The purpose of this paper is to study the proper curvature collineations of plane symmetric static spacetime in f(R) theory of gravity. We have taken the metrics of both constant and non-constant curvature and formulated the curvature vector fields by using vanishing Lie derivative and direct integration technique. Here, the solutions of the Einstein’s field equations (EFEs) for both cases involve inverse curvature terms which may cause an increase in gravity that justifies the accelerated expansion of the universe. It turns out that curvature collineations become Killing vector fields and therefore, proper curvature collineations do not exists in both the cases.
本文的目的是研究f(R)引力理论中平面对称静态时空的固有曲率共线。我们取了常曲率和非常曲率的度量,并利用消失李氏导数和直接积分技术构造了曲率向量场。在这里,两种情况下的爱因斯坦场方程(EFEs)的解都涉及到逆曲率项,这可能会导致引力的增加,从而证明宇宙的加速膨胀是正确的。结果表明,曲率共线变成了杀向量场,因此,在这两种情况下,适当的曲率共线都不存在。

United nations have defined Internet as a human right as it enables us to effectively share ideas. Even though it has revolutionized the way we live, access to it is dependent on socio economic factors, as many in the developing nations simply cannot afford to own a computer. The paper proposes ‘TextNet’ system which enables people to access Internet through SMS Technology. The proposed system provides offline access to information available over Internet and works solely on the SMS (Short Message Service). A user simply needs to send a request for information about any topic to a designated number, which is received at server and after fetching information from Internet; the server sends it back to user through SMS
联合国将互联网定义为一项人权,因为它使我们能够有效地分享思想。尽管它彻底改变了我们的生活方式,但能否使用它取决于社会经济因素,因为许多发展中国家根本买不起电脑。本文提出了“TextNet”系统,使人们能够通过短信技术访问互联网。所建议的系统提供对互联网上可用信息的离线访问,并且仅在SMS(短消息服务)上工作。用户只需要向指定的号码发送一个关于任何主题的信息请求,该请求由服务器接收,并从互联网获取信息;服务器通过SMS将其发送回用户

Chatbot is an intelligent conversational system that interacts with humans via natural languages, where natural language processing utilizes computational methods to learn, understand, and generate human language contents. The scope of this paper is restricted towards Chatbot. Accessing the required and right type of information from a website is a time-consuming process. In this paper a particular focus is placed on the academic organizations. Sometime an employee or an academic administration staff spends several hours to reply a query. To address this issue, this paper proposes two forms of Chatbots i.e. written and spoken. They provide user interaction and consultation regarding admission process, and other related information pertaining to an academy. This would be a quick way to acquire information without the need to traverse the entire website and is also applicable to any academic or educational websites, such as schools, colleges, universities, or any institution. Both Chatbots are implemented using artificial intelligence mark-up language (AIML).
聊天机器人是一种通过自然语言与人类交互的智能会话系统,其中自然语言处理利用计算方法来学习、理解和生成人类语言内容。本文的范围仅限于Chatbot。从网站上获取所需和正确类型的信息是一个耗时的过程。在本文中,一个特别的重点放在学术组织。有时,一名员工或学术管理人员会花几个小时来回答一个问题。为了解决这个问题,本文提出了两种形式的聊天机器人,即书面和口头。他们为用户提供有关录取过程的交互和咨询,以及与学院有关的其他相关信息。这将是一种获取信息的快速方法,而不需要遍历整个网站,也适用于任何学术或教育网站,如学校、学院、大学或任何机构。这两个聊天机器人都使用人工智能标记语言(AIML)实现。

A wireless hybrid network; integration of wireless ad hoc network and wireless infrastructure network is recognized as superior option for next generation wireless networks. Such network focuses to support of continuous transmission with strong Quality of Service (QoS). In hybrid networks, the way to guarantee quality of service (QoS) remains a hot problem, where it is observed that due to the direct adoption of QoS based reservation resource routing for MANET, hybrid networks inherit problems of resource reservation and invalid racing conditions. The article presents the working of two AdHoc routing protocols (DSDV and AODV+) in hybrid systems in relation with different network complexities. It is observed that both protocols performed indistinguishably to the extent of the throughput. For jitter, PLR and PDR, the AODV+ performed superior to DSDV; except for the intricacy situation of system, while DSDV performed ineffectively.
无线混合网络;无线自组织网络和无线基础设施网络的融合被认为是下一代无线网络的优越选择。这种网络以支持连续传输为重点,具有较强的服务质量(QoS)。在混合网络中,如何保证服务质量(QoS)一直是一个热点问题,研究发现,由于MANET直接采用基于QoS的预留资源路由,混合网络继承了资源预留和无效竞争条件的问题。本文介绍了两种AdHoc路由协议(DSDV和AODV+)在不同网络复杂程度的混合系统中的工作原理。可以观察到,对于吞吐量的程度,这两种协议的执行没有区别。对于抖动、PLR和PDR, AODV+优于DSDV;除了系统复杂的情况外,DSDV的性能不佳。

