PSLV-C16 successfully launches Resourcesat-2 into orbit

India's PSLV-C16 rocket on April 20 ,2011, successfully launched into orbit the latest remote sensing satellite Resourcesat-2 that would study and help manage natural resources along with two nano satellites.

ISRO's homegrown workhorse Polar Satellite Launch Vehicle placed in a 'Polar Sun Synchronous Orbit' Resourcesat-2, Youthsat and X-Sat about 18 minutes after it blasted off from the Satish Dhawan Space Centre launch pad here, 90 km from Chennai, at 10.12 am.

"PSLV-C16 Resourcesat-2 mission is successful," a jubilant Indian Space Research Organisation Chairman K Radhakrishnan announced shortly after all the three satellites were hurled into space one after another 822 km above earth in a text book launch.

The ISRO chief's announcement was cheered by the battery of scientists at the mission control centre who heaved a sigh of relief as they were gripped by an added anxiety following two successive failures of GSLV missions last year.

ISRO`s workhorse PSLV has an impressive track record of 16 successful missions out of 17 attempts and has launched 44 satellites, including 25 payloads from abroad, since 1994. The launch vehicle will place in polar sun synchronous orbit the 1206-kg Resourcesat-2, 92-kg Youthsat and 106-kg X-sat satellites 822 km above Earth.

 

The mission``s primary satellite, ISRO built Resourcesat-2, is an advanced remote sensing spacecraft to facilitate study and management of natural resources. It will replace Resourcesat-1 launched in 2003 and provide data with enhanced multi-spectral and spatial coverage on natural resources.

 

10 things to know about Anna Hazare and Lok Pal Bill

Let's at least pass the Message on and enlighten ppl on what is the Importance of this Anna Hazare's Hunger Strike….. !!!!!!!!!

1. Who is Anna Hazare?

An ex-army man. Fought 1965 Indo-Pak War

 

2. What's so special about him?

He built a village Ralegaon Siddhi in Ahamad Nagar district, Maharashtra

 

3. So what?

This village is a self-sustained model village. Energy is produced in the village itself from solar power, biofuel and wind mills.

In 1975, it used to be a poverty clad village. Now it is one of the richest village in India. It has become a model for self-sustained, eco-friendly & harmonic village. 

 

4. Ok,...?

This guy, Anna Hazare was awarded Padma Bhushan and is a known figure for his social activities.

 

5. Really, what is he fighting for?

He is supporting a cause, the amendment of a law to curb corruption in India.

 

6. How that can be possible?

He is advocating for a Bil, The Lok Pal Bill (The Citizen Ombudsman Bill), that will form an autonomous authority who will make politicians (ministers), beurocrats (IAS/IPS) accountable for their deeds.

 

8. It's an entirely new thing right..?

In 1972, the bill was proposed by then Law minister Mr. Shanti Bhushan. Since then it has been neglected by the politicians and some are trying to change the bill to suit thier theft (corruption).

 

7. Oh.. He is going on a hunger strike for that whole thing of passing a Bill ! How can that be possible in such a short span of time?

The first thing he is asking for is: the government should come forward and announce that the bill is going to be passed.

Next, they make a joint committee to DRAFT the LOK PAL BILL. 50% goverment participation and 50% public participation. Because you cant trust the government entirely for making such a bill which does not suit them.

 

8. Fine, What will happen when this bill is passed?

A LokPal will be appointed at the centre. He will have an autonomous charge, say like the Election Commission of India. In each and every state, Lokayukta will be appointed. The job is to bring all alleged party to trial in case of corruptions within 1 year. Within 2 years, the guilty will be punished. Not like, Bofors scam or Bhopal Gas Tragedy case, that has been going for last 25 years without any result.

 

9. Is he alone? Whoelse is there in the fight with Anna Hazare?

Baba Ramdev, Ex. IPS Kiran Bedi, Social Activist Swami Agnivesh, RTI activist Arvind Kejriwal and many more.

Prominent personalities like Aamir Khan is supporting his cause.

 

10. Ok, got it. What can I do?

At least we can spread the message. How?

Putting status message, links, video, changing profile pics.

 

At least we can support Anna Hazare and the cause for uprooting corruption from India. 

At least we can hope that his Hunger Strike does not go in vain.

At least we can pray for his good health.

The Muller C-element

The Muller C-element, or Muller C-gate, is a commonly used asynchronous logic component originally designed by David E. Muller. It applies logical operations on the inputs and has hysteresis. The output of the C-element reflects the inputs when the states of all inputs match. The output then remains in this state until the inputs all transition to the other state. This model can be extended to the Asymmetric C-element where some inputs only effect the operation in one of the transitions (positive or negative). The figure shows the gate-level and transistor-level implementations and symbol of the C-element.

To understand how this works, look at the transistor-level implementation more closely:

The C-element stores its previous state with two cross-coupled inverters, similar to an SRAM cell. One of the inverters is weaker than the rest of the circuit, so it can be overpowered by the pull-up and pull-down networks.

If both inputs are 0, then the pull-up network changes the latch's state, and the C-element outputs a 0. If both inputs are 1, then the pull-down network changes the latch's state, making the C-element output a 1. Otherwise, the input of the latch is not connected to either V_dd or ground, and so the weak inverter (drawn smaller in the diagram) dominates and the latch outputs its previous state.

The Muller C-element was first used in the arithmetic logic unit (ALU) of the ILLIAC II supercomputer, proposed in 1958, and operational in 1962.
