Just wanna try.. :D

This is the circuit I'm going to build,
From a main oscillator of frequency (f_m), a frequency divider (IC1A) supplies values of f_m/2, f_m/8, and f_m/16. Acceptable values of f_m depend on the selected CMOS technology. The circuit has been tested at f_m = 2 MHz with basic CMOS logic, and at 20 MHz with HCMOS.

Dibits are formed from a digital input (PCM signal) in shift register IC2B, and in the dual flip-flop IC3. The different phases of 0º, 90º, 180º, and 270º are produced at outputs QA, QB, QC, and QD of the four-bit shift register, IC2A.

Finally, the dibits (on pins A and B of IC4) control the multiplexer (data selector) output. This is a selected phase from D0, D1, D2, or D3, according to the dibit combinations. The rest of the circuit is a simple band-pass filter that eliminates dc levels and shapes the pulse, plus an amplifier to set the desired output level. The QPSK output frequency is f_m/8.

New Topic

My research topic about WiMAX now has changed because of something. And now I'm trying to start my new research about Power Line Communication.
This technology isn't a new technology, but it's been founded by 1920. But for that time, the communication only for KWh meter or other measurement tools. And for now this technology has been used to connect computers to worldwide web.
At this research I'll make my own modem, with my research group I'm trying to implement a telephone using power line cables.

Lapindo Mud Crisis

2007-06-20T01:02:00.000-07:00

Java island especially East Java are sinking because of Lapindo Brantas mud crisis. For more than 10 months mud has flowed from an exploratory well near Porong, inundating 25 square kilometers, putting more than 1000 people in hospital with breathing difficulties and forcing more than 10,000 from their homes. It has cut roads, covered train lines and threatens the rail link between Jakarta and Surabaya, Indonesia's busiest port.

A police investigation has found seven Lapindo employees were suspected of criminal negligence over the drilling. An emergency cabinet meeting on Thursday night decided that all measures must be taken to protect and compensate people living in the area, safeguard basic infrastructure, preserve East Java's economy and lessen the environmental damage. Lapindo should meet all expenses, cabinet ordered.
The Geological research until now still doesn't know how to stop the mud, one way has done that is to put big balls that linked each other to the hole but it's failed to stop and even the flow debit become more and more every day. For this case, the team of research told the flow will stop normally for 30 years, but at the time the mud stop flowing the East Java Province will full of mud.
Yesterday the new flow that contain water and sands occurs not far from the main flow, and until today none has been done to stop this although the flow has reach 7 meters from the ground or it has reached 500% bigger than first time the flow found.

Love?

2007-05-11T21:23:00.000-07:00

Love bade me welcome: yet my soul drew back,
Guilty of dust and sin.
But quick-eyed Love, observing me grow slack
From my first entrance in,
Drew nearer to me, sweetly questioning
If I lacked anything.

"A guest," I answered, "worthy to be here":
Love said, "You shall be he."
"I, the unkind, ungrateful? Ah, my dear,
I cannot look on thee."
Love took my hand, and smiling did reply,
"Who made the eyes but I?"

"Truth, Lord; but I have marred them; let my shame
Go where it doth deserve."
"And know you not," says Love, "who bore the blame?"
"My dear, then I will serve."
"You must sit down," says Love, "and taste my meat."
So I did sit and eat.

Microprocessor

2007-04-17T19:03:00.000-07:00

One of my interest at computer technology is microprocessor development. This is also my practicum subject at University of Indonesia. As an assistant at the Lab, I must improve my knowledge about microprocessor especially Intel, Zilog, and Motorola.

Basically every microprocessor has a sub-processor like ALU (Arithmetic Logic Units), control unit, registers, and this sub-processor become more and more as this technology always improves time by time. Registers is a part that the data will be proceed, this part also known as an internal memory of microprocessor. At Intel microprocessor there is 4 kind of this registers; one is general purpose registers, stack registers, flag registers, and index registers. All of this registers has it's own specific function.

General purpose registers is some registers for general use. This register usually has it's own function such as AX is a accumulator register, BX is a Base register (used as a base address of a memory), CX is a count register (used as a counter for loop processes), DX is a data register (used as a MSB for multiply and divide processes).

Flag registers is some registers to provide the status of environment that the program executes. this register is not for storing data that will be proceed, but this register contains the status of the CPU real time. Parity, overflow, carry, auxiliary carry, etc is some of this registers

Index registers used to store the address of string data that stored on the memory. SI (Source Index contain the source address of the string data) and DI (Destination Index contain the destination address of the string data) are two kinds of this register.

Stack registers used to store data with LIFO (Last In First Out) algorithm.

WiMAX as my research..

