This could be well achieved by means of introducing new software called the voice to text converter (VoTC). INTRODUCTION: Mobile communications and wireless networks are developing at an astounding speed, with evidences of significant growth in the areas of mobile subscribers and terminals, mobile and wireless access networks, and mobile services and applications. The present time is just right to start the research of 4G mobile communications because of à ¢Ã¢â€š ¬Ã‚ ¢ Possibility, according to the historical indication of a generation revolution once a decade, and now we are near the end of 3G standardization phase and the beginning of 3G deployment. à ¢Ã¢â€š ¬Ã‚ ¢ Necessity: according to 3G goals, 3G is necessary but not sufficient to the mobile communication strategy, in which many problems are only partly solved and there are still many problems left to be solved in the next generation, i.e. 4G. There is plenty of related research on the next generation mobile communications. However, most of the ongoing research can be classified into two different classes: 1) Many of the related 4G research focuses mainly on one specific technical area, such as distributed computing, mobile agents, multimedia services, or radio air interfaces, etc. 2) Some pieces of research are interested mainly in 4G scenarios from the standpoints of service provider or user, or a market analyst, from a less or non-technical viewpoint. The difference of this paper to other related pieces of research is that we are going to present overall visions on the features of 4G mobile communications, based on a feature framework and provide detailed proposals to respective support techniques and research topics. This paper is organized as follows. The next section consists of a brief review in the development history and status of mobile communications, together with an analysis of the problems of 3G and developing trends summarized. The following text is comprised with, after a survey of related 4G perspectives, we present an overall 4G feature framework based on the key concept of integration, and then describe each of the two features (diversity and adaptability) of the three relevant targets (terminals, networks, and applications) in detail. The heart of this paper deeply discusses the adaptability feature of each three targets in the entire 4G domain from a technical standpoint, in which promising techniques and possible research issues are proposed. The skeleton of this paper figures out a short summary on 4G visions. The declining part concludes the paper. A. 4G Feat urge Framework We summarize our proposal of 4G features with one sentence, or even more simply, with one word: integration, i.e. seamless integration of terminals, networks, and applications (together with users). A more detailed analysis and explanation of the definition is as follows. 1) The discussion domain includes three relevant targets, i.e. terminals, networks, and applications. Out of the 4G domain, the user is the only target. 2) The kernel word of the definition is so-called integration, which means the convergence of first the three different targets; second the various modes of each target, which lead to the feature of diversity. 3) The modifier seamless, which means the character and requirement of integration, implies the support of the adaptability feature between the three targets, each one of which is largely miscellaneous. . In order to clarify the concept, we define two kinds of diversity: external diversity and internal diversity. à ¢Ã¢â€š ¬Ã‚ ¢ External diversity is outside the target, which brings along the demand of the adaptability feature to all targets. à ¢Ã¢â€š ¬Ã‚ ¢ Internal diversity is inside each of the targets, and it acts as the solution for adaptability requirements. In short, the need for adaptability is caused by external diversity, and it is solved by internal diversity. Here both the external and internal diversity of users are the cause of all adaptability requirements, which implies that the user is out of the technical domain of 4G visions. The two main features. I.e. diversity and adaptability of the three targets terminal, network, and application are described in detail in the next section. B. 4G Feature Description 1) User Diversity: The external diversity of users, i.e. people in different situations, includes e.g. culture, educational background, economic capability, physical property, personal preference, etc. The internal diversity of users, i.e. people with different interfaces, include e.g. vision, hearing, speech, touch sense, hands and fingers, body, etc. Note that as for users, both their external and internal diversity are to be adapted by the other two targets: terminal and application. Moreover, for adapting the two kinds of user diversity, both the external and internal diversity of terminals and applications are the solution. 