second, cluster membership adapts at no additional cost; third, nodes within a cluster are not required to track the membership of other nodes in the Furthermore, SAF provides provably correct error bounds and allows the user to dynamically tune answer quality to answer queries in an energy and resource efficient In addition, we apply the AR models to solve the time synchronization problem from a novel perspective which is complementary to the well-studied clock synchronization problem [3,4] More precisely, we analyze the case in which a sensor node decides to skip one or more clock adjustments to save energy, or it is temporarily isolated, but still requires an accurate estimate of the We propose a provably correct clock method based on AR models, which returns a time estimate within a constant (tunable) error bound and error This method is highly adaptable and allows the sensor to decide how manyclock adjustments it can skip while maintaining the same time accuracy, thus saving In addition, we propose a suit of deterministic methods that reduce the time estimation error by at least a factor More precisely, we propose a provably correct deterministic clock reading method, called the DCR method, which exploits information regarding the sign of the clock deviation, and can be applied to reduce by half the frequency of the periodic clock adjustments, while maintaining the same error bound [3,4] This method is of both practical and theoretical In fact, it leads to a noticeable energy saving, and shows that a stronger but realistic clock model can lead to a refinement of the optimality bound for the maximum deviation of a clock that is periodically In addition, we propose a generalized version of the DCR method that enhances its accuracy depending on the clock stability, and a method that guarantees the monotonicity of the time values We analyze for the first time quorum system techniques in the context of sensor networks: we redesign them and show their benefits in terms of energy consumption [6] Quorum systems have the potential to save energy in sensor networks since they can reduce noticeably the amount of communication, improve the load balance among sensor nodes, and enhance the scalability of the However, previous quorum systems and quorum metrics, proposed for wired networks, are unsuitable for sensor networks since they do not address their properties and These observations have motivated us to redesigning quorum systems and their metrics, taking into account the limitations and characteristics of sensors (, transmission costs, limited energysource, physical radio broadcast), and the network More precisely, we redefine the following quorum metrics: load balance, access cost and quorum capacity, and devise some strategies based on some characteristics of sensor networks that reduce the amount of communication when designing quorum systems for sensor We apply these strategies to design a family of energy-efficient quorum systems with high In particular, we propose a quorum construction that reduces the quorum access cost, and propose an energy-efficient data diffusion protocol built on top of it that reduces the energy consumption by reducing the amount of transmissions and In addition, we analyze quorum systems in case of high node More precisely, we study the difficult problem of guaranteeing the intersection between two quorums in case nodes move continuously along unknown paths [7] We address this problem by defining a novel mobility model that provides a minimum set of constraints sufficient to derive strong data guarantees in highly mobile Also in this case, we show the unsuitability of previous quorum systems, and provide a condition which is necessary to guarantee data availability and atomic consistency under high node We propose a new classof quorum systems, called Mobile Dissemination (MD) quorums, suitable for highly mobile networks, and propose a quorum construction which is optimal with respect to the quorum size (, message transmissions) [7] Then, we apply the MD quorum system to implement a provably correct atomic read/write shared memory for mobile and sparse Bibliography [1] D Tulone, S M PAQ: Time series forecasting for approximate query answeringin sensor In P of the 3rd European Workshop on Wireless Sensor Networks, 21-37, Feb [2] D Tulone, S M An energy-efficient querying framework in sensor networks for detecting node Submitted to [3] D T On the feasibility of global time estimation under isolation conditions in wireless sensor To appear in A[4] D T A resource-efficient time estimation for wireless sensor In P of the 4th Workshop of Principles of Mobile Computing, 52-59, Oct [5] D T How efficiently and accurately can a process get the reference time?

一区期刊二期期刊

一区二区三区指的是地区,分别如下:一区包括北京、天津、河北、山西、辽宁、吉林、黑龙江、上海、江苏、浙江、安徽、福建、江西、山东、河南、湖北、湖南、广东、重庆、四川、陕西等21省(市)。二区包括内蒙古、广西、海南、贵州、云南、西藏、甘肃、青海、宁夏、新疆等10省(区)。分区是将全国各省、直辖市根据地理位置、交通便利程度等划分的几个区域,一区最便利,资费相应最低;三区最边远,资费相应最高;二区介于中间。SCI期刊的分区:一区二区三区四区是sci期刊的分区,sci期刊的分区有两种,一种是jcr的分区,另一个是中科院的分区,这两类分区很类似,都是分为四个区,分区的标准也都是期刊的影响因子,至于不同区的期刊的区别,很显然的区别就是这四个区是按照影响因子由高到低排序的。一区期刊是影响因子最高,学术价值最高,影响力最大的期刊,四区期刊就是四个区中影响因子最低的一类刊物。

作用不同:sci的作用是进行科学统计与科学评价;ei的作用是是供查阅工程技术领域文献的综合性情报检索刊物。

SCI期刊SCI(Science RealthIndex)是美国科学情报研究所出版的世界著名期刊文献检索工具。它包括数量、原因、化学、农业、林业、医学、生命科学、天文学、地理、环境、材料和工程技术等。自然科学各学科的核心期刊。工程指数(EI)发表于1884。它是美国工程信息公司(工程信息公司)出版的著名的工程技术综合检索工具。EI每月出版1期。1万3000至1万4000篇文章,摘要,摘要;主题索引和作者索引的每一个问题;年度和年度索引也被出版。扩展资料:EI和SCI的区别如下:1、创办不同:SCI由美国科学信息研究所在美国费城创办,是由美国科学信息研究所(ISI)1961年创办出版的引文数据库;EI是由美国工程师学会联合会于1884年创办的历史上最悠久的一部大型综合性检索工具。2、作用不同:SCI的作用是进行科学统计与科学评价;EI的作用是是供查阅工程技术领域文献的综合性情报检索刊物。3、属性不同:SCI偏向于自然科学、生物、医学类的,而EI偏向于机械工程、机电工程、船舶工程、制造技术等。4、出版时间不同:SCI每年出六期,现每期有 A、B、C、D、E、F六册;EI每月出版1期。参考资料:百度百科词条-科学引文索引百度百科词条-工程索引

