Science : A Blessing Or A Curse

The way another contrivance is utilized makes it great or awful. The same is the situation with Science. Science plays an exceptionally essential and suitable part in our life and might be a companion or an adversary as per the way it is utilized.

A significant part of the advancement that humankind has made in diverse fields right from the Stone Age to the Up to date Age is because of the advancement made in the field of Science. Not just material advancement and yet the mental viewpoint of man has been impacted by it. It has made man's life more satisfied and more agreeable.

Science is at the foundation of all advancement. It tries to demonstrate the standards behind common phenomena, and researchers for long have been saddling this information for the profit of the social order all in all. The provision of exploratory looks into has ended up being a favoring in a bigger number of routes than one, on the grounds that we have procured compensates in essentially all fields of life. Extraordinary strokes of genius of researchers have made the on the whole living less demanding and more agreeable.

Agribusiness, business, transport, correspondence and drug, to name yet a couple of, are everything exceptionally obliged to the marvels Science has handled. Today, the planet has experienced a gigantic change due to the quick strides made by Science and Engineering. Therapeutic Science has made incredible strides and today, we can trust for a longer and healthier life. New novelties and revelations have not just assisted in killing feared illnesses like smallpox, T.b., yellow fever, and so on., from the substance of the earth, and yet expanded future of people.

Science has been utilized quite viably as a part of enhancing agrarian preparation. The nourishment generation levels and quality have enhanced by various elements for example soil examination, half breed mixtures of products giving higher yield, fertilisers, pesticides, propelled instruments and apparatus, and so forth. Today, we have scores of meteorological satellites in space sending information, pictures to earth stations assisting horticulture researchers find and examine soil designs and in this way increment crop yield.

Power is one of the most fantastic considers of present day Science. It has gotten revolutionary updates the way individuals used to exist. In addition, the revelation and improvement of countless sources—coal, petroleum, regular gas, power, and so forth., have empowered mankind to prevail over the boundaries of nature. This stuff has expedited the development of quick modes of transport and correspondence, which in transform has updated the planet into a worldwide village.

My Best Friend - my companion for life!

There is an idea that fellowship and individuality are the two dichotomous states, correspondingly inseparable constituents of human life. Added to it is the indisputable reality that the person who finds constructive and sincere companion is around the exact few lucky ones. All delights, compensates and riches are momentary and temporary when put to test in a rivalry with the unceasing and eminent jollity.

The cheer, rapture and blessedness of the everlasting bond of accurate kinship, is contemporaneously describable as odd and inseparable. Contrasted with companionship, gold is earth. William Program once put this ethereal feeling into his statements. How uncommon is that blaze of minute when we acknowledge we have revealed a companion. Without a doubt, without a particle of mistrust, developing correct and extraordinary kinship in life (that finally withstands even the hardest and the most antagonistic test of time) increases the exceptional and partitions the disasters.

Without companions, it is like life on a forsook island. As one logician composed numerous hundreds of years back, There is nothing on the planet more significant than companionship. Those who oust it from their lives uproot sort of the sun from the earth, due to all natures endowments, it is the most lovely and the most satisfying. To discover a legitimate companion in a lifetime is favorable luck; to keep him is a favoring. To my psyche, Robin Sharma puts it all the more apropos and suitably, An individual with three incredible companions is a rich individual in fact.

On the other hand so far as that is concerned, recognize the renowned worldwide axiom of Samuel Johnson, Accurate delight comprises not in the incomprehensible number of companions, yet in their worth and decision. It is, on the other hand, a matter of sheer incident that I have three companions, whom I expect so dear to remember my heart that statements might everlastingly remain lacking to depict their essentialness in my life. An accurate companion is like a four-leaf clover: difficult to find however fortunate to have. Aristotle resplendent statements go like this Kinship is a solitary soul residence in two bodies. And rightly in this way, my soul or my life, abides in the aforementioned three companions of mine.

Is China a threat, or we just overthinking?

Recently, in wake of a border dispute, the Sino-Indian relationships are again under scanner. These two powerful neighbors of Asia always have had a checkered relationship. Both countries are equipped with nuclear weapons, have large and well-equipped armies at their behests and, except one major conflict in the 1960s, there had been no major untoward events to report. Although, there are quite a few causes of continuing disagreement, like Indian discontent on Chinese support to Pakistan, or Chinese discontent on India’s role in the South China Sea, yet, overall the relationship parameters have been ‘balanced’.

