Meitetsu 1700 series. The  was an electric multiple unit (EMU) train type operated by the private railway operator Nagoya Railroad (Meitetsu) in Japan from December 2008 until 2021.

Formation
The fleet consisted of four 6-car sets, formed as follows.

Cars 1, 4, and 6 each had a single-arm pantograph.

Interior

History
The six-car trainsets were formed in 2008 by combining two cars from former 1600 series limited express EMUs with four newly built 2300 series commuter cars. The trains entered service from the start of the revised timetable on 27 December 2008.

The fleet was reliveried from August 2015, starting with set 1701.

Withdrawal 

Withdrawals of the 1700 series commenced in 2019. The four sets of 2300 series cars were used to form four 2200 series six-car sets. These sets, numbered 2231 to 2234, use two newly built limited express cars and four 2300 series cars originally used with the 1700 series sets. The first of these sets to be formed, 2234, entered service in February 2020, using the 2300 series cars from 1700 series set 1704.

All 1700 series limited express cars were scrapped by February 2021.

PIK-3. 

The PIK-3 (Polyteknikkojen Ilmailukerho – Finnish institute of technology students flying club) was a sailplane produced in Finland in the 1950s and 60s. It was designed to be a cheap and easy-to-build aircraft to equip the country's gliding clubs as their standard single-seat machine. It was a conventional design for its day, with a high wing and conventional empennage. Construction was of wood throughout, skinned in plywood.

Design work commenced in 1942, but the prototype did not fly until 1950. Antti Koskinen refined the design for production as the PIK-3A and then further modified the design by replacing the flaps with air brakes, which was designated the PIK-3B.

By the end of the 1950s, a third modification of the original design was carried out by Olavi Roininen as the PIK-3C. This had completely new wings of 15 m (49 ft 3 in) to allow it to compete in the Standard Class. The prototype flew on 20 May 1958, and the design was then modified for production by Suomen Ilmailuliitto.

Variants
 PIK-3 – first prototype with wingspan of 13 m (47 ft 8 in)
 PIK-3A Kanttikolmonen – initial production version of PIK-3
 PIK-3B – PIK-3A with air brakes in place of flaps
 PIK-3C Kajava – PIK-3B with new wings of 15 m (49 ft 3 in) span

Crossed molecular beam. In analytical chemistry, crossed molecular beam experiments involve two beams of atoms or molecules which are collided together to study the dynamics of the chemical reaction, and can detect individual reactive collisions.

Technique 
In a crossed molecular beam apparatus, two collimated beams of gas-phase atoms or molecules, each dilute enough to ignore collisions within each beam, intersect in a vacuum chamber.  The direction and velocity of the resulting product molecules are then measured, and are frequently coupled with mass spectrometric data.  These data yield information about the partitioning of energy among translational, rotational, and vibrational modes of the product molecules.

History 
The crossed molecular beam technique was developed by Dudley Herschbach and Yuan T. Lee, for which they were awarded the 1986 Nobel Prize in Chemistry.  While the technique was demonstrated in 1953 by Taylor and Datz of Oak Ridge National Laboratory, Herschbach and Lee refined the apparatus and began probing gas-phase reactions in unprecedented detail.

Early crossed beam experiments investigated alkali metals such as potassium, rubidium, and cesium.  When the scattered alkali metal atoms collided with a hot metal filament, they ionized, creating a small electric current.  Because this detection method is nearly perfectly efficient, the technique was quite sensitive.  Unfortunately, this simple detection system only detects alkali metals.  New techniques for detection were needed to analyze main group elements.

Detecting scattered particles through a metal filament gave a good indication of angular distribution but has no sensitivity to kinetic energy.  In order to gain insight into the kinetic energy distribution, early crossed molecular beam apparatuses used a pair of slotted disks placed between the collision center and the detector.  By controlling the rotation speed of the disks, only particles with a certain known velocity could pass through and be detected.  With information about the velocity, angular distribution, and identity of the scattered species, useful information about the dynamics of the system can be derived.

Later improvements included the use of quadrupole mass filters to select only the products of interest, as well as time-of-flight mass spectrometers to allow easy measurement of kinetic energy.  These improvements also allowed the detection of a vast array of compounds, marking the advent of the "universal" crossed molecular beam apparatus.

The inclusion of supersonic nozzles to collimate the gases expanded the variety and scope of experiments, and the use of lasers to excite the beams (either before impact or at the point of reaction) further broadened the applicability of this technique.

Multiple frames interface. A multiple frames interface (MFI) is a type of user interface which displays information in a set of frames or panels that can be scrolled vertically on a screen. It is an integrated interface designed to bring together virtually all the services of an internet portal or an operating system onto a single screen.

