On the Delay of Geographical Caching Methods in Two-Tiered Heterogeneous Networks

Abstract We consider a hierarchical network that consists of mobile users, a two-tiered cellular network (namely small cellsand macro cells) and central routers, each of which follows a Poisson point process (PPP). In this scenario, small cells with limited-capacity backhaul are able to cache content under a given set of randomized caching policies and storage constraints. Moreover, we consider three different content popularity models, namely fixed content popularity, distance-dependent and load-dependent,in order to model the spatio-temporal behavior of users’ content request patterns. We derive expressions for the average delay of users assuming perfect knowledge of content popularity distributions and randomized caching policies. Although the trend of the average delay for all three content popularity models is essentially identical, our results show that the overall performance of cached-enabled heterogeneous networks can be substantially improved, especially under the load dependentcontent popularity model. Besides, Because of the limitation of research conditions, the total network delay, network cost and optimization of network parameters are not analyzed. Keywords: edge caching, Poisson point process, stochastic geometry, mobile wireless networks, 5G Introduction It is known that content caching in 5G heterogeneous wireless networks improves the system performance, and is of high importance in limited-backhaul scenarios. Most existing literature focuses on the characterization of key performance metrics neglecting the backhaul limitations and the spatio-temporal content popularity profiles. In this work, we analyze the gains of caching in heterogeneous network deployment, and consider the average delay as a performance metric. Firstly we use passion point process (PPP) method to build the model. This heterogeneous network consists of mobile terminals (users), cache-enabled s mall base stations (SBSs), macro base stations (MBSs)

全国在职研究生考试英语二卷

二卷模拟答案 Section A Directions:Translate the following passage into Chinese. Write your translation on the ANSWER SHEET. Discoveries in science and technology are thought by many to come in blinding flashes or as the result of dramatic accidents: Sir Isaac Newton noticed the falling apple in his garden and came forth with the gravitation law. This notion is obviously not true. Sir Alexander Fleming did not, as legend would have it, look at the mold on a piece of cheese and get the idea for penicillin there and then. In fact, he had experimented with antibacterial substances for nine years before he made his discovery. Inventions and innovations almost always come out of laborious trial and error. Innovation, as well as inventions, is like soccer; even the best players miss the goal and have their shots blocked much more frequently than they score. Section B Directions:Translate the following passage into English. Write your translation on the ANSWER SHEET. 自然界开始了一次新的实验。人类不再只是能适应某一特定的环境,而是获得了能适应 任何环境的能力。他们分散到世界各地,在迁移中不断变化,直到成为在地球上分布最广的 物种。人类在身体和文化方面都适应于他们迁入的新环境。居住在赤道附近的人为了在强烈 日光下保护自己,渐渐地有了黑色皮肤。迁移到寒冷地带的人为了利用阳光合成维生素D, 渐渐地有了较为白皙的皮肤。住在寒冷而干燥地区的人们长得矮胖,以便保存热量;住在干 燥而炎热地区的人们长得高瘦,以便使热量容易散发。 答案: Section A 很多人认为科技发现是灵光一闪,或戏剧化事件的产物:艾萨克·牛顿爵士在花园中注意到了苹果落地,从而发现了万有引力定律。很显然,这一观点并不正确。弗莱明爵士并不如传闻所言那样,看到一片奶酪上的霉菌,在当时当地就想到(发明)了抗生素盘尼西林。事实上,他做了九年之久的抗细菌物质的实验,终于才有了他的发现。发现和革新总是来自于勤勉的“试误”实验。革新和发明就像是足球赛,即使是最好的选手也会射不进球,他们射门受阻的次数远远大于射门得分的次数。 Section B Nature began a new experiment. Instead of adapting to a specific environment, man has the capacity to adapt himself to any specific environment. They spread throughout the globe, changing as they moved, until they became the most widely distributed species on the earth. Man adapted physically as well as culturally to the new surroundings into which he moved. People who lived near equator developed dark skin to protect themselves from strong sunlight; people who moved to colder climates developed light skin to take advantage of the sunlight for the synthesis of vitamin D; people in cold dry climates became stocky to conserve heat. People in hot dry climates tended to become tall and thin to dissipate heat.

(10 points) People have speculated for centuries about a future without work.Today is no different,with academics,writers,and activists once again 1 that technology is replacing human workers.

One Gallup poll found that 20 percent of Americans who have been unemployed for at least a year report having depression,double the rate for 7 Americans.

Today,the 15 of work may be a bit overblown. “Many jobs are boring,degrading,unhealthy,and a waste of human potential,” says John Danaher,a lecturer at the National University of Ireland in Galway. These days,because leisure time is relatively 16 for most workers,people use their free time to counterbalance the intellectual and emotional 17 of their jobs. “When I come home from a hard day’s work,I often feel 18 ,” Danaher says,adding,“In a world in which I don’t have to work,I might feel rather different”—perhaps different enough to throw himself 19 a hobby or a passion project with the intensity usually reserved for 20 matters.

