Carles Buïgas. Carles Buïgas i Sans (18 January 1898 in Barcelona – 27 August 1979 in Cerdanyola del Vallès) was a Catalan architect, engineer, inventor and author.

Biography 

Buïgas was born into an educated family in Barcelona, the son of the architect Gaietà Buïgas. When he was seven, his family moved to Montevideo (Uruguay) but returned to Barcelona in 1910. In 1916, he entered the School of Industrial Engineers of Barcelona; he did not graduate, but he started to work as an assistant for the Exhibition of Electrical Industries of Barcelona. Later he continued to study at the École de Civil Génie in Paris.

In 1922 Buïgas designed his first project with illuminated water fountains for the Royal Palace of Pedralbes. Eugenio d'Ors described his work as a new style of art, the art of agualuz. His most famous work is the Magic Fountain of Montjuic, created for the International Exposition in Barcelona in 1929.

During the Spanish Civil War he settled in Paris, where he resided until 1942. During these years he gained an international reputation and he obtained commissions for projects for international expositions in Paris (1937), Liege (1939), Lisbon (1940), Rome (1953), and the Expo 58 at Brussels. In 1955, he designed the Teatro del Aqua y Luz for the international fair in Santo Domingo. As an inventor he designed a torpedo bomber seaplane in 1914, a device to recover sea sand for construction (1922), a one-person midget submarine (1932), a remote-controlled torpedo guided by ultrasound (1931–1933) and other devices.

Besides his architectural works, Buïgas wrote for magazines and published a number of books. He spent the last years of his life in Cerdanyola del Vallès, where he died and is buried.

BCT Network. The BCT (Brigade Combat Team) network is a layered system of interconnected computers and software, radios, and sensors within the Brigade Combat Team (BCT) designed to increase survivability and strategy on a battlefield where units can communicate internally instead of through a central command. The BCT Network allows for a more efficient use of communication and a possibility to plug combined-arms warfare into the network for better communication.

Deployment 
The BCT network is essential to enable Unified Battle Command and will be delivered to the Army's Brigade Combat Teams in increasing capability increments. The first increment is currently finishing SDD developmental and operational testing and will be delivered to Infantry Brigade Combat Teams in the form of Network Integration Kits (B-kits) with E-IBCT. The first testing of the BCT network occurred in the Joint Multinational Readiness Center (JMRC), Germany, September 2020.

The soldier at every echelon, from Brigade to Squad, will be connected to the proper sensor data and communication relays to ensure proper battle-space situational awareness.

The Network Integration Kit 
The Network Integration Kit (NIK) is a suite of equipment capable of being installed on many vehicles including HMMWV's and MRAPs. It provides the Network connectivity and battle command software to integrate and fuse sensor data into the common operational picture (COP) displayed on the Force XXI Battle Command Battalion/Brigade and Below (FBCB2). The Network Integration Kit consists of an integrated computer system (ICS) that hosts the Battle Command software and the Systems of Systems Common Operating Environment (SOSCOE) software, along with the JTRS GMR radio to provide the interface to the sensors and unmanned systems, as well as voice and data communications with other vehicles and soldiers. Another benefit of this system allows vehicles with destroyed antennae to communicate through other vehicles' antennae.

Soldiers will be able to communicate with the Battalion Tactical Operation Center (TOC), by sending reports on enemy sighting, activity and location utilizing the NIK via the Network allowing for split-time tactical decisions instead of waiting for one commander to approve or deny decisions.

Filigree concrete. The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place technologies.

Description

The process begins by manufacturing thin precast concrete panels, typically 2.25" thick, with the deck's bottom reinforcement included. The panels are then shipped to a jobsite and erected on temporary shoring. Subsequently, the deck's top reinforcing steel is placed on top of the precast panels at the site, and concrete is poured over the entire assembly to achieve the final thickness of the deck.

