Developing of mobile applications on the google android phone 2
No full textSocial networking sites have been a growing trend around the world and they change the way how people communicate today. With the rapid advancement in technology, integrated program such as Global Positioning System (GPS) is widely used in the mobile phones.
However, given the current existing sites, there is no platform where a user can search for other users and friends that are around him/her using his/her current location.
The purpose of this project is to develop a mobile application that combine the idea of social and location-based networking site. This application will allow users to have a new social experience through social networking based on their current location, to make new friends and meet up with friends who are nearby.
The application is successfully implemented on the Android platform, using MySQL database. Users can communicate with other registered users given their current location.
A user acceptance survey is conducted and the results show that 90% of the surveyors expressed their interest in using the application if it is available in the market.
Based on the survey results, the users wish to see more features in the application such as flipping of photos while viewing the album. Thus, future works of extra features will be included.Bachelor of Engineering (Computer Engineering
Group key management for wireless networks
No full textWith the advancement of wireless networks in recent years, group communication via wireless networks is becoming an increasingly popular research area due to the growth of group oriented applications such as video conferencing, pay-per-view media distribution, real-time information services and collaborative work in wireless networks. Besides civilian applications mentioned above, group-oriented applications and protocols are also used widely in military operations. However, group communication via wireless networks takes place over radio waves, the common mode of communication in wireless networks, causes major security concern as radio transmission can be easily eavesdropped. Solutions such
as IPSec that provides end-to-end secure communications between two communicating parties and user nodes would require many different secret keys to communicate with every other node in the network. A better solution is to use a shared secret group key for secure group communications in a wireless network. To achieve this, the nodes in the wireless network will first run a group key management (GKM) protocol to establish a common group key. This key will then be used as a secret key for symmetric-key cryptography to encrypt messages that they wish to broadcast to the wireless network. In this way, entities outside the wireless network will not be able to decode these messages.DOCTOR OF PHILOSOPHY (EEE
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
