MGWR Class B. The Midland Great Western Railway (MGWR) B Class 0-6-0 was a class of 4 locomotives built at North British Locomotive Company in 1904.  In 1925 they were allocated Great Southern Railways (GSR) Class 646 / Inchicore Class J2.

The MGWR Class B was an attempt at a more powerful 0-6-0 locomotive than the existing Class L.  Like the Class A 4-4-0 which they shared some components they were weight restricted to the Dublin-Galway on the MGWR.  They were rebuilt 1916/17 with superheating.  On scrapping some of their tenders were givin to Class A locomotives.

Korean vertical launching system. The Korean vertical launching system (K-VLS or KVLS) is a hot-launch vertical launching system developed by South Korea to be deployed by the Republic of Korea Navy. It is used in the Sejong the Great-class destroyer, KSS-III submarine, and is scheduled to be added to the Daegu-class frigate. The K-VLS can deploy the Cheongung air defense missile (KM-SAM), Haegung air defense missile (K-SAAM), K745A1 Red Shark anti-submarine missile, Haeseong-II, Hyunmoo-3 land-attack cruise missiles and even SLBMs.

Three systems may be referred to as K-VLS.
 The "K-VLS" is comparable in size and role to the strike-length Mk 41 VLS. It comes in 8-cell modules sized at 3.165 m × 2.076 m × 7.7 m.
 The "K-VLS Compact" is specialized for the K-SAAM surface-to-air missile. It comes in modules of 4 cells, sized at 2.9 m × 2.6 m × 4.9 m (length-width-height). Its role can be compared to the Mk 48/56 VLS for RIM-162 ESSM.
 Dosan Ahn Changho-class submarines use a K-VLS that has a module size different from either version. Presumably this is a distinct variant comparable in role to the US Mk 45.

A newer version called KVLS-II was unveiled in 2021. It comes in modules of 4 cells, sized at 3.0 m × 2.4 m × 9.8 m (L-W-H). An upsized system with increased exhaust handling capacity, its role is comparable to the US Mk 57 VLS.

Daegu-class frigate. The Daegu-class frigate (Hangul: 대구급 호위함, Hanja: 大邱級護衛艦) is a class of guided missile frigates of the Republic of Korea Navy (ROKN). The Daegu class is based on the preceding , and has otherwise been referred to as the Incheon class batch II, or FFG-II. Eight Daegu-class ships have been commissioned, with the final goal of 20–22 frigates, of all types, in the ROKN. The Daegu-class frigates were built by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries.

Features

The Daegu class is an improved variant of the . Modifications to the Incheon class include  a TB-250K towed array sonar system and a 16-cell Korean Vertical Launching System (K-VLS), that is able to deploy the K-SAAM, K745A1 Red Shark anti-submarine missile, and SSM-700K Haeseong tactical land attack cruise missiles.

The hull design is generally based on the Incheon class. As a part of weapon system modifications, the superstructure has been significantly changed. The hangar and a helicopter deck on the stern has been enlarged to support the operation of a 10-ton helicopter.

The Daegu class is the first Korean warship equipped with a combined diesel-electric or gas (CODLOG) propulsion system. The propulsion system of the ROKN ships have a gas turbine direct drive, and four high speed diesel generators driving two Leonardo DRS permanent magnet electric motors. The Rolls Royce MT30 turbine engine replaces the twin gas turbine layout of the Incheon-class frigates.

The Daegu class provides improved anti-submarine warfare (ASW) capability than the predecessor Incheon class. An improved ASW capability is provided by the Hanwha Systems SQS-250K towed array sonar and SQS-240K hull-mounted sonar.

Les Besser. Les Besser (born 1936) is an American electronics engineer, an expert in microwave technology. He is the founder (1973) of Compact Software, the first commercially successful microwave computer-aided design (CAD) company, which  commercialize his program COMPACT (Computerized Optimization of Microwave Passive and Active CircuiTs).

Les Besser was born and raised in Hungary (interbellum and World War II Hungary and the Hungarian People's Republic). In 1956, he escaped to the West, and he became a Canadian citizen in 1971. Later, he moved to the United States, graduated from the University of Colorado, and, in 2000, he became a naturalized U.S. citizen.

Besser began working on simulators during his employment at Hewlett-Packard (1966–1969), using the BASIC computer language and time-sharing computers. After leaving HP, he joined the newly formed microwave division of Fairchild Semiconductor, where he authored his first-generation program, SPEEDY, Besser later converted another program, originally written for his graduate thesis work, to run on a commercial time-share system and launched a part-time business, Compact Engineering (later renamed Compact Software). Besser submitted the description of COMPACT to IEEE Transactions on Circuit Theory in 1972, but it was initially rejected, and was not accepted until after the addition of a large amount of mathematics into it. Besser was associated with development of COMPACT until 1983. In 1985, Besser founded Besser Associates, a company that offers education in microwave technology. He also co-authored several textbooks on the subject. In 2004, he retired and sold the company but continued occasionally teaching courses.

