In the paper are analyzed articles that are indexed on Web of Science with the main topic of the conference “Communication and Information Technologies” (CIT). The articles were chosen the most cited ones. The first step of analysis summarizes statistics of the articles and the second step was oriented to detailed analysis using the software Tovek Tools. The contextual analysis was depicted in the...
Almost all college and university courses have integrated disciplines for the teaching of programming in their curricula. The importance of knowing “how to program” has contributed towards increasing private and public initiatives for the teaching of programming in different countries. Many of such initiatives include changes in the curriculum of primary and high schools, replacing disciplines by...
Buildings represent 40% of total primary energy use in the U.S., and researchers have recognized the necessity of making office spaces more energy efficient. To reduce energy consumption, it is important to take into account buildings occupants' behavior into account. The difference between simulated, estimated and real power consumption in buildings reflects the need to search for more accurate ways...
This paper introduces xDCI, a Data Science Cyber-infrastructure to support research in a number of scientific domains including genomics, environmental science, biomedical and health science, and social science. xDCI leverages open-source software packages such as the integrated Rule Oriented Data System and the CyVerse Discovery Environment to address significant challenges in data storage, sharing,...
In the open source community such as GitHub, developers usually need to find projects similar to their work, with the aim to reuse their functions and explore ideas of features that could be possibly added into their project at hand. Traditional text search engine can help detect similar resources. However, it is difficult for developers to use in open source community because a few query words cannot...
Since computing infrastructure has intrinsically a redundant logic, budget saving practices or understaffing of IT departments lead to an “emergency room” service paradigm. However, a treasure of information that could facilitate preemptive maintenance is buried in the logs and messages that are automatically generated by regular processes. Such information is typically ignored because of the shear...
Starting in 2010, one of the most important policies for the introduction of Digital Technologies in schools, in modalities 1 to 1, has been implemented in Argentina: The “Programa Conectar Igualdad” (PCI, for its acronym in Spanish). This program proposed two complementary goals: one related to digital inclusion, which far exceeds school's ambit, and another one related to the improvement of education...
The purpose of this pilot study was to describe web reference use patterns of poison control center specialists using time tracking software. We analyzed two weeks of web site use data from Utah poison control center (PCC) computers to describe patterns of reference web site use. We observed frequent use of webPOISONCONTROL and Amazon. Specialists visited additional reference web sites that feature...
Our society relies upon information processing at a scale never seen before in human history. We are indeed experiencing an exponential growth in processing demand, as more and more applications in the most disparate domains emerge. While continuous improvements in the manufacturing processes of microprocessors has been able so far to mitigate the ecological and economical costs this trend imposes,...
In this paper, we implemented OpenFlow scheduled bundle in the Open vSwitch software switch and evaluated its performance in SDN testbed networks under different scenarios. The scheduled bundle is a very new mechanism proposed in the OpenFlow protocol for achieving consistent updates among multiple SDN switches. However, this feature has not been supported in any hardware SDN switches or any software...
Software Defined Networking (SDN) and Network Function Virtualization (NFV) are catching the attention of telecom operators. Telecom environments establish a set of Carrier Grade requirements such as high availability, high throughput and low latency. To address these challenges SDN deploys logically-centralized controllers, such as ONOS and OpenDayLight. Based on the JAIN SLEE component model, which...
In this paper, we propose the China-US international data placement laboratory (iDPL) based on an inter-continental testbed for data placement research. iDPL is able to support various data placement research due to its scalability and flexibility in deploying the experiments in the real network environment. The core design of iDPL leverages reliable workflow management and lightweight I/O protocol...
Software-Defined Networks (SDN) rely on flow tables to forward packets from different flows with different policies. To speed up packet forwarding, the rules in the flow table should reside in the forwarding plane as much as possible to reduce the chances of consulting the SDN controller, which is a slow process. The rules are usually cached in the forwarding plane with a Ternary Content Addressable...
With the expanding load on healthcare and consequent strain on budget, the demand for tools to increase efficiency in treatments is rising. The use of prediction models throughout the treatment to identify risk factors might be a solution. In this paper we present a novel implementation of a prediction tool and the first use of a dynamic predictor in vocational rehabilitation practice. The tool is...
Over the last years, due to the emergency of new challenges in the area of the health care domain, particular emphasis was dedicated to the application of ICT in this sector. This, in turn, stimulated the analysis over the software requirements engineering techniques and their applicability in this context. The efficient application of the use-case based technique, within the PATHway project user...
We are currently witnessing an evolution towards network virtualization and Software Defined Networking (SDN) paradigm. SDN permits the decoupling of the control and data planes of traditional networks, and offers flexible and programmable networks. Besides, the need for dynamic provisioning and composition of networking services leads to the deployment of software components on virtualized network...
Virtual worlds and avatar-based interactive computer games are a hype among consumers and researchers for many years now. In recent years, such games on mobile devices also became increasingly important. However, most virtual worlds require the use of proprietary clients and authoring environments and lack portability, which limits their usefulness for targeting wider audiences like e.g. in consumer...
In this paper it is presented a new application of Levenshtein distance algorithm, for the selection of choices in a vocabulary quiz. Levenshtein distance is a measure for the similarity of two strings. In order to make the quiz more difficult, the choices for the correct word are selected using the calculated degree of similarity with the correct word. We developed a Java graphical application that...
The authors of this paper present the development of an automatic system used to convert computer written text to the Braille language. The system uses a microcontroller connected to a special device that can be read by blind persons. For this system, a software based concept to implementing Finite State Machines (FSM) has been developed. Experimental results are shown and discussed.
The life expectancy of digital excitation systems is influenced by the availability of spare and replacement parts. Many factors affect the ability of manufacturers to continue producing these systems and providing replacement parts. Strategies exist for prolonging the life of existing digital equipment and minimizing the cost impact of complete replacement.