This process effectively accelerates the construction of structures by eliminating the need for costly and time-consuming field forming, and the placing of bottom reinforcement. Polystyrene blocks are often incorporated into the panels during their manufacture in order to create voids,  reducing both the quantity and cost of concrete added in the field, and the overall weight of the structure, which further reduces the costs of columns and foundations.

The soffits of the panels have a smooth uniform finish as a result of casting them in polished steel molds. This reduces the labor cost and time typically required to grind and patch the soffits of cast-in-place concrete decks to achieve an acceptable aesthetic finish.

The method of deck construction can be applied anywhere conventionally poured-in-place concrete is specified, such as flat plate, beam and slab, and wall-bearing structures.

Rubblization. Rubblization is a construction and engineering technique that involves saving time and transportation costs by reducing existing concrete into rubble at its current location rather than hauling it to another location. Rubblization has two primary applications: creating a base for new roadways and decommissioning nuclear power plants.

Road construction
In road construction, a worn-out Portland cement concrete can be rubblized and then overlaid with a new surface, usually asphalt concrete. Specialized equipment breaks up the old roadway into small pieces to make a base for new pavement. This saves the expense of transporting the old pavement to a disposal site, and purchasing/transporting new base materials for the replacement paving. The result is a smoother pavement surface than would be obtained if a layer of asphalt were to be applied to the unbroken concrete surface. The technique has been used on roads since the late 1990s, and is also being used for concrete airport runways.

The rubblizing process provides many benefits versus other methods of road rehabilitation, such as crack and seat or removal and replacement of a concrete surface including: rubblizing a concrete surface is 52% less expensive than remove and replacing concrete; rubblizing reduces road reconstruction time, from days of lane closures to hours, providing large savings to contractors and reduced impact on travelling public; and rubblization is an environmentally friendly "green" process.,

Nuclear power plant decommissioning
Rubblization is used in decommissioning of nuclear power plants. As with other decommissioning techniques, all equipment from buildings is removed and the surfaces are decontaminated. The difference with rubblization is that above-grade structures, including the concrete containment building, are demolished into rubble and buried in the structure's foundation below ground. The site surface is then covered, regraded, and landscaped for unrestricted use.  This saves the expense of removing and transporting the building pieces to a different site.

Headless computer. A headless computer is a computer system or device that has been configured to operate without a monitor (the missing "head"), keyboard, and mouse. A headless system is typically controlled over a network connection, although some headless system devices require a serial connection to be made over RS-232 for administration of the device. Headless operation of a server is typically employed to reduce operating costs.

PC BIOS limitations 
During bootup, some (especially older) PC BIOS versions will wait indefinitely for a user to press a key before proceeding.  If some basic device, such as a video card or keyboard, are not installed or connected, this could effectively halt an unattended system.

On more modern systems, the BIOS factory setting will typically be configured to behave this way as well, but this setting can be changed with a BIOS setup utility to proceed without user intervention.

Even in cases where a system has been set up to be managed remotely, a local keyboard and video card may still be needed from time to time; for example, to diagnose boot problems that occur before a remote access application is initialized.

Hardware remote control 
Some servers provide for remote control with an internal network card and hardware that mirrors the console screen.  For example, HP offers a system called Integrated Lights-Out (iLO) that provides this function. Remote access to the system is gained using a secure web connection to an IP address assigned to the iLO adapter, and allows for monitoring of the system during start-up, before the operating system is loaded.

Another hardware solution is to use a KVM-over-IP switch. Such a switch is a traditional Keyboard-Video-Mouse device with the added ability to provide remote control sessions over IP.  Connection to the KVM device is gained using a web browser, which allows for remote monitoring of the connected system console port.

Software remote control 

Administration of a headless system typically takes place with a text-based interface such as a command line in Unix or in Linux. These interfaces, often called "virtual terminals" or "terminal emulators", attempt to simulate the behavior of "real" interface terminals like the Digital Equipment Corporation's VT100, but over networks, usually using protocols such as Secure Shell.

