A FRAMEWORK FOR THE MEASUREMENT AND PREDICTION OF AN INDIVIDUAL SCIENTIST’S PERFORMANCE

Author(s): Endel Põder / Language(s): English / Issue: 1/2017

Quantitative bibliometric indicators are widely used to evaluate the performance of scientists. However, traditional indicators do not much rely on the analysis of the processes intended to measure and the practical goals of the measurement. In this study, I propose a simple framework to measure and predict an individual researcher’s scientific performance that attempts to take into account the main regularities of publication and citation processes and the requirements of practical tasks. Statistical properties of the new indicator – a scientist’s personal impact rate – are illustrated by its application to a sample of Estonian researchers.

A heuristic algorithm based on hydrophobic amino acids sequences in HP protein folding problem

Author(s): Metodi Traykov,Slav Angelov / Language(s): English / Issue: 1/2020

The protein structure prediction is of massive significance because the properties of the proteins are critically determined by their structures. The protein structure prediction problem (Protein Folding Problem) is to predict the compact three-dimensional structure of a protein based on its amino acid sequence. Therefore, the protein folding problem is a computationally challenging problem. In this article, we will study the behavior of heuristic algorithm for protein folding problem, above sequences of hydrophobic amino acids only. The article is for educational purposes.

A LOW TE(A)CH APPROACH TO DIGITAL HUMANITIES

Author(s): Liviu Pop / Language(s): English / Issue: 1/2017

Technological fatigue is spreading due to the increased arrays of technological branches and the rapid pace of development. Keeping up with the latest and newest might prove not only difficult and tiring, but also not necessarily recommended to beginners in digital humanities. A more “back to the basis” approach might be more useful for students that don’t have technical backgrounds.

A Method for Modeling a Schema for Graph Databases

Author(s): Peretz Shoval / Language(s): English / Issue: VIII/2018

The recent decade had brought about massive growth in the Web and Web data - pictures, documents, videos and more. What worked well for years with relational databases is not well suited for the unstructured massive amounts of data and applications that are part of the Web, such as social networks. As a result, new types of database have emerged, including NoSQL (“not only SQL”) databases. Graph data-bases are one type of NoSQL database.

A METHODOLOGICAL MODEL OF AN ELECTRONIC COLLECTION OF WIDESPREAD EUROPEAN FOOD IDIOMS

Author(s): Petronela Savin / Language(s): English / Issue: 31/2014

The present paper aims at presenting the research methodology for creating an electronic collection of widespread European food idioms, corresponding to the shared European cultural heritage. This study intends to make use of digital scientific lexicographical methods in the field of phraseology, providing an answer to the challenge regarding the research strategies of studying language from the perspective of cultural universals. Even if the cross-linguistic similarities of idioms according to their cultural foundations seem to gain ground in today's research, the electronic collections are less convincing. In response to the current situation of the onomasiological cross-linguistic corpus of idioms, our study’s main objective is the elaboration of a methodological model of an electronic collection of widespread European food, which exceeds the perspective of a simple compilation of phrasemes that are separately treated and alphabetically ordered, but organised as organic elements related to a coherent system.

A Monte Carlo Method for Image Classification Using SVM

Author(s): Emanouil Atanassov,Aneta Karaivanova,Sofiya Ivanovska,Mariya Durchova / Language(s): English / Issue: XI/2021

Support Vector Machines are a widely used tool in Machine Learning. They have some important advantages with regards to the more popular Deep Neural Networks. For the problem of image classification, multiple SVMs may be used and the issue of finding the best hyperparameters adds additional complexity and increases the overall computational time required. Our goal is to develop and study Monte Carlo algorithms that allow faster discovery of good hyperparameters and training of the SVMs, without impacting negatively the final accuracy of the models. We also employ GPUs and parallel computing in order to achieve good utilisation of the capabilities of the available hardware. In this paper we describe our methods, provide implementation details and show numerical results, achieved on the publicly available Architectural Heritage Elements image Dataset.

A Practical Approach to Ascertaining the Accuracy and Resolution of Post Rendered 3D Models Acquired Originally via 3D Digitization

Author(s): Feng Zhao,Soo Choon Loy / Language(s): English / Issue: VII/2017

3D digitization is becoming the norm in the preservation of tangible cultural properties be it movable or immovable. In the case of mobile cultural objects, 3D models are normally acquired through non-destructive methods such as photogrammetry or 3D scanning using structured light or laser. The continuing improvements in scanning equipment which result in higher accuracy and resolution can be translated to mean higher level of 3D data acquired. At times, the quantity of 3D data of a single model can get too large and beyond what a normal work-station can process. This is where optimization comes in. However, the level of optimization will vary to suit the final purpose or usage of the 3D model. During optimization, the resulting optimized 3D model is bound to suffer from some level of data loss when compared to the original 3D model acquired directly from laser scanning. This paper discusses a practical method devised by Amber Digital Solutions in maintaining a high level of accuracy of the final optimized model for national archival purposes which requires the highest form of quality.

A SHORT HISTORY OF COMPUTER USE AT FACULTY OF PHYSICS – UNIVERSITY OF BUCHAREST

Author(s): Mircea Victor Rusu / Language(s): English / Issue: 2/2017

For physicists computing is a main activity. Starting from devising an experiment to problem solving with computer, from using mathematical tables to other aids to computation, physics has grown its strength by using each step the numerical computation. So, computing for researches as well as education was used and steadily improved by us, starting from first minicomputers to the last generation of computers and algorithms. In this presentation we will follow, in short, the evolution of computing, hard and soft, in physics at our faculty. We selected here the main field of interests that was connected with problems showing: programmed solutions, simulations and modeling, computer application and software during the time. Such a time recollection is interesting and surprises me as how diverse and far such activity was done. Examples will be from computation in tradition physics, to biology, chemistry, astronomy, medicine to data processing and visualization, data management, to create our own educational software and so on. The fields as nonlinear dynamics, complexity, chaos and fractals, as well as fluid dynamics, atomic, molecular or nuclear physics, earth or stellar physics, connected to improvement of the experiments and devices via artificial intelligence are some of our topics which will be exemplified here.

A Short Note on the Glagolitic Ornament in Pamvo Berynda’s Triod Cvetnaya (Kiev 1631)

Author(s): Sebastian Kempgen / Language(s): English / Issue: 14-15/2015

The article draws attention to two lesser known lines written in Glagolitic which are part of the Epilogue to Pamvo Berynda’s Triod Cvetnaja, printed in Kiev in 1631. Thanks to their typographic realisation, these two lines seem to have been mainly considered „an ornament“ or a „cryptographic“ element of the text in older literature. The article presents the Glagolitic text in standard Unicode encoding, so it becomes electronically searchable as such, along with a transliteration and a translation. It turns out that the Glagolitic text is nearly identical to the self-descriptions famout printer Pamvo Berynda had used before (although in Cyrillic). Another question put forth in the paper is the provenience of the actual printing types used in Kiev in 1631. A comparision shows that the letters look similar – but not identical – to printing type used around the same time Italy (Rome, Venice) or by Primož Trubar in the century before. The typographic quality of the Kievan types is, however, inferior.
