Monotube steam generator. A monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a once-through steam generator (OTSG). The first of these was the Herreshoff steam generator of 1873.

Principles
For the sake of efficiency, it is desirable to minimise the steam content of the generator. Heat can then be transferred efficiently into liquid water, rather than into low-density steam. Monotube steam generators may either boil gradually along their length, usually pumped circulation systems, but where this boiling does not disrupt the circulation. Otherwise they can use the Benson supercritical system, where the pressure is sufficient to prevent boiling (within the heated volume) altogether.

Examples

Examples of Monotube steam generators include:
 Industrial steam generators 
 The water-tube boilers of the monotube type used in steam cars, such as:
 AMC
 Clayton Steam Generator
 Doble steam car
 Gardner-Serpollet
 Locomobile Company of America
 White Motor Company, US patent 659,837 of 1900

Flash boilers

A flash boiler is a particular type of low-water-content monotube boiler. Modern use is confined to model steam boats but, historically, flash boilers were used in Gardner-Serpollet steam cars.

Henry Arthur Campbell. Henry Arthur Campbell MIEE (24 June 1873 to 6 June 1953) was a Jamaican electrical engineer and long-serving employee and Chief Engineer of the Jamaican public utility.

Education and career

Henry was tutored privately and at Church of England grammar schools in his early years, before apprenticing as an electrical engineer with the Jamaica Electric Light and Power Co. Ltd. beginning in 1890.

He notably contributed to the establishment and maintenance of an electric tram system in Kingston, Jamaica, and was recognized by the British Admiralty for having "rendered invaluable services" during both World War I and World War II.

He worked for over sixty years with the Jamaica Public Service Co. Ltd., from 1890 until after 1953, though in his latter years in the role of a consultant.

He rose to head several committees and clubs with the company, during his time there, including membership in the Apprenticeship Committee, chairman of the managing committee of the company's employee's thrift club, and vice-chairman of the company's mutual aid society.

He became an associate member of the Institution of Electrical Engineers in 1928, and later a member in 1932.

In-target probe. In-target probe, or ITP is a device used in computer hardware and microprocessor design, to control a target microprocessor or similar ASIC at the register level. It generally allows full control of the target device and allows the computer engineer access to individual processor registers, program counter, and instructions within the device. It allows the processor to be single-stepped or for breakpoints to be set. Unlike an in-circuit emulator (ICE), an In-Target Probe uses the target device to execute, rather than substituting for the target device.

Molve gas project. The Molve gas project () is a natural gas extraction project in northern Croatia operated by INA, the national oil company. The Molve project is headquartered in Đurđevac in the Koprivnica-Križevci County and includes eight gas fields in the Podravina basin: the four main fields are Molve, Kalinovac, Stari Gradac and Gola Duboka, in addition to four smaller ones called Ferdinandovac, Gola, Hampovica-Čepelovac and Pepelana.

Large natural gas deposits were first discovered on the site in 1974, and the project started operating in 1980. The Molve project produces natural gas, natural gas condensate, C2+ mixture (a byproduct consisting of ethane, propane, butane and higher molecular weight hydrocarbons) and oil. In the period between 1980 and 2005 Molve produced a total of 25 billion cubic metres of gas, and 8 million tons of gas condensate. The Molve project is the biggest and most important natural gas deposit in the country as the four main fields' output makes up 70 percent of the total natural gas production in Croatia, and the gas condensate and C2+ mixture outputs account for around 30 percent of the total primary energy production in Croatia.

Evasion (network security). In network security, evasion is bypassing an information security defense in order to deliver an exploit, attack, or other form of malware to a target network or system, without detection. Evasions are typically used to counter network-based intrusion detection and prevention systems (IPS, IDS) but can also be used to by-pass firewalls and defeat malware analysis. A further target of evasions can be to crash a network security defense, rendering it in-effective to subsequent targeted attacks.

