A Conceptual Approach for Industrial Internet of Things Assessment

Author(s): Luben Boyanov / Language(s): English Issue: 2/2021

The Industrial Internet of Things (IIoT) is a new paradigm that fundamentally changes the current patterns and activities in industry. The new Digital revolution transforms all sectors of human activities and production. IIoT has numerous architectural, business, technological, social and consumer perspectives. This paper looks at some reference architectures, connectivity issues, business aspects and security topics of IIoT. Those domains are looked at with their most important subdomains into a framework that can allow an architect or end user to make a quantitative assessment of a IIoT. The proposed approach uses expert evaluation of the main domains and subdomains from a reference IIoT architecture, which are then used to obtain an overall IIoT assessment.

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.

Author(s): Serhat Bahadir KERT,Filiz Kalelioğlu,Yasemin Gülbahar / Language(s): English Issue: 1/2019

In this study, effectiveness of a computer science course at the secondary school level is investigated through a holistic approach addressing the dimensions of instructional content design, development, implementation and evaluation framed according to ADDIE instructional design model where evaluation part constituted the research process for the current study. The process has initiated when the computer science curriculum had major revisions in order to provide in-service teachers with necessary support and guidance. The study is carried through as a project, which lasted more than one year and both quantitative and qualitative measures were used through a sequential explanatory method approach. The intention was to investigate the whole process in detail in order to reveal the effectiveness of the process and the products. In this regard, not only teachers' perceptions but also students' developments in their perceptions of academic achievement and computational thinking, as well as correlations between the computational thinking sub-factors were investigated. The findings showed that the instructional materials and activities developed within the scope of the study, positively affected the computational thinking and academic achievement of students aged 10 and 12 years old. The teachers' weekly feedbacks regarding application structures and implementation processes were also supported the findings and revealed some more details that will be useful both for instructional designers and teachers.

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 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.