2) Terminal Diversity and Adaptability: The terminals external diversities are the differences of terminals in both static and mobile attributes. Static attributes include e.g. functionality, weight, size, battery life, human interface, antenna, processing capability, security, style, and cost. Mobile attributes include dynamic attributes of both temporal and spatial features. The former category contains e.g. moving speed and acceleration, along with stationary, pedestrian or vehicular qualities, while the latter is connected to spatial range, e.g. indoors, on-campus, in urban and rural environments, and also direction. The internal diversity of terminals means that one terminal may integrate multiple functions, modes, interfaces, flexibilities, etc. There are three targets for terminal adaptability. For users, it includes the provision of different terminals to satisfy different users and an individual users various requirements. As for applications, we hope that miscellaneous services can be delivered to one single terminal. When networks are concerned, a single terminal can reach a wide range of networks despite of location and mobile rate. 3) Network Diversity and Adaptability: The external diversity of networks is obvious. Internet is assorted by nature, while wireless networks keep the same property. For instance air interfaces can integrate all kinds of standards and work on different frequencies. Moreover, multiple operators deploy networks with multiple standards and protocols. The internal diversity of networks means that one network can interconnect with other different networks and transfer various kinds of loads, e.g. cellular systems with various coverage. Three targets are related to network adaptability. In reference to terminals, network adaptability aims to make multiform mobile devices with a wide range of moving speeds and mobile areas connectable to wireless networks. For applications, there is a requirement that any type and/or quality of service can be delivered through diverse fixed and mobile networks in the most suitable and efficient way. The target for networks themselves is to make it easy to build a 40 feature framework in order to be transmitted correctly and efficiently. We present the support techniques for each of the above features in the next forthcoming text. D. 4G TECHNICAL PERSPECTIVE It is obvious that 4G, just like all the previous generations, is driven not only by technology, but also by market requirements. This section mainly discusses, from a more technical perspective, possible topics for research and promising techniques of 4G, and focuses mainly on those techniques that give support to the main feature of adaptability by internal diversity of targets in the 4G domain. Fig. 2 gives an illustration of the discussion domain of 4G. Technical details are ignored here because of the length limitation of the paper. The various possibilities of competition among services are illustrated above. A.Terminals In order to adapt to the diverse applications and networks, together with the various requirements of users, the terminal domain must possess both internal and external diversity. Support techniques of the field may include the following: 1) User interfaces of terminals vary from traditional keyboard, display, and tablet, to new interfaces based on Lasers Speech, touch, vision, soft buttons, etc. This will be common at a time when one terminal has multiple user interfaces. 2) Adaptive techniques such as smart antennas, software radio, and smart transceivers, enhance interoperability through simultaneous support of several radio interfaces in a single terminal. This makes a terminal roam able across any air interface standard and connectable to any wireless access point by exchanging configuration software. These approaches can also be used on wireless access points as an advanced smart base station. 3) Terminals will be aware of location and context, often based on some wireless low power sensors that are human- sensitive and/or environment-sensitive in order to monitor and interact with the physical world to report the human and/or environmental factors. The advances in this area have been used in e.g. wearable computers as a novel terminal type. 4) An intelligent terminal is able to dynamically improve its processing capability in order to contain various services. Some function modules can even be downloaded to a terminal when needed. B. Networks More advances in networks are needed to keep pace with the rapidly changing terminals and applications, as follows: 1) Smart antenna, software radio, together with advanced base station are the key techniques to achieve adaptability of wireless access points to diverse terminals, i.e. to make radio systems and air networks re-configurable. 2) Hierarchical and ubiquitous as well as overlay cellular systems, including Pico cell, micro cell, macro cell, and mage cell ones, implement seamless network interconnection of both symmetric and asymmetric nature, and seamless terminal handoff of both horizontal and vertical levels respectively. 3) Network layer hierarchical mobility management based on Mobile IPv6 and Cellular make networks portable and adaptable of self-deployed wireless networks to introduce this concept IP brings quick and seamless handoff to terminals. The Mobile IPv6 also presents a great contribution to the adaptability of heterogeneous networks. 4) Ad hoc wireless networks are a kind, and thus dynamically share unlicensed radio spectrum 4G Mobile Communications 5) Network reconfiguration can be obtained by the reconfiguration of protocol stacks and programmability of network nodes. Thus, it can adapt dynamically to the changing channel conditions and low or high data rate users. 