Description
Evasions can be particularly nasty because a well-planned and implemented evasion can enable full sessions to be carried forth in packets that evade an IDS. Attacks carried in such sessions will happen right under the nose of the network and service administrators.

The security systems are rendered ineffective against well-designed evasion techniques, in the same way a stealth fighter can attack without detection by radar and other defensive systems.

A good analogy to evasions is a system designed to recognize keywords in speech patterns on a phone system, such as “break into system X”. A simple evasion would be to use a language other than English, but which both parties can still understand, and wishfully a language that as few people as possible can talk.

Evasion attacks
Various advanced and targeted evasion attacks have been known since the mid-1990s:

 A seminal text describing the attacks against IDS systems appeared in 1997.
 One of the first comprehensive description of attacks was reported by Ptacek and Newsham in a technical report in 1998.
 In 1998, also an article in the Phrack Magazine describes ways to by-pass network intrusion detection.

Reports
The 1997 article mostly discusses various shell-scripting and character-based tricks to fool an IDS. The Phrack Magazine article and the technical report from Ptacek et al. discusses TCP/IP protocol exploits, evasions and others. More recent discussions on evasions include the report by Kevin Timm.

Protecting against evasions
The challenge in protecting servers from evasions is to model the end-host operation at the network security device, i.e., the device should be able to know how the target host would interpret the traffic, and if it would be harmful, or not. A key solution in protecting against evasions is traffic normalization at the IDS/IPS device. The other way separation internet access can be implemented based on how endpoint user can be safe accessing the internet segment.

Lately there has been discussions on putting more effort on research in evasion techniques. A presentation at Hack.lu discussed some potentially new evasion techniques and how to apply multiple evasion techniques to by-pass network security devices.

Norman Spratt. Norman Channing Spratt (1885–1944) a native of Durban, Colony of Natal, was an officer of the Royal Flying Corps during the First World War who was involved in aircraft testing at the Royal Aircraft Establishment, Farnborough, United Kingdom. He later served as a group captain in the Royal Air Force. He was awarded the Order of the British Empire in 1925.

On 7 December 1913, Spratt, as factory test pilot, crashed Royal Aircraft Factory B.E.2a, 235, at the Farnborough Aerodrome, pilot surviving.

In 1914, Spratt set a new airspeed record in a Royal Aircraft Factory S.E.4, at 134.5 mph, bringing the speed title to the U.K. for the first time.

On 14 May 1914, Norman Spratt set a British altitude record of 18,900 ft. while flying one of two Royal Aircraft Factory R.E.5 reconnaissance designs, the fifth and sixth machines, which were produced as single-seat 'height machines', with long strut-braced extensions on the upper wing, which gave it a span of 57 ft 2.39in.

On 12 August 1914, the sole Royal Aircraft Factory S.E.4, 628, crashlanded at 1145 hrs. while being flown by Lt. Spratt when one of the wheels collapsed, airframe overturning, sustaining such extensive damage that it was abandoned.

The first dogfight is believed to have taken place on 28 August 1914, when Spratt, flying a Sopwith Tabloid, forced down a German Albatros C.I two-seater. This was an amazing achievement as his Sopwith was not armed.

The prototype Armstrong Whitworth F.K.3 was first test flown by Spratt in 1915.

Spratt served as a Group Captain during World War II, but died from ill-health in 1944.

Borys Aleksandrov (research vessel). RV Borys Aleksandrov is a Ukrainian research vessel which was built in 1984. She was previously crewed by the Belgian Naval Component as RV Belgica and is in active service.

Description
Borys Aleksandrov is  long, with a beam of  and a draught of . Assessed at , , she has a displacement of 1,200 tons. The ship is propelled by a  ABC 6M DZC1000-150 diesel engine, driving a kort nozzle ducted propeller. She has a  bow and stern thruster and a  electric motor.

Borys Aleksandrov has a range of  at . Her maximum speed is . She is fitted with a Kongsberg EM 1002 and EM 3002 sonar and an acoustic doppler current profiler. There are five laboratories on board. Power is provided by two diesel powered generators of  each.