Besser has received numerous international recognitions and awards and was listed in the Marquis "Who Is Who in American Colleges and Universities" in 1966 and "Who Is Who in the World" in 1995.

In 2013, The Hewlett-Packard Memory Project published Les Besser's two-volume memoir, "Hurdling to Freedom: A Hungarian's Escape to America," downloadable without charge from the Project's website.
 
From 1988 to 1990 he was the editorial director of Microwave Systems News (MSN) magazine.

He has been a member of the American Hungarian Federation. In 2018, Besser and his wife Susan were living in Carlsbad, California.

Rivets (board game). Rivets is a post-apocalyptic board wargame published by Metagaming Concepts in 1977.

Description
Rivets is a two-player game featuring combat between robotic tanks, taking place after the human race has been annihilated. The game posits that gangs of semi-intelligent robots roam the landscape, fighting with other gangs over sources of spare parts.

Components
The microgame, packaged in a ziplock bag, comes with
17-page rulebook with cover art
8" x 14" two-color map
188 thin cardstock counters

Setup
The two players agree on a point value for their gangs, and secretly "buy" various robot models up to the point limit.

Gameplay
The players program their robots' movements in secret and reveal their moves simultaneously. The winner is the player whose robot gang survives the combat.

Publication history
Metagaming Concepts pioneered the concept of the minimalist ziplock-packaged microgame in 1974. Three years later, the MicroGame line published Rivets, a microgame designed by Robert Taylor with artwork by Brian Wilson.

Reception
In the inaugural edition of Ares Magazine (March 1980), David Ritchie was not impressed by this game, finding it boring and predictable, saying, "If it all sounds slightly silly ... it is. This one is simple, and should be played by players with the average intelligence of an electric can opener. An average game lasts three-quarters of an hour." He concluded by giving Rivets a very poor rating of 3 out of 9.

In the October 1980 issue of Fantastic, game designer Greg Costikyan called the game "one of my personal favorites ...  It was a cute game."

In Issue 36 of Phoenix (March–April 1982), S.N. Goodwin found too many acronyms in the rules, using as an example, "If a BCPC attacks a TB (PTA RBs) and rolls an AR on the CRT, do you treat it as NE?" Goodwin also found the thin counters and the small map "the worst features of the game [...] hopelessly small for sustained e.g. Club, play." However, he thought the actual game was challenging and enjoyable, calling it "quite exceptional value in terms of its sustained interest value." He concluded "Even if you don't like [science fiction], for £2 why not give this one a try?"

In Issue 27 of Simulacrum, Brian Train noted, "There is enough variation in the types of robots, combined with the ability to re-program them during the game, to keep trying out new strategies and force mixes for some time."

In Issue 35 of Warning Order, Matt Irsik commented, "Definitely one of the more quirkier sci-fi games you'll ever see.[...] A lot of fun."

Car elevator. A car elevator or vehicle elevator is an elevator designed for the vertical transportation of vehicles inside buildings, so increasing the number of vehicles that can be parked in parking lots and parking garages. Where real estate is costly, these car parking systems can reduce overall costs by using less land to park the same number of cars. 

Vehicle lifts, which lift a car at its center of gravity, are used in garages and repair shops and are designed to allow access to a car's undercarriage for repair.

Examples
American politician and former presidential candidate Mitt Romney included a car elevator in his 2008 proposal for rebuilding his beach house in La Jolla, San Diego. The elevator is intended to transport cars between floors in a planned split-level, four-vehicle garage. Romney received final approval for the project in October 2013, after an appeal against San Diego's approval of the project was dismissed.

The Porsche Design Tower, a high-rise residential building with 132 units in Sunny Isles Beach, Florida, near Miami, contains three car elevators. The elevators, named "Dezervators" after building developer Gil Dezer, transport cars up to parking spaces directly connected to each apartment unit. The elevators are in circular glass structures and rotate to align with the correct car parking space, allowing residents to exit directly from their cars to their apartments. The building opened in 2017. Another nearby building in Sunny Isles Beach, the Bentley Residences, uses the same technology in a slightly larger building. It will have more automobile capacity with four car elevators and be the tallest building in Sunny Isles Beach. 

The Boring Company, a company owned by entrepreneur Elon Musk, built a prototype car elevator in 2017. In 2018, the company received permission from the Hawthorne, California city council to construct a car elevator designed to connect an above-ground garage to the Boring Test Tunnel, an underground test tunnel. The Boring Company intends to use the test tunnel and elevator for research and development of a proposed underground Hyperloop system designed to solve traffic congestion in Los Angeles.
