The paper addresses mainly error control technologies in view of wireless video. Several related 3GPP standards are introduced for readers in order to provide better understanding of wireless technologies. Actually, the authors pay attention to circuit-switch multimedia telephony, multimedia messaging services, multimedia broadcast service and, finally, end-to-end packet-switched streaming. It is necessary to admit that those technologies are discussed in terms of their supporting technologies. Need essay sample on "Wireless Video Applications" topic? We will write a custom essay sample specifically for you Proceed The main reason of discussing 3G technologies is that those standard descriptions give unbiased technical depth about the applications. When highlighting wireless video, the authors discuss future directions of error control technologies stating that layer 1/2 transport aims at providing two main conditions: burst errors during fading period and quasi error free. Therefore, it is suggested that error control technologies are limited in upper levels. It is required to focus more on extraordinary adaptability of error control in order to improve performance and reliability of 3G technologies. The authors identify rate control as essential technology that provides extraordinary adaptability to varying bandwidth. The authors recommend developing signaling link layer information to the upper layers. It would ensure progressive download applications. Nevertheless, one of the challenges of 3G technology is low levels of predicting how and when a new killer application will emerge. Main Points: 3G technologies include general packet radio service, enhanced data global system for mobile communications environment, high speed downlink packet access, universal mobile telecommunications system; 3GPP is viewed as mixture of wireless narrowband integrated services digital network; 3G is discussed in terms of circuit-switch multimedia telephony, multimedia messaging services, multimedia broadcast service and end-to-end packet-switched streaming; 3G technologies include all necessary protocols and meet standards; 3G will be characterized by large bandwidth, delay variations, two error states, error control adaptability, etc. Strengths and Weaknesses: The paper is a well-organized and coherent study of the subject. The author is very persuasive in defending the position that 3G technologies provide more benefits for consumers. One more strong point of the article is abundant data and example to provide better understanding of 3G technologies, especially wireless video applications. Actually, the paper addresses not only theoretical, but also practical implications of the arguments. Relevant conclusion summing up main points is apparent strength of the article. The paper is highly theoretical aiming at expanding existing knowledge of wireless technologies. Nevertheless, the paper is rather complicated for reading and it would be better to illustrate benefits of 3G by comparing it with other currently used wireless systems. Nevertheless, little is told about the drawbacks of 3G and wireless video applications. It seems that the author tries to conceal apparent disadvantages paying most attention to history of development and other related issues. References Etoh, M. & Yoshimura, T.

Advertisements Description of Amara Hotels and Resorts, and City Seasons Hotels

Advertisements Description of Amara Hotels and Resorts, and City Seasons Hotels Advert 1 The advert shown below (see Appendix 1) is a magazine advert by Amara Hotels and Resorts; it is an example of a simple but effective advert. From a glance, target market can learn of features and services in the resorts. It has combined bright (shouting) and dull colors (colors of harmony) well to create a pleasant feeling that visitors are likely to get in the hotels and resorts.Advertising We will write a custom report sample on Advertisements Description of Amara Hotels and Resorts, and City Seasons Hotels specifically for you for only $16.05 $11/page Learn More In the advert framework, target customers can learn more than four services offered by the hotels. The advert users get into details of the advert to understand what the hotel offers and its locations. The above attributes of the adverts make it simple and straight-forward. Color mix used in the advert is another strength portrayed; the colors make the viewers feel harmony and peace. They have been used to communicate the feeling customers are likely to get from their stay in the resorts. The advert background is not only made by appealing combination of shades, but the shades also communicate of more features likely to be found in the hotel. Since the advert is divided into different segments, each area seems to address particular service in the resort. The above gives the advert an upper hand and facilitates effective communication with target customers. The words correctly rhyme with the advert tag; they both have been used to bring more information of the resorts/hotels. The marketing team has used selected words to ensure that customers understand more about the facility and how well they can enjoy their time there. As if all above mentioned is not enough, the advert gives the company an opportunity to write to the customers on different issues regarding the resorts. The advert meets all the requirements of an effective advert (Rakesh, 2005). Advert 2 Advert 2 (see Appendix 2) portrays an ineffective advert made by City Seasons Hotels. There is an obvious mismatch between the name of the hotel and what is portrayed in the advert. When making adverts, it is important for the management to consider even the name of the hotel or the product. In this case, the name of the hotel suggests a place with numerous activities that meet the season of a year.Advertising Looking for report on advertising? Let's see if we can help you!

