Algorithm to Enhance Radio Wave Propagation Strength

Algorithm to Enhance Radio Wave Propagation Strength A New Algorithm to Enhance Radio Wave Propagation Strength in Dead Spots for Cellular Mobile WiFi Downloads Using Cloud Networks Signal loss is a major problem for cellular wireless devices, resulting in dropped calls and failure in downloading data. Our research uses a combination of different interaction models to provide an easy interface to replace traditional control methods for maintaining signal levels. The lossy WiFi wave propagation around and within buildings is studied utilizing college buildings at the University of Bridgeport (UB) campus in Bridgeport CT. These buildings serve as good experimental settings because they exemplify typical signal dead spots, locations where little to no WiFi signal is available. In this paper, we investigate path loss propagation inside and outside buildings and we identify and categorize these problems. We then apply our path loss propagation algorithmic models to show that signal strength is significantly improved when compared to existing algorithms. Finally, we show the efficiency of our model and explain the specifics of our algorithm. Cellular Mobile Communication keeps growing so fast on the market worldwide so that they become our everyday companions. Over the last twenty years, globally, Mobile Communication users have raised a specifically rich multimedia service which forces telecommunication vendors as well as the operators to set significant efforts in order to fulfill client’s needs. The use of Wi-Fi for internet is widely increasing especially in mobile devices where Wi-Fi enabled, which gives results in expanding hotspots, and user acceptance also grows. Cisco Visual Networking Index (VNI) presented its research about global mobile data traffic, and VNI research indicated that this traffic will increase 18-fold from 2011 to 2016, and will reach 10.8 exabytes per month. Recent technologists and mobile industries never viewed the roles for Wi-Fi in the new phones networks. The changes in the mobile and the offloading data traffic to Wi-Fi can and it plays the significant role to avoid clogged networ ks are realized by mobile operators [12]. From all these we conclude that the key component of the information security is the data transfer and it’s daily importance in our life. Wireless Local Area Networks (WLAN) gained high acceleration, the reason of the necessity to pre-evaluate signals that are transmitted under Line-of-Sight (LOS) and /or none (NLOS) radio wave propagation in the indoor environments. These transmissions have main problem which is the difficulty to predict indoor radio wave propagations because of the invisibility between the transmitter and the receiver [15]. Related work Yuko MIURA, et. al. [1] proposed a propagation model which accurately predicts outdoor-to-indoor propagation loss; this model depends on the angle dependency of the losses with the paths that penetrate the indoor area. Radio waves transmitted from the base station first propagate outdoors to the building’s external wall. Next, the radio waves penetrate the structure’s external wall. Last, the penetration waves propagate inside the building for the receiver. Outdoor-to-indoor propagation loss is estimated by predicting the propagation losses of those three parts. The losses of those three propagation processes might be calculated individually, and the path loss between base station and mobile station is usually expressed since the amount of these losses in dB [1]. Greg Durgin et. al. [2] developed measurement-based path loss for propagation prediction; these measurements aided the development of outdoor-to-indoor communication systems for wireless internet access, wirele ss cable distribution, and wireless local loops. Iskandar et. al. [3] evaluated the propagation loss as a function of elevation and azimuth angels, and observed the link budget in the estimation to the required transmitted power at several transmission rates of IMT-2000. Gerd Wà ¶lfle et. al. [4] proposed a new concept called dominant model in which focuses on the dominant paths between transmitter and receiver for the planning of wireless networks. [4] Prepared a comparison between cellular or WLAN in urban considering indoors either direct ray or ray tracing propagation and urban city centers in multi-floor buildings. Oliver Stà ¤bler et. al. [5] presented a deterministic approach for the evaluation of 3GPP Long Term Evolution (LTE) networks in urban and indoor, beside evaluated the signal levels in the expected MIMO capacity. N. Faruk et. al. [6] conducted measurements at 203.25 MHz and 583.25 MHz frequencies along ten routes in Ilorin City, in order to fit the measured data wi th lognormal propagation loss, [6] used least square regression method, and investigated the behavior of the TV signals in the same environment in building penetration loss across the routes. Thomas Schwengler, et. al. [7] presented propagation at 5.725 GHz – 5.825 GHz within the U.S Unlicensed National Information Infrastructure (U-NII) band. Measured propagation path loss in a residential area at 5.8 GHz. Separated the data sets into line of sight (LOS) and non-line of sight (NLOS), as much as obtained noteworthy results since propagation models were designed for cellular and PCs use at lower frequency and narrow-band channels. Sheryl L. Howard et. al. [8] presented the use of error-control coding (ECC) which used in wireless sensor networks (WSNs) in order to determine the energy efficiency of ECC in WSNs. As much as derived an expression for critical distance dCR, where the decoder’s energy consumption per bit equals the transmit energy savings per bit, also showed that in crowded environments and office buildings dCR dropped significantly to 3m or greater at 10 GHz without considering the interference. Alyosha Molnar, et. al. [9] presented 900 MHz, ultra-low power RF transceiver for wireless WSNs, and demonstrated them to communicate over 16 meters through walls at a bit rate of 20 kbps. Jun Wang et. al. [10] used an adaptive back-off strategy to achieve fairly uniform cluster head distribution across the network.