History
Belgica was built by Boelwerf, Temse. She was launched on 6 January 1984 and commissioned on 5 July 1984. Her homeport was Zeebrugge. She was allocated the IMO Number 8222563, MMSI Number 205218000 and pennant number A962. Belgica used the callsign ORGQ. She was named after the RV Belgica, a ship used by Adrien de Gerlache in the Belgian Antarctic Expedition (1897–99).

Belgica was operated by the Management Unit of North Sea Mathematical Models (MUMM) and crewed by the Belgian Naval Component.

In 2013 mechanical problems caused the aging vessel to be taken out of service for four weeks, which prompted the Belgian government to plan her replacement by 2017. This was later postponed to 2020.

In 2021, Belgium gifted the vessel to Ukraine. She was renamed from Belgica to Borys Aleksandrov.

IAI Panther. The Israel Aerospace Industries Panther is a tilt-rotor unmanned aerial vehicle (UAV) produced by Israel Aircraft Industries in Israel.

The Panther employs a tilt-rotor propulsion system patented by IAI and designed for tactical use, allowing runway-free takeoffs and landings on unprepared locations. It features three "ultra-quiet" electric motors, two of which are tilt-rotor and one providing additional lift for hovering, takeoff and landing.
An automatic flight-control system controls the transition between the rotors' various positions.

Weighing roughly  the Panther has an operational radius of over  and can loiter for approximately six hours at an altitude of  . Its payload is IAI's Mini-POP electro-optical/infrared sensor, a stabilised camera with a laser rangefinder, pointer or laser designator.

The Panther is controlled from a two-man control station, one to control the aircraft and oversee tactical missions, and the other to act as the station manager. The two use identical consoles, while takeoff and landings are handled automatically.

A smaller version of the Panther, the Mini-Panther, is also available. Weighing  and capable of loitering for about two hours, it is controlled from a command and control center carried in backpacks by two operators.

The Panther was expected to be operational in 2011. The Panther was unveiled on October 5, 2010, at the Israeli land forces conference at Latrun and will be on display at the Association of the US Army’s (AUSA) 2010 Annual Meeting and Exposition in Washington DC. IAI revealed that the Panther is being evaluated by foreign special forces.

In October 2015, IAI unveiled a Panther version with a hybrid propulsion system called the Front Engine Panther (FE-Panther).  The aircraft integrates an electric and internal combustion engine, increasing weight only to  while increasing endurance by 33 percent with the same  payload; the tilting electric motors are optimal for vertical takeoff, landing, and hovering, while the combustion engine would be employed for cruising.  IAI signed a Memorandum of Understanding (MoU) with South Korean company Hankuk Carbon to offer the FE-Panther to fulfill the country's requirements for a VTOL UAS that can operate independently of runways in Korea's mountainous terrain.

Métral submachine gun. The Métral submachine gun is a submachine gun designed by Swiss army reserves officer Gérard Métral intended for clandestine manufacture and distribution during foreign occupation circumstances.

It is a blowback, select fire, Uzi type design, open bolt submachine gun, with a side folding stock. The design and function of the parts are based on various existing submachine guns (like Suomi M1931 for the trigger mechanism and Ingram MAC-10 for bolt security etc.), along with some of the author's own innovations and solutions, for example, the bolt construction and folding stock.

Although the subtitle of the book detailing its design and constructions calls it "homemade", the design is mainly intended for a more professional, almost mass-production kind of manufacture.

Its designer calls for any constructor to be skilled at metalwork, with access to a shop lathe, drill press and milling machine (the last being optional but very helpful). Métral himself says of the main spring, barrel and magazine construction: "Try doing it yourself only if you have no other choice" and calls them "difficult to build". Some parts need hardening, which is usually beyond the means of an amateur, and several parts are intended to be purchased or having them made to order. However care has been taken to keep the appearance of all the separate parts as inconspicuous as possible.
