively form the total neutron population within the medium.

The Placzek transient is a discontinuity of the neutron flux, and derivatives of the flux, at integer multiples of . The transient results from the fact that after the 1st generation, every neutron can have at minimum an energy of  due to elastic scattering. Those neutrons that have energy less than  can only consist of neutrons in the 2nd, 3rd, or latter generations. This trend repeats itself at each multiple of . Thus, the discontinuity in the flux arises from the fact that at each multiple of  the neutron flux is accumulated from one fewer neutron generation to the left of the discontinuity than to the right.

The Placzek transient can be derived analytically by solving for the neutron flux using a piecewise function solution to a differential equation involving a Heaviside step function in energy intervals of width . The transient can also be observed in some special case Monte Carlo neutron transport simulation codes.

Nuclear magnetic resonance logging. Nuclear magnetic resonance (NMR) logging is a type of well logging that uses the NMR response of a formation to directly determine its porosity and permeability, providing a continuous record along the length of the borehole.

Background
NMR logging exploits the large magnetic moment of hydrogen, which is abundant in rocks in the form of  water.  The NMR signal amplitude is proportional to the quantity of hydrogen nuclei present in a formation and can be calibrated to give a value for porosity that is free from lithology effects.  Uniquely, a petrophysicist can also analyse the rate of decay of the NMR signal amplitude to obtain information on the permeability of the formation - a crucial quantity in hydrocarbon exploration.

Relationship of NMR signal to pore size
The most important mechanism affecting NMR relaxation is grain-surface relaxation.  Molecules in fluids are in constant Brownian motion, diffusing about the pore space and bouncing off the grain surfaces.  Upon interaction with the grain surface, hydrogen protons can transfer some nuclear spin energy to the grain (contributing to T1 relaxation) or irreversibley dephase (contributing to T2 relaxation).  Therefore the speed of relaxation most significantly depends on how often the hydrogen nuclei collide with the grain surface and this is controlled by the surface-to-volume ratio of the pore in which the nuclei are located.  Collisions are less frequent in larger pores, resulting in a slower decay of the NMR signal amplitude and allowing a petrophysicist to understand the distribution of pore sizes.

CNK operating system. Compute Node Kernel (CNK) is the node level operating system for the IBM Blue Gene series of supercomputers.

Operating system
The compute nodes of the IBM Blue Gene family of supercomputers run CNK, a lightweight kernel that runs on each node and supports one application running for one user on that node. To maximize operating efficiency, the design of CNK was kept simple and minimal. It was implemented in about 5,000 lines of C++ code. Physical memory is statically mapped and the CNK neither needs nor provides scheduling or context switching, given that at each point it runs one application for one user. By not allowing virtual memory or multi-tasking, the design of CNK aimed to devote as many cycles as possible to application processing.

CNK delegates file input/output (I/O) to dedicated I/O nodes which run the INK (I/O Node Kernel) operating system, based on a modified Linux kernel.
