Wikipedia is one of the most popular information platforms on the Internet. The user access pattern to Wikipedia pages depends on their relevance in the current worldwide social discourse. We use publically available statistics about the top-1000 most popular pages on each day to estimate the efficiency of caches for support of the platform. While the data volumes are moderate, the main goal of Wikipedia...
Geo-tweet visualization help users know the events that is happening over the space and time from the tweets or wikipedia while they click on the specified location for a 3D based tag visualization. Normal events are detected by system which happens anywhere or anytime using machine learning algorithm and special events are also extracted by comparing current situation to normal regularities. Generally,...
In modern data centers a large amount of energy can be saved by intelligently distributing load on the available servers and transferring idle nodes into low energy modes. Distributing load leads to a more energy-efficient usage of the servers within a server farm. Additionally, the use of energy saving modes like suspend to main memory can decrease the energy consumption dramatically. The selection...
As "working with a browser" continues to gain acceptance, an emerging strategy adopted by software companies is to provide a Web version of their applications previously developed in a desktop environment. This article introduces a desktop application service framework that enables a Web server to host desktop applications and supports accessing these applications through a browser. The...
Workload burstiness and spikes are among the main reasons for service disruptions and decrease in the Quality-of-Service (QoS) of online services. They are hurdles that complicate autonomic resource management of data enters. In this paper, we review the state-of-the-art in online identification of workload spikes and quantifying burstiness. The applicability of some of the proposed techniques is...
This article aims at evaluating the interest of the Wicri network, a network of semantic wikis, both as a reservoir of curation rules allowing to enrich corpora metadata and as a tool for parameterizing and supporting of instructions for the creation of corpora exploration servers. Starting, from the analysis of a bibliographic corpus extracted from different documentary databases, the experiments...
The high resolution and widescreen mobile devices have tremendous applications in our daily lives. In this paper, we demonstrate a specific bi-screen video sharing application called WeWatch that a high resolution video is played across screens of two mobile devices. It helps users to enhance their watching experience on the Android system. In order to efficiently use idle mobile devices, we develop...
Accurate understanding of workloads is key to efficient cloud resource management as well as to the design of large-scale applications. We analyze and model the workload of Wikipedia, one of the world's largest web sites. With descriptive statistics, time-series analysis, and polynomial splines, we study the trend and seasonality of the workload, its evolution over the years, and also investigate...
In this study, build interactive location database intelligent video car recorder system. Video automotive logger system was established in the iOS intelligent mobile devices (iPhone). The video car recorder system can be record the current driving conditions, display the current location on the map, and upload it to the location database. Location database is constructed by a network server, MySQL,...
Virtualization has brought the revolution of utilizing computing elements, and also incurred the trends of cloud computing with distributed data centers built for enterprises. Recently, the network virtualization has become an issue for decreasing the cost and adding the flexibility of networking inside either the service platform or the infrastructure. Hence, research and education demands for testing...
We study the problem of maximizing the average hourly profit earned by a Software-as-a-Service (SaaS) provider who runs a software service on behalf of a customer using servers rented from an Infrastructure-as-a-Service (IaaS) provider. The SaaS provider earns a fee per successful transaction and incurs costs pro-portional to the number of server-hours it uses. A number of resource allocation policies...
Advancements in robotics have led to an evergrowing repertoire of software capabilities (e.g., recognition, mapping, and object manipulation). However, robotic capabilities grow, the complexity of operating and interacting with such robots increases (such as through speech, gesture, scripting, or programming). Language-based communication can offer users the ability to work with physically and computationally...
Many power management solutions are adapted for Cluster system. But the solutions are quite complicated and hard to adapt it for the system. In this paper, the simple algorithm and policy for the user in cluster system are introduced. This policy is based on system load and time and operates dynamically according to the policy. The controllable items are CPU frequency and system state from ACPI because...
Because of the variety of types of collaboration services used in enterprises today, there is difficulty in integrating related work threads from different collaboration environments. Each collaboration tool differs in storage model, APIs, content organization, content addressing, content formats, user authentication, and user interface. Nevertheless users prefer to be able to choose which collaboration...
Over the past decade the computing landscape changed dramatically as devices became ubiquitous, network-connected, and ready to communicate. As the landscape changed, the way in which we design and build software changed as well: The distributed application (one that involves multiple processes and devices) became the natural way we build systems, while the standalone desktop application became nearly...
Adessowiki is a collaborative environment for teaching and research in image processing. Adessowiki is composed of a collection of collaborative web pages in the form of a wiki. The articles of this wiki can embed programming code that will be executed on the server when the page is rendered, incorporating the results as figures, texts and tables on the document. The integrated collaborative environment...
Health Information Systems (HIS) has become more complex and complicate to manage and maintain their secure operations. Many kinds of information security breaches and unintended information disclosures of confidential patient information have reported to warn the important security issues of HIS. Integrating of security considerations for developing complex HIS is emergent to provide a secure system...
This paper presents a novel method of creating synchronized interactive TV applications using Quick Response (QR) code, where QR code is used to tag the broadcasted TV content. The QR code is decoded at the receiver side to communicate with an Internet server for interactivity. The proposed technique can be used for both classical analog TV and digital TV. The method described here can also be applied...
The Hive-Mind Space (HMS) model has been proposed to support distributed multidisciplinary design teams' collaboration and to tackle co-evolution of systems and users. The evolving design problems that cannot be predicted at design time require systems that have enough flexibility and tailorability to cope with emergent unexpected requirements. This paper presents MikiWiki, a prototype and meta-design...
Mobile devices are emerging with multiple interfaces with diverse access technologies. Simultaneously use multiple interfaces can bring lots of benefits to users. However, current TCP fails to support to simultaneously use multiple interfaces. Thus Multi-Path TCP is proposed to overcome the limitation. But MPTCP itself cannot provide mobility support, which may impose mobility restriction on mobile...