According to it, the place has more of indoor activities; it seems so because of the image of a beautiful interior design that the advert portrays. Although the finishing looks superb, the notion created by the name dismisses the good look. The color mix of the advert is not appealing; there is monotony of brown color which is supposed to be a shouting color and color of harmony. The background colors of the ad vert do not also go with each other well, there is nothing else communicated by the advert than what is coming out explicitly. Another problem that the advert has is the use of computer generated/artificial vegetations. The advert should show that the facility has well maintained vegetation. However, a closer look at the picture creates the impression that these trees are made to fit the situation or emphasize a decor and design of the interior, but here they seem to be out of place. The advert has concentrated on one area of its service, provision of accommodation. It has ignored the outdoor services that the resort offers. Since making an advert is expensive to every organization, it would be wiser to take all the possible advantages of it (Kerin Peterson, 2009). However, City Seasons Hotels failed to use their chance.

Enviroment Research Paper Example | Topics and Well Written Essays - 500 words

Enviroment - Research Paper Example There are varying sources of carbon dioxide especially the quantities found in the earth’s atmosphere. For example, environmentalists put the number at about 391 ppm (parts per million). Similarly, there is volcanic gassing, burning of fuels, combustion of organic matter and power generation that result to the excessive release of carbon dioxide in the atmosphere (Kemp 145). Other sources of carbon dioxide are cited as natural especially the decomposition of organic matter found in the grasslands and the forests. There is also notable emission of the gas into the environment from the respiration existing aerobic organisms. There are several effects of carbon dioxide in the environment in respect to the health of human beings and the immediate environment. For instance, in terms of positive effects, there are plant growths especially during the photosynthesis and transpiration processes. However, the negative effects supersede the positive such as the increase of the earth temperature. This eventually leads to global warming that finally leads to acidic rain. In other words, there is a mix of rainfall of carbon dioxide that comes in form of smoke from burning charcoal. On that account, the acidic rain affects crops by depositing acids especially in the oceans when it ends up poisoning sea creatures (McMichael & World Health Organization 145). In other words, the carbonic acid also affects crops by burning their leaves leaving traces of elements such as zinc and lead. The increase in earth temperatures also results to the warming of water bodies such as lakes, seas and rivers hence affecting creatures t hat have a direct dependence on water bodies. In the same view, there are also anthropogenic health risks of carbon dioxide that are paramount apart from the environmental effects. These are the human impacts of the gas upon the biophysical environments and other biodiversity resources.

Carbon Footprint Auditing and Management Assignment

Carbon Footprint Auditing and Management - Assignment Example According to the Intergovernmental panel on climate change (IPCC), over the next century the earth will experience an average increase of 3.0 to 11 degrees Fahrenheit. This revelation, alongside other credible projections, call for consolidated efforts in mitigating global warming and climate change, adopting necessary remedial measures, and coping strategies, especially for the poor societies (Mark, 2005:173). A recent estimation by the United Nations Environmental Programme (UNEP) indicates that households account a well over 30% of the carbon emissions in to the atmosphere every single day. It is against this background that putting measures in place to curb carbon emissions at the individual and house hold level is critical to all members of the society. Through the various energy usages in the house, the annual average carbon footprints stand at 5.89 tons of carbon. This is way above the national average of 4.46 tons per household. In simple terms, my operations at the house hav e resulted to the emission of these tones of carbon, into the atmosphere every year. With the recognition that carbon compounds, especially carbon oxides, are leading causes of the green house effect and the resultant global warming, this is an alarming rate of carbon emission, resulting from a single person. 1.2 Diagnostic Base-line Energy usage for the various activities in the house is the greatest carbon footprint source. Although the house uses electricity, which does not directly contribute to carbon emissions, it indirectly contributes to carbon emission. This occurs during the production of electricity at the power plant. The turbines that produce the electric power run on diesel generators, where as the distribution, step up and step down functions, are all depended on carbon producing fossil fuels. Therefore, any use of electric energy in the house contributes to carbon emissions in a significant direct and indirect manner (Charles, 2011: 45). After a careful analysis of t he processes and activities that dominate my carbon footprints, energy usage within the house is the leading activity, with conservation and efficiency measures lagging behind. In everyday, routine operation, revolving around cooking, ironing, electronics, and lighting have a profound effect on the amount of energy that the I spend in the house. Further, routine use of electric powered gadgets like the blower, the lawn mowers, and the washing machine also contribute to the high energy figures at the end of the month. This is made even higher by the heating of the house during the cold seasons, and the use of power to run the cooling systems during the hot weather days (Sarah, 2008: 39). Since all these energy-uses are pertinent, the focus turns to efficiency, conservation and green energy technologies, to contain the energy usages, and reduce carbon footprints. The first step will was to change the lighting system in my house, since all the bulbs in place utilize a lot of energy. Al so,

