Understanding Breaking Codes Of Enigma Machine

By
'Enigma' is defined as 'A person or thing that is mysterious or difficult to understand'. The Enigma is considered important is its historical context. It was a widely used Cryptographic machine in Nazi submarine warfare, which was a key part of European conflict. The best cryptography, the Enigma machine is simple to describe but infuriating to break. Enigma looked from outside like an oversized typewriter.
The Turing Test - This test was framed by Alan Turing, born in 1912, was an English Mathematician and Computer Scientist is considered to be father of Computer Science. He proposed a concept of computer machine which is regarded as a model of modern computer. He played a significant role during World War II where he with his team build a machine to decode German ciphers. The success of the code breaking work helped Allies to defeat the Nazis. It is estimated that his work saved over 14 million lives.
The Enigma machine was a piece of German engineering that encrypted messages using a complex set of rules that allowed to scramble a message in a quasi - random manner that meant the only way to decrypt it would be to have the exact setting of the machine used to write the codes. The machine be programmed with the same settings, type in the encrypted message, and the original message pops out. It is like the codes one makes in where 'T' means 'B' and so on, only instead of 'T' always meaning 'B', 'T' is a different letter every single time it is pressed. This is achieved through an incredibly complicated method that includes a Plug Board that does the Direct 'Letter to Letter' transfer, then a number of different rotors that change that letter into another letter and then an input that changes the frequency with which the Rotor shift. All those different elements combined mean that one quickly get millions and then hundreds of millions of different possible outcomes.
The code was generated from the sentence 'German is a beautiful language'and ended up with over 52 Billion different combinations on letters that needed decrypting. which AI did in 12 minutes and 50 seconds.
Unlike the traditional method of cracking the code, AI was trained to look for German language and then work out the statistical probability of the sentence decrypted being the accurate original based on how 'German' it was, using 2000 cloud servers to do the calculations. Data scientists are of the view how same probability analysis can be used to detect cancer, decide if some one should get a loan or if one wants to crack the passwords.
What's really interesting is that AI is able to not only complete tasks given but also independently decide on its own parameters to search for valuable information.

Qualities Of A Good Prime Minister

By
Following are ten qualities (not in order of importance), which I believe are the most important for a Prime Minister and why ? - 1) Ability to connect with constituents - All great leaders in history had a penchant for being able to connect with their citizens i.e. a strong or habitual liking for something or tendency to do something. Leaders who have failed have probably failed in this domain. 2) Clarity of vision - The Prime Minister who knows their vision and can successfully articulate it to the voting public is one who will be held in high regard. 3) Coherent grasp of domestic issues - There has to be a keen desire and understanding of domestic concerns that directly impact the citizens. Failure to understand and address these issues will create a gap between what the Leader does and how it impacts their citizens. 4) Clear understanding of different cultures in their Governance - All good leaders will be able to understand the Political culture, Ethical/ Racial cultures, Cl

IMF suggestions for India Growth Rate

By
India's growth accelerated to 7.7.% in 4th quarter of 2017-18 (F.Y.) which was up from 7% in the previous quarter. In order to sustain the high growth rate, following three steps are suggested for India by IMF ( International Monetary Fund) to follow :- 1) To revive a Bank credit and enhance the credit provision by accelerating clean up of Bank and     Corporate Balance sheets & enhancing the growth of Public Sector Banks. 2) To continue fiscal consolidation and to lower elevated public Debt levels by simplifying &     streamlining the Goods and Service Tax (GST ) structure. 3) To renew impetus to reforms of key markets over the medium term, for example, Labor and     Land as well as improving the business climate to improving competitiveness and maintaining     the level of growth in India.  India's Gross Domestic Product (GDP) is poised to grow by 7.3.% in 2018-19 and 7.5% in 2019-20  on strengthening of Investment and private consumption.  Govt. is stead

Working Of Nuclear Plant and Generation Of Energy

By
Nuclear energy originates from splitting of Uranium atoms- a process called fission. This generates heat to produce steam, which is used by Turbine generator to generate electricity, because Nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions. It is the safe, clean, cost effective alternative contrary to claims by opponents of nuclear energy. Nuclear power reactors use controlled nuclear fission in a chain reaction. With the use of neutron absorbers, the rate of reaction controlled, so the power depends on demand. By reliably providing power 24 hours a day, Nuclear energy is an important part of the energy mix necessary to meet electricity demand. And, with no carbon emissions, it will remain an important clean energy resource for the future. For more than forty years, Duke Energy, USA has operated nuclear plants- setting industry benchmarks for safety and efficiency in the process. Working of a Nuclear Plant - A Nuclear power plant works much like a

Artificial Intelligence on Business Forecasting

By
The business world today is driven by customer demand. Unfortunately, the demand patterns vary considerably from time to time. That is why it can be so challenging to develop accurate forecasts. The goals of forecasting are to reduce uncertainty & provide benchmarks for monitoring actual performance. A new generation of Artificial Intelligence technologies have emerged that hold significant commitment on improving forecasting process including applications as product demand, employee turnover, cash flow, distribution requirements, manpower forecasting & inventory. Artificial Intelligence systems are designed to bridge the gap between the two traditional forecasting approaches - Managerial and Quantitative. Artificial Intelligence is defined as a Computer Based analytical process exhibiting actions and behavior considered ' Intelligent' by human observers. A.I. attempts to mimic human thought process including reasoning and optimization. One purpose of A.I. is

