Computational grids have the potential for solving large scale scientific problems using heterogeneous and geographically distributed resources. Before this potential is realized, there are several technical overheads that must be overcome. This paper introduces PRAG — a resource allocation technique that is pre-emptive in nature. The critical problem for grid users is efficient allocation of resources...
Cloud computing is a service where storage and computing resources can be accessed on subscription basis. Cloud computing is powered by the concept of virtualization technology. The virtual machines (VM) are hosted in servers so that user's requests are serviced in an optimal manner. The process of moving a running virtual machine or application between different physical machines without disconnecting...
Fault tolerance in cloud computing is a grand challenge problem now a days. The main fault tolerance issues in cloud computing are detection and recovery. To combat with these problems, many fault tolerance techniques have been designed to reduce the faults. In this paper, we have proposed a Virtualization and Fault Tolerance (VFT) technique to reduce the service time and to increase the system availability...
Generation and propagation of automatic alerts from a Hospital Information Management System (HIMS) is a non-trivial problem. Inability to generate an alert in a genuine case is considered as a more serious shortcoming than generating false alerts. Due to this, medical instruments and HIMS systems tend to generate large number of false alerts. This reduces the credibility of the alert system and stake...
Cloud computing is the current technology used for sharing and accessing resources via Internet. It provides a scalable and cost effective environment. Large number of servers in the datacenters leads to huge consumption of power in the cloud computing scenario. Optimization of power consumption is a key challenge for effectively operating a datacenter. Power consumption can be regulated by using...
In this study, 3-D structures of Harpin protein (Pectobacterium carotovorum), Single-stranded DNA binding protein (Pseudomonas aeruginosa), and R2.L1aJI (Campylobacter conisus 13826) has been modelled. For modelling, template selection is done by BLASTp search. For target template alignment, ClustalW server is used and then comparative modelling was done by Modeller9.10. Validation of models was done...
Voice over Internet Protocol (Voice over IP, VoIP) is one of a family of communication protocols, and transmission technologies. It is used for delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks. Session Initiation Protocol (SIP) is a signaling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet...
Importance of print media in daily life is remarkable. Though the popularity of electronic media has increased considerably, print media still retains relevance in various areas. Mobile devices are nowadays used as common means of consuming electronic media. Recent surveys on mobile application usage patterns reveal that many users utilize mobile phones for reading articles, analyzing reports and...
Remote vehicle monitoring system keeps track of vehicle and also monitor the fleet level of the vehicle status. Here two problems are dealt with. First one is the anywhere any time monitoring of the vehicle status cannot be done through manual monitoring and the second one is the system behavior change according to user changes. The novelty of the proposed approach is twofold. First our proposal allows...
The use of the web increases day-by-day. User visits the pages and gives the feedback about the content of the web page. If a user is paying attention on the content of a web page, he spends more time in comparison to the other pages. User chooses some click on the particular page for search query content. These clicks are stored on server log file for measuring the web page importance on the basis...
Nowadays, use of web has increased. User search a web corresponds to a query. Search engine provide indexed result for the users. Clickstream analysis is a new approach for web page importance calculation. User uses some clicks on the results according to the search result. These clicks are stored on server log file. Server log file store the order sequence of user clicks after that these clicks can...
Interactive Learning Environment has proven to be an effective solution for overpowering the limits of traditional one-to-many teaching. However, these environments require accurate representation of knowledge about learner to provide suitable guidance. Based on the behavior and performance, the traces of learners are captured and categorized to provide appropriate guidance in the learning environment...
Deploying Java applications to the cloud with access rights to the local client's file-system involves modification of the Java application code to use non-standard APIs for client's filesystem access. With the steady migration of existing technologies towards a web-aware implementation, this paper presents the file access sub-system of a potential WebJDK. WebJDK is designed to provide an implementation...
