The Power Consumption Free Essays

The power consumption for sending (or receiving) a single message in a mobile phone Abstract: We measure overall SMS, Whatapps and Wechat for the power consumption of a single message. These results are validated by overall power measurements of two other devices: the Battery Doctor and Battery Detective. We discuss the significance of the power drawn by the various length and time of texting messages, and identify the most promising areas to focus on for further improvements of power management. We will write a custom essay sample on The Power Consumption or any similar topic only for you Order Now We also analyze the energy impact of dynamic voltage and frequency scaling of the device’s application processor. Introduction: In recent years, people have a mobile phone in their hands all the day. At the same time, device functionality is increasing rapidly. In the number of applications, texting messages occupied an important part. Hence, optimal management of power consumption of devices such as SMS, WhatsApp and WeChat is critical. In this paper we attempt to answer how much of the system’s energy is consumed by sending (or receiving) a single message of the system and under what circumstances. And we will use IPhone5 as the experimental product. Furthermore, we validate the results with computing manually and the additional mobile device: Battery Doctor, Battery Detective. Material: Experimental product: IPhone5 (IOS6. 1. 2) Timer Testing Applications: Messages, WhatsApp, WeChat Measuring Application: Battery Doctor and Battery Detective Formula: 1)The time of sending each message=The time of the usage of 1% power/ Number of messages. 2) Average electricity consumption of each message ( with the Wifi usage)= 1% power of Iphone 5/ Number of messages. ) Average electricity consumption of each message ( without the Wifi usage) =(1% power of Iphone 5/ Number of messages) – (The time of sending each message x The power consumption rate of wifi function). Methodology: Device under test Experimental setup When an iPhone is not actively being used (the screen is off), the biggest power drain are the various radios: WiFi, 3G and Bluetooth. So first tip is to turn off any service you don’t need. Settings are useful in do ing so with one tap. There is some information you need to calculate before we collect the data. Therefore, after you turn off all the service that you do not use, you have to turn on the Battery Doctor and check out the battery usage of your phone and calculate how much usage if 1%power. In the case of IPhone 5, the battery usage is 1430, therefore IPhone 5 1% power= 1430/100= 14. 30 mAh. Also, you can use the Battery Doctor to check out how long you still can use on that percentage of battery. Then, according to the Doctor Battery, when IPhone 5 in 41% power, it can use 8hrs 15mins without the WiFi function. If use with the WiFi function, it can use 7hrs 13mins. Therefore, you can calculate that: The power of IPhone 5 in 41%: 14. 3mAh x 41 = 586. 3mAh The power consumption rate of IPhone 5 without the WiFi function: 586. 3 mAh/[(60 x 8 +15) x 60] = 0. 0197 mAh s-1 The power consumption rate of IPhone 5 without the WiFi function: 586. 3 mAh/[(60 x7 +13) x 60] = 0. 0226 mAh s-1 The power consumption rate of WiFi function: 0. 0226 – 0. 0197 = 0. 0029 mAh s-1 Then, you get all the basic information which you need, and you can turn off the Battery Doctor, and start to collect the data. Then, you need to let your phone natural reduce 1% power. After it you can use the timer to count time and type your message and send it out. After you use 1% of power, you can stop the timer and count how many messages did u sent and record it. Then, you need to repeat to collect those data several times. However, you also need to do it in different power percentage, to collect more data. After u collect the data of time and number of messages sending, you can use those formula to calculate the information. Software Excel, Word, Battery Doctor, Battery Detective Results We had collected the data from 3 different power level, high power (80%), general power (20-80%), and lower power ( How to cite The Power Consumption, Papers