The general understandings between these two militarily powerful nations of Asia are peaceful and aimed at promoting an environment of mutual financial and strategic ties. The financial equation deserves special mention. The two countries facilitated $66.4 billion worth of trade in 2012. Recently a mutual agreement was signed between the responsible authorities of the two countries, aiming at a momentous $100 billion trade by 2015. India and China are also two of the important members of the new financial coalition, BRICS.
Let us have a look at the reasons why China ‘may’ possess a threat. The main issue with China is its abruptness and unpredictability of actions. Take the current border dispute for example.

Suddenly the Indian side discovers Chinese troops claiming their position, ‘apparently’ in the Indian side of the border! Chinese officials insist that there has been no trespassing and Indian officers confirm that the region where the ‘trespassing and settling soldier camps’ is a disputed region. Does the presence of a disputed region mean Chinese troops can occupy and set up camps in the region? When it is disputed, it should not belong to either country! The Chinese logic apparently seems, “let India think it is disputed, we know that this land belongs to us.”

Diplomats are busy finding the answer, whereas, both countries have thought it befit to put their respective armies on high alert and strengthen the forces at the controversial Depsang area in the Western Sector of the Sino-Indian boundary. The Chinese action was abrupt, but well planned, and still now no signs show that the Chinese army intends to budge from their camps. In case, China refuses to retreat, India’s possible alternatives remains unclear. We can only guess at the high voltage diplomatic drama within the corridors of the Indian Government and the Chinese Government. 
 
The CCP governs the Chinese democracy with an iron hand, which is evident from the heavy censoring and regulation of internet in China. Even in this age of information, China completely controls the information flow to the world via the internet. Criticisms of Government policies online are under strict limits imposed by the CCP, and any violations are met with severity. China passed a law in 2007 that bans Tibetan Buddhist monks from reincarnation! China’s obsession with territory acquisition can be surmised from the fact that lakhs of Tibetans received refuge in India and other parts of the world when China ascertained control over Tibet. Many Tibetan monks have since given life by self-immolation, without having any effect on China’s policy over Tibet. (In fact, the fact that India houses the Tibetan exile Government at Dharamshala, may be one of the ulterior motives behind Chinese aggression.) These references go on to imply that the Chinese government is a very strict one, and Indian diplomats would find it tough to come in terms with Chinese aggression, and work out a solution.

China is not yet a ‘threat’ ‘per se’, but possesses the willingness and the potential to be one.

Indian Government- White Paper has grey areas !!

The government’s White Paper on black money falls far short of desires in so far as it has none of these revealed any names of foreign account holders, nor has it thought of an assessment of the measure of slush subsidizes stashed away in foreign banks.

Actually it has headed off to the degree of playing down the hazard of black money by handing out statistics to show that the cash held by Indians in secret Swiss Bank accounts has came down sharply. This was just to be needed, as the government's tardy action is certain to have given account holders enough chance to shift base.

All things considered, the White Paper has incorporated undermining in its ambit and proposed more stringent punishment for tax and duty evaders and those convicted under the Prevention of Corruption Act which is a welcome suggestion.

Then again, the paper has left numerous grey areas, for example its proposal to permit amnesty from prosecution to those who are ready to carry their cash from tax havens. While it states that this might be an one-time alternative, it too raises the issues of the ethical risk and open sentiment this might involve, in this manner winding up unable to take a positive stand on the subject.

This will help the students "One nation one test"

The Indian Institutes of Technology ( IITs) have their path in the change "one nation one test" proposal for the Joint Entrance Examination( JEE) for engineering colleges, the bargain equation has the benefit of diminishing the numerous tests that a hefty number of learners went up against in attempting to get a desired seat in a engineering college. The truly major grow from the new system is the weightage that will be given to the Class XII Board examination.

This will go far in diminishing the impact of the pack schools that "prepare" scholars to break the JEE and guarantee that people don't overlook the essentialness of the school leaving examinations, as numerous have in reality, been doing lately. The IITs have devised a workable plan to get their route in demanding that they will select their participants through their particular technique. Now, they have stated that they might be ready to recognize gripping the accurate "one nation one test' equation in the event that it works well by 2015.

