Doç. Dr. Nur Zincir HEYWOOD Nisan 2000, 107 sayfa Bu tezde akademik, ticari ve askeri kuruluşların tümünde gittikçe daha hızlı büyüyen yerel ve geniş alan bilgisayar ağlarının yönetimi konusu incelenerek, ağ yönetiminin dinamik ve statik bileşenleri araştırılmıştır. Ağ yönetimi görevlerinin Konfigürasyon, Hata, Güvenlik, Muhasebe ve Performans gibi beş temel fonksiyonel bileşeni incelenmiştir. Bu incelemelerden sonra, bilgisayar ağı yönetimi konusunda, ağ yöneticileri tarafından örnek olarak kullanılabilecek bir yönetim modeli ana hatlarıyla açıklanmıştır. Ağ yönetimi ile ilgili genel hususlardan sonra, günümüzde kullanılan "SNMP", "CMIP" ve "RMON" gibi yönetim protokolları sırayla araştırılmıştır. Günümüzde endüstride kullanılan ağ yönetim ürünlerinin nasıl olması gerektiği konusunda bilgiler verilmiş ve kullanılan araçlardan bazıları tanıtılmıştır.

Sc. in Computer Engineering Supervisor: Yrd. Doç. Dr. Nur Zincir HEYWOOD April 2000, 107 pages The aim of this thesis is to research the dynamic and static constituents of network management by studying the management of local and wide area networks which gain an increasing importance in all academic, industrial and military organizations. The five basic functional areas of network management tasks such as configuration, fault, security, accounting and performance have been examined. Following the aforementioned studies, a management model which could be used as a sample by the network managers has been outlined. Following the common principles of network management, management protocols currently used such as "SNMP", "CMIP" and "RMON" have been researched respectively in terms of their pros and cons. Thereafter, Information has been provided on how the network management tools should be, together with a few examples of such tools currently used. Keywords: "Network managemenf, "SNMP", "CMIP", "RMON", "Configuration managemenf, "Fault management", "Security managemenf, "Accounting managemenf, "Performance managemenf
Host Based Dynamic Throughput Maximization Model for Ieee 802.11 Wlan
No full textErcan, Tuncay/0000-0003-0014-5106; Koyuncu, Murat/0000-0003-1958-5945As the demand for uninterrupted Internet access grows, the popularity of wireless communication increases. However, wireless communication has some problems compared to conventional wired communication. Especially, if widely used Wireless Local Area Network (WLAN) applications are taken into consideration, it becomes an important issue to balance the load among available access points. It is impossible to balance the load when wireless hosts associate with an access point by using the classical approach of Received Signal Strength Index (RSSI). Some solutions containing a central server, requiring a specific brand of access point or protocol revisions have been proposed previously, but none of them has been favored as a generally accepted solution. In this study, a proposal which is central server free and requires no modifications to the existing infrastructure is presented. The proposed model is based on a dynamic determination of the least loaded access point to associate with, in order to balance load and maximize throughput.Conference Proceedings Citation Index - Scienc
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