Ask yourself what is the best invention ever? is it the internet like a lot of us have said or is it the smartphone that us teens can't seem to take our eyes off of (cough Diego) I say its neither of them i say that the best invention of all time is light. Now let me tell you why, I use a lot of technology myself, From texting on my phone to surfing on my computer to beating jordy on PlayStations and the one thing that these have in common is that without light they wouldn't exist because their would be no way for you to see what you were doing. Imagine having a phone that had no screen just numbers to call a speaker to hear and a mic to speak,their would be no such thing as texting. Imagine instead of a computer having a typewriter! or instead of Playing your Playstation or Xbox playing board games. Yeah they're not that bad but wouldn't you get bored, i know i would. Also all of our favorite tv shows from Teen Wolf to The walking dead to SpongeBob none of these would exist because their would be no tv! all we could do was watch plays but even those would have to be outside. Another reason light is the best invention ever is that without it nightlife would irrelevant what i mean by this is that their would be no night time moves no concerts no movies no parties no carnivals even soccer and football games would have to be played during the day and as a soccer star myself i know that playing at night with the lights on just feels better. The only move would be to sleep at 8 O"clock.. even on weekends , and here in december we would sleep at 5! and the average high school student wakes up at 6 if you do the math were asleep about the same amount of hrs that we are awake essentially half of our lives would be slept away, think of all the things we could be doing after 5 o'clock , We could finish that hw assignment from that one class or have a nice family dinner or even become a millionaire the possibilities are endless, Dreams could be made, love could be found ,children could be born All if we didn't Have to sleep at 5 O'clock. Speaking of sleep imagine little kids who are terrified of the dark having to sleep in pitch black just thinking of their cute little face almost scared to death makes me wanna cry, not only is it bad for the kids it would be bad for the parents as well because their little angels would be keeping them up all night long screaming and kicking! Then, to make matters worse these parents have nothing to do at night because again like i said there would be no nightlife. No clubs, No Bars no Parties or get togethers as adults say, so them too would be stuck at home. Imagine that mrs reiner, being stuck at home even on weekends when you don't have papers to grade, you would just sit there saying um Some might say we could use candles but in the kids sake, not only do candles run out their hot wax and flame are dangerous for the kids. Also candles can't light up our electronics, they can't be used for watching movies or tv show. they can't be used to project our phone computer or video game screens the list goes on and on! Also some might say we don't need all this technology that we could survive without it like in ancient times, but ask yourselves this, do you want to just survived or live life to its fullest So to conclude without light our lives would be very different from our schedules to our activities we do for fun. Everyday new cutting-edge technology is being discovered but it all started from light! everything and anything would be affected if we didn't have light!

Development in banking and finance Essay Example | Topics and Well Written Essays - 4500 words

Development in banking and finance - Essay Example With passage of time things turned more complex; bankruptcy of big financial institutions like Merrill Lynch, Morgan Stanley and Bank of America disturbed the sentiment of the market. Such state of affairs affected the global stock markets and soon almost all the developed nations were engulfed by economic recession (p.63-67) To support the economy, the government of different nations infused stimulus packages for injecting liquidity in the market. Government also provided bails to several corporate companies to save them from bankruptcy. The increasing financial crisis was aggravated by a decline in demand; hence government had to enhance spending so as to raise the demand. To raise the demand and boost confidence among the investors, government reduced tax rate on several direct as well as indirect tax instruments so that the investors can have more money in their hand. To boost expenditure among the investors and to enhance supply of cash in the market, government reduced prime lending rate as low as possible. From the above given fact it appears that government of almost all the developed nations are following expansionary monitory and fiscal policy. Through expansionary monitory policy governments were able to reduce the rate of interest to a great extent. Through open market operations the central bank enhanced total money circulating in the economy whereas the government enhanced the monitory supply through sovereign bond transactions. The governments of developed nation enhanced disbursement of cash through banking sector by reducing cash reserve ratio i.e. the cash which the banks need to maintain as deposit with central bank. Reserve banks gave loans to the financial instructions at lower rate so that they can disburse loans to the investors and supply of money increases. Interest rate is the most commonly used monitory tool to

Written report of Ma Wan - Essay Example Although Ma Wan is a small island, it has proved to be a favourable destination for international and local tourists (Sewell & James, 1995). It has a number of leisure places such as the Ma Wan Park, Noah’s Ark Museum, Ma Wan Tung Wan Beach overseen by the Leisure and Cultural Services Department and the Heritage Centre (Sewell & James, 1995). Ma Wan is an island and a relative small one and as such has a small number of inhabitants. One thing notable is the old abandoned houses that are found in sections of the island. The governments seem to have prompted an agenda of relocating some of the locals to ease population in this area. The reduction of the population had fallen to 800 in 2008 (You Lin Xu, 2011). Abandoned shops are visible, and schools too, one being the Kei Wai Primary School indicating that the locals had not been alienated to the outside world. Religion integration is well-bonded in Ma Wan. Noah’s Ark is also an important landmark in Ma Wan. It is based on the Biblical story about Noah. The presence of temples has been an indication of the preservation of Ma Wan’s religion. Presence of churches and temples places Ma Wan as a multi-religion region, and there has been a peaceful co-existence between these different groups. These indicates an important aspect of diversification around Ma Wan. Ma Wan transport has been significantly advanced, and the construction of Kap Shui Mun Bridge is an indication of this progress. However, though, the people of Ma Wan depend on water transport mainly to get to the mainland and also the tourists mainly use water transport as part of their leisure activities. Therefore, it is an indication that Ma Wan has limited connection of roads to the mainland of Hong Kong. As such, the locals offer transport services through boats. A harbour is also present in Ma Wan, and this has been as a result of the evacuation