东南大学英语语言文学专业考研经验

宏韬东大考研网 2014东南大学英语语言文学专业考研经验 现在有点空闲时间了,可以写点经验帖出来借大家参考。回想复习,初试,复试的经历不是很清晰了。但是想要告诉后来的同学们,希望可以有帮助。 记得是2007年的六月份决定了考研究生。相对于很多人来说应该比较晚了。考研是一定要选择学校的,当时选择上外,是因为这是英语领域很强的学校了,还有一个原因是大学在北京,不是很喜欢它,所以想去上海了。另外的原因是上外不考文学和语言学,这两门是我学得不好也很头疼的科目。我最喜欢翻译。更有一个重要的原因是这个论坛让我喜欢上了上外,喜欢这里的人们,他们很热情,善良,耐心。 买书是一件麻烦的事情,因为很多的书不能直接买到,是要预定的。而且还有书是买不到的,就像张培基的第一辑《英译中国现代散文选》。所以买书用了很多时间。我想如果在大城市里应该有很大的书店或者书城,就可以买到需要的书了。我的书不是一次买齐的,而是陆陆续续买回来的。书目是从这个论坛了解到的,所以心里很感谢学姐和师哥们。初试买的书有很多,数一数大概有十几本吧,我想有很多人买的应该更多吧。 英语 《汉英翻译基础教程》杨晓荣编著中国对外翻译出版公司(1,2,5,6,7,8)买了六本,还有7,8册答案书,所以是8本。很认真的看了7,8册,没有看1,2册,简单的看了5,6册。 《大学英汉翻译教程》王治奎山东大学出版社这本书是很容易买到的。 《大学英语语法与词汇》袁晓宁主编北京外语教学与研究出版社 等一些重要的参考书 法语 《新大学法语》(1)周林飞、李志清编高等教育出版社这不是我大学学习的课本,所以还是很认真的看了一遍,觉得内容比较多,有点难。 《大学法语考研必备》(世界图书出版公司)这本书是很好的,我很认真的把每一题都做了,看了两遍。 政治 《2007考研政治理论考试参考书》这本书很好买的,好好第看一遍很重要。 《政治理论基础过关2000题》认认真真的看了一遍,但是没有记住。 《2008全国硕士研究生入学考试用书--陈先奎政治考前大串讲》这本书很厚,不详细,建议不要买了。 《形势与政策》忘记了哪里出版的,我想任意的一本内容都是差不多的,讲的内容很多,很繁琐。但还是要好好看的。 还有一本《考研复习精编》,因为这是我报考的宏韬东大考研网的辅导班出的书,对我帮了很大的忙。 这就是我买的所有的书了,不是很多。但是我从小的时候就有认真看书的习惯,记得每次考试之前会把课本从头到尾认真看一遍。所以这几本书是认真看了的。

东南大学研究生一年级学术英语教科书答案chapter9

Unit 9 referencing 1.1 Pre-reading tasks Why do we have to reference? When you reference correctly you are demonstrating that you have read widely on a topic. You are also supporting your hypothesis with comments from expert authors. This lends credibility to your own work. Also, by correctly referencing, you allow the marker or reader to follow-up your refer ences and to check the validity of your arguments for themselves. This is an important part of the academic process as it leads to student accountability. How do we usually reference? (In-text citation and reference list) How do we create a reference list? When creating a reference list, the sources should be listed alphabetically by author’s surname, should be left justified, and the references should never be preceded by a bullet-point or number. Where the author is anonymous or unknown for any one source, insert that source in the alphabetical list using the title of the source instead of the author’s name. All sources should be listed together; there should not be separate lists for books versus journal articles versus electronic sources. The reference list should be on a separate page from the rest of the assignment and should be simply titled ‘References’ or ‘Literature Cited’ and the t itle should be in the same font and size as the other headings in your assignment. How many referencing styles do you know? (APA, MLA etc) 1.3.1 Differences between Science and MLA Science MLA Book reference order of publisher and place. (publisher, place) Punctuation mark. Information is segmented by comma. Publisher, place and year in blanket. Example: J. B. Carroll, Ed., Language, Thought and Reality, Selected Writings of Benjamin Lee Whorf (MIT Press, Cambridge, MA, 1956) 1. order of publisher and place. (place:publisher) Punctuation mark. Information is segmented by full stop. Example: McDonagh, Sean. Why are we Deaf to the Cry of the Earth. Dublin: Veritas, 2001. Journal reference 1. Order of first name and last name: first name. Last name 2. Order of year and page: Page (year) 3. Punctuation mark. 4. Example: N. Tang, On the equilibrium partial pressures of nitric acid and ammonia in the atmosphere. Atmos. Environ.14, 819-834 (1980). 1. Order of first name and last name: Last name, first name. 2. Order of year and page: (year):Page . 3. Punctuation mark 4. Example: Mann, Susan.