Minimum Number of State Variables - control systems

The order of the differential equation describing the system is equal to the minimum number required. The three simultaneous first-order differential equations are required along with three state variables, if the third order third-order differential equation describes the system. The order of the differential equation is the order of the denominator of the transfer function after canceling the common factors in the numerator and denominator, from the perspective of the transfer function.

In most of the cases, to determine the number of state variables through another way is to count the number of independent energy-storage elements in the system. the order of the differential equation and the number of state variables is equal to the number of these energy-storage elements.

In many cases it is also possible to complete the writing of the state equations, as the derivatives of the state variables cannot be expressed as the linear combinations of the reduced number of state variables. Even if we select the minimum number of state variables, it will not be linear independent, so we will be not able to solve all the other system variables. In addition, the worst part of it will be that we will not be able to complete the writing of the state equations. Often there are more than the than the minimum number of state variables are included in the state vector then the requirement.

Here, the two possible cases exist. Often the state variables are chosen to be the Physical variables of a system; such as position and velocity in the mechanical system. The possibility of these cases to be arising is where these variables although linearly independent are decoupled. In order to solve for any of the other linearly independent variables or any other dependent system variable, some linearly independent variables are not required. In the case of the mass and viscous damper whose differential equation is M dv/dt + Dv = f(t), and where v is the velocity of the mass. One state equation   is required to define this system in the state space with velocity as the state variable, as it is a first order equation. In addition, as there is only one energy-storage element, mass, there is a requirement of only one state variable to represent this system in state space. However, the mass has an associated position, which is linearly independent of velocity.
In order to include the position in the state vector along with the velocity, we just have to add the position as a state variable that is linearly independent of the other state variable, velocity. In the Figure 3.4 it has been illustrated fully what is happening.

The first block is the transfer function which is equivalent to M dv{t) / dt + Dv(t) = f(t) whereas the second block shows that we integrate the output velocity to yield the output displacement. Therefore, for the displacement as an output, the denominator, or characteristic equation, has to be increased in order to 2, the product of the two transfer functions. Many times, by including additional state variables, the writing of the state equations is simplified.

In another case, when the added variable is not linearly independent of the other members of the state vector, the size of the state vector arises. This event is resulted when the variable is selected as a state variable but in addition, its dependence on the other state variable is not immediately apparent.
For an example, in order to select the state variables the energy-storage elements may be used and it may be hard to recognize the dependence of the variable associated with one energy-storage element on the variables of other energy storage elements. Therefore, the system matrix’s dimension is unnecessarily increased and the solution for the state vector is more difficult.

Now, we find the state-space representation for a mechanical system. It is more convenient for us to work with the mechanical systems in order to obtain the state equations directly from the equations of motion rather than from the energy storage elements. For an example, consider an energy-storage element such as a spring, where F = Kx. The derivative of a physical variable as in the case of electrical networks, where i = C dv/dt for capacitors, and v = L di/dt for inductors is not included in this relationship. Therefore, in the mechanical system, we change our selection of the state variables to be the position and velocity of each point of the linearly independent motion.

In this example, there are three energy storage elements and there will be four state variables too. An additional linearly independent state variable is also included for the convenience of writing the state equations.  It is left on the students to show how the system yields a fourth-order transfer function, if we relate the displacement of either mass to the applied force, and a third-order transfer function if we relate the velocity of either mass to the applied force.

Brace for safer roads in India with speed limiting devices!

With the ongoing activities police and speed cameras are unable to check the extreme tendencies of Indian drivers, the powers have now turned to another result: speed-limiting devices. The GPS-based technology, which might be incorporated in the autos by the makers, would automatically avert a car from breaking speed limit points by slicing fuel to the motor.

Any endeavors to tamper the device might trigger a 'default mode' compelling the vehicle to run at frustratingly moderate speeds. The road transport and interstate ministry has been testing the device, granted that it will need freedom from the law ministry after the proposal might be brought about.

With statistics demonstrating that India has the most deaths because of vehicular collisions globally, it appears reasonable to make the most of existing innovation to handle this issue. Acknowledging the hazard of over-speeding averts one third of all mishap deaths —and the way that neglectful drivers imperil not just themselves yet everyone else around —an innovation such as this could wind up significantly upgrading the security of our roads.
