Multibook. A Multibook or a TACLANE  Multibook is a single laptop that combines two to three different classified networks  into a single device solution.  Currently, most secure computing standards require the federal government and military personnel to maintain multiple PCs on different networks in an effort to allow users simultaneous access to unclassified and classified information.   A multibook simply through a complex configuration allows separate enclaves and virtual machines through one display.
A Multibook  has no hard drive and uses a cryptographic ignition key to create a virtual hard drive space with a Type 1 COMSEC element found inside the MultiBook’s integrated Suite B security module.

The security module known as a HAIPE protects information stored on the computer, as well as data being sent to and from networks classified Secret and below.   Due to the lack of stored collateral data, multiBooks do not have any burdensome COMSEC handling requirements. There is no Data at Rest (DAR) when equipment is turned off.

Some multibooks are NSA certified to protect information classified Secret and below.  They are approved for Suite B information/processing with data in transit (DIT) encryption protecting information when sent to and from classified networks.

The multibook security benefit for the user is that the device is a CHVP device and is not considered CCI like other devices used in collateral processing.

Cryptographic High Value Product. Cryptographic High Value Product (CHVP) is a designation used within the information security community to identify assets that have high value, and which may be used to encrypt / decrypt secure communications, but which do not retain or store any classified information.  When disconnected from the secure communication network, the CHVP equipment may be handled with a lower level of controls than required for COMSEC equipment.

Nangbeto Dam. The Nangbeto Dam is an embankment dam on the Mono River in the Plateaux Region of Togo. It was constructed between 1984 and 1987 for the purpose of providing hydroelectric power to both Togo and Benin as well as creating fisheries and supplying water for irrigation. The dam's  power station was commissioned in June 1987. The project was financed by the World Bank and African Development Bank at a cost of US$98.22 million.

The objectives of the dam were to satisfy the medium-term requirements of Benin and Togo for power, and to provide a large water reserve, amounting to 1.7 billion cubic metres. It was expected that 1000 to 1500 tonnes of fish would be produced each year and that 43,000 hectares of land would be irrigated. Evaluation of the project six years later showed that the project had been completed on time and on budget to a satisfactory standard. The project was a good example of cooperation between the two countries. The power generation objective was satisfied but the fish development scheme had failed and the irrigation project was proceeding at a slower rate than expected. However, initial results of the cultivation of rice on the irrigated land were encouraging.

The Nangbeto Dam serves part of Togo's needs for electricity and is subject to interruptions in supply when the water level is low, which may happen for periods of several months. As a result, a further dam on the Mono River further downstream at Adjaralla is being constructed, starting in 2016. The fish production scheme involved in this project and other environmental issues are being planned at an earlier stage in its development.

Rehabilitation
In 2017, Communauté Electrique du Bénin, the electric grid operator in Togo and Benin advertised for a company to undertake the rehabilitation of this power station which had not undergone any major overhaul since commercial commissioning in 1987.

Voith Hydro, a German manufacturer and installer of hydromechanical and electricity hardware was selected to rehabilitate and modernize the two 32.5 megawatt turbines. The contractor will work on one generator at a time, in order to maintain output from the turbine that is not under repair/rehabilitation. The work expected to last until the fourth quarter of 2022, cost US$25 million.

John Dixon (engineer). John Dixon (c.1795–1865) was an English railway civil engineer, and was the Stockton and Darlington Railway's Chief Civil Engineer between 1842 and 1865.

History
John Dixon started work as a bank clerk and in 1821, at the age of 26, assisted George and Robert Stephenson to survey the Stockton and Darlington Railway. Dixon became one of the two Resident Engineers when George was later awarded the post of Engineer.  Dixon is listed as an assistant engineer when the company of George Stephenson & Son was formed to survey and build railways at the end of 1824. He assisted George building the Liverpool and Manchester Railway and was at the Rainhill Trials, and wrote a letter, which still exists, describing the event to his brother James. He was an engineer for the Grand Junction Railway, and returned to Darlington become Chief Civil Engineer to the Stockton and Darlington Railway between 1842 and 1865.

John Dixon was the great nephew of Jeremiah Dixon, who with Charles Mason set the Mason–Dixon line that separates Northeastern from Southern United States. He died in Darlington, aged 68, on 10 October 1865.

The John Dixon responsible for transporting Cleopatra's Needle to England was the nephew of this man. He was born on 2 January 1835 and died in Croydon on 28 December 1891.

Hammerhead usv-t. The Hammerhead USV-T (Unmanned Surface Vehicle Target) is a remote-controlled, high-speed seaborne target drone used for naval training. The craft is built and produced by Meggitt Training Systems in cooperation with A. F. Theriault & Son Ltd and approximately 80 other companies that produce innards and accessories of the boats. The Hammerhead USV-T is used for tactical training scenarios at sea.

Production
In 2010 Meggitt achieved a world first by successful demonstrating to the International Naval Community to be able to control 16 of their Hammerheads for a period of 7 hours. During this time many of the useful applications and equipment designed into the Hammerhead were demonstrated. Since 2010 over 190 units have been sold to Canada, United Kingdom, South Africa, United States, and Germany. Meggitt Training Systems has recently been ranked second among Canada’s leading defense companies.

Specifications
The boat's hull measures 17’ in length and weighs 900 kg. It is equipped with a 3.0L four cylinder engine, capable of propelling it up to 40 knots at sea. The fuel capacity is 189 liters and the boat has an endurance of up to 24 hours at speeds below 20 knots. The Hammerhead can be equipped with smoke, flags, strobe lights, naval navigational lights, flares, and forward looking IR signatures, radar and forward looking video. The equipment is controlled by a UTCS (Universal Target Control System) at a single data half-duplex frequency, allowing them to communicate with up to 16 vehicles concurrently. One person can be capable guiding and controlling 4 Hammerhead boats simultaneously, and the craft can also be pre-programmed.

Current Use
They are being built and designed to replicate the fast inshore attack crafts typically traveling in swarms that are being utilized in some highly unstable regions of the world. They are cost effective as one does not need to man them and they also do not need many physical attributes boats of its caliber would need to be equipped with in order to function similarly. This specific model is used to test the defenses of a ship or be a target / target tow vehicle.
