AI based Hypersonic missile development

 The National Aeronautics and Space Administration (NASA) has developed Artificial Intelligence that would help it in building a hypersonic missile in what could be a big breakthrough in America’s hypersonic program.

A hypersonic missile being developed in the US is supposed to make use of a technology known as ‘scramjet’ or ‘supersonic combustion ramjet’ to make optimum use of fuel, reach hypersonic speed, and cause maximum devastation on impact, as the use of traditional, heavy rockets and spacecraft limit its application.

The scramjet uses extremely effective thrust mechanisms to achieve much faster speeds, and it can be manufactured in a size much smaller, lighter, and with a longer range than traditional rockets. This is where the role of Artificial Intelligence comes in the development of a hypersonic missile.

This AI may build a hypersonic missile that is significantly faster and has a wider range than any other in the world, propelling the United States to the forefront of the military arms race. All they have to do now is apply this AI to the Hypersonic Air-breathing Weapon Concept tested recently, load it up with explosives, and take off.

NASA is said to have developed artificial intelligence (AI) capable of optimizing missiles for maximum range and destruction. It has developed an AI that can use the results of a computational fluid dynamic (CFD) to optimize and work around an effective design of a scramjet missile.

Pak china cooperation in sorghum

 Sorghum is an excellent source of food and feed and plenty of products can be made from it therefore, there are ample opportunities for the sorghum industry in Pakistan and help of China would definitely improve the local economy.

mutual cooperation between the two countries can be strengthed by long-term and short-term cooperation, seeking the future opportunities for expansion of sorghum production, export and development in Pakistan. There is a need to take advantage of Chinese technology and experience under the China-Pakistan Economic Corridor in this field.

Since China is a major importer of sorghum grain for manufacturing of various products, there is plenty room to expand the export of the commodity to China. Secondly, the quality of sorghum grain produced in Pakistan for processing and extraction of different products is far better than that of other countries.

Zumwalt: us navy stealth destroyer

Zumwalt-classAn artist rendering of the Zumwalt class destroyer DDG 1000, a new class of multi-mission U.S. Navy surface combatant ship designed to operate as part of a joint maritime fleet, assisting Marine strike forces ashore as well as performing littoral, air and sub-surface warfare.

The Zumwalt-Class Destroyer Fell Short of Expectations – The United States Navy’s Zumwalt-class destroyer was billed as the future of naval warfare. Designed to incorporate brand new stealth technology, and brand-new weapons systems, the Zumwalt was to replace the aging Arleigh Burke-class. Initially, the Navy was scheduled to procure 32 Zumwalts. But the program went rampantly overbudget while the new ship performed below expectations. The Navy withdrew support, asking Congress to stop procuring Zumwalts and instead build more of the familiar, reliable Arleigh Burke destroyers. Congress obliged and only three Zumwalts were ever delivered

The Zumwalt-Class Destroyer Fell Short of Expectations – The United States Navy’s Zumwalt-class destroyer was billed as the future of naval warfare. Designed to incorporate brand new stealth technology, and brand-new weapons systems, the Zumwalt was to replace the aging Arleigh Burke-class. Initially, the Navy was scheduled to procure 32 Zumwalts. But the program went rampantly overbudget while the new ship performed below expectations. The Navy withdrew support, asking Congress to stop procuring Zumwalts and instead build more of the familiar, reliable Arleigh Burke destroyers. Congress obliged and only three Zumwalts were ever delivered. 

The Zumwalt was an ambitious project, full of innovative technology. For starters, the Zumwalt was a stealth ship. Despite being 40 percent larger than the Arleigh Burke, the Zumwalt has a radar cross-section (RCS) comparable to a fishing boat. The key to such a deceptive RCS is the Zumwalts hull design. The Zumwalt’s hull grows narrower above the waterline, in a tumblehome style. The tumblehome was common on wooden warships and had a flare of popularity with steel warships in the late 19th century. But when three of four Russian tumblehome battleships were lost in the Russo-Japanese War, the design was declared ineffective for modern warfare and fell out of style for nearly one hundred years. Now, stealth-seeking modern navies are reintroducing the shape to meet low-RCS requirements. 

In addition to the tumblehome design, the Zumwalt has a composite deckhouse, which encases the ship’s sensory and electronic equipment in low RCS material. Between the tumblehome hull and the composite deckhouse, the Zumwalt’s RCS is about 50 times harder to detect on radar than older destroyers. And the Zumwalt is quiet—with an acoustic signature more similar to a Los Angeles-class submarine than a surface warship.     

