Decentralized proactive caching and coded delivery is studied in a content delivery network, where each user is equipped with a cache memory, not necessarily of equal capacity. Cache memories are filled in advance during the off-peak traffic period in a decentralized manner, i.e., without the knowledge of the number of active users, their identities, or their particular demands. User demands are revealed...
Mobile devices have been helping to empower underserved communities around the world. From bringing information on health and farming to substituting expensive devices, cellular phones and apps have proved to be powerful tools in poverty alleviation and disaster relief. The Mobile Lab at Santa Clara University focuses on developing mobile solutions for social benefit and, in this paper, we describe...
Provision of reliable traffic data could cause a reduction of the traffic problem. In a previous paper, the authors developed the core of RIMAC, an information system that allows the introduction of new and reliable sources of information from camcorders, traffic lights or mobile phones. With these new data sources, RIMAC is able to provide many more realistic reports. This paper describes the development...
In this paper, a hybrid broadcast broadband TV (HbbTV) test system with the automatic testing subsystem is proposed. The proposed system is based on Node.js framework with SQLite database on the backend side and Polymer framework on the front-end side. The paper covers basic testing metodology and design process with the emphasis on the implementation and testing.
Due to the high cost and high power consumption problem of the present smart home server, we designed and implemented a home server based on embedded system, mainly developed by ARM11 for a hardware platform, Linux system for operating system, SQLite database and BOA server for a software platform. The home server has successfully implemented the network communication, SQLite database peration and...
Despite their proliferation as a dominant computing paradigm, cloud computing systems lack effective mechanisms to manage their vast amounts of resources efficiently. Resources are stranded and fragmented, ultimately limiting cloud systems' applicability to large classes of critical applications that pose non-moderate resource demands. Eliminating current technological barriers of actual fluidity...
The technology of Intelligence agent is an application of artificial intelligence, as well as a hot topic of the IT circle. A new system architecture related to intelligent agent technology is proposed based on the characteristics of cloud computing. The architecture is divided into four layers: user layer, agent layer, application layer and data layer. The paper analyses the key technology of intelligent...
Contemporary e-learning solutions frequently used in educational institutions and companies are based on learning management systems (LMS). As they usually represent standalone solutions, tests (quizzes) represent the only interactive tool offered for evaluating the learner knowledge. Regardless todays LMS support almost all of question types, learner — system interaction is not at satisfactory level...
Data visualizations have become an integral role for management system. It not only allows users to witness, explore and understand large amounts of information, but also convey information more directly expressed. This paper presents how to use JavaScript third-party library such as Flot and D3.js for collection, analysis, processing and visualization of data by using Ajax.
In this demo, we present Coagmento 2.0, a Web-based, open-source platform that provides support for one working in individual or group projects spanning multiple sessions that involve looking for, collecting, and synthesizing information. The system also provides a highly customizable platform for researchers who want to investigate individual and group information seeking behaviors in a lab or a...
With the expanding application of the two-dimensional barcode, the harmfulness of malicious URLs is much more serious. For preventing malicious URLs of two-dimensional barcode, this paper proposes a detection method -- H-SBH which is utilizing hash function. Firstly, the detection system extracts eigenvalues of malicious and benign URLs by H-SBH, then builds black and white lists library based on...
Gathering and analyzing statistic information is essential for every college or university, which cares about their students. This paper aims at giving theoretical overview of modern web page development and statistics gathering methods, analyzing present state of TUKE and designs a new statistics system, where emphasis is placed primarily on comfortable work of students with the system.
RESTful API documentation is expensive to produce and maintain due to the lack of reusable tools and automated solutions. Most RESTful APIs are documented manually and the API developers are responsible for keeping the documentation up to date as the API evolves making the process both costly and error-prone. In this paper we introduce a novel technique using an HTTP proxy server that can be used...
Early detection of breast cancer plays an important role in survival of the patients. As smart phones have a massive impact on our lifestyle, we are seeking to decrease the time gap of onset and detection of breast cancer using a mobile phone app. In this paper, we discuss a web-based software application platform that can be used by any patient on their smart phone to automatically score the risk...
The boundary devices, such as routers, firewalls, proxies, and domain controllers, etc., are continuously generating logs showing the behaviors of the internal and external users, the working state of the network as well as the devices themselves. To rapidly and efficiently analyze these logs makes great sense in terms of security and reliability. However, it is a challenging task due to the fact...
This paper presents a novel relational database architecture aimed to visual objects classification and retrieval. The framework is based on the bag-of-features image representation model combined with the Support Vector Machine classification and is integrated in a Microsoft SQL Server database.
This document represents a client server based application designed for the purpose of artefact recognition in a museum, based on photos made with the help of a mobile phone. Image recognition was conducted with the help of SURF (Speeded Up Robust Features) algorithm. Server was implemented with the usage of Netty library. Because of the parallel approach used both in the classification part and during...
The article describes proven methods for MS SQL Server Express which automatically keep the latest data in the primary database, while older data are transferred into dynamically created databases. The system was deployed in Třinecké Železárny a. s. where the data older than 30 days is kept in the primary database, and older data is transferred into databases that were dynamically created for each...