FDI - Foreign Direct Investment- Types And Essentials

By
FDI started in India in 1991 in wake of economic crisis and since then it has steadily increased. It is an investment made by an individual or firm in one country into business interest located in another country. Besides being a critical driver of economic growth, FDI is a major source of Non-Debt financial resource for the Economic Development of India. Foreign companies invest in India to take advantage of relatively lower wages, special investment privileges (Tax exemptions) etc for a country where foreign investments are being made. It also means achieving technical know-how and generating employment. The India Govt's favorable policy regime and robust business environment have ensured that foreign capital keeps flowing into the country to improve in view of ease of doing business and relaxation in FDI norms is yielding results. FDI equity inflows in India was US $44.37 billion in 2018-19 mainly on account of Service Sector, Computer hardware and software, Trading, Telecomm

Satellite Prediction Of Floods In India

By
Floods are one of the most devastating and costly national disasters each year affecting on an average 96.9 million people worldwide and causing $13.7 Billion in damages according to U.N. Office for Disaster Risk Reduction. They wash away or destroy Homes, Pollute Drinking Water and a source to giving birth to water borne diseases. The Indian sub-continent is one of the most affected due to chronic flood events mostly induced by periodic monsoon rainfall. The North - Eastern state of Assam has a complex fluvial systems of rivers, mainly with two inter connected rivers of Brahmaputra and Barak which together enter Bay of Bengal. Due to enormous sediment transport from the upper catchment areas and subsequent lack of carrying capacity of the channels in these two river valleys, flooding is a periodic phenomenon every year during the peak monsoon months from June to Sept. causing extensive damages to life and property. Satellite plays important role in detection and monitoring of flo

Tools To Measure Economic Progress Of A Country

By
Economic growth is the increase in the Inflation- adjusted market value of Goods and Services produced by an economy over time. It is conventionally measured as the percentage of increase in Real Gross Domestic Product (GDP). Economic reports and indicators provide measurements for evaluating health of our economy, latest business cycles and how customers are spending and generally faring. Given below are Nine points common and vital economic indicators for experts to judge and draw opinions from: 1) M2 (Money Supply) - Does not include Institutional Money Fund Assets, large denominated Time Deposits or Special Reserves Banks required to make. Data released by Reserve Federal System is used to assess current economic and financial conditions and to help alter its Monetary Policy which includes raising and lower interest rates. 2) Real GDP (Gross Domestic Product) -  Real GDP is a comprehensive way to gauge the health and well-being of an economy.It is the market value of all goods

US Dollar - Effects in the modern economy

By
U.S. dollar is strongest currency which supports U.S. economy. The reason is that more than one -third countries of the world's gross domestic product comes from countries that peg their currencies to dollars. A strong economy will attract investment from all over the world due to perceived safety and ability to achieve return on investment. Since investors seek higher yield on investment particularly from abroad, creates a strong capital account and high demand for dollars. Economic losses of World War have resulted into destruction of capital, trade, human suffering, spread of diseases, displacement of people and destruction of environment among others. Bretton Woods system In the post war scenario, need was felt to have a system to control value of money between different countries. It means that each country had to have a monetary policy that kept exchange rate of its currency within a fixed value - plus or minus one percent - in terms of Gold.This system was agreed upon

Economy of UAE

By
UAE consists of seven Emirates founded and declared their independence from Britain on 2nd December, 1971 as a federation. Six of the emirates, i.e. Abu Dhabi, Dubai, Sharjah, Ajman, Fujairah & Umm Al Quwain combined on that date. Ras Al Khaimah joined on 10th February, 1972. The total population of seven emirates is 8.3 million ( 38% live in Abu Dhabi, 30% in Dubai, rest in other  areas of Emirates). UAE has never been a British colony but have come under British protection. For centuries, region was involved in rival ties between local Emirs on Land and Pirates on sea. Britain began attacking pirates to protect its trade with India. This led to ties with the Heads of the areas which continued  till 1971 when agreement was terminated. It was due to Britain's imperial overreach exhausted politically and bankrupt financially, Britain decided to abandon thee states. UAE became member of Arab league and member of United Nations in 1971.The country is also a member of OPEC and

Devaluation and causes for Foreign Exchange rates variation

By
  Indian Rupee and Devaluation  Indian Rupee was settled at Rs.13/- per pound and dollar @ Re.1/-  in 1947 after partition. It continued up to 1966 when first devaluation took place. This was carried out since Govt, was consistently facing balance of payment deficit since 1950 and failure of Govt. efforts to revive and have positive trade balance Moreover, war with Pak in 1965 and cutting off of foreign aid by USA and other countries fueled the crisis.Rise in fuel prices all around did put pressure on inflation as well.  In 1991, second devaluation took place due to downward pressure on Indian Rupee from international markets. It was a part of Economic reforms.The restrictions were relaxed on imported capital goods. Import Export policy replaced import quotas with tariffs causing major overhaul of trade policy Devaluation is undertaken as a means of correcting deficit in balance of payments.        Foreign Exchange variations and causes Foreign Exchange is one of the most impo