One can also use systems such as X Window System and VNC combined with virtual display drivers - this setup allows remote connections to headless machines through ordinary graphical user interfaces, often running over network protocols like TCP/IP.

Heerema Marine Contractors. Heerema Marine Contractors (HMC) is a contractor headquartered in the Netherlands most notable for operation of three of the largest crane vessels in the offshore industry.

History
Heerema Marine Contractors was formed in 1948 by Pieter Schelte Heerema as a small construction company providing oilfield platforms in Venezuela.

In the 1960s the company focused on the North Sea offshore developments. The company developed crane vessels to lift large offshore platforms and modules. The ship shaped crane vessel Challenger was equipped to lift 800 t.

The need for large stable crane vessels to operate in the North Sea environment lead the company to develop the first large semi-submersible crane vessels. In 1978, HMC commissioned Mitsui to construct the two sister semi-submersible crane vessels,  and SSCV Hermod. These vessels could lift 5,400 tonnes with the twin cranes, and were later upgraded to 8,200 tonnes.

In 1988 HMC formed a joint venture with McDermott called HeereMac.

The  was added to the HeereMac fleet, and upon the split of the companies in December 1997, Heerema took ownership of the Thialf, the largest deep water construction vessel and is capable of a tandem lift of 14,200 t (15,600 short tons)

The  was affected by a flooding incident in 2006 and was put out of service for a few months.

Since 2022 the company is led by CEO Philippe Barril.

Vessels
Heerema presently owns and operates the following crane vessels:

Bylgia tug

Plus a number of barges.

Charles Harrison (RAF officer). Lieutenant Charles Philip Harrison   (born 27 July 1888) was a British World War I flying ace credited with five aerial victories.

Military service
Harrison was commissioned as second lieutenant in the Corps of Royal Engineers on 19 November 1915. He served in France and German West Africa, and was promoted to lieutenant on 4 October 1916.

He was seconded to the Royal Flying Corps, and on 17 May 1918 was appointed an observer officer with the rank of second lieutenant, though with the honorary rank of lieutenant. He was posted to No. 98 Squadron, flying in the DH.9. Harrison gained his first victory on 21 April 1918 with Lieutenant A. M. Phillips as pilot, by driving down 'out of control' a Fokker Dr.I over Bailleul. His second came on 8 May, with Lieutenant N. C. MacDonald, when he set on fire an Albatros D.V over Menen–Wervicq. Flying with Lieutenant Frederick Wilton, he accounted for two more Fokker Dr.I's on 16 July, and a Pfalz D.III on 18 July, for a total of five.

Harrison was awarded the Military Cross, which was gazetted on 13 September 1918. His citation read:
Temporary Lieutenant Charles Philip Harrison, Royal Engineers, attached Royal Air Force.
For conspicuous gallantry and devotion to duty. This officer was acting as observer when his pilot was severely wounded. He opened fire and shot down the enemy aeroplane, which fell in flames. He then took control of his own machine, which was very badly damaged, his pilot being "hors de combat," and notwithstanding complete inexperience in piloting a machine he managed to bring it safely back to an aerodrome. His skill and courage undoubtedly saved his pilot's life, and prevented the machine from falling into the hands of the enemy.

In late November 1918 he was awarded the Croix de Chevalier of the Legion d'honneur by the French government.
 
Harrison finally left the RAF, being transferred to the unemployed list on 14 June 1919.

MEX file. A MEX file is a type of computer file that provides an interface between MATLAB or Octave and functions written in C, C++ or Fortran. It stands for "MATLAB executable".

When compiled, MEX files are dynamically loaded and allow external functions to be invoked from within MATLAB or Octave as if they were built-in functions.

To support the development of MEX files, both MATLAB and Octave offer external interface functions that facilitate the transfer of data between MEX files and the workspace. In addition to MEX files, Octave has its  format using its native API, with better performance.