Critical Essay by Juda Smith Essay Example for Free

Critical Essay by Juda Smith Essay I think the nether grave is the best story, because it’s very relatable. Majority of kids get bullied and or go through a bad time at least once in their life, so they either find ways to escape it or lie to people about how â€Å"good† their life is so nobody knows how bad it actually it. People connect more with things they can relate too. Fact. But, ‘†A Sound of Thunder† is a better story that can be classified as science fiction because it has something to do with time travel, dinosaurs, and history. â€Å"A Sound of Thunder† fits into the science fiction category because it’s based on time travel, dinosaurs ruling the Earth, and staying on the correct path so he doesn’t â€Å"change the course of history†. Those are all science related things so that’s the science part. It’s fiction because its fact but science related. No one can go back in time or change the course of history that’s where the fiction comes into play. In the story â€Å"nether grave† it’s harder to classify it as science fiction, because it’s not like it has something to do with time travel or dinosaurs, but it does have to do with gaming and leaving behind his own life to be a jaguar in a video game life. It does have to with people and how their life effects their life decisions which is science. It’s fiction because people can’t trade in their bad life to be in a video game. In the story â€Å"A Sound of Thunder† he uses sensory imagery, which uses very descriptive words to evoke images of sight, sounds, feelings, touch, and smells. In the first line, the protagonist swallows and they tell us about the â€Å"muscles around his mouth† and he waves his hand, while in the background there comes a â€Å"sound like a gigantic bonfire.† In the story the nethergrave it was hard to tell you were in another world because of the lack of detail. They didn’t give you a time period too, so there isn’t really to relate to besides the fact that it’s about a boy who uses his computer to hide and lie about his life. The theme in the story â€Å"A sound of thunder† you have to stay on the correct path in life or it will go all wrong. The plans you thought you had will change and everything will be challenging and hard. In the stor y the â€Å"Nether grave†, the theme of the story I believe it is when you feel like your life is bad, don’t go on trying to hide what’s going on. I think the first story has the best theme â€Å"A sound of thunder† because it is true. If you don’t stay on the correct paths of life and associate yourself with good people, your life and plans  can all change. You can’t have the both of best worlds.

The Talloires Declaration :: French History Essays

The Talloires Declaration The Talloires Declaration was born in Talloires, France in 1990 at a conference attended by presidents and chancellors from universities around the world. They believe universities have a duty to take care of the land in order for it to be sustainable and support future generations. The intention of the creators was to find a way to incorporate environmental sustainability in all aspects of educational institutions. They came up with the Talloires Declaration which is an official statement comprised of ten how-to steps to create sustainability. It is supported by universities around the globe who want to incorporate sustainability and environmental literacy in the classroom, in research, in system operations, and in outreach programs. The claim of the Talloires Declaration is â€Å"University leaders must initiate and support mobilization of internal and external resources so that their institutions respond to this urgent challenge.† Already more thanthree hundred university presidents and chancellors from over forty countries have signed the declaration and have incorporated sustainability into their universities by following the framework set by the ten steps. To understand the Talloires Declaration, one must know what sustainability is. The dictionary definition of sustain is â€Å"to keep going: prolong.† Environmental Sustainability is a way of using resources so that they are not depleted and it is a way of living that uses environmental methods such as recycling, solar panels, and little use of resources. In universities across the globe, sustainability has not been incorporated in everyday campus life and this has caused concern about the environmental impacts of those institutions. Each of the ten steps of the Talloires Declaration is open for individual interpretation by each university. The creators purposefully wrote the steps this way because each campus has its own circumstances and environment. These guidelines ensure that universities follow through with sustainability because they motivate and inspire the establishment of a better world. It is good that the same steps are followed by all the universities, that they are dedicated to creating a sustainable future, and that they are held accountable for their actions. The first step of the Talloires Declaration is to spread the word of sustainability and the ways to develop it at the university.
