In this paper we present a reference architecture for ETL stages of EDM and LA that works with different data formats and different extraction sites, ensuring privacy and making easier for new participants to enter into the process without demanding more computing power. Considering scenarios with a multitude of virtual environments hosting educational activities, accessible through a common infrastructure,...
Mobile device features such as camera and other sensors are evolving rapidly nowadays. Supported by a reliable communications network, it raises new methods in information retrieval. Mobile devices can capture an image with its camera and pass it to the retrieval systems to get the information needed. This system, called Mobile Content-Based Image Retrieval (MCBIR), generally consists of two parts:...
This paper addresses the problem of automatically inferring personality traits of people talking to a camera. As in many other computer vision problems, Convolutional Neural Networks (CNN) models have shown impressive results. However, despite of the success in terms of performance, it is unknown what internal representation emerges in the CNN. This paper presents a deep study on understanding why...
Computer architectures continue to develop rapidly towards massively parallel and heterogeneous systems. Thus, easily extensible yet highly efficient parallelization approaches for a variety of platforms are urgently needed. In this paper, we present SWhybrid, a hybrid computing framework for large-scale biological sequence database search on heterogeneous computing environments with multi-core or...
Architecture of database servers is one of the important parameters in the performance of web applications. In this paper, a model is proposed for guiding Postgre SQL database server sizing for concurrent users. Coloured Petri-nets are chosen to represent the model that brings out need to change the deployment architecture when the current architecture may not suffice. The focus of the proposed model...
Several applications in numerical scientific computing process sparse matrices with either a regular or irregular structure. The very large size of these matrices requires to use compressing formats and target parallel/distributed architectures in order to reduce both space complexity and processing time. The optimal compression format (OCF) of such matrices may in fact vary according to both the...
Data-driven research is increasingly ubiquitous and data itself is a defining asset for researchers, particularly in the computational social sciences and humanities. Entire careers and research communities are built around valuable, proprietary or sensitive datasets. However, many existing computation resources fail to support secure and cost-effective storage of data while also enabling secure and...
The main purpose of transfer learning is to resolve the problem of different data distribution, generally, when the training samples of source domain are different from the training samples of the target domain. Prediction of salient areas in natural video suffers from the lack of large video benchmarks with human gaze fixations. Different databases only provide dozens up to one or two hundred of...
There has been a recent push in the database community towards supporting real-time analytical queries (OLAP) while sustaining a large volume of fine-grained updates (OLTP). Supporting these types of workloads require both an efficient data storage layer as well as a distributed architecture. In this demo, we address the latter point with our Distributed Lineage-based Data Store (DL-Store), which...
Competition is always a good thing in IT world. It forces us to do our best. Nowadays, in the area of cloud computing, it is at the peak between the larger number of cloud users and cloud providers who view for the opportunity to use and provide services. Competition among cloud users means the price of cloud services never fall very low and between cloud providers mean the price of services never...
The current operation and development of National Defense M&S (Modeling & Simulation) virtual test application runs by FOM (Federation Object Model) type through HLA/RTI during simulation to interchange data. Simulation data interchanged by this method is one-shot data and won't be stored persistently. However, FOM typed data is in need of analysis, processing and reusability for the purpose...
Geographical Information Systems provide versatile information with physical locational perspective. Due to their inherent advantages and features, such systems are used almost by every organization however small or large it may be and even by individuals for various purposes. This paper presents a distributed cloud computing based GIS solution for electrical power utility asset management. License...
Many Organizations depend on Web Applications for performing various activities and stores the collected details in the database. Testing of the database is done to ensure the correctness for the design and working of the database. This paper performs testing of database design for the application using the Entity Relationship diagram for various components used in the database, the model is generated...
Nowadays there are already a multitude of various wearable devices, and more wearables are expected to come onto the market in the next few years. Much of the current research in wearable computing has fallen into two basic categories, device-centered and application-centered, which are however dedicated to specific applications, and without the flexibility and scalability sufficient to support more...
Heterogeneous cloud provides a feasible and attractive kind of infrastructure to the cloud applications which want to obtain high performance, availability or profit. Meanwhile, the cloud providers consider heterogeneous cloud as an ideal form to manage their computing resource since it can improve the utilization of their computing resources and extend the computing power of an individual provider...
This paper aims at the development of a cloud services provisioning framework by developing a dynamic priority job scheduler cum load-balancer for the cloud. The main motive of this paper is to provide a means of managing the job requests in a flexible and cost-effective way, both for the customer and the cloud service provider. In order to make the cloud scalable and adaptable to the changing needs...
This paper presents a proof-of-concept for a modular SystemC SIL (Software-in-the-Loop) simulation environment, using a blackboard-like architecture. The proposed SIL framework integrates embedded control software with simulators developed in SystemC/SystemC-AMS or external tools, like MATLAB. The environment has been validated by a heating application for a professional printer, as example of an...
Sequence analysis plays critical role in bioinformatics, and most applications of which have compute intensive kernels consuming over 70% of total execution time. By exploiting the compute intensive execution stages of popular sequence analysis applications, we present and evaluate a VLSI architecture with a focus on those that target at biological sequences directly, including pairwise alignment,...
The rapid development of Intelligent Transport Systems has created new objectives and requirements for traffic simulation models. The development of visualization, procedural modeling, decision support requirements mean that simulation models need to satisfy different requirements. The chapter presents methods and tools to create distribute, integrated and interactive transport simulations, to enable...
This work is based on two major areas, the Multiview Service Oriented Architecture and the combination between the computing cloud and MVSOA. Thus, it is suggested to extend firstly the service oriented architecture (SOA) into an architecture called MVSOA by adding two components, the Multiview service generator, whose role is to transform the classic service into Multiview service, and the data base,...