6) Miscellaneous services can be delivered through a mixture of transmission networks including unicast, attribute, importance, bandwidth demand, or data stream type, multiple levels of Quos can be defined for various services. multicast, and broadcast ones. According to the service types, e.g. real-time 7) Network resource can be dynamically allocated to cope with varying traffic load, channel condition, and service environment. Traffic conditions will be dynamically monitored and controlled via techniques such as distributed and decentralized control of network functionalities. C. Applications Adaptability will be one of the basic requirements to the development and delivery of new mobile services. Promising techniques and possible topics may include: 1) Mobile application should refer to a users profile so that it can be delivered in a way most preferred by the subscriber, such as context-based personalized services. This also brings the applications with adaptability to terminals that are moving in varying locations and speeds. Micro-sensors and GPS receivers are the main driven techniques. 2) Techniques such as adaptive multimedia and unified messaging take the terminal characteristics into account and ensure that the service can be received and run on a terminal with the most suitable form to the host type. 3) Intelligent mobile software agent is a common technique to all of the three targets, which act as a platform for service development, delivery, and auto-configuration. 4) Applications can negotiate with networks so that they can be transferred with the most efficient channel, e.g. indoor networks or WLAN or cellular systems in a wide area. Services will be tailor able in order to fit the different network environments and the varying traffic conditions. 5) Services and applications can also be smoothly delivered across a multiple domain of operators and service providers. 4G VISIONS SUMMARY We present Table 2 as a summary of the discussion above, which is a continuum of Table 1 with visions of 4G features. CONCLUSION This paper presents 4G visions from a technical perspective. After a brief review of the history and status of mobile communications, we propose a 4G feature framework, in which features of 4G mobile communications are defined. The framework is based on the key concept of integration, and it has the following characteristics: 1) Targets in the framework include users, terminals, networks, and applications, which compass the entire technical domain and operating environment of 4G. 2) Core features of 4G are described as diversity and adaptability of the targets, leading to seamless integration. 3) The feature of diversity includes both external and internal diversity, in which adaptability is caused by external diversity and is solved by internal diversity. Technical perspectives are presented for each of the features in the paper, in. which also some promising techniques and possible research issues of 4G are introduced. The proposed framework provides a layout view on future communication systems, and challenging research topics are figured for guiding systematic research of 4G 4G VISIONS SUMMRY Property 4G Starting Time 2010-2012 .

Marketing Essay

Crispy Crunch’s main problem is that they haven’t advertised their product in many years. Since then the target market has changed a lot and has a very high multi-tasking behaviour. It is hard to pin point the exact needs and wants of this culture anymore except for one thing, they are all very technologically routed. With the internet at our finger tips, TV whenever we want, and smartphones in everyone’s pocket. That is the only thing you can really count on this day in age. The chocolate bar market is mature and experiences only modest growth annually. There are 4 major players all with similar marketing strategies; find something unique in the product and promote it. Chocolate bars can be found in the same locations and are sold at very similar prices so they must use marketing communications to distinguish themselves. Crispy Crunch has had little to none in the last five years. Crispy Crunch’s goal is to break into the top ten again and increase market share from 3.5% to 4% within 12 months. The current awareness of Crispy Crunch is 35% among the target market, which must increase significantly in order to increase market share and profits. My main recommendation is to reach out to the target market using the only real linking factor among them; the internet. I think rich media is the best way to reach this audience because it makes use of technology and is available to audiences of many different tastes and lifestyles at all hours of the day. Search advertising is when an advertiser is listed within or alongside search results in exchange for paying a fee each time someone clicks on the listing in those search results. If Crispy Crunch were to apply that type of advertising they could buy such words as â€Å"chocolate†, â€Å"crispy†, or â€Å"delicious†. When someone searched a phrase with these words they would see Crispy Crunch’s ad. Pros This is a great way to advertise since you