India Meteorological Department forecasts slightly delayed Southwest monsoon – 2016 over Kerala
India Meteorological Department forecast suggests that the onset of Southwest monsoon this year over Kerala is likely to be slightly delayed. The statistical model used by IMD, for predicting the onset of monsoon, indicates that the southwest monsoon is likely to set over Kerala on 7th June with a model error of ± 4 days.
The below mentioned components for data modelling is important from examination perspective.
The onset of southwest monsoon over Kerala signals the arrival of monsoon over the Indian subcontinent and represents beginning of rainy season over the region. The normal monsoon onset over Kerala is 01 June. Since 2005, India Meteorological Department (IMD) has been issuing operational forecasts for the date of monsoon onset over Kerala using an indigenously developed statistical model with a model error of ± 4 days. The model uses the following six predictors:
i) Minimum Temperatures over North-west India,
ii) Pre-monsoon rainfall peak over south Peninsula
iii) Outgoing Long wave Radiation (OLR) over south China Sea
(iv) Lower tropospheric zonal wind over southeast Indian ocean
(v) upper tropospheric zonal wind over the east equatorial Indian Ocean
(vi) Outgoing Long wave Radiation (OLR) over the south-west Pacific region.
Some issues relating to advance of monsoon over the Andaman Sea
The southwest monsoon advances over the Andaman Sea normally around 20th May with a standard deviation of about one week. Strong convective activity has been observed over the equatorial Indian Ocean for the last several days. A well marked low pressure area has formed over the Indian Ocean which will concentrate into a depression and move north-westwards. As a result, conditions are becoming favorable for the onset of southwest monsoon over Nicobar Islands, south Andaman Sea and parts of south Bay of Bengal around 17th May and advancement over the entire Andaman Sea close to its normal date. Past data suggest that there is no association of the date of monsoon advance over the Andaman Sea either with the date of monsoon onset over Kerala or with the seasonal monsoon rainfall over the country.
India and WHO sign a landmark agreement for Global promotion of Traditional Systems of Medicine:-
Ministry of AYUSH, Government of India and the World Health Organization (WHO) have signed an historic Project Collaboration Agreement (PCA) for cooperation on promoting the quality, safety and effectiveness of service provision in traditional and complementary medicine.
Speaking at a Reception hosted by India on this occasion, the AYUSH Minister recalled the long history and rich heritage of traditional medicine in India and its growing relevance in providing holistic and comprehensive health care. He reiterated the high priority attached by the Government of India for the promotion of traditional medicine both in India and abroad and highlighted the numerous initiatives undertaken to functionally integrate AYUSH in India’s national health programmes and for achieving Universal Health Coverage.
The Minister also mentioned that the initiatives and activities undertaken by India within the country align with the WHO Traditional Medicine Strategy 2014-2023. He added that India, in fact, sets a unique example for adopting a pluralistic health care delivery system that allows every recognized medical system to develop and be practiced with a view to provide integrated and holistic healthcare services.
The PCA with WHO is a further recognition of India’s rich experience in the development and governance of traditional medicine. It will pave the way for India’s long-term collaboration with the WHO in fostering the global promotion and integration of AYUSH systems of medicine including through the inclusion of Ayurveda and Unani in the International Classification of diseases and the International Classification of Health interventions.
Exercise Red Flag:
Red Flag Alaska 16-1, which was anadvanced aerial combat training exercise hosted at Eielson Air Force Base, Alaska (a successor to the previous COPE THUNDER exercise series) held in the Alaska region. Indian Air force is a participant.Objective of this inter-continental deployment was not only to showcase IAF capability in undertaking Integrated Air Ops but also to imbibe operational lessons from the exercise engagements which will help us add more teeth to our overall war waging capabilities”.
ISRO embarks on launching Indian space shuttle
Indian Space Research Organisation (ISRO) is all set to undertake the maiden launch of its ‘space shuttle’, a fully made-in-India effort. A sleek winged body, almost the weight and the size of sports utility vehicle (SUV), is being given final touches at Sriharikota where it awaiting final countdown.
Here’s what we know:
India’s space port at Sriharikota on the coast of the Bay of Bengal in Andhra Pradesh will witness the launch of the indigenously made Reusable Launch Vehicle-Technology Demonstrator (RLV-TD). After the launch, it will be glide back onto a virtual runway in the Bay of Bengal.
The RLV-TD is unlikely to be recovered from sea during this experiment as it is expected that the vehicle will disintegrate on impact with water since it is not designed to float.
