Case Study: Optimizing the Automated Acceptance Testing Infrastructure at SaleMove
Get PDFSaleMove on ettevõte, mis pakub tarkvara kui teenust. Kuna SaleMove asetab suurt rõhku oma tarkvara kvaliteedi tagamisele, on ettevõte huvitatud oma tarkvaraarenduse protsessi pidevast täiustamisest. Üks oluline osa selles tarkvaraarenduse protsessis on automatiseeritud vastuvõtutestide käitamine. Käesolev magistritöö optimeeribki selle tarkvaraarenduse protsessi olulise osaga seotud infrastruktuuri, eesmärgiga vähendada infrastruktuuriga seotud riistvaralisi kulutusi, vähendada viivitust vastuvõtutestide tagasiside saamisel ja suurendada infrastruktuuri paindlikkust kasvava arvu vastuvõtutestidega toime tulemise osas.Nende eesmärkide saavutamiseks analüüsitakse kõigepealt esialgse infrastruktuuri puudusi, mille järel pakutakse välja mitmeid täiendusi. Et vältida negatiivseid mõjusid ettevõtte igapäevatööle, katsetatakse neid täiendusi esialgu eksperimentaalsel koopial SaleMove’i tõelisest automatiseeritud vastuvõtutestimise infrastruktuurist. Peale esialgset mõjude hindamist, võetakse täiendused kasutusele ka SaleMove’i tõelises automatiseeritud vastuvõtutestimise infrastruktuuris ning tehakse tähelepanekuid nende täienduste mõju kohta praktilises kasutuses.SaleMove is a software-as-a-service company that places a high emphasis on the quality of its software and is therefore constantly looking to improve its software development process. An important part of that software development process is automated acceptance test execution. This thesis presents solutions that optimize the infrastructure related to that important part of the development process in order to reduce the associated hardware costs, reduce the delay in receiving acceptance testing feedback, and increase the infrastructure’s flexibility in dealing with a growing number of acceptance tests.To achieve these goals, the limitations of the initial infrastructure are analyzed, after which a number of enhancements are proposed. These enhancements are implemented and their impact is evaluated on an experimental duplicate of SaleMove’s automated acceptance testing infrastructure in order to avoid negatively interfering with the ongoing software development. Finally, the enhancements are also implemented on Salemove’s active automated acceptance testing infrastructure and observations are made about the effects of the enhancements in practical usage
A Study of Clustering Methods Using Visual Data
Get PDFKlasteranalüüs on laia kasutusvaldkonnaga andmeanalüüsi tehnika, mille rakendamiseks on olemas mitu erinevat algoritmi. Käesoleva töö eesmärk on anda ülevaade kolme levinuma klasteranalüüsi meetodi tööpõhimõtetest ja eripäradest, rakendades hierarhilise klasterda-mise, k-keskmiste klasterdamise ja Kohoneni võrgu algoritme näidisandmestiku peal. Li-saks algoritmide tööpõhimõtetele on kirjeldatud ka põhjus, miks näidisandmestikuks on valitud visuaalsed andmed ehk pildid ning kuidas on implementeeritud klasteranalüüsi meetodite rakendamiseks kasutatav skript. Töö sisaldab ka skripti rakendamisel saadud klasterduste analüüsi.Cluster analysis is a widely used data analysis technique that can be applied by using sev-eral different algorithms. This thesis aims to give an overview of the working principles and specifics of the three most commonly used cluster analysis methods by applying hier-archical clustering, k-means clustering and self-organizing map algorithms on sample data. In addition to the description of working principles of the clustering algorithms, there is also a description of how the script used for applying the clustering methods is implement-ed and an explanation for why visual data or pictures are chosen as the sample data. The thesis also includes an analysis of the clustering results produced by the script
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