2007-04-16T22:59:00.000-07:00

This is my research about WiMAX.. a technology standard issued by IEEE 802.16

WiMAX (Worldwide Interoperability Microwave Access) is a wireless networking system based on the IEEE 802.16 standards family. The version 802.16-2004, published in October 2004, supports various kinds of network topology. One of topology is called PMP (Point-To-Multipoint).

Within this topology every Mobile Station (MS) communicate directly via Base Station (BS). The second topology is denoted MESH. In this mode, two MSs communicate without employment of BS. The 802.16-2004 does not support handovers between cells. Consequently, 802.16-2004 allows only a fixed or nomadic access. Handover procedures are implemented in newest version of 802.16e,standardized in September of 2005. This version specifies handovers for portability and simple or full mobility of users.

WiMAX uses OFDM for it's modulation which is known as the best modulation method for a wireless access networking, but it's very complicated, so it is my problem to continue my research. I'm stuck here!

My point is to know about QoS of this WiMAX and try to simulate the system with software MATLAB 7.0.4 (simulink).

Special for womens....

To get beautiful lip, say kindly to every word.

To get beautiful eye, look for kindliness to every one you meet.

To get beautiful shape of the body, give your food to them which was starvation.

To get beautiful hairs, ask a child to comb it with the finger everyday.

To get beautiful body language, walk with knowledge, and never be alone.

Human beings, is far from all other creation. Need to change, to be innovated, to be re-formed, and to be forgiven. Thus, don’t minimize the people of you heart. If you have ever done it before, remember always. If one time you need help, there will be hand for you. And with your increase of your age, you will progressively thank goodness have given two hands, one to help your own self and the other one to help others.

Women’s beauty is not lays to their clothes, not to theirs body shape, or the way she comb the hairs. Women’s beauty are on their eyes, how she look at the world. Because at their eyes are laid gates to everyone’s heart, where love can expand.

Women’s beauty is not at the softness of the face. But lays on the pure beauty that shines at her soul which give love and attention. And that beauty will grow all the time.

For choco lovers.....

An investigation is under way after Cadbury withdrew a million chocolate bars which may have been contaminated with a rare strain of salmonella.

The company says the recall - while the Food Standards Agency and the Health Protection Agency investigate - is precautionary and that the risk is low. But a bacteriologist says there is no safe level for salmonella in chocolate.The possible contamination has been traced to a leaking pipe at a Cadbury's plant in Herefordshire in January. Samples were sent to an independent laboratory after the leak was discovered at the Marlbrook plant, and the montevideo strain of salmonella was identified. Government watchdog the Health Protection Agency (HPA) confirmed the strain and, a week ago, the Food Standards Agency (FSA) was alerted.

On Monday, Cadbury officially informed the FSA of the possible contamination of the seven products. The 250g Dairy Milk Turkish, Dairy Milk Caramel and Dairy Milk Mint bars, the Dairy Milk 8 chunk and the 1kg Dairy Milk bar are among products affected. The 105g Dairy Milk Buttons Easter Egg and the Freddo bar were also affected.

'Precautionary measure'

Cadbury's European president Matthew Shattock told BBC Radio 4's Today programme the recall decision was made after the FSA revealed there had been an increase in the number of salmonella cases this year. "We decided to conduct a precautionary recall to reassure our consumers and the public at large to minimise any confusion as to the quality of our products," he said. Salmonella is a common cause of food poisoning but the montevideo strain is very rare. There have been 45 cases in the UK in the last four months, compared with just 12 in the same period last year. But a Health Protection Agency spokeswoman stressed that at the moment there was no evidence for a link between the increase in cases and the Cadbury recall.

Mr Shattock said the firm was "absolutely satisfied" its products were safe to eat. "We identified a problem early. We corrected it and fixed it," he said. Cadbury said the levels of contamination were "significantly below the standard that would be any health problem". It said people who had eaten one of the affected bars should not be worried about the risks but could contact the company for a refund. However, bacteriologist Professor Hugh Pennington of Aberdeen University told BBC News that the only safe level of salmonella in chocolate was "zero". "The fat in chocolate actually preserves the salmonella from the normal intestinal defences, so you don't have to eat very many salmonellas to get infected. "It's about a thousand times less than if you're eating it from traditional sources like meats," he said. The factory at Marlbrook generates 97,000 tonnes of milk chocolate crumb every year. It processes 180 million litres of fresh milk, 56,000 tonnes of sugar and 13,000 tonnes of cocoa liquor annually in the production process. The crumb is transported to other sites at Bournville, near Birmingham, and Somerdale, near Bristol, to be blended with cocoa butter and turned into milk chocolate. A Cadbury spokesman said the company had been manufacturing chocolate for more than 100 years and always treated public wellbeing as its "highest priority". The free helpline number for Cadbury is 0800 818181. Uneaten products should be returned to Cadbury Recall, Freepost MID20061, Birmingham B3O 2QZ, and a refund will be given.

