U.S. election procedure...for those who think Obama has won the election !!

Posted by Unknown on Oct 31, 2008

TYPES OF ELECTION:

  1. A primary election is a nominating election in which the field of candidates who will run in the general election is chosen. Victory in a primary usually results in a candidate being nominated or endorsed by a political party for the general election.
Barrack Obama won the primary election among Democrats.
John McCaine won the primary among Republicans.

**For those of you who thought Obama won the U.S. election, the real action hasn't even
started.**
  1. A general election is an election held to choose among candidates nominated in a primary (or by convention, caucus or petition) for federal, state and/or local office. The purpose of a general election is to make a final choice among the various candidates who have been nominated by parties or who are running as independents (not affiliated with a major political party) or, in some cases, write-in candidates. Measures such as proposed legislation (referendums), bond issues (approving the borrowing of money for public projects) and other mandates on government also can be placed on the ballot.
  2. In addition, many states provide for special elections, which can be called at any time, to serve a specific purpose, such as filling an unexpected vacancy in an elected office.

What is a convention?

Conventions are meetings sponsored by political parties for members of the party to discuss issues, candidates and campaign strategies. These meetings can last several days.In presidential elections, after state primaries are concluded, each party holds a national convention to formally select the presidential nominee – usually the candidate who secured the support of the most convention delegates, based on victories in primary elections. Typically, the presidential nominee then chooses a running mate to be the party's candidate for vice president.

The Democratic National Convention will be in Denver on August 25-28, 2008.
The Republican National Convention will be in St. Paul, Minnesota, September 1-4, 2008.


What is a caucus?

A caucus is a meeting at the local level in which registered members of a political party in a city, town or county gather to express support for a candidate. For statewide or national offices, those recommendations are combined to determine the state party nominee. Caucuses, unlike conventions, involve many separate meetings held simultaneously at multiple locations. Both the Democratic and Republican parties have their own rules governing caucuses. Those rules vary from state to state.


SCHEDULING ELECTIONS

When are general elections held?

They are held on the first Tuesday after the first Monday of November. The 2008 general election will be held on November 4.

ELECTORAL COLLEGE

What is the Electoral College?

The Electoral College is the group of citizens designated by the states to cast votes for the president and vice president on behalf of state citizens. The process for selecting electors varies from state to state, but usually the political parties nominate electors at state party conventions or by a vote of the party's central committee. The voters in each state, by casting votes for president and vice president, choose the electors on the day of the general election. The Electoral College, not the popular vote, elects the president, but the two votes are tied closely.

How does the Electoral College elect the president?

The Electoral College system gives each state the same number of electoral votes as it has members of Congress. The District of Columbia is allocated 3 electoral votes. There are a total of 538 votes in the Electoral College; a candidate for president must get 270 to win (a simple majority). All but two states have a winner-take-all system, in which the candidate who gets the most popular votes in the state is allocated all of the state's electoral votes.

Let me explain....

popular votes...the vote count of citizens of the state.

electoral votes...no. of representatives from that state in congress...District of Columbia has 3

Now, the candidate winning more popular votes is awarded all the electoral votes of that state i.e. whoever gets more popular votes in D.C. is awarded 3 votes.

All over the country there are 538 electoral votes and 270 are needed for simple majority.

If no presidential candidate wins a majority of electoral votes, the 12th Amendment to the Constitution provides for the presidential election to be decided by the House of Representatives. In such situations, the House selects the president by majority vote, choosing from the three candidates who received the greatest number of electoral votes. Each state would cast one vote.

GSM vs CDMA

Posted by Unknown on Oct 30, 2008

GSM

Advantages of 2G GSM


* GSM has more stable network with robust features.
* Less signal deterioration inside buildings.
* Ability to use repeaters.
* Higher talktime in GSM phones due to the pulse nature of transmission.
* The availability of Subscriber Identity Modules (SIM) allows users to switch networks
and handsets.
* GSM covers virtually all parts of the world so international roaming is not a problem.
* Much bigger number of subscribers globally creates a better network effect for GSM
handset makers, carriers and end users.

Disadvantages of 2G GSM

* Pulse nature of TDMA transmission used in 2G interferes with some electronics, especially
certain audio amplifiers. 3G uses W-CDMA now.
* Intellectual property is concentrated among a few industry participants, creating barriers to
entry for new entrants and limiting competition among phone manufacturers.
* GSM has a fixed maximum cell site range of 35 km, which is imposed by technical limitations

CDMA

Advantages of CDMA

* Capacity is CDMA's biggest asset; it can accommodate more users per MHz of bandwidth
than any other technology.
* Has no built-in limit to the number of concurrent users.
* Uses precise clocks that do not limit the distance a tower can cover.
* Consumes less power and covers large areas so cell size in CDMA is larger.
* Able to produce a reasonable call with lower signal (cell phone reception) levels.
* Uses soft handoff, reducing the likelihood of dropped calls.
* CDMA's variable rate voice coders reduce the rate being transmitted when speaker is not
talking, which allows the channel to be packed more efficiently.
* Has a well-defined path to higher data rates.

Disadvantages of CDMA

* Most technologies are patented and must be licensed.
* Breathing of base stations, where coverage area shrinks under load. As the number of
subscribers using a particular site goes up, the range of that site goes down.
* Because CDMA towers interfere with each other, they are normally installed on much
shorter towers. Because of this, IS-95 may not perform well in hilly terrain.
* CDMA covers a smaller portion of the world, and CDMA phones are generally unable to
roam internationally.
* Manufacturers are often hesitant to release CDMA devices due to the smaller market, so
features are sometimes late in coming to CDMA devices.
* Even barring subsidy locks, CDMA phones are linked by ESN to a specific network, thus
phones are typically not portable across providers.

CDMA....alternative to GSM

  • Interim Standard 95 (IS-95), is the first CDMA-based digital cellular standard pioneered by Qualcomm. The brand name for IS-95 is cdmaOne.
  • CDMA or "code division multiple access" is a digital radio system that transmits streams of bits (PN Sequences). On the other hand GSM uses TDMA "time division multiple access"
  • CDMA permits several radios to share the same frequencies. Unlike TDMA "time division multiple access", a competing system used in 2G GSM, all radios can be active all the time, because network capacity does not directly limit the number of active radios.
  • Since larger numbers of phones can be served by smaller numbers of cell-sites, CDMA-based standards have a significant economic advantage over TDMA-based standards, or the oldest cellular standards that used frequency-division multiplexing.