Hills Like White Elephants Essay

Ernest Hemingway’s short story â€Å"Hills Like White Elephants† touches on an issue people have faced in the past and continues today: communication problems in a relationship. The ability to communicate your feelings to another person during complicated times reveals the true strength in a relationship. Hemingway tells his story through conversations between the two main characters, the American and the girl, named Jig. The characters face the harsh reality of an unexpected pregnancy and conflict is created through their dialogue. Their obstacle is complicated by their inability to deliver their differing opinions to each other. The couple’s failure to communicate their opinions straightforward turns the conversation into a tactic of manipulation. On the surface, it seems the American is the one doing the manipulation and trying to persuade the girl to have the abortion, but when Jig’s dialogue is looked closer, it’s clear that she participates in attempting to control the conversation, as well. Regardless of who is more successful, their relationship is damaged forever. To begin, the man does not want to be forced to deal with the complications of starting a family and giving up his lifestyle of travelling. He wants the girl to have an abortion, but he wants her to feel like the decision she makes is that of her own. The truth is he believes and knows his words will play a huge influence on her decision. After a few drinks, the man brings up the sensitive issue to the girl by choosing his words carefully: â€Å"It’s really an awfully simple operation† (Hemingway 133). The man tries pushing the issue further by inserting his own judgment and assuring her that â€Å"they just let the air in and then it’s all perfectly natural (133). His manipulation can be seen clearly when he suggests â€Å"[The baby’s] the only thing that bothers us† (133). It is clear that their relationship has not been the same since hearing news about the baby. I think she begins to realize that she is left with the choice between having the baby or being with him, which could be depicted when she â€Å"put her hand out and took hold of two of the strings beads, â€Å"referring to only two people being able to be together: her and the baby or her and the man. The man is also planting the idea into the girls mind that he wants her to have a say in the matter and to soften its impact. â€Å"You’ve got to realize†¦ that I don’t want you to do it if you don’t want to. I’m perfectly willing to go through with it if it means anything to you† (134). Yet, when asked if the baby means anything to him, the man replies, â€Å"I don’t want anyone else†. In this line the American is referring to the baby in the girl’s womb and is saying that he wants only her. While its implications are insensitive, the man believes he is appealing to the girl’s desire for a man devoted to her. Instead of telling Jig that he does not want a baby to complicate their lives, the man tries to make it seem like an abortion is the best thing for the couple through his careful manipulation. The man’s manipulation is very noticeable, but he is not the only one who can play that game. On the surface, the girl appears helpless and dependent, but if viewed from a different perspective she could be seen as manipulative. Hemingway names her â€Å"the girl† to portray her as somebody who is naive and immature. She appears to be dependent on the man by asking him questions such as, â€Å"What should we drink?† (132) or â€Å"What does it say?† (132). However, she is much smarter than she may seem and communicates her feelings through indirect ways without being offensive to the older man. During their conversation about the drinks tasting like licorice, the girl comments, â€Å"Everything tastes of licorice. Especially all the things you’ve waited so long for, like absinthe† (132). She is trying to show her frustration towards the man in a subtle way. Her frustration is built on the fact that, despite always wishing for a baby, she might not have that chance anymore if she decides to have the abortion. The girl also makes it aware that her frustration runs deeper into their relationship. Upon trying a new drink, Jig questions their life, â€Å"That’s all we do, isn’t it — look at things and try new drinks?† She uses â€Å"all† in a desperate attempt to show the man that she is bored of her life and their relationship, which Bauer suggests â€Å"does not seem to be moving into any kind of commitment† (Bauer), that she deeply wants. As the man suggests that everything will be better after the abortion, The girl reacts, â€Å"And you think then that we’ll be alright and be happy† (133). Without the man even realizing, the girl, to me, has gone from uncertainty to certainty because she did not have to ask the question, already knowing that, as Bauer suggests, â€Å"Whatever they do about the baby, they will not go back to where they were† (Bauer). The girl seems to be in control of the conversation and in response to the man’s claim â€Å"I’ve known lots of people that have done it† (133), she offers sarcasm, â€Å"And afterwards they were all so happy.† The girl realizes that the man is clueless and will never understand. She realizes that she does not have a real decision in her abortion, feeling that the man has already made the decision for her. To compensate for her lack of autonomy, she wants to make the man feel guilty for making her have the abortion, so she tells him, â€Å"then I’ll do it. Because I don’t care about me† (134). Jill grows more explicit to her refusal, as she repeats several times â€Å"No we can’t† (134), ironically refuting his agreement of her own sarcastic statement, â€Å"We can have everything† (134). The man fails to understand her point of view and when Jill points out that â€Å"once they take it away, you never get it back† (134), the man thinks she is talking about their world of travelling, proving his ignorance and selfish desire to hang on to that. Yet if the girl carries the baby to term, the steady sex life that the American has enjoyed will come to an end: Not only will he have to forego sex during her pregnancy, but he will also have to fight for time to have sex with the girl once the babofy is born. Regardless of how seriously the American would take his responsibilities as a father, simply having the baby living with the girl at home would remind the American that he can no longer enjoy the fairly carefree lifestyle that he and the girl led prior to the baby’s birth. In a sense, he would be entering adult life a second time. Another aspect of youth that the American relives is traveling. In looking at the bags with labels from â€Å"all the hotels where they had spent nights† (Hemingway 76), he is not only thinking of their lovemaking but also of the different places they have been to. Not only is the American sleeping with a young woman but he is also taking her to countless different cities. The man and the girl are vagrants with money, seeing the world as if there were nothing else for them to do. This vagrancy also serves the purpose of masking the fact that the American is not moving quickly from one woman to another—indeed, that he cannot do so. Instead of moving between partners, he is moving between cities and countries. Were the girl to give birth to the baby, though, this traveling would likely be forced to stop—and even if the couple could still go to different places, they would either have to take the baby with them or find someone to leave it with. In observing the girl’s willingness to carry their baby to term, he sees that she is ready to grow up, to take on responsibility, to settle down.