I是科学引文索引,主要收录的是国际上理科方向的文章。EI也是偏向于理科方向,但它收录的是会议论文。国际上还有一个SSCI,这个是偏向于文科的检索系统,之后被引入到中国就成了CSSCI,即南大核心期刊。关于难度:都比较难,因为SCI、EI和CSSCI 的收录方向不同,所以比较难度不具有科学性。反正,都很难。关于认可度:SCI、EI是国际期刊,CSSCI是国内期刊,自然SCI和EI的认可度比较高,如果一篇文章能够被SCI和EI 双检索的话,就更好了。关于加分:很多人发文章是为了加分评职,根据我多年的经验来看,SCI加分最多,有的单位EI和SCI是平级加分,有的单位EI加分稍低,CSSCI的加分都低于国际期刊。

SCI(科学引文索引)、EI(工程索引)。SCI:美国《科学引文索引》(Science Citation Index, 简称 SCI )于1957 年由美国科学信息研究所(Institute for Scientific Information, 简称 ISI)在美国费城创办,是由美国科学信息研究所(ISI)1961 年创办出版的引文数据库。EI:工程索引(EI)是由美国工程师学会联合会于1884年创办的历史上最悠久的一部大型综合性检索工具。EI在全球的学术界、工程界、信息界中享有盛誉,是科技界共同认可的重要检索工具。扩展资料:EI每月出版1期,文摘3万至4万条。数据库每年新增500000条工程类文献,数据来自5100种工程类期刊、会议论文和技术报告,原始文献来自40余个国家,涉及的语言多达39种,其中3600种有文摘。年报道文献量16万余条。每期附有主题索引与作者索引;每年还另外出版年卷本和年度索引,年度索引还增加了作者单位索引。SCI:评价标准1976 年,ISI 在 SCI 基础上引出期刊引用报告(journal citation report,JCR),提供了一套统计数据,展示科学期刊被引用情况、发表论文数量以及论文的平均被引用情况。在 JCR 中可以计算出每种期刊的影响因子(Impact Factor,IF)。影响因子的高低,在一定程度上可以反应一个期刊的影响力。参考资料:百度百科---EI    百度百科-----SCI

SCI是科学引文索引。EI是工程索引。SCI,即《科学引文索引》,英文全称是Science Citation Index,是美国科学情报研究所出版的一部世界著名的期刊文献检索工具,通过其严格的选刊标准和评估程序来挑选刊源。其检索对象主要是自然科学。EI即《工程索引》, 其不收录基础理论研究文章。系美国工程信息公司出版的一个著名工程技术类综合检索工具。SCI和EI都是刊物中等级较高的刊物,对于论文的收取来说自然是比较严格的,并且这些对于论文的投稿发表对于职称的晋升来说也是有很大帮助的。扩展资料:SCI评价的引入影响:1、不可否认,SCI评价的引入对鼓励科研人员瞄准国际一流,促进我国科研水平有过正面的引导提升作用。然而,随着时间推移,由此带来的负面后果也凸显。2、多而不精,引用率不高现象已经到了非重视不可的地步。一些学校领导习惯于比“SCI”,仿佛有了几篇顶级SCI,学校整体水平就提升了。对推动学术界整体浮躁起到催化剂作用。3、高校行政化管理将评判学者水平的权力交给一些行政人员。行政人员对学术不很了解,常常会把评判简单化、数字化,不会仔细考量某项具体成果在同行当中的切实影响。参考资料:百度百科:SCI  百度百科:EI

sci更好些。ei和sci是两种国际权威的检索工具,发表起来难度都很大,一般作者自己发表很难成功,想要成功发表这类论文,必须和专业的论文机构合作,有他们帮助翻译,润色论文,提升论文质量,投稿成功率可以高一些,需要发表ei或者sci论文的作者可以联系在线学术顾问。sci比ei更具有说服力。

期刊增刊算期刊吗

属于吧

也是核心的。

正刊是指期刊正常出版的期刊,比如月刊,每月出一本,连续的,就是正刊。一般封面上都注明1期、2期、3期…… 总第xx期等等。增刊和专刊,都是临时性出的,是在正刊之外的。不属于正常连续出版的期数里面,一般增刊或专刊都会在封面上注明“增刊”“专刊”字样,也有的注明“Z1”“Z2”,没有注明是第几期。正常情况下,增刊的内容是不被期刊网收录的。不过最近几年,学术刊物的增刊和专刊不算分了,有些编辑部出增刊和专刊的时候,就故意在封面上写上第xx期,不注明或者在极其不容易发现的地方注明“增刊”“专刊”字样,以迷惑作者和读者,甚至还有的增刊内容也上了期刊网,这样的更具有迷惑性,所以作者在发表文章前,一定要弄清楚是不是增刊。
