With the rapid increase in data and its complexity of configuration and deployment bring a new challenge to the research community. In this scenario, automatic Hadoop cluster deployment and management tool provide a new horizon which plays a vital role in resource and packet management in distributed environment. This paper describes a low-cost Automatic Hadoop Cluster Deployment and Management tool...
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...
Recent studies have shown that attackers can force deep learning models to misclassify so-called “adversarial examples:” maliciously generated images formed by making imperceptible modifications to pixel values. With growing interest in deep learning for security applications, it is important for security experts and users of machine learning to recognize how learning systems may be attacked. Due...
With the growth of online services, a large amount of files have been generated by users or by the service itself. To make it easier to service users with different network environments and devices, online services usually keep different versions of the same file with various sizes. For users with high speed network and top of the line displays, a large size file with high precision can be supplied...
This paper presents a solution for establishing communication with Icecast and Shoutcast audio broadcasting servers. Web radio station is implemented, which means that is possible to broadcast an audio content from the local computer through Shoutcast and Icecast servers. Also, audio player is implemented for both local files, as well as web radio using FFmpeg libraries for audio package manipulation...
Cross Site Scripting (XSS) vulnerability acts as one of the chief widespread security issues in web applications. By reviewing the literature pertaining to XSS vulnerability, it has been found that many investigations have directed their energy only on XSS vulnerability detection, but not many studies have concentrated on removing XSS vulnerability. This paper embed the removal stage of XSS vulnerability...
Principles of the organization of the new network service intended for protected queries processing in the distributed information systems oriented on operation in multi-server network structures are considered. The use of the service for the pipeline queries processing in a chain of servers is described.
As the Internet of Things has emerged, it has become possible to develop applications and services through various types of input / output using things as well as various graphic displays. In view of the development of such interfaces, a distributed user interface (DUI) is emerging in which a plurality of devices are simultaneously used to utilize one application service. In order to activate a DUI-based...
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...
Knights Landing (KNL) is the code name for the second-generation Intel Xeon Phi product family. KNL has generated significant interest in the data analysis and machine learning communities because its new many-core architecture targets both of these workloads. The KNL many-core vector processor design enables it to exploit much higher levels of parallelism. At the Lincoln Laboratory Supercomputing...
Inter-process communication (IPC) is one of the crucial aspects of every microkernel. The message-passing interface (MPI) is a specification between different processes, which is used for communication amongst processes. Message Passing Interface Chameleon (MPICH) is the portable implementation of message passing interface. This paper delineates the comparison between IPC, MPI and MPICH in terms of...
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.
Hybrid Broadcast Broadband TV (HbbTV) became very popular during the last few years, because it provides the users with some new services when watching TV. This paper describes the new proposed application for the subtitle support in the hybrid digital TV applications with relatively simple hardware equipment. The subtitle files are downloaded from the server. Once the respective language is selected,...
This paper describes an implementation of a runtime environment for portable message-passing C programs with Message Passing Interface (MPI) library on web browsers. We have implemented core functions of the library. The runtime system runs several MPI programs without any modification. We confirm that the runtime performances of the programs are comparable to their native executions on some conditions.
Cyber-physical systems (CPS) are key enabling technologies for the fourth industrial revolution, referred to as Industrie 4.0 or Industry 4.0. The Reference Architecture Model Industrie 4.0 (RAMI4.0) has recently been standardized and OPC Unified Architecture (OPC UA) is listed as the sole recommendation for implementation of a communication layer. Many automation and control systems offer already...
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...
Pidgin communicator is a multiprotocol instant messenger client, developed by open source community. It was originally a third party client of AIM (AOL Instant Messenger) protocol for Linux operating system founded in 1998. At present, its main goal is to provide common interface for every protocol it supports, so the user does not need care about protocol to use or peer's IM identifier, while he...
We consider a system, containing a library of multiple files and a general memoryless communication network through which a server is connected to multiple users, each equipped with a local isolated cache of certain size that can be used to store part of the library. Each user will ask for one of the files in the library, which needs to be delivered by the server through the intermediate communication...
The recent development of stream delivery technology made Internet broadcasting services popular. In live Internet broadcasting, broadcasters or viewers often add video or sound effects (we call this kind of live broadcasting, ‘different worlds broadcasting’). Therefore, we have proposed a distributed Internet live broadcasting system with video and audio effects. In this paper, we describe the implementation...
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...