However, the applicability of the Zumwalt’s stealth has been called into question. The Zumwalt was designed to provide Naval Surface Fire Support with a focus on land attacks. So, the Zumwalt was meant to operate in typically crowded, near-shore waters where ships can be tracked visually. And the Zumwalt, naturally, was intended to fire its impressive arsenal—meaning, that once the ship started firing, its stealth properties would be compromised. .

Yj21 Chinese Anti ship ballistic missile

 Hi, What Are You Looking For?

China’s YJ-21 Anti-Ship Missile Test Warns Washington: Taiwan Isn’t Ukraine – China’s test of a new anti-ship missile may be sending America a message: Taiwan isn’t Ukraine.

Chinese leaders may fear that Ukraine’s success in frustrating Russia’s invasion – partly based on military aid from NATO nations – will encourage Taiwan into believing that U.S. support will allow it to defeat a Chinese invasion.

“Beijing is worrying that the unlimited U.S. military assistance to Ukraine and a recent American congressional group tour to Taiwan might make Taipei believe Washington may provide the same help in the event of a conflict between the mainland and Taiwan,” Chinese military expert Zhou Chenming, told the South China Morning Post.

As a matter of military technology, attention will be paid to the video of the mysterious YJ-21 anti-ship ballistic missile (ASBM), released by the Chinese government for the first time. Perhaps more notable was that the YJ-21 – or Eagle Strike 21 – was launched from a new Type 055 cruiser. China already has land-based anti-ship ballistic missiles – the notorious DF-21 and DF-26 “carrier killer” weapons – as well as an air-launched ASBM on the H-6 bomber.

Not surprisingly, these ASBMs deeply worry the U.S. Navy. With ranges of more than a thousand miles, they soar high into the atmosphere before releasing a warhead at hypersonic (faster than Mach 5) speed that may be too fast for shipboard anti-missile defenses to stop.

An ASBM capable of being launched by surface ships would be a powerful weapon. Unlike land-based missiles that are fixed platforms, or aircraft with limited range and vulnerability to bad weather, surface ships provide mobile launch platforms. An ASBM-equipped Chinese task force, for example, could penetrate into the Indian Ocean, or into the South Pacific to threaten Australia. Mounted on the 13,000-ton Type 055, a heavily armed destroyer that is actually bigger than a U.S. Navy Aegis cruiser, the YJ-21 could threaten U.S. and coalition ships across the Pacific. 

Using social media Applications

A FRENCH SOCIAL media platform launched by Alexis Barreyat in 2020, BeReal is attracting dedicated users on US college campuses after gaining popularity overseas. Essentially, BeReal sends users a prompt at a random time each day, urging them to snap a picture and send it to their friends. You only have two minutes to respond, and a two-image collage is captured from your front and back cameras. has been declared dead multiple times, and BeReal capitalizes on a continuing quest for authenticity on social media, whatever that means. The company has received millions of dollars from investors likeAndreessenHorowitz, a prominent player in Silicon Valley that has thrown cash at Clubhouse, OpenSea, and Substack in recent years. In February, Harvard student Mariah Norman declared photo dumps on Instagram a passé endeavor so mainstream that the president does it. She was enamored by the unfiltered feed on BeReal and wrote, “Because there’s no time to find that perfect pose or background, the content you engage with on the app is charmingly mundane yet extraordinarily authentic and creative.” Norman also mentioned that BeReal sponsored a party with free admission for Harvard students who interacted with the app.

Global warming

 

Global warming

John Houghton

Reports on progress in physics 68 (6), 1343, 2005

'Global warming'is a phrase that refers to the effect on the climate of human activities, in particular the burning of fossil fuels (coal, oil and gas) and large-scale deforestation, which cause emissions to the atmosphere of large amounts of'greenhouse gases', of which the most important is carbon dioxide. Such gases absorb infrared radiation emitted by the Earth's surface and act as blankets over the surface keeping it warmer than it would otherwise be. Associated with this warming are changes of climate. The basic science of the'greenhouse effect'that leads to the warming is well understood. More detailed understanding relies on numerical models of the climate that integrate the basic dynamical and physical equations describing the complete climate system. Many of the likely characteristics of the resulting changes in climate (such as more frequent heat waves, increases in rainfall, increase in frequency and intensity of many extreme climate events) can be identified. Substantial uncertainties remain in knowledge of some of the feedbacks within the climate system (that affect the overall magnitude of change) and in much of the detail of likely regional change. Because of its negative impacts on human communities (including for instance substantial sea-level rise) and on ecosystems, global warming is the most important environmental problem the world faces. Adaptation to the inevitable impacts and mitigation to reduce their magnitude are both necessary. International action is being taken by the world's scientific and political communities. Because of the need for urgent action, the greatest challenge is to move rapidly to much increased energy efficiency and to non-fossil-fuel energy sources.