History
Paned windows were introduced in file browsers in the 1990s in order to divide the window into sections for a more intuitive approach. 
Netscape 2.0 introduced the elements used for html frames in the 1990s (see Netscape Navigator). At that time, Netscape proposed frames to the W3C for inclusion in the HTML 3.0 standard. IGoogle with its gadgets is an early type of MFI.

Description
An MFI consists of a set of panels that can be maximized, minimized, restored, or moved, being tiled on a scrollable "page" on the screen. As of January 2009, only HTML-based MFIs are functional, and no "desktop" versions are available. The HTML-based MFI is an alternative to the web desktop, allowing simultaneous use of multiple rich web applications.

Advantages
The MFIs have several advantages over desktop environments:
From a visual standpoint, the work with frames is more fluent.
Frames do not overlap on the screen.
The number of frames on the screen is limited to a number that can be handled by the user.
Several frames are permanently on screen.

Shortcomings
Scrolling the set of frames can be difficult.
Many panels open permanently use more memory.

Vanadium(III) iodide. Vanadium(III) iodide is the inorganic compound with the formula VI3.  This paramagnetic solid is generated by the reaction of vanadium powder with iodine at around 500 °C.  The black hygroscopic crystals dissolve in water to give green solutions, characteristic of V(III) ions.

The purification of vanadium metal by the chemical transport reaction involving the reversible formation of vanadium(III) iodides in the presence of iodine and its subsequent decomposition to yield pure metal:
 2 V  +  3 I2   ⇌   2 VI3
VI3 crystallizes in the motif adopted by bismuth(III) iodide: the iodides are hexagonal-closest packed and the vanadium centers occupy one third of the octahedral holes.

When solid samples are heated, the gas contains VI4, which is probably the volatile vanadium component in the vapor transport method.  Thermal decomposition of the triiodide leaves a residue of vanadium(II) iodide:
 2 VI3   →   VI2  +  VI4  ΔH = ; ΔS =  mol−1 K−1.

William Clinger (computer scientist). William D. Clinger is an associate professor in the Khoury College of Computer Sciences at Northeastern University. He is known for his work on higher-order and functional programming languages, and for extensive contributions in helping create and implement international technical standards for the programming language Scheme via the Institute of Electrical and Electronics Engineers (IEEE) and American National Standards Institute (ANSI). Clinger was an editor of the second through fifth Revised Reports on Scheme (R2RS – R5RS), and an invited speaker on Scheme at the Lisp50 conference celebrating the 50th birthday of the language Lisp. He has been on the faculty at Northeastern University since 1994.

Research
Clinger obtained his PhD from the Massachusetts Institute of Technology (MIT) under the supervision of Carl Hewitt. His doctoral research revolved around defining a denotational semantics for the actor model of concurrent computing, which is the same model of computing that originally motivated development of Scheme.

In addition to editing the R2RS – R5RS Scheme standards, Clinger's contributions to Scheme have included the development of compilers for two implementations of the language: MacScheme, and Larceny. He also invented efficient algorithms for hygienic macro expansion, accurate decimal-to-binary conversions, and bounded-latency generational garbage collection.

HIPO model. HIPO model (hierarchical input process output model) is a systems analysis design aid and documentation technique from the 1970s, used for representing the modules of a system as a hierarchy and for documenting each module.

History
It was used to develop requirements, construct the design, and support implementation of an expert system to demonstrate automated rendezvous. Verification was then conducted systematically because of the method of design and implementation.

The overall design of the system is documented using HIPO charts or structure charts. The structure chart is similar in appearance to an organizational chart, but has been modified to show additional detail. Structure charts can be used to display several types of information, but are used most commonly to diagram either data structures or code structures.

USS John Warner. USS John Warner (SSN-785) is a nuclear powered  attack submarine of the United States Navy. She is the first in the class to be named after a person; the first 11 Virginia-class subs were named after states. John Warner was originally to be built by the Electric Boat division of General Dynamics in Groton, Connecticut, but the contract was later transferred to Huntington Ingalls Industries Newport News Shipbuilding. She is the second of the Block III subs, which have a revised bow and some technology from  cruise missile submarines. The vessel supports 40 weapons, special operations forces, unmanned undersea vehicles, and the Advanced SEAL Delivery System (ASDS).

The name was announced on 8 January 2009, five days after John Warner, a Republican from Virginia, retired after serving 30 years as a United States senator, making John Warner the 13th U.S. Navy vessel to be named for a living person in the last hundred years.

Construction began on 29 April 2009 with the keel laying ceremony being held on 16 March 2013. Because of the modular construction sequence, the submarine was reportedly already about 59% complete before the official keel laying. The submarine was christened on 6 September 2014. John Warner was commissioned on 1 August 2015 with Commander Dan Caldwell in command.

On 14 April 2018, while on her first deployment, USS John Warner took part in targeted strikes against Syrian military facilities. She fired six Tomahawk cruise missiles, in what was believed to be the first combat use of her class of submarines.