Jamaica Society of Energy Engineers. The Jamaica Society of Energy Engineers (JSEE) is a newly formed public non-profit organization with a mandate to promote the conscientious utilization of energy resources in Jamaica. The JSEE formation was initially spurred by the need for a professional entity to provide and oversee local training and certification of Energy Auditors and Managers.
The JSEE is now a chapter of the Association of Energy Engineers (AEE), which is the world-wide certifying body for all energy engineers.

Formation
The formation of the society was spearheaded by the Computing and Engineering Entrepreneurial Centre, at the University of Technology (UTech) and was officially launched at the Technology Innovation Centre, UTech on 27 February 2009.

The society's objectives are to promote energy matters in organizations, corporate with industries and organizations to provide energy solutions, certify energy professionals and provide career guidance for students at the secondary and tertiary levels.

Background
As part of the Government of Jamaica’s (GOJ) expressed desire to promote the implementation of energy efficiency and conservation practices, the GOJ through the Development Bank of Jamaica (DBJ) made available J$1 Billion to be lent to Small and Medium Size Enterprises (SME’s).  The Project named the “DBJ-PetroCaribe Energy Line of Credit for SME” will be distributed by Approved Financial Institutions (AFIs) (Commercial Banks, Credit Unions and P.C. Banks) to SME members after completing an Energy Audit done by an approved Auditor from the Petroleum Corporation of Jamaica.

The University of Technology, Jamaica was invited to be a partner in the project to establish the Jamaica Society of Energy Engineers and to train persons as Certified Energy Managers  expected to do the audits on the SME. The other members of the partnership are Development Bank of Jamaica (DBJ), Jamaica Trade and Invest (JTI), and Petroleum Corporation of Jamaica (PCJ).

Karl Andreas Hofmann. Karl Andreas Hofmann (2 April 1870 – 15 October 1940) was a German inorganic chemist. He is best known for his discovery of a family of clathrates which consist of a 2-D metal cyanide sheet, with every second metal also bound axially to two other ligands. These materials have been named 'Hofmann clathrates' in his honour.

Hordern-Richmond Autoplane. The Hordern-Richmond Autoplane was a 1930s British twin engined two seat cabin touring monoplane designed by Edmund Hordern, and constructed by Heston Aircraft Company Ltd.

Development
The Autoplane was designed by Edmund G. Hordern in collaboration with Frederick Duke of Richmond and Gordon, and built in 1936 by Heston Aircraft Company at Heston Aerodrome near London. The aircraft was planned to be manufactured and marketed by Hordern-Richmond Aircraft Ltd that was formed by the co-designers in April 1937.

Construction was primarily wooden, with plywood skinned frames. The wings were cantilever, and could be folded outboard of the engines. The fixed main undercarriage legs were inline with the engines, with no brakes and a simple tail skid. The Autoplane was fitted with a control system by which all manoeuvres could be carried out using one hand. At the top of each of the normal control columns there was a small wheel which took the place of the more usual rudder bar or pedals. No wing flaps or pilot-operated trimmers were provided.

Operational history
Registered G-AEOG, an Authorisation to Fly was issued on 16 October 1936, and the Autoplane was piloted by Edmund Hordern on its first flight at Heston Aerodrome on 28 October 1936. It was based at Goodwood airfield after flight testing at Heston. It was owned by the Duke of Richmond and Gordon until 14 April 1938, and then by Hordern-Richmond Aircraft Ltd at Denham Aerodrome. The aircraft's colour scheme is believed to be as follows: Fuselage, fin, rudder and nacelles dark blue, lettering G-AEOG with a white outline. Wings and stabiliser silver with dark blue lettering. It was grounded during World War II. Hordern-Richmond merged with Lang Propellers of Weybridge, and a new factory was built at Haddenham, near Thame, Buckinghamshire. The engineless remains of the Autoplane were stored in the roof of the Haddenham factory, but further details of its fate are not known.