only play for the clicks you get. It is available 24/7 to a large audience and 80% of all internet traffic begins at a search engine. Cons This form of advertising can be an annoyance to consumers, therefore they become put off the product. Rich Media Rich media Incorporates animation, sound, video and interactivity into the advertising messages, like a short commercial. Marketers have found that a 10-second ad is the maximum acceptable length for an online video ad, and if it is to be viewed entirely it must be entertaining. Pros The similarity to television makes it attractive to traditional advertisers. Many TV shows are now being viewed online; these ads are often placed at the beginning, between scenes and at the end. They are available 24/7 to a large audience. Cons Sometimes it can be hard to make an ad interesting in that short of a time frame. Some viewers find these ads to be an annoyance. Mobile Advertising Advertisers are trying to capitalize on the popularity of cell phones by sending ads via text message. Marketers interested in reaching younger targets are getting involved with text messaging. They are asking consumers to get involved with their brands by running promotions that include short codes with their marketing material, often found on posters, packaging, bottle caps, etc. Consumers can enter or scan codes to participate in contests, download free music, and get ring tones and prizes. Pros This is a great way to advertise because of the speed, directness, portability, and low cost. It is very common with younger target markets. Cons These messages are often seen as an annoyance and intrusive and are too closely related to telemarketing. Some of these ads may even cost the consumer for the data they use. Recommendations I recommend that Crispy Crunch begins advertising with the use of rich media. I think this is best suited to reach their target group which has a high multi-tasking behaviour. Many people in the age group of 18-29 year olds have hectic schedules and are now watching episodes of their favorite shows online because they are not always able to watch it and this form of television has allowed them a more flexible lifestyle around their shows schedule. Rich media also provides 24/7 access, it can reach many people at once and it is not as invasive or annoying at other methods of advertisement such as direct response, text message or email while still being very cost effective. I would also urge Crispy Crunch to stick with their previous slogan â€Å"The only thing as good as your Crispy Crunch is someone else’s.† as well as the general message of the campaign. The ads were short, funny, and to the point. I think that the people in their target market have most likely never seen the previous ads or have forgotten about them. Sometimes bringing back the old is very well received. A&W did very well bringing back the vintage vibe of their restaurants. The ads from the 1989 campaign were very well received and upped market share then and I’m sure they could do it again with the same overall message, they just need the attention.

The Grotesque In Gothic Literature The Characteristics...

The grotesque in gothic is usually the behavior of a man (or women,) who battle with an internal conflict and they are also, usually sick. When an individual reads gothic stories, one can sometimes miss-interpret what they have read. It is common knowledge that when we are younger we understand things differently from when we grot be adults. We can infer that if one was too read gothic literature as a child, one would find it humorous, versus if that individual was to read gothic literature as an adult. As an adult you might not find the text humorous, but rather disturbing. Naturally, the gothic literature is disturbing because it showcases the darker sides of humans; one reads the conflicts the characters are having and one is likely to†¦show more content†¦There are thousands of gothic literatures that follow this theme. To come to terms with the extent of how gothic writers impacted psychology, one should know the history behind psychology. The first American psychology laboratory was opened in 1883; the first American gothic novel titled Wieland, was published in 1798, eighty-five years before the laboratory opened. Somnambulism was discovered in the early 1900s; somnambulism is the fact or habit of walking about and performing other actions while asleep; sleep-walking. (Somnambulism, n. OED Online, Oxford University Press, June 2017, www.oed.com/view/Entry/184510. Accessed 16 November 2017.) A man by the name of, Sigmund Freud spoke about sleepwalking to the Vienna Psychoanalytic Society in 1907; Charles Brown published his short story Somnambulism. A fragment in 1805, one hundred and two years before Sigmund Freud formally addressed the mental illness. In 1887 the mental illness, schizophrenia was discovered by, Dr. Emilie Kraepelin; however, the mental illness was not named until 1911 by Swiss p sychiatrist, Eugen Blueler. Edgard Allen Poe published his short story A Tell-Tale Heart in 1843; A Tell-Tale Heart was narrated by a schizophrenic man. A key person in the gothic genre is Edgard Allen Poe. Edgard Allen Poe wrote numerous stories about a conflicted person(s).
