This paper introduces a new trust management system (TMS) for the cloud computing domain. The wide majority of these systems do not fulfill the requirements of today's cloud environments which are characterized by heterogeneity in providers, capabilities and users. As such, they are limited to few aspects of trust. In fact, they are bound to a single function or a direct interaction with the cloud...
In this paper we have proposed an smart health service for victims in emergency scenario to allow the victims to interconnect without the conventional infrastructure. This service is provided using DTN architecture. By this system architecture, identification of injured people will be easy as it will provide information about the seriousness of the condition of the affected person, so that rescue...
Hadoop is a Java-based programming framework used by enterprises for management and analysis of large scale data originating from heterogeneous sources. To support the analysis of large scale data, different SQL-on-Hadoop systems are being utilized due to their ease of use for the people familiar with SQL. This study performs a comparative analysis of the SQL-on-Hadoop systems by comparing their performance...

This work presents the design, implementation, and evaluation of a learning platform that addresses two main objectives: first it provides and on-line quiz tool for students which can be used as a complementary learning approach to the classroom courses. Secondly, this tool performs a detailed analysis of learners use, considering not only the number of mistakes students have made but also the student...
This paper presents an adaptation of the Brousseau method. The concepts of didactic variations and interactions are introduced by using didactic and a-didactic situations. With the main aim of guaranteeing alumni improvement and evaluation processes, a case study application was development founded on a cloud architecture, which is also based in previous research, curricular organization and interaction...
Big data is data that exceeds the processing capacity of traditional database systems. The data is too voluminous, moves too fast, or is impossible to be managed by the structures of existing database architectures. Hence there must be an alternative way to process these data. This paper outlines the fundamental aspects of Big Data along with its opportunities and challenges. The paper builds on some...
Personalized mobile applications involve deploying the existing technologies to accommodate the differences between individuals. The existing applications have undertaken with the price and the location factors in mind. They show the same results regardless the personal special needs of consumers. The realization of the next generation of personalized systems will be a challenging task. For our research...
Students may seek information for various reasons such as to understand a specific subject matter or to conduct a research. In this digital age, they may not have a problem to find information. However, they are having problem to find scholarly information that suits their learning needs. This is because they are having difficulties to find the scholarly information that suitable for their learning...
At present, there are various courses and complicated course relationship in universities, which is not good for students to make rational course arrangement. To address this, course relationship network system (CRNS) is implemented. It proposes a marked traversal algorithm based on depth-first approach which helps to show the relationship between courses with a multilevel graph. Besides, all reasonable...
The Database Management System (DBMS) used to be a commodity software component, with well known standard interfaces and semantics. However, the performance, scalability and reliability expectations being placed on DBMS have increased the demand for a variety of add-ons, that augment the functionality of the database in a wide range of deployment scenarios, offering support for features such as clustering,...
In this paper we present the methodology for word sense disambiguation based on domain information. Domain is a set of words in which there is a strong semantic relation among the words. The words in the sentence contribute to determine the domain of the sentence. The availability of WordNet domains makes the domain-oriented text analysis possible. The domain of the target word can be fixed based...
In this paper, a new on-line signature verification system using neural network is presented. The proposed system is based-on a newly developed Spatio-Temporal Artificial Neuron (SPAN), which is well adapted for the verification of Spatio-Temporal patterns. In this model, the strokes of a signature generated by a digitizing tablet is presented in form of a sequence of spikes corresponding to displacement...
This paper provides an overview of work being done in the EntryPoint project, which is examining the first course work in computing degrees. A key goal of this project is to move away from the traditional CS1/CS2 programming courses as the start of a computing degree. In addition, the project team is looking at how these ideas might be extended to BSSE degree programs. As such, this paper will discuss...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
In recent years, organizations have been shifting focus to their core business competencies, and reducing total cost of ownership (TCO) associated with training and management of their IT infrastructure. In the same motif, organizations are establishing security and survivability frameworks as an integral part of their business strategy so as to provide an acceptable quality-of-service for their clients...
Currently, robots are being used as teaching tools and can be found in K-12 and college classrooms. The primary appeal associated with employing robots is that they tend to capture the attention of the target audience and thereby facilitate the learning process. While there are numerous robotic kits on the market today, few can be used to teach both high-level concepts in computer science and engineering...
Database dependencies are first-order sentences describing the semantics of databases. Decision problems concerning dependencies divide into local problem, such as whether a set of dependencies logically implies another dependency, and global problems, such as whether a set of dependencies is redundant. In this paper we investigate global problems, that of recognizing properties of sets of dependencies...
