AquaFence. AquaFence is a reusable temporary flood and hurricane barrier made by the Norwegian manufacturer AquaFence. It is an alternative to other temporary floodwater control such as sandbags and to the building of permanent seawalls.

Design 
The fencing consists of interlocking panels which are waterproof and puncture-resistant, can be bolted down to resist winds, and use the weight of floodwater to hold them in place. Materials include marine-grade laminate, stainless steel, aluminum and reinforced PVC canvas. The panels are reusable and can be stored flat between uses. The technology was designed as an alternative to building seawalls or placing sandbags in the path of floodwaters.

Deployment 

An AquaFence was deployed at the Tees Barrage.

An AquaFence was deployed in Mount Vernon, Washington, in 2008.

Tampa, Florida's only Level I trauma center is at Tampa General Hospital, which sits directly on Tampa Bay at the northern end of the Davis Islands, which are one of the city's lowest-elevation areas. The hospital employs an AquaFence when a hurricane is forecast; erecting the fence requires 60 workers for three days. The fence the hospital uses can withstand storm surges of  and wind speeds of  per hour, which can handle a category 3 hurricane. The hospital used the fence for the first time during 2022's category 5 Hurricane Ian. During 2023's category 4 Hurricane Idalia the fence allowed about two feet of water through. It was also deployed during 2024's category 3 Hurricane Helene, successfully protecting the hospital. It was deployed for 2024's Hurricane Milton.

AquaFences have also been used to protect private properties such as luxury homes in flood-prone or hurricane-prone areas.

Company 
AquaFence was founded in 1999 and is headquartered in Oslo, Norway.

Porter Gyropachute. The Porter Gyropachute was a 1910s experimental direct-lift machine designed by James Robertson Porter.

Design and development
James Robertson  Porter  was an Australian-born civil engineer, resident in the United Kingdom, who became interested in flight in the mid-1900s.  He developed a series of un-crewed test-rigs which incorporated  annular fans fitted with vertical blades, drawing air down and through a set of two superimposed annular surfaces.

Porter's fourth, and first full-size, craft was called the Gyropachute. It consisted primarily of two superimposed parachute-shaped  surfaces.  An opening of  diameter in the uppermost surface allowed air to be drawn in by  wide impeller, fitted with vertical blades, powered by a  Gnome rotary engine. The air would be expelled out through an annular shroud created by the lowermost surface, creating lift. Segmented flexible skirts arranged around the circumference of the outer shroud could be controlled by the pilot, via a steering wheel, to manoeuvre the craft.

The Gyropachute was exhibited at the 1913 Olympia Aero Show. It is not known if the craft was tested, or if it flew.

The company is a subsidiary of AviChina Industry & Technology.

Background 
In 1970 during the Third Front, the predecessor of Jonhon was established as an electronics factory in Yichuan County, Henan that produced aviation bolts for the Chinese military. After the Chinese economic reform that opened up China in 1980, the country focused on the economy and the factory which relied on producing military products struggled. The factory spent years gathering capital mainly from loans to move to Luoyang City.

In 1991, the factory moved to Luoyang and focused on producing electrical connectors, optical fiber connectors and other products for cvillian usage. In 1995 it passed the ISO 9001 standard.  Afterwards the factory's business expanded rapidly. In 2002 with China Aviation Industry Corporation I as the initiator along with six other units, the factory was restructured to become a joint-stock company named China Aviation Optical-Electrical Technology.

In 2007, the company held its initial public offering becoming a listed company on the Shenzhen Stock Exchange. It was the first company in China related to national defense to become a publicly listed.

In 2012, the company along with Hisense Broadband formed AVIC Hisense Photoelectric Technology (now known as Qingdao Xinghang Photoelectric Technology) to expand the fiber optic connector business. In 2013, it acquired 48.18% stake in Xian Forstar S&T (now AVIC Forstar S&T) which is currently listed on the Beijing Stock Exchange. In 2015, it established a joint venture named AVIC Optoelectronics Precision to produce precision connectors.

On 6 July 2016, the company changed its name to AVIC Jonhon Optronic Technology Co., Ltd.

On 4 June 2021, US president Joe Biden signed Executive Order 14032 that listed 59 Chinese companies that are to be banned from receiving U.S. investments. Jonhon was one of the companies on the list.

AviChina Industry & Technology. AviChina Industry & Technology (AviChina; ) is a partially state-owned publicly listed aviation company headquartered in Beijing. It primarily is involved with aircraft manufacturing, supplying aviation Ancillary Systems and providing aviation engineering services.

The company is a subsidiary of the Aviation Industry Corporation of China (AVIC).

Background 
AviChina was established on 30 April 2003. It was previously the civil unit of China Aviation Industry Corporation II. As of 2003 it was the largest minicar maker in China with a 41 percent market share as well as the only domestic mass producer of helicopters and regional jets in China. Although the car business made up 80% of its revenue in the previous year it expected its aircraft assembly business to drive future growth. AviChina held 49 percent of a joint venture with Embraer to build jets in China. It also had partnerships with Sikorsky Aircraft and Eurocopter to make helicopters

On 30 October 2003, AviChina held its initial public offering becoming a listed company on the Hong Kong Stock Exchange. It raised US$247 million.

