We present a resilient task-based domain-decomposition preconditioner for partial differential equations (PDEs) built on top of User Level Fault Mitigation Message Passing Interface (ULFM-MPI). The algorithm reformulates the PDE as a sampling problem, followed by a robust regression-based solution update that is resilient to silent data corruptions (SDCs). We adopt a server-client model where all...
In modern day and age, multicore processors along with parallel programming plays a significant role in enhancing the performance of the applications. The performance of processor solely depends upon how efficient the parallel programming has been implemented in the system. In this paper parallel programming application is developed for those environments which rely on multi-user, multi-tasking and...
We present a domain-decomposition-based pre-conditioner for the solution of partial differential equations (PDEs) that is resilient to both soft and hard faults. The algorithm is based on the following steps: first, the computational domain is split into overlapping subdomains, second, the target PDE is solved on each subdomain for sampled values of the local current boundary conditions, third, the...
With increasing numbers of devices per user, data delivery and annoyance problems arise from sending real-time or near real-time application push notification messages to all these devices. This paper presents a push notification service approach that is based on a user-centric viewpoint to deliver notification messages to the right device at the right time. The approach increases the chances of a...
This paper reports on an algorithm for planning a practical trajectory for a surface vehicle that provides range measurements to an autonomous underwater vehicle (AUV). We consider server-client cooperative localization in which a server vehicle provides relative range constraints to minimize the uncertainty of a client vehicle. Our approach assumes the nominal client mission plan is available and...
Many IaaS providers allow cloud consumers to define elasticity (or auto-scaling) rules that carry out provisioning or de-provisioning actions in response to monitored variables crossing user-defined thresholds. Defining elasticity rules, however, remains as a key challenge for cloud consumers as it requires choosing appropriate threshold values to satisfy performance and cost requirements. In this...
CosyVerif aims at gathering within a common framework various existing tools for specification and verification. It has been designed in order to 1) support different formalisms with the ability to easily create new ones, 2) provide a graphical user interface for every formalism, 3) include verification tools called via the graphical interface or via an API as a Web service, and 4) offer the possibility...
This paper presents distributed real-time robot control system implemented on the client and server modules. The client module is used to control the real robot and send commands to the server module. An application on the server side receives the commands that contain positions of robot joints read from encoders, displays current robot coordinates and 3D robot motions through virtual model of a real...
With the rapid development of wireless network, online reading has become available in mobile reading devices. E-reader users can read and buy books through wireless network. Users can not only access to real-time comprehensive resource, but also access to book reviews, book recommendations etc. 3G communicating technology significantly improved data transfer speed which can meet network transmission...
Web users and content are increasingly being geo-positioned. This development gives prominence to spatial keyword queries, which involve both the locations and textual descriptions of content. We study the efficient processing of continuously moving top-k spatial keyword (MkSK) queries over spatial keyword data. State-of-the-art solutions for moving queries employ safe zones that guarantee the validity...
This paper describes the work-in-progress carried out at the Carinthia University of Applied Sciences to create a LabVIEW based toolkit that aims at providing laboratory developers with a tool to easily develop new batched lab servers for the iLab Shared Architecture.
We propose a novel collaborative caching framework to support spatial query processing in Mobile Peer-to-Peer Networks (MP2PNs). To maximize cache sharing among clients, each client caches not only data objects but also parts of the index structure built on the spatial objects. Thus, we call the proposed method structure-embedded collaborative caching (SECC). By introducing a novel index structure...
Currently the most popular secure protocol is SSL (Secure Sockets Layer), but it has some negative aspects: First, it imposes a heavier burden on handheld wireless devices, and when a certificate uses PKI (Public Key Infrastructure) e.g. RSA algorithms, it takes a long time to establish a secure connection between client and server. This paper proposes a lightweight protocol based on the SSL protocol,...
In today's IT computing era, there is shift to aggregate computing resources into data centers (DC) shared by pool of users. With the increasing popularity of cloud computing, this pool of users are now more global than any-time in the past The resource demand of these users are inadvertently governed by strict “service level agreements”. In this paradigm, data centers' operational energy costs are...
Aiming at the problems of that capital information, project information and enterprise information scattered, and the lack of supporting for the trading platform in Shanxi venture capital management, this paper summarizes the venture system and platform construction contents of Shanxi province. And based on the study on BS rich client technology, the paper brings out a venture capital information...
One to one download model cost much time when target machine number is very large in embedded system. This paper introduce client/server download model to solve above problem, it can cost less time than one to one model. Borrow ideas from linux convention upgrade model. Server sends initiative upgrade instruction, client is target machine in this paper receive passively, that is good for server management...
Recent mobile device and vision technology advances have enabled mobile Augmented Reality (AR) to be serviced in real-time using natural features. However, in viewing augmented reality while moving about, the user is always encountering new and diverse target objects in different locations. Whether the AR system is scalable or not to the number of target objects is an important issue for future mobile...
The paper introduces the design and the realization of the gating management system of reading room. It is a multi-user and multi-task system which based on Windows98/NT. It contains client and server. One Client is made up of a Reading-Card part and a PC, which communicate through Rs232 port. SQL Server2000 is used as the background database server.
Data availability in mobile information systems is lower than in traditional information systems due to its limitations of wireless communication such as low bandwidth, instability, and easy disconnection. Cooperative data caching is an attractive approach to this problem. This paper proposes an efficient approach for cooperative caching in mobile information systems. We use references to share data...
The credit rating system for bank customers is based on J2EE technology architecture, is designed from the data sources, customers rating, approval rating and safety management and other aspects. In the paper, we describes the construction of bank customers in the background of credit rating system which is discussed in detail the application of Client/Web server/Application server/Database server...