Gender relationships in one of the two course plays Essay

Show how gender relationships in one of the two course plays is used by the playwright to throw light on our understanding of the main character, and the overall themes of the play. A view from the bridge is based in Brooklyn, an Italian community set in the 1950s. This particular part of the 20th century was seen as a rather sexist era. Men were a lot more dominant, women were known to stay at home cooking and cleaning-like every wife seems to do today! However aside from that, men felt like they had to be ‘men’ all the time. They felt like if they expressed their feelings, talked about their troubles or cried, these men would be laughed at and ridiculed. Eddie Carbone is a hard working longshoreman who works on the docks in his local area. Eddie is a typical bloke; he is a proud and stubborn man but is a loving husband to his wife Beatrice and a caring father figure to his niece Catherine. To the audience in the first part of the play Eddies comes across as the typical over protective father, however as the play progresses his feelings for Catherine become obvious that they are a lot heavier than what we are led to believe. Throughout the play we discover Eddie has fallen in love with his niece but his feelings are not sexual, in my opinion it is an obsessive need that cant be controlled as realized by Alfieri, â€Å"Something perversely pure calls to me from his memory – not purely good, but himself purely, for he allowed himself to be wholly known. † Alfieri realizes his feelings for Catherine are exceptionally powerful and that their would be nothing that Eddie could do to control them or dissolve them. Eddie tries to open up to Alfieri but can’t quite get the words out of what he wants to say. There is also one other particular part of the play when Eddie goes to see Alfieri in his office. Eddie goes to seek advice in order to prevent Catherine from marrying Rodolpho. Alfieri subtly mentions Eddie’s feelings but doesn’t quite mention them in so many words. Alfieri says, â€Å"When the law is wrong it’s because it is unnatural, but in this case it is natural and a river will drown you if you buck it now. Let her go. † Alfieri is saying that it is illegal for Eddie to get involved with Catherine sexually. It goes against the natural order. However the only advice Alfieri can give is to turn Rodolpho and Marco in to immigration, but with them being family it wouldn’t be a wise move. Eddies love for Catherine is so strong that he is willing to go to any means necessary to stop her marrying Rodolpho, making the call to immigration the only way out of the predicament. Eddie calls immigration, aware of his betrayal to Beatrice but he is doing it out of love for Catherine. Beatrice also realizes Eddie’s feelings for Catherine, in one [particular scene Eddie ad Beatrice have a slight disagreement over Catherine which later leads to an argument over lack of sex. Beatrice wants to know, â€Å"When am I gonna be a wife again, Eddie? † Beatrice says it in this context rather than come straight out and says when are we going to have sex again. This way avoids embarrassment but still gets the point across without having to actually say it. Beatrice wants to talk about what is happening but she can’t get Eddie to open up to her. Eddies feelings are putting a strain on the marriage, sexually, physically and emotionally. But Eddie,

Media Attention Has Brought The Issue Of Bullying - 931 Words

Jameka Smoot Professor Benie Colvin English 1101 9 April 2015 Media attention has brought the issue of bullying to the forefront. America is suffering from a bullying epidemic. Bullying is a national issue that has cost many lives within the past few decades. More than 160,000 children refuse to attend school due to fears of falling victim to bullying. There are several types of bullying and they all have been the cause and effect of many lives. Bullying can go anywhere from a cyber-setting, verbal, and the one we all know the traditional physical bullying. Bullying is intimidating because there are so many different methods of bullying. Many victims cannot defend themselves and do not believe reporting bully actions will help them or keep them protected, because they worry about retaliation, shame or the reputation of â€Å"snitching†. Many times bullying only occur to impress friends or to prove yourself to friends, because that person is unhappy themselves, or envious of their victim. There are other times where it is done simply for entertainment, revenge, or because their victim is different. Bullying targets would be of size, race or nationality, social status or class, gender and disabilities. Bullying has been the very cause of adolescent deaths within the past decades. An interview was conducted on a case where a victim turned bully, 12 year old, Richard Gale was body slammed trying to fight a fellow peer Casey Heynes.