For 2007, AviChina reported a loss of 1.03 billion yuan due to a bigger deficit at its vehicle division and decline in margins at its helicopter unit. Its vehicle division consisted of two units, Hafei Automobile and  Changhe. In 2009, AviChina became a purely aeronautical company after it sold Hafei to its parent AVIC in exchange for its avionics electronics business and spunoff Changhe. In 2010, AviChina management said it intended to gradually buy all of its parent's aviation equipment operations.

In April 2018, Bloomberg News reported that AviChina was one of the best performing stocks in Asia. From the start of February to April it had rose 40% which put it at the top of the MSCI Asia Pacific Index that fell more than 6 percent in that time. Due to tensions in China–United States relations there was renewed investors’ interest in Chinese defense stocks. Its military revenue outpaced profits from general-purpose lightweight aircraft used for cargo transport and crop seeding. Airbus was a significant shareholder with a 11.7% stake.

In January 2023, Norway's sovereign wealth fund, Norges Bank Investment Management said it had divested from AviChina for selling light aeroplanes to military junta-ruled Myanmar.

Death of Sabekun Nahar Sonny. Death of Sabekun Nahar Sonny refers to the death of Sabekun Nahar Sony, a student of Bangladesh University of Engineering and Technology, in the crossfire of a gunfight between fractions of Bangladesh Jatiotabadi Chatra Dal on 8 June 2002.

Background
Bangladesh Jatiotabadi Chatra Dal is the student wing of the Bangladesh Nationalist Party.

Sabekun Nahar Sonny 
Sonny's father was Habibur Rahman Bhuiyan (died 2023). She was a second year student of the department of chemical engineering of the Bangladesh University of Engineering and Technology.

Incident

Two factions of the Bangladesh Jatiotabadi Chatra Dal, student wing of the governing Bangladesh Nationalist Party, were engaged in a gunfight on the campus of Bangladesh University of Engineering and Technology. She was shot in the crossfire and died. She was standing in front of Ahsanullah Hall of the university. The two sides were fighting over tender. One fraction was led by Mokammel Hayat Khan, president of the campus unit of Bangladesh Jatiotabadi Chatra Dal, and the other fraction was led by Mushfique Uddin Tagar, leader of the SM Hall of the Chatra Dal.

There were protests across Bangladesh following her death.

Trial

Sonny's father accused the Bangladesh Nationalist Party government, police and the administration of the Bangladesh University of Engineering and Technology supporting the accused.

The trial for the murder case took place in the Speedy Trial Tribunal-1 under judge Shahed Noor Uddin. On 29 June 2003, the court sentenced three to death and five to life imprisonment.

In March 2006 Bangladesh High Court reduced the death sentences to life sentences to three accused fugitives in the murder case on appeal. Four convicts in the case are in jail while two are absconding. Two of the convicts sentenced to life imprisonment were acquitted.

Legacy 
The university campus observes 8 June at the anti-terrorism day. On 4 November 2021, the only female dormitory of the Bangladesh University of Engineering and Technology was named Sabequn Nahar Sony Hall.

The Daily Star lamented that following the murder of Abrar Fahad his family was given compensation but did was not the case after the Murder of Arif Raihan Dwip and death of Sabekun Nahar Sonny. It also noted the sole accused in the death of Arif Raihan Dwip was not arrested and two accused in the death of Sabekun Nahar Sonny had not been detained in 20 years. Her death was one of the reasons cited for students opposing politics on the campus of Bangladesh University of Engineering and Technology.

Electromagnetically enhanced Physical Vapor Deposition. Electromagnetically-enhanced Physical Vapor Deposition (EPVD) is coating technique developed by Paradigm Shift Technologies, Inc.  which uses electromagnetic fields to improve traditional physical vapor deposition, particularly in high-stress applications like gun barrel coatings.

History 
EPVD technology was developed by Paradigm Shift Technologies, Inc., a Canadian company founded in 1995. It was invented to replace the traditional chrome plating.

Thin-film deposition is the overarching technology from which PVD, CVD, ALD, EBPVD, and EPVD are derived, each employing different methods to achieve specific coating characteristics. PVD (Physical Vapor Deposition) involves the physical vaporization of material in a vacuum to form a thin film, while EBPVD (Electron Beam Physical Vapor Deposition) uses an electron beam to vaporize the source material more efficiently.