Relations Between The US And India

Relations Between The US And India India and Pakistan have been in the interest of the United States due to their strategic positions and roles the South Asia. This memo will describe an overview about US relations and policies toward India and Pakistan. It will also provide recommendations that Vietnam must support US policies toward India because of the benefits for our country regarding to economic development, nuclear energy plan and defense and security stability. This memo uses realism and systemic approach as the analytical framework. It studies and analyzes the relationships and policies in the concern with power and security in the whole international system. BACKGROUND Relations between the US and India After Indian independence in 1947, the relationship between India and the US was not warm. US policies regarding to India -Pakistan dispute over Kashmir was one issue that deteriorated India US relations since the US was supporting Pakistan over India. Even during Sino Indian war in 1962, when the US provided India with military support, the relationship did not improve much. During Cold War, the US was concerned about the neutrality of India because India signed the Indo Soviet Treaty of Peace, Friendship and Cooperation in 1971.  [1]  During this period, the US viewed India as just a regional power with little global weight and concentrated more on supporting Pakistan, which was invaded by the Soviet from 1979.  [2]   After Cold War, the US lessened assistance to Pakistan, leading to a better relationship with India. Furthermore, since 1991, India has transformed the economy and opened the country to foreign investment. With rapid growth, India has become an emerging economic power in the world and had opportunities for economic engagement with the US.  [3]  The relationship between the countries has been positively shifted, especially in economic development, security, military and nuclear cooperation. However, it has been constraint mainly because of the complication of the trilateral relationship: the US India Pakistan. Current Policies of the US toward India Economic Policies: The US strongly supports Indias economic reform, and develops trade and investment partnership with India. Bilateral goods trade revenue between the two countries increased 932.14%, from $5.6 billion in 1990 to %57.8 billion in 2011.  [4]  US foreign direct investment to India was $27.1 billion in 2010, a 29.5% increase from 2009.  [5]   However, India has extensive trade and investment barriers, such as heavy government involvement in the banking and finance sector and demanding regulatory structures. Therefore, the US has encouraged and supported India to remove those barriers.  [6]   Security and Military Policies: The US and India share a variety of common strategic priorities. Both are concerned about the rise of Chinas power and do not want China to dominate Asia. They also consider the security of energy lanes in the Indian Ocean as a critical factor to their national security.  [7]  With those strategic policies, the US has had Indias in its side in a number of situations. India supported the US in three resolutions against Irans nuclear programs and in the reconstruction in Afghanistan. Indian military forces have also had tight contacts, joint patrols, joint training and exercises with the US.  [8]   The US has been selling defense equipment to India. By 2011, US arms sales to India reached approximately $8.83 billion.  [9]  However, US arms sales decisions to India still depend on the stability of the region, especially the balance between India and Afghanistans military. The US is also concerned about the engagement between India and Russia and Israel, the two major suppliers Indias army.  [10]   Another remarkable point in US policies toward India is that US President Barack Obama publically announced that the US will supports India to be one permanent member of United Nation (US) Security Council if it is expanded.  [11]  Although it does not mean that the Council will be reconstructed and India will be able to have a permanent seat soon, Obamas announcement has been an effective diplomatic gesture to show the importance of the US to India and to strengthen their relationship.  [12]   Nuclear Policies: US nuclear policies have been to cooperate with India. By doing so, the US not only to be able to sell nuclear fuel, technology and reactors, but also build up India as a counterweight of China in Asia.  [13]  In October 2008, the US Congress approved an agreement facilitating nuclear cooperation between the two countries. Although the deal has brought benefits for both the US and India, it has faced criticism and responses from many other countries. The deal has been said to go reversely against the international efforts of nuclear nonproliferation. It can also increase the risk of a nuclear arms race in Asia, when Pakistan, Iran and North Korea are attempting to develop their nuclear weapon programs as well.  [14]   Relations between the US and Pakistan After Pakistan became independent in 1947, the US provided military aid to Pakistan but did not seek deeper relations. However, in 1965 when the Indo Pakistan war occurred, the US suspended the assistance.  [15]  In 1979, the US discovered that Pakistan was building a uranium-enrichment facility in response to Indias nuclear program, and then stopped the aid.  [16]   In the same year, the Soviet invaded Afghanistan, leading to the reconnection between the US and Pakistan. However, once again, the discovery of Pakistans nuclear weapon programs in 1990 caused to the suspension of military assistance from the US.  [17]   The nuclear tests in 1998 led to new US sanctions to Pakistan. However, the 9/11 terrorist attacks on the US (2001) was a turning point from which Pakistan started to be valuable for the US in the counter-terrorism campaigns. Economic assistance came back, and Pakistan became a major non-NATO ally of the US.  [18]  But since May 2011, after US intelligence killed Osama bin Laden in Abbottabad, Pakistan, the relationship has reached to its lowest point since 2001.  [19]   Current Policies of the US toward Pakistan: Economic Policies: In March 2009, the US develop an AfPak policy to emphasize that success in Afghanistan depend on actions taken in Pakistan. The US has increased annual aid to Pakistan from $600 million to $1.5 billion in five years. The new strategy has aimed to assist Pakistan to improve living standards of local people, especially ordinary Pakistanis along the border region and counter al Qaeda and Taliban propaganda.  [20]   Military Policies: Obamas administration now is still expanding Bushs policy of drone attacks to the Taliban in the north-west of Pakistan.  [21]  This strategy has shown its effectiveness in killing Taliban groups, but it has alienated the public because of innocent civilians being collateral damage. According to the Bureau of Investigative Journalism, a non-profit organization in England, between 474 and 881 civilians in Pakistan have been killed in strikes from 2004 to 2012.  [22]   The US has assisted Pakistan with Train and Equip programs. US arms and security assistance has included helicopters, infantry arms, advanced identification systems and police training, with the purpose of strengthen Pakistan domestic stability and law enforcement capability.  [23]   Nuclear concern: WikiLeaks in 2010 revealed US diplomats fear that Pakistans nuclear weapons program could lead to the weapons falling into the hands of terrorists or a devastating nuclear exchange with India.  [24]  However, US responses toward Pakistans nuclear programs are still unclear. Challenges the US Faces: Challenges for the US in South Asia are the quadrilateral relationships between the US, India, Pakistan and China. These relationships are extremely complex. India and Pakistan have had a long history with wars and conflicts. The Kashmiri sovereignty has been a major issue of tension. The two countries also appear to be fighting a shadow war inside Afghanistan.  [25]  The US India and the US Pakistan relationships themselves are constraint because of each other. The tie between the US and Pakistan displeases India and vice versa. Chinas South Asia interests are firmly linked with Pakistan. This situation is problematic not only for the China India relationships, but also for the China the US ones because of significant US investment in Pakistan. RECOMMENDATIONS Vietnam has strategic relations with India, but not really with Pakistan, thus at the moment we just need to focus on US policies toward India. In order to maintain peace in the region, develop relations and get benefits from both India and the US; Vietnam must support US policies toward India. Following are the reasons: Benefits for the Economy: US economic policies toward India bring Vietnam benefits, not harm. The US encourages and supports India to remove trade and investment barriers,  [26]  opening more favorable conditions for Vietnam to trade with India. Both India and the US are important economic partners of our country. By supporting US policies, we can maintain and develop economic relationships with both countries, with the purpose of strengthening our economy. Benefits for the Nuclear Energy Plan: US policies toward Indias nuclear energy program benefit Vietnams plan of building nuclear power plants. The US has showed its interest in assessing other countries nuclear programs to see whether they are for peaceful purpose or not. Having an example of a peaceful energy nuclear program being supported by the US, we can confidently develop our plan. In addition, India has been a partner for our program, apart from Japan and Russia.  [27]  With US technology transfers, India can assist Vietnam more effectively. Cooperation with India will be important to us because we might no longer rely on Japan, which might exit the nuclear industry due to the damages after the tsunami in 2011.  [28]   Benefits for Defense and Security: The US India relations is a counterweight of China in Asia, especially in the East Sea conflicts. Supporting US military and security policies toward India brings Vietnam advantages in championing our targets from the disputes. High level of military exchanges, joint training and exercises between Vietnam and India,  [29]  with US support, has been strategic for us to deal with China. Backing India to be a permanent member of the UN Security Council is also beneficial for Vietnam due to the relationships between the two countries. CONCLUSION US relations with India and Pakistan have had a long history, with significant changes after each period of time. The US has had special interest in both India and Pakistan because each country has strategic importance for US power and security. With regard to this situation, Vietnam must support US policies toward India because they bring us benefits for our economy, nuclear energy plan and defense and security stability.
