Laboratory work, in the disciplines of engineering and physical sciences, has a strong impact on students' learning outcomes and it is considered to be at the heart of learning. Hardware experimental environment is usually treated as an exclusive resource for single user usage. However, the actual test run time is rather short and most of the time is wasted leaving these costly resources idle. With...
The use of meta-heuristics for designing efficient Grid schedulers is currently a common approach. One issue related to Grid based schedulers is their evaluation under different Grid configurations, such as dynamics of tasks and machines, task arrival, scheduling policies, etc. In this paper we present a web application that interfaces the final user with several meta-heuristics based Grid schedulers...
This paper proposed a new idea based on adaptation technologies for the Web Interface. Web usage mining is used as a mission for mining personalized information from users. We try to attack the problem from both function objects in the interface and the interface region. It is helpful to design algorithms for finding frequent function objects pairs and a subregional set, which is based on association...
All major experiments need tools that provide a way to keep a record of the events and activities, during both commissioning and operations. In ALICE (A Large Ion Collider Experiment) at CERN, this task is performed by the ALICE Electronic Logbook (eLogbook), a custom-made application developed and maintained by the Data-Acquisition team (DAQ), the group which within the collaboration has the responsibility...
There are several institutions that accredit educational programs and require documentation to ensure that an educational program regularly meets certain criteria. This paper focuses on ABET program. They require that programs show student achievement and certain course outcomes. Documentation of this requirement is particularly burdensome. There is no standard method of generating these reports,...
The institutional and thematic repositories seen as alternative models of scientific communication can provide significant contributions to accelerate the scientific processes. It's presented in this article an academic experiment with the implementation of a thematic repository used to store digital content from academic research undertaken in the laboratory. Using a system of repositories of content...
Nagios is a popular network monitoring tool that can be used to monitor network services as well as data like processor load due to an SNMP interface. The visualization of status and alert messages can be conducted with a Web interface. Many plugins for the Nagios system are available that extend its features, also wrt. visualization of data. But so far, none of them allows users of PDAs like, e.g...
In the near future, the wireless sensor networks (WSN) consisting of hundreds or thousands of small sensor devices are expected to become increasingly popular due to their low cost and easy use. As a distributed system, they are usually deployed in unattended environments and aim to collect useful information from the sensed area. In this paper, we present a Web interface model for habitat monitoring...
One of the main advantages of HPC clusters is the flexibility and efficiency they bring to their user. With the increasing number of applications being served by HPC systems, new systems need to serve multiple users and multiple applications. Traditional HPC systems typically served a single application at a given time, but to maintain maximum flexibility a new concept of ldquoHPC as a servicerdquo...
High-tech laboratories are an important kind of knowledge source, nevertheless most of today's laboratory architectures consist of tight coupled devices with proprietary interfaces. Although there are several approaches to implement cross-functional and heterogeneous infrastructures, these solutions do not consider high-tech laboratories. Therefore, we developed a service-oriented architecture for...
Electronic commerce is fast expanding all over the world. Currently most B2C (business to customer) electronic commerce focuses on retailing and other online services, such as online banking. Compared with large-scale enterprises and organizations, small businesses find it difficult to involve in electronic commerce because the cost is too high to be affordable. The cost for electronic commerce not...
BVCAM is a video recording service based on the H.323 protocol for videoconferencing on IP networks. BVCAM allows remote recording of H.323 sessions either as a point-to-point session or as an endpoint in a multipoint session. All recordings are controlled through a web interface. The initial conception of BVCAM was to complement synchronous communication in large group meetings so that distributed...
TexPlorer is an integrated system for exploring and analyzing large amounts of text documents. The data processing modules of TexPlorer consist of named entity extraction, entity relation extraction, hierarchical clustering, and text summarization tools. Using a timeline tool, tree-view, table-view, and concept maps, TexPlorer provides an analytical interface for exploring a set of text documents...
Although there are quite a few Open Source monitoring applications, they have not reached yet the necessary maturity level. Many users have to face important problems when deploying a monitoring system for their networks. In this paper we compare the most popular open source monitoring tools, and we analyze their main limitations. As a solution for these problems we propose a new monitoring tool,...
The resource description framework (RDF) is a language for representing information about resources on the web. However, RDF can also be used to describe other data and relationships between objects in the data. Many applications in the signal/image processing (SIP) community (such as radar imaging, electromagnetics, etc.) generate large amounts of data. Researchers would like to have online access...
Anomaly detection in the law enforcement domain is very important because it gives police agencies a method for discerning the difference between normal fluctuations and fundamental changes in a specific crime distribution. Currently, crime analysts must monitor the data manually to detect these anomalies because an automated tool does not exist. This paper describes the analysis, design, and implementation...
The opening of Packery Channel in the Texas Gulf of Mexico region presented an opportunity to adapt an existing coastal observing system for scientific discovery, while addressing regulatory issues and decision support. Maintained and operated by the Shoreline Environmental Research Facility (SERF), specifically the objectives were current monitoring with data acquisition systems having a real-time...
We proposed a distributed service oriented system with Web-based interface for medical information to promote the practical prediction of clinical prognosis. The proposed system provided hospitals secure access for medical information and processing simulations to examine effects of surgical treatments. Through a Web interface, users could operate the system in order to execute the simulations, access...
This paper presents an integrated database benchmark suite, which is named SIMS. SIMS offers generic benchmarks, custom benchmarks, and hybrid benchmarks to users on a unified Web interface. Users can run benchmarks in realistic environments by performing the workload generation facility of SIMS, which generates composite workloads similar to those of the real world. Using SIMS, users can easily implement...
The RIKEN Super Combined Cluster (RSCC) System in RIKEN Wako Inst., started its operation in March, 2004. A Web portal system called Bio Portal was developed to utilize a Linux cluster (a part of RSCC) for data analysis in the life sciences. A small SMP server was then placed in RIKEN Yokohama Inst., for small analysis, and the Bio Portal integrates both RSCC and this SMP server through the application...
