Abstract. Despite the availability of both commercial and open-source software, an ideal tool for digital rock physics analysis for accurate automatic image analysis at ambient computational performance is difficult to pinpoint. More often, image segmentation is driven manually, where the performance remains limited to two phases. Discrepancies due to artefacts cause inaccuracies in image analysis. To overcome these problems, we have developed CobWeb 1.0, which is automated and explicitly tailored for accurate greyscale (multiphase) image segmentation using unsupervised and supervised machine learning techniques. In this study, we demonstrate image segmentation using unsupervised machine le…

Automatic detection of cervical cells in Pap-smear images using polar transform and k-means segmentation

2016

We introduce a novel method of cell detection and segmentation based on a polar transformation. The method assumes that the seed point of each candidate is placed inside the nucleus. The polar representation, built around the seed, is segmented using k-means clustering into one candidate-nucleus cluster, one candidate-cytoplasm cluster and up to three miscellaneous clusters, representing background or surrounding objects that are not part of the candidate cell. For assessing the natural number of clusters, the silhouette method is used. In the segmented polar representation, a number of parameters can be conveniently observed and evaluated as fuzzy memberships to the non-cell class, out of …

Ergonyms of Educational and Cultural spheres in two of Baltic States cities

2020

Daugavpils (Latvia) and Narva (Estonia) are cities in the Baltic States and signifi cant cultural and economic centres of their respective countries. These cities are characterized by a minority of nationals (19.8% of residents of Daugavpils are Latvian, 4% of residents of Narva are Estonian) and a similar linguistic situation: there is a dominance of Russian in the press, television and radio, but the state language prevails in the urban language signs.The aim of the study is to analyse the linguistic and extralinguistic means used for the creation of ergonyms of educational and cultural spheres. The main criteria for the analysis are: language choice, grammatical structures, sources of pr…

Beyond Tandem Analysis: Joint Dimension Reduction and Clustering in R

2019

We present the R package clustrd which implements a class of methods that combine dimension reduction and clustering of continuous or categorical data. In particular, for continuous data, the package contains implementations of factorial K-means and reduced K-means; both methods combine principal component analysis with K-means clustering. For categorical data, the package provides MCA K-means, i-FCB and cluster correspondence analysis, which combine multiple correspondence analysis with K-means. Two examples on real data sets are provided to illustrate the usage of the main functions.

Los beneficios del mar: negocios e inversiones económicas de la oficialidad naval en el siglo XVIII

2019

Throughout the eighteenth century, the Spanish navy was extensively reformed and enhanced as a consequence of the new model of Monarchy that the Bourbons introduced. Among the measures adopted, it is remarkable the erection of the naval officers corps according to the needs and obligations that maritime war had in this century. This group becomes the paradigm of the new professionalization and new training approach, and its members had great relevance due to its great mobility around the empire and the power of the naval institution. This means that a part of the naval officers were placed in privileged positions and at the intersection of diverse political, social and economic networks. Th…

Wykorzystanie środków unijnych w obszarze edukacji w województwie opolskim w latach 2004 - 2015. Wybrane problemy

2017

Korzystanie przez Polskę ze środków unijnych bywa kontestowane. Wydaje się konieczna i rzetelna ocena w różnych obszarach naszego życia społecznego, zwłaszcza w edukacji, zakresu i sposobu ich wykorzystania. Środki unijne w dużym stopniu wsparły różne działania. Jednak od nas samych zależy na co je wykorzystamy i jak je spożytkujemy. Badania przeprowadzone na terenie województwa opolskiego i gmin z województw sąsiednich pozwalają na stwierdzenie, że środki te przyczyniły się do aktywizacji nauczycieli, dyrekcji szkół, gmin, placówek edukacyjnych w pozyskiwaniu środków na działania podnoszące poziom wiedzy i umiejętności uczniów. Z przeprowadzonych badań wynika, że środki pozyskane za sprawą…

Pārliecināšanas līdzekļu analīze modes žurnālos

2022

Lai gan netrūkst pētījumu par jautājumiem, kas saistīti ar ātro modi, ilgtspējīgu patēriņu, plašsaziņas līdzekļiem un pārliecinošo diskursu, ir salīdzinoši nedaudz pētījumu, kuros pievērsta uzmanība ātrās modes pārliecinošajai valodai, salīdzinot to ar ilgtspējīgu patēriņu.Tādēļ bakalaura darba mērķis ir noteikt pārliecināšanas līdzekļus, kas tiek lietoti, diskutējot par ātrās modes un ilgtspējības tēmām. Pētījums ir veikts, izmantojot satura analīzi. Pētījuma rezultāti parādīja, ka modes žurnālos tiek izmantoti tādi pārliecināšanas līdzekļi kā "personisko vietniekvārdu", "grupas" un "vairākuma" stratēģijas, kas saistās ar neitrālām un pozitīvām emocionālām konotācijām. Viens no papildu sec…

Stilistiskie izteiksmes līdzekļi pārtikas produktu reklāmas plakātos

2021

Bakalaura darba tiek pētīti stilistiski līdzekļi ar pārtiku saistītās drukas reklāmās. Reklāma ir īpaši nozīmīga un izplatīta mūsdienu sabiedrībā, tāpat kā nepieciešamība pēc zinātniskiem pētījumiem un izpratne par tās ietekmes sfērām, kas lielā mērā nosaka reklāmas tekstu lingvistiskās un stilistiskās iezīmes. Darbā tiek pētīti stilistiski pārtikas produktu reklāmas līdzekļi, ko izmanto vadošie starptautiskie pārtikas mazumtirgotāji, kas darbojas Latvijas tirgū. Pētījuma rezultāti tika apkopoti un analizēti, izmantojot nejaušas izlases metodi materiāla atlasei un strukturālās analīzes metodi, kas ļāva šī darba autoram veikt secinājumus, kas pierādīja, ka stilistiskie līdzekļi tiek plaši iz…
