    Drone or unmanned aerial vehicles (UAV) technology nowadays constantly evolving from day to day. This technology has widely used in many sectors such as agriculture, public services, aerial surveillance, media, delivery and others. In modern robotic industry, drone can be the best approach to replace robotic arm especially in MIG welding industry. Using drone technology, it can reduce the problem in term of limit length for welding as it doesn’t need a platform such as railways to move and perform the welding process. This can reduce the cost in building the railways and labour cost. Thus, the feasibility of combining technologies (drone and welding) in robotic welding industry and the integration of welding gun operate autonomously using relay are studied. In this research, the type of the drone use is hexa which is six propellers and this drone will fly autonomously from one point to another point using path generated in Mission Planner software. During the flight, the drone will carry the welding gun which was installed on it to perform welding process. A relay is used to trigger the welding gun to operate or not during the flight through Mission Planner. The result obtained shows that the drone cannot perform welding 1m above the ground because of the circulation of wind under the drone. Moreover, the drone cannot move to each points precisely and this affect the welding path as the resolution of GPS is big. For future work, the drone is suggested to use technology such as optitrack for non-GPS navigation as this help the drone to move from one point to another point precisely

    Coffee table is a small low table usually placed in front of a sofa for holding bowls, magazines and others. Nowadays, people were use new raw material to create, coffee table such as epoxy resin which has some excellent characteristic that can be used in furniture production. In this study, the epoxy coffee table with wood disc decoration was designed and produced by using combination of wood disc from tree branches, epoxy resin and metal as the main raw material. The use of wood disc in this product was to reduce the waste from logging activities. After the product has been produced, the survey was done by distributing a set of online questionnaire through Google form application that involves 150 respondents including lectures, staff and students from Faculty of Applied Science UiTM Pahang campus Jengka. The issues have been analysed such as knowledge, raw material, design, marketing and satisfaction. Based on the result, most of the correspondents agreed about suitability of raw material, design of product, suitable price and the product can be commercialized in the market. Based on demographic analysis, there was indicated gender, profession, income and age. For the descriptive analysis results shows that the mean 4.34 for marketing variable was highest value for the rating score. Next, comparative analysis results show the gender indicated that male respondents get higher mean rating for marketing compared to female. For the profession, staff gave higher mean rating to all factors, the respondents who have income RM 1,000 to RM 3,000 give higher mean rate compared to others and lastly for age, from 50 years old and above give highest value mostly for all factors. Generally, based on correlation analysis shows the positive moderate correlation value for all factors included against customer satisfaction

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 PDF
    We 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 PDF
    We 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

    We 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
