Smart Doorknob Cleanser
No full textDuring the sensitive times of a global pandemic, we have learned over time that diseases such as Covid-19 can live on surfaces for days. The senior project idea is to design, construct, and implement a prototype able to disinfect doorknobs after the surface has been encountered or used. To fight against harmful bacteria's, there is a need to attack one of the main sources where bacteria is being transmitted the most. In fact, scientists have determined that on average a minimum of at least five different colonies of bacteria are on a single doorknob at any given time. The purpose of the device is to spray a mist of alcoholic solution onto the doorknob surface allowing the solution to disinfect the main surface area. The main objective of this project is to keep the environment clean and reduce the spread of viruses and germs. In addition, the device is set to follow constraints that provide the opportunity for the device to be cost effective, efficient, and adjustable. As a result, these constraints will improve productivity, safety, and be more user friendly to consumers. By applying previous engineering coursework, the plan is to incorporate notes from classes such as fluid mechanics, machine design, network analysis, and computer aided design to fulfill the needs of the project. The device is planned to include a fluid mechanism that will be used to spray the alcoholic solution after the doorknob has sensed motion within a specific time interval. Also, referring to the constraints of the project implementing a refillable cartridge with automated fill level notification would be ideal in making sure the alcohol solution can be easily replaced when the cartridge has reached a level of emptiness. These fill levels will be indicated in a form of a display screen communicating to the consumer that the cartridge is empty, half empty, or full and ready for use. This ensures the device is indeed performing and communicating whether the solution needs to be refilled. Overall, the goal is to create a sanitized and trusted environment for consumers when utilizing the smart doorknob sensor. This device would be used as a combat against diseases being transmitted in public areas such as office buildings, schools, and public bathrooms
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
Portable Car-Washing System
No full textThe Portable Car-Washing system was developed for the benefits of improving consumer focus. The system was designed to provide comfort, convenience, improve health, and durability to consumer vehicles. Many consumers face scenarios where their vehicles are being damaged by car washing companies. In fact, car wash companies are known to tear off antennas, side view mirrors, and front/ rear bumpers. Also, harsh chemicals and low-quality car shampoo are being used at these establishments which eventually cause rust. These harsh chemicals can vary from all brands of industrial strength alkaline enhanced degreasing shampoo which leads to oxidation of the paint and corrosion. On the other hand, devices such as the Portable Car- Washing system are innovating a touchless car wash facility introducing a safer washing system
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