The purpose of the experiment is to help the shuttle glide over a virtual runway in the Bay of Bengal, situated 500 km from the coast.
India’s frugal engineers believe the solution to reducing cost of launching satellites into orbit is to recycle the rocket or make it reusable.
Scientists at ISRO believe that they could reduce the cost by as much as 10 times if reusable technology succeeds, bringing it down to $2,000 per kg.
K. Sivan, director of the Vikram Sarabhai Space Centre, Thiruvananthapuram, says, “These are just the first baby steps towards the big Hanuman leap.”
The final version will take at least 10-15 years to get ready.
The special booster or the first stage is powered using a solid fuel and it will hoist the RLV-TD prototype to about 70 km into the atmosphere from where the descent will begin.
During the descent phase, small thrusters will help the vehicle navigate itself to the landing area.
The making of the Indian space shuttle or RLV-TD has taken five years and the government has invested Rs. 95 crore in the project. This flight will test the capability of the vehicle to survive a re-entry at speeds higher than that of sound.
An ingestible origami robot
In experiments involving a simulation of the human oesophagus and stomach, researchers at the Massachusetts Institute of Technology, the University of Sheffield, U.K., and the Tokyo Institute of Technology have demonstrated a tiny origami robot that can unfold itself from a swallowed capsule and, steered by external magnetic fields, crawl across the stomach wall to remove a swallowed button battery or patch a wound.
Every year, 3,500 cases of people having swallowed button batteries are reported in the United States alone. Frequently, the batteries are digested normally, but if they come into prolonged contact with the tissue of the oesophagus or stomach, they can cause an electric current that produces hydroxide, which burns the tissue. However, in the researchers’ project, there will be uses for such robots that go beyond buttons.
Darknet, also known as dark web or darknet market, refers to the part of the internet that is not indexed or accessible through traditional search engines. It is a network of private and encrypted websites that cannot be accessed through regular web browsers and requires special software and configuration to access.
The darknet is often associated with illegal activities such as drug trafficking, weapon sales, and hacking services, although not all sites on the darknet are illegal.
Examples of darknet markets include Silk Road, AlphaBay, and Dream Market, which were all shut down by law enforcement agencies in recent years.
These marketplaces operate similarly to e-commerce websites, with vendors selling various illegal goods and services, such as drugs, counterfeit documents, and hacking tools, and buyers paying with cryptocurrency for their purchases.
Anonymity: Darknet allows users to communicate and transact with each other anonymously. Users can maintain their privacy and avoid being tracked by law enforcement agencies or other entities.
Access to Information: The darknet provides access to information and resources that may be otherwise unavailable or censored on the regular internet. This can include political or sensitive information that is not allowed to be disseminated through other channels.
Freedom of Speech: The darknet can be a platform for free speech, as users are able to express their opinions and ideas without fear of censorship or retribution.
Secure Communication: Darknet sites are encrypted, which means that communication between users is secure and cannot be intercepted by third parties.
Illegal Activities: Many darknet sites are associated with illegal activities, such as drug trafficking, weapon sales, and hacking services. Such activities can attract criminals and expose users to serious legal risks.
Scams: The darknet is a hotbed for scams, with many fake vendors and websites that aim to steal users’ personal information and cryptocurrency. The lack of regulation and oversight on the darknet means that users must be cautious when conducting transactions.
Security Risks: The use of the darknet can expose users to malware and other security risks, as many sites are not properly secured or monitored. Users may also be vulnerable to hacking or phishing attacks.
Stigma: The association of the darknet with illegal activities has created a stigma that may deter some users from using it for legitimate purposes.
AI, or artificial intelligence, refers to the development of computer systems that can perform tasks that would normally require human intelligence, such as recognizing speech, making decisions, and understanding natural language.
Virtual assistants: Siri, Alexa, and Google Assistant are examples of virtual assistants that use natural language processing to understand and respond to users’ queries.
Recommendation systems: Companies like Netflix and Amazon use AI to recommend movies and products to their users based on their browsing and purchase history.
Efficiency: AI systems can work continuously without getting tired or making errors, which can save time and resources.
Personalization: AI can help provide personalized recommendations and experiences for users.
Automation: AI can automate repetitive and tedious tasks, freeing up time for humans to focus on more complex tasks.
Job loss: AI has the potential to automate jobs previously performed by humans, leading to job loss and economic disruption.
Bias: AI systems can be biased due to the data they are trained on, leading to unfair or discriminatory outcomes.
Safety and privacy concerns: AI systems can pose safety risks if they malfunction or are used maliciously, and can also raise privacy concerns if they collect and use personal data without consent.
