SCMOS. sCMOS (scientific Complementary Metal–Oxide–Semiconductor) are a type of CMOS image sensor (CIS). These sensors are commonly used as components in specific observational scientific instruments, such as microscopes and telescopes. sCMOS image sensors offer extremely low noise, rapid frame rates, wide dynamic range, high quantum efficiency, high resolution, and a large field of view simultaneously in one image.

The sCMOS technology was launched in 2009 during the Laser World of Photonics fair in Munich. The companies Andor Technology, Fairchild Imaging and PCO Imaging developed the technology for image sensors as a joint venture.

Technical details 
Prior to the introduction of the technology, scientists were limited to using either CCD or EMCCD cameras, both of which had their own set of technical limitations. While back-illuminated electron-multiplying CCD (EMCCD) cameras are optimal for purposes requiring the lowest noise and dark currents, sCMOS technology's higher pixel count and lower cost result in its use in a wide range of precision applications. sCMOS devices can capture data in a global-shutter “snapshot” mode over all the pixels or rectangular subsets of pixels, and can also operate in a rolling-shutter mode.

The cameras are available with a monochrome sCMOS image sensors or with RGB sCMOS image sensors. With sCMOS, digital information for each frame is generated rapidly and with an improved low-light image quality. The sCMOS sensor's low read noise and larger area provides a low-noise, large field-of-view (FOV) image that enables researchers to scan across a sample and capture high-quality images.

Some disadvantages at this time, (2023), with sCMOS cameras versus related technologies are:

 sCMOS sensors tend be more expensive than traditional CMOS sensors.
 sCMOS sensors have a limited resolution compared to other types of sensors like CCD.

In practice 
The New York University School of Medicine uses sCMOS cameras for their research. They were used to study biological molecules and processes in real-time at nanometer scale. Such cameras were also in use in astronomy and microscopy.

Zaca a te Moana (schooner). The yacht Zaca A Te Moana is a schooner with fore-and-aft rig built in 1992 at Ouderkerk aan de Amstel, in Netherlands. The naval architect is Olivier Van Meer,  and the interior architect is Ed Kastelein.

Dimensions 
The overall length is 43,8 meters, 7,2 meters of width and 4,3 meters for the draught. It has got sails surface of 815m², her cruise speed is 8 knots and her maximal speed is 11 knots.

Her tonnage is 175 tons because of her steel hull that offer a solid and sturdy structure, the deck and the superstructure are in teak. This sailing ship has a Rolls-Royce motor with 6 cylinders of 220Kw(300 horses power) working with Marine diesel.

The Zaca concept 
The architecture of the yacht is based on the sailing ship Zaca, this is the property of the actor Errol Flynn, built in 1930. It was registered at Jersey and Saint-Hélier is her home port. This ship was restored, during the 90's years and today it does some parade in the port of Monaco in mediterranean. Zaca A Te Moana is the little brother with her age, but is more bigger in size.

Ship activities 
This yacht is a luxury boat which can have as a guest 12 persons on board additional to the 8 crew members. After sailing in the Caribbeans, it was moored in 2015 at Zeebruges, in the pleasure-sailing port of the Royal Belgian Sailing Club (RBSC).

Until 2015 this yacht sailed regularly in the Caribbean where it participated at the St.Martin Classic Regatta  and in Mediterranean too, with 4 fix crew members and 4 occasional crew members. At the time, the ship should leave to Antwerp to be restored at the 138 quay : only the cabin, the masts ad the riggings with stay from the origin, the remaining parts shall be reorganized to bring more space and comfort on board. Since this time, it has been moored in the pleasure-sailing port at Antwerp.

Supply-class replenishment oiler. The Supply class is a class of replenishment oilers of the Royal Australian Navy, a role that combines the missions of a tanker and stores supply ship. As such they are designated auxiliary oiler replenisher (AOR). They are tasked with providing ammunition, fuel, food and other supplies to Royal Australian Navy vessels around the world. There are two ships in the class,  and . The project is expected to cost anywhere between $1 and $2 billion. Navantia were selected to build a design based on the Spanish Navy's current replenishment vessel , which entered service in 2011.

Planning

A number of designs were considered by the Australian Government for their replacement tankers, with Navantia competing against the Aegir variant of the  built by South Korea's DSME in a restricted tender competition. Navantia's proposal based on Cantabria was announced as the successful design in the Australian tender in March 2016, with an expected in service date for the first of two vessels of late 2019.

