USA-Kina flytta om klimatförändringar som är kritiska till Asien En uppsättning rapporter av den mellanstatliga panelen för klimatförändringar (IPCC), sist som släpptes den 2 November, 2014, sätter scenen för regeringar att förnya sina ansträngningar på frågan genom ambitiösa åtaganden för ett heltäckande klimatavtal i Paris i December 2015.
In Communication system, the system capacity and performance are adversely affected and degraded by interference. Hence, power control plays a prominent role in an interference-limited system, which increases the efficiency by mitigating the adjacent and co-Channel interference in the system. In this paper, primarily power control is said to be used in maintaining the acceptable Carrier to Interference Ratio (CIR) by meeting some Quality of service (QoS) requirements Objective function that is defined as maximum channel capacity in a power constraint scenario. The signals in a radio channel undergo different propagation effects like reflection, refraction, scattering and shadowing. Hence, the distribution of users across subcarrier groups as well as their transmission powers within a given cell has a significant effect on how users and power are accordingly distributed elsewhere in the network to maximize the capacity of the system thereby enhancing its performance
Exact Data sources consumer data from national database with approximately 210 million names, postal addresses, and telephone numbers, with approximately 700 selects, originating from over 2,000 different sources. Exact Data overlays its permission compliant, opt-in email address database from over 100 sources on that national database, to make what we believe is the best, most accurate and up to date multi-channel consumer database on the market. The database is compared to the USPS National Change of Address file every 60-days, and updated as necessary. And 15 to 20 million new email addresses are acquired each month, a rigorous, proprietary hygiene process is performed, and approximately 10%, or 1.5 to 2.0 million new email addresses, are appended to the national database.
- In this paper, we will enlist the process of extracting template from heterogeneous Web Pages. Extracting structured information from semi-structured machine readable web pages automatically plays a major role these days, so some websites are using common templates with contents to populate the data for good productivity, Where WWW is the major resource for extracting the information. The problem here is for machines, the templates in the web pages are considered to be harmful since they degrade the performance of web applications due to irrelevant terms in the Template. As a result, the performance of the entire system degrades. Template Detection technique can be used to improve the performance of search engine as well as for classification of web documents. In this paper, we present algorithms to extract templates from a very large number of web pages that are getting generated from heterogeneous templates. Using the similarity of template structures in the documen
Cloud computing is the apt technology for the decade. It allows user to store large amount of data in cloud storage and use as and when required, from any part of the world, via any terminal equipment. While Cloud services offer flexibility, scalability and economies of scale, there have been commensurate concerns about security. On the similar terms, we have chosen to make use of a combination of authentication technique and key exchange algorithm blended with an encryption algorithm. In this project, we have proposed to make use of 3DES algorithm which is a well-known symmetric cryptosystem and is widely used for secure data transmission, along with that we will blend it with Random Key Generator and Graphical Password to add an extra security measure. This proposed architecture of three way mechanism and the use of symmetric method of encryption make it tough for hackers to crack the security system, thereby protecting data stored in cloud.
Rapid and extensive modifications of land use /land cover due to accelerated human activities have been a major cause of global environmental change in the past three centuries. During the past 20 years, humans changed these landscapes to meet the growing demand for food, fodder, timber, fiber and fuel more rapidly and extensively than in any comparable period of time.
This paper presents Computational Fluid Dynamics (CFD) analysis of Pelton turbine of Khimti Hydropower in Nepal. The purpose of CFD analysis is to determine torque generated by the turbine and pressure distributions in bucket for further work on fatigue analysis. The CFD analysis is carried out on model size Pelton runner reduced at 1:3.5 scale to minimize computational cost and time. The operating conditions for model size runner is selected in accordance with IEC 60193 and IEC 1116. The paper describes the methods used for CFD analysis using ANSYS CFX software. 3 buckets are used to predict the flow behavior of complete Pelton turbine. k-ε and SST turbulence model with interphase transfer method as free surface and mixture model is compared in the paper. The pressure distribution is found maximum at bucket tip and runner Pitch Circle Diameter (PCD). The torque generated by the middle bucket is replicated over time to determine total torque generated by Pelton turbine.
Gray level Slicing is to highlight a specific range of gray values. Power Adaptation methods are presented for gray level slicing approaches. Power Adaptation methods aims in optimization of the resulting bit error rate by gray level slicing without preserving background and gray level slicing with background. This paper gives us an achievable increase in the proposed method rather than the conventional method with a better quality and the bit error rate is also optimized in proposed method rather than the former method with acceptable quality.
As the world runs fast, its our duty to run with the world compensating its speed. There is an urge to prove everyone unique. Hence time management play a worthless role in the daily work of a person. At morning it is a herculean task to wake up from the bed. “Let me sleep for some more time” is the first slogan of everyone every morning. But feeling guilty for not waking up in the morning is also encountered in several cases. In this paper we propose a novel “Murderer Algorithm” based automatic waking up system that helps to wake up every morning. The uniqueness of the system is to make the person in the bed to wakeup and get away from the bed. The device employs simple capacitive touch sensor to sense the presence of a person and also a brig