EPVD (Electro-magnetically enhanced Physical Vapor Deposition), on the other hand, enhances the standard PVD process by utilizing electromagnetic fields to guide the deposition. This allows coatings to be applied to non-line-of-sight internal surfaces, such as the interiors of tubular components, resulting in much thicker, more robust, and uniform coatings compared to traditional PVD methods. This advanced process not only improves the durability of the coating but also enables the use of these coatings in more complex geometries, making it highly advantageous in industries requiring extreme wear resistance

Process overview 
EPVD involves vaporizing the coating material in vacuum and depositing it onto the substrate. Electromagnetic fields are applied to control the deposition rate and ensure uniform coating thickness, resulting in superior coating properties. In this process, the material is removed from a target made from the refractory alloy and deposited on the bore of the gun barrel in a low-pressure, inert environment.

The EPVD process generates thick coatings (50 to 300 microns) needed for gun barrels and can be adapted for small, medium, and large calibers. It applies engineered multilayer coatings using mostly metallic or ceramic materials, predominantly featuring tantalum, tungsten, and other refractory metals.

Applications 
EPVD technology is mainly used in the defense industry for coating gun barrels, enhancing accuracy, durability, and lifespan under high-stress conditions.

Beyond defense, EPVD is applied in aerospace for turbine blades and engine components to improve temperature and wear resistance. The automotive industry uses it to enhance engine and transmission parts, while petrochemical, industrial machinery, and medical device sectors benefit from increased durability and biocompatibility in surgical instruments and implants.

Advanced Unmanned Search System. The Advanced Unmanned Search System (AUSS) was a submersible employed by the United States Navy constructed from a carbon-fiber reinforced plastic cylinder with titanium semi-spheres at the ends. The vessel measured  in length, and was  wide.

It was able to operate at depths of up to , autonomously and untethered. Commands were send to the craft via sonar modem at a bitrate of 1,200 bits per second (bit/s), and the AUSS sent back data at rate of 4,800 bit/s. The controllers at the surface defined the targets and the search patterns, while the submersible executed the search patterns autonomously, without any realtime inputs.

Its silver-zinc batteries allowed an endurance of 10 hours, while recharging lasted 20 hours. The AUSS navigated with a gyrocompass and Doppler sonar.

Replicator (United States military). Replicator is the name of a United States Department of Defense program intended to pioneer ways to cheaply produce large amounts of weapons or systems for the U.S. military.

It was announced on Aug. 23, 2023, by Deputy Defense Secretary Kathleen Hicks as a means of quickly producing weapons to deter and counter China. In her announcement, Hicks said the first type of weapons to be produced under Replicator were to be autonomous systems; she did not specify whether these would be, for example, aerial drones or unmanned vessels.

The Replicator program announced its first batch of contracts on May 6, 2024; they included purchases of uncrewed watercraft, aerial drones, and anti-drone defenses "of various sizes and payloads from several traditional and non-traditional vendors." Some other contracts “remain classified, including others in the maritime domain and some in the counter-UAS portfolio”, a Defense Department release said.

On September 30, 2024, Defense Secretary Lloyd Austin III announced a new phase of the program, dubbed Replicator 2, that would focus on anti-drone defensive systems.

GPTs. GPTs are customizable applications based on the Artificial Intelligence, abbreviated as AI, language model of ChatGPT that can perform a wide variety of tasks tailored to specific needs. GPTs can be used and created from the GPT Store. Any user can easily create them without any programming knowledge. By January 2024, more than 3 million GPTs had already been published.

Features and uses 
GPTs can be configured to answer complex questions in specific fields, solve problems, provide image-based information, or create digital content. They can be programmed as educational tools, purchasing guides, or technical advisors, as well as for many others applications. 

GPTs are accessed from the GPT Store section of the chatGPT web page. The “Explore GPT” link opens the store where the most popular GPTs in each section are highlighted. The GPTs are organized by categories. The store also uses a rating system based on user experiences similar to that used by other App stores such as Apple’s App Store or Google Play. Those with the best ratings appear at the top of each category.

According to La Vanguardia, the most popular categories are:

 Personal assistants
 Learning to program
 Image generation
 Creative writing
 Gaming
 Entertainment

It is expected that in the future the creators of GPTs will be able to monetize them.

Companies like Moderna are using GPTs to assist in various specific business tasks. The company has created 750 GPTs for its own internal use.

Configuration 
Installing GPTs is a simple task that does not require prior programming knowledge. Free users can use existing GPTs but cannot customize their own.  Paying subscribers, can use a “Create a GPT” link at the page chat.openai.com/gpts/editor where they can specify the title and description and upload an image or ask the artificial intelligence to automatically create one based on the title and description. The process also involves specifying the GPT’s objective and how it should behave along with “conversation starters” which are phrases to activate it. Optionally, APIs can be triggered using the “Add actions” option. There are three publication options: Public, private or accessible only to people with a link..

Criticism 
The implementation and use of GPTs has not been without criticism. The main concerns are ethics and the accuracy of the information generated. The GPT Store has been criticized for the proliferation of low-quality GPTs and spam due to a lack of effective moderation. There are also concerns about data privacy and security, as GPTs may collect and use personal information in ways that are not always transparent to users.