Construction
The class of ships based on Navantia's replenishment oiler were built at the Navantia shipyard in Ferrol, Spain. The first ship, Supply, arrived at Fleet Base West in October 2020 to begin fitting Australia-specific equipment prior to her service entry in April 2021.

The second ship, Stalwart, departed for Australia in May 2021 and arrived in late June.

Operational history
HMAS Supply commissioned at Fleet Base East on 10 April 2021.

HMAS Stalwart commissioned at Fleet Base West on 13 November 2021.

Mechanical defects

In March 2023, a mechanical defect relating to the shaft alignment was found on HMAS Supply. The ship returned to Garden Island where it was to be repaired by Navantia under warranty.

In June 2024, it was reported that HMAS Supply could remain out of service for another year despite being sidelined for repairs over 14 months previously. In the same month, it was reported that HMAS Stalwart had been sidelined due to mechanical problems relating to its engine. As a result, the Royal Australian Navy currently has no operational replenishment oilers as of 2024. The vessels were anticipated to remain out of service until 2025.

Electrical busbar system. Electrical busbar systems (sometimes simply referred to as busbar systems) are a modular approach to electrical wiring, where instead of a standard cable wiring to every single electrical device, the electrical devices are mounted onto an adapter which is directly fitted to a current carrying busbar. This modular approach is used in distribution boards, automation panels and other kinds of installation in an electrical enclosure.

Busbar systems are subject to safety standards for design and installation along with electrical enclosure according to IEC 61439-1 and vary between countries and regions.

Content & types of busbar systems 

A busbar system usually contains couple of busbar holders, busbars, Adapters to mount devices, clamps either with protective covering or without covering to powerup or distribute the current from the busbar system & busbar mountable electrical devices.

Electrical busbar systems can be differentiated by the distance between center of each busbar and vary according to maximum current carrying capacity of the system which depends on IEC standards. commonly known busbar system types.

 40 mm Busbar System (Current carrying capacity up to 300–400 Amps) 
 60 mm Busbar System (Current carrying capacity up to 800–2500 Amps)
 100 mm Busbar System (Current carrying capacity up to 1250 Amps)
 185 mm Busbar System (Current carrying capacity up to 2500 Amps)

DOST Hybrid Electric Road Train. The Hybrid Electric Road Train (HERT) is a hybrid trackless train developed by the Department of Science and Technology of the Philippines for public transport. The headquarter office is located at New Clark City under the town of Capas, Tarlac, Philippines.

Background

The Hybrid Electric Road Train (HERT) was developed by the Metals Industry Research and Development Center (MIRDC) of the Department of Science and Technology (DOST), and is part of the science agency's Advanced Transport Program under the Makina at Teknolohiya Para Sa Bayan (MakiBayan; ) Program. It was designed by Filipino engineers using locally available parts. It was meant to be an alternative to the mass transport system in metropolitan areas experiencing heavy traffic congestion.

On August 11, 2021, the DOST signed an agreement with an Ilagan-based consortium for the manufacturing of the HERT in Isabela.

Specifications
The Hybrid Electric Road Train consists of five interlinked coaches with air-conditioning and runs on a combination of diesel fuel and electrical power via a 260-battery generator. Described as a "road train", the HERT operates on roads and does not run on railways. It measures  long, and has a maximum speed of . Four of the train's coaches are meant for transporting passengers while a lone coach hosts the engine. Each coach has a capacity of 60 people for a total capacity of 240 passengers per trip. The HERT devises a regenerative brake.

There are two variants of the Hybrid Electric Road Train: the 160-passenger variant and the bigger 240-passenger variant.

Operational history
The Hybrid Electric Road Train was officially launched by the DOST on August 22, 2014. and had its "soft launching" at the Clark Freeport Zone on June 25, 2015 at the Clark Freeport Parade Ground, where it was tested.

In May 2015, the representatives of local government of Cebu City and the DOST signed a memorandum of understanding to work on the integration of the HERT into the city's public transport system. It was also demonstrated during the opening day of the National Science and Technology Week in Pasay in July 2015.

By 2016, the train with modifications has already been adopted by the Clark Development Corporation to serve employees of its 1,000 business locators at the Clark Freeport and Special Economic Zone. On February 5, 2016, the train was demonstrated as part of EDSA Evolution, a road-sharing project by the Bayanihan sa Daan Movement and various government agencies. As part of the demonstration, passengers were transported from the SM Mall of Asia in Pasay to the Museo Pambata at the Luneta Park in Manila.

The HERT had its maiden demonstration run in General Santos on November 15, 2017 as a prelude to a trial run of the vehicle for as long as five months.