The yield and fibre traits of cotton are adversely influenced by moisture stress. Thus, it is great issue for cotton physiologists and breeders to develop water stress tolerable genotypes. In current research, 12 cultivars such as CRIS-134, CRIS-342, CIM-499, Sadori, CIM-506, Chandi, BH-160, Sindh-1, NIAB-78, CIM-496, CIM-534 and Bt-cotton (Australian origin) were screened for water stress tolerance with four replications in factorial design in Pakistan during 2010. Water stress caused significant reduction in all yield as well fibre traits. The genotypes also differed significantly for yield and fibre quality traits studied. The treatments x genotypes interactions were significant indicating that genotypes responded variably over stress environments suggesting that plant breeders can select the best performing genotypes for moisture deficit environments. Among genotypes screened, Sadori, CRIS-134,Chandi, CRIS-342,CIM-506 and Sindh-1 showed good performance due to minimum decline under stress conditions for majority of the traits. Hence, these cotton genotypes were identified as drought tolerant and can be further utilized in breeding programmes to develop new drought tolerant breeding material.
水分胁迫对棉花的产量和纤维性状有不利影响。因此,培育棉花耐水分胁迫基因型是棉花生理学家和育种家面临的重要课题。本研究于2010年在巴基斯坦对12个品种(crisi -134、crisi -342、CIM-499、Sadori、CIM-506、Chandi、bh160、Sindh-1、NIAB-78、CIM-496、CIM-534和bt棉(澳洲原产)进行了4个重复的水分胁迫抗性筛选。水分胁迫显著降低了作物的各项产量和纤维性状。各基因型在产量和纤维品质性状上也存在显著差异。不同基因型处理间相互作用显著,表明不同基因型对胁迫环境的响应不同,表明植物育种者可以在水分亏缺环境中选择表现最好的基因型。在筛选的基因型中,Sadori、crisi -134、Chandi、crisi -342、CIM-506和Sindh-1的大部分性状在胁迫条件下下降最小,表现良好。因此,这些棉花基因型被确定为耐旱品种,可以进一步用于育种计划,开发新的耐旱育种材料。

The treatments x genotypes interactions were significant indicating that genotypes responded variably over stress environments suggesting that plant breeders can select the best performing genotypes for moisture deficit environments. Among genotypes screened, Sadori, CRIS-134,Chandi, CRIS-342,CIM-506 and Sindh-1 showed good performance due to minimum decline under stress conditions for majority of the traits. Hence, these cotton genotypes were identified as drought tolerant and can be further utilized in breeding programmes to develop new drought tolerant breeding material.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"23 1","pages":"45-52"},"PeriodicalIF":0.0,"publicationDate":"2018-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89297262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prime focus of the research work presented herein is to investigate the applicability of eight intensity prediction equations to the available dataset for Khash, 2013, earthquake. To this end, data obtained for the earthquake is utilized for comparison with the intensity estimates using the intensity prediction relationships. The data comprises of both subjective as well as instrumental observations. The subjective data used in this study includes a survey conducted in the affected regions, questionnaire surveys through posts, email and telephone and online surveys, while the instrumental data includes the Peak Ground Acceleration (PGA) values recorded through accelerograms. The information gathered from the subjective data is used to estimate the damage which helped in assigning appropriate Modified Mercalli Intensity (MMI). Using Root Mean Square Error (RMSE), the prediction equations are ranked for future use in the seismic hazard assessment procedures. The comparison with the observed intensity has shown that the equations developed for California and Himalaya are in better agreement than the equations developed for Eastern Northern America, Central Eastern United States, Craton and entire India.
本文提出的研究工作的主要重点是研究8种烈度预测方程对2013年哈什地震可用数据集的适用性。为此,利用获得的地震数据与使用烈度预测关系的烈度估计进行比较。这些数据包括主观观测和仪器观测。本研究使用的主观数据包括在受灾地区进行的调查,通过邮寄、电子邮件、电话和在线调查进行的问卷调查,而仪器数据包括通过加速度计记录的峰值地面加速度(PGA)值。从主观数据中收集的信息用于估计损害,有助于确定适当的修正麦卡利强度(MMI)。利用均方根误差(RMSE)对预测方程进行排序,以便将来在地震危险性评估程序中使用。与观测强度的比较表明,加利福尼亚和喜马拉雅地区的方程比北美东部、美国中东部、克拉通和整个印度的方程更符合。