Opinion about Israel...

2007-02-18T19:26:00.000-08:00

When we hear the word “Israel” which is marrow in our mind is war. It is true that in the few last years Israel do more attract to attack the country which is considered to be the enemy. It’s may infuriated us, or feel very sulk with the treatment of State of Israel to Moslem nations, like President of Iran, Mahmud Ahmadinejad said a comment that the Israel must vanished from the map of world. Later then after some days he expressed Israel as a tumor and has to be removed from Mid-East area.

Maybe Ahmadinejad just dream at the night. Maybe he conceives Israel that expressed the independence at 1948 will disband. Don’t know what make it to. For human being like us, this dream is fair. When a problem very bother someone mind then it will be very possible to make it to the dream. And more than that, very usual for Ahmadinejad which have though years fo anti Israel.

But above the opinion of that, Iran have never owned to have direct confrontation with Israel. During the time that happened is psywar. With Suriah, Teheran more contributing struggle of Hamas in Palestinian and of Hizbullah at Lebanon to break the enemy with give training of weapons and military. Of course destroy State of Israel doesn’t as easy as inverting palm. More than anything else, Arab nations and Moslem cannot to coalesce because of importance of each national under influence of United States, the ally of Israel.

All side must to confess, conceiving Israel lose from earth are day-dream. They are recognized very cunning resilient at the same time. Through movement of Zionism with aim to found State of Israel The Great, Jew nation can found a state which was even confessed by a number of Arab States, including Egypt and Jordania. With the declaration of Balfour in 1917, kibbutz-kibbutz – a community of agriculture of Jew citizen can rapidly grow and a little by little conquer the land of Palestinian nation. For that, Israel is not reluctant to kill civil citizen. They not afraid to battle because they sure region occupied now is promised by God according to in old testament.

For most Moslems, conflict with Israel will long forever. They trust is Israel can be defeated, doom will immediately come. People of Islam trust this matter based on the Al-Quran.

The fact is, Israel very active and mastering the international politics and delude Moslem nations thru the UN (United Nations). During the time, that biggest organization of the world have never can discontinue the Israel impact for Palestinian nation and other Arab nations.

The matter lays in United States as one of the Security Council of UN that always use veto right to every resolution which will harming Israel. Washington will always refuse every resolution which cursing or carping cruelty of military attack of Israel to Palestinian nation. Besides, composition five very inequitable for Moslem community. This fact is very ironic, remember Islam is one of the biggest religion in the world. The Moslem community do not have representatives in security council of UN.

With English, French, and Russia, besides representing religion community of Christian, American present importance Jews. While Chinese represent the religion of Buddha. Despitefully, ad for this nuclear state have veto right, a conductive privilege to refuse resolution which is not agree with the importance of the nations.

That five countries are ascertained the plan to remove veto right. So that the reformation raised by General Secretary, Kofi Annan only limited by adding regular member. If agreed, Indonesia as a biggest Moslem community country in the world have to be selected in membership remain to as Islam faction proxy and India as representative of Hindu people. Of course both this state also have to have veto right.

Strength of Israel also conquer the economic area. They control the transaction traffic for commerce and finance through World Trade Organization (WTO). World Bank, and International Monetary Fund (IMF). Practice of free trade and globalization make all Moslem states whist most is developing country and even poor state progressively depend on the west which is pro-Israel.

Very much of economic aid with loan not helping, it exactly becoming strangle. As a result, they spatially influence policy in and abroad Moslem state, including Indonesia. Thus conceive the destruction of Israel is the same to dream the world peace. For the White House, Israel share to test-drive various recent weapons product of American brand massacre d Palestinian citizen. This is the way of a very good promotion.

This condition will continue to peep out stress in Mid-East area, So Arab nations in this area remain to be grasped by the image of war that anytime can extended. And for that the kings of Arab will shelter to the US. On the contrary, the dominations of Israel trough the medias of the world will have influenced international society opinion. Pass Iraq issue is developing nuclear weapon program, the Israel success insist America which always pretend him as world police, attacking the Iraq until the president Saddam Hussein fall down at April 2003

Though that accusation have never proven. Also the colonization done by 150 thousand of American army with other army from many country have divided the association of Iraq. Now, the country have the conflict among the Syiah and Sunni. Case of the crumple the twin tower of WTC, New York at 11 September 2001 is the other evidence of Israel propaganda. ). For sensible civilian, how can a terrorist crash the plane to the building without detected by American radar.

This event trigger the enragement of President George Bush, that immediately launch the global war to the terrorism. In reality Moslem state and Moslem becoming target. Fear of Islam become more and more among the West society.

Israel succeed to make Islam as the number one enemy of the world after ending the communist era. Of course radical Islam groups will never volunteer and will continue to give resistance. Conflict will still going on along with continuing the strength of influence of Israel.
