Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
Characteristics and trends of orthopedic publications between 2000 and 2009
No full textBackground: This study was undertaken to investigate the trends of orthopedic publications during the last decade, and to document the country of origin, journal, funding source, and language of contribution using PubMed. Methods: Orthopedic articles published between 2000 and 2009 were retrieved from PubMed using the following search terms: orthopaedic[Affiliation] AND (2000/1/1[PDAT]: 2009/12/31[PDAT]) and orthopedic[Affiliation] AND (2000/1/1[PDAT]: 2009/12/31[PDAT]). The articles were downloaded in XML file format, which contained the following information: article title, author names, journal names, publication dates, article types, languages, authors' affiliations and funding sources. These information was extracted, sorted, and rearranged using the database's management software. We investigated the annual number of published orthopedic articles worldwide and the annual rate of increase. Furthermore, the country of publication origin, journal, funding source, and language of contribution were also investigated. Results: A total of 46,322 orthopedic articles were published and registered in PubMed in the last 10 years. The worldwide number of published orthopedic articles increased from 2,889 in 2000 to 6,909 in 2009, showing an annual increase of 384.6 articles, or an annualized compound rate of 10.2%. The United States ranked highest in the number of published orthopedic articles, followed by Japan, the United Kingdom, Germany, and the Republic of Korea. Among the orthopedic articles published worldwide during the last 10 years, 37.9% pertained studies performed in the United States. Fifty-seven point three percent (57.3%) of articles were published in journals established in the United States. Among the published orthopaedic articles, 4,747 articles (10.2%) disclosed financial support by research funds, of which 4,688 (98.8%) articles utilized research funds from the United States. Most articles were published in English (97.2%, 45,030 articles). Conclusions: The number of published orthopedic articles has been increasing over the last decade. The number of orthopedic articles, journals publication, and funding sources were dominated by research conducted in the United States, while share and growth of Asian countries including Japan, the Republic of Korea, and China were notable. © 2011 by The Korean Orthopaedic Association.Y
Energy-Aware Discrete Probabilistic Localization of Wireless Sensor Networks
No full textLocalizing sensor nodes is critical in the context of wireless sensor network applications. It has been shown that, for some applications, low-overhead discrete localization achieves results comparable to costly fine localization. This research presents a hybrid energy-aware discrete localization method that requires no transmission overhead from the sensor nodes. The proposed method, E-KalmaNN, is a combination of a Kalman-inspired localization and Artificial Neural Networks estimation that updates the position of a node with respect to a mobile reference. E-KalmaNN runs on the sensor nodes and supports different listening-wakeup frequencies for different nodes to balance power requirements with localization accuracy for each node. Simulation results show that the method converges to the correct position of the node in a relatively short time with high average location accuracy. Compared to the localization methods found in the literature, E-KalmaNN localizes with comparable accuracy, lower transmission costs and-or fewer motion restrictions. © 2013 Copyright TSI® Press.Amro A., 2008, IEEE ASME INT C ADV; Bulusu N, 2000, IEEE PERS COMMUN, V7, P28, DOI 10.1109-98.878533; Elhajj I.H., 2006, IEEE RSJ INT C INT R; Galstyan A., 2004, P 3 INT S INF PROC S, P61, DOI 10.1145-984622.984632; Gorski J., 2005, IEEE ASME INT C ADV, P735; Hu L., 2004, P 10 ANN INT C MOB C; Karl H, 2005, PROTOCOLS AND ARCHITECTURES FOR WIRELESS SENSOR NETWORKS, P1, DOI 10.1002-0470095121; Kecman V., 2001, LEARNING SOFT COMPUT; Khan Haseebulla M., 2006, P 2 IEEE WORKSH DEP; Moore D., 2004, P 2 ACM C EMB NETW S; Priyantha N.

Towards a methodology for large-sample prompt-gamma neutron-activation analysis
No full textLarge-sample prompt-gamma neutron-activation analysis, or shortly LS PGNAA, is a method by which mass fractions of elements can be determined in large samples with a mass over 1 kg. In this method the large sample is irradiated with neutrons. Directly (prompt) after absorption of the neutrons photons are emitted. The presence of elements can be derived from the energy of the photons. In small samples the mass fractions of elements can be calculated directly from the measured intensities of the photons. However, when large samples are analysed there has to be corrected for three effects. These are (i) the absorption of neutrons, (ii) the scattering of neutrons and (iii) the absorption of photons. For each position in the sample the specified effects are studied separately with Monte Carlo simulations. Finally the correction methods are combined in a method for LS PGNAA. This method was tested by the determination of the mass fraction of silicon in four different samples. The mass fractions could be determined within 10 % error of the real value.Interfaculty Reactor Institut
Discrete probabilistic localization of wireless sensor networks
No full textLocalizing sensor nodes is critical in the context of wireless sensor networks applications. It has been shown that, for certain applications, low overhead discrete localization achieves comparable results to costly fine localization. This paper presents a discrete and probabilistic localization method that requires no transmission overhead from the sensor nodes. The method is based on Kalman estimation that iteratively predicts and updates the position of a node with respect to a mobile reference. Simulations show that the method converges to the true position in a relatively short time with an average location accuracy of 91.1percent. © 2008 IEEE.Elhajj I.H., 2006, IEEE RSJ INT C INT R; Galstyan A., 2004, P 3 INT S INF PROC S, P61, DOI 10.1145-984622.984632; Gorski J., 2005, IEEE ASME INT C ADV, P735; Hu L., 2004, P 10 ANN INT C MOB C; Moore D., 2004, P 2 ACM C EMB NETW S; Priyantha N.

Multi agent-based control architecture in intelligent transportation system with infrastructure-based sensing
No full textTraffic congestion has negative impact in our life. In 2001, the European Commission estimated costs of congestion at around 120 billion Euro. The research of Intelligent Transportation System (ITS) becomes interesting since infrastructure expansion in not always feasible. In order to find out the impact of automated vehicle and intelligent infrastructure to traffic performance, we develop a model of hierarchical vehicle controller and intelligent infrastructure and implement them in a simulated environment using Multi Agent System concept. Several traffic scenarios are deployed to observe the effect of the designed vehicle controller and the model of intelligent infrastructure in traffic.MediamaticsElectrical Engineering, Mathematics and Computer Scienc
The impact of digital transformation
No full textDigital Transformation, Digital Technologies, Social, Mobile, Analytics, Cloud, Organizational Effects, Business Models, Business Model Canvas, Data-analysis, Survey. Many organizations nowadays feel pressured to change in order to meet customer demands and competitive pressure due to emerging digital technologies. When a combination of digital technologies is used a common heard buzzword is digital transformation. To date there only little academic research with regards to digital transformation and they often provide holistic non-deterministic definitions. In addition literature that dives deeper into the underlying technologies and effects only address specific elements or industries. This gap is address through a literature research and a business model based questionnaire held amongst IT consultants to determine both the concept and expected effects of digital transformation. We speak of digital transformation if a technology induced change by social, mobile, analytics or cloud technologies significantly impacts a minimal of three out of seven dimension on an individual, firm or social level. The research findings show that digital transformation is expected to change organizations across many different fronts as almost all business model constructs have at least one element that is expected to change moderately or even stronger. The greatest impact will be to organizations’ their value proposition, the customer segments they can identify and serve, the way organizations reach their customers, and the resources they use.Technology, Policy and ManagementSystem Engineering, Policy analysis and Managemen
