On the conceptual design of waverider forebody geometries
Get PDFThis paper summarizes the results of investigations into the parametric geometry modeling of waverider forebodies, mostly centered on the osculating cones design method. Initially, three different approaches to controlling the leading edge shape are discussed. The first and most common method is driven by prescribing the upper surface trace on the base plane. The second incorporates a planform definition of the leading edge shape that gives more direct control of the sweep angle of the forebody. The third method directly controls the lower surface’s trace on the base plane. The shockwave profile curve that defines the shape of the shock is defined by its trace on the base plane for all three cases. Each method provides direct control over different aspects of the geometry for which a desired shape would be more complex to obtain indirectly. We then estimate the level of flexibility required by the design-driving curves in the context of a design optimization study, in order to enable a variety of meaningful designs without needlessly complicating the geometry model. Additionally, we show an efficient and robust method to introduce bluntness to the leading edge of waverider forebodies utilizing rational Bézier curves

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
Information service 1188 database evolution and implementation of new features
No full textŠajā darbā tiek apskatītas 1188 uzziņu dienesta sistēmas un to pakalpojumu raksturojums, detalizēti apskatot piedāvāto Interneta uzņēmumu katalogu un parādot tā iespējas. Aprakstīta uzņēmumu kataloga datu bāzes struktūra, kas, savukārt, satur informāciju par visiem Latvijā reģistrētiem uzņēmumiem un organizācijām, kā arī ģeogrāfiskajiem objektiem.
Ir apskatītas galvenās datu bāzes tabulas un datu bāzes automātiskās atjaunošanas procedūra, tās priekšrocības un trūkumi. Galvenā uzmanība tika pievērsta datu bāzes izmaiņu uzdevumiem un tās nepieciešamībai.
Tika veikta 1188 uzņēmumu kataloga datu bāzes pārveidošana, kas iekļauj izmaiņas datu bāzē un datu struktūrā un sastāv no diviem etapiem: datu atjaunošanas optimizācijas un jauno iespēju realizācijas. Pārveidošanas mērķis ir padarīt datu bāzes atjaunošanu ērtāku un ātrāku, papildināt katalogu Internetā ar iespējām apskatīt uzņēmumu atrašanās vietas un attēlot Rīgas pilsētas un piepilsētas maršrutus interaktīvajā kartē.
Ir dots uzlabota 1188 uzņēmumu kataloga Internetā salīdzinājums ar citiem līdzīgiem ārvalstu katalogiem.The work deals with the 1188 system and the services it provides. A detailed discuption is given of the directory of 1188 yellow pages on the Internet and the opportunities. The structure of the catalogue’s database, which contains information of the enterprises and organizations registered in Latvia and geographical objects, is described.
The principal tables of the database, automatic database updating and its advantages and drawbacks are considered. The present work pays a great attention to purposes of database changes.
Transformation of the 1188 yellow pages’s database has been accomplished. It includes database and date structure changes and consisted of two stages: optimisation of data updating and implementation of new features. The purposes of transformation were to make 1188 database updating faster and handy and to add the functions of positioning the enterprises and Riga city transport routes on the map.
A comparison of 1188 yellow pages with foreign analogoes catalogues is provided
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
